Find my draining battery overnight
So I recently got an iPhone 12 for Christmas and it been using (according to the battery in settings) about 100% of the battery overnight and it is very consistent. It wasn’t doing this when I got it and it only started about a month ago. I haven’t gotten around to turning it off to see if it will solve the issue but I also have an iPad that doesn’t have the problem at all. Just a month or 2 ago the overall capacity of the battery was 97% and now it’s 93%. Is there a solution and it anyone else having this problem?
iPhone 6s, iOS 15
