In Watch mode, the Garmin Foretrex 801 disables several features to extend battery life significantly. The primary features that are typically turned off or limited include:
- GPS Tracking: Continuous GPS usage is a major battery drain. In Watch mode, the device minimizes or disables GPS tracking to conserve energy.
- Heart Rate Monitoring: Real-time heart rate monitoring can be disabled, as it requires constant sensor activity, which consumes battery power.
- Bluetooth and Wireless Connections: Disabling Bluetooth prevents the watch from searching for connected devices, which can drain the battery.
- Notifications: Incoming notifications are often turned off to reduce the frequency of screen activations and processing power.
- Screen Brightness and Timeout: The display brightness is usually reduced, and the timeout for the screen is set to a minimum to prevent unnecessary power usage.
- Data Fields on Watch Face: Features that refresh frequently, such as seconds or heart rate data fields, may be turned off to limit screen refresh rates and conserve battery life.
By disabling these features, the Foretrex 801 can achieve extended battery life in Watch mode, making it suitable for prolonged use without recharging.
