With 5.1.1 battery drains in standby as fast as in use

Manivald — Sat, 27 Feb 2016 08:34:09 GMT

Hi guys. I need help.
I bought a Z3 tablet compact a week ago and my battery lasts in stand by as much as it lasts in use.

I tried in safe mode, same result. I have a 4G sim installed and stamina disabled. Droid 5.1.1
It should last orders of magnitude longer in stand by ...

I read somewhere that you should be able to resolve this issue with going into recovery mode and erasing update cache. I cannot get into recovery mode with instructions found online. I read that should get you into recovery:

1. shut down

2. press power and volume down and after vibration release power button

Does not work for me. Results in safe mode boot. I also checked from dev options that the device is not sim locked.

Please, help, ideas?

You can't go into recovery mode on Xperias

We'll need more info to better assist you

charge the phone 100% use it as you normally would then once the battery reaches 10%

settings > power management > battery > take screenshots of:

1. the list
2. tap on the graph and take a screenshot
3. back > tap on the top 4 items on the list > take a screenshot of each

post them all here or upload the screenshots to box or dropbox or google drive or etc and post the link

@Manivald

You have app and/or services that kept your phone awake, it could be anything from autobackup or auto updates to a third party app, you could try again for few hours in >>> safe mode

Roger, here are screenshots with an almost complete cycle in safe mode. I set it to safe after I did some DJI stuff, but it still shows in the list. I suppose that is normal?

So, do you have any Ideas? What should I try? It is really annoying. The battery seems to be in good health, but something keeps it awake in stand by?

EDIT: I removed the SIM card and it appears the gremlin went quiet and in standby the device lasts now. I will charge a bit and try see how it goes without SIM. Although if it helps it ultimately is not a final acceptable solution

@Manivald

Seems to be an app or setting that keeps the phone awake, WiFi its on all the time so that drain the battery but it has to be an app that keeps the phone awake

Do you agree that it has to be some part of the devices software not something I have installed myself, since it also stays awake in safe mode?

Do you have any suggestions, what could I try to resolve the issue?

Should I try to revert to previous firmware? Or would it be wise to sit tight until Marshmallow is here?

@Manivald

This is how to find out

repair the tablet with PCC > do NOT install anything, don't enter your Gmail account, don't restore anything, take some screenshots and report back.

Manivald — Wed, 02 Mar 2016 07:17:22 GMT

You mean I should factory reset and after that do the same process of charging and discharging and screenshots as before?

Uliwooly — Wed, 02 Mar 2016 07:54:41 GMT

@Manivald

not factory reset but repair the phone with PCC

Re: With 5.1.1 battery drains in standby as fast as in use

Manivald — Wed, 02 Mar 2016 17:24:46 GMT

So, I did the repair thing with PCC and did not log into anywhere, but had the SIM card inserted still. I also logged into my local wifi. It apperas the problem persists.

There is some problem with the graph, but the device was powered for two hours just sitting in standby and lost several percent of charge.

App 4: https://dl.dropboxusercontent.com/u/59385246/z3/Screenshot_2016-03-02-17-45-09.png

I guess it is now established that the problem is somewhere in the default software of the device?

What could I do to resolve the issue? Thank you for your assistance!

@Manivald

were you using the tablet at all or was it off?

Re: With 5.1.1 battery drains in standby as fast as in use

Manivald — Wed, 02 Mar 2016 19:18:40 GMT

It was on and mostly in standby. I checked the battery level at times and browsed a few webpages in chrome but did not log any apps into anywhere.

@Manivald

This is quite odd, @Nabeel @Quester @alexdon

do you guys have any suggestions?

Something is keeping the phone awake most of the time.

Since even software repair didn't help, I think it's best if you get your tablet examined at Sony service center Or if you bought it from a Sony center, then you should probably pay a visit there and see what they suggest about it. Your tablet is completely new, they might provide you with a replacement.

It could be a hardware issue i'm afraid.
