Xperia z5 Premium battery Drain so fast

[sajkhan]

I was having a similar issue however stamina mode has helped a lot...also it has the superfast charger that helps...think I'm gonna keep this phone....I'm sure with future updates Sony will iron these problems out..

I have checked my screen time...1hr34mins..I've gone from.100% to 58%..no gaming just Web browsing...with my brightness around a third..personally feel this pretty poor...my note 4 use to last much longer...I mean this phone only uses it 4k when watching 4k content...so on a 1080p screen what's using up the battery??..I don't even any apps installed that drain my battery....I also have the stamina mode on...have another 10 days left...thinking about returning the handset and going back to Samsung...

That's definitely not okay.
Either there is something wrong with the software on your phone or it's a faulty battery.

Try repairing the firmware with the PC Companion and try battery life without installing stuff. If this doesn't help exchange the phone.

Hi...is it just Web browsing or have you been doing other things?? Games? You tube?

Mostly Web, some music via headphones, 1 or 2 YouTube short video, a few pics and 2 or 3 uhd videos to show my mate.

I've fully charged my battery with stamina mode...estimated battery time says I have approx 13hrs left??? 10 days stand by??? Doesn't seem right on estimated battery

I haven't even used my phone yet

Based on average,
If you just have fully charged it and then immediately checked this, it will calculate a lifespan based on the fact that you've had the screen on 95% of the current usage etc.
