Apple addresses iPhone 15 overheating with a new iOS 17 update.::A new iOS 17 update from Apple that’s intended to fix reports of overheating iPhone 15s is now available. Apple acknowledged the problem over the weekend, blaming it on software problems.
I’d guess so but have you fully powered off and on your watch? I had this same issue, down to sub 10% by 8pm, and power cycling got it back to where I’m at 40% right now, a bit past 8.
Yeah, I had done a full restart, but that didn’t really help.
HOWEVER, since the latest iOS update that happened this week, I have seen the battery on the watch be better. Last night about 10pm I was at 30%. So maybe the phone was trying to talk to the watch a little too aggressively? Not sure. I’m hoping they figured it out, though.
