Recalibrating my battery

Apple stopped recommending battery "calibration" over a decade ago.

If you post why you think the battery needs attention, we may be able to help in a way that does not harm your phone or its battery. Be sure to include whwhichr iPhone this is, if not the iPhone 7 running iOS 15 that is shown in your equipment line.

Remember, all rechargeable batteries are wear items; they have a finite life span. An iPhone 7 could be as old as 8 years and I would expect the original battery to be rather tired by now.

• Does your question mean you already replaced the iPhone battery?
• Was the replacement done at an Apple Store or Authorized Apple Service Center?
  • Yes. Return there and seek assistance if required.
  • No. Apple will no longer support this iPhone.
