Right now, when your Apple Watch enters Power Reserve mode because its battery is almost out of juice, the time appears on the face as a simple digital clock — and that’s it. The wearable’s other features are temporarily disabled. But Cupertino may expand Apple Watch functionality in low-power mode in the upcoming watchOS 9, according to a new report.
In addition, updates could include new workout types, additional workout metrics, expanded sleep tracking and new watch faces.
