Another update: It now turned out that my 10.5 iPad Pro also exhibits battery drain issues. Because the problem is now more general I decided to create a new thread.
These are Canadian prices but they are pretty fair. My first round of AppleCare will probably go to a battery, and the second round will go for a screen and I’ll pay for a battery since it’s already open. After that my kids can fight for it. My money is on the younger son, but the older might surprise me ?How much does the Apple store charge for replacing the iPhone X battery?
DND would't help I guess since I don't get a ton of notifications. Full restore would be the last resort but while the battery issue is quite annoying it's not annoying enough for me personally that I would go through the process of restoring the device ?
I will try it tonight ?It only takes a couple hours. I would highly recommend it in your case. That battery drop is very high.
