Re: Z5 Premium battery draining while sleeping

Sorry, I didn't see this message [I've had one cup of coffee]. Given that I was directed here by things actually on my handset I assumed it was. How do I get in touch with Sony? I do know it's a 4k display, but I don't think it's the reason the battery is so bad. There's no way anyone would release a high end handset with performance that's this bad. Also it doesn't explain why the phone still drains when the screen is off and the handset's only connected to the celular network. It should go into standby, not carry on using up battery. IMHO something's going wrong somewhere in the Android sub system!

Re: Z5 Premium battery draining while sleeping

Here's something very interesting, and I should add that it's only early days! However0 if I restrict background process to 4 in developer options the battery remains steady. It stops the off screen battery drain. Normally there's a constant drain on the battery, even wen the phone's not being used. Now it's only using battery when I'm actually using the phone [it's held its charge at 51% since my.last post until I started actually using the handset to post this [it's now just dropped to 48%] which is somewhat heavy on battery for one post, but it's a lot better than it was. It's not however a real solution! It's obviously just preventing the service that's causing the drain from executing in the background...

Re: Z5 Premium battery draining while sleeping

I don't own Z5 premium, but regular Z5 and use it for 2-3 months now.

last 6-7 days it started to act just like you describe it, loosing 30% or more over night.

Any suggestion is welcome!

Thanks for the screenshots but you forgot one, the graph, tap on the graph and take a screenshot.

Re: Z5 Premium battery draining while sleeping

I think my battery draining problem is solved.

Sony updated Album App jesterday, and I updated it this morning.

After that I restarted my phone, and no more battery drain.

 

Will see what happens till tomorow, and I will confirm it here.

 

Cheers

Re: Z5 Premium battery draining while sleeping

Hi, 

 

I've done what you asked and charged the phone to 100% then used it as normal, running it down to 10%. I've taken screen shots from the battery usage screen, including all details from each service or app that appears on the screen. 

 

 

I've attached the images to this message.

 

 

God luck and thanks for the assist, if you can help I will be delighted [still can't find any official Sony support as all support leads back to this forum..
