I've been searching the forums and around the internet for fixes on this, but I can't seem to find one. My phone has been working fine until recently where my phone is draining extremely fast and running hot. I was on cleanrom 2.1 and I check the battery and the android system is always on top around 55 percent. I restored back to stock rooted and the android system is still around 35 percent. Any suggestions to fix this problem?
I am having the same problem, using stock rooted ROM (I have not installed the current OTA update).
It just started in the last day or two. My phone is burning through the battery in about 7 hours, under circumstances where a couple days ago it would have lasted 3 times that long.
I am seeing Android System at 90% of battery use.
More data:
My S3 has been unplugged from charger for 3h 35min. Android System is at 88%. CPU total 3h 32m, CPU foreground 5 sec, Stay awake 3h 29m.
I also have a Galaxy Note which has been unplugged for 4h 9min. Android System is at 3%. CPU total 33sec, CPU foreground 7sec, Stay awake 6m 4sec.
So, something has the S3 CPU cranking essentially all the time, together with Stay Awake, which it should just be a small fraction of the time.
Any advice on rectifying this much appreciated!
Start by downloading better battery stats from the play store (if you don't want to donate the $3 to dev, xda members can download a free apk of the same app in the main app section on the site here). Set it up by enabling root access in the settings, then it will need to some time to gather some stats (hour or two). The app has alot of options so dig through the 2 top menus to locate the culprits.
Start there

I'll try that. I just installed GSam Battery Monitor a few minutes ago and it shows Number of Wake Locks: 1005 in less than 4 hours since it was unplugged. That's got to be way way too many, right??
You definitely have something keeping your phone awake and running the processor. Not familiar with GSam, but post back with your findings. Screen shots will help of graph displays
My phone is now getting extremely hot, the android system is down to 20 percent, but the media is over 30. I'm trying to install the apk but getting scared to since this phone is running so hot right now
better battery stats hasn't showed anything after around 25 min but gsam showed around 500 wakelocks in 25 min?
I would wipe system and reflash what ever rom you want. Unless you Odin actual stock rom nothing is wiped. Actual stock image flashes image over partition which basically does same as wipe. Root66 is no different than running any rom. Must wipe system before restoring to Root66.

Here is the BetterBatteryStats file. It looks like the culprit is the SDM process which is the OTA updater from what I understand. I have frozen it which others say should fix the wakelock issue; hopefully it will kill the nag to take the OTA as well!
second day now after full charge, "android os" is using most of battery around 30 percent. deleted_wake_locks seems to be using the most battery followed by bam_dmux_wakelock
30% is normal for Android os

Alright cool. System and media are down now. Not sure what the problems were. Everything is running good except battery is still a little hotter than normal.
Looked around don't think android os should be at 30. Battery still draining fast and phone getting hot after a couple minutes of slight use

Are you not near a 4G tower, perhaps? The phone might be trying to keep hold of a weak signal.

hey im a noob here so im sorry if this has been asked before but right now i upgraded my phone to ics and the battery life is horrible and im too cheap to get a battery extender so is there anything i can do to improve it or am i just going to have to deal with it?
Get your phone to 100% battery and then just play whatever you like until it completely dies. Then, plug it in to charge and dont touch it until it gets back up to 100%. That is supposed to increase the battery lasting time by 20%. It only works once...so dont do it 5 times hoping for results. This is supposed to be done when you first get the phone, but if its never been you've never done it, its worth the shot.

Let the ROM 'soak' in. It'll get better. You are probably busy messing with it figuring out all the features which is normal and makes the battery seem terrible. But overall it is pretty good.
And the post above is an old wives tale these days. It's funny to read people still recommending it.

Kinda, when you first flash with a factory reset, you don't have a battery stats file. This is another good reason to flash when your battery is 100% charged. When Senior Members here say "soak in", they are saying that the first boot all of the system apk (application packages) are cached to /cache. Doing too much while these apps are being cached screws up the statistics of the battery stats. If I really want good battery life, I totally wipe, and let the phone sit for 10-15 minutes. I leave usb plugged in till it's 100%, then pull the usb and use the phone until it totally dies.
By this time, the day is over and it needs to be charged anyways. I plug it into the charger before bed and let it charge up all the way with nothing running (no wifi, no bt, no background apps running).
After that charge, battery life seems soo much better. ymmv. it would be good to know if that works for you too.
Otherwise, everyone uses their phone differently, and some people install stupid apps that have intensive background services running that eat batteries, then complain about the rom sucking instead of introspecting about how they use their phone.

Just to clarify - battery stats file have nothing to do with battery performance and the battery stat file "is reset every time you unplug from power with a relatively full charge (thus why the battery usage UI data resets at that point)." Google Engineer Dianne Hackborn
ahh ok thanks guys ill do what you guys said and see if it helps
you can also install one of the battery saver apps on the market, like juice defender or similar. They will typically help and some can control how often background services are allowed to collect data.

These arent as helpful as they use to be. I have seen and challenged people to run with and without and the added battery life is either very minimal or actually worse with these apps.
Battery saver apps where created when android was very young and had bad management of the battery power. The way it works now it should lower the power to the radios low enough to save battery but not completely shut off the radios. Shutting them off will actually harm battery life because it takes so much more power to turn them on and off repeatedly then to let them idle.
no i think it was more designed for froyo and gb because if you try those battery savers in froyo or gb you can see it works and battery last long but if you test it in ics or jb (i have test juice defender with jb in the sgs3) and what i can see its that sometimes it lags (not always just when you like two or three apps open which for me in the sgs3 was weird) and data sometimes hangs i mean it doesn't load pages

Ill agree with you on froyo but gingerbread towards the end was much better.
The biggest thing is people dont realize how much power is used to start and stop things. Letting them idle will use battery but not nearly as much if you start and stop many times a day. Now at night if you want to turn off those things then yeah go for it. But if you are a frequent phone checker then starting and stopping them everytime will chew through the battery.
A good example is this, its summertime go outside and look at your electric meter when the ac first turns on. It will spin reeal fast for a minute or so while the system gets everything going then it will slow down. This same thing applies to your phone and its radios. Each time you shut it off it has to go through a process so you dont get corrupted data. And when you turn it on it has to use a lot of battery to make sure things dont get messed up and get to the proper operating form.
So any app that shuts off the radios manually and such will end up costing you battery if you are a power user.

I put FAH-Q kernal on AOKP and it seemed to help a bit. I was using systempanel and it said facebook was sucking cpu at night while the phone was resting... so i took off facebook for the moment to see if any other apps/processes could be causing a drain.
side note:
I spend 15-20 min in the morning going through stuff on my phone. Then I will listen to music in the car on my way to work 35 min. My phone will be at 80% by the time i walk in to work. I check things during the work day once and a while and by 2pm I will be around 40%. leaving work I will have 35-30% .... ok i'll just quit now and say running 12hrs i will have about 15% left. I think I am an average phone user. not sure how much everyone else uses theirs.

Music soaks up a lot of battery as well as display, data, and sync. You can try turning off sync and data when you don't need them. But it sounds like you are doing better. I am still concerned with what else you have running in the background though... however, 12-16 hours isn't bad at all...

Yes, as well as /system/ and at least .android_secure on your microSD
I would recommend against fully discharging your battery as a matter of course. While this might have been useful in the days of NiCads, deep discharges and heat are the Kryptonite of LiIon batteries.
I have stock android Non rooted. I turned off Google now, reduced the number of apps that automatically sync. Put display down to 15 percent brightness.
I have no idea whats causing this:
Down to 70 percent so far today.

It's obviously the screen doing most of the damage. How bright is your phone set to again? Just 15? I can see the dips when your screen is on and for an hour of screen on time, that's not out of the question on a device that only totes about 5 hours max of screen on time.
Also why are your fonts so huge? Accessibility settings? If you're not rooted and running stock you need to be checking background processes. Id recommend maube looking into rooting and installimg a custom kernel so you can check and adjust a cpu governer to make sure your CPU isn't running faster than it needs to. You could also possibly stand to undervolt a bit.
Edit: made some errors my bad

Speculations until we see a BetterBatteryStats log. Get us one of those if you want real answers. Using the device while gathering the data for the log can obscure the issue, so gather a log overnight. That awake time is troubling.

Yes there were a few apps that had a lot of time, the keyboard, Box.com app, facebook, and a few others. But I didn't bother with it too much because the idle time isnt that bad. The battery goes down quickly two ways: 1. Screen on time. 2. Me checking it every few minutes wakes everything up I guess and lowers it really fast.
What do you mean by "some Youtube"? 15 mins or an hour?
And did you check the Mediaserver runtime? I had a battery issue with my Nexus 5 on stock ROM too and the reason was the permanent Mediaserver activity.
Sadly, I couldn't figure out the reason. Maybe there is a corrupt file on your storage and it keeps scanning or an app is not really compatible with 4.4...
I switched to a custom ROM and the problem was gone...

Rooted -- Calkulin's Stock "Battery Saver" ROM -- Xposed Framework -- a few mods from XBlast Tools running.
First off, a Root Explorer search for com.android.systemui returned nothing.
What is com.android.systemui? I don't think I saw this in my usage until a couple of days ago.
Why does 31 seconds of CPU and 1 second of keep awake = almost TRIPLE the battery use of 12 minutes of screen-on time?????

It's the actual System User Interface. So most likely a combination of the rom and xposed are causing this. Also, dirty flashes of ROMs can cause this.
If you installed a new xposed module and noticed a battery drain the uninstall that module. Otherwise remove other xposed modules. You could always try a frew full wipe in recovery as well.
I have had this issue with mostly with dirty flashing which is my queue to do a clean flash. It's also possible if you restored any apps with data, like from Titanium Backup, could potentially cause this as well.

you got caught up in a lie, with buzzwords that are pushing for you to use the rom. theres no such thing as a battery saving rom. all those scripts/mods being used in the rom are just buzzwords. battery life is all dependent on how you personally use your device, how you set up your device, and your data/phone signal quality. a rom will not save you battery.

Which battery graph? You mean the current usage graph I showed in the OP, from Battery Monitor Widget?
Re Bluetooth: I just leave it on, so when I step in the car it just connects to the car. No muss, no fuss, no bother.
I suppose I could try turning it off and see how much battery I save. I know with my previous phone (EVO4G) the point at which I started leaving the bluetooth on all the time didn't change my battery life to any noticeable extent.
Here's battery monitor widget current use. The EVO idled at 70 - 95 ma. This one does seem to draw a lot more at idle. I don't know what's "normal."

If your phone is vibrating a lot and you have extra UI elements installed this seems normal.
When you only use a small percentage of the full battery smaller drains appear large.

Thanks for the push. Found a nifty WiFi file transfer app this morning. Boy, is that slick!
Hey guys, my Nexus's been overheating lately, but not in a "conventional" way (ex. some process eating the CPU or wakelock madness). I am running the latest official PA build and franco r63 from about two/three weeks, using ART runtime, Veu theme (if that's any important) and everything's been running butter smooth, always, no battery problems (I solved my wakelock problems with google play services blocking some services I didn't need like wearable stuff a week ago).
Yesterday while in my pocket, the phone got hot. There was no process in the background or wakelock eating the CPU so that was downright wierd. The problem is it keeps doing this. It may not overheat always but the battery runs out lightning fast: this morning, for example, I used it for a while (10 minutes) and the battery went down to 90%. I kept it from 9AM to 11:30AM in my pocket doing absolutely nothing, all apps closed, wifi and data connection off, I pull it out and bam 68% and 39 degrees celsius. What should I do? This thing's driving me nuts, and I don't think it's hardware related (at first I thought the battery was dying, but having sailfish os in dual boot I used that for another couple hours and the battery went down by 3%) and it's not even a software upgrade thing, I'm keeping the same exact kernel and rom from a week now with no reflashes.
first off 39C isnt even close to overheating. your body temp averages around 37C, so its nearly your body temp. which is extremely normal! your phone is allowed to reach 105C cpu temp(and 60C battery temp), which it then will shut itself off, to cool off. water will boil at 100C at sea level. so you might have issues, bit they most certainly are not issues with "overheating".
---------- Post added at 05:56 PM ---------- Previous post was at 05:50 PM ----------
it can be anything. can be your choice of apps, can be your choice of rom and kernel(could be your setup). it can very much be your network signal quality(phone and data). if you are very worried about it, or just cant figure it out, i would flash the factory img and just start over.

it can be anything. can be your choice of apps, can be your choice of rom and kernel(could be your setup). it can very much be your network signal quality(phone and data). if you are very worried about it, or just cant figure it out, i would flash the factory img and just start over.

I meant overheating compared to the usual 30-32 degrees I have when using the phone, and the network signal quality is always the same, as the setup and the apps. That's why i am perplexed..

you cant say 30-32 degrees is the norm. the temp outside is not the exact same temp every day. that will affect your phones temp(it cant be cooler than the air around it ). the temp in your pocket will affect it as well. a few seconds after turning on the screen will affect its temp. there are so many variables when it comes to your phone temp. heck, keeping it in a tighter pocket one day, will affect its temp. signal quality will variate as well, in the same places you always are. let alone being in a different location. anyways, 39C is so normal that you cant say anything about that temp. have you explored your wakelocks? maybe you have a stuck process somewhere. that can happen, and will drain battery.

Hey guys, my Nexus's been overheating lately, but not in a "conventional" way (ex. some process eating the CPU or wakelock madness). I am running the latest official PA build and franco r63 from about two/three weeks, using ART runtime, Veu theme (if that's any important) and everything's been running butter smooth, always, no battery problems (I solved my wakelock problems with google play services blocking some services I didn't need like wearable stuff a week ago).
Yesterday while in my pocket, the phone got hot. There was no process in the background or wakelock eating the CPU so that was downright wierd. The problem is it keeps doing this. It may not overheat always but the battery runs out lightning fast: this morning, for example, I used it for a while (10 minutes) and the battery went down to 90%. I kept it from 9AM to 11:30AM in my pocket doing absolutely nothing, all apps closed, wifi and data connection off, I pull it out and bam 68% and 39 degrees celsius. What should I do? This thing's driving me nuts, and I don't think it's hardware related (at first I thought the battery was dying, but having sailfish os in dual boot I used that for another couple hours and the battery went down by 3%) and it's not even a software upgrade thing, I'm keeping the same exact kernel and rom from a week now with no reflashes.

Are you undervolting?
If not, I see a factory image and data wipe in your future.

Wait a minute your a dev and can't figure this out? Most of the issues are common logic, do a clean flash stick with stock kernel and see if the problem persists, if not try another kernel and see if anything changes. If you need to under clock or undervolt since, it can be a plethora of things making your phone get hot.
Does anyone else have the issue where android system is consuming 35+% of the battery? Looking at the stats it seems like one of the bundled services is keeping the radio on for 14/18hrs its been on.
Have the same isssue
Yeah, I'm having this issue too. Android System is consuming HUGE amounts of battery for me.
Thought I was the only one but glad that's not true! Still got good battery stats with the android system drain nonetheless.
Charged mine to full last night right before hitting the sack.
Woke up 7½ hours later and it had consumed 33% of the battery just sitting doing nothing bar getting email & polling (presumably) for Facebook updates.
And that was with Power Saving enabled. Bit disappointing, hoping when I disable auto-sync that it'll kill the drain.
There's lots of services running under Android Systems disable the ones u don't use, I have disabled some got better battery life, still testing some others...
The hardware on the phone is great, but touchwhiz drives me up the wall. I'll be happy if and when we get anything AOSP based, CM being the holy grail. Nice to know I'm not the only one getting this battery drain. I've disabled pretty much everything that's able to be disabled, as all I use is google services.
Same problem here.... Huge Android System battery drains.
I've played around with several things, and as of yet I haven't gotten it to stop other than turning off WiFi. Anyone found a fix?
Mine's more a combo of Android System and Google Services... both take up a majority of my usage... Services typically being a bit more.
Why are there two android systems? wtf...
Is there any way to reduce cell standby?

Same sh*t here. Went to bed last night fully charged, and 7-8 hours later, wake up with 23% of my battery gone.
I'm starting to wonder if moving away from the Nexus line was a mistake. I started running again and the N6 was just too big to lug along with me, on arm or in a waste band, so I decided to try Samsung.
Just got my S6 and I noticed this right away. Last charge I had 2:42 of SOT and "Android Systems" used 47% of the battery. I was just watching Netflix and YouTube mostly. My overnight drain is also quite high, about 1% every 30-40 minutes of standby.
Is that normal for most S6 owners?
To all:
Turn off VoLTE, turn off WiFi calling, install CPU Spy, ensure your phone is going into deep sleep. If it isn't, flash the stock recovery with Flashify, wipe the cache with it, then flash TWRP back with Flashify.
Post your results.

Is this only for people who already flashed TWRP? I'm stock rooted and seeing this.

This is for everyone. If you haven't flash TWRP, then simply wipe the cache with stock recovery.
I just assumed most people would have TWRP flashed, my bad.
I am guessing that that this is an Android problem as the Galaxy S6 Edge has the same problem with battery drains.

I'm not rooted and I don't plan on doing so. I'm not sure of any other options. I unplugged it last night an let it sleep. Android system used about 14% of the battery. And I lost 20% charge. Cpu run time was 38 minutes too. and I never even woke it up post unplugging it.
I believe this Battery Drain Issue is a Lollipop issue. Was haing it with my One Plus One, I fixed it by going into privacy Guard, and going to Google Play Services and not allowing it to stay awake, and start by itself.
Ill find the actual thread and post it, same issues happening with a lot of phones using lollipop
Battery drain on a new device = bad flash (very common on android devices, first run)
1 wipe the devices and start it again from factory problem should go away. (at least the excessive drain anyway)
2 Ensure you have updated the Samsung Services app (this was responsible for most if not all battery drain issues if you reset your device)
3. Turn the bloody Screen brightness down and turn off Adaptive display (way way way too much battery drain using them)
4. LTE off and Cell data off if you on wifi, your wasting battery power communicating with cell sites you arnt using, the weaker the signal the more power you will drain for no benefit
6. GPS / Loc data off unless you need it even then wifi / AGPS is usually more than accurate, remember GPS + poor sky visibility = more power used to get a loc.
5 NEVER measure battery life for the first 24 hours way too much stuff syncing and updating to measure with any accuracy.
I get a solid 2 days out of the S6 with mixed use and a screen on time of 2:30 could get that upto 3 hours but i have a hearthstone addiction
As mentioned above, I highly recommend wiping the cache, even when not rooted.
Also, worst comes to worse, i'd completely redo the phone from scratch via the Smart Switch software samsung provide.
