Excessive battery drain even in deep sleep. - Xperia Z2 Q&A, Help & Troubleshooting

Basically a huge battery drain when screen off. I tried every trick to mitigate this problem, but nothing works.
Changed the rom, the kernel and tried to disable wakelocks, tried hibernation also, changing sleeping state from hybrid to lcd panel in kernel settings. I suspect a defective battery that needs a replacement but what is holding me back is that when screen is on I get at least 7.5 hours of screen-on time. So basically the battery backup is very good regarding that I do heavy multi-tasking. Please any help would be appreciated much.

Can you try with Stock rom with and without airplane mode and see what the situation is.

Tried recalibrating your battery?

I made a battery test using 'AccuBattery' after reverting to stock Marshmallow rom .291 and stock kernel .291 without any app installed. I turned on airplane mode.
AccuBattery indicated that the device was in deep sleep 99% of the time, however, discharge rate was 3.9% per hour with screen off.
So the question is..
Is it a defective battery or something is going wrong with kernel sleepers?
And just to mention, I replaced the screen around 4 months ago and this problem started to show up gradually since then. Sometimes the screen won't turn off on its own and a restart will solve this problem. Could the screen drain power while it's off ?

Disable WiFi and Bluetooth scanning in Settings > Location > 3-dots menu.

So it seems like hardware issue

[Q] Deep sleep

I left my Note overnight to test the battery drain and lost 40%. I used CPU spy to see what was happening and the phone never really went into Deep Sleep. Android OS was the biggest battery drain.
What's the best way/app to see what is keeping my phone from going into deep sleep? I am not rooted.
Please try a search you will get lots of good answers.

I don't need to be told to do a search. That's the first thing I do before I post a thread. The subject of that particular thread didn't seem to apply.
factory reset should take care of andriod os eating battery more then screen.dont install any app for few hours.only install cpu spy.
Thanks for the suggestion, but I'd rather not have to do a factory reset every time a rogue app is draining my battery. Reinstalling everything all over again is a pain (not rooted, so Titanium backup is not an option) and that's like telling a user to reinstall Windows every time they see a little performance degredation.
I'm pretty sure there has to be a better way. I'll try betterbatterystats and see if it can help me narrow down the problem.
yeh i have an unrelated problem, will resetting device fixes it, but definately not a viable solution
but on topic in better battery stats look under 'partial wake locks',and see what programs are listed first (and the time spent on the apps)
that should normally tell you whats making the phone not got to sleep
u not gone find anything with battery stats.one of ur app is causing this issue.
u can give battery stats a try.when u.have a virus in windows, dont have have to do full recovery instead buying a virus program and trying to fix it.
greyhulk please try that solution Jpeg42 linked to.
Thursday I was down to 30% when I left work(10 hours). Friday I turned on the screen before unplugging and I was at 25% with 2 hours of screen on time and 21 hours since I unplugged.
Unplugging the phone with the screen off seems to prevent deep sleep. Give it a try.
If all else fails, it might be the battery itself. Hardware issue.

Your post is virtually incoherent, however, I will say you seem to be saying BetterBatteryStats won't help, and it most certainly will. What there is no need for is a factory reset, that's like nuking a planet to kill a flea.

Yeah, reading the thread over, that's exactly what I did last night: Took it off the charger with the screen off. I skipped over that thread originally because the title lead me to believe that it had to do with battery drain while plugged in.
I'll give it another test tonight and see if that makes a difference.
I just wanted to post my experiences with deep sleep.
I was getting some pretty bad drain, and I couldn't figure out why. Thanks to the search engine and running into this thread, I tried what you all tried here.
I am running Launcher Pro, and I wasn't going to deep sleep at all. Did the trick posted, even rebooted without it plugged in and it still wasn't sleeping at all.
I cleared the defaults and went back to the default launcher. It went to deep sleep just fine. I cleared the defaults again, then set the launcher back to launcher pro. It is now deep sleeping with the launcher pro as the default.
I then put the phone on the charger, woke it up, unlocked it and unplugged it. Its still deep sleeping. Really weird how it acted, and I figured for everyone else's sake in case they run into that issue again, it could be your launcher that is causing the issue.
A reboot with the phone, after the launcher switch, as the launcher pro as the default, resulted in no deep sleep. Launching the stock launcher while LauncherPro is still the default launcher resulted in no deep sleep.
After a reboot, with no default launcher, launching the stock launcher resulted in, it does not deep sleep.
After a reboot with no default launcher, launching LauncherPro, no deep sleep.
Some really goofy stuff going on...
I am using the overclock kernel but I am not overclocking. I installed it to lower the cpu to 192mhz instead of 384mhz.
I noticed that my phone (Lenovo P700i) barely goes into deep sleep. At the minimum, it always runs at 250 mhz.
Is this considered a deep sleep problem even though BetterBatteryStats shows that there don't seem to be any significant wakelocks?
there's two build props that will make your device enter sleep instanly...If you understand how to edit them..you may want to search for deep sleep build prop tweaks..hope this helps..

[Q] Screen is consuming 53% of my battery!

As the title say, the screen is consuming 53% of my battery, i've tried every single thing and it didn't work.
Here some info about my device:
ROM ICS Pure 7.1 by Spike
Siyah v3.0b7 Kernal
Active widgets: Beautiful weather for weather/clock no animation activated tho
And couple of other widgets (Playstore - Tapatalk - Calender ) Others are just normal icons/shortcuts
Battery calibrated after ROM installation
Today my battery went down from 100% to 50% in just 7 hours of soft use, couple of calls/SMS and games for around 15 min and that's it!
Auto brightness, Wifi OFF, 3G/Data packet OFF
Also i'm using Juice Defender ultimate.
Here is some screenshots.
What's the display on time?
I've tried to use Jd it's a waste of time buddy.i had paid version to. here are some tips which i successfully use: 1 use dark (black) backgrounds for everything including your home screen- this I'd the biggest Batt saver on amoled screens anyway. 2 don't have notifications/active widgets on (they use processor etc)
3 if you really want Batt life increase think about an extended Batt -i have a 3500mah in my gs2. 4 don't use juice defender or any app killers .these things run in background and use processor and Batt. I've been using these procedures and they do work. hope this helps.
Sent from my GT-I9100 using xda premium
ps the screen using most showing most Batt usage is a good sign - it means everything else is consuming less Batt. but your post is a little worrying concerning wat you said 50% Batt. rogue apps are a problem that run in background. or the other major Batt killer is Android OS killing Batt in singer phones. try to look out for these 2 things.
Sent from my GT-I9100 using xda premium
The screenshots do not show under which circumstances the power went down. The battery screen shows only the last 52 minutes and does not include the screen on/WLAN/GPS/awake times. So it does not show which share the screen had in the power consumption during those 7 hours. If you had the screen on most of the time and used your phone - even for light things - 50% seems not too bad. If it was off most of the time, it probably took less than 53% power.
And in Better Battery Stats, you can select between "since unplugged" (that's what you have, showing only 8 useless minutes), "since charged" (that's what you want to check) and "since custom reference" (also very interesting, if you want to check the power usage during a certain time). Also check the kernel wakelocks.
turn down brightnis
Thanks for the replies, here is some more screen shots about Partial/Kernal wakeups
I noticed some wakeups in the kernal, i just changed my background to a black one also done some tweaks, ill report back tomorrow, meanwhile if those screens indicate for a problem, please share the solution
PS: Also i'll try CF-Root LP7 instead of siyah
In battery post your display time
Wakelocks are probably not your problem. The device was awake not much longer than the screen was on.
Also, did you notice that the power went up even after disconnecting from the charger? And before, there is sudden decrease, probably you restarted the phone at that time. You might want to try to reset the fuel-gauge chip with ExTweaks.

That what i thought too, not wake locks, because sometimes battery behave good but it drops fast after it wake up, also i've been monitoring the wake locks and everything seems fine, i've reseted my "Fuel-Gauge" My battery dropped to 12%, What is this chip suppose to do? Thanks

[Q] Wakelock issue on stock

I didn't have this problem for quite some time now, but now it appeared again. I am on stock sense with Android 4. Neither s-off nor root. It seems as if the media scanner server ran for some minutes and drained the battery heavily. As you can see on the second screenshot, the screen was turned off while the device remained active. Has anyone experienced this yet, and what is the reason? On top of that I had to retype my PIN. So the gprs connection must have been disconnected while the display was turned off.
That large drop looks like a reboot. I do have times occasionally when the phone is active with screen off, so nothing seems out of the ordinary there.
A reboot could have occured, which I would regard as critical already since I didn't do it myself and my phone was subsequently disconnected from cellular network for quite some time after. But still: What happened afterwards seems to be even worse: I think it must have been the 17 minutes of MediaScannerService being active that caused the massive drain.
It's a reboot, there's no way in hell you dropped 30+% in a split second

I noticed rebooting again sets you back to normal, but that's just me
I would guess the battery readout is wrong if you have it in deep sleep for a longer period of time. But for me the problem isn't the wrong reading but the cause for the high drain and the reboot. And I think it is a wakelock issue.

[Q] Battery Draining No Matter What I Shut Off... Why?

Hello,
I wanted to get your guys opinion as I believe my phone may have turned defective and I really don't want to go down the Warranty Route as I'll loose the phone for weeks. And willing to try anything suggested.
So here's the problem:
Battery Draining at very high rates. On stock battery, I am draining about 12% an hour, after 6 or so hours my 15% battery capacity left warning turns on. I figured it was the battery, so bought a double capacity 4200mAh Hyperion Battery. Now my battery drain is at 6% an hour (which is equivalent to the factory battery considering the double capacity).
I am currently on XXELKC 4.1.2 Stock ROM. When I first noticed the problem, I was on 4.1.1. Figured I would ODIN, Wipe all cache's, and start clean. This has made no affect on battery life.
Here's what I've tried:
- 4.1.1, 4.1.2 Stock ROMs from Wipe - High Drain
- Airplane Mode with Location Services Disabled - High Drain, but 4.5% an Hour instead of 6% an Hour.
- Disabled all Samsung Apps - seemed to have little impact
- Disabling Google Now has made zero impact on battery life.
- 4.1.1 BBS revealed nothing - may need to try again on 4.1.2
Any ideas? Or is this sounding like the phone? Is it possible after a wipe the phone, when I re-enter my Google Credentials it is restoring some data which is defunct and causing high drain?
Note: Screen shots are with the double capacity battery taken right after a clean Odin upgrade to 4.1.2. Only ran Android Activation and thats it.
It looks like your phone isnt going to sleep properly. Try a custom rom/kernel.
Have you done a full whipe ?? If not, do so, and don't forget to make a back up first. It worked for me !
Sent from my GT-I9300 using xda premium
I had similar issues, I factory reset worked, and I also download rescan media root app to disable the media scanner which was my main battery killer.
WHen you do the factory reset make sure your phone is connected to the internet, so it will prompt google to store the apps you have and remote install when you sign back into the phone.
I have performed a full wipe but that had minor impact on battery life but I wounder if the Google Restore possibly restored an invalid setting. I will try this again without entering my credentials and see if there is a link with a restored setting. I will have to give the rescan media app a try as well.

Any specific kernel in mind. From what I've been reading no kernel seemed to stand up to magically solve battery issues without voltage drop or cutting services like Google now from the rom.
use better battery stats app to determine what is causing those wake locks.

I have attached a run with BBS for 1 hour. Nothing is really standing out. The phone was in deep sleep for all but 2 minutes. I did have Google Now and Location Services Disabled as that was eating away an impressive 10 minutes / hour from deep sleep. But my battery life only increased from 6% an hour to 4.5% an hour. An improvement but weak IMO considering the larger battery.
Results from BBS is attached.
I once had that kinda issue too
What I did was Factory Reset and that did the trick for me
How about trying the app CPU sleeper?

I've had this issue before on the i9100 Galaxy S II, where it didn't seem to matter what I did, it chewed battery just as soon as I put my Google account back onto the handset. I believed it was caused by the Samsung calendar bug. So absolutely; try it without putting your Google account onto the device.
Also, your WiFi signal looks low, although this has less of a difference compared to having low mobile coverage...

your first post has a huge amount of wakeocks that arent going to be reflected with an hours run on BBS. If i were you id charge it to 100%, unplug just before going to bed and then show us the BBS log in the morning so people can see whats happening over an 7-8 hour peroid

Its more what apps are using the wifi connection and waking the phone up, thats what the op needs to look into

More information can't hurt. Post in and Maybee there is a correlation.
OK. So I went ahead with your suggestions and did the following
Factory Wipe again from Settings Menu
Went back to factory Samsung battery for consistency in reports to other users
Took out both my sim and sdcard to eliminate those possibilities
Put into airplane mode
Disabled a bunch of apps (ss on next post)
Still bismal results but better than before. 7 percent an hour drain. Attached all the files. Ideas? Google says phone is awake but bbs doesn't seem to shed any clues for me...
And here are the disabled and installed apps
your phone isnt going to sleep at all....something is keeping it awake..try a stock rom ( any will do) with full wipe. Dont restore anything with titanium backup. Disable auto sync on everything. Set wifi sleep policy to always. See if the problem persists.

That last run posted was stock 4.1.2 XXELKC firmware and Factory Wipe from Settings Menu. I also performed Wipe and Cache Wipe in the Bootloader (Power Up + Center + Power). All I did was install bbs and never put in Google or Samsung credentials and disabled some stock apps from running.
If your not referring to factory Wipe, can you please explain further? Thanks.

[Q] How to max the battery life ?

Well i just got the LG G3 and am using it on GSM.
prior to using i rooted ,TWRP and loaded jasmine 4.0 , also put in skydragon kernel 2.9.4 s 3.0 had crazy boot times.
I am trying to get the max out of the phone what ive noticed is that the phone just doesn't wanna deep sleep.
I have greenify , xposed (amplify) and noticed the issue of battery being drained when idle , i went to sleep and saw it was at 50% , woke up to 10% battery, my older phones never dropped more than 2% overnight,
To investigate loaded BBS and wakelock detector , nothing that pops up out of the ordinary
So my question is what do you guys do to max the battery outta this , what can i do ? i dont really see any apps causing it to wakeup . suggestions or any would be appreciated
any other stock rom also if you could suggest for battery life ? ive heard good about cloudy 1.2 as well.
I have really gotten great battery life out of sky dragon along with the 3.0.2 SD kernel (kernel is in the orig Dev section). Along with amplify ad greenify.

Are you connected to WiFi when your phone won't deep sleep?
I work from home, so my phone spends 90% of its time on WiFi - I was getting terrible battery drain and only 50% deep sleep on a good day. One day, I left the house and noticed great battery life and plenty of deep sleep on a 4G connection (which is the opposite of what I expected).
After trying nearly everything, I discovered the fix was as a simple as turning on the "Battery Saving for WiFi" setting under Settings -> Wi-Fi -> Advanced Wi-Fi". I've been getting great battery life and deep sleep times when I'm at home now.
Give it a shot and see if it solves your issue.
Also, ever since daylight savings time went into effect, I noticed both my phone and my wife's phone keep randomly changing time zone for no reason. Looks like the phone is struggling to automatically detect the time zone from the carrier and causing battery drain as a result. I disabled the setting to automatically detect the time zone (and manually set it for PDT) and the battery drain stopped on both of our devices. Could be unique to my area but may be something to try as well.

I thought the same as well which is why I discounted this as being a cause for 4 months....I have 15 other android devices and none have exhibited this behavior so I was surprised that such a trivial setting could have had this impact.
To answer your question, I am currently running:
- BeanTowns stock 11B ROM
- SkyDragon 2.9.7 kernel
- Xposed installed with Disabled Services running
- Selected stock apps/services disabled
I don't use greenify/amplify (don't see the need as my average daily drop is anywhere from 1.6% - 2.4%/hour with moderate use).
