Haven’t seen any battery impacts but I only installed this on my devices last week, on my ipad some days before. I didn’t install earlier than that because of battery issues reported on the watches. But the final release(s) have been fine.Yeah good call. I just turned off automatic updating on my iPhone. From early reports it looks like iOS 17 comes with a serious decrease in battery life so I don't plan to be an early adopter on this one.
