Poor Battery Life

[AlexanderH]

Hello everyone!

I've recently acquired an Xperia Z2 (couple of weeks ago) but i'm not very satisfied about the battery.

The longest on screen time I've ever managed was 5,5 hours with stamina mode enabled and screen brightness turned to 50%.

On normal days with normal usage (facebook, browsing, whatsapp), and Stamina disabled I only get around 4-5 hours.

It's not that it's that low to start complaining but after reading so many reviews about that great battery life of the Z2, the fact that my gf's Glaxy S5 lasts double as long as my z2, and the statements of sony that you should be able to watch video on 80% brightness for >10 hours; I started wondering if something was wrong with my battery.

Someone experiencing the same thing?

How many hours on screen do you guys get?

Tech details:

Android 4.4.2

Version 17.1.2.A.0.314

Thanks in advance!

Someone?

If you check the "Battery Usage" section in the Power Management area of settings, what are the top three applications/percentage of battery used?

Here are some screenshots I just took.

You see, 4% battery with only 13 min on screen time, is that normal?

Hi ,everyone ,
I have sim free z2 from german Vodafone, but sw is custom for Vodafone -17.1.2.A.0.323.

Experiencing battery drain on idle, battery slowly disharges at few %/hour .Stamina is on, Extended mode is also on, everything for saving is on, 3G/4G/Wifi is off,screen brightness - Auto  I think there is some nasty bug in these, never sw's. They improved call quality, but at the same time broke something else.

I have been getting pretty poor battery life with the new facebook messenger app. If you have this installed try removing it and restart your phone. My battery life was back to normal after that !

Hope this helps

i find the first 10% seems to drain without much use. im thinking its the latest firmware causing it. going to try to repair the firmware at some point to see if it fixes it.

@AlexanderH - At this stage I am not seeing anything out of the ordinary, can you try taking the screen shot again when it is down to say 10-15%
