Battery usage error

[sm355g]

There has been a 29 minutes of screen on time since charged upto 80%. Haven't used any apps since the last charge, the phone was idle for the whole time of 4 hours and 4 minutes. 

So my question is "screen on time of 29 minutes" ....How?? ..and I was not staring at the home screen lol..

Nothing on lock screen...everything is disabled.

Battery after the april update **bleep**.
