I see posts on the web about battery drain (yes my iPhone 7 has that issue) but my bigger issue right now is I’m Having trouble with my iPad Air2 not charging after ios11 update. It was fine before the update I tried several different cables and outlets. Even tried plugging the usb into the Mac. I reset the iPad. I also restored it in iTunes and downloaded iOS 11 and set up as new iPad. Still not charging. Any other ideas ? I searched the web and saw posts about the same issue but that was on the beta. Any ideas?
