I've never actually owned an iPad, but this weekend I've burrowed an iPad Air from work. Now, I've always been under the impression that it was rated for about 10 hours of web surfing. As of right now, I'm at 6 hours of usage (mostly all web surfing on chrome), plus 1 day and 17 hours of standby, with 71% battery remaining! I'm on pace to get like 20 hours of screen on time. If anything, companies usually overstate battery life, but this seems far batter than any estimate I've heard. Is this really typical iPad Air battery life?
