Solution to large battery drain when idle

I have found the solution for MY large battery drain:
The problem has been, that my phone used 5% of battery per hour when it’s merely lying around. The battery graph was a straight, quickly decreasing line. So the culprit was not something that happend from time to time but always.
One very disturbing thing: The indicators below the battery graph shows when phone, Wifi and the screen were on. In additions it shows when the phone has been awake.
Even if the screen was off and I did not touch the phone, the „Awake“ indicator constantly showed every minute for a very short time. So the phone never went to sleep, it woke up constantly all the time. Sorry, unfortunately I don’t have a screen capture for this.
Deactivating automatic updates for applications and setting the Emails to sync never didn’t help. I even erased all the Samsung crapware from the system folder, but to no use. The battery died after one day of not doing anything with the phone.
Then I deactivated syncing of the contacts and the calendar for my WindowsLive-Exchange account and the battery drain stopped. I now have less than 1% per hour (see screenshot) when the phone is simply lying around.
So, for me the culprit is the syncing for contacts and calender via Exchange. Unfortunately there is no option to set the sync interval for these.
- Anyone can reproduce this issue?
- Is this just a problem with WindowsLive Exchange or does this happen with other Exchange accounts too?
- Is there a possibility to set the sync interval for contacts and calendar (somehow, maybe via a config file)?

There seems to be something seriously different if not broken in GB 2.3.3. Apps that work perfectly fine in Froyo are keeping GB 2.3.3 from going to sleep. I've isolated several apps that either keep the screen from shutting off or keep the device constantly awake even when it it's no longer running/cached/screen is off. And, these are programs that work perfectly fine in Froyo and do not cause idle drain. Wonder if this is something 2.3.4 addresses...

I have frozen:
social hub, email (i use another one), and few more programs that I dont use but noticed that they stay on without any reason,
if 3G or wifi is ON battery drain is prery bad, I guess this is a bug in 2.3.3 as cmd512 said.
Last night I turned off wifi and 3g and made sure that wifi share + manager are off (they can be turned off easily if u untick "use wifi" in location settings menu)
so with everything off for 7 hours sleep (dont rly need my phone while sleeping) battery was down 2% only :O
the moment I turn on 3G Android OS use jumps to the skies :X

Hmmm..it could be. I will try this also. First I just take the contacts out, because that is not so necessary for me. Calendar is pretty necessary for me and emails are a must. If I have to take the calendar out, then so be it. I will manually sync it once a week then.

By the way, I just noticed that with my gmail account the sync icon is constant in the calendar.
Now when I unchecked it and checked back it went away after a while.
I am not sure if it was sycning all the time without luck. Lets see.

I think calendar synch is on of the probleme. With calendar sync my phone drain 5% per hour in idle mode without 1% by one or two hours.

It's quite strange that there's quite a lot of these threads now all saying about how bad the battery is but I'm amazed by how good the battery is. I don't use my phone a huge amount especially at work and when I get home I use it for a quick web browse and the occasional text message and phone call. Most days I will still have 80% or more left by 23:30 having been on since 07:15. Today I checked my phone at 12:30 and the battery had only gone down 1% in just over 5 hours. All I did with it from 07:15 was occasionally take it out of sleep but not unlock it to check for any notifications. Since then I've been using the web (data) for about half hour or so, an hour of music listening and texting and right now I have 77% left after 12.5 hours off charge. Therefore I think my SGSII has the best battery life I could ask for.

Really depends on what apps you have running, as you can see from my original thread on this "Awake all the time during idle" issue:
http://forum.xda-developers.com/showthread.php?t=1094666
But in general, agreed. Once I got rid of that bug, the device has been fantastic with battery life. And, for a stock ROM, that's damn impressive!

I fully agree. Now that I don't have the "wake-up" issue anymore, the battery lifetime is almost as good as the Omnia7 -that's damn impressive for a modern Smartphone with such a hardware!

For me, I turned off my wifi, gps and "my location". And most importantly, my applications are not running when it is on idle. Go to task manager by holding the home folder and click exit all. Or you might try to clear the ram memory.

i have turned off gps, wifi and syncing but still getting battery drains can´t even last for a whole day. But I installed Litening ROM just now and see if this helps . I was on KE2 before flashing custom rom

I have noticed the same issue trying to sync to a exchange 2003 account. It seems that my calendar is syncing either every minute or about every 20 minutes. I also noticed the same issue with my gmail calendar. I have tried two different phones and reset each one several times. The same problem keeps occurring. I may have to download touchdown for email, contacts and calendar. It just sucks because then I will have two calendar applications (one for work and one for home). This is very frustrating.
Are you still having issues with echange calendar sync?

After updating to KE7, I have noticed that every time I receive an exchange email the screen wakes up for a second or two and goes to sleep again.
Didn't occur on previous firmware. Anyone else with this issue and a possible fix?

Is social hub the best solution for IM? I would like to have Yahoo and MSN messengers on always, so should I use another less power hungry client? When people mention calendar synch is it google calendar they're talking about? My google calendar is important for me, so how to optimize it?

Yes, unfortunately. I am now syncing manually with a switch on the homescreen.
I am now hoping for Android 2.3.4 to fix this issue.

Have a look at comment #290:
http://code.google.com/p/android/issues/detail?id=11126#c290

I have an X10i with Jerpelea's CM7 with custom kernel and that had a very annoying deep sleep issue (the phone never went deep sleeping) which caused the battery to drain very quickly, but Temoi19 found out that by disabling automatic time updates and manually selecting the operator, made the phone to deep sleep. So I took a shoot and tried the same trick on my new Galaxy S II and now when idle my phone barely eats power. After over an hour after unplugging I was still at 100%. I don't know if I am just lucky, but it is worth a try

I also have this issue with my sgs2. I looked into the exchange settings and there is the option to change the syncing. It was set to push, I now i changed it to manual and will report back the results tomorrow. The drain in general only occurs when mobile data is enabled here. Didn't try with wifi yet.

You can leave the syncing to push, it's just for the EMails and they're working fine.
I'd propose to disable the calendar and contact sync in Einstellungen -> Konten -> Automatisch synchronisieren

according to the logs if there are no changes in contacts or calendar both will be synced only once per day. so this should not be the issue.

Google Services/Google Play Service/Google Framework Services draining battery

Bear with me. If you are an expert on android maybe you can help me out here. First off, I have researched the crap out of this problem and still been unable to fix it, so YES, I did search before making this thread.
I am on a stock, rooted Verizon Galaxy S4. I have been watching my battery consumption carefully via the integrated battery settings menu, battery stats plus and wakelock detector apps. Mainly, there is a program or set of programs that typically is called "Google Services" that according to the integrated battery menu is consuming anywhere between 20-45% of my battery, sometimes more than the screen on time! My battery life is around 48hrs with 10hrs screen time but that is on the massive zerolemon 7500mah battery which I just bought, so I am not sure if that is above, below or just average (i.e. I have no real standard by which to judge).
Like I said I have read probably every thread about this problem with remedies such as; disable location, turn off google now, turn off google maps reporting, uninstall updates for google play/google play services/google framework settings, turn off google sync etc. I have tried them ALL, none seem to work. I have a feeling the issue is perhaps more in depth and above my head.
It gets more complicated. Although the stock android integrated battery menu reports it as using a massive amount of battery, the other two apps I mentioned above do not even report it, or at least not under a name that I regonize (perhaps that categorize it under a different process?). Under them screen time is by far the highest consumer.
So what to make of this? Is it a false report that the stock integrated android battery menu is reporting, and thus something to disregard? I doubt that because there are many other threads out there of people with the same problem and questions I have. But It's also not like my battery drains within hours. For instance, today I have been off the charge for 12.5hrs, with 3hrs and 40min of screen time and have 63% remaining on the 7500mah zerolemon extended battery.
If you can help, please do. If this is indeed a major drain I would really like to fix it.

Yes that seems to work, but it's not really a "fix" as now I cannot use the location feature of many of my apps. Basically traded one problem for another, albeit lesser one.

I'm still trying to figure it out as since last update (MEA firmware) , my phone is heating a lot.
I had this problem with data connection on, I had this problem in airplane mode, but not strangely with having connection to wifi.
I also observed that google services and android system is consuming most of the battery. earlier when I used to get 8-10% consumption in full use in an hour, now, 8-10 % is consumed within 30 mins.
No tweaks are working. Frozen a bunch of apps but the problem is still there.
Just now I've uninstalled fileexpert HD , as "greenify" told me that since last 20 minutes my phone is on, it has taken 250+ wake locks.
I'm charging my battery to full to check if that solves my problem.
will try to disable location services and report back on the results.

Bump

Have the exact same problem, before the latest firmware my phone had awesome battery life, and now the battery goes from 40% to zero in just a few hours without any app running when I'm sleeping... it's horrible. Same problem with my wife's S4 since the latest update... It absolutely sucks.

[Q] GCM_LIB holding constant wakelock causing bad battery drain

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.

Lollipop battery drain

I got the German 5.0.1
IS it only me or is it general with the battery drain?
Even in Flight Mode, I am losing the battery in a couple of hours

Hello everyone, two days ago i downgrade to kitkat, I decide to re-put Lollipop because I'm documenting on various forums Italian and foreign, and this drain the battery does not have all .... well for my case I installed the GSAM Battery Monitor from Play Store that seems to work well with Lollipop. I left the phone idle and discovered that the deep sleep has never been reached. The phone was always active, even when locked.
GSAM has reported that the app "Unified Daemon (EUR)" was among the top three applications that consume battery.
According to various forums is a preloaded application from Samsung that unifies information like weather across other applications preloaded. I really do not know what good has this application.
I tried to turn it off, and in fact the phone goes into deep sleep with consequent consumption "standard" like KitKat.
The downside of disabling this app is that you lose the weather from the lock screen and through the window of the cover S-view, while the widget on the home seems to work perfectly.
Obviously there is to say that others should do the same test and see if this app will appear among the first applications to battery consumption.
A greeting

disable Facebook app (use web version) and turn off wifi when not being used. My battery usage has transformed! See other thread....70% after 10 hours. 56% after 13 hrs! Lollipop is buggy. Manage wifi manually and you're battery will be awesome.

^^^^this^^^^ . Me too. Disabled damn Facebook and it a few Google apps and I'm back to normal. The main culprit is the stupid Facebook. To make easy access of it from Web just make a shortcut on your desktop.

I will leave wifi on today regardless of whether or not it is connected and see if things get warm / battery usage ramps up. If it doesn't it might indicate an issue with FB alone or at least prove whether or not wifi is stopping the phone from going into deep sleep after a period of non use. Yesterday having left FB and wifi off, resulted in 40% battery remaining after 16 hrs usage. It never got hot once. This is my yard stick.
Lots of users are having issues with the latest update to facebook - just look at the comments on the play store!
Anyone else been having high battery usage but are not users of FB app on lollipop?

@gasland Here is what i did.
I uninstalled
Facebook, Facebook pages, Facebook messenger and com.facebok."something"....
I removed everything that had the name "facebook" and rebooted my device.
Battery has been okay since then.
Ps: I also froze "unified demon" as I don't use either of the weather services or finances or all that crap.

[Q}Lollipop Yotaphone 2 battery life - any fixes?

Hi all,
Having just bought a Yotaphone 2, latest model 801 processor and with Lollipop installed, I was impressed with it... lovely screen, sharp response, great display on the back ....until I realised that battery life on the EPD or indeed doing nothing was (and is) terrible.
This somewhat negates the point of having the EPD. Because whether you use the EPD or not, as others have found, the processor seems to be spending 100% of the time doing something like trying to connect to Google headquarters to report my unethical swearwords as I look at the battery level heading south.
To try and make sure the phone was using the least power, I went through all the running apps and services and terminated as many as I could, turned off things like Yotafit tracking, turned off the service that sends all your contact details to the Kremlin, and so on... then, I turned on the Yotaenergy mode and despite that, we are at less than 24 hours with virtually no phone usage at all. Fully 50% of all the energy according to the battery stats is being used by Android System and Android OS processes when the system is in standby. And the historic battery screenshot shows that the processor is active 100% of the time., even though the phone has not been touched. (sorry, not attached, I'll post at some point, but its not very interesting)
So, does anyone have any clues about how this can be fixed? I have seen screenshots where people have shown that their processors are not active the whole time, and I imagine they have Lollipop? I have heard Lollipop has got some kind of bug which means that data connections are live the whole time, not sure if this is related.
(This might explain the sudden appearance of half price devices on eBay around six months after launch in the UK.)
Many thanks in advance!

YotaDevices has acknowledged the problems on Lollipop battery life, which is the reason they won't be shipping devices coming to USA preinstalled with Lollipop, but with KitKat. Now that I've played around with the EPD and created some widgets/applications for it, I can spot many places where things can go wrong in maintaining battery life and still keep things working.
Personally I've been lucky with the battery life on all versions of Android. When I updated to the last version of Lollipop (firmware 1.44), the phone did show poor battery life for hours after the installation was finished, before calming down to the promised 5 days stand by. Are you on the very last firmware? (Settings - about phone - build number)
As a last resort if your device won't settle down, I guess you could roll back to Kitkat, which had a very good battery life for pretty much everyone. You can install it with Yota's flasher tool: ftp://fw.ydevices.com/YotaPhone2/YotaPhoneFlasher/yotaphone2_flasher.exe
Just carefully select your own region and then the last version of KitKat (4.4.3) they offer. As you are rolling back from one major version to another, I would suggest flashing pretty much everything. You will lose your data.
Yota has said that they are working on bringing Lollipop 5.1 or 5.2 to Yotaphone 2. Let's hope that that works better.

Thanks that was very useful. The question is, will Yota do another build ... or build another device? I'm hoping the Y2 has a bit of life left in it yet and they do launch in the US - it can only help the development community!
I reset back to factory/Lollipop last night as it was eating battery so fast I could not believe it, and I am on the latest build 1.44EU (and was before). Since then.. it doesn't seem to be misbehaving so much, but it does seem to insist that the WIFI is on (when it is switched 'off' in the settings) by 'on' I mean the battery usage recorder... I wil take your advice and 'take it slow' for now, but may flash back to Kitkat if necessary. It is a bit tedious having to reinstall all your apps by hand but this seems to be the only way to ensure it is relatively clean.
The screengrabs below show the phone doing nothing at all in Yotaenergy mode - per first post.

I am quite confident that they will release updated Lollipop sooner or later. They don't have the resources to piss off all their customers just yet.
Your Wifi still does some scans on its own for Google's location service, even if it's not enabled. You can disable this feature in the advanced wifi settings. But that is not the cause of your battery problem. Basically your device is awake all the time, meaning something is holding a wake lock. And by something I mean one of Yota's EPD compoments, which are counted as part of "Android OS" and "Android System" - your biggest battery hogs. It could be one of the EPD widgets that is misbehaving, or it could be some specific combination of them, or just something out of your control.
You could try removing ALL the widgets from the rear screen from Yotahub, then restart the device, and then let it run for an hour with the screen off. Then check the detailed battery log if the device went to sleep or if it was awake. If it went to sleep, you can try adding widgets back one at a time, and then check again if the device sleeps. Basically all the widgets which update periodically hold a wake lock momentarily (time, battery, calendar, weather etc). Of course if the problem lies on Yota's EPD framework, then this wont help at all.

Agreed, I suspect the YotaFit app going bonkers despite my efforts to kill it.... or the Yotagram service, the thing is, looking at the Yota specific apps, you don't really need them, as you can flip the screen with the Yotamirror, and then use any Android app. Sure it would be nice to have notifications on the EPD, but my main focus for this phone is use in bright daylight, and long battery life, not to actually look at the thing 24x7 so I can respond to emails every 30 seconds.
At this point though I'm just trying to determine how bad the underlying hardware is. The GPS on this phone seems to a bit flaky, as does the basic reception of mobile signal. (And I'm not using a metal bumper.) So, I'm happy to flash back to KitKat 4.4.3 to try and give it the best chance..
So, any clues/links about the Yota flash tool? I've put the phone into USB debug mode, installed the flash tool on my windows 7 desktop, and installed ADB/Fastboot as well, but at this point I'm having a bit of an android driver problem, and ADB can't see the phone so that probably explains why the Flashtool says 'waiting for device' when I fire it up. I will go digging to fix that, but I assume that the Flashtool will do all the stuff like putting the phone into bootloader mode, unlock etc...

The widgets I'm running at the moment without any problems are Time, Mini Calendar, weather, battery, and communications (the small widget which shows phone calls, notifications and sms). And of course my own widget.
The best way to make sure there are no useless services running is to root the device and uninstall them completely, but that's another story.
For the flashtool to detect the device, you need to boot it into download mode manually. The easiest way is to turn off your device and plug the usb in while holding volume down -button. The screen will show "download" or something in very small white text. After that the flashtool should find the device. You probably don't have to flash the user partition (it asks for it separately), i.e. the simulated sdcard section which holds all your photos, documents and music.
Edit. And when you have kitkat installed, the first thing you might want to do is to disable automatic system updates. Otherwise it will nag you about the Lollipop update all the time.

I've been facing similar issues and am considering a downgrade when I have the time. I'm really disappointed in yota and won't be buying their next device.
I have found this thread useful, you may too.

thanks gents, oddly, the advice to let the phone 'calm down' seems to be working. I decided not to revert to KitKat (yet), as every day I use the phone the battery life seems to improve. Yesterday it was down to 40%, today 60% after about a days use. I'm thinking a week of running in will give it time to stabilize. I would love to root the phone but I want to use the Good app, and that doesn't run on rooted phones... (shame but I guess that's the flipside of working for a big corporate for you!)

Try putting the battery widget on your epd. If it shows 5 days remaining when you are above 85% and you don't use the phone, then the device works as advertised.
That Good app sounds like a real killjoy. There seems to exist some Xposed modules to disable the root check, but they seemed to be rather finicky to setup and very easy to mess up.

I was suffering from terrible battery life after the lollipop upgrade and the EPD battery widget was never showing much above 1d anymore. After much research and tinkering, it has now improved and I am seeing greater than 3d again. I think the culprits were maybe google fit tracking which I have now turned off and I also de-installed and re-installed the google play services updates which is a tip I saw in an android forum. I also over the last two days have received several yota widget updates which may have also helped. At least for now I am seeing a comfortable day's use again!

I experienced poor battery life out of blue again. I went through all the settings, cleared dalvik-cache and cache partition, tried disabling everything, but nothing helped. It only showed <1 day battery life at 100%.
But then I went to mess around in the developer settings, and when I set the animation scales from 1x to 0.25x and enabled "Force GPU rendering", the battery life returned instantly to 5 days.
Just thought I'd add this to the list of things to test out if someone's experiencing poor battery life. The forced GPU rendering might have some unexpected effects on some software rendering based games.

dont know if this will help but just seen some of the new features of android m "marshmallow" one of which is doze and there is a separate app available on play store for this. i have installed and it has helped battery life !!!

I was going through terrible battery life after Lollipop as well. Suffered, tinkered, tried various things. Eventually I just said screw it, backed everything up and factory reset it from recovery. Since then it seems like it's almost back to it's old self. Obviously having root and using some kernel control apps, greenify and some other things helps it but It will happily do at least a couple of days with little-normal usage. Still don't think it's as good as KitKat but it's not too far off. The EPD really does help spread battery out too.

I did the same thing but a 3 weeks on, the battery is as shocking as ever.
Today, on battery since 0730, now @ 1115 51% and 3hrs left!??
No obvious apps causing battery drain, just google services!

I have had the phone nearly a week, and these are similar figures I experience. What's the point of the epd if my battery dies by lunch!

I think it is something with Android 5.0 that is causing the drain issues. I can go anywhere from half a day to a week with good batteyr life and then it will randomly start draining again. Some background activity seems to hold a permanent wakelock and will not let go of it. I am unable to pinpoint what app is creating the wakelock with better battery stats or wakelock detector since there isn't access to kernel wakelocks in either of the apps for our phone. A restart always fixes things though, so I have a tasker script now that lets me know when idle battery drain exceeds a threshold for too long so I know to do a restart, it's not elegant, but my battery life is exponentially better and gives me enough battery life to make it through the day without a recharge and leave the eink screen on all night as a tv remote.

I got a new phone

In the end, I got a new phone after my Yotaphone decided to brick itself. Its a Zopo Speed 7, Octacore, dual SIM, nice screen, and does 4G very well in my part of the world. It is also around $200 at time of writing. Its a Chinese phone typical of the genre, Zopo seem to be moderately responsive to bugs compared with Yota... This Zopa phone is running 5.1 Android and I can tell you that Lollipop is not the problem...
That's after charging the phone and leaving it overnight, with the battery saver mode on... not too shabby. Of course it won't actually last 28 days, but this phone is nothing special and it is capable of running without all those services running that the Yota has.
The Yota spent its entire time when I had it trying to contact Moscow with that dodgy 'dictionary app'. What (honestly) is the point of the e-ink display if it doesn't save power...

If you are experiencing "always awake" and wifi always on despite your settings saying otherwise it may be worth going into your advanced wifi settings and changing "wifi frequency band" from "auto" to "2.4 GHz only. I remember reading this tip somewhere else for an Android 5.0 phone that was having battery issues similar to this. I made this change about 24 hours ago and have noticed a dramatic difference in battery drain when the screen is off. When I look at my battery stats I am no longer seeing a solid bar for both wifi and awake. Worth trying.
For what it's worth, I have had fairly light use today, some checking of emails and facebook, 40 mins or so of music via bluetooth (with screen off). Total screen on time of 35 mins. The phone has been off charge since 06:30 this morning. It is now 17:00 and is showing battery of 71% with an estimated 2d and 8h left. Better battery stats show deep sleep of 71% whereas previously it had shown awake at 100%. Far better than I had before.

Have you tried using the setting so Wifi is only on while screen is on? (Unless on charge...)

I think I found the issue, at least with my phone.
I was syncing with exchange, and there is a nasty bug with android 5.0 and exchange sync. The sync is taking forever and doesn´t sync everything. Calendar and contacts missing.
Then I removed the ActiveSync connection on my phone and set up the app Nine to sync instead.
After that I got much better battery. This may help for others as well. The phone is just hammering the exchange server all the time and this takes up a lot of power.
