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.

Hello,
all batteries degrade over time. Even new ones, it’s completely normal and nothing to worry about. You can learn more about your battery health with this guide iPhone Battery and Performance - Apple Support.

Thanks Drake, I’m aware that batteries degrade over time.
The issue I’m having now is a sudden change in battery loss since the upgrade!
Thanks Drake,
are you saying then that battery calibration has made the battery discharge quicker and charge slower? (That is what is happening), thabks
No, this just means that you get a more accurate battery health experience.
Okay, so going back to my original point - why is my phone discharging noticeable quicker that prior to the latest IOS update?
iPhone 12 Pro Max battery drain increased after iOS update
