Re: Z5 Premium battery draining while sleeping

None of this actually matters anyway. I've accepted that this phone basically doesn't have anything even close to a two day battery life, and and if no one cares when it suddenly dumps over half the battery for no apparent reason I'm not going to bang my head again that brick wall!

Re: Z5 Premium battery draining while sleeping

you know very well that it's not a solution. The ability to seemlessly use a £100 smartwach made by the same company [without it shutting down bcause the phone drop's the connection] of the £500 phone it's paird with isn't to simply alow it to not communicate with that phone so that the handset can get more battery life by shutting down the radio interfaces. I said that I wasn't going to bang my head against a wall, but don't go telling people that an unexplained battery drain has anything to do with the whitelist. I have the exat same setup, and it's not done that for some time. clearly it was an aborent event....

Re: Z5 Premium battery draining while sleeping

To me it looks a bit like the battery usuage stats you see doesn't really add up.

In the latest screenshots you posted the screen has been using 16% of the battery according to the stats. However, it has been on for 3h and 36 minutes. I think the display should account for more of the battery usuage in this case.

There's also something keeping the phone from sleep. This is probably why you see that battery usuage on the OS.

 

Would you be willing to send me a log from your phone? I will forward that internally to see if we can find what's keeping it from sleep and why it uses that much battery.

To do this:

Settings > About phone > Build number, tap 7 times on the build number

Go back and select Developer options and turn on "USB debugging"

 

Charge phone full

Restart your phone

Use it as you normally do until battery starts to get low and then:

Settings > Developer options, select "Take bug report". When the report is ready (might take a minute) you'll get a notification that you can tap and share it Google Drive. Please send me a link to it in a private message.

Re: Z5 Premium battery draining while sleeping

I had the same problem after marshmallow update after a day the battery was down to 18% after trying stamina mode it made no difference and lost charge overnight with the phone shut down. Here comes the good news, my phone sim card stopped working and I had no network I use tesco mobile so I went to my local store and got a new sim and after waiting 24 hours for activation everything works like never before, it's day 2 since my last charge just under 48 hours and my battery still has 53% left. So I can only say try getting a new sim it worked for me like never before at this rate I should get 4 day's life

@Gmh

How did you try Stamina in Marshmallow?

Re: Z5 Premium battery draining while sleeping

Barry, 
I'm sorry I don't have any anwers, just experiencing the same problem as yourself. 
My batter seems to drain more at night, while I'm sleeping and obviously not using the phone, than it does during the day when it's being used.  One of the reasons I bought this phone was because of its reputed battery life, unfortunately, like yourself, I'm having to charge my phone more frequently than my old one (a Samsung, which was my other option, it was the size of the phone which was the deciding factor int he end). 

If anyone is able to help I'd appreciate it.  As mentioned I see very similar patterns to yourself.

Many thanks

Re: Z5 Premium battery draining while sleeping

You've hit the nail on the head there. 

One day at best, with minimal use. 

 

Raise an an issue and it's always either blamed on wifi being on too much or apps keeping it from sleeping. 

 

Then, just when hen I had made peace with the single partial day of use being the norm...

 

Last night I went to sleep with the battery at 40%, yet it was flat before my alarm could wake me for work 6hrs later. 

$400 out of pocket today thanks to my Xperia. 

 

40% to 0 percent in less than 6 hours without a single use or activation of the screen. 

 

Useless.

Re: Z5 Premium battery draining while sleeping

Did anyone find a solution to this? I'm seeing equally poor battery use. 

 

I see about 10% drain per hour when it's not being used. I unplugged it today at about 7am and then had to charge it up again by 4pm despite not using it. 

 

I love Android, and I've been on Android for eons, but I have to say that my experience of the terrible battery life on my Z5 since 6.01 has left me looking at an iPhone as my next device. I just want to know the phone will be on when I pick it up.

 

Is there a forum mod out there who would look at some debug logs for me from my phone perhaps?

 

Olly

Re: Z5 Premium battery draining while sleeping

Something to try for those having these problems: remove the SD card if you have any. I'm pretty sure my current SD card is broken, but one of the effects it has is that with the card inserted, the battery lasts about 8 hours of normal use. If I take the card out, it's around 50 hours. All of this without ever explicitly using any app that accesses the card.

Re: Z5 Premium battery draining while sleeping

I would give it a go but I think that Google Play Music won't reload the offline downloaded music you remove the card and run the phone without it. DRM n stuff.

 

I can't live without my offline music Slightly frowning Face
