Same with me, totally annoying, after updating my phone to latest software my iPhone battery started to drain faster like before it would drain 50% in 6 to 8 hours and now it was draining 50% in 4 to 6 and most of the times phone was ideal and i was not using it. Thanks to another apple thread in this forum where I found a guide  How to Stop Battery Draining on iPhone After a Recent IOS Update where I got to know that Disabling Siri and search settings as well as journaling suggestions and the app privacy report that run in the background and can drain the battery fast even when you are not using your phone. I followed other solutions too and now my battery drains to 50% in 8 to 10 hours with the same usage.

Update: 3 days on from my first post I was hoping for things to get better (with a 'fix' released by Apple..?) but they've actually become worse.


My iPhone 13 Pro battery crashes within half an hour of taking it off the charging cable. I am honestly at a complete loss as to know what to do and currently using a cheap PAYG for essential calls when away from home.


I've attached a few screenshots to show what happens when I remove the iPhone from the charger…100% (supposedly) to 12% in 31 minutes, with no activity other than taking the screenshots. Battery health is still showing 100%!
