Amazfit T-Rex 3: A Big Watch with AI That Wants to Be Your Coach

The Amazfit T-Rex 3 has a lot going for it: a bright, big display, rugged build, and a battery life that lasts for weeks. But does its AI-powered coaching system really live up to the hype? Let's dive in and find out. Smartwatch for the Big-Wristed Crowd Right off the bat, this watch is designed for those who like their watches on the larger side. Think Samsung Galaxy Watch Ultra or Apple Watch Ultra 2. The 1. 5-inch AMOLED display is a real standout, especially with its 2,000 nits of brightness. It's easy to read even in bright sunlight, and the ability to switch to night mode with different colored light options is a nice touch. Battery Life That Won't Quit We all know the frustration of a smartwatch that dies after a day. Not so with the T-Rex 3! Amazfit boasts an 180-hour battery life in GPS mode, and in my testing, it lived up to the promise. Even with regular use, I only needed to charge it once every three weeks. That's impressive, especially for a watch with so many features. GPS Accuracy That Impresses The T-Rex 3 uses dual-band GPS and supports six satellite systems, which means it can track your runs, hikes, and bike rides with impressive accuracy. I tested it against other high-end sports watches, and it held its own, even in dense forests. AI Coach: Your Personal Fitness Guide? The T-Rex 3 comes with a built-in AI coach, Zepp Coach, that uses your data to create personalized training plans. It can also answer your fitness questions through a chatbot, Zepp Flow. This is a really cool feature, but it raises some questions: * How accurate is this AI-powered coaching? While it seems promising, it's important to remember that it's still technology. * Will it be able to adapt to your needs as your fitness level changes? * What happens if you have a pre-existing condition or injury? More Than Just a Fitness Watch The T-Rex 3 is also a capable smartwatch. You can connect to external sensors like heart rate monitors and speed/cadence sensors, use voice memos, and even reply to messages with your voice (though you can't initiate calls). The Bottom Line The Amazfit T-Rex 3 is a compelling smartwatch, especially for those who want a big watch with a long battery life and AI-powered coaching. It's packed with features and performs well, but it's important to keep in mind that its AI features are still evolving. If you're looking for a smartwatch that can be your workout companion and more, the T-Rex 3 is definitely worth considering.
