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.

The OS isn't always the reason for battery drain, many factors take into play.
How often you use the device.
Applications like widgets, email push.
Wi-Fi. If your not on it shut it down it else is always going to try to find a signal and drain battery.
Bluetooth. same with this.
Using the net.
Things like Google now, it's always running and trying to update info, shut it off of make intervals longer.
These are just some things to take into account, but at all use the phone different, and im not saying the OS doesn't drain but it solely isn't the only reason.
Hope this help.

I'm having the same issue. I read that the media drain could be caused by bad media files, but I didn't have any issues before this weird.
In my experience when you first update to a new samsung rom, the media using the battery is your phone updating the picasa albums...which stinks because it also eats your data like crazy if you are not on wifi and forget to turn off sync until wifi is available.
I've noticed faster than normal battery drain as well on my device. Normally by 4:30pm I'd be at 40-50%. Now I'm in the 20-30% range.
I'm going to try factory defaulting it soon and run it for a day or two. OR I might not even do that and just go directly to Task's AOKP or CM10.

Before everyone jumps ship, may want to try a new kernel. KT and a few others should work on the new release. Just make sure you choose one that works on JB TW and not ASOP.

It's seem the culprit is the android.process.media.
Each time i bootup,android.process.media is running for about 30 min, non-stop.
I already do a factory reset+sd formatting, but no succes.
With startup manager, i can block that process,but you need to be rooted .
I use the same settings as before i did'nt upgrade yet..i got it fully charge with no texting and calls the next 1hr its already 80%..i think i would try to cycle first my battery for 2 more days..then i'll see if it still have heavy drains..thanks for the response guyss.
Check out my overnight drian! from 1:30 to 10 the average drain is around 4% an hour, Losing about 20% overnight doing nothing.

I just got this phone the other day and immediately updated to jelly bean.Though I have nothing to compare it to my battery drain seems normal. I'm losing about 5% an hour but that is with some use (it's new so I'm playing with it a lot).
I did notice more drain the first day of use (may have been because I was using it a lot) and noticed maps was taking up quite a bit of the battery and I wasn't using it. So I uninstalled the updates for Maps and then re installed it. Battery drain seemed much better after that and now the maps app doesn't even show up in the battery report(before it was about 3rd and it seems kinda high on yours as well though you may be using it).
i'm noticing about the same battery consumption as the stock ICS rom. about 1~2% per hour when idle and sitting, 2~5% per hour listening to music over bluetooth with the screen off, and 5~10% per hour surfing the net and watching videos and stuff.
Well after doing probably 5 resets on my phone , it seems like everything is working fine . I was having issues with the battery drain ,internet not connecting, and phone calls taking 2 minutes to connect.
I was having issues with high battery usage as well after updating to JB.
I froze most every app and widget associated with AT&T and Samsung (with the exception of AllShare) and flashed KT747 kernel and set governor to ktoonservative (default settings).
I am really never a heavy user during the day, but with the same usage I had on ICS, I average 15.5 hours (with the phone at approx 15% when I shut it off to charge) - screen on time between 2.5 and 3 hours; call time between 45 min and 1.5 hrs; media (which seems to be a big battery hog) only about 6 minutes. I use bluetooth exclusively, so that radio is on all the time the phone is on. I keep sync and background data on, but only turn mobile data on as needed.
I had been getting some higher battery drain with JB than I was with ICS, both were on rooted stock ATT roms. Early on I had posted that it was about the same as ICS, but after more and more use, I was starting to find that it really wasn't. I was consuming about 5-8% per hour idle and 10+ while actually using it. The idle bothered me the most because, obviously, using a phone will drain the battery
Two things have stood out as the high consumers: Media Scanner and poor signal.
To address the media scan drain, there have been suggestions to change CWM settings to backup as .tar rather than default .dup. This ONLY works if you re-do each nandroid that was a .dup as a .tar, delete the .dup backups, and clear the unused backup data through CWM. This removes the blobs folder files which will be in the thousands.
To address the poor signal drain, I flashed the UCLH9 modem (see modems thread in the development forum). Better Battery Stats is not showing any drain caused by poor signal, and this is also reflected by actual usage, the signal is simply... better.
Consumption is marginally higher than on ICS but not nearly as high as I was experiencing. If this has already been covered, my apologies for eating up server space...
Could you alternatively put a .nomedia file into the clockworkmod folder on the device? Would that prevent it from scanning that folder?
Well I'm bone stock and not rooted, I have no backups and the media is eating my battery like mad since the update. I've killed the process several times but it starts back up on its own. The only way I know to fix it will require root.

There is a rogue app in the stock TW that is doing it. I have seen it in every 4.1.2 port. Run a de-bloat and it will go away.
Do you know what bloat exactly is causing it?

I have all the att and Samsung bloat frozen via TiBu.
Trust me, something is there. I never had the chance to figure out exactly which app it was though. I have a feeling that it may have something to do with a Samsung app.
I would suggest using OS Monitor from the Play Store. Make it show all system processes and see if you can dig deeper into it.
Edit: Also, here is my humble opinion too. People keep wanting new and better features. Well, that always comes at a cost. Just remember that. The iPhone boys are learning that the hard way too.

I agree with that sentiment... I'm considering reverting back to ICS but the smoothness of jelly beans is too enticing.
after making these changes yesterday I got a 40% battery consumption over 9 hours with average use which IMHO is plenty.
Solution is to reboot the phone OR unmount by going into settings, storage and unmount the USB there instead of from the notification bar. I think this solution works but have not tried it myself.
rebooting whenever the os gets out of hand, or unmounting the SD card, is not a viable option IMHO.
my post was directed toward root users who have cwm installed and are experiencing the media drain because of the blob files. the modem change I tried because all the reliable jelly bean ports seem to use the H9 modem. a weak mobile signal is detrimental to battery life, as is a weak or intermittent WiFi signal.
believe me, on my rooted phone, these two changes made a real and noticeable improvement in battery life in JB. I've gone half the day today on ICS and half the day on JB. battery consumption is now within the range I had on ICS.
one the one hand, I believe that some increase in consumption is due to the "omg I has the jelly beans and I'm going to use the bejeasus out of my phone" factor. I also believe that a good number of fixes and patches are simply a placebo effect. BUT, my phone had been getting hot and tearing up the battery due to signal searching in areas where it had been fine prior to the update. heck, we have an att tower within 100 ft if my office, I typically pull 69-70mbps at work. on the k3 modem I was regularly dropping data or losing LTE. not anymore.
Un mounting then re mounting seems to have worked for me the process can now be killed!

the last4 hours the phone was on my nightstand unplugged doinga sleep drain test. 0.3% per hour.
Ok I have found something running on my SGS3 that wasn't running all the time before and now its open constantly. I need to know if anyone knows if this one is safe to FC and then disable.

I'd like to see that list too if you don't mind sharing the info
I think I'm going to do a factory reset soon. Pretty sure that these drains are caused by some leftovers from ICS...
I've been having some strange battery issues.
TLDR: Phone battery drains and warms up when in use, but not when in sleep. Resetting batterystats doesn't fix it. Closing all processes doesn't fix it. It does it on a bunch of ROMs, which were always clean installed. The usual battery saving tricks do nothing.
More detailed:
Basically, whenever I use my S3, I get a considerable amount of battery drain. I used to have fantastic battery life when I was running LiquidSmooth RC5, where I was capable of 4-6 hours of screen time in a day. Now I can only get 2 or less hours of screen time in a single charge. This seemed to start after flashing LiquidSmooth RC8, but I also have the same issue in LiquidSmooth RC9, LiquidSmooth 4.2 beta, Task & Ktoonsez 4.1, Task & Ktoonsez 4.2, Slimbean, and Cynagenmod 10/10.1. So I don't think it is my ROM.
Anyways, so the battery drain only seems to happen when the phone is in use. During that time, the bottom of the phone around where the CPU is located gets considerably warm after just a few minutes of use. Otherwise, when the phone is locked, it deepsleeps fine with no drain. It still does it even when I go through my entire process list (and cached process list) and stop everything, it doesn't help. I've tried the whole batterystats reset where I charged to 100, drained, then charged to 100. That didn't help. I do make sure to clean install my ROMS, including clearing user data, cache, dalvik cache, and formatting my /system. When I look at my battery usage, it usually seems to be Android System using my battery the most. It can also be Android OS, Google Services, and Media sometimes. I've tried a ton of fixes, nothing helps. And of course it still does it with WiFi, data, GPS and all that off.
Help would be appreciated
battery life is an issue with many different factors.. there can be a bad app, bad battery, bad rom, anything really. if your phone is having issues then maybe 4.2 isn't the best for your phone there are many different roms to choose from and many are very stable.
Running 4.2 isn't the issue, though. It does it on 4.1 ROMs too. I'm not even on a 4.2 ROM right now.
Sounds like a rogue app or widget draining it. Get better battery stats. Type it in xda search. That will tell you for sure what exactly is draining the battery. Good luck.
Maybe your battery is just shot and its time for a new one

Hi,
I follow the forums here for years but have not posted yet, hence not allowed to post on the dev forum in the appropriate thread, had to open a new one
A couple of days ago I installed "[ROM][JB][4.3.1][JLS36I] CyanogenMod 10.2 Alpha (Build 3)" on my wife's phone. Until then she was still using the stock GingerBread ROM. The phone got so slow to the point of not being usable at all.
After I flashed to CM 10.2 it feels like a new phone. Lightning fast, good looks, everything works - fantastic, very much appreciated and thank you very much @ Devs!!! :good::good::good:
One big problem though:
When running the stock ROM the battery usually lasted about 2 days. Now, with CM10.2 it is empty after half a day. Since I did a full wipe before she is using less Apps as compared to before and there is no single big consumer. Just the typical mail apps, facebook etc.
When I look at the wakelocks there is one app consuming most CPU which is CSipSimple. But that app was also running before the upgrade when the battery lasted 2 days.
The screen seems to consume more power though, is that possible? Anyone else with similar experiences?
Thank you very much!

You can try out battery calibration app before new kernel. Cause there is no "wipe battery stats" on cwm 6.0.4.4. I had same problem, and its a bit effected on cm 10.2. It's free. Maybe it will solve your problem.
Battery Calibration
That sounds very good, let me try that!
I have the same issue with increased battery drain. Yet I've not been able to identify the source. I disabled a lot of services (with Disable Service), also deactivated unnecessary system apps.
Cell standby is also shown as a huge drainer, although I usually have a good signal and no losses (checked with Better Battery Stats). There are no wake locks out of the ordinary.
Now I'll try battery calibration to see if that helps at least some amount.
Actually for me nothing really helped.
I eventually identified the 3 apps that drained the battery via Wakelock detector.
Those apps are Facebook, GMX Mail (based on K9 mailer) and CSipCimple.
Before the update to 4.3 my wifes phone was running the stock gingerbread and did not have an issue at all with those apps.
Yet on CM4.3 they are draining the battery.
Once I uninstalled the apps the batter life is back to normal. Which is sad, because she needs those apps. But no other solution so far from my side....

You can try out battery calibration app before new kernel. Cause there is no "wipe battery stats" on cwm 6.0.4.4. I had same problem, and its a bit effected on cm 10.2. It's free. Maybe it will solve your problem.
Battery Calibration

Again the myth with whiping battery stats / battery calibration. Make a full charge and unplug the charger. This will whipe your battery stats.
And for the ones who never get this. The stats are just some data about apps consumption collected while the battery gets discharged. The ROMs are whiping them by itself on each full charge and after shuting down the phone.
This data has no Infulence to how long a battery lasts. It´s just collected to show you visually the statistics.

Thanks ... yeah well did not really expect it, but when you're desperate
At least I thought it helps with the effect that the first 50% of the battery last 3 times as long as the last 50%, but not even that changed

Hi,
One big problem though:
When running the stock ROM the battery usually lasted about 2 days. Now, with CM10.2 it is empty after half a day. Since I did a full wipe before she is using less Apps as compared to before and there is no single big consumer. Just the typical mail apps, facebook etc.
When I look at the wakelocks there is one app consuming most CPU which is CSipSimple. But that app was also running before the upgrade when the battery lasted 2 days.
The screen seems to consume more power though, is that possible? Anyone else with similar experiences?
Thank you very much!

I had the same problem with my S4 running CM 10.2 stable. The battery was empty after 8 hours. What I did was to change the theme, and today i got 12 hours and only 20% of the battery gone and wi-fi/3g all the time. Well, I still have only one hour of screen up time, but that is how it was before... I don't know, i'm just saying! Maybe it helps. The theme i added is LunarUi 2.
All the best!
Hi Guys,
i have a bit of a problem with the battery in my GNex maguro.
I'm an avid Rom flasher, but when i have something that works well i usually settle with it for a while. So i flashed Cataclysm (http://forum.xda-developers.com/showthread.php?t=1995801) sometime in the last months and it was running great. Best bettery life i had so far.
Then with the release of Android 4.4 i looked for a rom to test it. I flashed XP (http://forum.xda-developers.com/showthread.php?t=2539201) and i really like the 4.4 changes.
But since then my battery won't even last a day in standby mode. I thought maybe it's an issue with 4.4. still, but even after flashing back to Cataclysm (newest release) i still had the same issues. I thought it may well be, that the final version isn't what it used to be, so i flashed another rom again. This time Purity (http://forum.xda-developers.com/showthread.php?t=2012706) aaaand... still the same problem. So now i'm pretty much lost. I also tried different kernels (lean kernel specifically) but to no avail.
My battery used to last 2+ days in idle mode. Now i can see my battery drop every minute. It barely holds over 10 hours. I already did a full phone wipe and flashed back to stock before installing cataclysm again but still no improvement.
I hope someone can help me here or point in the right direction.
Sorry if this topic already exists, but the search funtion doesn't seem to work right now and google didn't show something helpfull.
Thank you all in advance.
I don't know why you would still have bad battery life moving back to the original rom you used but.. on 4.4 it is most likely the new Google Now features that constantly listen for voice commands. Disable it by long pressing on an empty part of the home screen and go to settings. Slide Google Now Off and go to voice and turn off hotword detection as well.
I get great standby battery life on 4.4. I'm running the 11/29 ART build of cmetal(toro), 150ish hours of uptime without any issues so far.
Re: Bad Battery Life since KK
What kernel are you running? Are you just using whatever kernels come with each ROM?
I'll try turning off google now and the voice stuff and report back.
It still seems really weird to me, that the problem still persists after flashing back to 4.3. My guess would be, that 4.4 flashes something hidden that messes with the battery. But i don't know where or what.
Especially since it persists after a complete wipe (/data, /system and /cache).
Well, i'll see how it behaves without google now.

Well i used mostly lean Kernel with 4.3 roms but i can't find any 4.4 kerneles besides CM. I have XP installed right know which uses CM Kernel.
Re:Bad Battery
Make sure your governor is set to interactive or ondemand...it could be seeing power drain from being set to one of the performance settings.
It's also possible that your battery is just going bad...do you have a backup battery you can try?

It could just be that you need to replace your battery. They are only good for so many charges and do degrade.

Reporting back. After deactivating google now yesterday my battery is still ****. It's at 50% after 2h idle and 30 minutes screentime. Before the 4.4 flash it would be at around ~85-90% now. I suspect that 4.4 flashes something in some hidden partition that i don't have access to, that messes with the battery. Users on other boards report the same issues as i have.

Just checked. Governor is set to interactive. It's also the default setting.
I sadly don't have a backup battery.

Could be, of course. But it's kinda weird that the decline is so dramatic and it has to be a pretty big coincidence that it just happend after a 4.4 flash. Seems unlikely to me.
edit: I'll order a new battery just to eliminate the battery as the source of error.
Mine is pretty bad but it's running google play to death so maybe gapps flash was bad? dunno

sorry for my bad english

Same problem here. Since I flashed Kitkat on my phone, battery life isn't enough to last a day on standby. I tried installing another kernel (ASKP) but to no avail. Please keep in mind that I'm not very experienced with custom roms and rooting my phone. Does anyone have some good tips to improve battery life?
Update: After fiddling around a bit with better battery stats, greenify and a bunch of other stuff... i still don't have a solution. I made some screenshots of my stats, but can't post them here because i don't have permission to do that...
So i reflashed swordrune's cm11 rom and it seems to be working better with 1080p kernel w/o art enabled. i'm 11 hrs in with 80% battery on the extended battery (toro btw)

are u sure greenify didnt helping??? already got rooted & exposed installer running??
can u state your screen on time??
usually gnex can handle 3-4 hour screen on depend on battery condition n phone performance... not include idle n stanby time.

that will help.
if u lightweight user, i suggest u to optimized performance. use apps such trickster mod, rom toolbox, or in addition of any light battery saving apps ( for optimization)
should be improve on screen time.

Not to hijack your thread, but I'm also experiencing battery issues after flashing the XP 4.4 rom. I did enjoy it but the battery drain was terrible. Not only that, for some reason my charger drains on a 1A charger but charges slowly on a .7A somehow. I only have 1 micro usb cable so I can't test if it's the cable and I can't find any apps to check the current speed. I tried downgrading and flashing to Slimbean but so far it's been no dice.

Ok, back again. hibernated every app and system-app that was running in background. Still wasn't getting better. I then saw the only services still running are google location services. I deactivated them now to see if these are causing it.
The biggest wakelocks i have are "wlan_rx_wake" which seem to be a known problem with KK:
http://forum.xda-developers.com/showthread.php?t=2519294
I then researched again and found several threads in google groups which describe the same problems that i have. Across several devices (though mostly Nexus 4, 5 and 7).
Google seems to be aware of that issue and is working on it.

Yes, same for me. Charging is really slow since 4.4 as is the bootprocess of my phone. From the first vibrate when switching the phone on it takes ~10 seconds until the google logo pops up.
i dont know any about gapps issues bcoz not running any gapps in my phone since last year.
1. try searching for updated radio.img (baseband/ radio) if got any network issue.
2. try install trickster mod app. this app can help you for tweaking into deep sleep, also help for optimizing.

Hmm I don't know if this is going to resolve the charging problem but i will try it and also try and use a battery calibrater and come back.
