Apple brings battery recalibration tool to iPhone on iOS 14.5 beta

Battery health is a new feature Apple previously provided to users. This feature can detect the remaining battery life to avoid device instability due to low battery life.

In the latest iOS 14.5 beta, Apple has improved battery health for the iPhone 11 series. The main improvement is to solve the previous inaccuracy.

Apple stated that some users had previously reported that there was an inaccurate problem with battery health. After troubleshooting, Apple confirmed to “address inaccurate estimates of battery health reporting for some users.”.

iOS 14.5, coming later this spring, includes an update where the battery health reporting system will recalibrate maximum battery capacity and peak performance capability on iPhone 11, iPhone 11 Pro, and iPhone 11 Pro Max to address inaccurate estimates of battery health reporting for some users. Symptoms of this bug include unexpected battery drain behavior or, in a small number of instances, reduced peak performance capability. This inaccurate battery health reporting does not reflect an issue with actual battery health.

At present, the lithium battery used in smartphones will gradually age with the increase of use time, and when the battery gradually ages, its capacity will become lower and lower until it is scrapped.

Previously, Apple’s down-frequency gate incident was caused by battery aging, which was not enough to support the peak performance of the chip after aging, so Apple quietly restricted its frequency.

After being discovered, users believed that Apple deliberately restricted the chip frequency to stimulate users to replace new devices. For this reason, Apple was also subject to a class-action lawsuit to compensate a lot of money.

Subsequently, Apple’s new battery health function can monitor the usage of the battery and estimate its remaining capacity. When the remaining capacity is less than 80%, it means that the battery needs to be replaced.

In the latest update, some users found that the estimated data of the battery health function is inaccurate, that is, performance problems may also occur more than 80% of the time and affect the use.

After investigation, Apple confirmed this problem and fixed it in the iOS 14.5 beta 6 version. When users upgrade to the new version, the system will take several weeks to track and analyze.
