Xperia Z1 Compact battery problem...

[Komprende]

Hello folks from Sony,

I have my Xperia Z1 Compact for about a half a year now. Today i noticed an amazing thing, coming back from university with 60% power and an hour later 40%. It seems to discharge quicker. The Android version on that is 4.4.4. What is going on?

Settings, power management, battery, check what is draining your battery

Perhaps wifi, as you might be auto uploading photos while on wifi
