Amazfit T-Rex 3 Pro Smartwatch - 44mm

Navigate to Settings > System > Reset on your watch. Please note that this will erase all data and settings from the device.

The T-Rex 3 Pro has a 10 ATM water resistance rating, making it suitable for swimming and shallow-water diving.

You can use many of the watch's features, such as activity tracking and basic timekeeping, without a smartphone. However, for full functionality like notifications, data syncing, and app management, a paired smartphone is required.

Firmware updates are typically delivered through the Zepp app. Ensure your watch is connected to your phone and has sufficient battery, then follow the prompts in the app's device settings.

The T-Rex 3 Pro supports a wide array of sports modes, including running, cycling, swimming, hiking, strength training, and many more, designed to cater to diverse athletic activities.

Under typical usage conditions, the battery can last for up to 24 days. Heavy usage, frequent GPS activity, and high screen brightness will reduce battery life.

Ensure the watch is adequately charged. Connect it to the charger for at least 15 minutes and try turning it on again. Check that the charging contacts on both the watch and the charger are clean.

Ensure you have a clear view of the sky when starting GPS activities. Update the watch's firmware and GPS system data via the Zepp app. Avoid starting activities indoors.

Restart both your smartwatch and your smartphone. Ensure Bluetooth is enabled on your phone and that the watch is within range. Unpair and re-pair the device in the Zepp app if problems persist.

Reduce screen brightness, disable always-on display if not needed, and limit background app refresh. Check for any third-party apps that might be consuming excessive power. Ensure firmware is up-to-date.
