watchOS 9 introduces battery recalibration for Apple Watch Series 4 and 5

watchOS 9 was showcased alongside iOS 16 and macOS Ventura during the WWDC22 keynote. Since then, we are already in the second betas for developers of all these operating systems. Many of the features that were introduced are now available to developers and will be available to the general public when Apple launches public betas in a few weeks. One of the novelties of watch OS 9

is the incorporation of a battery recalibration system for Apple Watch Series 4 and 5. Thanks to him battery life estimation will be much more accurate than in watchOS 8.

In iOS 15.4, Apple also integrated a similar battery recalibration system for the iPhone 11. Thanks to this system the device is able to recalculate and optimize the battery level,

in addition to offering more accurate range data, which is also essential when considering a change of device or even battery.

After updating to watchOS 9, your Apple Watch Series 4 or Series 5 will recalibrate and then estimate its maximum battery capacity more accurately.

The same will happen with watchOS 9. According to the notes of the new Apple operating system which is in beta mode, Apple Watch Series 4 and 5 will recalibrate their batteries the first time they start up.

After the calibration is complete, watchOS 9 will display the maximum capacity estimate more accurately, getting closer to the actual data.

This process will be automatic and the user will be able to consult the final result, although he is unaware of the internal process that is taking place. What we do know is that the process could take a few weeks, just like it did with iOS 15.4 and the iPhone 11 a few months ago.
