Hi, Same problem here. iPhone XS. battery capacity: 99% issue started somewhere with update to iOS 14.2. i’m observing that GPS is draining battery in my phone. “Find my iPhone” is checking each time my position (when I will open safari, start using phone, open any app). I see the icon on top of the screen. When phone is turned into low power mode it is not checking position each time. It works normally as it should be. In my opinion bugs are somewhere with gps that’s why it’s draining battery a lot in our phones (old). wife is using iPhone 12 and no issues. The same with iPad Air and iPad Pro 2020. Also not observed on iPhone 8.
