I’ll have to play more with it for the other things. I haven’t invested much time in troubleshooting, since it seemed like that’s the way iPads just are now. Hopefully that’s not actually true.
When I looked at the top battery consumers in the past there wasn’t anything that stood out. I think home screen was at the top. It wasn’t one or two apps killing it with background activity.
Since the biggest battery consumption associated with home screen is the display, and users are only briefly on the home screen, before using it to navigate elsewhere, home screen should be near the bottom (1%) of power consumption.
