IOS 11 may have destroyed my Air 2 as a device and battery wise. Please hear me out. So confused.

    I apologize if this is the wrong place to put this but you guys are going to know more on the iPad side of things so I picked this part of the forum. If it’s more suited to the iOS 11 section please tell me.

    I’ve had it since launch. Although 2 years ago I did receive a replacement when the mic broke. Since then absolutely no issues and the battery has worked like when it was new.

    This all changed when I updated to 11 last week. My device started acting buggy and weird and the battery was definitely poor. I then downloaded IOS 11.0.2.

    My fears the next day were completely gone. I got ridiculous battery life. I think I had 24 hours of standby time and like 13 hours of actual use. I was beyond pleased as you can imagine. Then next night this happens. I use my device a few hours before bed and I got up in the morning and it had drained by about 10% I would say. The usage time was off but I wrote it down as another bug. No big deal I think to myself.

    Then last night happens. I used my device for 2-3 hours at most before going to bed. I wake up to find it almost halfway drained. I look at my usage and I’m floored.

    This was all on the absolute lowest brightness with no background refresh btw. I used Firefox to listen to a video in the background but then closed the app before going to bed. I’d say my usage mark then was about 2.5 hours.

    As you can see the usage and standby time is absolutely absurd and doesn’t add up. Not only that but all day today I’ve had my dock disappearing randomly. My iPad going down in charge while it’s plugged in. And then when I turn the device off and on it’ll show completely different charge percentages. It just feels completely out of control and like the update killed or bricked my battery.

    It would have to be an extraordinary coincidence for my battery to have just all the sudden broken as soon as IOS 11 was downloaded.

    The Apple rep wasn’t helpful at all and didn’t seem to understand that the math of the usage being totally wrong was my complaint. It went over their head so I ended the chat.

    I have read all the articles about preserving battery and I’ve turned off anything that I can see causing this. I did a reset settings but not a full restore yet as I don’t have my own computer ATM to do a back up on and I need to save some stuff that can’t be iTunes backed up.

    Does anyone here have any advice or thoughts? I’m really starting to think my Air 2 is on it’s last legs. I’m praying it’s just a bug but this seems pretty extreme.

    Edit: apologies if the post seems over dramatic, my Air 2 means a lot to me, i use it for almost everything I do, I don’t have much money and really don’t want to replace it and this is stressing me out badly. I’m sorry.

    I had a question about that. My latest backup was on 10.3.3. I know restoring from that won’t give me iOS 10 back, but as a backup does that work?

    Or do I need a new backup. Sorry for dumb question. Thanks man.

    Avoid using Firefox for a while. As a guess - Firefox doesn't use it's own rendering engine but the default Webkit one, same as Safari. Perhaps watching this video may have left it running in the background. How did you close the app? Did you force close it by going to the multitasking screen and flicking it off, or just minimized it?

    Back up should be operating for everything except IOS and any 32bit apps which cannot run on the 64bit system.

    I’m not completely sure what I did. But I’ll absolutely be force closing it tonight to try. Thanks for the tip I’ll report back.

    I know I didn’t force close safari. Maybe I should do both?

    What could cause this change though. And should it not still show I was using it for hours?

    Pure speculation, but iOS 11 may have changed how the Webkit renderer works in third-party browsers, and Firefox may have to update to accommodate.

    However, if Safari itself is not cleaning up properly in the background, that's definitely an iOS 11 bug. I haven't encountered many iOS 11 issues, but it certainly needs polishing I think.

    I have used every major iPad release and the Air 2 surely was one with quite poor battery performance from the start. Coupled with the usual extra power consumption of a newly released operation system, it's not going to be a pleasant experience. But I'm quite surprised with Safari consuming more than 70% of battery in the usage stat... what kind of websites you usually go to? How about installing some ad-blockers to reduce javascript usage?

    I mean I go to all sorts of different websites. Mostly forums, reddit and news sites. This device had always fetched me about 10 hours before so I definitely think something weird is up. I like to keep the lights low so it helps my battery.
    How would I go about installing the ad blockers? Any suggestions?

    What iPads have the best battery to you?

    Do a clean restore and monitor your usage. I’m thinking your iOS 11 upgrade didn’t go well.

    Also if you have a backup of iOS 10 variant then you can restore it on to 11 but not the other way around.

    In any case I’d suggest not to restore from backup and use the device for a few days “as new” to compare the performance.

    I agree with the post above. I had 11.0 and 11.0.1 on my Air 2 for a while and although I thought the animations were jerky and laggy I didn't have any battery or general performance issues. Archive your backups and try a DFU restore then set up as new and see what happens.

    On iOS10 some people solved a similar issue by switching off Bluetooth when not in use. I also had a similar issue caused by my VPN. Switching both off has reduced overnight drain from 10% to 1%

    op my Air first gen still runs like a champ, so there is no doubt the air 2 should handle iOS 11 just fine. Like others said maybe try a clean restore ?

    Battery life same as iOS 10 for me.

    It looks like you may be right! I closed out Firefox and safari and there was no “fishy” usage like before.

    The battery is still pretty weak compared to that first day on IOS 11.0.2 and IOS 10 so idk what’s going on.

    I’m going to try to leave safari in the background tonight and see if that shows usage.
    I’ve got a new computer coming so that’ll be my next step probably. Also I really appreciate all the kind help everyone is offering me. You guys are very cool.

    Still having poor battery and very weird bugs. I’ll turn my iPad off and and then on and I’ll get a different percentage than what I had. I think my battery indicator is getting stuck somehow as it’ll appear to not charge sometimes.

    New computer did not arrive so I haven’t had the chance for a fresh start. Just giving an update. Should be in tomorrow

    May be painful, but do a wipe, restore the OS from a freshly downloaded copy off iTunes, then set up as new (do not restore from a backup).

    If any of you want to do this procedure, please read this post:
    https://forums.macrumors.com/threads/battery-issues-since-update.2069726/page-19#post-25205678

    At first I wasn't getting this right. Then I found this link:
    http://www.redmondpie.com/how-to-clean-install-ios-11-via-itunes-the-right-way/

    But I still think there are battery issues anyway. However, as explained before, please set up as new and don't restore from from a backup after you do a clean install for the last iOS 11 version. You'll have to redownload all apps and reconfigure all settings (except for a few ones saved by iCloud, such as Safari bookmarks and your photos).

    Okay wait. So you guys think I should never restore from backup?

    Or just use as a new device as a first step.

    I have thousands of photos and lots of notes that aren’t iCloud so this is a scary thought lol

    You might try what xraydoc suggests and see what happens with just a few apps installed . If the iPad behaves normally, you could try restoring your backup.

    Some use an external wireless hard drive instead of the cloud. For max safety a copy should be kept off-site.

    So on my new computer I can just put all my photos there from my iPad? Is it pretty easy? Never done anything like that before. It just arrived and I’m trying to figure out how to get iTunes backups on it.

    Also my battery is still messed up, today I ran it to 0 as a test and it cut off at 10%. Sigh. It seems that the battery doesn’t ever show drain in standby mode.

    Pretty sure IOS 11.1 will fix battery issue.
