Hi all, I've had an iPhone X since release, so a little over 1.5 years. I'd say I've taken great care of the device over that time frame. It's never had a broken screen or been dropped into water or anything like that. A couple of days ago it was at about 70% battery and it just shuts down on me. I wasn't able to turn it back on, hard resets don't work, nothing. I get home and plug it into it's charger and it boots right up. It then stays turned on for about an hour then will shut itself off again. Now it doesn't always boot up when I plug it in. Sometimes I have to try a couple of times. Took it to the Apple store today and they said all of my hardware checks passed. Their recommendation was to restore it completely and if that doesn't work to bring it back for replacement ($550). I haven't had the chance to do the full restore yet (will try tonight if I can get my phone to boot up). However, I was curious if anyone else thinks this is a battery issue? If the restore doesn't work, do you think I should try replacing the battery on my own before paying the $550? Thanks!
