Z4 tablet battery

[setka101]

Hi,

My new xperia z4 battery life seems decreased quiet significantly and the screen usage is 85% is this normal? have a look at attached picture. That's only from non heavy use really. Watched a few YouTube videos. You got any tips. I also got xperia z2 tablet but it's at Sony for repairing the on button, but there the battery seemed better. Many thanks

Well, as the screen is quite big on these devices it uses a lot of power, specially when you have a high brightness. One of the best ways to save battery is to decrease brightness when you're not outdoors or in very bright environments.

@setka101

how long was the screen on?

Well only for about 90 minutes. I also decreased the brightness now Ashwell and tweaked the settings. It was really good when I bought it but after a few charges it seemed to consume the battery much faster. It's now 67%,  so 8% in 30 minutes. I think something is not right here.

There's probably more apps draining the battery 

settings > power management > battery > take screenshots of the list and also the graph and post them here

There you go. It's a bit strange as acouple of them appeared which weren't there before like Skype and Android System.

Let's wait for a moderator to approve the pictures.

OK thanks. I decreased brightness to about 20% will have a look how it goes.

If the tablet is new,the battery life should improve after several charges. And on a smartphone,the screen is one of the biggest battery eaters.

As I posted elsewhere, a new Android device (or one that has just had a system update) seems to go through a spell of rapid battery depletion for a number of days. Initially I had difficulty getting my Z4 tablet to reach 100% charge,  but after a week it settled down
