Battery drain from android os

[Already_taken]

I have a condition with my X compact which causes the battery to drain quickly when the phone is not being used (during the night). This happens every now and then. The battery screen looks like this :

The culprit does not seem to be any particular app. I first witnessed this after the intelligent charging mode kicked in for the first time. I never had these smart charging messages again since.

Anyone else has had this ?

try to boot to safe mode, and observed overnight,,, update us after what happens

Can people please stop suggesting to use the safe mode for everything? That test for the battery is useless. All third party apps get disabled,  sure there will be a lower battery drain. This at the cost that in safe mode the phone is good just for the basic tasks. I'm quite sure not even Whatsapp would be running.. And in any case Sony is now looking into the battery issue. A couple of days ago I have got a PM asking to produce a bug report and to send it back to them.

Hello

I lose a lot of battery on standby e.g. last night it went from 100% to 71%. I turned off wifi(only during the night), gps, nfc and bluetooth. The most energy consuming are google-play-services. I have now 67% left and it says that it will last for 18 hours and 12 min.

Yeah, Google Play Services usually has a quite high CPU/battery usage in my phone as well. I tried resetting its data, with no benefits. But Sony should be working on that, hopefully it will be fixed soon in Nougat (Android 7.0). We may be next getting the upgrade!

I first uninstalled many applications (and disabled most of those shipping with the phone). No luck.

I have tried to limit the permissions of google play services, it complained but let me do that.

I also stoped location services altogether and enabled stamina mode, and things are a bit better

now. I think the play services really look like the bloatware of our time.

Google Play Services (inspite of the misleading name) is an extension of the Android OS. Among other things it contains the service for push notifications. By restricting its rights too much you might end up not getting notifications any mor from your favorite messaging app (as an example).

Google Play Services is on top of my battery usage list (31%) but not because of CPU usage but because of keeping the radio interface active for a quite long time (a couple of hours). I personally don't believe the latter one is a true number, my X Compact runs for three days without recharging easily though, which it definity wouldn't if the radio was active for the time indicated. I made exactly the same observations on my previous Z3 Compact.

By looking at the sreenshot in your first post it is the OS itself using most battery, something that is really strange. By looking at the curve it seems to me something happened around 18:00h on the second day, presumably something that subsequently keeps the processor from enterning sleep mode. Try to remember what you did with your phone at that time, installed a new app probably? Or changed some relevant settings in an app?

I guess you tried restarting the phone already...

[Michelasso]

3 days? Really? Then something must be really wrong on my phone. I forgot to charge it one night and it was nearly out of battery. With about 1h screen time. But it's also true that my network provider is quite bad in my area, if that matters. Still I see plenty of wakelocks (43% of time in 3h, today. And I barely used the phone).

Boff.. Nothing I can do but waiting for a fix (hopefully).

Without root there is no tool to troubleshoot issues like this.

Many android users face similar issues.

Personally I: backup, factory-reset, restore, every 2nd month or more (train often and you get good at it).

The other option is: move to iOS. Or, buy a new phone twice a year:)

My X Compact was draining battery quickly for no apparent reason. Then, I found the culprit. In Android 6.0.1 Settings > Wireless & networks > More > Mobile networks > Preferred network type there are 4 choices. The default "LTE (preferred)/WCDMA/GSM" setting was draining the battery quickly because the LTE signal is weak in my area. When I switched to WCDMA only, I had good data speed and good battery life. You may want to experiment with those 4 choices to see which works best for you.
