Ayo mates.
So who doesn't have battery problems? Probably everyone has. Even if you don't you'd want more ? huh ?
So after owning the phone for almost 3 months I had serious variations in battery life from 10 hours screen on to 7 hours screen on (*cough* 4.1.2) and back to 10 hours with xxdmb6 (YEAH!)
Also the screen off consumption.
So I am gonna talk about wakelocks in this thread. So what can use battery when you aren't using your phone... can also use the battery when you are using it. So fixes or possible fixes should improve the total battery life as well.
This thread is divided into 3 parts - basic tips , wakelock fixes and advanced fixes.
Install BetterBatteryStats. This is gonna monitor the wakelocks and the elements that drain the battery.
Tip 1 - (Install CurrentWidget) If you keep charging the battery even after it has reached 100% you will see that the battery continues to accept charge. This is true. If you charge the battery till it stops accepting power(by monitoring it through currentwidget) you will see that 100% lasts for a long time. i mean that suppose your phone uses 1% battery per 10 minutes, now if you just unplug and start using the phone, it will stay at 100% for a long time.
But this may even damage your battery. I am not sure. I do it considering how much technology has advanced.
Tip 2 - So from wanam's thread -
wanam said:
Disable auto sync for accounts if you don't need it
Disable GPS (and wifi gps) when not in use
Disable auto backup of Google account
Set brightness level to automatic
Disable motion if you don't use it
Check your apps settings and disable useless background sync
Disable useless animations

List of general Wakelocks -
PowerManagerService - It is a sum up of partial wakelocks.
MultiPDP - This indicates a high network usage(2g/3g/4g).
AlarmManager -
AlarmManager provides access to the system alarm services. These allow you to schedule an application to be run at some point in the future. When an alarm goes off, the Intent that had been registered for it is broadcast by the system, automatically starting the target application if it is not already running. Registered alarms are retained while the device is asleep (and can optionally wake the device up if they go off during that time), but will be cleared if it is turned off and rebooted. The Alarm Manager holds a CPU wake lock as long as the alarm receiver's onReceive() method is executing. This guarantees that the phone will not sleep until you have finished handling the broadcast.

These are the findings of asksven, so have been quoted. So it is a sum up of different wakelocks again
AudioOut_2 - When apps run in the background that use sounds, this wakelock is always there.
deleted_wake_locks - A wakelock that is no more, generally when you turn wifi or data or gps on and off. But it still reflects wifi wakelock. You can sum it up as a wifi wakelock and some other wakelocks.
network-location - This is a gps wakelock.
wlan_rx - Wifi wakelock
wlan_wake - Wifi wakelock
mediaserver - when something uses media files or may even when you play heavy games like real racing 3 which uses data on internal sd card
l2_hsic - A possible explanation is unplugging the charger while phone is asleep.
I have attached a pic. You can see the difference
Wakelock Fixes
AudioOut_2 - AudioOut_2 is a major wakelock on many devices. The solution is simple. Before turning the screen off. remove all recent apps and in task manager , go to ram tab and hit clear memory. Then close task manager and swipe it away from recent apps as well. Then lock the phone. Alternatively you can download advanced task killer. (Viber seems to cause this on many devices.)
MediaServer - Flash the attached fix via a custom recovery. Someone posted this and said that he got from alliance rom ota app. I asked the Dev and he said that I can use it but it may cause a boot loop. So keep nandroid a ready. Credits go to comnam90.
Other fixes could be to download Rescan Media Root. This app fixes wakelock but it might still come up sometime.
If you are comfortable with decompiling try this.
l2_hsic - This wakelock is incorrigible. But possible fixes are in thread. I will jot down what works for me.
NetworkLocation/SignalCollector Hierarchy - Many wakelocks happen due to this maps app. This is because maps app try to update the location of the device. Modify the settings according to the image attached. But better is to disable all location services. This will also decrease AlarmManager wakelock.
But if you really don't use maps then best is to Freeze local app, maps app, navigation app. This wouldn't harm the phone as they can also be downloaded from play store which means android os can cope without it.
Processes - There are many user apps which are a necessity but eat up the battery. We can't freeze it nor uninstall it due to the need. What can we do about 'em ? This is where Greenify comes in. Don't let the uber simple UI fool you. The app is simple and self explanatory. I have greenified almost all the apps and this app doesn't eat up your battery !
I will be adding more as I find more...
Advanced Fixes
These aren't very advanced if you know what you are doing.
Try another kernel. (like perseus, uneak, redpill). I find almost similar results but it may vary as we move to the next parts
Undervolt(CPU). Believe me it will help. You should start off by reducing each voltage by 25m for each step. This requires a custom kernel and a compatible app. STweaks for redpill or perseus or uNeak Engine for uneak kernel.
Do stress tests after reducing value. It is recommended not to go below 800mV.
Thanks!
One of the best things I did to save battery is to remove Facebook and Viber.
Now I'm trying to Greenify Facebook. I hope it will not do any wake locks.
Nice article Utkarsh.
Those are general wakelocks, but there are others as well, like in the attached pic.
Btw- What's that wakelockfix.zip?

That wakelock is generic with exchange services. Remove it to get rid of it.
Well that will probably fix media server. It did for me but I will see if it comes up again.

Well you gotta try hampering with update settings. I am a student and not in business so email delay is not gonna hurt me at all.
It would hurt business men(that's what I derive of you) or someone whose most work is done through mails.
Nice thread, but I'd like to chime in that wakelocks aren't necessarily an absolute evil. You will always have some wakelocks, and it's supposed to be that way. Network, wifi, location services and some apps won't work properly without being able to wake the phone from time to time. It's when these wakelocks sum up to a considerable ratio of your uptime that you should begin to worry.
Might I also suggest you add greenify to your list of countermeasures.

Hi, just one question, why not go below 900mV? Is there any reason for that? I´ve got my Note 2 uVd to these values (762, 775, 800, 825, 850, 875, 925, 950, 1000, 1050, 1075, 1125, 1150, 1175, 1250) for the frequencies from 200Mhz to 1600Mhz, I don´t think it wil harm it as I´ve been running these settings with RedPill Kernel and STweaks app for a couple of months now and I haven´t had any freezes at all or any issues, could you explain why it´s not recommended to go below 900mV? Is it just for the different tolerance to uV every chip has? Thank you anyway for your marvelous post and for the greenify app, looks promising, I´ll report how it goes since I´ve just started using it today, thanks.

Audio out 2 for me has been causing an annoying battery drain. Turns out viber is causing it for me. Yesterday it was the best part of two hours.
Today I quarantined viber and my audio out 2 dropped to 6 seconds after the phone being on for 6 hours. Half an hour ago I re started viber and my wakelock now reads 22 minutes. So I have now uninstalled viber.
How this info helps others.

Try an app like BBS

SInce Greenify works with the new MOFO method, I thought it would be interesting to see how it's affecting the Turbo's already superior battery life. How much further are people getting on a single charge?
i completely forgot about that. i will let you know. may take a couple days though to really see.
I've been using greenify since owning the turbo. Without xposed, root only allows for hibernation without having to turn the screen on. Otherwise, I haven't noticed much of a difference - though it is nice not watching the screen turn on, stop processes, then turn off many times a day.

i thought without root it could not autohibernate. before root you had ot manually hit the button to close apps. at least i couldnt find a way to have it auto hibernate without root

No it can auto hibernate without root. You just have to set greenify as a device administrator - and it has to turn the screen on to stop apps. This function may require the paid version (dont remember), but not root. I think root may also allow hibernation of system apps, but even then I think that was an option without root.
Sent from my mobile device
does not work 100%?
My workaround was to use fast reboot pro since it stops apps without root or turning on the screen.
Haven't rooted my turbo yet (not paying for it when they give disclaimers and there was a bounty) but frp seems to save some battery plus switching to ART helps as well.
I don't think greenify will do much difference because it requires more of cpu downclocking and Governor change.

Huh? Greenify does not "downclock" or change your governor. It keeps wake locks down, and prevents apps from using battery by running when they don't need to be.

I am well aware of that. My lack of not seperating the sentences may have brought confusion. What I was implying, was that greenify won't do so much of a difference because to obtain legit battery improvements it requires tweaking of kernel and cpu and governors and achieve the best battery possible.

Do not be mislead to how many hours it lasts in the long run of quantity but focus on screen on time which matters most. I am not rooted whatsoever and I constantly achieve this battery life.

I see. I do think greenify does its job, and certainly helps battery life (especially in conjunction with xposed). I would, and I am sure many others would agree that it's still an effective and legitimate tool. I agree, not as much so as throttling, but that's not really what I thought this thread was about. We are unfortunately far from kernel tweaks at the moment ☺

apps not waking the cpu from deep sleep and being more efficient than a super fast cpu running more slowly and performing the tasks for longer. sounds better to me at least thats the idea behind the new job scheduler api in 5.x and greenify thats longer that all the components on the phone have to be operating and creating heat Im not an expert but my 2 cents
53?!?
Thats right, 53 hours, or around there at least. So I am using the original root image from mofo, with Greenify Donation Package installed, so I get auto hibernation, but not the system function hibernation....yet. I may be updating to an Xposed image soon, to unlock those features. I have every app possible except Carbonite Mobile (Auto Pic/Video backup/access) and TextSecure ( 3rd party SMS/MMS) set to auto-hibernate, including my 3rd party email K-9 Mail, I don't use the normal GMail app. With my current combination, normal usage inc. phone calls, texts, (mostly) web browsing or stalking the XDA app, I got a whopping ~53 hours of battery life before I had to charge at 2%. My phone is also my alarm clock. Unfortunately I forgot to take a screen shot, but I will try and duplicate it and take one.

hi guys first of all i apologize for this post not having detailed info such as ss from BBS,GSAM and WLD and will post them later !!
and as always i guess with most battery related problems it happened suddenly and i really mean suddenly the day before yesterday everything was perfectly fine and i didn't have that ridiculous battery drain !!
i woke up yesterday only to find out that Android OS is taking more than 50% of battery usage with a drain like 20% over night
restarted many times and by the end of the day i installed GSAM and WLD (wakelock detector)
froze most of apps including the ones i installed recently but i didn't install that battery hog apps (nothing unusual) and also they didn't appear in partial wakelocks section of BBS
btw i don't use any fake battery extender tools or memory boosters it's just Greenify
i observed that sometimes when i unlock my device (i use knock code btw if that matter!!) wifi gets disconnected and reconnect again (wifi icon disappear and re-appear again in 3 secs or so)
i'll upload ss in a couple of mins
thank you
Edit: SS Added
and notice how it drained 5% in just 40 mins (20 mins SOT) !!!

I had the same problem with battery drain(although not as severe) along with huge data consumption when using a significantly modified(i.e. heavy debloat and ota disabled) rooted stock rom. I tried a few customs roms and dorimanx kernel(not at the same time), and even though battery drain wasn't as bad, they were are waaaay to buggy to be used everyday(especially the dorimanx kernel, it's really bad).
Just last week I tot back to KK and ota updated to the latest LP rom(lost root unfortunately). Then I uninstalled/disabled every app I could/needed. Everything is very fast, smooth, and stable again. I now lose 1-2% every 8hrs in standby with syncing and wifi/data enabled, bluetooth and nfc disabled. I regularly get 5-6hrs sot over 48hrs with moderate use and brightness on auto.
I do have a new battery though - my old one( came with my "refurbished" phone from freedompop) gave me 2-3hrs of sot - but that was when I first got it and before I started modifying anything.

How is dorimanx kernel bad? How many user downloads he has,lots and lots then are we thousands of user wrong using a bad kernel, come on . Maybe it didnt work for you. But out of those thousands of users cant be wrong. If it was that bad no one would download. Just saying , you should just say it didnt work for you.

Just last week I tot back to KK and ota updated to the latest LP rom(lost root unfortunately). Then I uninstalled/disabled every app I could/needed. Everything is very fast, smooth, and stable again. I now lose 1-2% every 8hrs in standby with syncing and wifi/data enabled, bluetooth and nfc disabled. I regularly get 5-6hrs sot over 48hrs with moderate use and brightness on auto.
I do have a new battery though - my old one( came with my "refurbished" phone from freedompop) gave me 2-3hrs of sot - but that was when I first got it and before I started modifying anything.

Can you tell us what app have you uninstalled and disable ?
What have you debloat ?
Thank you very much
My G2 (vs980) has also been suffering from a sudden battery drain. Android OS and Android System seem to be the problem. They are now second and third on the list of battery usage, after the screen. Before now, they were never that high on the list. I noticed this last weekend, when I kdz to the latest update for the vs980, which is 3AA. After noticing this, I flashed the xceed kernel, then cloudy with dorimanx kernel, and the battery drain continued. I even kdz back to kitkat, still the same, then I flashed AICP 11, and still the same battery drain by Android OS and system. Finally, I restored a backup of stock lollipop 39A but, the issue continued so I turned on airplane mode and it seems to help a bit. I still notice battery life isn't the same as before. The os and system still drain more than usual even on airplane mode.
Kind of glad to hear I'm not the only one with this issue. I don't think I need a new battery, since I bought the phone new in April 2015 from Bestbuy.
Also Gsam, shows the temperature of phone between 80°-90°F, where before it would be in the low to mid 70s. One time, it even got up to 104°F, funny thing is, it doesn't even feel that hot in my hand.
Hopefully, we can find out what's causing this because I really liked the battery life on this phone. Even when people complained about the battery life being worse on 5.0.2, I was pretty happy with it. All my previous phones can't compare to the g2. Now I feel like upgrading though lol.

How is dorimanx kernel bad? How many user downloads he has,lots and lots then are we thousands of user wrong using a bad kernel, come on . Maybe it didnt work for you. But out of those thousands of users cant be wrong. If it was that bad no one would download. Just saying , you should just say it didnt work for you.

When I tried the version that was out a month or two ago it wasn't nearly as smooth as stock, even after conservatively messing with the kernel app settings. The worst was that it also cut out tethering and my flashlight when the screen shut off. Maybe the recent updates have fixed some of the issues, but I doubt it. Could be that he doesn't have access to the sprint variant which I have...
Either way, just because 'thousands' of people use it doesn't necessarily mean that it's good - 99.9% of those users have no idea how to code or how a kernel is written. Their knowledge goes as far as following picture guides online - which a 5 years old could do. Just look at the most recent change log - those 'fixes' were to glaringly huge problems that shouldn't have been made in the first place and people were blissfully using it the whole time. Think about how many thousands of other bugs their must be. Not to mention hacking up code made by professionals at huge companies could lead to many other problems. Obliviously the stock kernel has bugs as well, but it works and is fast and stable so I see no need for using a hacked together kernel made by one amateur that doesn't even have my version of the phone to test it on. I wanted it to be good - which Is why I went to the trouble of installing it, but it's definitely NOT.

I uninstalled ALL of the stock apps that can be uninstalled. The ones I disabled are aosp keyboard, app updates, browser, calendar, cloud print, favorite contact widget, google play books, games, movies & tv, newstand, google+, lg voice command speech pack, music, music(the widget - it always runs in the background even without being on the homescreen), notebook, polaris viewer, quicktranslator, swype, talkback, voice command. I would have liked to disable a few more but I'm not rooted so I couldn't.
I use nearly all of the google products like chrome,gmail, calendar, docs, keep, music, photos, news and weather,translate,etc...so having the stock lg ones enabled was redundant. I also only have the bare minimum of installed apps that I need. Nearly all of them are made my major corporations i.e Chase, BofA, ebay, paypal, freedompop, microsoft, swiftkey etc. I have NO games or any small apps that need a ton of permissions. The only small apps are feedly, print hammermill, privacy flashlight(240kb, no ads, no permissions) and bubble level(180kb, no ads, no permissions).
I also go through every settings in every app to make sure it's what I want. And I restart my phone every time I take it off the charger. IMO having a clean and no frills system that is set correctly is the key to performance and battery life.
I just want want to clarify that I average 4-5hrs per 1% in standby since it doesn't seem to hold as well as it gets closer to 0%.
theres this app that have lots of info on battery..
thx guys for adding your experience
i hoped moded kernels would've reduced that amount as they should have necessary drivers for wifi which was somehow got messed up but from your reply i guess i've to look somewhere else
idk how to put this, well this isn't a solution at all i actually didn't start working on it yet just thought to share what i found so far !!
so it's just a reference for any one whose luck was bad enough to have a wakelock like that !
1st of all in most cases neither the device nor it's battery are at fault *you need to understand that*
faulty battery doesn't show up kernel related wakelocks instead they drain without a reason so i hope ppl stop accusing battery in every battery drain thread!
2nd after understanding that you'll have to deal with the environment your phone is used in
to put it simple it's your router and all devices in your current network !! (idk though why not all devices get affected by that or why it just started now, tough luck yea)
those threads may help

http://forum.xda-developers.com/google-nexus-5/help/getting-rid-wlanrxwake-wakelocks-t2519294
what i'll try to do is add an old access point to my router and connect my phone to it as i don't have a replacement router right now!!
i'll let you know if things were improved !
hey guys
i thought to share what i did so far and before i go on there is a bad news and a good news !!
i would start with the bad news first !
-no rom could solve this issue so you don't really need to format everything and start from scratch especially if you didn't mess around too much and you found it started suddenly like here, i've tried couple of roms including latest CM13 build it wasn't that bad but it didn't solve the drain that much either !!
-now some ppl may see this bad and some may don't care (which means good!!) google services are the ones responsible for this drain
well man you didn't come up with anything new and i see you've got a problem getting straight to the point besides you talk too much
i'm sorry
now you have to sacrifice your google services background sync including "GCM" if you are using any services similar to pushbullet or notification mirroring you'd understand why it's important
anyway if you are good with that you may install and yea it works with latest google play services
https://play.google.com/store/apps/details?id=com.playfulgeeks.gservicefix
and do as instructions (and believe it'll work if you did steps right)
if you prefer manual way then you'll need "app ops xposed module" and deactivate every "wake up" permission from google services
this guide may help but remember we don't have tools natively in our roms so don't bother downloading "shortcut maker" and go through your settings app to find "privacy guard" or "app ops" we don't have those natively like them
http://forum.xda-developers.com/oneplus-one/general/guide-google-play-services-battery-t2832525
i'll share some ss from stock battery stats
i'm sorry for my long post and i hope it'll help someone with same issue
idk if it solved issue completely but things are stabilized a lot now and i just lost 1% over night not 20% or 30% like before !!
and i'm using lollipop now so i guess it's not that bad for what i heard about bad lollipop battery since it's my first time trying it !!
and btw real SOT should be +40 mins so the real SOT is 2H-47M cuz i restarted my phone to apply that fix and for some reason battery stats doesn't stick between reboots !!
if anyone interested in trying that rom it's for D800 only btw and thx to @Swetnes for his work rom feels pretty stable and solid :good:

good luck everyone
Hi, so I've had my G2 D800 model for a while (about a year or two), and for the most part, it's been an excellent phone despite being 3 years old now. Never had any slowdown problems, and it's always performed well in games and in general.
But just recently, about a week ago, it just started lagging out and being very, very slow.
For example, if I'm watching a YT video through the app, if I rotate the screen, it takes maybe 5-8 seconds to actually rotate. Also, in a lot of circumstances where the keyboard has to pop up, it just freezes the app until the keyboard pops up maybe 10 seconds later.
It's also just laggier in general in most apps, scrolling through FB or Twitter freezes nearly every second when I'm scrolling. It's generally unresponsive and sometimes just freezes outright. It also acts this way on the homescreen, and in most everything else.
The most annoying part, however, is that sometimes the devices just doesn't turn on for sometimes up to 15 seconds after pushing the power button (and it usually just refuses to turn on when using my knock code).
The odd part, however, is that once it's actually in something like a game, it performs perfectly fine.
I've played a number of Cardboard games, as well as games like Nova 3, and it performs perfectly.
I've also ran multiple benchmarks (Geekbench, 3DMark, etc), and it scores around where it should.
Info about the device:
LG G2 D800
Stock Lollipop 5.0.2
Software Ver. D80030f
Kernel Ver. 3.4.0
Rooted
TWRP Recovery installed
XPosed Lollipop installed
G3 Tweaks installed, a number of tweaks applied
Everything else is stock (homescreen, etc)
What I've tried/checked:
Checked memory usage during "lag sessions", rarely dips below 300mb free
Changing minfree values through Rom Toolbox (tried every preset, as well as setting everything to the max to free as much as possible)
Rebooting (affects nothing)
Checked CPU speed with Rom Toolbox (is at max, and does achieve the max speed of 2265 MHz. Setting it to performance mode/setting the min speed to be 2265 MHz has no effect, but reduces battery time)
Changed default cache sizr (tried every preset from 128kb to 4096kb. With multiple benchmarks, the optimal value for r/w bounced between 512kb and 4096kb, currently on 4096)
Things I have not tried (that I am aware would possibly have an affect):
Changing anything in the kernel tweaks/build.prop
Completely wiping, reformatting, and reinstalling (I really would rather avoid this if possible, as it would take a while to get everything back to what it is now, and it was a pain to upgrade to Lollipop in the first place)
I am unaware of anything else I could try to fix it, which is why I'm here
So, does anyone know of any other solutions or things to try? This has made my phone very unreliable, even for phone calls and messages, which is a problem.
Thank you for your time and help!

Hi,
First thing i need you to try out is this custom kernel : http://forum.xda-developers.com/lg-g2/development/lp-5-0-2-kernel-3-4-107-dorimanx-1-0-lg-t3102512
Then install greenify, and hibernate all the unnecessary apps.
This should solve the issue.

Thanks for the quick reply!
I'll try out greenify, though there aren't many unnecessary apps running (i uninstalled all the bloatware first thing, when I rooted).
And about the custom kernel, it's something I've never tried, so I have a couple questions.
Will it wipe my device, or break TWRP, root, or Xposed? (Sorry, didn't see the answer on that forum)
Will a TWRP backup I make be able to fully restore my device to it's current condition?
Is everything that is supported on my device be supported with that kernel? (Apps, etc. Don't know a whole lot about how kernels work, so I don't know)
Thank you!

Hi,
Even you uninstalled bloatware, the apps you use daily could be running in background and taking all those rams. So whenever you play a game or dont use a certain app, just go to greenify and hibernate. Since you have xposed installed, you can do more than that such as u can stop sync , etc.
About the kernel, it has a ram management settings and cron task.
Ram management dont need to be altered. It has some preset profile so if you seek performance, just choose performance or if u need battery , select battery profile etc.
Cron task is useful because it will do alot of things automatically. For example, it will release ram at certain amount of time from the apps , it will restart google play service since that could be an issue , etc.
All you need to do is take a nandroid backup just to be safe. Then download Dorimanx Ota from playstore and it will detect ur device and show u which version of kernel is available. Then download that, go to recovery, flash it, and you will see three app installed : Synapse -- will give you all the details of ur setup including cpu speed, temp etc for monitoring purposes
Dorimanx settings - this is the main settings of the kernel. You will see a P icon on top, tap it and choose your desired profile.
Color management : It is as the title says, just leave it be.
Then use your device, check your ram and report back. Hopefully it will resolve your issue.
Wow. Dorimanx did a lot more than I was expecting.
Downloaded the app, downloaded the kernel, flashed it no problem, went through and checked out synapse.
Went into the Dorimanx settings, and set it to the "Performance" profile.
Immediate improvement.
The whole phone seems a lot more snappy, and I switched back and forth between a 1080p60 YT video, facebook, and twitter with absolutely no problem.
Free memory when idle (no apps open) stays around 1gb; it used to be about 500mb before.
Tested a few games for the heck of it, and it actually seems to have improved game performance somehow. (It seems to have overclocked my CPU to 2.5ghz, though, so that makes sense.)
Temps stayed at around 58-60c while running a few Cardboard apps, so it seems fine.
Thanks for the help iubjaved! This has fixed my issue and then some! Ah, the wonders of the Android dev community.
