Battery performance

[Judysung]

Got my x performance two days ago and have been using it in stamina mode. Battery level dropped 15% in 4 hours without browsing the Web, only used for instant messaging... Is this normal? I expected longer battery life with this new phone

I think I know one particular app that caused a huge battery drain. It's the AVG antivirus app. You can't uninstall it, but only disable it. I disabled it....and my battery life improved.

There was a lot of built-in apps that I can't uninstall for some reason.

Safe mode is the best solution i have found, the error is inconsistent, and drains the battery quicker if the phone has been left without a restart / update for a longer time, running noguat the other intermittent touch problem and this battery drain are the only two problems which persist, with my limitted perspective
