Apple Watch SE, where’s “battery health”
Settings ? Can’t find status of battery.
Apple Watch SE, watchOS 9
Question marked as
Battery charge level is available as a complication to selected watch faces.
Here are all the watch faces and their available complications: Apple Watch faces and their features - Apple Support
You can also check the battery level manually via Control Center. Here's how: Check your battery and charge your Apple Watch - Apple Support
Note that the above all refer to battery level, not battery health. Alas, the Apple Watch doesn't have a means of telling us the health of its battery.
Hope this helps.
