Given that I have updated to IOS 9.2 my Ipad 2 Air is discharge the battery in 12 to 14 hours, even without any use. Before the update, after a day of average use of the battery was still 70-75%. How can I reinstall the IO 9.1?

Hello

The best way to save battery life is to go into the settings and turn off Apps Refresh

I now get 3 / 4 hours of battery life more.

You cannot return to a previous ios 9.1

See you soon

Brian

PS

If you still have a problem iCloud backup now

Then restore settings to get rid of any bugs.
