Third-party reviews

What we like about Amazfit T-Rex 3 Pro

  • Battery is rated at 17 days, and heavy use still lasts about a week.
  • Sapphire glass resists scratches better than ordinary glass.
  • ECG adds a heart rhythm check to the usual tracking.
  • Dual-frequency GPS keeps tracks steady under dense forest.
  • The 3000 nits screen stays easy to read in direct sun.
  • Built-in flashlight with a red mode helps on early starts and night trails.

What we don't like about Amazfit T-Rex 3 Pro

  • The large case feels heavy and bulky on smaller wrists.
  • Detailed sleep reports and AI features need a paid subscription.
  • The touch screen picks up false touches in rain and sweat.
  • Charging contacts do not always line up with the base.
  • No USB-C cable is in the box, so you need your own.

Verdict

Sapphire glass stands out on the Amazfit T-Rex 3 Pro, and it resists scratches better than ordinary glass. The battery is rated at 17 days, and in tests with heavy GPS use it lasted about 7 to 13 days. The screen reaches 3000 nits, so it stays readable in direct sun. It has an ECG, dual-frequency GPS that tracks cleanly under dense forest, and a built-in flashlight. The flashlight also has a red mode, which is easy on night vision. The watch is water-resistant to 100 m. The main trade-off is size: the case is large and can feel heavy on smaller wrists, and at 13.2 mm thick it adds bulk. It suits an outdoor person who wants a tough, well-tracked watch and does not mind a big case.
