iPad iPad Air battery life on iOS 7.1 abysmal

How did you install the update? OTA? If so, I would try a full restore to iOS 7.1 via iTunes and see if that fixes it.

 

When you install the update it may have enabled Bluetooth. Disable this and see how it runs.

 

Ah thanks for this! My battery was draining much quicker too and I see now Bluetooth was indeed on.

 

I was referring to backing up your phone to iTunes and then do a restore of the phone to iOS 7.1 and then load your backup. That's how a lot of people end up updating their phones when they experience issues from a OTA update.

 

My bad, sorry. I still would recommend doing a full restore to iOS 7.1 after you back up. Try that and hopefully that will fix your battery drain issue.

 

It seems battery life improved with 7.1 on all my i devices - iPhone 5s, my Air, and 3 rMinis wife's and kids'.

This is from my Air. Just OTA 7.1 update.

 

Same with mine. WiFi, Bluetooth and LTE data on. When I got down to 8% I had 4 days 7 hours standby and 1 day 11 hours usage. This is much better than 7.0 was for me.
