REVIEW – I’ve been using smartwatches since 2013 (the Pebble!), moving on later to models from Motorola, Apple, and Ticwatch. The Amazfit T-Rex promises up to 21 days of battery life while still delivering all the key features you’d want in a smartwatch, so I was excited to try it out!
What is it?
The Amazfit T-Rex is the latest offering from a company that has released many quality watches with longer-than-average battery life. It has a 1.3 inch AMOLED display, multiple military-grade water and shock resistance ratings, phone-free GPS workout tracking, rugged design, and smartwatch capabilities.
What’s in the box?

Design and features
The Amazfit T-Rex Smartwatch is made of rugged plastic with a soft silicone band. The buttons are metal, the screen slightly indented to prevent scratching. This is a large watch, so even on big wrists, it looks big.
I’m a larger person, and there were still plenty of larger spots, so this band should truly be one-size-fits-all. The band is removable with tools, and the body is water-resistant to 50 meters. It’s a nice soft silicone band, with a decent amount of stretchiness, which keeps it snug against your wrist for the always-on heart tracking, while not feeling tight.
Sensors and connectors on the back include the optical heart tracking sensor, and charging connectors. The charger snaps into place via magnets, which I found convenient and easy. The watch has an easy-to-use touchscreen interface, and also has 4 dedicated buttons, which I really like.
I installed the Amazfit app on my Google Pixel 3 XL (The Amazfit app is available on both Android and IOS), which was quick and easy. A quick firmware/GPS update later and I was off the ground running. I tested the heart tracking while doing both treadmill and outdoor workouts, and it seemed to be spot-on.
The AMOLED display is bright and vibrant, even outdoors in direct sunlight. You can opt to enable an always-on display at the expense of many days of battery life, but I found the lift-to-wake function to work perfectly for me – even though this same function has bothered me on previous watches I’ve tried. It’s snappy enough to not be annoying on the T-Rex, and I especially like that you can schedule when it is enabled (so I don’t blind my partner when rolling over in bed at night).
The app is pretty basic and easy to use while offering all the key functionality I’d look for in a smartwatch app. You’re able to customize which notifications appear on the watch, change settings and watch faces, initiate workout tracking, and view historical reports on your heart rates, workouts, and sleep tracking.
I wish the app directly integrated into other health and fitness services, but you can use 3rd party apps to sync to these other services (I tested one that perfectly synced all my data over to Google Fit).
The battery life was excellent if you’re not using GPS too much. GPS and always-on display will reduce your battery life to about a day or two, but I left them off and in a week of testing, I only used about 15% of the battery, so it’s on track to exceed the advertised 21 days on a single charge.
What I like
- The build quality
- The rugged design and water/shock proof ratings
- The battery life
- The cost
What I’d change
- Integrate with more services for health and fitness tracking
- Tool-less watch band change
For me, this is nearly the perfect smartwatch. I prioritize battery life over everything else, I can’t stand a watch dying on me! The Amazfit T-Rex ticks off all my needs and most of my wants, at a good price point.
