Apple Reveals Details of iOS 14.5 Battery Recalibration on iPhone 11
The iOS 14.5 update will add a battery recalibration system for the iPhone 11 series to fix drifting data.
Currently in its sixth developer beta, the upcoming iOS update will address an issue where the iPhone 11, iPhone 11 Pro, and iPhone 11 Pro Max experienced unexpected battery drain or a drop in performance.
An Apple support document notes that the inaccurate battery health reporting doesn't reflect physical battery health.
The iPhones in question will recalibrate maximum battery capacity and peak performance capability during regular charge cycles. The company cautions that the process may take a few weeks to complete. The displayed maximum capacity won't change while the phone is recalibrating.
Affected users will see a message indicating that the recalibration is in progress when navigating to Settings, tapping Battery, then Battery Health. When the process completes, the maximum capacity and peak performance capability will be updated in that same Settings section.
In a small number of cases, the recalibration may fail and alert the user that the phone will require service. The company says that an Apple Authorized Service Provider will replace the battery for free to restore full performance and capacity in those unusual cases.
The iPhone maker says the issues don't indicate a physical safety issue and that the battery is still usable.
Apple added the iPhone Battery Health section to the Settings app in iOS 11.3. The changes arrived as a transparency measure in response to revelations that the company was throttling CPU performance on older devices. Apple's throttling is done to ensure smooth operation, but some customers took offense to the fact that slowdowns were occurring without user transparency.
