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'm running stock rooted for e980 and have pretty good battery life .... Try clearing Google play services data and rebooting ... Check and see what's draining your battery mol its pretty easy

I'm also running stock kernel, and have great battery life on kitkat. Just reset your phone to factory defaults

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.

Have you tried reflashing your firmware, instead of just doing a factory reset?
I assume you are rooted since you are using BBS and wake lock detector on KK. Why not flash a custom rom?

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.

Will report back if I see anything noticeable.
How would this this battery though? Like, what does it do? Are there any adverse effects to removing it?
EDIT: BTW, I know you weren't addressing this at me, but I'm still trying it LOL

I didn't see this part of your message, but I just had to respond lol
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.

I stumbled across this post and tried that fix. I'll check back in later to see what it does.
Me and my partner both have HTC ONE x's, Endeavouru, round a similar age, but her phone recently started draining battery.
Both running ARHD, with the same kernels. First I checked if apps were responsible, wiped and reflashed the ROM and kernel both.
This did not work, so then checked battery health with *#*#4636#*#* - showing the battery was in good health, but then replaced the battery anyway to eliminate any possibility of this being the culprit.
Now it's still giving massive drain - a charge up to 100% will last up to 5 hours of standby, with only mobile network activity turned on, all other radios off.
Been throughout the forums and other websites looking for any solutions to this problem but not striking any luck. Tried resetting the radio, changing it to LTE (Not even available where we are), and back etc, as one thread suggested, turned radio completely off and back on. Tried super cleaning the system before reflashing the ROM, tried a different kernel, an AOSP ROM, and still no luck.
It just all of a sudden started to do it, similar conditions to my phone, which makes it harder to pinpoint.
Any new idea's to bring to the table, open to any.

try downloading wakelock detector and seeing what keeps the phone awake and then uninstalling/reducing its privileges
the privileges part can be done with xposed and a module called appops

Well an update to this thread...
Went to install wakelock on the phone after having it turned off for a few days, the battery was drained and now every time I try charging, regardless of what I use re ac/computer/original/aftermarket charging equipment, all it does is heat up to about 58 degrees C and stop charging - with phone off or on.
Sucks as it seems to be a manufacturing fault, but since I've rooted it, and purchased 2nd hand, looks like one for the rubbish bin

Surely if it's the light sensor it would be irrelevant if it was turned off or on though, same with the CPU. I'm going to spend some time getting power into it today, charge, then put in freezer to cool it, and repeat.
Once some power is into it I'll start with suggestions, one at a time, and get some screen shots up, and logs of the current drain.
Thanks for the help so far, would be good to get it going again, instead of having a $350 paper weight.
An update:
Changed the recovery from Philz recovery to an older CWM recovery program, and now possibly just through coincidence the battery isn't super heating to the point it needs to live in the freezer to charge.
I have restored to stock ROM, and have a couple of pictures of the battery history, which are neither here nor there, apologies as I wiped a lot of things off, including my WLD pictures from the ARHD ROM.
I purchased trickstermod and had a look into the CPU settings, and nothing seemed out of the ordinary. Also turned on the dev options of graphic CPU usage on the homescreen - not really showing unusual signs of anything. About to flash the original recovery on and email HTC to see if they might feel sorry enough to accept it as a straight manufacturing defect, without evidence of where we purchased it (as it was a second hand phone off the net).
subscribing to this thread - I have the exact same issue. I have installed CM11 and ParanoidAndroid. Torched and Bubba kernel... turned off lots of stuff.
I have whatsapp, soundcloud and facebook as the only background running apps. not sure what's the issue
sensors drain battery
Hello!
I also have a similiar issue.
I noticed, after a while, that my phone keeps dying under 16-18 hrs on idle from full charge.
I thought it1s the battery, since my HOX is 2 years old. Someone suggested, to try some battery monitoring, so i got the battery monitoring widget, after for like 3rd time, the phone turned off overnight.
The problem, is the Light, and the acceleration sensors... they won1t let the phone go to sleep.
I tried turning off locations, and such, also auto rotation, and my back light was never on auto. it is set around 30%
Still, these sensors run, and consume battery like crazy. This started about 2 weeks ago.
I have a stock rom. not the original, since i thought flashing a custom rom might solve this, so i tried ViperX 4.1.1, the problem was still there.
After that, i reflashed an untouched original HTC JB rom.got the latest OTA update, and the problem is still there...
I don't have any apps running in the background, that should require these sensors to run. i always clear multitasking also.
Have Wifi on, but that barely consumes anything.
Any idea, i know this started on Gingerbread, and was supposedly fixed in ICS, but it's still happening to some ppl.
Any help would be appreciated!

I have checked all the sensors in the testing menu by dialing *#*#3424#*#* and they all turn off and on as required properly. I noticed yesterday that I've actually burnt out the charging system as it has got too hot at one point, so no use pursuing anymore. I will stick with my HOX until it too breaks in some way. Received an email back from HTC saying "Not under warranty, not our problem" after asking if they had had any phones with similar issues pass through.
I have had my P607T for a couple of months now. It is box stock no changes. Over the last few weeks I have noticed that it will reboot while using various apps. (Fliipboard, Chrome, Clash of Clans, Papyrus...) They don't seem to all be heavy graphics or network. The only symptom is that the screen starts to flash then "bang" reboot (and trouble rebooting when not plugged in). It would not be too annoying except that it will loose wifi settings and the wallpaper. I have tried different wallpapers (saw a thread blaming the live wallpapers ) Unloaded some apps (had another phone issue with FitBit and HTC blink on my N4). I stay away from CoC (my base has been raided so often now ...). Any thoughts? I am really trying to like this tablet more than my old ASUS Transformer but this reboot and reset wifi is a pain.
Thanks in Advance,

Have you tried a factory reset? I'd make tmobile replace it
was hoping to avoid the reset button. Tried it and still giving trouble it rebooted while restoring apps. I bought the tablet on ebay, I don't think TMO will take it back. oh well I'll keep poking about.
thanks,
I experience exactly the same problem since the update to 4.4.2 (kitkat): The screen starts to flash, suddenly the tablet reboots. I tried a factory reset multiple times, also removed the SD card and reflashed the ROM via KIES, nothing helped so far. Also, even when plugged into the outlet for several hours the tablet didn't charge at all (I think it stopped charging when the screen saver kicks in).
A couple of weeks ago I filed a RMA request (my dealer sent the tablet to Samsung), yesterday I got it back. It was charged at 60% and when I plugged it to the outlet it actually charged (even when the screen went off). But after about one hour (the battery was still > 60%) the flashing reappeared and after a while the tablet started to reboot again. Interestingly the battery now showed only 2% and the low battery warning appeared.
I think the problem might occur only when the battery runs low (which happens very fast as something seems to drain the battery), while android still shows a much higher battery level . Never experienced these problems when the tablet was plugged in so far.

At least I don't feel so alone with this issue... I have been paying more attention to my build up process since the factory reset. I found, the other night quite by accident, that when I logged in to Twitter the reboot started. So for the next few days I have left Twitter off the machine and it is doing better. I suspect that something is hitting the power drain (like you mention) and that causes it to have problems. In that thought I have also turned off the power saving mode and auto screen now just to add to the list of things I am avoiding.

At least I don't feel so alone with this issue... I have been paying more attention to my build up process since the factory reset. I found, the other night quite by accident, that when I logged in to Twitter the reboot started. So for the next few days I have left Twitter off the machine and it is doing better. I suspect that something is hitting the power drain (like you mention) and that causes it to have problems. In that thought I have also turned off the power saving mode and auto screen now just to add to the list of things I am avoiding.

Have you considered rooting and using root apps to stop the apps from being able to do such things?
About 3 days ago the battery drain on my Nexus 5X went crazy. I found out that the "app" Android System do not let the phone sleep and keeps it awake all the time. That is why the phone can not even get into doze mode and drains about 8% per hour when the screen is off. I tried restarting the device and also force stopping the Android System. Both without any succes. Do anybody knows what to do with it? Or should I just wait if it will go back to normal? I do have screenshots, but the XDA will not let me post outside links...
Interested about that.
Ur screenshot may be useful, host them in a site like imgur and replace dots by other letters.

Well just delete the two underscores and the "dot" thing
I am having the same problem. It occurs randomly, most often when I have just charged the phone and removed the cable. If i am correct, a wakelock under the name *backup* is holding the phone awake, it might be the same in ur case. I've done a research on this, turned out this is unfixable unless you have some sort of wakeblocker, which my current rom lacks of. I tried using xposed with its modules, but it gave me a ton of bootloops and i gave up on it. The only temporary fix for me is to reboot the phone. Until it happens again. No clean flash nor anything i have tried seemed to have helped. I even tried disabling all services and receivers from Android System, no luck again. That is one hefty problem

I have exactly same problem with wakelock. It happens only after charging. Everything is OK after restart.
It has happened to me sometimes on my old HTC One X and I think it happened also once on this 5X, but it was just for about a day or so. It disappeared itself with time, I didn't do anything with it then. Now it's been 6 days, I have to charge the phone twice as frequently and neither the reboot nor the force stopping everything works. I really don't know what to do in this case. Also this phone isn't rooted yet, so I can't just flash the system again as on my old HTC... I'm still hoping it will disappear by itself asap
But do you anybody have any other ideas what can I try to do to stop that crazy system app?
same problem here...
had the phone about 350 hours with no restart and i thought i would give it a reboot..
same think happened...android system was going from 2% to 20% in a matter of hours..
installed an app called GSam Battery monitor..showed me the phone was not going in deep sleep (Doze mode) at all...
here is an attachment if anyone can understand better than me..
I posted a similar thing in the battery life thread. Very odd really as I've had the phone a few months now but it also only started with me a few weeks ago. Really can't think of a trigger for it... I doubt the April update would have been significant enough to create an issue, but who knows.
Exactly. After about 4 months of working excellently and about 400 hours without restarting, after charging it's immediately goes into this "mode" when the Android System won't let the phone sleep. Even restart didn't help me, but now after 3 restarts it goes to normal. One bad thing... after every single one charging, every time I put the phone on the charger it goes crazy again and I have to restart the phone after every cutting of of the charger... it makes me really angry when the phone is only 4 months old and even the "okay" battery life isn't that good on this phone... God I just need to find a solution, that's insane...

THIS!!!!
the phones battery life was a big "ok i can just play a bit less so i can get through the day and IF anything happens i know it has fast charge so ok"
nowadays i have to reboot after EVERY charge....
p.s.
anyone that faces the same problem but WITH mai's security update? do we have any hope that it will fix that problem?
Not sure if it's a one-off, but I decided to uninstall the game "8 Ball Pool" by miniclip as it appeared on my battery usage stats when I'd not opened it in days. Since then, even after a recharge, the phone seems to be going to sleep as normal.
I'll monitor to see how things go but perhaps it could genuinely be a rogue app. It's a little disappointing that doze wouldn't block the keep awake requests - I thought that was one of the main purposes of it.
The same issue occurs for my Nexus 5X: after device disconnected from a charger, Android System process starts to keep device awake until next restart. As I understand from comments above factory reset does not help to solve a problem. Has anybody met the similar problem with custom ROMs/kernels?

It started with the latest update I think. It hasn't happened once ever before. I hope they already know what's happening and with the May update it will be gone. I don't think there's any other solution when you don't want to flash custom ROM and stay on stock... :/ we have to wait.. :/

Hmmm, sorry for offtopic clarification... as of now I'm little bit confused about Android versioning, especially it's unclear for me: whether you mean as latest update: 6.0.1 or april security patch or model build number (like MHC19Q, which is currently on my device)?
I guess it must be April security patch. Some kind of problem in the Android System app that comes with the security patch. I don't really know in this case, but as I've said, it hasn't happened once before the April patch

I rolled back to MHC 19J. The April MTC19T Build cut my battery life in half. Android system being the top culprit. Deep sleep never going over 80%. Horrible idle drain. Would drain 15% over night while i slept. Exact same setup as before, no new apps. SOT went from about 5 hours to not even 3.

MTC19T is May update. I've updated my device to it yesterday and the issue hasn't been fixed yet: a device is still kept awake by Android System after disconnecting from a charger. @ScumDroid, could you please confirm there is no such issue on MTC19J after rolling back?

Same issue. After running it for few months flawlessly, the Android System is keeping the device awake and only restarting it solving the problem temporarily. Charging the phone again starts the wake lock..
Most disappointing is it's the 'Android System' that causing the problem. If any app/game is linked to this, it should have been appeared as the culprit but unfortunately it's that 'System'.
Waiting for solution.
Samsung users are having the same problem.
I have found something on my Samsung Galaxy S6 in regards to 'Android OS' killing the battery. It might be the same for Nexus users, I've confirmed this on a Moto G 2015 running the latest MM update and on a Samsung Galaxy S6 Edge. By latest update, I mean the April security patch.
Check this and this.

Sorry for the late response mate. I have no issues with android system draining battery in MTC19J.
Hi all,
I got a new battery a week ago, because my phone didn't turn on or charged anymore.
But my battery keeps draining. I lose around 25% in idle at night time. And around 3% every 5 minutes when I use it.
I used gsam for a few days now to see iff there are any applications that are causing the drain. So far I can't discover any.
Also when I'm using my phone the side of the power button gets hotter then the rest of my phone. While the battery and cpu both are under 40 C.
I do have android 10 and 2.1 ui from devbase rom with soldier 6.0 clean installed, tried other roms aswell, so maybe I should get back to android pie?
I also started using ex kernel with the standerd underclock option you can choose while flashing this helps a bit.
Hopefully somebody can help me out.
Some gsam data
I have the same. I used different roms and kernels, all the same. I turn on airplane mode for the night. it helps a bit.

Thank you, this reassures me that It's just a coincidence that my battery died, and that the behavior of my phone at the moment doesn't mean it would happen again.

I do notice, that gsam says that that I am using wifi all the time. And it shows that battery usage is high when this happens.
The only thing is that I never use wifi anywhere..
I don't know if this is something to go on or just normal behavior?
