[Q] Is there a problem with my battery?

Hi,
Is there something wrong with my battery? This is the second time it has happened to me .. last time I left it overnight at 45% and when I woke up the phone was off, so I looked in battery usage and saw that it fell to 0 right from ~25%, and today, I was in an international call, and the call cut off and the phone shut down. It wasn't hot at all, I checked.
Is there some bug with the software, or is it a problem with my battery?

Can you check in the setting menu, where the battery is used for? There must be some or one thing, maybe a constantly updating widget, which is faulty, it really take me 1.5 days before my battery is flat with internet on all the time, and 3 days plus with internet off.
On the other hand I had the same with my lg a while ago and after a flash it was OK.
Sometimes these kind of phones behave very unpredictable....

Oh I'm not worried about the battery life, I was putting it through a lot of use.. and I have a lot of widgets updating frequently
My concern is with the sudden drop from ~25% to 0 which has happened twice now

your battery might be wrongly calibrated.Download battery calibrator from market.charge to 100%,click calibrate battery..it should fix your problem

This happened to me few times. The last time I noticed was from ~48% left it overnight (only about 6 hours) and I woke up to find the phone was off. Usually my phone loose about ~25% overnight. Not sure what or who is the culprit. I have flashed few firmwares and none fixed the issue. Currently I'm rooted using Generic World firmware with locked bootloader and removed many bloatwares.

I've this program installed and I'm sure it has not helped with this issue. I see "missing data" when there is a sudden loss of battery.

I´ve also the problem; my arc is not rooted, so there is no chance to calibrate the battery...?

Had it once, took the battery out and in again and it had 20% more again. Then I charged it at home and so far it works fine.

Thank you. I´ve taken out the battery for about 15 minutes and put it in. The percentage is still as before.
Is there another way to reset the batterystats.bin without root?

Well looks like many people are having this issue, either there are a lot of faulty batteries out there, or its a problem with the firmware. I'm leaning towards the latter.
I'm using Rogers 2.3.3, what are you guys using?

I experinced this issue with Singapore generic firmware as well as World Generic (current) firmware. Hence I don't think it could be a specific firmware issue.

Awake
Anyway to find out what or which program kept the phone to stay in awake? As you can see the screenshot, the phone was awake during random times and most of the time without the screen isn't on.

Sorry, no idea,perhaps someone else here can help
For me its probably something like latitude which I set to auto update

"Latitude"? How can I verify that it doesn't affect me

Latitude comes with Google Maps, its basically a location sharing feature. If you press the menu button in google maps you can click on latitude, then menu button again -> settings, and change from 'Detect Automatically' to 'Manual'
If you don't know what it is I doubt you actually have it enabled anyway, so it could be some weather widget maybe?

I checked and my menu reads as "Join Latitude" which means I have not enabled it in the first place (I guess so).
I'm using Beautiful widget for weather service so not sure whether that is the culprit.
I wish there is more visibility for this .
Thanks for your explanations .

Btw I tried the Supercharger script, and it has doubled my battery life
(You need root)
I chose options 1,6,17

Here it happened again today early morning!!

May be due to the "Green Power" application. I checked before and if I switch on the WiFi it is continues without any problem.
I too hope for the same as you. Annoying bug .

I have the very same problem. The phone battery goes from 100% to 66-64 over the night...showing that the Cell standby and Display has drained the most of the %...

How can I track down my battery drain?

Leaving my OP in place, but I have rewritten the description with much more detail and pics here
http://forum.xda-developers.com/showthread.php?p=25401417#post25401417
I suggest skipping to there.
I am looking for general tips here. E.g., not asking you to diagnose my specific problem so much as give me ideas of what else to check or try.
Lately I have had unexplained (to me) battery drain. Yesterday I lost about 25 percent in an hour while the phone idled. It is not a constant thing, though. I can go an hour and loose 1 percent then loose massive amounts in the next hour.
Now, i have searched, but I have not found anything that applies to me.
I have:
Tried a different radio
Tried a different kernel
Reflashed my rom
Phone is entering deep sleep according to cpu spy
There are no unusual or excessive wake locks according to better battery stats
No apps are using a lot of battery.
I am in a low signal area at work, but putting the phone in airplane mode and dissabling background syn does not stop the drain.
Ideas?

might be your phone is loosing signal? i would check the battery stats in the settings menu to see if you have a poor mobile signal.

I do, and on reflection it is a possible culprit since I added it recently.
Didn't occur to me since it was producing no wakelocks and the battery stats did not showing as using much battery.
I shall turn it off for a bit and see if that helps. (unless there is some other way to test if it is the problem first.) I am off to the search button!

This is from yesterday when i set it down unused for about 90 minutes. The amount of wakes seems liek a lot, but it is similar to what i see when i have far far less drain, so I don't think that is the problem. I didn't get the app list screen, but out should screen as the only major drain with about 2 minutes.
I know it is shows poor signal strength, so immediately after that shot I put it in airplane mode, turned of sync, and rebooted. The battery continued to drain and graph had the exact same slope under those conditions. (Forget to get a pic though.)

System panel paid version with monitoring enabled is the best for tracking apps using CPU.

OK, still working on this.
To recap:
When the screen is off, and no apps are running I sometimes get inexplicable battery drain. This is occurring under conditions when I should be experiencing little or no drain at all. I say this becuase:
The screen is of and no bakground apps are running
the phone is NOT awake and IS entering deep sleep (as confirmed by cpuspy)
there are no unusual kernel or partial wake locks
there are no apps listed as using unexpected ammounts of battery
This is not a universal problem. The phone *often* behaves as expected. I can leave the phone off for an hour and see a 1% or 2% drain, and I am happy with that. However, sometimes, randomly, it goes nuts on my.
This graph from a few weeks ago shows what I mean. Look in the green box. The phone is sleeping, and the screen is off. The graph starts as a flatline, then, all of a sudden, it begins to drop precipitously.
Here is a graph that shows the battery dropping at the same rate whether the phone is awake or sleeping:
I have gone the following to try and narrow the problem down:
Done a completely fresh install of my Rom including a system wipe.
Tried two kernels (the aokp default and several relases of Franco's
Tried a different radio
Activated and installed a new sim card
I have come to suspect that the problem is network related. When the problem starts, sometimes going into airplane mode and back and/or toggling 2g only temporarily fixes the problem.
I suspect that something is happening with my connection to T-Mobile that keeps the network running and draining power. This is pure speculation, but it is all I can think of.
I installed juice defender (which I had not been previously running) and noticed the that, sometimes, it didn't turn of data when it should have. I also noticed the following two things happen:
I do not believe it is a rom problem, since if so, someone else would be reporting this. It might be an app problem, but if so the app is draining battery without a wake lock and while the phone is in deep sleep.
It is not exchange (as was suggested in this thread) since it continues when I ev my exchange account.
I have no idea what else to do or try.
Since it happens at random and takes a while to identify, uninstalling one app at a time to test for that could easily take months to narrow down a misbehaving app.
I know it is not a hardware issue since last month I got this:
That was with AOKP and Franco (earlier versions obviously)
I have google searched till my fingers bleed.
I am a long way form being an expert, and I suspect I may have overlooked something obvious.
Please, any thoughts??

Damn you definitely have a major issue and I don't know what it could be. But when my phone sleeps itstays dead flat with no awake bars, and drops 1% every 3 hours.

1. Calibrate battery
2. If you really wanna find the problem, install the rom with no mods or apps and run it and see if it still happens. Then add back each mod/app one at a time

While I appreciate your effort, this is remarkable unhelpful for the following reasons:
1. "calibrating" the battery is a myth and doesn't actually do something. Even if it did, it would not explain the symptoms I have described. I have been around xda long enough to know it is the knee-jerk reaction to any battery question, but it is not relevant here.
2. Since the problem occurs at random, and sometimes takes hours to show up, (For instance, last night I charged to full and tried to catch it happening. For 4 hours nothing happened, it behaved perfectly. Then I went to bed and it immediately started to fall and was dead by morning) and since I have over 100 apps, your suggestion could easily take *over a year* to follow. Believe me, I have thought about it, but I started this thread hoping for ideas that would allow me to avoid it.
Here is that chart for last night.
I had about 1 hour and 30 minutes screen on time with 65% left when I went to bed. When I woke up, phone was dead.

Mine often does that. But sometimes it doesn't. It is the fact that it happens seemingly at random that makes it so annoying and hard to track down.

I would replace the battery
One thing you haven't rulled out is that the battery itself is bad.
Have a friend you could swap with for a day, or at least long enough to see if the problem follows? If your battery drops on their phone that is also a good indication.

The thought has occurred to me, but unfortunately, no, I don't have a friend I can swap with. And really, since I have had the phone less than 3 months, the battery *shouldn't* be bad, but yeah, defective products happen.
If I cannot find any other cause I will likely order a new battery and see if that fixes it.

1. yes battery calibration does make a difference.
2. ok, so an app can't run a process at random? especially when you have "over 100 apps"? Run the rom stock and see if it still happens, or even run the stock rom/kernel. if you don't want to try this then why are you asking for suggestions? christ

You are incorrect. But, in any case, I DID calibrate the battery just to cover bases in the case that I was wrong.

We'll of course it can. That is kinda my point. If I go one app at a time waiting for it to "run a process at random" I am talking literally MONTHS of testing. I would have to wait many hours, if not days after installing or uninstalling an app to be sure whether or not it made a difference, then move on the the next. This is simply not an option. I started this thread in hopes that a realistic and doable solution might exist that I was unaware of.

I am asking because there may be a solution that I am unaware of that doesn't require me to put my entire life on hold for months. It is possible that there is no such solution, but I asked in case there was one.
Sorry to have put you out so much.

You mentioned you recently installed exchange sync. Did turning off sync remedy this or have you not tried disabling all sync features?
One other thing to check is the background data usage of your apps. You'd find this under 'data usage' and make sure you enable the wifi tab so you can see data usage on wifi.

My battery also drains at a rate similar to yours however I'm on the CDMA version. Hopefully you can figure out what's going on with yours.

[Q] Why is my phone not going into deep sleep?

For some reason my M9 doesn't want to go into deep sleep much. Out of the 1 hour I have it off the charger, only 2 minutes were in deep sleep. I haven't used the phone at all in that 1 hour, so I'm not sure why it wouldn't be sleeping.
Does anyone have this problem or know how to fix it? Thanks

Buy, install, do proper settings, put it into monitoring mode.. then switch of screen and go sleep - in the morning see the activities what were happening during the night monitored..

I've used a very similar app. There are no wake locks. All it says is "Android OS" is using 100% of the screen off battery. Even in the normal HTC battery settings, android OS is using 100%. Thanks for the help though.

System Panel is neither similar nor showing you those funny wakelocks..
It thoroughly informs you about CPU usage last night..

Thanks, but all those apps are the same. They can only get a certain amount of info from the core system. There are apps that do the exact same thing for free, which is what I use.
As an update to my problem, rebooting the phone and clearing cache seemed to have solved the issue for now.

If you run out of ideas on how to fix this, I'd say get root, get Xposed, and get Power Nap. Pretty much blocks all wakelocks at night and I see like 1% drain the next morning.

Wait...xposed works on 64bit phones? Wow I've been missing out for nothing lol.

Yes, but make sure you use the xposed arm64 file.

Here's the zip you want xposed-sdk21-arm64.zip
And you also need the alpha installer.

[POSSIBLE FIXES] Battery drain 5.1.1

Ever since updating to new Android 5.1.1 I'm having sudden battery drains while on stand by it will often start to warm up and I'll would see a drop in 20% battery in like 5 - 10 mins. And reboot fixes this. But this has been happening for a few days. Its not the WiFi as I have toggled the WiFi off the watch and locations are also off. I have done am factory reset a few times but no use. Any ideas? Or is it possible to reflash the update similar how you can do on android devices via adb?
POSSIBLE FIXES/ SOLUTIONS
I have summarised possible fixes and solutions to the battery drain
1. Uninstall Battery stats app
2. Re install android wear using Sony PC Companion (this worked for me)
3. Disable Google fit (credit to @maniusng)
4. Install previous version of android wear companion app
5. Fix by @Bender_0
Bender_0 said:
My fix:
I think I stopped battery drains, but not discussed in the XDA option.
Settings> Wi-Fi Settings> Wi-Fi Disable
And then in Wi-Fi settings> Advanced> Energy Saving 15 minutes.

EDIT: POSSIBLE ROOT OF PROBLEM
after doing loads of testing i think i may have found the cause. its the WiFi and its drivers because i have noticed that when my phone gets disconnected and then reconnected later on, during the battery cycle i will have a drain. and if i dont allow my watch to loose connection with my phone and then i would not experience battery drain during that battery cycle.

Try turn off Cloud sync on Android wear app on the phone if you didn't do that. Maybe this is the problem.

Mine has been draining too, cloud on or off

I had this too. The last 20% drained very quick during night in a way it never did before

Had similar issues this weekend. Even tried to use it during a half marathon run and the battery died on me during the race. Even the day before the watch just died on me after maybe 4-5 hours.
Haven't tried disabling cloud sync yet, but have turned off Location and Wifi for now. I also uninstalled a few apps I really wasn't using just in case in the background they were draining battery (even if the battery usage monitor wasn't listing specific apps.) The other thing I did was change back to a stock watch face in case the one I was using was draining battery (it was Minimal and Elegant.) Drain has slowed down, so I need to keep playing around with settings.
My guess is it's tied to apps that weren't ready for the 5.1.1 update, so we'll see if I can determine what I was using that started the drain.

yes checked its off in my phone as well

there is a similar thread of a user seeing what is causing the battery drain and he found out that it is "wear battery stats" as it kept waking the watch. i have unistalled this app and the watch battery seems to be ok. after another battery cycle ill let you know what happens

After receiving the update and it killing my battery from 100% to dead in 6 hrs I charged the battery over night took it off charge at 11 am yesterday and at 4 today I'm at 3 % which is 29 hrs with sync and wi-fi on and I'm using Wear battery stats.The funny thing is my battery before the update would not last even close to what I just got.

Are you using wake screen by wrist movement? It could be a bug in the accelerometer

Yes I do.My battery died around 6:30 I'm going to charge it and see what happens.

Have tried the below all while Never having the phone and watch apart more than 2-3 meters:
Wifi off , cloudsync on
Wifi off cloudsync off
wifi off, clousdync off, gestures off
wifi off, clousdync off, gestures off, GPS off
wifi off, clousdync off, gestures off, GPS off + Factory reset (twice)
wifi off, clousdync off, gestures off, GPS off + Factory reset (twice), Cinema Mode
The problem still keeps coming back.
As far as i can tell nothing i do is triggering it.
My next thing to try is to uninstall anything that i can that has a wear app in it, though that's going to be very annoying.

I think most off problems are related to Cloud sync and turning it off will be good for battery. But there is something alse that is draining battery. I had problem with some watchfaces and had to uninstall them day after updating Android wear to 5.1.1. They were killing my watch. Now I am still looking what is draining battery. I'll post my results when I am finished.

Has somebody Google Fit installed and no battery life problems?

I think it could be due to the fact that I have greenifyed the watch faces and watch apps on my phone. I de greenifyed them and I'm gonna check out the battery and keep it updated.

It looks like there is a version that ships with the watch by default.... Maybe that's the issue..?

I see no difference but use it like I always have no WiFi

Same here.. I have wear battery stats installed on my computer and I've seen sharp spikes with the battery, up to a 20% drain, that's from 2.33% to 3%. I've done the following with the same issue happening:
1. Went into recovery to clear cache
2. Factory Reset from Watch
3. Removed Wear Mini Launcher
4. Removed all additional watch faces
At first it seemed like it was back to normal.. but then I would get another sharp spike... and at times when powered back up from being dead it would act like the cache was cleared and would start the updating applications before the watch would fully start up. So I went ahead (out of anger) and did the following:
1. Removed all unnecessary applications (Stay Lit Wear was one of them.. possible suspect)
2. Reimaged with Sony PC Compainion 2 (Watch was initially upgraded through ADB)
3. Setup the Watch.
4. Uninstalled updates to Google Play Services on my Phone and reinstalled them back on the phone (thus disconnecting the watch... forcing me to.... )
5. Factory Reset the Watch again.
6. Now that I'm back up and running it seems that my battery is lasting a lot longer... at a drain rate of 1.88%.
Crossing my fingers something in there fixed my issue, and possibly helps someone else.

even after uninstalling wear battery stats, still getting sudden battery drains on idle ambient mode in 10 mins there was a drop of over 20% and it still warms up a lot. I am going to reflash using Sony pc companion.

I hope you guy with battery problem figure it out.Mine is the best It's ever been.

Crazy Android System ?!

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.
