Hey, long term apple user and encountered first issue ever. My 10 months old iPhone 7 have started to randomly shut down and it can't be started again until plugged in to power. It doesn't matter the battery status, it happens even if its 100% and also even when it is actually plugged in. Also did a restore to get a clean iOS install, still happens. It also happens even if its cold or hot, temperature doesn't matter at all and even if I hold it close to the AC to really cool it off... Nothing seems to matter, it happens often and can't seem anything specific that triggers it. Cant find anything about this regarding the iPhone 7 and latest iOS 10.3.3 when I google either. Anyone have any ideas or experienced something like this?
