Hello guys, I am new here but I know I can get the best answers here. So what is my problem? I have an Xperia Z2 which had a problem with the display and it was replaced some months ago. I needed to change the rom and unroot the phone so I can send it for warranty. A was using lollipop 5.0.2. Before sending it for repairing upgraded to 6.0.1 sent it and after I got it back I was not happy with 6.0.1 so I decided to go back to lollipop. Installed many 5.0.2 and 5.1.1 roms(using now 5.1.1 .232 rom) but it makes no difference there is a battery drain that I never had before(before I was at kit kat 4.4.4 upgraded to 5.0.2 and rooted it with kingroot). Now I flashed original 5.0.2 ftf file using flash tool and after that prerooted 5.1.1. rom. Ok what is the problem. Android OS is draining the battery mostly. I tried to install betterbatterystats but it didn't help me to solve the problem I think it was showing suspend_backoff as the main wakelock. The problem mainly occurs when I'm traveling. I don't know why but If I leave the phone at home there is no wakeup, but If it's in my pocket and I`m traveling somewhere it starts to get hot when I check it my battery had dropped a lot and the phone is awake. In power management Android OS is the process that keeps the phone awake. I have disabled all the things that I have never used now and before(before the screen replacement) - GPS, sync, wifi and mobile off, stamina on. I don't know where to search. I don't know what can be the problem. I don't use the phone a lot, tbh I hardly ever use it, I was able to achieve 23 days with a single charge before that but now with these drains it can hardly pass a week. I don't know where to search? Even when it's not keeping the phone awake(or at least the stats are saying so) I lose too much battery(7-8%) per day if I don't use the phone, it was 3-4% before I sent it for replacement. And I had also never seen Android OS or Android System in the battery stats before now I see both. And here comes the 2nd question. Is it normal Android System to keep the phone awake during calls? I noticed that if I activate the speaker Android System is NOT keeping the phone awake, but if I talk as normal without the speaker active Android System keeps the phone awake for the same time that the call takes. I am sure it wasn't like that before because I hardly ever used speaker and never seen Android System shown in the battery stats. I am wondering if this can have something with the fact that when they returned me the phone with screen replaced there is a problem during calls I don't know if it's with the proximity sensor or lighting sensor or something else, but when during a call even tough the screen is off(so the proximity sensor seems to work), I am pressing buttons on the screen with my cheek while talking, that's the reason I am using the power button to manually turn the screen off and this problem does not exist but it's a fact it wasnt like that before the screen change.
I will be glad to hear any ideas and if more info or screenshots of something are required just ask.
For your first question, I AM REALLY IMPRESSED that you said there were a 23 days usage in one single charge, I have NEVER had that much battery life even back in the days when using symbian devices. And 7-8% drop PER DAY is really less than normal and you should thanks God for this. Okay, back onto topic, this "battery drain" should be caused by Google Play Services. Roll back to a previous version of the app so your battery life may come back. And for your second question, the Android OS MUST BE AWAKE in order to run the phone process, it is impossible for you to say it wont run if you turn on speaker.
23 days with minimal(no) usage man but in normal mode with stamina on and perfect 3G signal, not ultra stamina. I was just doing something like a test. There is no way to use it like normal and have that much out of your battery. Actually only calls and not every day. But 10-15 days wasn't a big problem with my usage which is like 10-15 minutes per day on screen and same time for calls. Now this way it can hardly pass a week because of these wakeups.. And 7-8% per day I mean if you DON'T use the phone(deep sleep with stamina on), even in the specs of the phone it's written that it should last 28 days in stand by, but with 7-8% lose per day in STAND BY no way to happen, but it was possible before(when I made the 23 days test). Let's say just rarely checking the clock. Thanks for the advice of google play services I found the same on the internet and already did it. Uninstalled the updates of google play services but the problem is still there now with the stock version I see lower number of processes running under google play services(when I check running apps there are 5 processes, with the latest version there were like 8-9 processes). There is a location service running btw should this one be running when I have turned the GPS off? The problem mainly occurs while traveling so I'm starting to wonder if it's not something connected with the GPS, but it's off according to power management battery stats.
As for the other thing I don't know Android OS(that's only keeping the phone awake when I'm traveling with the phone in the pocket, first part), but I meant Android System is awake during calls. And yeah I can clearly make the difference even in battery drain and also in numbers. While talking on speaker Android System is NOT keeping the phone awake and this way draining less battery(~4% per hour), but if I talk like normal Android System is keeping the phone awake for the same time the call takes and this way the battery drains almost twice faster(7-8% per hour) compared to using the speaker. Haven't checked for the Android OS, if it's keeping the phone awake during call or not, but the Android System does when NOT using speaker.

I just decided to upgrade to the new firmware 6.1.A.2.45 and then realized that the amount of RAM usage stays really high 520 mb all the time. Before the update, it would usually hover around 400. I decided to leave the phone uncharged over the night and the phone had drained down to 10% over the night (7 hours), whereas before it would drain about 30% over the night. I checked the battery usage and noticed a ridiculously high amount on the android system and OS and was wondering if anyone knew what sorts of things the phone might be doing and how I would get around them?
Thanks.
This is a well known problem. Main solution at the moment is to always leave Wifi enabled, even when not connected to any Wifi networks. This will help the phone sleep and will prevent android system from awaking it up as often.
It can also take a day or two for the battery to settle back to normal after a flash.
thanks!
i was considering restoring to default settings because i've noticed some of my apps lagging a whole ton, such as music player taking forever to turn on. is there anything that can fix this?
Because Im seriously curious... This phone has a rap of being "atrocious" in terms of battery life... Now I'm not making this post to be mean or anything, In fact I really do want to know what IS causing it or some theories.. and share one theory I have
But my personal experience really says otherwise, Tonight I set a new "record" on my One X+, 16 hours 28 minutes with 2 hours 43 minutes screen on time... And I didnt do anything "extreme" to achieve it, My Google Now is on, my location services are on, autosync is enabled.. About the only thing I have done is install JuiceDefender (My previous record without Juice Defender was about 15-something hours) I watched youtube videos, Read some websites, listened to music, and even played some games... I'm completely stock, no roms or anything
Now, I will note, I had a problem the other day where my battery killed itself, FAST.. After a bit of digging around and tweaking, I discovered the cause was that my One X+ wasnt entering Deep Sleep, and thus the processor was staying at 475mhz or so even when the screen was locked (Causing the battery to be drained like i was using it) What caused this? My Wi-Fi, of all things, While I had a really good signal, I had it prioritizing the 5.8ghz radio, and in my room, the 5.8ghz signal is fairly weak as im a ways from my router... so the phone was switching between it and the 2.4ghz signal, causing the phone to be unable to sleep, Removing the 5.8ghz AP from my phone fixed the issue completely and my phone returned to "normal" behavior...
Yeah i know it sounds really farfetched and weird, and took me a bit of googling to get the idea that this might be what was causing my issue (I tested my hypothesis by turning Wi-Fi off completely and using Cell data, Sure enough my phone slept like a baby and barely used any battery.. i flipped Wi-Fi on and suddenly the phone was drinking its battery down rapidly.. I disabled the 5.8ghz AP and suddenly the phone worked 100% properly again)
I suspect that this is the cause behind some folks who are saying their phone is draining down 7% in 20 minutes with it locked, Its simply not entering deep sleep, the processor is doing something in the background... Could some of them be having the problem i just described? Its possible, Especially if you have multiple Wi-Fi points in your house.. Could the wi-fi in the One X+ be bugged? I dunno, Thats possible to, Thats why I'm posting this...
Now of course some people need a phone that is going to go for 2-3 days without a charge, and no, this isnt the phone for you (There arent many smartphones out there that can manage that if you actually USE it any) But really.. 16 hours with 3 hours of screen on time is pretty darn good.. Thats getting quite close to my Galaxy Nexus with a 3500mah Extended Battery (Around 18h standby, 3.5-4 hours screen on) despite all of the "handicaps" the One X+ has over the simple GNex (Like LTE and a Quad Core processor) and is vastly better than my stock Galaxy Nexus battery which died constantly...
And yes, heres a screenshot as proof if you dont believe me...
I just want to add that I find that googlenow also drains the battery and as such I always disable it. It was a problem on my S2 and thus I have disabled it on my HOX+
Honestly, mine wasn't lasting longer than 8 hours until I rooted it and simply "froze" all of the AT&T apps I wasn't using. That alone gave me an extra 2-3 hours a day of battery life! (I've read here that the AT&T apps, even if you aren't using them, keep running in the background) The other thing that seems to help is an app called Smart WiFi toggler that's done wonders for both myself and everyone else I know who uses it in terms of minimizing WiFi battery usage.

I'm sure other folks have other tips, but this has been the winning combo for me.
I should add that i also froze every ATT app i could and never opened ANY of them.. So maybe thats part of it as well..
JuiceDefender i believe is doing something similar for me with the Wi-Fi by turning it off when its not needed...
My battery life was terrible when I first got this phone. I let it charge out completely once this month and I've been using LBE Security Master. Those two things have greatly extended my battery so much I have been able to go more than a day with it before charging. Another factor might be that my phone isn't carrier branded or anything.
The "My Wi-Fi isnt letting my phone enter deep sleep" thing is actually starting to get annoying, I thought i fixed it but it keeps coming back...and yes, it is legitimately killing my battery at twice the normal rate because the phone will -not- enter deep sleep
My phone goes into deep sleep just fine if i turn Wi-Fi off...and my battery drain returns to normal....So it cant be some app downloading stuff or constantly pinging the internet or else it would do the same thing when im on LTE...
Also i've reset the "Keep Wi-Fi on during sleep" option to never 20 times now, it keeps going back to "always" on me...
Ideas?
My battery life is ok. See here:
http://forum.xda-developers.com/showthread.php?t=2067143
Mine is too, Provided i turn Wi-Fi off or i get the bug to go away for a bit (basically toggling wi-fi on and off a few times and twiddling with the settings makes it work right, but the problem comes back minutes or hours later)
Otherwise, Wi-Fi wont let my phone enter deep sleep, and my battery drains like im using it..
The thing thats annoying me more is that the "Keep Wi-Fi on during sleep" setting will not stay where i set it and keeps going back to the default setting....
I guess i can just toggle wi-fi on and off manually...
Hi
I searched the web and also on Xda but I could not find an answer to the problem I got. I want to know if anybody has the same problem as I have. Firstly I want to clarify that I am NOT talking about a normal battery drainage caused by background apps, foreground apps, enabled wifi, bluetooth, google background activities, synchronisation, facebook, google location settings, any antivirus app or something of that kind. There are plenty of threads about that and google search is full of this topic. I am talking about something else when it comes to sudden and quick battery drainage.
It already happened to me a couple of times when I use the built in projector of my phone (samsung galaxy beam). So I watch a movie on the projector and it takes let say.. around 30 percent of my battery life. After I turn the projector off, close all foreground and background activities I wait like a minute or 2 and the battery status drops from lets say 28 to 20. This is normal as the battery status somehow needs some time to get "updated". So after every single fore- and background activity is closed and I got 20% battery left I go to bed. Then in the morning I look at my phone and its dead meaning the battery dropped to 0 causing the phone to turn off. And thats not normal for me. (I do hear the sound of very low battery in the early morning meaning it doesnt turn off within 1 hour which would mean faulty battery) First I was thinking that this problem might be caused by previously overheating the battery but I checked the temperature and here all is fine. Also both batteries are not too old and still work normally (beside the described problem). I may add that using the projector itself is not an "extreme" usage of the battery. When I use the projector, play an HD android game connected to my ps3 controller ...that is a different story.
So my question is what could cause this rapid battery percentage drop even tho the phone has no activity at all and sleeps. Sometimes it happens and sometimes it does not tho..If I would not use the projector then I loose around 2-3 percent overnight, if I use it then I sometimes loose 20% without doing anything. And thats not normal. I understand that a lot of people dont have my phone, but I still would like to know if anybody had the same issue on his phone after "heavy" usage? Maybe android somehow thinks that there is still activity even tho there isn´t. Like a virtual activity making the battery think its in use and therefore draining it. Any thoughts on that?
Im running on 4.1.2 JB stock rooted
Which phone?

I wrote that already in the post. Its the Samsung Galaxy Beam.
ya, even my xperia m with JB 4.3 drains heavily.
This is a case where actual current measurements will narrow things down.
It could be that when you turn off the projector, there is still some hardware drain going on.
It could also be that the last "20%" of your battery is really only 1%.
For current measurement, see: http://forum.xda-developers.com/showthread.php?t=2487055
this can be due to some defect with ur battery or with the charger that you are using, you can rule this out may be by trying different charger and also changing the battery to rule out the battery defect. what @Renate NST say could also be the issue.
Problem solved
Ok. Just a little heads up. I managed to solve the problem. Thanks for the replies. This is how I solved it:
1. I first ran this app ( Battery Life Repair) to check for any faults in the battery itself https://play.google.com/store/apps/details?id=com.BoshBashStudios.batterydoctorrepair
2. Then I installed this app (BatteryCalibration): https://play.google.com/store/apps/details?id=com.nema.batterycalibration and followed the advise as written on the app (regarding full charge and discharge- I discharged it until the phone switched off). Find the XDA thread of this app here: http://forum.xda-developers.com/showthread.php?t=1024867
3. After I watched a movie on the phones projector I restarted the phone and it stopped from draining the battery until 0 and went back to a normal discharging state
So with a bit of heavier battery usage (watching a movie on the projector) the phone or battery somehow memorized this usage, and thought it has to continue in this state even after I ended the movie and turned the projector off. But the above 3 actions solved my problem. Its important to mention that you will still loose some battery life as you need to restart the phone. But this is obviously way better than having the battery run down to 0% for a virtual usage... :good:
PS: If you still got problems with ur battery you might want to replace it or change your charger...
Hey guys! I want some advice to check if this problem is normal or maybe its a manufacturer defect.
Anyway, I bought this phone about 5 days ago, and in the time I've been using it, my battery lasts about 7 or 6 hours (also it takes like 5 hours to fully charge it, which makes it worse). I thought it was because the stock ROM isn't very optimized, but later I started using cm 12.1 and it seems to last almost the same. Also, I started using an app called "current widget" that checks continuosly some info like the mA that is using at the moment, and I found that when I use it, it's mA is between 500 and 600, and sometimes it's like 180. Is this normal?
I'm worried because I've read in reviews that the battery of this phone lasts about a day and half and mine barely lasts 7 hours. Please, help...
Mine will last for 2-3 days if left alone. I'd download an app or CPU monitor to see what's running and draining the battery.
I repaired it already ^^ I just flashed official firmware again and no more battery draining and heating.
Battery draining could be many things but usually comes down to rogue processes.
Since android is java based over C, it becomes a garbage collector. Be sure to clean your device frequently to avoid internal confusion.
If a simple cleanup doesn't work, you can try to remove processes from loading at boot.
I honestly think that a reflash of your ROM is a bit extreme for a battery draining problem. I would try to exhaust every other avenue first.
I know, but I even tried disabling apps and it stayed like that. Also I flashed other roms and the problem didn't stop. I was going to claim my warranty and that's why I flashed everything again and somehow that solved it. I suppose my carrier modified the software somehow and that's why my phone had that problem.
Put your phone in airplane mode when you aren't using it. See if the battery drain persists. How is your signal? If your phone has a low signal, it will actually boost its radiation to try and keep the signal or establish a stronger one. This only is a battery killer and an issue that cannot be fixed by any software/firmware update that I've ever heard of.
If what I suggest seems to be true, airplane mode will be your friend. Or at least turn off data while not using it.
Good luck!
Hi guys, I don't know what's going on, but my phone's battery has just turned to crap recently. Today, I left for work at 7 with a fully charged battery, and hardly used it aside from a few texts. By noon it was dead in my pocket out of nowhere (my battery saver mode never came on any of the times I did check a text). After that, I threw in my second battery at 12:30. After browsing on my phone to 87% on my lunch break, I started checking on my battery from there:
Within a half hour, my battery life went down 7% to 80%.
Another half hour passed, and it was down to 77%
After another half hour, 74%
By 4:12 PM, my phone was at 68%
54% at 4:45 after reading and replying to one email
Looking in GSAM, I see that 57% of my battery is used by apps, with Android System taking up 18%. OS Services is also my highest data use today, at 16.9 MB. Screen wake is only 1%, so it isn't a wakelock issue. I have sync, bluetooth, wifi, and NFC turned completely off, and am on LTE throughout my work day, with a good connection.
Strangely, even though my phone is in my pocket for most of the day and GSAM says Android System is #1, the built-in battery usage setting shows Screen as #1, followed by Android System, then Android OS.
I'm honestly at a loss right now. I can't think of anything new that I've downloaded. My phone usually makes it through an 8 hour shift fine and then some; the thing has pretty darn good screen off life normally. Please help me figure this out!
I think, because it happens to me at work, that is something related to marshmallow amd wifi, Try to go in the advanced wifi settings and select only when connected under the second option in the menu, Then See if it is better.
Another person that works with me has the problem with his s7 edge so i thougth that it could be related to the wifi bug of marshmallow

try to see if disabling location is doing anything
I always disable it because google services is calling it a lot of times (I know that it's for "lost my phone" feature and so, but still disabling it anyway)
Yeah, battery is bad. I have to G5 for a week. Its a great device but tge battery sucks.

Try turning off Always on Display. That batters battery life.
I get a full day, minimum 4 hours SOT at 75-100% battery.
Fingerprint also wastes battery.
