iPhone 11 is slowing down after each iOS update!

iphone 11 slows down after each os.


My iPhone 11 is in good condition but lately it is getting slower with each update Apple is pushing out. Is this intentionally done to kill older models? 🤔

iPhone 11, iOS 26

  • What is your Battery Health percentage at Settings > Battery > Battery Health?
  • Have you ever replaced your battery yet, it would be unusual for an original battery to still be functioning normally on an iPhone 11.
  • If you did have it replaced, was it done at an Authorized Apple Service Provider, or did you purchase the iPhone 11 Refurbished where it may no longer have a genuine battery?


Battery Health will always go down and you can't prevent that. That will have an effect on phone performance, no matter what iOS version is installed. When the battery health is below 80%, you have a choice of either spending about $100 on a battery or putting that money into a newer device. The battery on an iPhone 11 is only expected to last 500 charge cycles before it should be replaced.
