Are there any features that are not affected by Ultra Low Power Mode on the Apple Watch Ultra 2

1. GPS tracking: While the frequency of GPS updates is reduced in Ultra Low Power Mode to conserve battery, the GPS functionality itself remains enabled. This allows the watch to continue tracking workouts and activities, albeit with potentially reduced accuracy compared to standard mode.

2. Heart rate monitoring: The watch can still measure heart rate during workouts and activities, but background heart rate measurements and notifications are disabled.

3. Workout tracking: The Workout app and basic workout metrics like time, distance, and calories burned are still available. However, advanced metrics that rely on frequent sensor readings may be less accurate.

4. Fall detection: For safety purposes, fall detection continues to work even when Ultra Low Power Mode is enabled.

5. Time telling: The watch can still display the time, which is one of the core functions.

6. Emergency SOS: The ability to call emergency services via the Emergency SOS feature is not affected by Ultra Low Power Mode.

So in summary, while Ultra Low Power Mode disables many advanced features and sensors to maximize battery life, it still retains core functionality like GPS tracking, heart rate monitoring during workouts, fall detection, timekeeping, and emergency calling. This allows the Apple Watch Ultra 2 to continue being useful for extended outdoor activities even with limited battery.
