How to get a good battery life!

Well I don't no where to start really as I know I will get told off for making a new thread about battery life!
But this is hopefully some help for people out there that are trying to get a decent ROM and kernel to improve your battery life, well mine has really improved since flashing my Samsung GS2 with Lite'ning ROM 6.1 and flashing the kernel with SpeedMOD T-40.
I have spent lots of hours reading forums about battery life, I think I have tried everything known to man about this phone, somethings worked well somethings didn't, I wanted to get a decent battery life with out sacrificing any features I love about my phone!
When I got into rooting, about 2 months ago I was a n00b, but I stuck to it and learnt a lot each day, it's not easy and you can't expect someone to tell you how to do it, you have to read up about it like everyone else!
But anyway back to why I've created a new thread, well after installing Lite'ning ROM 6.1 at the beginning of the week which I really like as it keeps the Samsung software, I've used TB Pro to freeze the Hubs as I don't use them, the battery life wasn't what I thought, in fact I think I got a better battery life with the stock rom unrooted
I did some researching and found that the kernel can make a difference to (I'm still learning) so after reading some forums I learnt that speedmod kernel worked well with Lite'ning ROM, as It was just the kernel that came with the ROM, ninphetamine 2.0.5, so I flashed the kernel last night with Odin and within minutes I was back up and running.
I then charged the phone 100% and then use a battery calibrator app to wipe battery stats, I then did a basic test which I previously did before, I went to sleep with a fully charged phone, I left everything on: WIFI, mobile data network and sync on set my alarm clock and went to sleep (p.s I checked a few websites so battery actually went down to 98%)
8 hours later I woke up checked my phone to see what % it was left one, previously on stock ROM with same set up my phone would be on 65% due to the Android OS bug running high! This time it was on 91%, so that's less than 1% drain an hour! Happy or what!
I know some people might not say this was a actual battery test but to me it is and I can see a big difference, funny thing is the AOS was showin 35% in batt stats, which is strange!
Now as I write this at 1pm my phone has been on for 14hrs and I'm still at 75%, yes I know the first 8 hrs was in standbye, but I've had a lot of notifications come through from G+ this morning and I'm pretty happy with what I have got set up now, without compromise as well!
I will upload a screen shot later if any wants to see when my battery stats when its down to 1% etc
I hope his helps some people out there, but I wanted to keep it simple for some as I was once a n00b (might still be)

"Want good battery life!!!" - I believe the OP is ordering the reader to demand better battery life. I agree with the OP. Let's start "Occupy Samsung" movement.

thanks for this thread. i will definitely try it later after some playing around with CM7

@Maverik: Np dude.. glad to help
@Kreo: basing in OP's statement and the last part of it, he is stating how to get a better battery life instead of demanding for it..

Op, do you have auto sync on?

No worries, I thought that if it helped me its going to help more ppl.
What's CM7 like, you trying the stable or the nightly?

I am the stable. its snappy and i liked the different look and feel with other roms that i hv tried such as litening, villain, batista and stock.
Today i installed setcpu and will see how the battery will perform.

Cool, I did try CM7 but it was a nightley, build 68 I think, if they had brought the stable version out a week earlier I would be on that now, but I hear there are still bugs?
At least with Lite'ning its completely stable plus I like the look of the neon blue effect
My battery is on 64% now, I think I can go 2 days with this now

I'm on CM 7.1 Stable now and now even after 2 days i still have almost 40% battery left out, though on stock i never got more then 1 days

That's not bad, which Kernel are you using, the default one?
I have 5% left and going to screen shot it at 1% to show ppl what they can get, bearing in mind I could get max 12hrs out of it before!
1 day 9 hrs so far brilliant if you ask me!

I first rooted it with superoneclick and it downloaded odin and flashed some insecure kernel first and then rooted it
Then i just installed CM 7.1 with Rom Manager, not sure which kernel is it

if you are gonna try cm7 try the latest nightly build....thats pretty more stable than the "stable" version...i think build 83 is out today and that will have pretty much more bug fixes and i hope they can get that browser lag fixed and thats pretty done deal for me to switch over to that completely

If you installed with ROM manager that will be the generic one that comes with it, check in about phone its second from bottom.

I can't keep up with the nightleys plus when I tried build 68 I think it was, camera didn't work at all. Is the latest much better?
Also which Android version is it based on?

Happy!
So as promised here are screen shots of my phone running at 1%, I forgot to screen shot CPU spy as well (sorry) but I can say that with this set up I am really happy, as I cannot remember when with general use I have managed to get over a day with out charging my phone, iPhone 4 included!
If there is a better set up out there with a newer ROM I would be interested as this is based on 2.3.4 tho Google Talk video works so I'm happy

man that os is very high....but you still managed to get a day out of it so not bad work buddy..
nightly there is a new one coming out today version 83...still few bugs they need to sort out but once that is done il be on there...that firmware is based on 2.3.7.
im using speedmod latest kernel..it does not support bln or bootlogo but i would sacrifice all that for a decent battery life which i am getting....so far 5 and half hours past and im down to 75% and 2hours screen on time....not bad i think

Android 6.0 Marshmallow battery discussion

This thread is for battery life discussion of android 6 Marshmallow.
I took the plunge recently and installed cm13 nightly on my phone after a couple of days with sultan's cm13 ROM. One notice that the android team really got the battery optimisations right this time especially when coming from android 5.1. The cell standby and android system bug is now gone and the phone can now be in standby for a long time. My usage pattern is browsing, reading in Adobe reader, listening to mucisc with bluetooth headphones, facebook, wassup, some youtube videos, sms and few calls. I play farm heros sometimes but I don't play graphical intensive games.
Here are 2 screenshots of my phone. It was charged to 100% at 8:00am on 30/11/2015 and it still has 41% left as at 10:00am 02/12/2015 Granted I have only used it on wifi and I configured wifi to automatically disable 5 minutes after the screen is off.
You can post you battery life too.

If a moderator deem it fit, he/she can close the thread but I felt it will be nice to make a dedicated thread for Marshmallow instead of looking through a big thread to get the relevant information needed for a particular android version.

yes.

It still sucks on mobile data. Nothing changed from Lollipop in regards of mobile data battery drain and i wish google could do something about it.

That's it! It's still on LP niveau

i had around 2 hours of screen on time and less than a day's battery life. The MMS also didn't work with WiFi connected, so I switched back to CM12.

I finally charged the phone today but not before I took a screenshot. My usage is not heavy at all so for heavy users, I guess the SOT will be longer but the total number of hours the phone was on will be lower. My usage did not change form that of 5.1 but I can definitely see a great change in standby time.

Still doesn't beat out KitKat in terms of heavy usage IMO.

The performance(yield) of the battery essuperior to android 5.1. The cycle of load lasts approximately two hours more of screen.

Try Omniron Herna build, it does wonders on my phone regarding battery usage
Sent from my A0001 using Tapatalk

6.0 has the same battery life as 5.x for me. about 4-5h SoT.
KitKat and early 5.0 builds were clearly better with 8h SoT

Currently running Sultan's ROM CM13:
My battery life has hugely improved when I'm not touching the phone, no one app is draining way to much battery while not in the foreground.
There is one problem some people including me have been experiencing which is that Wi-Fi doesn't switch of properly and drains the battery, the only solution I found was to reboot the device after switching it off.
Not sure if this is a CM problem or the specific rom but not AOSP.
But apart from that battery life is good.

On sultan CM 13 CAF
Getting 4-5 hrs of SOT

Still waiting on a fix for mobile radio active. Had to go back to KitKat after a year on 5.x and a week or so on cm13. The difference in battery is staggering. Here's hoping Google actually finds a solution for the drain, otherwise I'm gonna have to stick to KitKat until I get a new phone.

I dont worry much abt battery charge ..currently on CM13.. dont see much of difference ... expect charge to last for 1 day.. connect to charging when home

Tech guys suggest me best battery rom for OPO don't fun with me by saying cm11s 44s. Almost 1 year stick to cm11 I need some latest android version in my device,
I'm new to xda
Thanks in advance!

Just stole myself this glorious phone yesterday (not really.. got a smokin deal) after 3 years and a month on a Nexus 4 that was left stock the entire time. My OPO is already rooted/unlocked so I'm trying to test out and find the best rom for battery life as both of the cm lollipop and marshmallow roms I've tried are about equal in terms of buttery-ness and just stick with that rom indefinitely.
Is general consensus that cm11 kit kat is far superior to the later cm roms in terms of battery life? Which exact rom would you choose as the last rom you flash onto your OPO ever?

Since the last update my battery became literally two times bigger.
As you can see in the attachements, I have exactly 12 hours of SOT.
I have been all day on WhatsApp,in an Android group and 30 minutes added of calling ( not hd ).
What's your sot on the newest update ?

What settings? Official ROM? Kernel? What app Disable? Root?

June security patch?

Yes just stock ROM stock everything. I have disabled every app that I don't use .

Romanian - ROM CSC latest patch

This is possible if you continuously keep the screen on without doing anything on it. It's what you did too.
Or if it's the other way, seriously, 12 hrs continuously you stared on the screen? (12hr sot in a total of 12.5hours)

well i am getting 3.5-4.5 hr SOT... depends on the wifi vs 4g usage... but usually average 4hrs SOT...

THIS ! exactly this. this is not a real life scenario and im guessing the OP also enabled battery saving mode which means underclocking.
so, stock with disabled apps and only 1 app running and using data and screen continuously on with battery saving on and this is the result, yes it is possible.

I'm more impressed you've managed to stay on your phone for 12 hours out of 12h30min of it actually being turned on...
But to me 12 hours and my phones dead does not seem like a win for me at all.
A stat with 24h on time and around 7-8 sot would be much more impressive.
Anyway the battery is the same as it always has been it's just how you use the phone. (Not security patch)

Speaking of, I haven't received the June OTA yet. Any links to that? I'm on the LUX CSC.

Yes its a nice stat you could probably gain an extra hour+ of SoT from applying a AMOLED friendly black theme/using blacked out apps(facebook,twitter etc) too Only problem is you loose some of the S8 ports beauty...
I'm getting around the same using Ambasadii's S8+ port 5-6 hour SoT but if i theme it black amoled i still have about %30 battery left by the time i go to sleep and put the phone on charge.
Usage is casual ... Xda/whatsapp/facebook/twitter/browser/downloading/PokemonGo

I am unable to find a theme which turns everything black but also preserve S8+ beauty
Terpischora messes up the Notification panel. I cant read anything from Gmail/Whatsapp and also notifications from other apps.
Do you know any good Themes?
Is Ambasadii S8+ Port good? Heating? Bugs? Stable?
I have downloaded Ambasadii Rom havent flashed it lol.
Renovate s8+ port ROM is stable so didnt flash ambasadii yet.
Also I think There wont be anything new in Custom ROMs except Security patches from now on. Development has reached its peak for S7E. Devs migrated to S8+

There the ones i was using.. i aggree the s8ports are kinda at a standstill now only standard bugs like camera faces etc dont get any overheating or battery drain with it seems stable as any other... one of the reason why i swapped it to my primary instead of stock.

Battery life on Oreo

I flashed the stock image and i found the battery life abysmal. Not even a day
7-8 hrs tops with barely any usage
Anyone has experienced the same issue

Give it a few days and see if it improves. Sometimes drastic updates can have adverse effects on the battery
Sent from my Nexus 6P using Tapatalk

I have one of the best battery life on O right now and I'm not pointing fingers to anything but google.
I was excited after hearing "Android Vitals" and they are on point about it.
Try to flash a custom kernel like EX or Flash though Ex's kernel isn't fully committed with the O source code but you may at least try it. On a side note there are still apps out there that aren't coded properly for O which would probably hinder your angler so look out for them a lot.

Thank you everyone for pitching in
Like I mentioned I flashed the stock image and gave it 2 days but as I disconnect the phone from the charger at around 9 AM (100%) , by 3-4 PM I am being left with 30% or less . By 6 PM it starts beeping as it hovers 15%
I barely use the phone at work. I just do occasional messaging (text and whatsapp). I removed all apps except the ones that I really need. No games...etc
I did flash the other day the EX Kernel ( Beta for O) for which I have the paid manager version.
It drives me crazy as it seems to be draining at a very fast rate with no apparent reason.
What's even more frustrating is that the built in battery app doesn't shed much light. The process that takes the most battery is "System" but that's all.
Maybe it's time for a new phone

Yes, I went back to paranoid nougat, because I got the same
battery experience as you with O. But I'm reading that you use
what's app, do you can play a video if someone sending you one? Since the O previews for me the videos are just loading but not playing, and that's only the case by using android O, doesn't matter if I use what's app or what's app beta.

I got the 2% battery drain bug and sometimes i dont, ive reflashed oreo about 8 times lol, sometimes it dies at 15%..

Edit: check latest Pixeldust rom, it's like pa with a bit more useful features

I think my phone may be defective
Even on Paranoid the battery seems bad
The miscellaneous was on top of the list . What does that mean .... ?

Battery update.- Running kylo kernel r9 , working great so far just a few personal tweaks applied.

I'm not sure what you're expecting, give the rom some time and charges to settle battery. How old is your phone? If you don't have patience flash stock image and completely wipe your phone if you think something is faulty.

Well...
I used to get like a day out of the phone . With my minimal usage I would disconnect it in the morning and still have like 30-40% when getting back home in the evening.
All of the sudden one day I was just on my way home and I noticed the phone was off. I tried power it back on but it kept on flashing red as it was totally drained. Since then battery went downhill.
I'm not crazy and I do not have unrealistic expectations but 5 or 6 hours of battery with almost no usage seems a bit off. I gauged just by looking at the numbers being something ridiculous like 10% an hour.
I did wipe and flash the stock few times. Oreo then Nougat
Since the issue persisted I am thinking the phone just went bad.

If your battery is faulty, then it's faulty, that's why i asked how old your phone is. Ain't there battery health apps to take a look how worse it is.

Yeah I think it's maybe 1yr and half old.
I'm starting to evaluate those Essentials and Pixels 2.
Or better get a Pixel 1st gen if they drop low enough

Sounds to me like your battery is worn out. I'm amazed that you got 1.5 years out of it because I've seen posts from people who didn't even make it a year. You mentioned that it's draining 2% at a time and shuts down at 15%, which are pretty strong indicators that your battery is shot.

Nokia 8 (pure android) is an option too, but I would change the battery, n6p is still a very nice piece of hardware. Essential
is a hype phone til now.

Hard to say, I will run accubattery for week, after a first charge it doesn't look very promising for me too, and my phone is a bit over a year old. may some other users know a better tool or app, but this one doesn't seem to be so bad. Let's see what happens after some charges.
Akku Gesundheit=Accu Health, sry it's german here.
If you search for a replacement there is a thread here on xda
for the 6p, OEM battery or something like this

Bad battery life / new OP8Pro / 5-6h SOT / Tips?

Hi y'all,
bought my first OnePlus ever a week ago but I get like 5 hours of Screen On Time, while I saw here on xda people getting even 10 hours with 120 Hz.
Running latest stock ROM, not rooted because I actually don't need root.
FHD+ 120Hz, no AOD.
Factory reset done, Wipe Cache done.
I'm not gaming, using my phone for Chrome, WhatsApp and Social Media (not 24/7).
Any tips for me?
I kinda do like the phone and may keep it, but I hate to say that my 3 years old P20 Pro still gets 6-8h SOT. I know, display is better on 8Pro but still...
I dont have a problem installing custom ROM and custom Kernel if that's gonna get me towards those 8+ hours SOT.
If installing custom ROM, I still need my banking apps working/safe, if that's maybe not the case.
Thanks!

Stay on latest OOS, root and use a custom kernel

But with root my Banking Apps may not work right? Paypal/Crypto/etc. may not work or be safe either or?
I already tried debugging with GSAM Battery Monitor and noticed that Google Play Services wakes the device pretty often but somehow doesnt use much % Power. Google Play Services has also the highest Sensor Time of all apps.
Any tips on that one?
And also, which Kernel? Bluspark?

Turn auto brightness off if on; then set brightness low.... See if it helps.

I don't use auto brightness and I use brightness at like 35-45%. So that shouldn't be an issue either. Thanks for the tip though.

I also just got the 8 pro and am noticing battery drain. What kernel do you recommend?

Hi y'all,
bought my first OnePlus ever a week ago but I get like 5 hours of Screen On Time, while I saw here on xda people getting even 10 hours with 120 Hz.
Running latest stock ROM, not rooted because I actually don't need root.
FHD+ 120Hz, no AOD.
Factory reset done, Wipe Cache done.

Just got the 8 Pro also ... brand new. Noticing battery drain as well. I lost 10 % overnight. Are you seeing similar drain?

It will take few days to settle up but still, with stock OOS it was bad.
I flashed LineageOS + Magisk + Radioactive Kernel and I am still testing it out but it doesnt seem to be much better than stock. Maybe a bit but no way of reaching 8 hours SOT.
I'd suggest try something else and report here, so I can test it out too.
I was thinking of testing PixelExperience and/or Stock rooted OOS with custom Kernel but I'll give a LineageOS a chance 2-3 days more.

Thanks. I just installed Omega Kernel and that seems to have made a slight difference.
Do you use AccuBattery by chance? My estimated capacity is 3855 mAh ~ design capacity is reading correct @ 4510 mAh. Not sure how accurate this is, but it would mean that the battery isn't what it should be or received a used device / defective battery?

Nope, I dont use AccuBattery. Tbh I think it cant read the value correctly.
I actually flashed Havoc Rom 2 hours ago, no custom kernel. Ill check how it's gonna be.

How can you flash Havoc | Custom Roms without TWRP? Where can I find Havoc? I didn't see in the custom ROMS / Kernels section.

How's Havoc battery life after a day? I added Naptime and am using the Magisk Module GMS Doze. My overnight drain dropped from 10% to 7%, which is still way too high. I am using xXx No Limits as well.

I haven't set my phone fully yet because i wanted to try the Rom out. I have now "only" Facebook, Instagram, WhatsApp, Discord and few smaller apps logged in but that's it. I don't know about standby drain but I'm now at 51% battery with 4hours screen on which means it's better but still no chance of reaching 10 hours. 7 hours should be reachable right now

Uninstall or at least disable apps you don't use.
