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. https://imgur.com/a/61FWK 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.
