This is the complete guide of how to handle your battery in the most efficient way possible.(GB/ICS/JB version).
This guide refers to Android users in general (Samsung, HTC etc..) in addition to SGS2 users.
ROOT: Yes.
ROM: Any rom will do.
Kernel: Siyah/Dorimanx is preferred but any other will be fine.
Human features: Patience
After an extensive research regarding 'how Android OS works' and reading hundreds of pages (yes 1000 pages in 1 thread) in XDA regarding topics such as: BBS (BetterBatterStats), MagicConfig by geko95gek, Kernel Info, Kernel Governors, Modules, I/O Schedulers, CPU Tweaks, AIO App Configs by droidphile etc, I have come to conclusion that there is currently no better configuration than mine.
I almost don't have wakelocks, during the night (7 hours sleep) I have between 3-4% drain which is really good, of course, you can get better drain ,for example, 1 % during a whole night BUT users like that turn off their data connection OR switch to airplane mode, I really don't like doing that but of course you could do that too and enjoy your 1% drain.
Before I wrote this guide I tried these configurations in 5 different infinite sgs2 mobile phones of my friends and Nexus devices, they all were blown away from the results they experienced from their battery.
I wrote this guide because XDA users have helped me a lot in all the aspects of Android, so now I can help the XDA community too.

Post #3FAQ
When you're done with the guide please do come back and share your results with us.
I'll try to simplify things as much as I can so the common user could understand.
Let's begin,
1. Wakelocks: What is it ?
When you develop an app in Android there are options for you (as a developer) to let the app start during a different time or a different change, sometimes it is really essential, for example our build in Alarm clock(Also: Widget/Music player), we need it to start the alarm in a specific time thus this process is important and it will open up by "it self".
Counter example is a simple game or a weather app, we only use it once in a while and after we use it we don't need the process anymore so we close it, but most of the time the developer add all sort of commands to start the process even when we don't use this exact process, for example if we boot the device/click on the media app button the app will go into cached processes (System settings->Applications->Running->Click on cached processes), but let's say it's an app we use once a week or a game we play once a week, there is no need to put this app in the cached processes (since it consumes the battery) so this is why we would like to close this option.
Notice – When you open an app and close it the process is still in the cached processes because if you open it again, it will open in a sec (since it's in the cached processes)and that’s a good and efficient thing, but if you close it from the cached processes you will only make things worse because when you open it AGAIN the Android OS will AGAIN, put the app in the cached processes and this is yet again will consume the battery.
How to tell if you can turn off or not in an app/game:
Basically the idea is this,
If we are talking about an app that the whole very existence is to do things by it self (Playing songs/Setting alarms/Auto-commands apps) then of course we won't turn anything off.
If we are talking about a type of apps that their whole process is to do something particularly which will take place only when we open the app (Bar-code scanner/Weather app/Shazam/Office apps/GPS apps/Games so of course we will turn everything off.
If we are talking about ROOT apps so I suggest not to touch anything.
First thing you will do is to download Gemini App Manager 2.6.0, this app will handle these wakelocks and as we already mentioned will give us full control over 'when to put/not to put the app in the cached processes/running services'.
DON'T UPDATE TO VERSION 2.7 - THE NEW VERSION HAS NO WORKING EXPERT MODE ! ! !
After you downloaded the app, open it,
Hit the option touch key (left to the home button) and go to 'Expert Mode', you will find there, all the applications your phone contains. What we are looking for is the orange icon the says 'AUTO' under each app:
once you find an app/game with this icon, think, and ask yourself "Do I need this app/game to open up by it self?" (See the examples with the clock app above).
If your answer is "NO!" (90% of the cases the answer is no-read above when the answer is YES), then press this app/game for about 2-3 seconds, a window will open and choose 'ConfigAutorun (root)'.
A new window will appear with all sort of commands: On package added, on app widget update, After boot etc, as you can tell the name of the command does what it says for example: 'On package added' -> if you added a package to the app, the app will be put in cached process.
Change to OFF all the commands:
and there you go, this app will never fool around!
2. Monitoring the wakelocks:
Download the app: BBS
BetterBatteryStats aka BBS: Why do I need this app ?
After you managed to finish step number 1, you can now install BBS on your system.
Once your done open it and choose partial wakelocks, we will focus on this section.
Charge your device to 100% and when it reaches 10% or so, open BBS hit the options touch key and choose 'Dump to file':
this will generate a .txt file with all the apps/games that did wake your phone and caused drains.
"BUT HEY I DON'T UNDERSTAND ANYTHING FROM THIS FILE AND THIS APP IS HARD TO UNDERSTAND!!!", first you need to relax and go to the BBS thread BBS, the developer is kind enough to let you put the file there and he will look it over and tell you what is the main problem you should focus, and decide if to remove the app or maybe change something in the setting of the app.
If you want to learn about this log file and understand it better just read the thread (like I did) it contains more than 1000 pages, so after 10-20 you will have some clue about this app.
Remember, this is the BEST application that can track your battery drains and tell even if your kernel is waking up the phone, just dig in BBS and you will see, there is no other alternative than BBS, remember that and don't ask for a substitute.
Q: How can I solve BBS wakelocks on the go ?
A: Get in here.
Also, if you have EventLog wakelocks here is the solution:
Download System Tuner. open the app and go to 'Startups' and look for 'Google service framework' and over there disable both 'checkin.EventLogService'.
Be advice EventLogService wakelocks only happens with stock Samsung ROMS.
ALSO, read the FAQ.
3. LBE security manager: internet permissions & prevent apps to be put in cached after a restart: version 5+
We all know that every time we go to the inet (not via wifi) we are starting to see an immediate battery drain.
The best way is to install a firewall app (which is MUCH more than that btw and it's free) that will control our inet pipe.
The user zagzag99 was kind enough to translate the latest version (4) of that app (Notice that in Play store it's version 3 ONLY) get it here: LBE Security
After you installed the app,
Tap on More -> Permissions -> All apps
Now you are looking at all your apps/games (including system app by tapping on 'Download' on the left and choosing 'System'), by clicking on one of the app/game you would see the permissions the app wants from your phone, if it is a game that you play offline then why does this game want to go online? More-than that, why the game wants to access my call records!?
This is why you won't allow it and eventually you'll close the inet pipe and the rest for each app/game you don't want to go online or even get your precious information.
After your done we will now deal with the auto start issue.
Repeat step a, and choose a random app, as you can see the first option in every app is 'On boot permissions' so you can turn it off or back on.
Now, this is very important, I only say it once, if you see an app/game that you don't even use or use once a week 'turn it off', but if you see an app/game that you use most of the time leave it as it is, why ? Obviously you didn't read step number 1.
4. ExTweaks/STweaks& governors - Siyah/Dorimanx kernel users ONLY! **Unless you can undervolt with your kernel**
Download STweaks, if you want to understand what each command/line does please read up: Here or you can just do what I tell you to and enjoy better battery.
First of all I want to thank geko95gek who inspired me a lot regarding STweaks .
Open STweaks,
CPU tab:
MAX OC FREQUENCY: 1000000Khz
CPU_UV tab:
You can undervolt here or in setCPU (See step 5).
Be advise #1: for some reason Siyah V6b5 doesn't save the changes after reboot BUT setCPU does.
Be advise #2: Dorimanx users are good to go.
GPU tab: - SGS2 users input - Different devices try to lower 1 step back.
Siyah steps:
GPU FREQ STEP1: 54Mhz
GPU FREQ STEP2: 108Mhz
GPU FREQ STEP3: 160Mhz
GPU FREQ STEP4: 200Mhz
GPU FREQ STEP5: 267Mhz
GPU VOLTAGE LEVEL1: 850mV
GPU VOLTAGE LEVEL2: 900mV
GPU VOLTAGE LEVEL3: 950mV
GPU VOLTAGE LEVEL4: 1050mV
GPU VOLTAGE LEVEL5: 1150mV
Dorimanx steps: (Basically the default)
GPU FREQ STEP1: 108Mhz
GPU FREQ STEP2: 160Mhz
GPU FREQ STEP3: 200Mhz
GPU FREQ STEP4: 267Mhz
GPU FREQ STEP5: 267Mhz
GPU VOLTAGE LEVEL1: 900mV
GPU VOLTAGE LEVEL2: 950mV
GPU VOLTAGE LEVEL3: 1000mV
GPU VOLTAGE LEVEL4: 1050mV
GPU VOLTAGE LEVEL5: 1150mV
You're DONE!
5. Undervolting& Governors:
Be advise: If your kernel doesn't support undervolting move to the next step, but I recommend to use a kernel that has support because when the phone is in deep sleep or on 200mhz (when you're not using it) you could save a lot of battery.
Be advise #2:I am going to recommend the use of setCPU and STweaks (Siyah/Dorimanx kernel only - if you don't have siyah you can do this step also as long as your kernel support undervolt), a lot of people wouldn't recommend the use of these apps together since they MIGHT conflict with each other, BUT if you will go through this step and read carefully it wouldn't be a problem in fact, it will work just fine
Download setCPU, if you want the latest version you can buy it in the Play store (support the developer).
Version 2.2.4 would be fine too, if you want to understand what each governor means and what is cfq please read up: Here and Here or (if you’re a lazy ass user) you can just do what I tell you to and enjoy your battery:
Open setCPU,
Main screen:
change to 200-1000 Mhz (it should be like it since you already changed it in ExTweaks) and tick 'Set on boot', also make sure 'ondemand' and 'ROW/CFQ' are chosen as governor/io :
Profiles:
Make a new profile and choose 'Add Condition -> Screen On/Off' and choose 'Screen off' and save.
Hit next and choose 200-500Mhz, tick 'Set the CPU governor' and choose 'conservative'.
Choose priority 50.
This profile will make sure while the screen is off there won't be any jumps to high frequencies.
Make another new profile and choose 'Add Condition -> Battery level' and choose '10%' and save.
Hit next and choose 200-800Mhz, tick 'Set the CPU governor' and choose 'conservative'.
Priority is 49.
This profile will let you squeeze the last 10% of the battery like they were 20% but the UI will lag.
Tick those profiles and tick 'Enable Profiles' at the bottom.
Results of step a & b :
Voltages Screen: (Only supported kernels)
Be advice: This stage is the most exhausting, annoying and irritating stage you could ever find but in the end it's worth every second.Since we put a range of 200-900Mhz we will focus on these frequencies only (of course if you decide to put the range between 200-1200Mhz you will focus on them only).
We will scroll down and look for 200Mhz, 1st white row represent the default mV that Samsung has put in order to max UI, and 2nd white row represent your mV change,but we are smarter than old Samy so we will start to change.
200Mhz – Is usually between 825-875mV it varies between each phone (each phone has different ROM/Kerenl)
So you ask yourself, which mV should I choose?
Well my friends, that’s the 1 million dollar question, let's say you chose 850mV:
Touch the 200Mhz and change it to 850mV afterwards hit the 'Right icon' next to the save icon
if your phone is still working and didn't get stuck go back to the 'MAIN' tab and choose 200-200Mhz (yes exactly like that) and then we will go to the 'INFO' tab, scroll down and choose 'Stress test':
if 'Sress Test' ran for about 4-5 mins and everything is still working, you can stop it by pressing the back key and it means we can continue to the next stage.
Download Stability Test
Open the app and choose Classic stability test – this will ensure the test of only the 200Mhz frequency.
If after step b&c your phone is still working that means that the undervolt you chose is working great. (It doesn't mean that your phone won't freeze-it might), you can undervolt more and see what is your limit.
Do the same process to all the frequencies, of course if you're in 500Mhz you choose the main profile (setCPU) 300-300Mhz in order to test only this frequency.
When you're done, change back in setCPU'MAIN' tab to 200-1000Mhz, go back to Stability test and now choose Scaling Stability Test, let it run for 10-20mins, if there are no errors you're good to go.
Play with the phone for few days, if it hasn't frozen go to setCPU 'VOLTAGES' tab and tick at the bottom 'Set On Boot'.
Notice: My recommendation is to set on boot in the end of the process because if you choose a really low MV your phone might be stuck in an endless loop, thus you tick 'set on boot', only, if you are sure your system is stable.
Final Result:
[img=http://imageshack.us/thumbnmail.png]
My voltages (SGS2 Device):
200Mhz – 850mV
500Mhz – 925mV
800Mhz – 975mV
1000Mhz – 1075mV
Notice: This undervolt method is the most aggressiveness method around, if you want the easy way and you have Siyah kernel you can open ExTweaks/STweaks and in the "Undervolting" choose -25 or -50, this will undervolt ALL the frequencies together with minus 25 or 50, if your brave you can try 75.
My method gives you a specific voltage to each frequency, in 200mhz you can have minus 75mV while in 500mhz minus 50mv, this will give you the best undervolt system.
Continued on next post...
6. Freezing google/Samsung apps using Titanium Backup Pro:
If you didn't buy the app yet, well, you’re an idiot: Titanium Backup Pro or you can use a free substitute (though I never tried it) Root Uninstaller
After you bought the app, open it and go to 'Backup/Restore' tab:
in there, you can see all your apps/games AND system apps, we will be focusing on the system apps.
NOTICE: If you're using CM rom you can skip this step since they did hell of a job in removing all Samsung/Android bloat-ware.
Our main goal is to freeze processes that common users don't use and don't even know they have, I won't write all the list of the apps you should freeze but I will write all the apps you will freeze that are consuming your battery like a *****:
Email 4.0 – this is stock mail full of bugs and infinite loops that go online and check for mail, if you don't have gmail account please use a 3rd party app like AquaMail/MailDroid that will give you minimum bugs for the check interval.
Exchane Service 3.1 – Belongs to Email 4.0
Kies via Wi-Fi – I wouldn't say it consumes your battery but it's an unsecured protocol by Samsung, use a 3rd party app like AirDroid
Maps – If you're not using it FREEZE THIS APP ASAP! If you do use I suggest unfreezing every time you need it and freeze again when you're not using it (sorry).
MAPService – Belongs to Maps.
Samsung Account – Do I really need to explain? (Including all the Samsung hubs and chats and whatever they come up)
SecPhone 1.0 – If you're using a different launcher rather than TW you can freeze it.
Software Update – We don't need it, we flash our ROMS
Street View – belongs to Maps.
Talk – I find that even if I freeze it (gtalk) it's still waking the phone so your choice.
Talkback – Samsung try to overtake Whatsapp.
Wi-Fi Direct & Wi-Fi sharing & Wi-Fi sharing manager – you don't need it.
Of course if you're using stock ROM you have A LOT of freezing to do, you can use this thread and of course this amazing list
Or you can Google for more apps that are safe to remove.
7. Screen Brightness:
If you don't know, the most battery consuming part of the phone is the screen.
Go to 'System Settings -> Display -> Brightness' and choose 'automatic brightness'.
For the users that want to maximize even more (YES WE WANT EXTREME!!) try to lower the brightness as low as you can, 20-30%.
Recently I've noticed that there are new apps that you adjust screen brightness by each pixel and a lot more, you can Google that, but I prefer to be able to see things crystal clear.
8. Accounts & sync:
Everyone is recommending, in order to save battery, to go to 'System settings -> Accounts and sync' and to turn it off, of course it will save A LOT of battery, but, if you have a gmail account and you want to be notified as soon as you get an email,you can't turn it off.
What you can do is:
Hit your @gmail.com account, and 'untick' everything except 'Sync Gmail', this will assure that you will get your emails via PUSH (PUSH is the most battery efficient protocol - at real time):
Don't forget to sync your contacts/calender once in a while or before you flash a rom.
If you don't want to get your emails instantly then remove your gmail account and download a 3rd party app like MailDroid/AquaMail and set interval for every hour or every 4 hours, this will assure that there will be absolute no wakelocks but only every 1 hour or 4 ( as you chose).
If you choose to keep auto sync there is one disadvantage:
If you don't have a good reception 'sync' option will go completely crazy and keep asking to go online and sync your email (since you're on PUSH) but it won't be able to, since you don't have a good reception and it will go like this in an infinite loop till you have a decent reception and as you can already understand while your screen is off, the phone is awake and trying to sync, so keep that in mind.
9. Fast Dormacy - Should/Can I disable it ?
First of all you need to understand that not every network/operator support FD (Fast Dormacy).
My network doesn't support FD thus if I'll disable or enable it, it wouldn't make any different, in fact if you disabled it and you think your battery is now "OMG FUKCING AMAZING" this is just a placebo effect, and yes I am 110% positive.
How do I check if my network support this tweak ?
The user JIMMYMCGEE from xda made an amazing guide you need to follow (in fact it's a video clip - which is easier).
She first explain what is FD and afterwards explains how to check if you have FD and if you do, how it can save you battery.
Follow this guide and all his steps here.
NOTICE: If the app that shows you your network stats (service mode) doesn't work and only opens your dialer, this is what you need to do:
This is the code for the service mode, write it in the dialer:
*#*#197328640#*#*
When you'r in the Service mode screen, hit: Debug screen->Basic Information and here you go, service mode.
Interested in more info regarding FD ? you can read what I have already read in here.
10. Battery Calibration - Should I do it ?
The answer is simple, if you are using ICS/JB you don't have too because every time you charge the battery to 100% all your data and stats are deleted and the service begins to collect info again from the beginning you can read all about it here and here.
As you can see for ICS/JB users it's a myth nothing more.
If your using GB then you do have to calibrate your battery, there are 2 methods:
Charge your phone untill you have reached 100% boot into recovery and delete battery stats ('Advance -> Delete battery stats').
Download battery calibration app and follow the steps that are mentioned in the 'Description' of the app and in the app.
11. Network/operator modem support - How to tell if your modem meet your network standards
CM USERS DON'T USE THIS STEP IT WILL BREAK YOUR RIL AND YOU WILL HAVE NO RECEPTION
Every network/operator support a specific version of modem, this means that if you will use their modem, 90% of the time your reception will be solid without any disconnections, if your modem doesn't support, then you will sure have disconnections which will lead into more battery drains (no receptions=phone will search for antennas even though there is one).
Notice: There is a chance that even though you have or don't have their modem you might have or might not have disconnections (confused ? me too.)
How to check:
Download GetRIL, Open the app and see if your RIL/Baseband (aka modem) is matching, if they are (written in green), your good to go and you can remove the app.
If they are not, here is what you need to do:
Under 'Baseband' you have 'recommended':
You can see that LQ6 & LPB are supporting my network, we will now tap this:
and look for LPB & LQ6, after we found it we will choose it and tap: 'Download & install'.
When your done restart your phone and check again (GetRIL) that now your modem is now supporting by your network, if so, remove the app.
12. Variance:
Play store app: Hit the option touch key and untick - 'Notifications' & 'Google AdMob Ads'
When the 'notification' is on, the app is consistently connecting to the server and checking for new versions.
When 'Google AdMob Ads' is on, the app is always checking your behavior and reporting back to the Google server.
'System settings -> Location services' untick everything.
'System settings -> back up and reset' untick 'Back up my data' and 'Automatic restore'.
NOTICE: I didn't apply this step for my own device since it only saves 5% battery more or less and it's a service I use, think, if you need it or not,
WiFi users: 'System settings -> Wi-Fi -> Advance -> Keep Wi-Fi on during sleep' choose - 'Only when plugged in'.
This will close the Wi-Fi connection when you turn off your screen.
Keep in mind that after you finished using your BT turn it off, since I have specific times I use the BT I use AutomateIt, it's a great app that can control even silent modes.
Don't use Facebook app, it drains your battery the most, instead add a shortcut in the desktop for facebook.com link and go to facebook via this link, it looks exactly the same as the app since Android users don't have a native facebook app yet.
Don't use live wallpaper
Don't use widgets
Don't use Haptic Feedbacks
Never ever use Task Killer or 'Clear memory' - Android has it’s own task killer that works better than your 'decision making' brain.
Screen time out - Don't forget to set it
No reception = major battery drains - use airplan mode.
Use Nova launcher or better code efficient luanchers.
Use ad-blocking app in order to prevent unnecessary network usage in downloading ads, I recommand using AdFree - Open the app and choose: 'Boot Normally' and afterwards choose 'Download& Install hosts', when your done restart your phone.
Always charge your phone untill it shows 100% and charge it only if it is below 20-30%
Automatic Date & Time option -> untick
13. Learning to read the battery graph:
This is the final step, come back to this step after you're done with all 12 steps, reading the FAQ (Post #3) and you lost at least 70% of your battery since you charged it.
So you’re here, go to 'System settings -> Battery' and hit the graph bar.
At the bottom you can see 'Screen on' and 'Awake' we will focus on these lines.
Our goal is to achieve 100% overlap between these 2 lines, meaning, when the screen is on, the phone will be awake and when the screen is off we don't want the phone to be awake since we don't use the phone (unless we are-downloading a file).
For example if you see a blue line in the Screen on bar I would like to see at the same time the EXACT size and width in the Awake bar if not, that means we have wakelocks so we need to go to step number 2 again and see who is waking up our phone.
It's really hard to achieve a 100% overlap between these 2 bars, even for me.
Example of a minor wakelock (squared in red):
For conclusion:
You need to be able to get a MINIMUM 3 hours screen time (System settings - >battery - >screen) if not, you're doing something completely wrong.
From my experience you can't get more than 3.5 hours screen time over total use of MORE than 24 hours uptime (Maximum up time I got with the phone is 4 days with almost 3 hours screen time and 1 hour of calls.), however, if you play non-stop with your mobile, from the time you unplugged it, you will get more then 4-5 hours screen time EASY over 5-16 hours uptime:
But of course most of the users don't "act" like that and most of them just "lose" battery over uptime when screen is off.
From my vast experience with battery usage, this is it, either your get 3 hours screen time over moderate usage (long uptime-2 days +) or you get 4-5 hours screen time with aggressive use (short uptime-16 hours top).
Don't let anyone tell you different.

FAQ:
Q: Which ROM and kernel you're using ?
A: I am using Wanam ROM (latest version) and Siyah kernel (latest kernel also) CM10.1.3 and Dorimanx 9.41.
After trying all sort of ROM's I can say that the most stable and reliable ROM's are Samsung based ROM's.
I am now recommending CM10.1.3 stable ONLY!
Q: After the tweaking and following your entire guide, does the UI will lag/Games will stuck or freeze/App will run slowly ?
A: Regarding the UI you might feel a little lag (if you were using stock frequencies and voltages) or you might not feel any lag (depends on your launcher), If you install Nova Launcher and use it instead of the TW you won't feel any lag since the Nova launcher is code efficient.
Regarding the apps, you won't feel any lag unless it's a graphic app or design/CAD app (even this is questionable).
Regarding the games, you won't feel any lag in most of the games, I played a lot of games for example Dead Trigger/Galaxy on fire 2/Shadowgun/Samuraio II and few more, I didn't feel any lag or what so ever, though I did feel that the loading steps took 1-2 more minutes.
Q: The most used (or 2nd) most used service/app in BBS is 'AuidoOut', how can I minimize it ?
A: You can minimize the 'Audioout' by unticking: 'System settings -> Sound' , under System, untick them all.
Plus, in the same window click on "Vibration intensity' and put 'Vibrate on screen tap' on the lowest (0).
Q: I keep getting "Shell have been granted superuser permissions" over and over again and it drains my battery, is there a solution ?
A: It's a known problem with SuperUser, install SuperSU give it root permissions via superuser, go to app info of superuser hit "Force Close" and afterwards hit "Disable", now SuperSU will handle your root privilege.
Q: I froze Secphone.apk and now I am having weird issues what should I do ?
A: Obviously you're an idiot since I specifically wrote next to SecPhone.apk: If you're using a different launcher rather than TW you can freeze it.
So don't freeze Secphone.apk if you are using TouchWiz launcher which is the official launcher by Samsung.
Q: How can I tell if my phone is going into Deep sleep and activates the setCPU profiles ?
A: In setCPU go to 'Info' tab and tap 'Time In State', you will find a pie chart, if your a common user-that most of the time his screen is off-, you should see that 200mhz has the biggest chunk, if it's not the case then check BBS what is waking your device.
Q: After installing Gemini App Manager I am unable to install/uninstall any app, what should I do ?
A: You are probably using Screen Filter app, for some reason the install button become unresponsive, disable Screen Filter when you need to install something and enable it again afterwards - Thanks Ryther.
Q: How can I solve BBS wakelocks on the go ?
A: Get in here.
Also, if you have EventLog wakelocks here is the solution:
Download System Tuner. open the app and go to 'Startups' and look for 'Google service framework' and over there disable both 'checkin.EventLogService'.
Be advice EventLogService wakelocks only happens with stock Samsung ROMS.
More to follow.

Thank you for your positive feedback.
Thanks
I can confirm getting about 3~4 hours of screen time at most during 16~24 hours of usage.
I noticed you wrote something about SetCPU working on stock kernel ... in my experience it does not work even if some people claims so.
SetCPU might be able to change between a limited amount of Governors, but setting Min and Max doesn't work even it looks so (I used some other tool to confirm this). I only tried this on rooted Stock GB, but I think it will be the same on ICS.
Does this work on jb rom?

great tutorial, thank you for your effort!
I followed the steps but I can't find this one in LBE security:
"c.After your done go to the first window (swipe your finger right to go to the first screen)
d.Choose 'Speed boost -> Auto-Start' you will see all the apps that will be put in the cached process EVERY restart you make to your phone, now, this is very important, I only say it once, if you see an app/game that you don't even use or use once a week 'Disallow' it, but if you see an app/game that you use most of the time leave it as it is, why ? Obviously you didn't read step number 1.

Thank you for your positive feedback, please do come back with results and post them here.
As you can see in the picture, this is the first screen you see when you open up LBE,2nd raw is 'Speed Boost' just click it and it will show you new buttons, there you choose 'Auto-Start.
EDIT:
I have added pictures to the main thread for most of the steps and marked in red the specific step.
I got confused because in my app it says phone accelerate instead of speed boost
anyway, I'm using these mods since this morning so it is too early to say anything factual about battery life, but I think it is much better...
usually I would have about 60 or less % left at this time of day...

Perhaps you downloaded even newer version than mine but I can see you figured it out.
If you used to get 60% and now it's 76%, of course this is an amazing change.
Don't forget to check your screen time before you charge it and make sure it's minimum 3 hours (if the total up-time is above 24 hours).
If you did follow all the steps and did everything as I wrote, I suggest to get into Recovery mode -> Advance -> and reset battery indicators.
or wait 1-2 charges and the battery meter is supposed to acclimate.

I saw really few users like your self that actually got that time, but I had never got more then 3.5-4 hours max screen time on uptime for more then 24 hours.
I even did EXACTLY what these users told me with their exact config (from 3 different users) but again, I got only 3.5-4 hours screen time max.
So this is my conclusion.

Yea that's an annoying bug that is happening from time to time.
Just exit the app and open it again.

This thread will only contain detailed but simple and easy to understand information and broken english because I'm Mexican and I live in Mexico.
This is my first thread in XDA, this phone is my first smartphone or touchscreen phone I got it a year a go when It came out and this post will have all my knowledge about SGS2 battery saving tips I've got from this year.
Some settings might sound dumb, like why would you disable a core if you paid for two, and why would you want lower brightness if you have a SAMOLED+ screen which is brighter than SAMOLED HD, well those settings are optional and you have to find which ones will help you when you need battery badly for an emergency or something.
First let's make a list of all the apps that you need to use and what they will do, all the apps and tips are optional but if you use all of them you will have some amazing battery life!
*This thread only contains free apps so you don't need to spend $ at all!*
#1 Screen filter: https://play.google.com/store/apps/...ch_result#?t=W251bGwsMSwxLDEsImNvbS5oYXhvciJd
This app is really useful because it allows you to go on lower brightness than what your phone allows you to! and if you have sensitive eyes it'll help at night, when I really NEED BATTERY I lower the brightness as much as I can (Don't go too low because you won't be able to see s**t.
while in use, screen filter make the install button in the package installer unusable; if you want to install an app, disable screen filter first
#2 Rescan Media ROOT: https://play.google.com/store/apps/...SwxLDEsImNvbS5hZGR6Lm1lZGlhc2Nhbm5lcnJvb3QiXQ..
This app will allow you to enable and disable media scanner whenever you want. Media scanner drains ur battery a lot specialy if you're using a JB ROM! I don't know if it'll be useful with GB/ICS because I only tested it on a JB ROM, by disabling media scanner you won't be able to see pictures or videos from your gallery but you're able to play music, use this when you really need to save battery and you're not gonna use gallery.
#3 https://play.google.com/store/apps/...sMSwxLDEsImNvbS5yb290dW5pbnN0YWxsZXIuZnJlZSJd
BE CAREFUL WITH THIS APP! IF YOU'RE NOT SURE OF WHAT YOU'RE DOING ASK AN EXPERIENCED USER OR JUST LEAVE IT!
Titanium backup has an option to uninstall system apps but this one is free, just use it to freeze apps that you don't use and are always running, the apps I disabled are:
*Maps (I enable em when I need them)
*TvOut
*AccuWeather
*Movie Studio
*TalkBack
*Apollo (I use PowerAMP)
*Sound Search
*Voice dialer (Useless IMO..)
*SIM Toolkit (I don't know if this is safe to remove for all users but I had no problem)
*Trebuchet (I use Nova Prime)
*News & Weather
And you can disable other apps that you don't use, those are the ones I disabled.
#4 Startup manager: https://play.google.com/store/apps/...wsMSwxLDEsImltb2JsaWZlLnN0YXJ0dXBtYW5hZ2VyIl0.
This is my favorite, I don't know how useful it is but I hate to have apps I don't use running or on the background.
With this app you can disable the user and systemapps that auto start when you turn on your phone, they will start without any problem when you need them!
This app will give you more free ram! I don't know if the RAM on phones consume as much energy as PC RAM but I used it anyway..
The system apps I disabled are the following:
*Youtube
*Clock
*Email
*Download manager
*Media Storage (I guess you don't need this is you disabled media scanner already with the previous app)
*Gallery
Those are only the system apps, remember to disable YOUR apps that are always running on boot and you don't need them to be running (I only kept facebook, facebook messenger, nova launcher and whatsapp) I don't suggest you to disable many google apps, I think it gives problems when trying to connect to google servers (NOT SURE) disable them if you want and if it give you any problem just enable them again.
#5 FastDormancy Toggle: https://play.google.com/store/apps/...W5tb3JhbC5mYXN0ZG9ybWFuY3l0b2dnbGUuaTkzMDAiXQ..
First do a google search and check if your carrier supports FD, my carrier doesn't support it so I disabled it and you can uninstall this app after disabling it if you want.
#6 AdFree: https://play.google.com/store/apps/...DEsImNvbS5iaWd0aW5jYW4uYW5kcm9pZC5hZGZyZWUiXQ..
This app gets rid of the annoying ads, they consume battery because they use 3G to load and they're annoying anyway, just install it and after it downloads the host files and installs them you can uninstall this app if you want, if you start to get Ads again just install it again and update the host files and uninstall or you just can keep it and let it download the new host files.
#7 GetRIL: https://play.google.com/store/apps/...t=W251bGwsMSwxLDEsImNvbS5zaWJib3IuZ2V0cmlsIl0.
Some users have better batterylife after matching their RIL with the current modem, you can uninstall this app after installing the right RIL but I think the RIL will keep changing everytime you flash a new ROM. This app is supposed to keep you away from RIL crashes, try it. and uninstall after using it.
Ok that's it now let's move to the tips, some of them might have you tired already but I'll put them for the new users.
#1 If you're not gonna browse, use facebook or any app that requieres 3G just disable it, I have 2G most of the time because I only use whatsapp and gtalk the most.
#2 Disable WiFi, GPS, Bluetooth and Sync if you're not using it.
#3 Disable google now (It improves battery a lot according to some users)
#4 If you're lazy to control your brightness just set it automatic, I use the notification bar slide brightness from CM10 and I always have it really low.
#5 Try not to have too many root apps running on start up because SU makes the phone laggy when it tries to enable too many root apps.
#6 If you have a weather app set "refresh manualy"
#7 If for some reason after using all the apps from above you still have unwanted apps running just stop them manualy, I check running apps really often and stop them.
#8 Some people have better battery life with different modems, I always use stock modems so try different modems and check which one suits you better
#10 Don't let your phone charging overnight
#11 If you're REALLY need battery and you're on a trip only listening music with the screen off, set your CPU to 200 Mhz or 500 Mhz if you want, Music player is a light app but some music players keep going from 100-200 mhz to 800-1000 ..
#12 Try to enable the skip track with volume key from CM10/AOKP, this will save battery as you won't turn the screen on everytime you want to skip track and If you use the 200 Mhz max frequency you won't have to go through the lag to skip a track (If your galaxy lags a lot at 200 Mhz, some phones don't lag that much at that frequency)
#13 Disable BLN
#14 If you're not using the internet at all put flight mode
#15 Use dark or black wallpapers and themes, our SAMOLED+ Screen saves energy if you use black/dark themes/wallpapers
#16 If you have facebook and you need more battery try to log off your facebook and facebook messenger, it'll save you some battery (credits to Obagleyfreer for this tip)
Now let's get into the ROMs and Kernel subject.
I'm using Dorimanx 7.3 and I'm using JellyBam ROM at the moment but I change ROMs really often, I think JellyBam has vsync enabled so I guess a ROM without vsync and Dorimanx 7.3 will have better batterylife.
ExTweaks settings:
Easy.. Just go to recovery and go into specific kernel options and put Battery profile.. If you have ExTweaks plus you'll be able to change the profiles from the app and you'll see the Extreme_battery profile, enable it if you have ExTweaks plus.
After you set battery profile go to the CPU tab and put second core always off if you're just chatting and listening music you don't need both cores enabled.
Oh yeah and undervolt your CPU/GPU in ExTweaks, I have CPU UV -75.
If you did a charge cycle and your phone is at 100%, unplug it and go to the MISC tab on ExTweaks and Reset Fuel Chip and charge it again to 100%, I usualy reset it like 10 times after flashing a ROM, I unplug and reset and plug and like that a few times.. I'm not sure if it helps at all but I do it anyway.
**I think some users reported that slower charge gives better battery, in ExTweaks MISC tab theres an option for charging voltages, set the lowest AC/MISC:550mA USD:450mA (I haven't tested it but I will do it soon**
I'm adding more info to this thread and giving credits in a few minutes I have to eat dinner.
As I explained I'm from Mexico and this is my first help/guide thread in XDA, If you liked how I shared all my knowledge and want to help me with a donation feel free to do it, I'm from Mexico as some of you know this country is really poor and even 30 cents or 1 USD will help me, 1 USD is like 13 mexican pesos.. feel free to donate if you want, any amount will do fine.
Ok after trying to discharge my phone using Max brightness, both cores enabled, screen on all time, PowerAMP on speakers all the time with max volume, 1.5Ghz, Extreme_Perfomance profile I got 3 hours 30 mins screen time.. I couldn't take a screenshot cause I took too long to take it and I had media disabled Now I'm going to try with my settings and post the results! Please if you tried my guide and got amazing battery life post a screenshot of your battery graph and screen on time or tell us the results!
Mexico loves xda <3

Great instructions.I am using JellyBam ROM 20121022 – i9100 daily [OUT DA SPACE REL] with siyah v5.0b1
Well i underclocked my device to 100-500 mhz with 2 cores running all the time... voltages as low a i can... gpu 40 66 100 mhz... the only thing i took from this thread is the screen filter,thanks for that! now i usually get 7 hours screen time 2 days running

Your welcome You should try the startup manager to get rid of the apps that auto start!
A handy tip to help battery life is remove Facebook app. It is a HUGE battery drain.
The best thing to do is to log onto the Facebook Mobile site then when you're on the homepage just save as a bookmark.
Now you can add the bookmark to your home screen as an icon.
It's just like Facebook app only faster, less bugs and battery friendly

One thing though: I would advice you NOT to fully drain your battery unless absolutely necessary. This will lower the full capacity of your battery. It's the same thing that happens to laptopbatteries. Many people let it run dry from time to time and this is one of the reasons people experience such a severe hit on laptop battery capacity over time.
This is also the reason why you phone will shut down before battery hits 0%. It's simply to spare the battery from degradation.

Just to know if you guys want something for my rom
Battery Life. Even Underclocking isn't increasing battery life with BORETS24's kernel, do something that'll increase the SOT ! I don't get more than 3 hours of SOT with any ROM, Kernel.
Stable gps during using waze or other gps app....no more gps lost connection plz
i would expect a simple build, with no bloadware and of course stable even with a a501cg. iirc most problem are with that device.
list of expectations(mine and the others)
- stable
- no bloadware
- simple installing/autoinstaller (there is a simple-to-customize autoinstaller mentioned in this forum)
- possible to choose gapps installing by choice in one install process.
- gps
- led functional
- battery life
Simple Rom (like a pizza without any topping. User can select toppings )
Stability (GPS, wifi, data connection, bluetooth, and of course the device itself. Sudden restart is really terrible.)
DT2W/S
Battery life
LED with color (if possible)
I'd love to have another UI. To get the CM12.1 drop-down menu instead of Asus one.
Provide and alternative to borets' kernel: it has great features, but for me was and keeps to be more battery eating (I think due to the dt2w and overclock integration) than even a stock one.

Installed CM12.1 your version found at windroidica website and found some bugs. Can't set contacts photos, it always says "No pictures on phone". Can't leave a comment on videos through youtube app and. No editor found in Gallery app? I need some help because I just flashed this rom yesterday.
if based on stock..
remove all bloatware..
pre rooted..
pre xposed..
g apps as separate package..
ota for future updates..
adb sideloadable..
the list is unlimited..
Since there are no threads on how to improve battery life I figured I would make one for all the lazy people out there
Let me start by saying don't be me! Use elemental x kernel and just freaking pay 3.99 for ex kernel manger its so worth it!!! It is an amazing app and kernel combo:good:. On stock rooted I was barely pulling out 2 hours screen on time with battery tweaks and low signal all day (no signal at my school) and 2.5 - 3 hours where i had a good signal. With the tweaks i am going show you I am getting 4 hours consistently and 5 hours on a good day.
THINGS YOU WILL NEED
i think this goes without saying but root access...
Build.prop editor or knowledge of how to edit it
Ex kernel installed on your current rom
Ex kernel manager (3.99 on google play... just pay for it... no free version exists help the developer out)
Usb cable and computer or a file manager
Greenify
1). add these lines to the build.prop
ro.mot.eri.losalert.delay=1000
ro.config.hw_fast_dormancy=1
persist.cust.tel.eons=1
ro.ril.set.mtu1472 =1
wifi.supplicant_scan_interval=497
pm.sleep_mode=1
power.saving.mode=1
ro.ril.disable.power.collapse=0
ro.vold.umsdirtyratio=20
2). Install ex kernel and wipe cache
3). Verify that you have it installed by going to settings/about phone and look for kernel version it will say elemental x somewhere in it if you installed it
4). Buy ex kernel manger for 3.99 on the play store (believe me it works)
5). Open the app and click the 3 lines on the top left and click cpu.
6). Scroll down to "Governor options..."
7). Now click save and make a name for your stock profile. (yes it is a needed step!!! it makes a folder you add files too):good:
8). Download ghost pepper or butterfly. (or any other one but those two are recommended for better battery life) You can pick which one gives you best battery life. The process is the same for all of them and its very easy to switch between them.
https://docs.google.com/spreadsheets/d/1P1LXnJnUdz9cC_qpcwMpfParUBlaPbIhyLZHOWjknUE/edit#gid=0
9). If you did step 7 right you will see a folder on the root of your internal storage called ElementalX inside that folder is a folder called gov_profiles. If it is not there read step 7 again. Copy the profile you picked here and remove the file extension. (IMPORTANT!) example instead of ghostpepper.txt you would rename it ghostpepper
10). Go back to the ex kernel app and click load. you should see the profile you just put in that folder and check it. If you want your settings to stick click apply on boot
11). Go back to the 3 lines and click miscellaneous this time.
12). Set your i/o scheduler to noop and click the power button on the right. That makes it apply noop on boot
13). Click fsync and disable it then click the power button again.
14). Download greenify from the play store its free
15). Open the app (grant it root) and click the plus button in the top right
16). Add apps that are keeping the phone awake. Snapchat and Instagram are two GREAT apps to put on this list because they eat your battery alive even with the screen off.
17). When your done click the check in the bottom right.
18). Click the 3 dots make sure it says "disable auto-hibernation". if it says "enable auto-hibernation" enable it.
19). Click the 3 dots again and click settings. make sure your working mode is root and check shallow hibernation and aggressive doze
YOUR DONE! If you have anything to add or disagree with me please don't be shy and comment. We can only improve this phones battery life by communicating
I get 5-6 hours stock rooted with no added build prop lines or governed tweaks. I didn't like the performance loss with ghost pepper and butterfly, and the battery improvement wasn't even noticeable. But everyone's results vary I guess

8). Download ghost pepper or butterfly. (or any other one but those two are recommended for better battery life) You can pick which one gives you best battery life. The process is the same for all of them and its very easy to switch between them.
https://docs.google.com/spreadsheets/d/1P1LXnJnUdz9cC_qpcwMpfParUBlaPbIhyLZHOWjknUE/edit#gid=0
9). If you did step 7 right you will see a folder on the root of your internal storage called ElementalX inside that folder is a folder called gov_profiles. If it is not there read step 7 again. Copy the profile you picked here and remove the file extension. (IMPORTANT!) example instead of ghostpepper.txt you would rename it ghostpepper
10). Go back to the ex kernel app and click load. you should see the profile you just put in that folder and check it. If you want your settings to stick click apply on boot
11). Go back to the 3 lines and click miscellaneous this time.
12). Set your i/o scheduler to noop and click the power button on the right. That makes it apply noop on boot
13). Click fsync and disable it then click the power button again.
14). Download greenify from the play store its free
15). Open the app (grant it root) and click the plus button in the top right
16). Add apps that are keeping the phone awake. Snapchat and Instagram are two GREAT apps to put on this list because they eat your battery alive even with the screen off.
17). When your done click the check in the bottom right.
18). Click the 3 dots make sure it says "disable auto-hibernation". if it says "enable auto-hibernation" enable it.
19). Click the 3 dots again and click settings. make sure your working mode is root and check shallow hibernation and aggressive doze
YOUR DONE! If you have anything to add or disagree with me please don't be shy and comment. We can only improve this phones battery life by communicating

Maybe giving your app usage / connectivity usage will help too.
Are you using Bluetooth / NFC / ... ?
Facebook ? Messenger ? Whatsapp ? ...
Anyway, I will try your method and give result after the weekend !
ex kernel manager has already all profiles added and built inside about governors... he added all of them somedays ago, so, no need to download each file and put them into the relatives directory as stated

I do not use Facebook app or messanger. I use chrome notifications and Facebook.com. it works great like that. Don't use what's app and I just kinda of assumed people would know how to turn all that off and screen brightness down a bit

I get 5-6 hours stock rooted with no added build prop lines or governed tweaks. I didn't like the performance loss with ghost pepper and butterfly, and the battery improvement wasn't even noticeable. But everyone's results vary I guess

For sure you don't have any social media apps like messenger, snapchat etc?! I get 5hrs the days I don't use any social media apps, only browser, wifi and low brightness..
is elemental kernel necessary to add those build.prop lines? Or can i add them and still get the benefit without the kernel?
What exactly are those build.prop lines for?

You can look them up individually but most are for battery improvement under low signal.
Thanks for the guide. I already had this set up except for the lines and greenify
What are the side effects of the lines in build prop? (will it work in pure nexus or maybe it already has something similar..?)
Sent from my Nexus 5X using Tapatalk
I don't know, maybe it's just a placebo effect, but before adding those lines, I had some serious drain on mobile data. Today I was quite shocked, because it drain much much less! I'll give some feedback after a while. Maybe my 5x just had a good day today haha.

My experience was excellent battery life with glassfish 1.2 but worse performance than HawkTail 1.2. Sticking with HawkTail 1.2 since battery life is still very good.

There's a lot of threads out there regarding battery saving techniques, but I didn't really see anything that went into a lot of detail on the OP3t. I own both an OP3t and an OP5T, and after running into some issues with the battery I have finally gotten my phone to idle fairly well on the devices and figured I would share my techniques.
Anyone that reads this and finds this useful, I encourage you to let me know the outcome of your battery after following this guide. Also if you have any suggestions/recommendations, please share them with me on here. I can update the original post and include your suggestions so that it can be helpful for other users as well.
The wakelocks category can be pretty intimiating because it's different for all users based on applications they have, but if you have some custom regex wakelocks or just standard wakelocks that you would like to share, please let me know.
Now to the guide...
Phone Specs:
OnePlus 3T - 64Gb
OxygenOS 5.0.3 (stock) & rooted with Magisk
Kernel - Bane Kernel https://forum.xda-developers.com/on...e-development/kernel-bane-kernel-r-1-t3801778
Recovery - https://androidfilehost.com/?fid=890129502657595792
Developer Options:
Developer - On
OEM Unlocking - Enabled
Advanced Reboot - Enabled
* Doze mode * - Disabled
-I need to highlight this, because I usually enable this option, and I know many others do as well. I'm not sure if my situation is an anomaly, however I must highlight if you use 3rd party battery saving apps such as naptime, forcedoze, leandroid, you should disable this mode. If you don't use these apps, then you should be okay to enable the option. I had this option enabled initially while using the 3rd party apps, and they were conflicting with my phone and my battery was draining very rapidly. It wasn't until after I disabled this option that I noticed a significant improvement with the battery.
USB Debugging - Enabled
Verify apps over USB - Enabled

Xposed
The modules I have enabled are:
Amplify
ForceDoze
No Device Check (this is a xposed module you can download from the app that helps make SafetyNet check pass)
Now in Android Settings --> Data usage
Click on the cellular data usage as well as the wifi data usage, you can click on an app that shows up in that list that uses up a lot of data and when you click on it, there is an option to toggle off the option "Background data"
I'm not sure if this is really needed, but what I did is I went through the apps that used the most data (including google play store and google play services) and I toggled the background data off
Android Settings --> Battery
Click "Battery Optimization" --> click the ellipses (top right corner) --> Advanced optimization --> turn this on
Android Settings --> Apps --> Special Access --> Usage Access
Turned off for google play store and google play services
Android Settings --> Apps --> Special Access --> Unrestricted data access
All apps are turned off
These are all my custom settings. If you would like to share any, let me know!
Probably you didn't search enough.
There are many helpful topics here or at Oneplus forum for Amplify, Betterbatterystats or with guides for increased battery.

There are several very useful posts each individually spread around these forums; the purpose of this thread is to have a unified source so people don't have to look all over like I did. I know you initially posted on my thread when I had terrible battery drain issues; and after I posted the information you requested, I haven't heard anything from anyone so I had to troubleshoot and fix it on my own. I guess what I'm saying is, I just want to help others in case they run into a similar situation because it can be frustrating when you're seeking guidance or help and no one responds.
I use Naptime and also had enabled the Doze mode in the settings, so like you say i disabled doze mode now and kept naptime running , ill update this post with my findings

Yeah, keep me posted. I'd be interested to see if your results are similar to mine. Were you also having a lot of battery drain despite using naptime and doze mode?

@manohar3787 - curious to hear about your phone after turning off doze. Any updates?
Leandroid app is responsible of a severe wakelock, I think is almost better not to have it? Any opinion?
Also, what about RILJ And RILJ_ACW_WL wakelocks? Are these safe to block?
Sent from my ONEPLUS A3003 using Tapatalk
RILJ was safe to block on nougat and below, but in Oreo+ it will actually cause a lot of trouble with the system. The other wakelock you mentioned "RILJ_ACW_WL", I'm not familiar with. What I woudl recommend is do a full backup in your recovery, then make the change to observe what happens. If it messes things up you can recover from your backup.
Regarding Leandroid, I haven't really heard any concerns with it. There have been some responses of users that didn't find it to help any, but I haven't heard of it having an adverse affect.
Another app I haven't tried, but am tempted to try at some point is called Island: https://play.google.com/store/apps/details?id=com.oasisfeng.island
Also a thread about it here: http://forum.xda-developers.com/android/-t3366295
@xNAPx - how is your SOT and your idle battery like? DO you use any 3rd party apps/tools to help with battery drain?

My SoT is dependent on the usage, night drain is less than 1% a hour even 0% sometimes, SoT is between 7 and 5 h
About those wakelock I've heard the same about RILJ on Oreo, about the other one I don't know but is heavy as well.
About Leandroid I'm not very convinced. It messes up with notification and now I have another big wakelock to worry about

Unable to End Google play services
i am unable to doze google play services since am already running doze mode+magisk modules(sysconfig patcher + enable doze moe for gms )
Still i can see play services in Running services
Kind help needed
@xNAPx - do you have any custom settings or tools you use? Do you use Greenify?
What are the big wakelock issues that you have trouble with? Is it the one you mentioned "RILJ_ACW_WL" or other ones?
@Anusha Rao - Are you using doze mode within the Android system or 3rd party tools like I posted?
I don't think you want to use both magisk modules. As I mentioned in my post, I only use the sysconfig patcher. And make sure you reboot the phone after enabling that.
To check and see if google play services is being optimized for battery try going here:
Settings --> Apps --> Application List--> Google Play Services --> Battery
When I look at mine it shows 0m in use
0% battery usage
Battery Optimization:
Optimizing battery use
EDIT:
I'm posting screenshots of my googple play store and the google play services having battery optimization enabled and using 0% battery.
BTW, just so we're on the same page, you shouldn't completely "stop" google play services because it's essentially what drives the OS. Those services are important for letting your phone operate correctly. My thread is about optimizing those services not disabling/stopping them.
If you want to completely "freeze" certain apps and services you can try out that application I posted in my previous post called "Island". I'd be curious to hear how it works out.
That one plus "RILJ" plus "LEANDROID service" (which I un installed) , and also "AudioMix" and "xalarmx"

Amplify tells me I need to root my device but I have Magisk installed...?
I'm not familiar with the rom that you have "Dirty Unicorns". I use the stock ROM.
Most custom roms have root built in though so you might not even need to use magisk or super SU. You can check to see if there are any custom rom settings o maybe go into developer settings and see if you see a "Root" option.
Face unlock is not supported in the "Bane Kernel".
Does Lean Droid caused more battery Drain?

Disable background data in Play Store and Play service will not disabling them right?
@Bintang Ksatria - Leandroid should be using less battery. @Rvl7 - No it won't disable them. I still use them, but it's on manual load, and not in the back ground. At least that has been my experience.
