    Just noticed this. Seems a lot better than 8.1. Unplugged since around 4:50am today, and on LTE the whole time with 40 minutes of usage (Reddit, Twitter, Facebook, and Safari); still on 100%. Brightness at 50%: http://imgur.com/pQMMod8

    Anyone else?

    The whole system is much more responsive on my iPad Air 2 and iPhone 6 Plus. Performance has been restored to the 8.0.2 level.

    No, after 40 min of playing a game in combination with Tune-In I lost 3%. Is that normal?

    3% battery life for playing a game for 40 minutes i.e. you can play this game for 40 mins x 33.3 = 1333.33 minutes = 22.22 hours of continuously playing the game. Impressive.

    Well I didn't play 40 minutes long, I think like 10-20 minutes and like 20-30 minutes browsing the web.

    Wow that is impressive! On WiFi the whole time and how do you have your brightness configured?

    Either the battery meter is broken, or the battery usage has seen vast improvement. It looks to be much better for me too.

    Only on WiFi, brightness set automatically. However I guess the counter is wrong. I will see the next time I fully charge the iPad.

    Wow. I haven't updated yet, but if you all are seeing improvement, I'll do it as soon as I get home tonight.

    Thanks for the heads up.

    Huh? Is it still not working? I haven't heard that one before.

    This is my iPad 4 battery life. Mostly safari browsing and watching YouTube. Seems almost too good for some reason.

    Battery is still OK on my Air 2 but nothing like my Air. I'm getting 10-12 hours vs. 15-20. I definitely have to thin about charging this device much more than I did the Air.

    I found that right after I upgraded my Air 2, the battery meter was off. It said I'd get over 20 hours and that seemed too good to be true. After I ran it down and recharged it, it went back to normal, but I still got an extra 2 hours of use from it - I was getting 10 with how I use it (browsing, twitter, Hungry Shark) and now I'm getting 12.

    I took this screenshot right before upgrading to 8.1.1 since I'd have to plug it in. This was on 8.1 which I had probably 10 cycles on before.

    There is definitely battery improvements, like 40-60 mins more for me, when browsing, didn't count it when playing any game.

    Air 2 on 8.1.1 Battery Improvement

    Battery life too good??

    It doesn't feel like I have had this much screen on time since my last full charge. Not complaining, just wondering if this is correct.

    iPad Air 2 wifi (brightness on 40% auto)
