Apple watchOS 7.3.1 resolves Power Reserve issue
The release notes read:
watchOS 7.3.1 addresses an issue that prevented some Apple Watch Series 5 and Apple Watch SE devices from charging after entering Power Reserve.
Housed in the Control Center of the Apple Watch, Power Reserve mode allows users to prolong the battery life when if it is not possible to charge the smartwatch.
Power Reserve lets you see the time on your Apple Watch while preserving your battery life. While your Apple Watch is in Power Reserve, press the side button to show the current time. In Power Reserve, your Apple Watch and iPhone won’t communicate, and you can’t access other watch features.- Apple
When the battery charge drops to 10%, the user is notified automatically via a prompt either to enable the feature or dismiss the suggestion. It’s very easy to enable and disable the feature:
- Swipe up on the watch face to access the Control Center.
- In the menu, tap on the battery percentage.
- Swipe the ‘Power Reserve’ slider to enable or disable the feature. Learn more about the feature here.
