The is issue not with the batter or any App. It is with the OS update.
I have two phones and they both have the same issue since the update and my 15yr old
son has the same issue too. So the two phones in position with the same batter
problem all after the upgrade of the OS.

It is either an issue with the OS on the older devices or a setting the the OS turned on or off
and I would hope the Android will help resolve because things were great before the upgrade.

Also, I noticed that my batter windows shows Android System using 31% and Screen 25% and OS 15%
