Battery is dying at fast rate

For the past 3 days my battery is dropping at an incredibly fast rate. Even if its idle it will drop about 20 % every half hour with little to no use. I rooted my phone and am now running fresh with kings kernel but no change. I an even dropping in airplane mode. What can it be? I left it at 90% connected to wifi with the sync off and when I woke up 6 hours later it was at 20%. Any solutions?

Sounds like mine, just turning on the screen drops the batter 1-2%.

Hit menu and click on settings. From there, go to About Phone and then to Battery. Note the awake time and turn the screen off for thirty seconds or so. Turn the screen back on and check the awake time again. If it's not within five to ten seconds of the time you noted before you turned the screen off, something is keeping your phone awake, which does a number on the battery.

square parts or system panel might give a better idea of what specifically is draining your battery, or preventing it from sleeping correctly.

It seems fine, about 15 seconds difference. The weird thing is this only started happening about 3 days ago, I rooted yesterday, and its still doing it.

Go for what Fachadick said. Download and install Spare Parts from the Android Market. Go to Battery History and click on the dropdown box where it says "other usage" and click on "partial wake usage". If anything is taking up one of those bars, that's your problem.
If there's nothing notable there, it could be damn near any of your applications. When you root, you lose settings for you apps (depending on how you rooted), so your autosyncs could be going crazy. Might wanna check those.

What he said Rooting won't fix battery issues. Rooting and installing a new ROM is just like reinstalling your OS. It can fix things or not depending on how it is configured. Likewise it won't fix your phone if hardware is bad.
does it drop steadily or just the first 5-10% or so? There is a well documented issue where the trickle charge stops at 100% and then shuts off so the phone actually drains a bit before it kicks in again. When you first unplug it, the reading may drop quickly until it reaches the real level.
Likewise depending on what you have installed and how it is set up, there may be something keeping your phone from sleeping. Check for partial wake use like the previous poster said and that will tell you what process/application is keeping your phone awake and draining battery.

i had this same problem about the battery before i rooted my phone. after i rooted it i got overclock widget and i get through the day with so much more battery left. i make sure my battery is full right before i go to bed, i put it on airplane mode and go to bed wake up around 7 a.m.(my battery is always at 98 when i get up in the morning so 2% in about 8 hrs) and i get home around 8:30 and my battery is at 48%. and no i dont leave it lying around with the screen off. i constantly go on, text, internet etc.
hope it works for you too!
your friend.

I am having this same problem and it started about 2 days ago. I downloaded Spare parts and looked up the partial usage (screenshots attached). I'm not sure what I'm suppose to determine from this. Mail is showing with more fill-in than any other program, when I click on it, I get the details. Can someone help?

It doesn't appear (to me anyway) that you're having any issues with partial wake time. You may have a runaway app draining your battery and cpu - system panel is invaluable for hunting those down. It will show you each running process with exacly how much cpu it's used. It gets even better and gives evenmore detail if you let it monitor your system over time.

There I go, letting my prejudices get ahead of me again, sorry about that. I think in the market it’s called systempanel – one word.

So will the free version pinpoint the problem, or would I need to do the paid version?

to be honest, I'm not sure - I don't remember what kind of detail it gives you in the free version, but the app is so useful to monitor cpu and battery, as well as for hunting down rougue apps, I would recommend the paid version as a "required" app for all rooters.
when you load it up, the default screen is essentially a taskkiller - but more importantly, you can go into settings and have it show ALL processes, and if you select one of the apps or processes from that main screen, it tells you when it was started, how much cpu it used, how much memory its used, and at least in the paid version, a historical graph of cpu usage - so you can see exactly when it used the cpu over the past 2 hours, 8 hours, 1 day, 3 days, or over the past week.

Me Too - "Android System" extremely high - Stock 2.2
This is also happening to me from 4 days ago. I haven't installed any new apps in the last 15 days or so, and for good measure, i uninstalled the last 10 apps i installed before that. When i check battery usage, the "Android System" takes up between 60 and 70 percent. When i open it, it lists like this:
HTC Checkin Service
Settings
Upgrade Setup
Rosie Utility
Android System
Setup
Accounts & Sync
HTC Widget Download Manager

Bluetooth is off, 4g is off (when's cincinnati going live already!??! Just the heart of downtown and the mall)
Wifi is off, and I've been turning off gps now, but i always used to leave it on and made it through the day.
"Cell Standby" is next with 8%, everything else below that.
I kill everything with task manager now and it doesn't seem to help at all.
It is not possible to exaggerate how fast the battery is being drained. It drops by 1-2% each 45 seconds or so. I've done the Charge-for-8-hours-turn-off-charge-trickle-charge-unplug-trickle-charge-unplug-etc thing last night and no help. This is with no widgets installed, no live wallpaper, no music, when for months i can make it through the day with a little pandora, bluetooth while driving, a game or two, internet, maps, and several other apps throughout the day. I've stopped everything but messaging and phone calls and it still drains just as fast.
PLEASE HELP!

I don't know if this applies to anyone in this thread, but after installing a new rom sometimes I forget that the Gtalk/Gchat app resets itself to automatically sign in, and drains the battery while running in the background.
Changing it to not run automatically helps out for me, although I feel that I may have gotten slightly better battery life out of the rooted stock rom than running the King kernel I'm using right now. At least in terms of percentage drop. I never really reset my battery stats or recalibrate after installing a new rom, don't know how much that has an effect on the readings.

This is turning into a deal breaker
Its not latitude, off. Not ANYTHING as it still happens with everything off and all apps killed in task manager.
No background, no live wallpaper (even though i used to have one all day). No music (even though i used to have pandora on a couple hours a day). screen brightness is always low (even though i used to leave it above medium, and would turn it up to high to watch video or a game, and still made it most of the day before).
The phone's battery use thing swears its "Android System" thats taking by far the most, not even cell standby got larger when i unplugged it in the basement where there's no service.
i've turned off everything i could think of, no apps 'auto update' and i've put all syncing and updating and stuff to manual or off that i could find.
I don't think its a faulty battery because it is ridiculously noticeable that something has changed in that ANDROID SYSTEM is now a power hog. Why and what do to?????

"Android OS" consuming battery [POTENTIAL SOLUTION]

EDIT
I was able to solve my battery issue by formatting my SD card. Something on there was causing the battery to drain 2-3 times more quickly than normal. After formatting, I went from 6-8 hour battery life to around 20 hours with significant usage (Google, Exchange, IMAP, Facebook all on push, 3G+Bluetooth+GPS on, 4G and wifi as needed for extra speed).
Important to note, I am not entirely convinced that the Android OS and battery drain are related since I still have Android OS near if not at the top of my battery consumption screen, but the improved actual longevity is very significant. I recommend anyone having their battery run out format their SD card (and possibly USB storage) and see if that helps (obviously back up any important data first!). Good luck!
ORIGINAL POST
I'm getting pretty bad battery life, and it looks like "Android OS" is consuming most of it. I've rebooted (as suggested in other threads), checked OS Monitor for high-CPU usage processes, but nothing stands out. This is un-rooted, stock OS with no third party launchers installed.
I have a feeling if this issue was fixed, I'd be getting great battery life. This happening to anyone else?
Screenshots show the device at 38% after 6.5 hours off the charger.

That's an awful lot of awake time with no screen on time. Do you have things updating in the background frequently? I.e. social hub, Facebook, news widgets?
And not to be too obvious, but is your 4g antenna turned on?

No, I don't. I have fewer widgets and fewer accounts (haven't set up my work Exchange yet) than I previously had on my EVO, which got great battery life.
I've been on Android over a year and am quite familiar with how it works... I'm just unfamiliar with Samsung specifically and unrooted devices and was hoping someone might have a similar experience.

I have the same thing. Significantly more awake time then screen on time, and Android OS eating the battery. Also stock.

Same here too

I had this exact issue and no longer do. Here is what I did and posted in another thread:
OK I hope someone finds this useful and/or can verify. I was one of those people getting awful battery life, meaning lucky to last 8 hours from 100% to 0%. The "Android OS" process would take hours of CPU time. Now it will take up maybe 30 min over the course of the day. Here is the only thing I did between the time it went from bad to good. I changed the wifi sleep policy. It is by default (for me at least) set to never. I changed it to "when the screen turns off" and left it there for about an hour. Then went in and changed it back to never. From the point of doing this my battery life has been great.
I know it sounds strange but it seems to have worked for me so I thought I would share.

I made the change, hopefully it will help, although I'm reluctant since I haven't had wifi on all day and my battery has been dropping like a rock. Here's hoping... will report back if it helps.

I rarely use wifi as well but this setting seemed to affect the phone in general, if your using wifi or not. I might just be crazy though. Either way I no longer have the issue so

does the google voice widget pull data in the background or is it a push thing?

I'm seeing high usage (60+%) by AndroidOS also (stock, unrooted, not using WiFi, not using 4G), although battery life has not been bad that I have noticed.
Watchdog Lite indicates that this is primarily due to two processes:
events/0
suspend

Random power drain

Yesterday as I started my day, i pulled my GN from its charger (99%) and made my journey to uni. The trip takes about 50 mins. For the past month now Ive been using poweramp and have had no problems. But when i got to class i realised i had like 25% power during my trip and the back of the GN was a bit warm. I closed all programs and the power drain stopped. I was a bit concerned so a few hours later when i tried playing music again on poweramp but nothing drained the power. So maybe it was a freak occurrence?
So I went to bed last night and the phone was fine. something around 80% power. I woke up 5 hours into my sleep to check on my phone (its a bad habit) and went back to sleep for another 2-3 hours. When i woke up i found my phone had discharged a whole lot of power again randomly in that space of a few hours.
So what the hell happened in that time?! All I did was turn the screen on and turned it off. My usage patterns have not changed.
here is an screen shot of my power usage. You can see the first drop of power, thats nothing of concern as i was playing angry birds space before bed. Then you see the straight line as the phone was idle while i was sleeping. The next drop is when I woke up to check my phone and that's when the discharging happens again. Then you see it recovering when i woke up and closed all the background apps in hope that it would stop the power drain..which it did.

No new apps, but some app updates. I know at least light flow was updated.
this random power discharge is really getting annoying. It happened again today.
A new symptom seems that the video doesnt load on the phone. for example, trying to load youtube or recorded videos saved on my phone.
Originally i thought my 3g was playing up but when it wouldnt load a video i recorded that was a bit unusual. in fact the gallery app froze and crashed.

Did you search the forum and install CPU Spy and Better Battery stats?
Get some data and find out what is causing wakelocks. Your phone has a lot of "wake" time.
See with CPU spy how much it is spending in Deep sleep and with Better Battery stats look what is preventing it from going into that state. If it's an app: simply remove it.

How's your signal service been lately? I get pretty stank reception at work so my gnex gets pretty warm at the top and battery life suffers. I just put it on airplane mode and reset the radio to force it to chill out for awhile

Thanks ill try that. Just installed CPU spy. Is there an alternative to better battery stats? Don't really want to fork out something to debug this.
I originally used OS monitor, and i checked what was running while the abnormal discharge was happening but nothing showed up.
You make a good point about the amount of wake time though. That long stretch where i was sleeping, my phone shouldnt be waking up that much should it? It didnt seem to affect battery life that much.

Better Battery Stats is the one I use and is recommended here a lot. It gives you insight in the wakelocks from the kernel, as well as from apps. Don't know about the alternatives. It's definately about the wakelocks. Your phone should be in Deep Sleep for 90% or so when you don't touch it (depending on your sync frequency off course).

It's so strange because before these problems came about I had good battery life. ie: 3+hours of screen time.

You usually set it at System Settings, accounts & Synchronisation but some apps allow you to set it within the app... There are apps that allow you to make profiles so that, for instance at night, your device turns off all data. I used to use Juicedefender but that was IMHO more a placebo effect then a real improvement.
I definately think you should install the mentioned apps and after such drain re-appeared analyse what happened.

So after a little bit of troubleshooting I narrowed the problem down to Light Flow Lite.
Last night I went to bed with 100% charge. It discharged normally throughout the night until 4 hours in when I received an email. I woke up about an hour later and saw this so i suspected it was light flow. I cleared the notification and went back to sleep. I woke up about 30 mins later and was sad to see that my fears were confirmed. Battery discharge had settled down and was acting as normal. Just to be 100% sure though, i sent an email to myself to set off a notification and left it for another 30 mins, and as you can guess, the battery started draining excessively again.
Here is the screenshot. First part obviously is when im sleeping. then that dip is the email coming in. That TINY TINY dip upwards is another email coming in a min after I cleared the original email. So the battery drain continues until i wake up and clear it again. This time no more notifications came through and the battery drain settles down.
Again keep in mind that I have used Light Flow Light for 2 months now without problems.
Anyone else experience problems with Light flow or Light Flow light since it was updated on the 20th March?

I have been great with my light flow lite..I had a problem with my own battery when I updated Google chrome.. uninstalling that fixed my problem..

[Q] Android OS Battery Drain

In the last few days, I have noticed that the process "Android OS" has been using maximum battery life (about 16-35%) and has also been consuming large amounts of data.
The only thing I have done recently is allow the facebook app to upload all pics from my mobile.
Any connection? FYI, I have not added a Samsung account.
Apologies if this has been answered earlier by I did search for it.

what version of android are you running?
what ROM? what kernel?
how long ago did you start to notice this?
is it a constant issue, or does it fix itself after a reboot or something, or with data connection turned off?
do you use google now?
if you are on the jelly bean 4.1.1 version, did you update OTA or odin? just curious, probably not related anyways...
what recovery are you using?
just trying to get some info before i help. many things in the android OS can be directly or indirectly related to each other but still have a side effect on battery life.

16-30% in general has been relatively normal on JB. (Usually between 14-18% is where it settles to)
Keep in mind that unless you are at least halfway through your batt cycle its going to be higher. If you're at 90-95% batt it can be much higher, just due to percentages and battstats being reset.
Not sure why you didn't find anything though, this has been covered a great many times in the past 6 weeks! Did you look at what the top processes are under Android System?

I had installed root66 prerooted JB rom. When I noticed the problem, I installed stock ICS through odin, updated to stock JB then rooted again but the problem continues.
I have been noticing this for about a couple of weeks. Restarting doesnt help but I havent yet tried turning off data. Will try that and let you know.
Yes I use google now.

Is this something peculiar to JB? I didnt see this in ICS. The top processes currently showing in the battery stats are Android OS: 28%, Voice calls: 17%, Screen: 11%, android system: 8%...
Is there anyway to check exactly which app is using the battery and data which is showing as Android OS?

Odd... mine is usually only around 10%

Mine generally sits between 11-14% depending on use. But it can show 30+ if you check it at certain times.
For example, if you've fully charged the battstats will have reset. If you reboot the phone it will kick off the media scanner which can run for a while (this can also be the cause of it heating up for a short time). So once its complete it will have used a rather sizable chunk of the overall battery use. Since it usually doesn't run again, the percentage will steadily drop as other processes use the battery.
I know we aren't really discussing the media scanner, but I use it as an example that is pretty easy to see if you watch it.
Android system has a lot of processes which are listed under its category so depending on how each person uses their device it can vary a bit. Most screenshots of 'normal' reports that I've seen usually are around 14-18%. For me its lower, but I'm pretty sure I don't use mine the same way others do. There are times though where it can go higher for me, depending on what kinds of stuff I'm messing with or testing out.
I believe transferring large amounts of data over mtp is one thing that can cause it to go up...
Hope that makes sense.

my phone just started this last night. i took it off the charger around 11 last night (100% charged) and it woke me up at 3:30 with a low battery indicator, i checked task manager and nothing was open battery stats showed that android os was at i think 38%. i put it on the charger this morning at around 9 am because it had died fully. it's now 1 pm and it's at 95% charged, typically it takes only a couple hours to charge. my phone is fully stock running jb.

What kernel/ROM and version of recovery are you using?

You can track data consumption of Android system apps via Droidstats
You'll be able to know wether it's Google Maps or any other service that uses data

I am fairly confident I've tracked it down to the touch sounds. Sounds dumb I know, but I believe they are wake locking excessively. I have much better results with ANDROID OS drain with them turned off. Interested to see if others do too.

Hey there,
im having a similar issue with my Google Nexus 10 running stock Android 4.2.2 (fresh install of factory image and then manual update with ota update.zip).
Here are two screenshots (didnt want to include here because they are HUGE and I dont know how to resize them in forum "code"):
One
Two
I havent been using it much the last days and im a little spoiled by an iPad 2 standby time so this is not very acceptable
I'll try Droidstats and see what I can make out of it.

Looks like you haven't used the tab (screen time) that much over the two days, making Android OS seem overtly guilty.
Try disabling touch sounds -- settings-sounds- touch sounds
Then let us know. I am convinced that is the culprit of the wake locks, keeping the Android OS (kernel & drivers) high and eating battery.

Sorry, forgot to mention it. I have them disabled since i own this tablet (and I checked it again).
I wanted to try DroidStats, but it seems to be an app for calls, sms and data
Can you post a link to this app (if its allowed )
EDIT:
Yesterday a friend of mine showed me the battery stats on his Galaxy S2 and had almost 40% "Android OS".... but he has never had better battery life. I start to think that (because of the percentage system) the built in battery tools are almost useless
Is 4 days a normal standby time for the Nexus 10? That would be very bad in my opinion.

I've just started seeing the same thing with my Galaxy S3 (Samsung issued ICS, rooted). Normally the battery will last around 24 hours with light use, but currently it's draining from full to warning level in about 4 hours with the screen mostly off (wi-fi, bluetooth and GPS are off at the moment). Touch sounds have been set to off from day one.
Yesterday, the culprit looked to be Beautiful Widgets (around 38%) so I turned some of that off (weather update animations, etc) but I'm still getting the same drain speed - now showing Android OS 26%, Cell standby 22%, Android System 15%, Screen 11%. Not sure if I trust the results though, the BW issue from yesterday could have been a red-herring.

[SOLVED!!]
i have this problem with my galaxy grand phone ,the battery discharges in 20hr , default OS was 4.1.2 official samsung , i changed my rom into a slim custom rom based 4.2.2 , but the battery has same problem again , Android OS battery Usage Was 80% !!!! and screen usage just was 9% !
my installed software :
Viber
WeChat
MyKet {Like Android Market}
Weather Widget
i used wifi 1-2 hour in a day ,
=================================
[SOLVE]
first go to Settings -> Developer Options -> Apps Tab -> checked Don't keep activities
set brightness to auto
then go to location services -> off access my location
then go to wifi -> advanced Wi-Fi -> keep wi-fi on during sleep -> change to Never
now go to application manager -> Running Tab -> Force stop some apps with extra ram usage like settings
my phone just uses 5% battery in 13hr sleep mode ; ENJOY!

Nexus 5X battery more than worse!

So..
Recently I've bought my very own Nexus 5X, here over in Europe.
I have been very, very happy with it so far!
I came from a S5 mini, but boy oh boy, I'll never buy a Samsung ever again!
Though, I've recently ran into a major problem! My battery is so, so, so bad!
I could speak of luck when I make it trough 6 hours!
My S5 Mini was even better than this one, and is instead 2200 mAh!
The only thing I do on a day, is check Twitter and visit some Android news pages..
Not even a heavy gamer!
Have I done something wrong? Is this a manufacturing error? Is Google fixing this soon?
Many question, such wow.
I would love to hear from y'all!

(Sorry if I spelled some things wrong )

Share the screenshots (Power + Volume down for 2 sec) of battery stats and it will help the others to decide who is the culprit. You can see who is using most of the juices in battery stats. Also, in Developer Options, you can see what's running in background from 'Running Services'.
In general, the battery is quite satisfactory.
For me, 5X was getting very poor cellular network reception and it was draining the battery. I choose '2G' from Preferred network type (reboot) and it's improving already.

Sup?
Thanks for replying buddy! It's really awesome to see some support out there!
XDA doesn't let me post image's.
Right now, I have 4 hours left while I booted my phone 2 and a half hours ago..
Chrome is taking up 8 %
Screen 7%
Android OS 3 %
Android System 3%
Google services 1 %
I can't even get through half a day.. Ugh.

Hi!
See the Network reception first. For a clearer view, download this app: Network Signal Info.
And head to this thread and see if anyone else have already answered your query: http://forum.xda-developers.com/nexus-5x/general/nexus-5x-battery-life-thread-t3229424

Sup?
Network is all good, not really that much problems whatsoever.
I just don't understand why this phone does this to me..

When you look at your battery stats, tap into the "graph" then look at the bottom and see the "awake" line.
It indicates if your phone is "awake" most times or not.
If I constantly use my 5X throughout the day, 6 hours sound about right (this was when I just got the phone and was constantly playing with it).
Now I just use it normally for messages, emails and calls throughout the day with occasional clash of clans and it could last an easy 13 to 14 hours. Just a note though, I do use the app greenify.
If you noticed your phone is constantly "awake" even if when your not using it, then maybe consider turning off the "ambient display" (in display settings) and see if that helps.

Sup?
Thanks for the reply! ^^
My battery is indeed constantly awake, I don't know how though!
It's all normal usage I'm performing, I don't even play any sort of game..
Never heard of Greenify.. Is it like a boost app..?
I did turn off Ambient Display. I have the official Folio case, so Ambient Display is useless anyway.

Umm.. Anyone who have options left?
Because I'm kind of stressing out now..

It's weird your phone is "awake" all the time. Maybe there is bad app installed.
Try using the greenify app and see if it improves the battery.
This app prevents other apps from running in the background.
If this fails, try factory reset and use see it this improves?

One of the apps or services you have running on your device is not letting your phone go to deep sleep or Doze, by the sounds of it.
You can see which apps you have running 24/7 in the background in Developer Options > Running Services. Any of those 3rd party services could be causing your issues as they do not close when you swipe the app away.
You can also check Settings>Memory (sort by max usage at the top right options) to see which apps are using CPU and RAM periodically throughout the day.

To kgen:
I haven't really got the time to test it now, I charged it since the battery almost died..
Greenify doesn't do the trick.. It doesn't detect 1 single app..
To bblzd:
There are not even that many services!
I've aksed those Google product forums as well, told me to try a day in Safe Mode and clear device cache in boot menu.
Just cleaned the cache, off to bed now, and try Safe Mode tomorrow.
I kind of lost all hope man.. I don't know what to do anymore..

You are using Android, more precisely a NEXUS and you are losing hope already!! Unless it has some manufacturer error, it will be solved. Start sharing the screenshots. If you can't post pic, post link. Let the experts go through them.
Best of luck.

Well, yeah..
It's just really frustrating that I finally think I have one of the bestest and purest phones on the market, and it just really isn't somehow..
Booted my phone today into safe mode.
I'm losing battery already! I don't understand!
Cleaning that device doesn't do anything as well..
Let me make some post till I get to 10.
Then we can get started.

See previous post.

See previous previous message.

See previous previous previous post.

Okay, let's get started with evidence now.

^ Fully charged my phone yesterday when it almost died.
Booted it, just checked Facebook and Chrome as usual.
And this is the result..
^ Booted my phone into Safe Mode today.
Result's are worse as usual.
Hope this can clear some people's minds.
Help, is really appreciated!

Clear cache and data for chrome. It shouldn't drain so much.
Or are you using it for push notifications?
Clear all Facebook and Twitter tabs and see if it helps.

Cleared Chrome like 50+ times already, so that isn't the case.
Nope, I use the apps not the web versions.
Battery now at 46%, unbelievable..

Tap the graph so we can see more usage info like screen on, awake, etc.
