Can I Leave My Iphone 12 Charging Overnight. As you can see your iPhone 13 actually adapts to your behavior. Optimized Battery Charging is on by default when you set up your iPhone or after updating to iOS 13 or later.

Even though you can charge it anytime and you can back up its data anytime that process becomes invisible if you stick to charging your phone overnight. Will this damage the battery quicker. I use my 29 and 90w brick for overnight charging since day 1 of my iPhone 11 and the battery still sits at 99.
Even though you can charge it anytime and you can back up its data anytime that process becomes invisible if you stick to charging your phone overnight.
I just got my iPhone 8 today and im about to charge it for the first time. There can be invisible non-app processes particularly photo processing that will use battery overnight. Thats why you should keep this in mind while charging your iPhone overnight when you cant monitor its temperature. When Optimized Battery Charging is active a notification on the Lock screen says when your iPhone will be fully charged.
