How iPhone calibration works in iOS 14.5



Apple introduced another notable change in the latest iOS 14.5 beta – iPhone 11 battery calibration. The new feature provides an updated, more accurate reading of the device’s maximum battery capacity and top performance, and can solve unexpected battery operation. And in rare cases, it can lead to free battery replacement. Stay tuned for a hands-on look at how iPhone battery calibration works.

9to5Mac first discovered the new iPhone calibration feature in the iOS 14.5 beta code that led us to the Apple Support document that was just released.

In particular, the new iPhone battery calibration is only for iPhone 1

1, 11 Pro and 11 Pro Max, at least for now.

The feature first became available in the developer and public iOS 14.5 beta 6. If you want to test it before the public iOS 14.5 release this spring, you can see our full guide here to install the public or developer iOS beta (also includes Apple View unlocking for iPhone and 217 new emoji).

How iPhone calibration works in iOS 14.5

  • After installing iOS 14.5 beta 6 on an iPhone 11, the battery calibration process starts automatically
    • It can take up to a few weeks to complete
    • It can fix “unexpected behavior of battery operation or, in a small number of cases, reduced peak performance”
  • To check the status, go to Settings > Battery > Battery health
  • You will see the new “Important message” about the recalibration at the top
    • “The battery health reporting system calibrates for maximum capacity and peak performance. This process can take a few weeks. ”
    • The recalibration “will occur over time with normal charge cycles.”
  • Apple says you will know that the process was completed when the alert at the top of the Battery Health section is gone (new Maximum capacity and peak performance will be displayed)
  • If the recalibration finds “significantly degraded” battery life, a battery service message is displayed

Free battery replacement, extended warranties and more

In a “small number of cases”, Apple says that iPhone calibration of the battery will not succeed and a “new battery service message will appear.” In the rare cases, the message will say “An Apple Authorized Service Provider may replace the battery free of charge to restore full performance and capacity.” Apple notes that “this does not indicate a security issue and the battery can still be used.”

Apple also recommends waiting for an agreement with a store or other authorized supplier until the recalibration process is complete.

Finally, warranties can be extended to cover the potentially week-long recalibration process, and reimbursement may be possible for those who have previously paid for a battery service outside the warranty after seeing “the message about battery-powered health or experiencing unexpected battery behavior.” In either case, contact AppleCare.
