Battery drain, overheating, and performance issues after updating iPhone 11 Pro to iOS 18.6.1

I have updated recently my 11 pro to 18.6.1

iPhone 11 Pro was released in 2019, SIX years ago. Have you ever paid Apple to replace the battery in your phone? Batteries are consumable parts and after six years, your battery health is likely heavily degraded, which would logically cause the symptoms you're describing.


Open the Settings App > Battery > Battery Health - is it at 80% or less, the battery needs to be replaced. You can schedule a battery replacement at your closest Apple Store Genius Bar for about $100.
