Poor Battery Health and calibration on iPhone XS iOS 15.1
I have been using XS for almost 3 years now and updated to latest iOS version. The battery Health shows its at a healthy 80% capacity but starts lagging and shuts down when the battery nears 20% mark. It wasn’t an issue with iOS 14 but have been facing these problems since updating to iOS 15. Any other person facing similar problems? This needs to be addressed with a software update I believe
