iPhone 12 Pro Max battery drain increased after iOS update

Hi, updated to the latest IOS update on my iPhone 12 Pro Max, and battery drain is significantly increased. It also takes longer to charge. Checked battery health (phone is 5 months old) and has now reduced from 100% to 97%

anyone else had this - needs fixed!

This is most likely because your battery health was recalibrated with that update, there wasn’t a sudden drop. Your battery recalibrated to give you the most accurate battery information and that’s what you are seeing now.
