I have a weird battery drain problem...(Bell I337M, latest firmware)
I realized mid-morning that I was dropping battery a LOT faster than I normally do. I don't use my phone much at work so after the course of a work day I'm usually left with around 85% battery remaining. Today, however, my battery dropped all the way down to just over 40%.
I checked the battery stats and saw that Android System was the next highest source of battery usage - with a "stay awake" time of over 12 hours so far. I installed BetterBatteryStats and it points to an Android System process called GCM_LIB holding the wakelock 100% of the time. My phone has not once dropped into deep sleep.
I think this may be the Google Cloud Messaging service, so I tried investigating every avenue I could. I've rebooted three times. I've removed every single account on my phone. I've stopped every push or polling application. GCM_LIB continues to hold the wakelock.
Any ideas? I really don't want to have to wipe the phone if I don't have to, I have everything configured just the way I want it to be.

I had the android system drain when I used google edition roms but I fixed it by adding a few build.prop entries to make the phone sleep better. I didn't have this issue with stock touchwiz roms tho
Deeper Sleep / Better Battery Life

Hi, some of our users said this.
As you can see from this screen: https://plus.google.com/communities/112636044705492129107 they have the same problem of you.
Have you found a solution?
GCM LIB is deprecated as per the GCM website, it has been superseded by GCM Server and GCM Client. Please use the GoogleCloudMessaging API instead of the GCM client helper library. The GCM server helper library is still valid.
There are a number of open bugs against GCM_LIB, including this one and I doubt they will be addressed.
Some of you may have noticed that battery life on this phone can be both unbelievable and mediocre. I've been trying to figure out what can trigger and cause mediocre performance and I'm at a loss. The problem is, there doesn't appear to be a smoking gun. No obvious wake locks. No rogue Apps. I have Carrier IQ disabled by System Tuner. Google Now is off. What I'm running right now is pretty bare bones. And the kicker is my phone is sleeping, as can be seen in the shots below. The vast majority of the time my phone was off the charger it was in deep sleep mode.
I noticed my phone in excessive drain mode Saturday so I let it run over night and into the next day, so that BBS and GSam could pick up as much data as possible, including sitting idle overnight and very little use throughout yesterday.
Here are some shots to show the story. The graph, which is definitely steeper than when idle drain is normal, which resulted in idle drain of about 6% per hour. Also as can be seen in these shots, there is not a wakelock problem. Deep sleep shows as 12 hours 38 minutes, Awake time of 1 hour 8 minutes, and screen on time of 1 hour. So, my phone was only "awake" for 8 minutes when the screen was off out of almost 14 hours according to BBS.
I did notice and oddity here though. BBS listed the unplugged status as 13 hours 47 minutes, while the phone's battery meter listed it at 12 hours 13 minutes.
Attached are the shots I took at 19%, as well as a final battery meter shot after charging the phone to full while powered off and restarting, where it's been purring like a kitten in deep sleep.
Part of me is beginning to believe there is a bug with the battery gauge. What do you guys think is going on?
Try clearing data for google play services,google services framework and playsore than reboot and check if things changed.
And i would recommend uninstall the updates related to those apps and let them update itself again.

Done. Although I won't know if any attempts to resolve the issue have worked until the idle drain triggers again (or doesn't).
Thanks for the advice.
Well unfortunately that didn't solve the issue. The heavy deep sleep drain again triggered after a bit over one full day. I charged to full last night and let sit over night where it drained 6% per hour with no obvious culprit. Anyone else have any suggestions?
It seem that your signal is week, did you get stable signal and have you tried airplane mode, to find out how much battery drain in this mode?
Also, did you disable LG MLT? This is a massive app from LG, can consumed about 150 MB RAM.
This might sound boneheaded, but what about just resetting the phone. Maybe some system app is causing some type of memory leak and thus draining your battery. Also disable wifi when you're not using it.
I don't think it's signal related. I get an excellent signal at work and the idle drain still occurs. Also, it happens whether wifi is on or not. I have not disabled MLT, as I'm not concerned about RAM, just running processes. Rebooting the phone eliminates the issue, so something is obviously getting hung. The really odd thing is I was draining 6%/hr overnight, all while the phone was in deep sleep, yet my top battery consuming category was the screen at 35%, with just 1 hour of screen on time of 10 hours off the charger. If something was cranking in Android System that caused 40% drain overnight I would have expected Android System to be higher. It doesn't make any sense.
I may just have to factory reset.
My battery's been great until couple of days ago when I turned on GPS and Voice Notification (for speaking out names when phone call/message comes in). After I noticed the abnormal battery drain, I turned off those two options, because that's the only thing I did differently before noticing the drain. However, that didn't help... yet. I needed to do a reboot and battery's been fine again. Not sure if those two were the actual culprit, or just coincidence.
Have you changed any settings right before you noticed the drain? Just a thought.
had the same issue., wakelock detector, BBS, GSAM nothing could show what was eating the battery. i use mobile browsing a lot and almost 8/10 times this battery drain was happening with chrome , chrome beta and firefox browsers.
Only thing thats helping me is the Greenify app . Greenified the chrome and firefox and almost all the cloud apps and the battery is now much much better.
still ...IT IS AN PROBLEM to be found..
To provide a bit more info on this, attached is a pic of my reboot a couple hours ago (marked by the thin white vertical line). The change in the slope of the drainage line is drastic. Also, notice the small hump after the reboot? The line actually increased a bit, fell, then flat lined. More and more I'm beginning to suspect the battery gauge, but I just don't know.

I have the same situation after charging. Even in"deep sleep" it would chew through the battery. Now I just reboot the phone after charging and it plays nice. The gerbil on the wheel seems to take a break and rest.
To all who have excessive battery drain, did you charge your phone while it is on or off?
Some where in this forum (if not mistaken), I read that there is a bug while charging G2 when it is on. You should reboot your phone after it is fully charged otherwise you will experience excessive battery drain.
Mine always charged it while it is off and never had problem with battery life.
i got the same issue which is very annoying, have over 85% deep sleep, no wake lock, battery draining like crazy, and it happens randomly. I wonder if factory rest fixes the problem, or hardware issue
i have done a bit testing for this random drain,
with mobile signal on ==> huge drain
without mobile signal on and only phone signal ==> huge drain
airplane mode ==> no drain
so i believe it is a bug within the phone software, actually sometimes the random drain started after a phone call
I've been getting the drain too in the past few days. Last time i could fix it by factory resetting, but obviously I don't feel like doing that once per month. What I do know is that flashing another stock ROM (kdz) without factory resetting doesn't fix it. However last night I figured i'd try disabling WiFi (kept it on during the night until now) and I only drained 1% in 5 hours, down from 3% per hour. Perhaps this bug is related to WiFi.
Have you disabled LG MLT? It acts like CIQ for internal LG purposes. I have personally seen it cause mass wakelock in unexplained situations. If I leave everything on overnight under 95% battery, I will get around a 3% drain in about 7 hours. Pretty normal. The first 5% on these batteries seem magical. At 100%, with everything on, I wake to 100%.
Yup, frozen in TiBu. Will be factory resetting however when I get home as GSAM grabbed my attention. Never were system things so high up the list when i had no drain.

I been struggling with this since I got the phone (almost a month now). I've done all the usual:
Removing bloat
Disabled CIQ
Disabled Google Now, Location, GPS
and I have the same apps as my Nexus 5
Just last night I realized that this battery drain only happens after taking it off the charger. This got me to add the word "charging" in my search and I found this thread.
Is this hardware related, or would a custom ROM resolve this? I have the AT&T version.
Ok and which stock rom does not do that?

Guys could you write which stock rom does this wakelocks for you so we could eliminate corrupt firmwares?
For example I experience these wakelocks on latest F international version.
I have a new Samsung S4. Trying to learn how best to configure it to minimise battery usage and to ensure I don't install apps that eat battery. There's nothing wrong with it, battery usage is fine, just trying to get the best out of it; whilst keeping as much functionality as possible without having to constantly turn things on and off. I'm trying to avoid rooting it.
As a starting point, I'm checking usage overnight, when blocking mode and power saving are on, with wi-fi and data off; but with the alarm clock set.
I have an i-onik 7.85" tablet on Android 4.2.2 - with a deep sleep battery saver app set to slumberer ("always deep sleep when screen off") it only uses about 2% of battery overnight - the battery currently holds about 3600 mAh - so that 3% equates to 108mAh.
First time I tested my Samsung S4 (the european LTE version 9505), (actually I think I had wifi, data, location setting turned on and power saving turned off), it used 4% battery overnight. Not bad, 4% of 2600 mAh is 104 mAh. Still I thought I might do better. I tried the deep sleep app on slumberer but inexplicably the usage then jumped to 12% (whereas it at least halves battery usage on my tablet). I've since un-installed deep sleep battery saver and started turning off wi-fi, data, and turning on power saving - so I'd expect it to use 4% or less battery overnight.
The actual battery usage instead increased to around 9% to 12% - although the settings used might have varied.
Three nights ago I made sure that all apps were closed, and everything turned off as above - battery usage overnight was still 9%. I used WakeLock Detector and found that a Morrisons App was causing wakelocks. I uninstalled that, and the next night the battery usages was down to 6% with much fewer wakelocks. Still not as good as before though.
I then found there were wakelocks due hotmail and gmail sync - hotmail I changed from push sync to sync every 4 hours, gmail I changed from hourly sync to manual sync and I also turned off master sync. I also turned off location setting. That cleared the wakelocks for these apps, but battery usage last night had increased to 9%.
So, despite the same settings and less wakelocks (and it was in deep sleep all night except for 16 minutes), battery usage increased from 6% to 9% - still no where near the 4% I had at the start despite making various changes that should reduce battery consumption.
The only significant wakelocks last night were:
com.domobile.applock (via alarmManager) awake 35s giving 992 cpu wakelocks
com.google.android.google (google app) 7 wakeups
Can anyone think of any cause for increased battery usage from 6% to 9% despite more time in deepsleep, less wakelocks (other than the 2 above but there were many more wakelocks the night before lasting several minutes) and location setting turned off. I wonder about starting again from a factory reset ... NB every night before going to bed I've rebooted the phone, and charged it to between 90% and 96% and it's been tested over the same period of time. Is it normal for battery usage when the phone is sleeping to vary so much?
Charging the battery inconsistently might lower the battery life. And letting it discharge to much does the same. I generally avoid letting it go under 50% and unplugging it before 100%.
I don't know what causes your issues, but if you want full control over your phone, you will have to root.
I also had 2% drain over night at some point, but now I have 4%. But this may also be rom related.
Thanks. I'm on stock ROM. I have rooted other devices but then find some apps don't work, and of course I want to maintain my warranty.
Each day my battery is generally dropping to about 30% at which point I charge it up to between 90% and 95% before turning turning most things off ready for bed.
At some point I may leave it plugged in overnight instead - is that a bad thing?
What do you mean by charging inconsistently? Sometimes my battery may be around 50% though more often around 30% when I start it charging.

By charging inconsistently I mean exactly what you said. You charge between 90 and 95% generally, instead of leaving it to charge 100%.
Somebody said that if you live in the EU you will not lose your consumer rights. I guess that includes the right to have your phone repaired because it is in warranty. Other people have reported that the phone service accepted and repaired their phone even though it had knox flag 0x1.
There isn't much you can do on stock unrooted roms in order to reduce battery consumption.
You battery drain is probably caused by weak signal strength. Having bad signal uses more battery. The screen and the phone radio use the most power on the phone. If you put our phone in airplane mode there should be almost no battery loss. If everything is turned off.
On my old device I used to put in airplane mode during the night. I had 0% drain over night in airplane mode.

Thanks - that's a good point about signal - my mobile signal and wi-fi signal does seem to vary, so that could contribute to fluctuating battery usage. I decided to test that by using airplane mode and have started charging to 100% on your advice. Unfortunately when trying to dismiss the prompt to upgrade to lollipop, I accidentally started the upgrade, with no way to cancel it. (For me, lollipop really seems a downgrade, I've lost a lot of functionality I used all the time in KitKat).
The bad news it that on lollipop overnight last night, despite using power saving mode and airplane mode, and basically everything else off including sync, it lost 7% of battery.
So I decided to do a factory reset, thinking it would go back to KitKat - but it didn't - it stayed on lollipop. It did give me the option to choose which extra apps to install (including some Samsung ones) - I declined to install any extra apps, and also turned off automatic app updates - I then turned off sync, backup and anything else that I thought might eat battery - leaving the phone with the most basic set up possible. I've not since installed any apps except Talk2Go.
The good news it that since the "factory reset" to lollipop, I've tested it for two periods of 4.5 hours on airplane mode, everything off, and I did not turn on power saving mode. The battery lost less than 1% - in fact for my last test it stayed at 100%. So either the reset fixed battery loss on lollipop, or the power saving mode was actually causing battery loss!
I'll investigate that and report back for the benefit of other users. I'll then gradually update my settings and see what, if anything causes battery usage to increase when on airplane mode. Of course it's also possible that battery usage might increase without changing anything, as per some reports from those upgraded to Lollipop - if so I'll report on that - and confirm if a reset seems fixes it.
Lollipop is supposed to have a battery saver mode - but it seems to be missing in the stock OTA update to S4 - does anyone know how to use this mode? It sounds better than Samsung's own power saving mode (especially since that might actually be causing battery drain rather than saving battery!)

Samsung probably replaced the stock lollipop battery saver with their own battery saver.
You could return to kitkat by flashing via Odin. Doing so will not give you knox status 0x1 and you don't even need root.
On second thought, you have the new bootloader so you probably won't be able to do it without tripping knox..
From what I saw, battery saver changes only the minimum screen brightness to a lower value than normal and it changes the CPU governor to a more battery friendly one.
This is what I observed on the GPE rom battery saver mode.
Testing continues - for the first few nights battery drain was less than 2% on airplane mode, but it wasn't repeated last night. It drained 9% with exactly the same settings (ie everything off except the alarm clock, no foreground processes running and airplane mode on).
I've installed a few apps - one from TalkTalk, one from Three Mobile, a terminal emulator and wakelocks detector. So have now uinstalled the first 2 to see if they are causing the drain - BUT I suspect it's a bug in this release of Android Lollipop.

Many people have problems with the stock lollipop. Samsung messed up.
It might also be the battery. I have my phone since november. My battery used to drain 2% over night. Now it drains 4% over night. Basically it drains very fast to 96%, from there it drains normaly, depending on the usage. This happens on every rom I tried and with even the most battery oriented settings.
You seem to be using applock. If you don't need it you can delete it and get rid of a few wakelocks.
Hi guys,
I have been having an issue with my Motorola X Play (UK Single Sim) I have only owned it for a few months from new.... The battery is draining fast and I can see in the battery stats that it's not sleeping, otherwise the battery usage page shows nothing of interest, apart from perhaps Mobile Standby which is quite high, above the screen but the signal bar is all green...
I rooted my phone to better find out what was causing these issues, otherwise stock Marshmallow. Unfortunately Motorola now are not interested as they say my phone is rooted and now has no warranty - useless idiots!
Using GS Sam battery monitor (rooted) I can see that the following is keeping the phone awake, no other app is.
48.3% of battery consumed by Kernel (Android OS)
Keep awake over 2 hours
CPU usage 59m 53s

I have tried safe mode but it appears to be the same, I have hardly any apps installed apart from Facebook and Facebook messenger and I have even tried it without them...
I have tried turning off/on WiFi / Location / GPS is now disabled. WiFi Scanning is off. Restarts make no difference... I have even done a factory reset about a month ago.
Any ideas, this phone is having the same battery life or less than my Nexus 5 which had a much smaller battery...
Many thanks
here's a way to avoid it http://forum.xda-developers.com/galaxy-s2/help/google-c2dm-checkin-services-t1321520
i'll update if i find anything else.
don't tell them your device is rooted. if you go to service center just re-lock the bootloader and its back to normal.[it won't get your warranty back but they don't check that much]
can you post a screenshot of gs sam.
1 - Install BetterBatteryStats (BBS) - this will give you detailed information on what is draining your battery. Get it from XDA v2.2.0.0B6 - this gives you the detailed breakdown in the UI that you are after, the google play version doesn't do it in the UI (older version).
Get baseline results (charge it full, don't touch it for 5-6 hours) I like to do this while sleeping.
2 - Install Greenify (you don't need the Xposed module if you don't want to fiddle with that yet, alto I highly recommend it) set the working mode to root. If applications are still not sleeping, add the widget and force sleep everything before you turn off your screen
Get BBS results (do the 5-6 hours while sleeping) - improved?
3 - Install Naptime from the google play store (by Fransico Franco)
Get BBS results - improved?
Getting anal about battery usage?
4- Read up on Amplify - this yielded even more results for me. But this can take a bit of work to get right. There's a lot of great threads on XDA for setting this up.
5 -Smart network - allows you to control data, networks, wifi, bluetooh, nfc, gps on/off with a ton of great features for auto. management.
I have all the above and yield a 0.4%/hr drain on stand by (see signature for phone build).
Amplify is a god sent app. It has been 4 hours now, and I have been using whatsapp on and off (about 20 seconds each time) and I still have 97% left in the tank.

Facebook app has been known to cause serious battery drain in the past. Uninstall it and test again.
In 99% of the cases it is caused by an app. Try to find out which one is causing the drain.
Hi all,
Sorry for the delay and thanks for the replies. I performed a factory reset again, after clearing the cache etc, the same as I did last time. The only difference is I then installed Android 6.0.1
The battery drain has now gone. I didn't perform a restore of apps etc, and the only apps I have installed so far in addition have been Facebook and Facebook messenger but I have found these have had no effect at all on the battery drain. I haven't even updated the stock apps (apart from the security ones).
I now get two days of use easy. It also seems to be running slightly faster. I will update apps one by one, over the course of a few days to make sure nothing causes it again...
http://forum.xda-developers.com/android/general/guide-extreme-battery-life-t3095884
I use this guide, works really great to limit wake locks.
And I don't use Fb app but use the browser instead, battery lasts easily two days of "heavy" usage !
I found the problem, or at least a major bug. Whenever you cast to Google Chromecast Audio and then stop casting completely there is a massive wakelock until you next restart the phone. My phone was awake all night and down to 20% battery life. Android OS takes a massive portion of the battery life and under keep awake stats it's 9 hours +. It seems that when it says disconnected it is not. A major bug! I'll try and report it using Google's bug reporter...

not even Doze could kill it? perhaps you could try Servicely and see if it could stop the thing from running.

Nope, Doze had no affect at all but it should be as it was sitting stationary overnight - normally the drain overnight is a few percent at the most, last night it was around 65% and I was left with 20% in the morning and this was I think the first time I had used Google Chromecast Audio since the factory reset with great battery life up to last night... I could try Servicely but I am not sure on the service to kill and I'd like to keep it 100% stock for now so I can help out Google to fix the bug (or Motorola if they bother)... What a pain as I just bought 4x Google Chromecast Audios!!
I have reported it here in the Android bug tracker, feel free to comment / star the issue to bring it to Google's attention.

However I am not sure if this is a Motorola Issue or a Google Marshmallow / Chromecast issue?? Motorola support have been very unhelpful so no luck if that is the case...
If anyone else with Chromecast Audio could confirm the bug that would be great.
Thanks
Laurence
There's a post on reddit about battery drain with chromecast audio about a year ago, not sure if it's the same issue though.

If you bought it brand new just go back to the shop for replacement

My Essential PH 1 is draining a lot.
Phone idle is taking most power with approximately 17%. Screenshots attached.
Can you please advise if this is normal and ways to minimize battery drain ?

Are you showing off? because those are amazing numbers. You're on track for 35 hours! I get around 26. Your bigger killer is What's App, but that's expected for a Facebook app. 17% for idle means your phone is on and doing nothing 17% of the time.

Nope I am not showing off, I think i am having huge drains when I am asleep. Most of the time in that graph is idle time so i am thinking it should be better ?
Again I moved recently to droid from iOS so i am unsure of the droid power management baselines.

Cool. I didn't mean to seem mean, but those are good numbers. If your phone is on, and you have push notifications (pretty much every social media app, phone, sms, etc.) you're going to have drain. Even if the phone was off, the battery would drain somewhat. But you have What's App and other chat apps, so that'll use battery, even if your asleep, the phone isn't. It's the only way you would be able to receive calls, text, updates, etc.
That 17% looks steep, but it's all relative to a small screen. over the span of 20 hours and you still have almost 50% battery, especially with "free" apps that are basically advertising engines pushing ads at your every minute. Having Phone Idle at the top is not a bad thing, it just means you don't use your phone as much as you use What's App.
1% per hour is good, better than our S8 even
I had enabled "Cellular data always active" and it chewed through my battery life. I turned it off and can now last 1.5 days on a charge.
My phone is draining 12% overnight. And phone idle is top of the list. What does this phone idle do? There was a random night where the phone only dropped 1%. But most nights, it's draining around 10% with phone idle at the top.
Update: setting wifi to not stay on while phone is sleeping seems to fix the drain issue.

Does disabling it affect receiving messages that rely on mobile data such as WhatsApp?
Where is the "cellular data always active" setting? I don't see it. Have not updated to run Oreo.
My battery was dropping from 95% to 5% overnight. Did a factory reset which helped, but I'm still losing 17-20% overnight. Seems odd to me on a brand new phone, but I have never owned an Android before. I have blocked notifications and location services from nearly all of my apps. Any advice other than what has already been posted?
If your losing that much overnight it's probably a bad app.
I don't use it, but have read that the Facebook messenger is good for that. As in eating up a battery overnight.

I can promise you that that's not normal, especially for this phone. Overnight battery loss is minimal, 15 hours of idle with a 10% drain is what I'm getting. That's pretty amazing. I'd check your apps and ask the general android forums for advice. I also bet there is a rogue app draining you juice. chat and social media apps with all their pushed content and friend updates are huge battery killers.
Install accu battery ,charger to full last thing at night ,don't touch through night ,then see what's draining battery ,mine drains by about 2/3% through 8/9 hrs at night

It's under developer options settings. I have mine always active without draining my battery noticeable.
The social media apps such as snapchat, facebook, twitter, etc... are the ones draining your battery while your phone is idle so you need to disable their background data running.

The option to Cellular Data Always Active is on the Developer Hidden Menu. If you have it enabled you should be able to turn it off.
Thanks to all for the replies. I thought that restoring factory settings had helped somewhat, but it turns out not to have. Battery has just depleted from 100% to 67% in 3 hours while the phone has sat idle.
The only social media apps I have installed are FB and Whatapp. Notifications for both are turned off. Location services for all apps are also off. The only apps I have installed have been download from the Play Store and have run on my previous phones without causing any trouble. Those who replied all suspect a bad app, so I have installed ACCU Battery as suggested to see if I can nail it down.
Thanks again for the responses.
Try this for one night. Right before bed....
1. Turn OFF WiFi
2. Reboot phone
3. Leave WiFi off after reboot
There is a bug in Google Play Services that affects many people on many different phone types since the November updates.
When on wifi, in certain circumstances (many theories on what the actually trigger is) it will cause Google Play Services to run non stop on certain WiFi networks causing huge battery drain.
In this particular scenario, turning off Wifi does not stop the battery drain. The phone has to be reboot.
I don't know if that is what you are experiencing, as you didn't say if it was an app or system taking so much battery, but I thought I would mention it in case it helps.

Why don't you look in settings/battery and see what is using the highest percentage of the battery?
Have looked in Settings/Battery, but am not seeing anything there that diagnoses the problem to my understanding. Highest use shown is Chrome (4%), then Screen (4%) then Google Play services (3%). ACCU Battery app shows the same. Battery is still losing 10-12% of its charge per hour while the phone is idle.
Have sent a message to Essential support to ask if they know anything about a bug in Google Play services causing battery drain. They have so far only suggested rebooting to safe mode and doing the reset to factory settings. Hasn't helped.
Will try shutting wifi off, rebooting and leaving wifi off tonight as suggested. Not really sure where to go from there even if that does save the battery, as a phone that has its battery drained just by being on wifi is useless to me.
If turning off WiFi and rebooting helps reduce system cpu usage, it is a bug in the software and not the phone. I can reproduce that specific issue on my pixel 2 and Samsung Galaxy s8, too....
If the CPU usage isn't from system, though, or turning WiFi off and rebooting doesn't help then you obviously have a completely different issue and need to troubleshoot further.

Update:. Nothing Essential support has suggested has helped. Battery is draining to zero overnight while phone is idle both when connected to wifi and when not.
Upon learning that I had purchased the phone at a Telus store in Canada, Essential have said that they can't help me further and have referred me to the store for assistance. I'm disappointed in the lack of support from Essential.
