Z5 Premium battery draining while sleeping

Hi,

I've been loging battery performance for a while, and I've noticed that there seems to be little variance between drain while in use and drain while sleeping.

Last night my battery dropped over 50% from 100% without any [major] on screen time. The phone was totally disconnected from any radio interfaces, and everything should have been sleeping.

I do have a white list to alow my smartwatch 3 to work while the phone's asleep, but these are things like Google services.

The battery stats for the period when the battery dropped shows;

Android system 10%,
Android OS 7%
Cell Standby 3%
Screen 3%
Phone Idle 2%
Media server 1%.

I don't really code that much anymore, but if this where a system I was debugging I'd be suspicious that Android Systems and Android OS are using such a big chunk of power while the system should be asleep and waiting to be activated by the only remaining interface, the cellar connection!

 

Any thoughts on this [Official or otherwise?]

Barry

Re: Z5 Premium battery draining while sleeping

Hi,

 

Sorry if these are too big! I'm on my PC at the moment, and have uploaded them through Chrome from the Z5P that's tethered to the USB..

I've never had a phone loose so much power while I've been asleep [and it should have been asleep] with all the radio interfaces off! Like I said there is a white list to keep my watch running, which includes [Android Wear, Avast Anti theftl, Google App, Google Play Services, Google Service Framerwork]. Not sure if some of those would automatically be keept awake anyway, it was done largely through trial and error.

Android isn't a platform I've done that much coding on, but I do understand it's basic architecture. Surely the OS shouldn't be consuming that much power. It should be waiting on a listener to be triggered by an event?

The Cell Standby surely should be the only real service that's active. Google framework has nothing to do as the watch was disconected [from the Wear App], which means that Google isn't recieving or sending an messages as there's interface to send them through?

@chris2outwright

 

You are aware that this is a user based forum right? you should contact Sony directly >>> Local support not through social media. 

 

Test both devices on safe mode and also download speed test and report back, keep in mind that the Z5 Premium has a 4K display

No problem, but you might be interested that it only happens when an interface is enabled. Last night I charged the phone to around 97% and put it on airplane mode. These are the battery stats..Screenshot_2016-02-04-07-20-12.png

Re: Z5 Premium battery draining while sleeping

Additionally, just as a general battery performance thing, I've just got up [ with 87% battery] at 7:14am, it's now 8:14am and my battery is at 74%! Is 10% In one hour normal, because that would.pyt my battery life expectancy at around 10 hours with all battery saving options on!Screenshot_2016-02-04-08-15-38.png

Re: Z5 Premium battery draining while sleeping

And with less than an hour of browsing @ 8:54am, my battery's down to 63%! Is this normal?
