Hi, I'm a longtime iPad user, since the first generation. I upgraded to an Air 2 from the iPad 3 back in November last year. I've always felt the idle battery drain has been high, but assumed this was because I restored from the backup of my iPad 3. Recently however I decided to do a full restore. I did nothing except setup an email account (set to poll every hour), I then charged it to 100%, and after that left it for a few days. Weirdly, after 3 days idle it has been active for nearly 8 hours, that's 11% of the time. I've noticed this pattern. Can anyone think what's going on here?
