Hey everyone
Got a Nexus a couple weeks ago after having iphones for a couple years. Loving it so far.....ICS is very polished.
Initially, my battery life was adequate. However, recently the OS is using 45% battery and the phone gets a very hot when idle (I can feel the heat in my pocket)
I did a factory reset and still the same problems.
Is anyone else coming across these issues?
An old bug cropping up again?
http://forum.xda-developers.com/showpost.php?p=13247149&postcount=57
Can you please install Watchdog (https://market.android.com/details?id=com.zomut.watchdoglite) and let us know if it's the suspend process (which shows up in the battery meter as part of "Android OS") burning through the battery?
My phone has been on standby for about a day and has 80% battery left. However the battery consumption shows:
42% Android OS
37% Phone Idle
16% Cell Standby
- Also what is the difference between phone idle and cell standby
MY BACKGROUND APPS RUNNING ARE:
- Battery Monitor Widget (I need this on so I can tell what my battery life is easily)
- Google Services (What is this, can I kill it?)
Media (What is this app, can I kill it?)
Music (Again what is this, what happens if I kill it/should I? I never used it.)
I have the same problem. My SGN died after 7 hours without any usage.

Yup, me too. This morning, I took my phone off the charger at 98% for an hour and 15 minutes and didn't touch it. The battery had gone down to 88%, with Android OS using 64% and Android System using 14%. The phone was 'awake' for the entire period. I've had my Nexus since Wednesday and I haven't been getting great battery life. I'm hoping there's a fix for this.
Same problem here... (I testing radio UGKK7, XXKK7 and XXKK1... all with the same problem).
- Lightflow increment "Android OS" battery use.
- By using, Wi-Fi "Android OS" uses less battery.
try disable wifi when not on and unchecked "use wifi network" for location.
another thing could be some active widgets, i remember this was a problem a while back.
Note sure that this has got to do with wifi at all as I reset my phone to factory and I still have the 'Android OS' usage taking 23% of battery. I have no apps nor have I yet linked phone to my Google account.
I have read some comments to do with the Galaxy S2 which too suffered from the same problem. I remember reading something about Samsung driver implementation causing this with the S2. I will update the links when I find something conclusive. Also I have another HTC desire that has the AOSP code compiled rom and that does not suffer from this at all and it is happily sitting idle at almost 2 days with nearly 70% battery still left.

Yes, the problem was with the suspend process eating up CPU. You can install Watchdog and set it to watch non-Android processes, and that will be able to tell you which "Android OS" process is actually the one eating up battery.

Is samsung aware of this problem? We need to file complaints.

Do you have your email or anything set up to receive things instantly? That can have a noticeable impact on your battery if so
Thanks Chirality, but I assume that this is happening to all users? Samsung have seen this before so shouldn't this be fixed from the very start? Wrong person to ask this question to, but it is annoying..
Anyways I will install Watchdog like you say, but unless I can kill the 'suspend' process, I am helpless.

No, that's why I reset the phone to factory settings and the current behaviour is without any apps, or registration with google, no emails, nothing installed.

Is there anything in the logcats that could hint to a problem? Like errors or something unusual that it keeps repeating
I have the same problem with high system CPU usage. I used SystemPanel to monitor the phone (unplugged, standby mode) during my 8-hour sleep and here's the results.
The System Processes were using 49min of CPU time while the phone was idle
When I clicked on the system processes I got a list of individual processes. Anyone knows what are there kworker processes for?
When I clicked on one of the System Processes (kworker/u:1), I got its CPU usage. It was doing something almost the whole time
Finally, I should also mention that the phone lost about 7% in these 8-hour test. Seems ok but I think it would be even better when this high system CPU usage is fixed.

Hmm...Now that you asked this, I remember watching logcat output and was getting a null Notification event almost one every minute a couple of days back. I therefore proceeded to uninstall all my widgets/apps but I could not reach to a conclusive outcome.
Anyways as Chirality pointed out this post (Link) indicates a 'suspend' process issue. And this guy identified the process causing it (Link), I think!

A driver issue definitely sounds plausible but there are also a lot of things different between these two phones, especially between GB and ICS.
Watching /proc/kmsg should show something if it is an issue with the kernel

Chrality, xHausx
I have installed Watchdog and set the settings to what you indicated. I am a bit confused around the app, so I have added screenshots to update you of the data at my end.
Do let me whether you see the issue immediately or need any further information.
My experience is somewhat the same.
Out of the box battery life seemed pretty good. After the update to fix the volume issue I started to notice that the battery would fall even when the phone was idle. Android OS was the culprit. I am now running MCR and I have the same issue.
It's not terrible battery life, but it's substantially worse than it was out of the box.
I did wonder if the problem was related to how they fixed the volume bug. Is something always running to pick up the volume bug problem and deal with it when it happens?
Just a thought.

Interesting. I've been thinking the same thing, and the annoying thing about that is the problem doesn't affect my network (T-Mobile), so I could be getting reduced battery performance for no reason! Ah well.
I updated to JB last night, fully charged my phone, unplugged it and then went to sleep. When I woke up I only had 50% battery left, previously on ICS when the phone was idle over night it used between 2-5% max.
I then charged the phone again this morning and now 3hrs 10mins later, I'm already down to 66% and I have hardly used the phone. It's showing as:
Whatsapp 36% !?!
Android OS 17%
Android System 16%
Facebook 7%
HTC Sense 6%
Mediaserver 4%
Camera 3%
Is anyone else having any problems? With ICS I would charge my phone in the morning at work and it would easily last until the following morning, unless I was heavily using Facebook or playing a game. I thought JB was supposed to improve the battery life, not make it worse.
Give it a few charging cycles before complaining.
Have you rebooted the phone since the update.?
Some apps still are not quite complitable with jb,especially with new HTC sense libs or api.

Not me personally, but it did reboot by itself randomly. It's never done that on ICS. I think I'll do as you suggest, give it another day or so. If it still hasn't improved I'll try a factory reset.
What does the Power Saver option actually do? Does it switch off all data sync, lower the screen brightness etc?
Do a full wipe. Some apps could be screwed up while updating.

Power saving saps my power.
3 hours and I lost 20% quick. Turn off power saver and I'm actually saving power.
Hmm I actually think power saver is an amazing feature. 2 hours gone by and I just lost 6% battery (normal usage: message, whatsapp, maps, xda). Even though typing felt weird because no vibrations.

I think they have paired the app with the screen time and gives you a total percentage.
No screen time hours is pretty ****ty.

Most likely an app that isn't backing off nicely. When an app finds your data/Wi-Fi is off is probably getting in a panic that it can't call the mothership (or download some ads!) and is waking your phone or keeping it awake constantly while it tries and tries.
That app would cause the same issue if you turned off data and Wi-Fi manually.

Try Nova, I personally find it better than Apex.
So I installed android revolution 15.0 and the battery doesn't seem to be good at all... Don't know if its a JB thing or this particual Rom. When I check the usage number on power section, it says android os has a 2 hr wake up time... I also installed betterbattery stats and I am getting this wl1271_wake under the kernel section and this weird surfaceflinger under the processes section... Any insight would be helpful, thanks

I performed a factory reset last night - well the new equivalent in JB, which is go to backup and reset the phone.
After the reset, I setup my Google, Exchange, Hotmail and Facebook sync. The only app I installed was Whatsapp. Managed to get the phone to 72% charge before unplugging and going to sleep, I also made sure the initial syncs had all completed before unplugging the charger. This time it went from 72% to 30%, so 40% used while sleeping instead of 50%.
Looking at the stats, I think the battery counters are screwed up. When I first checked this morning, it showed Whatsapp had used just 2%. 10 mins later after a couple of messages, the battery had dropped to 28% and Whatsapp then showed as 32%.
Android OS never used to show much usage, the screen was always the thirstiest, but this morning it Android OS showed as ~30% which then dropped to 22% after using Whatsapp. Perhaps this is due to the screen time being integrated into the app counters as mickfitz said.
As you can see from the pic below, Whatsapp doesn't appear to be keeping the phone alive during the night as Phil suggested:
Surely others here use Whatsapp? Is no one else getting massive battery drain since the OTA JB update?
The only other things I can think of are the company policy settings which are applied to the phone when I setup my Exchange account, or Google Now - but for this I'm just using the default settings.
[EDIT] I'm not using Power Saver mode btw and I don't want to if it shuts off data while idle - it will mean I don't receive Whatsapp alerts
[EDIT 2] I've just had a proper look at the 2nd screenshot. The line chart doesn't match up with the battery % shown. It was definitely at 72% when I went to sleep yet the chart only shows 50%. I'll leave it charging all evening and check the line chart to make sure it's at 100% then give it another go tonight.
not sure if this app will help us to get a clearer picture of what is happening..

Hello, new to the forums here. I recently updated to 4.4.2 on my LG Optimus G Pro and I went from having a battery that lasted all day, sometimes two days to my phone being dead by the time I get home from work for the day ever since the update.
Two days ago I had 1hr18min of screen time within a 6 hours off the charger and the phone was at 15% battery life left. Today, I had 13 minutes of on screen time and at the end of my 6 hour shift my phone was at 40% and dead a few hours after I got home. I have GPS, bluetooth, NFS all disabled and my brightness set to 30%.
Any help would be greatly appreciated, I'm thinking of doing a factory reset and just not updating to the new version of android when it prompts.
Thanks

Get betterbatterystats and see if you phone deep sleeps. If not then check what the wakelocks are in partial wakelocks. If it's a kernel problem maybe you need to flash a different kernel.

i am running stock phone. it is not rooted or anything
Same exact battery drain problem. Im on stock e980 rom (rooted) with no custom kernel.
Gsam battery monitor app is showing the kernel as keeping my phone wake for the entire time my phone has been unplugged.
The problem seems to come and go though. One day itll be fine, but another day the battery will be sucked dry fast.

I've done this twice in the past 3 days....
I'm sick of having to set up my phone over and over again. And this is a new phone too. I just got it Monday under warranty because my old phone broke.
It's getting annoying. I used to get 14-17hrs+ of battery life (casual use, usually ending the day at 30-50% too, so I never even reached 0%) with my old phone on Jelly Bean. Now with Kitkat, I get around 6 hours if I'm lucky! According to Wakelock detector, my phone is awake 85%+ of the day! All it points to is Kernel (Android OS). I see lots of Wlan_wake triggers too, so I suspect wifi, but even with wifi off, the drainage still occurs. And I only have a 2GB data plan shared between 3 people, so it's not like I can just use data all the time either. I actually NEED wifi.

do you have an SD card installed? Maybe you can try to remove that and get rid of all other media from your phone storage. Might be a media scanner problem? Or maybe you can try to disable auto sync, and check if Google play services is the culprit.

The media scanner usually shows up in the battery stats window though, and it isn't. I've had a corrupted SD card on my tablet once before and it caused media scanner to go berserk, but the Mediascanner entry appeared under Settings>Battery as the highest battery consumer.
In this case of my phone right now, it is Android OS in Settings>Battery. According to Wakelock detector, GSam, and BetterBatteryStats, it's more specifically Kernel.

Hi i had the same problem as you but i started digging inside the system of the phone i found the problem but you will require root access. If you have root you have to delet a lib file tand it carrier iq wich run in background and drains your battery the file to delete is libiq_client.so do that and you will see an increase in battery life

I did this on Tuesday or Wednesday.
... I messed something up on my phone while trying to install a custom recovery, so I was basically forced to reinstall everything. I'm on stock ATT e980 ROM (on an E980) + root. I reflashed the Jelly Bean tot file and then did the OTA update with no apps installed.
On the phone that got warrantied, I had flashed the E980 kitkat backup (now has a flashable version too), and the battery life seemed to be much better on it for about a week, and then the issues started there too.
I just rebooted the phone into recovery and wiped cache and Dalvik cache. Many people on Kitkat are reporting that this helps, but only for about 2 days then the issue returns. Obviously, I want a permanent solution.

Yes, I'm rooted and I absolutely hate custom roms. They take out all the features of the phone that I originally bought the phone for, like Smart Screen, the IR remote (yes, I know it can be ported), and the quick memo button. Plus I used custom ROMs on my old SGS2 and they always caused me tons of problems. Crashes, overheating, random reboots, random SODs, etc etc etc. Plus I hate the AOSP feel. I know it's true Android, but I just don;t like it.

I'm still getting more than usual battery drain, but it is better now.
I just got a replacement OEM LG battery, so I will try that to see if maybe the battery is defective. When I got my phone replaced under warranty, they didn't have batteries in stock, so they just gave me back my old one and ordered me a knew one. The old phone was overheating a lot too, so maybe the battery is bad.
UPDATE: OK, MUUUUUUUUUCH better battery now!
I put in that new battery and "recalibrated" it by draining it to 0% and charging with the power off. Once it reached 100%, I let it charge an extra hour, unplugged, and started up the phone.
I also installed Qualcomm Snapdragon's Battery Guru. I set it up so that it's mostly managing app syncing, but I also set it up so that it will not rely on location services to turn on/off my wifi. I don't want to leave my location services on all the time. I don't know how it is on Kitkat, but on older Android versions (ICS and GB), leaving GPS on was a huge battery drainer! I still treat location like it was back then.
Anyways, it will take a few days for the app to learn my usage patterns, but it's already helping by making certain apps only sync when I open them, etc. I suspect that all the wlan_wake wakelocks are being caused by auto-sync but I'm reluctant to turn it completely off since i rely on it to sync my work schedule, calendar, etc between my phone and tablet. I just wish there was a system setting to allow auto-sync to run every X hours or something. I really only need the sync to run every 6 hours or so.
It's been about 35mins now with 6mins of screen time and the phone is still at 100%. A few text messages and the installation of Battery Guru too. This is normal and how things used to be. After a while, the phone will most likely go to 99% and then have faster drain, but it shouldn't be so rapid like before. Earlier today, after 30mins, the battery would be at at least 95% or lower by now! After a full day, the battery usage graph would should a 45 degree angle too! It used to be an almost level, very gradual angle instead.
I should also mention that for a while, I was using a Zero Lemon slim battery (3150mAh). I bought it because of all the hype Zero Lemon was getting here on XDA, but I really regret it now. I used it for 2 weeks (1 week on my broken phone and 1 week on my replacement) and the drain wasn't consistent, even after several calibration attempts. It lasted me all day though, but I'd be stuck at maybe 3% for like an hour, then while in deep sleep, the battery would "magically charge" to 6%.
After I swapped back to the OEM battery, I don't think I recalibrated, so I wonder if my phone thought I was still using the Zero Lemon.
I'm planning to return the Zero Lemon.
UPDATE2: It's been a couple hours now and the Android OS is starting to retreat from the #1 slot in the battery consumption list!
Screen is #1 now and Android OS went from 65% usage to 14%! :good: :good:
UPDATE3: :crying: OK, it's broken again. I didn't do anything to the phone, but when the phone hit 50%, I left it alone for 2 hours and the battery drained 30% while it was supposed to be sleeping. Android OS is back up to 80% usage!
Wifi on, Location off, Bluetooth off, auto-sync on. I'm trying auto-sync off today to see if there's any dramatic improvement.
UPDATE4: I might be on to something now. I noticed 2 things: 1st, when the screen is off and the phone is SUPPOSED to be in deep sleep, the back of the phone stays warm to the touch. It wasn't hot, but it was warm enough to be noticeable. 2nd, I had System Tuner installed yesterday but uninstalled it this morning. Despite uninstalling and rebooting, the phone was still draining battery fast (I still lost 25% in 2 hours today!). I noticed that System Tuner had added a script to System/etc/init.d, so I deleted that and rebooted. Now the phone seems to be sleeping (says so in BetterBatteryStats and WakeLockDetector), and the back of the phone is COLD to the touch when doing so. I took a shower today (I take fairly long showers too LOL), and then checked my email, and the battery life didn't decrease at all during that time while it was asleep.
Obviously, I need to test this throughout the day now, but this is definite progress, if not the solution.
Also, on my warrantied phone, when I had the Zero Lemon battery inserted, battery drain was high (battery's fault), so I installed System Tuner then too, trying to tweak the phone. After switching back to the stock battery, the drain remained, but most likely due to System Tuner's script.
Then when I got my replacement phone, I ALSO installed System Tuner and of course, I got battery drain issues! I factory reset, but did not install System Tuner, but the problem still remained. However, it probably remained because the reset doesn't remove system files, so this script was still in the init.d folder.
FINAL: I ended up flashing the stock ROM again (I used Eazy Kat 1.0 this time). My phone began bugging out on me. Random crashes here and there, mobile data randomly disappearing (no LTE/4G/3G at all), and worst of all, people were having difficulty hearing me during calls. Reflashing seems to have worked perfectly this time. *knock on wood*
FYI: The last flashes I did, I used .tot files to flash back to stock Jelly Bean and then updated to Kitkat via OTA.

Hi i had the same problem as you but i started digging inside the system of the phone i found the problem but you will require root access. If you have root you have to delet a lib file tand it carrier iq wich run in background and drains your battery the file to delete is libiq_client.so do that and you will see an increase in battery life

I stumbled across this post and tried that fix. I'll check back in later to see what it does.
I have some what of an odd problem with battery life and this rom. I've looked all over the net with just battery problems, and tried a few things. The most common problem I had when I was on 9.1 of this rom was my phone radio was always using around 40% of power even when wifi and data was off or just having one or the other on.
With 10.2 the battery life is much better, so was with 9.1 when I first installed it. I'm very new to this, this is my first rom, my first root.
First couple of days of installing the 9.1 AR HD my phone would be 100% through the whole night, and I'm talking 8+ hours of no use with 100%, not plugged in. Couple of weeks of use, and every night I would start losing 10%. I install the 10.2 AR HD update and again, phone lives through the night without even losing a single percent, then slowly starts losing more and more every new day when asleep.
A new install usually last me about a week and a half of battery life, then slowly starts draining faster where the battery is only good for a couple of days. What is causing such a major decrease in battery? Should I try clearing anything in the restore UI like catch and delvik, not sure what the second one was called?
I use the phone mostly for music, a phone call here and there, texting. And like I said, the very first install or update would get me about a week and a half, then starts degrading.
Thank you for your help.
Maybe a rogue app? Did you try not to install any apps after a factory reset to see if you have the same behaviour? You can also install an app like Gsam battery monitor or betterbatterystats which will tell you what is draining your battery
Yes, I have gsam, and that's where I knew the phone radio was being used at 40%, everything else looked normal. I also don't have many apps installed.
But like I said, the battery performance degrades after a week. I could start uninstalling things, don't think that would help me much as I only have less then 6-8 apps.
Try installing betterbatterystats. The partial wakelocks setting might give you more info

By the way do you have some Gsam screenshots to share? Maybe your phone signal is low and that's what's eating the battery
much hshysfo
Ok, so I cannot post links yet or anything like that. So maybe this will work.

Seriously I wish I had your stats. There is absolutely nothing wrong with your phone. 18 % in 19 hours is fantastic. What you see as radio 21h there is the same as phone active. Basically if your phone is not on airplane mode then radio is active. Nothing to worry about
I only did the update a day ago from 9.1 to 10.2. The problem I had with 9.1 was that after a few weeks of use, the battery life started to get bad. Which is why I'm trying to figure out if there is anything I could try when or if it starts happening again.
Or to be more precise, what would cause the phone to be so good for the first week of installing the rom then start degrading. Because that just makes no sense.
Hey guys,
I buyed my g4 ~2 months ago, and for some days the battery drain is sometimes huge (30%/hour) and sometimes I'm nearly losing 0%/hour... The android core apps are using 31%, the screen 23% and the play services 17%... I'm using the standard rom, didn't change anything, didn't root my phone... And I don't really like to factory reset my phone. Sync is off, only Wi-Fi with 3/4 bars and didn't use it, but lost 30% in one hour... Would be nice, if someone could help me...
Seriously? No one has an idea? I'm kind of disappointed
Do you live in an area where the signal for calls and texts are bad because that can cause battery drain...

Also even though you are not rooted you can still install greenify to put some apps to sleep , and antivirus , facebook and facebook messenger can also drain your battery quick also have you sideloaded an app or game because sometimes an app from somewhere other than the playstore can cause problems..
Try wiping the cache in recovery. This will retain your data.
I have the same issue, but it only started after I rooted my G4 (H811). Today it went from 50 to 0 in 3 hours, while I was asleep...

Can you check to see what is consuming so much energy?
Maybe there is some program, or memory leak, or something that you can identify as the culprit.
This is assuming it's something running on the phone's CPU sucking all the power. A much easier thing would be if your problem is low signal strength, because that is a tangible thing and easy to see, where you don't have to try to track down the mystery app.
I would recommend to wipe the phone completely. I had the same issue and it was an app that caused horrible batterydrain. If it doesn't help and the signal in your region isn't that bad it might be a hardware issue and you should ask your retailer.
try to use your phone in flight mode,
if your battery still drain, maybe its because the battery (hardware) or the wrong calculation of precentage of the battery.
if its not draining, its might be caused by your bad signal, as i had nowdays,
I had the exact same issue. I did a factory reset and it helped a bit (it didn't get AS hot as it did before). However, I just upgraded to 13B and the issues are completely gone. Although 13B seems to be running better altogether, I think the MAIN reason why mine was getting hot is because I had LOCATION set to "High Accuracy (GPS and networks)". I live in an area where my connection constantly changes from LTE to 3G, even down to 1X. My phone was trying to find my location all the time and it went nuts whenever it changed to 3G or 1X. Right now, it's set to "Battery Saving (Networks only)" and I've had NO heating issues. My battery is lasting twice as long, or so it seems.
Hope that helps.
you have bad apps misbehaving or else settings wrong, remember, temperature is tied to battery drain, solve the temperature issue and you will solve the battery drain, my H815 gets crazy long battery life, I cannot run it down in an entire day! - right now my CPU temp is 85 °F (29 °C) with a few things running, such as music
I sometimes spontaneously get an app that will drain my battery faster than I can blink... I force close it when I identify it and all is normal into some other app decides to behave the same.
First was a Kohl's app then was ESPN
