If you have an Apple Watch Series 4 or Apple Watch Series 5, Apple has good news for your battery life.
In the release notes for the second developer beta of watchOS 9, the company announced that it is improving the maximum battery capacity estimate for the Apple Watch Series 4 and Series 5. According to the release, the updating to watchOS 9 will recalibrate its battery capacity estimate automatically.
After updating to watchOS 9, your Apple Watch Series 4 or Series 5 will recalibrate and then estimate its maximum battery capacity more accurately.
This is great news for any Apple Watch Series 4 or Series 5 owner who felt their battery capacity estimate was wrong based on their battery life experience. Since the update seems to focus on these two particular models, Apple must be confident in its calculations for the Apple Watch Series 6 and Series 7, its most recent model.
watchOS 9 is still only available in developer beta, with the public beta expected in July. The new software will be available to all Apple Watch owners (well, at least Apple Watch Series 4 and later) in the fall.
