Hello.
I've been searching various forums for a fortnight now to try and diagnose an SII issue I've been having and Google inevitably brings me here. Unfortunately, the numerous threads on battery drain don't match the problem I've had and the solutions haven't helped.
Around two weeks ago I noticed the battery life on my handset was really terrible, draining in hours. I had been using it quite a bit at the time so assumed this was the cause. However, lately it has been draining within around 6-10 hours even when idle, usually dying completely overnight despite a full charge just before then. I don't have a huge number of apps installed - maybe 20, fairly standard ones like Twitter, Facebook, Amazon, no games and no 'battery defender' style apps. It's not rooted (it's 4.0.3) and I can't root it for other reasons.
The battery drain was a nightmare, basically going from power point to power point just to keep it topped up enough to use and it was draining during idle time and deep sleep. I very rarely ever have 3G, GPS or Bluetooth switched on. Wireless is on most of the time and it generally does have a signal in the two places I spend most time (home and work). It also has a strong Vodafone signal since I'm living in a major city centre.
I tried a few things:
1. Uninstalled all but the most-used apps I had. No change.
2. Uninstalled everything it was possible to uninstall. No change.
3. Installed BetterBatteryStats and CPU Spy. BBS plus many hours of searching kernel/partial wakelocks and so on showed nothing that looked odd at all, certainly nothing taking up a lot of time or regularly stirring the phone. CPU Spy showed it did deep sleep when idle.
4. Factory reset. This included no app installations except BBS, disabling the likes of Social Hub, Gaming Hub and all other stock apps I could. No tethering or wifi sharing, no wifi, no 3G, no GPS, no Bluetooth, nothing running. It was basically a handset sitting there doing nothing. BBS showed nothing odd that I could see but the battery still drains in hours. No partial wakelocks and a tiny number of kernel wakelocks taking up next to no time and occurring a handful of times. No change.
5. I charged it before bed, took the battery out and left it until morning. In the morning it was down at 79%. This seemed weird so I bought a brand new genuine Samsung battery and gave that a try. No change in the 6-10 hour drain but taking the battery out overnight showed no drain now.
6. The weirdest of all. I charged it fully before bed, switched it off over night and it was drained completely by morning. That seems crazy to me. I can fully understand poor software or bugs draining a battery but not when a handset is switched off.
I am lucky enough to be able to get a new handset through work but this issue really annoys me. I took very good care of the phone, never installed anything crazy, didn't over charge it, the handset never got warm at any time, I'm careful with Wifi/GPS/Bluetooth/3G and location services, yet I ended up with an effectively useless "mobile" phone.
Is there anything that comes to mind that could have caused this? Point 5 above made me think it was simply a battery issue and maybe it partly was (with two batteries, how unlucky) but point 6 is just crazy. What could cause a handset to drain a battery under these circumstances?
Thanks for any advice!
Take the phone to Samsung Service Centre. No phone should drain that quick when un-rooted and a full wipe has been done
Sounds like tha battery is shot.

Um...widgets? Some widgets on stock Samsung ROMs kills your battery - I remember AP mobile news is a huge drainer. Try limiting the number of widgets you put on your homescreens maybe?
Hi...
Try:
01 - Full Wipe
02 - Install a clean ROM
03 - Disable Fast Dormancy ( *#9900*# )
04 - I use the GreenBatterySaver
After post your result !
I sugges too full reflash the stock rom and after count the batter time. If it does not help, it cold be HW error too - maybe it isn't.
Hey guys and please dont crucify me. I know there's a ton of other battery issue threads on this forum and on many others but I cant find the right one. I have looked up each and every one of them, about mediaserver draining the battery about the android system and so on. I have done everything each thread said to, downloaded greenify and hibernated most active apps, disabled and froze certain bloatware with titanium backup pro and so many other things. And I think that the battery would be supposed to perform at its best right now. I am not a very heavy user, I just use my phone for music, calls, a little gaming and the occasional facebook/messenger/browser session with either 4G or WiFi. I have everything everyone ever said turned off. Things like auto backup of Google+ and all location services and auto sync. Screen is constantly at 65% brightness. To further prove my point, at this point in this post which took me like 3 minutes to write, my battery has lost 3 percent. I can leave the phone unplugged all night at 100% and when I wake up it will be at 95% but the moment I pick it up and start playing some music or some games the battery goes down really fast. I can even compare it to the battery of my old Xperia S after a year and a half use which was like 7 hours altogether. Battery stats say that mediaserver takes up 20ish% battery and Android system goes over 40%. I really don't know what to do. Do you have any suggestions?
Thanks in advance, George.
you should look at the time it depletes when screen on, if its below 5 hours from 100% downward then its not good. I have noticed the battery still charges past 100%. So leave it an hour after it reaches 100%. I would also recommend using the charger that came with phone. No usb charging for these tests. Dont use phone while charging either.
Also freezing\debloating can be adverse, at least thats my experience on battery life. So I recommend going back to stock full clean with factory resets.
No recovering of apps or app data for these tests. No contamination so to speak.
Also lg roms allow you to switch off services via taskmanager settings, in settings app you can disable what you dont want to use. No need for debloating\freezing etc.
Switch off location settings, gps and bluetooth for this test. Search for carrier iq on lg g2 forum and how to disable it via settings. Switch of cloud storage(dropbox/box etc) and lg backup stuff. Only google accounts, wifi and mobile networks.
Now for the screen on time test, just use browsing apps. No games or music\movies.
Your screen on time should be 6 hours approximately. From 100 to 0. It can be 5-6 hours. If its below 5 then its not good. this is with good network coverage btw.
thats what I would do

Have you tried better battery stats, wake lock detector, or even gsam battery monitor. Maybe you have Google location services on?

Yes I have tried all of the above. Only thing that sticks out is something called 1013 which keeps running and waking my phone but I think it's something about the sound. Next is Android System with many wakelocks and as I said with 30+ % battery consumption. Everything location-wise is off. Actually everything is off. Every setting. Things go to hell when I open 4G or WiFi. Also I have the international model so I don't think there's carrier IQ in my device, or maybe I didn't find it in an app suggested by someone here for that purpose. System Tweaks I think it was.
Could you post a screen shot?

I've had android 4x do this on multiple devices, multiple roms for no apparent reason. Wipe it and start over. Wipe everything. Especially directories with any form of music, sound files, videos... ( Use LG Flash Tool and go back to stock 4.2 for example will do just that )
So the OTA came over to my country and now it seems like BBS and WLD are broken. Can't really do anything to show you the more complex battery stats and can't really say that the battery has improved. Reducing the brightness did have some effect but I am not really fond of having it at such low values. Anything else I can do to minimize the Android System battery consumption? Its bigger than what the screen is using, even when it was at 70% brightness.
Sad to say my first LG G2 just got replaced today & am now running into this problem with the 2nd phone. Its literally night and day battery life performance between both phones.
First phone had 0 issues and by now I'd still have battery % in the 90s. New phone is sitting @ 63% after 3 hours of use (setting up phone, few reboots here there....just factory resetted for the 2nd time to try and clear this etc)
Culprits are:
Google Services
Android Core Apps
Media Server
System UI
Both phones are: 4.2.2
build: JDQ39B
Software: D80110c
brightness (which never was an issue)= 45%
O.P,
has your situation improved or worsened since you've encountered this problem? I'm thinking about sending my replacement back for another replacement

I can now say that the battery life of my phone has improved. But sadlyf the problem was probably some corrupt mp3 files that I moved directly from my old device which forced the mediaserver service to run constantly and thus the android system. :/ I still can say that I think it drains a bit fast when I use it for browsing, Facebook, games and stuff but at least when I check the battery consumption, the only things stated there that make a difference are the screen at ~30-35% and the game which I was playing or for example Chrome. It finally feels like that whatever I use drains the battery and not something else in the background but I don't have that good of an impression for the 3000mAh "beast" battery of the G2. Awesome phone though.

I ended up returning my replacement phone and am back on my original G2 until I can get a proper replacement. I can tell you, the G2 does have an awesome battery life if you get a good phone out the box.
The differences between my first G2 and the 2nd one tmobile sent me are night and day. Get a replacement phone while you still have time.
Should have my new one next week. Just hope it's exactly like my first one.
Ex....been using it all day..I mean heavy usage...and in still @ 75%..and the phone is cool to the touch
The replacement g2 would [email protected] 36-37% by now and running hot

You're on 4.2.2, not 4.4.2 when you have the 1013, is that correct?
Try rebooting when the volume is on, rather than rebooting in quiet/vibrate mode.

The OTA came to my country some days ago. Still the battery feels kind of small. Is it normal to lose 1% every ~1-2 minutes on 4G browsing? With nothing else on. No gps no G+ backup no anything.
Hi Everyone
I’ve bought yesterday a brand new Samsung Galaxy S4 here in Brazil (model GT-I9515L, it’s a Snapdragon 600 4G one), and I’m kinda worried about my battery life, which drags 1% every one or two minutes on simple Wi-Fi web browsing, I have been from 100% to zero in less than two hours, and I honestly don’t think that is normal.
I’ve tried a lot of things, I tried disabling some battery dragging features like the gestures, gps and etc, and still got terrible battery life
I’ve noticed that if I sit the phone down idle (screen off but powered on), it doesn’t seem to drag the battery much, when idle it seems equal to my Nexus 4 that I had previously, I'm starting to miss this phone more and more since I got the Galaxy.
The charging time is normal too, it goes from 0 to full in average time, two hours or so.
My phone is in 4.4.2 Kitkat (TouchWiz, unrooted) I’ve haven’t done anything to the phone other than apply OTA updates once it turned on the first time.
I’ve tried doing a factory reset via the settings menu (is this the same thing than reseting from recovery?) and not installing anything after but still got the battery drain problem.
Thinking that it was a faulty battery or phone I’ve brought it back to the store (an official Samsung Store here in Brazil), but they told me that my software was out-of-date, which I thought was strange because both the Software Update menu in phone settings and Kies found no updates to be applied.
I watched them as they put my phone in Odin mode and plugged my phone into one of the store’s computers, opened a program called “samsung master” in order to update my phone, but they couldn’t do it because my “Knox” was somehow messed up (which isn’t because it shows as 0x0) and told me to come back another day when the technician is there.
I became really frustrated with this, so far what I could diagnose was that somehow that my battery drain problem is a software one, and is solved by some kind of update that isn’t available by Kies, just in Samsung stores.
Can you guys give me any directions? I’m open to suggestions and if you guys need any other information, please tell me that I can post here, sorry for my English because I’m brazilian.
Drain almost always applies to when your screen is off. If you don't have drain while your screen is off, then it's perfectly normal.
2 hours of screen on time is perfectly normal. Your screen uses power, not much you can do about that.

When it's off, the batteery seems to last, but the performance is way worse than on my Nexus 4 (which is known for it's bad battery performance) when it comes to screen time, I've got near the double web browsing time on the nexus.
Your galaxy drains battery like this too? it seems insane to me. 2hours from 100% to zero without any of the features, brightness on the lowest level, only Wi-Fi on, I don't think every galaxy is like this.
When I brought them to the store, the salesperson told me that it had an update to be applied, but when I search for an update or put it into kies it shows me as up-to-date, do you guys know anything about that?
Here you can find the latest

Though I doubt a firmware upgrade would change it.
And yes, 2 to 2 1/2 hours screen on time is what I get.
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 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.
No Bluetooth, No Location - Yes WiFi, LTE 100% signal coverage, no downtime, overall low brightness around 25-40% I can't seem to get past a day of regular use with 2 hours and half average screen time. Using latest OTA.
I've turned off the always-on screen, several bloatware that came preinstalled, including Facebook and Whatsapp.
The first on the battery usage is always Android System followed by Cell Standby then Android OS (again???) and then Screen. Also the voice call seems to use some great amount of battery. Naming might be different since my Android is in another language.
Have turned on energy saving for most apps that runs on background. Doesn't help much since I don't have many apps that runs on background. Imagine if I did! My day ends with about 20~27% battery left, I just turned off fast charging to see if it helps anything. My Xperia Z3 with Whatsapp and a great deal of apps installed would end the day with over 50~65% with Stamina Mode. I know the screen is smaller but so is the battery.
So I thought it would get better with time but it didn't, it's the S7 Edge Exynos Single SIM, unbranded with the official Samsung rom so I could get the latest updates or I would be stuck with no updates at all since Frebuary, since my carrier usually only releases major OTAs such Android N and skips all the minor updates.
Yes I did a factory reset already hoping for the better, maybe I got a defective Galaxy S7? I'd hate to have my phone fixed and the battery changed, it wont be the same again unless they give me a new one which is unlikely.
Why is Android System and Android OS draining so much battery? Are there any tools to debug this and trace which processes are using CPU time? Or could this be due a faulty battery?
Settings, Applications, Google. Disable all the services that will cause wakelocks such as all security options. This is something 99% of folks overlook or forget. Post a screenshot of your battery stats

Only settings marked above are "Allow remote lock and erase"
Here is an average day with:
**Few moments connected to my laptop transferring pictures from yesterday - so incidentally it took some charge on the way.
1 hour 29 minutes voice call, 3G/LTE signal is excelent, VoLTE not used, WiFi on occasionaly, Location off, Bluetooth off.
1 hour 12 minutes running Fallout Shelter with power saving on, 30 fps low resolution mode, that's the CPU time at least.
2hour 28 minutes screen time with very dim brightness
Power saving ON all apps where available, I have absolutely nothing installed but a couple of games, Teamviewer and Microsoft Remote Desktop.
That left me with 49% battery. Not sure how great the results are considering the brightness was very low.
Since the image took the whole page, here are the links instead lol.

Dont quote me on this but I believe the Android System drain issue is a byproduct of the latest Samsung firmware update...
Someone more in the know could correct me or elaborate more

Just some heads up, in offline mode my phone went a full day with a 6% drop, half hour screen time and some minor gaming, when I turned the phone radio back on around 20:00 when it was 10:00AM it was down to 15% battery, solely on standby. No bluetooth No location - Yes Wireless Yes LTE
