The display is always-on and is built tough with scratch- and damage-resistant Corning Gorilla Glass 3. The watch face is customizable with over 100 different options available through the Amazfit app. While they do not state the nits brightness, the display is still bright and easy to read even in direct sunlight. You can even customize some parameters on your watch face to show battery percentage, steps, calories and more.

Sensors and Tracking

The Amazfit T-Rex Pro Smart Watch has a variety of sensors and tracking features to monitor your health and fitness. It has a heart rate monitor, blood oxygen saturation measurement system, and sleep tracking. It can track over 100 different sports modes including running, cycling, swimming, and hiking. The watch is also equipped with GPS, GLONASS, Beidou, and Galileo satellite systems for accurate tracking of outdoor activities. 

Here’s data from one of my running sessions tracked by the Amazfit T-Rex Pro. The device captures extensive metrics, highlighting its appeal to running enthusiasts. It records data like average stride, maximum stride frequency, and average cadence. While some of these metrics may not be particularly meaningful to me, they are undoubtedly valuable for dedicated runners who seek to optimize their performance and track their progress in detail.

Battery Life

The Amazfit T-Rex Pro Smart Watch has an ultra-long 18-day battery life with typical use and up to 40 hours with continuous GPS tracking. The watch charges quickly with a magnetic charging cable that attaches to the back of the watch. The battery life is impressive and allows for extended use without having to worry about recharging frequently.

For my kind of usage, I am able to get about 10 day battery life with 10% life on the watch before I need to recharge. Here are my settings:

  • AOD from 8am to 10pm
  • Hiking and Cycling activities 3 times a week with each session lasting about 3 to 4 hours
  • Brightness Level: Auto
  • Screen-on duration: 5 seconds
  • Health detection frequency: 1 minute interval
  • Sleep breathing quality monitoring: On
  • All-day Stress Monitoring: On
 

One thing I’ve noticed is that some downloadable watch faces can drastically drain the battery. I experienced only 3 days of battery life until I switched back to the default watch face, which resolved the issue.
