Cyanogenmod 10.1 terrible battery life

I have recently installed cyanogenmod 10.1 onto my galaxy s3. The battery life since then has been very poor. If I leave my phone on without even using it, it drains about 1% every couple of minutes. When I look at the battery it says that the process of "phone" is taking up a huge amount of battery. Can anyone tell me why this is or how I can fix it?

Generally these issues are user related and not ROM related.
I was so frustrated with some of the ROMs when I first started out but then realized I was doing a few things wrong (mainly because these ROMs, including CM10 have very decent battery life).
First, I would recommend a clean reflash:
factory wipe / reset
wipe cache (some say twice)
wipe dalvik cache
install ROM
after rom loads, wait 5 minutes (don't touch at all) then reboot
now you must wait.. sometimes it takes 24 hrs or so for a ROM to correctly load.
Not sure how true it is, but some say to now drain battery down, then fully charge.
At any rate, I follow these steps all the time and works great!
Also, keep in mind that most of battery issues are user related.. so think about what settings, apps and kernels are being used on your end before question a ROM. This is why waiting 24 hours or so before installing all of our "crap" will give give the ROM more time to settle.
Hope this help!!!! Happy Flashing

Thanks for the reply. However, I have looked at what apps and processes are draining my battery. And it appears it is the "phone" process that is doing this.

Just to piggyback on spenny88's reply, exactly what did you come from (stock?) and how did you wipe and flash?
This is all key as to how well your device will perform.

I have noticed something similar. I am coming from stock. I am going to guess my battery life is in the neighborhood of 10% less. I wiped everything before I installed CM. That said, this feels so much faster than stock.

Having the same issue with my Samsung Galaxy Tab P1000 (p1 in Cyanogenmod). "Cell Standby" is taking as much juice as "Screen", and I am using Wifi only. I don't even have a sim card in the device. Wish there was a way to disable Mobile Networks without disabling Wifi via Airplane Mode.
I installed through Rom Manager as upgrade from CyanogenMod 9.1 with wipe. I will try the recommendations above and report back.

Try the latest nightly (or RC4) of CM10.1. The battery life has definitely improved a bit.

Samsung Galaxy s3 intl battery drain cm10.1
I recently installed cm10.1 nightly on my international S3, it has cut the battery life down drastically and seems to drain over 10% an hour, even when not being used.
I've tried everything that i've came across by searching and still haven't had any real gain on battery life. Doing a full wipe and reinstalling doesn't help, and i've given it time for battery to calibrate; no difference. Even with wi-fi and location services off i'm getting a big drain. I've even tried switching to Slim Bean, if anything the battery was worse still.
Firstly i'm getting that Android OS is eating up a large chunk (usually above 60%) and using BetteryBatteryStats i don't see anything out of the ordinary in terms of partial and/or kernel wakelocks. I really don't wanna have to put the stock Touchwiz rom back on but that seems like the ways it's going. Any help would be greatly appreciated. Is there anything else i can try?

i find i get terrrible battery life on AOSP when i restore google through the setup. i skip thru the installation and open the play store to enter my gmail. then, before restoring my apps, i let it charge to 100%. honestly AOSP still doesnt have decent battery life, but it does improve if you play with it and try different things

I would respectfully disagree with you. I have run a number of ASOP based ROMs and find them better than stock in terms of battery life. Certainly better in terms of not making my eye bleed (as I hate touchwiz, but that is a personal preference). I find that SlimBean gets me the best battery life of the CM based ROMs.
To clarify, I get just over 1%/hour battery drain, when idle (as measured by BBS) with GPS and google sync enabled, mostly on LTE. My phone happily spends almost all the time I am not actively using it in deep sleep.
The recipe to achieve this is to disable google location reporting and history, avoid tons of widgets that constantly update themselves, disable samsung services that you do not use, and monitor battery usage to look out for rogue apps that do stupid thengs, like hold wakelocks when they should be idle. Dropping the minimum frequency to 192 MHz, and going to ASSWAX (CPU scheduler) and ROW (I/O scheduler) also helps.
To get decent performance you do need to install things properly. Which means ensuring that you don't have conflicting settings or random leftovers. I tend to dirty flash updates but you reallly do get better and more consistent performance going through the pain of a complete clean install (format system, clear cache, reload apps from the store) when you are switching ROMs. Only use TiBu to restore app data. Once you do this, in my experience rogue wakelocks are the biggest cause of lousy bettery perfromance, and you can track down and eliminate these. I have around 150 apps loaded and do not run any task manager/autokiller. My phone typically runs without any reboots or power cycles between ROM updates which equates to rebooting every couple of weeks to a month. I have seen over 2 months of uptime.
Certainly should be able to go 16-20 hours between charges which I would consider real world all day functionality. I guess my point is that rock solid stability and all day battery life is possible if you are systematic about how you do things.

I have the same problem..... Battery lose 1 % every 2 mins thats terible. :crying:
How could i find a fix ? plz if u have fix yours tell me ???

What do you do to reduce your Tab S power drain?

I have a SM-T800 on CM12.1 that averages a current drain of around 60 mA during deep sleep. I also have a OnePlus One that averages around 9 mA during deep sleep.
I'm using Battery Monitor Widget Pro with the "Android mA" setting to get my readings on the SM-T800.
Obviously, there's quite a difference there. The SM-T800 draws almost 7x as much current while it's doing nothing - no screen on time.
It makes me think that there must be something I can do to reduce the current drain, especially with a rooted device. But, I haven't been able to figure out what.
Has anyone been successful getting their battery drain lower? If "yes", what have you done?
Thanks,.

Did you forget the thread you made 2 weeks ago.
http://forum.xda-developers.com/galaxy-tab-s/help/sm-t800-barry-drain-t3157867
John.

Yeah, @Tinderbox (UK), but since the title was messed up I didn't think folks were looking/responding/searching to the older thread.
I think this is still something we can all benefit from, if someone has figured out a way to get our power consumption down. And if someone does respond back to this thread, other folks will be able to find it when they search now.

I use Euphoria OS and debloat it, that gives me a few weeks of standby if it's just sitting on a shelf. Ensure you delete Trebuchet (replace with Nova/Apex/etc) as it sucks a huge amount of CPU power when idle.
If you can run without GApps you'll maximize the savings.

As i said last time my T800 only used 1-2% in 16hours what ma does that work out too, the battery is 7900mah
7900mah/100 =79/16*2=9.8mah
Every time you install an app, it can make an huge difference, if it stops your tablet from sleeping.
You need to check your wakelocks to see which apps are keeping your tablet from going into deep sleep, auto check for emails, sync, alarms will cause your tablet to come out of deep sleep.
John

Thanks, @Tinderbox (UK).
As a test, I decided to wipe out my current installation, and just load the latest Nvertigo SM-T800 ROM and the very minimal nano Open GApps. I had to load a few minor things beyond that to get functional (KeePass Droid, Opera, MyBackup Pro, Wakelock Detector). I disabled all Google account sync items.
I disabled Trebuchet wake-ups, and set autostart off (Thanks, @fraser.dk)
I'm still seeing about 1% drop every 4-5 hours.
Nothing stood out from Wakelock detector. After 24 hours of the tablet sitting idle, the wakelocks were all less than 30 each.
Are you running a specific ROM or Kernel?

I am on the Stock UK v4.4.2 kitkat rom, I have never flashed though i am rooted.
If you are rooted, try the app in the link below, it link to XDA and you can download a version of cpu spy reloaded, it works great at spotting wakelocks it`s the only wakelock detector i use now.
I am running an Sony App that is supposed to stop all wakelocks, it`s in standby mode, you can whitelist apps if you like, I am not certain if it`s doing anything at the moment, you need root and exposed installed.
http://www.xda-developers.com/optimize-battery-life-with-this-useful-app/
A 1% drop over 5-6 hours is not bad.
John.

So i have an result on the Sony Battery App, I put my Tab S into sleep mode at approx 12:30AM it was at 69% , I woke it up at 6:50pm, it was still on 69% after 17hrs.
Click the link below, to see an screenshot of GSam Battery Monitor.

for me i have downgraded back to stock kitkat 4.4.2, debloated, rooted and xposed installed, and use powernap, i can use the tablet all day and still have between 45% - 60% battery left depends on if i am playing games or not... i have tried so many apps and custom roms in lolipop and none of them have good battery life....

PowerNap which is the Sony app i use, only reduce battery drain in sleep mode, by stopping all wakelocks, it does not reduce the power that games or other high drain app require, so how does you battery last longer, how much power were you loosing overnight when you tablet should have been sleeping it must have been immense.

on kitkat i had no major battery drain, i just like having powernap on my device... on LP like i say even just using the tab battery would drain like 1% every min... just doing typical web use... i have tried everything to get good battery life on LP but nothing works for me at least.. but with KK i have no issues...

A lot of people say they have had no problems with lollipop, but there is an significant number that have reported problems after upgrading, I decided to stick with kitkat and await android m.
1% a minute just browsing that`s bad.

I think I'll try going back to KitKat, and see how things go.
I have been frustrated on how fast the battery drains when doing minimal tasks, like reading an ebook (about 1% drain a minute).

Bummer.
I installed the Canadian stock KK ROM (T800XXU1ANJ6_T800XAC1ANI1_HOME.tar.md5) onto my US SM-T800, and it's boot-looping.
I thought I should be able to load the Canadian version without any problem.
Is there a way to turn the tablet off when it is bootlooping? I don't want the battery to drain while I'm downloading another ROM.

Try this to stop boot loop.

What do you do to prevent OTA updates? I have TWRP installed via the All-in-One Auto Root.

If you are rooted you will not get ota updates, if you are not freeze the updater an tab s owner did that with an app called "package disabler" it works without root but the free version keeps being removed from google play store, the full version is £2 (£1.50) just reduce.

@Tinderbox (UK) WHAT KITKAT ROM YOU ARE USING ????

stock UK kitkat rom v4.4.2, Lollipop has been out for my T800 10.5" for an couple of months, but it is full of bugs, and quite a few people have went back to kitkat.
Kitkat has been solid for me, I ran it for 164 days continually, I never rebooted or shutdown in that whole time, no problem at all.

Getting very bad battery life on Nougat

Hello Everyone,
So from last week I have tried 5-6 different nougat ROMs (OSS Open beta 9/10, Official RR, RR by Eliminator)
am getting very bad battery drain like 18% per hour while phone idle. Also, Phone is warm to touch.
I tried to switch back to ext4 format that didn't help.
Also, I have no apps installed, no sim card, I did use SuperSU 2.79 with OSS.
I formatted data partition before installing every ROM
But somehow with EmotionOS I am getting good battery life and only 0.29% battery drain while idle.
Edit: I'm getting same results with CM13.

1. It is still a known issue. OnePlus will release a newer update (v4.0.2) the following week.
2. Of course, it wouldn't help. The only thing that F2FS has an advantage over EXT4 is slightly better read and write speeds (if I'm not wrong).
3. Use stable SuperSU v2.79 only. SR1 and SR2 are known to be battery drainers. Even though, they are not the real cause for it.
4. Some users it help and for some it didn't.
P.S. continue using EmotionOS or Freedom OS (I currently use) to get good battery life for now.

That's correct. I have my current ROM (Freedom OS v2.1.1 - based on OOS v4.0.1) and I have 5-6 hours of SOT.
It's worse than (Freedom OS v1.7 - based on OOS v3.2.8) which I had 6-7 hours of SOT.
But, let him decide the right ROM for him (no offense though). Maybe he wanted to test them all, I don't know.
Nougat is not very stable at all right now. I'm waiting for OOS v4.0.2 the following week. I hope it fixes 95% of the problems users experience.

Clean install and see if the issue persists without any apps installed.

You guys that do not do clean installs are the ones that generally have problems from old residual data that can cause a variety of issues. However, if you do a clean install, you will find that many of these problems go away. It helps to use the roms the way they were designed and used in the lab. I always wipe everything and do a totally clean install and I had never had these problems.

Frustrating Battery Situation. Let's figure it out! help??

I never had a good battery on this phone since I bought it (second hand)
my average SoT is about 2hrs for around 15h uptime daily
I formatted many times trying to fix it, changed roms, kernels, governors, interactive profiles. nothing worked
I thought it was the battery. so I changed it by myself and it's the same, or even worse than before (lol)
Yesterday I removed my google account to see if I have too many services running. and still have 25% active drain and 3% idle (ex kernel manager stats). too much
I don't know what to do now.
1) someone suggested me to watch wakelocks but I need help on that because I don't know how exactly and what look for
2) do you think that could actually be the device? is it possible that lg could accept it as defective? I don't think so. they should be able to repeat my issue, and we know that isn't possible since battery usage is very personal
3) do you have any configuration you suggest me to try.....? maybe I'm missing something
Thank you for your attention, I hope that this thread will be useful for everyone

Personally, that's just about right for me. I think I get about the same SOT if I had light usage. Usually though I get 3-3.5 hours SOT with around 12 hours off the charger. I top off for an hour on the charger once a day everyday and just got used to it. A lot of times if people have longer​ uptimes, doze was working overnight​.

Have you tried to flash it back to the stock nexus image? (Return it entirely to stock) That would be my first step in nailing down battery issues. It will completely wipe your device, but it rebuilds all the partitions and updates everything to the newest images. (Assuming you've downloaded the newest release from google). Then you can run it on pure stock for a few days and monitor it. My n5x isn't the greatest either with battery, and standby drain is brutal on nougat no matter how you configure it, but I usually get at least 4 hours of sot. It also depends what you have running. If you're using bluetooth and location services, google assistant ect, it follows the battery is going to drain much quicker. If you flash the stock image, you need adb and fastboot installed. There's lots of guides here on XDA.

@throcker, my advice: try a ROM, stock or PureNexusc, clean flashed, without GApps, any Sync off, GPS and mob data off. You should get 5-7h SOT.

3hrs would be great! but my drain is too much definitely

Have you tried to flash it back to the stock nexus image? (Return it entirely to stock) That would be my first step in nailing down battery issues. It will completely wipe your device, but it rebuilds all the partitions and updates everything to the newest images. (Assuming you've downloaded the newest release from google). Then you can run it on pure stock for a few days and monitor it. My n5x isn't the greatest either with battery, and standby drain is brutal on nougat no matter how you configure it, but I usually get at least 4 hours of sot. It also depends what you have running. If you're using bluetooth and location services, google assistant ect, it follows the battery is going to drain much quicker. If you flash the stock image, you need adb and fastboot installed. There's lots of guides here on XDA.

I wiped completely several times, downgrading to 6.0, updating via ota, flashing lastest image, with and without encryption
I use bluetooth (g watch)
I'm very experienced on flashing and stuff, tried everything by myself, this thread is a desperate thing

@throcker, my advice: try a ROM, stock or PureNexusc, clean flashed, without GApps, any Sync off, GPS and mob data off. You should get 5-7h SOT.

tried that too....
You all wanna know what's going on now?
battery 23%
Google play services 18%
whatsapp 11%
screen 10% (1,12h)
and I don't even have google account.

@throcker: GPlay-services means, you flashed GApps. They are busy in the background without account.

I'm sure you can hit 3 hours. Just don't expect 15 hours off the charger.

That's an extreme exception. You're on the far right side of the bell curve in battery life. I bet I can't even let YouTube play for 8 hours straight to get that kind of SOT. LOL

Damn! What ROM/Kernel/Settings/Apps/etc?

@crazyates: PureNexus, Franco (stock), no GApps

What features do you lose by doing this? I'm assuming you can't install apps, but can I still sync my contacts/gmail with my google account?

@crazyates: l sync contacts&calendar with PC by MyPhoneExplorer and mail with mailserver. Free apps from GPlay by apk-downloaders.com.

oh $#!T.
but...I'm really bounded with google services stuff, I sync my pc chrome, keep, docs, maps....
I think I'll give this a try, but there is no way I could run that setup as my daily.....

Same here and I don't really know what to do... Really frustrating and I don't even have BT, NFC and GPS toggled on!

Use BettetBatteryStats to check for wakelocks during the night to see if something is keeping the phone awake. Then I also recommend either unplugging the phone from the charger right before going to bed or setting a custom reference point to check how much the phone drains during idle. I had the problem that my phone was draining about 2.5%/h in idle even with nothing installed, airplane mode, everything off and so on. This turned out to be a hardware problem which could only be fixed by replacing the motherboard. So check if you have the same symptoms that I did.

Question High battery consumption on idle

My phone is usually on idle and not used due to my job. But Im noticing extreme battery consumption even when Im not using it. Never had this issue with other phones. Last night I checked the batter before sleep and it was at 67% at 1 AM, today its 62% at 7 AM so there must be an issue because it should only drain 1 or 2 percents during idle.
In battery settings the top app using the battery is phone idle.
Im on xiaomi.eu 12.5.6 rom but I had the same issue with stop 12.5.3 so I dont think it's because of rom.
I had great battery life with my last phone which was poco x3 nfc with the same settings and apps so it's not because of any third party apps either.
Anyone else experiencing the same problem?

With AOSP ROMs, I even had worst experience when I installed one of the custom kernels because they somehow didn't put the phone into deep doze correctly. But yeah, the idle consumption is quite high - even on stock Kernel.
Currently I use HavocOS and its stock Kernel - and SuperFreeze (from F-Droid store) to freeze most apps right after screen lock. Idle consumption has dropped to 0.1-0.2%/h as a result. I made a thread some days ago regarding this topic... see here.

Thanks. Im gonna try your guide but it's not the most noob friendly guide I've seen
Just Kidding, thanks for your time.

Oh, my thread wasn't meant to be a guide... I did put it in "Question" like you did, but a mod seems to have moved the thread to "General"
My "solution" is only temporary - at least I hope there are still developers out there who value a low idle drain more than fast charging and benchmark numbers...

Sorry for the OT, could it be that the app. is called SuperFreezZ?
Have you noticed any good battery life gains with this app.?

Yeah, sorry, SuperFreezZ: https://f-droid.org/en/packages/superfreeze.tool.android/
For several months I had the problem that from a certain moment, the consumption at idle suddenly increased enormously (from 0.1-0.2 % to 2-3% per hour). Even if I manually forced all apps to stop, In Android's battery info "Android OS" and "Android System" showed up with double-digit percentages. I could only get the phone back to its previous behavior with a restart.
To date, however, it is not clear to me what triggered this. I suspected GCam for a while, then Osmand+, but I couldn't ever confirm that because the problem didn't start whenever I used those programs, just sometimes.
I never found a real solution for this, but SuperFreezZ did.

The best thing I've used for years now is Greenify, its hasn't received an update in more than a year but still works perfectly

Do we need root to use these apps? I remember using greenify before onmy older devices with root but havent used it for a while. Gonna see how much it drops tonight and then try to tweek some things and recheck it tomorrow night.
Weird thing is, I was getting an awesome battery life out of poco x3 nfc, could it be because of the cpu idle? Because that's the only thing that seems different between the 2 devices. (X3 even had an lcd which is supposedly less battery friendly)

Unfortunately, hardly anyone notices this because most users do exactly what the F3 was designed for: Playing games.
I came from a 2.5 years old F1 and it lasts easily longer than the F3 although it has a smaller battery and a LCD screen... The F3 behaves anything but fully developed. These latest high-end SOCs (870, 888) are really powerful, but unfortunately not equally power-efficient. That's the reason why I throttled the CPU and undervolted the GPU. This dropped the active drain from ~8 %/h to <5 %/h on my device and my usecases.

Yeah. I used to underclock the cpu on my old phones but I dont know about undervolting. wouldnt it cause issues? I just used 3c toolbox app to set a lower max clock and a lower min clock for cpu cores. I read somewhere that rooting xiaomi.eu rom breaks some functions so I havent rooted it yet. do you have any info on that?

As long you don't push too hard with undervolting, it works quite well. See attached image (it's not mine, but I have oriented to it).

Konabess doesn't need root, afaik. Extract the boot.img of your ROM and copy it into a folder of your device. Then use Konabess to modify the settings and repack it into a modified boot.img. This file you can flash with TWRP. No guarantee that it works for xiaomi.eu, but it works for AOSP (at least it worked for me).

I'm ont he same rom as you and let me explain my experience.
My battery has been insanely good. Even with heavy usage over a period of 4 hours, which included 1.5hrs of SoT and pandora playing though bluetooth all 4 of those hours with dolby and viper enabled. Was at 100 and dropped down to 94%. So It may be an app or setting that you have installed causing problems and draining battery. The only battery saver addition I have installed is Universal GMS doze. Idle time for me It takes me about 5 hours to drop down 1%.

Well if there is an app that is causing this, it should be shown in the battery settings. But the only thing that is eating up my battery is phone idle. So it might be a service or something. Im out of options right now unless I find a way to root this rom without facing new problems.... Worst thing with miui is that you cant do things like rooting as easy as other roms.
Btw, would you please tell me the settings and xiaomi.eu version you are on? Im on 12.5.6 stable and using 120hz + vivid color scheme and most of my apps are on blcok background activity except my messaging app. And Im losing battery on phone idle not the screen on time!
Ss below.(dropped from 92 to 82 woh only 30mins screen on time doing nothing but checking xda!) And 7hrs of those 9hrs I was asleep and the phone was on airplane mode + gps off!

You could try BBS or similar apps. Maybe it's an app which prevents the phone to go to deep doze (wakelocks).
BTW: MIUI sucks

I switch my screen refresh rate down to 60hz but since your phone is idle it really shouldn't come into play unless you have always on display or turn screen on for notifications.
Rooting this phone is amazingly easy. Takes like 5mins if that. My Mi 9 lite took longer to root then this phone.
As far as an app draining battery, It more then likely not it since you saying phone idle, which in the past people have said if you phone has problems with signal this can drain a battery. For me this has been a major issue. With AT&T service I would loose double the amount of battery over night (I play pandora through out the night when sleeping). Also if you have apps that are heavy internet usage (unsure where you at but things like facebook and messenger drain tons and yet don't register battery drain on most analytics. And since you using a xiaomi.eu rom I know alot of those bg services are disabled or removed.

Yeah thanks for the info. I used to root my devices easily by flashing magisk but it seems they have changed the method, though I found the method on a post on xiaomi.eu website and rooted my device.
Tried to lower cpu frequencies a little and use superfreez app. It seems better now but not as good as what you say...
Gonna play with settings a little bit more and wait for another xiaomi.eu stable update to see if it's a bug on this version.

Someone made a auto script for it, but you will have to reflash rom and factory reset data. You really shouldn't have to change cpu feqs. Also uploading a screenshot of my last 2 hours. I know its only 21min of SoT but also 2 hours off charger but playing pandora as well as some other app usage but still at 100%

Ah, ok... I thought you could load a separate boot.img - my fault, sorry!
Then you've to have root for Konabess...

Just to show what's possible with HavocOS 4.9 and 12.5.6 EEA firmware, see atached screenshot... It's with the stock kernel of HavocOS, but with the modifications I did mention here.
Running for almost 2 days
~8 hrs SOT (2 hrs of which with 120 Hz and 2 hrs of which with 100 % brightness, otherwise 60 Hz and brightness between 25 and 50 %) and still 50 % battery left.
