I would like apps to be updated automatically when my phone is plugged in (charging) and on wifi. I can easily allow auto-update only when wifi is on with the appropriate option in the Play Store settings, but not prevent auto-updates from occuring if the phone is running on battery.
This is causing an unecessary battery drain when I am using my phone on wifi at home. Given that auto-updating apps is more a daemon job than a time critical task, I cannot believe it is not a standard power saving strategy.
Do you know any apps or system workaround (including if the device is rooted) to achieve this?
