My Globe-issued iPhone X (256GB, space-gray) has been misbehaving for past six weeks or so. The first sign of trouble was when it suddenly overheated and died on me. Then it would go into random shutdowns, after which the battery--even if it had been, say, 80% charged, would be below 10%. I lived with this for several weeks--restoring, upgrading the software, trying the beta, restoring back to the basic software, reinstalling my apps one by one--and yet the phone would keep doing the same thing, sometimes 3X a day, and sometimes it wouldn't charge or recognize the charging cable (which worked perfectly with other iPhones). So yesterday I finally brought it to the PowerMac service center in SM North, after restoring it back to "new iPhone" status. I explained its problems--which of course the restored iPhone did not manifest on the spot. I had also wiped out the panic logs, which is apparently the first thing they look at. Anyway they ran another diagnostic test, which showed that everything was okay--except the battery, which failed. They said they would do more tests. Today I got a text message saying that the diagnosis was "SWOLLEN BATTERY" and that they would elevate the case to Apple to see if it merited repair/replacement or not. (How can it NOT, I wonder.) I Googled the "swollen battery" issue and found that it was an iPhone 8 problem, having to do with battery bloat (I observed no bloat, no physical symptom in the casing). Has anyone had these random shutdowns/restarts/overheating issues with their iPhone X? Let's start the discusion/reporting here. Apple might need to see that it's not isolated (unless it's really just my phone). Thanks!
