The back and sensors of the Xiaomi smartwatch

Xiaomi’s smart watch was present on my wrist for 6 days. During that time I did not feel discomfort when sleeping, bathing and in everyday life. It can, however, get caught in clothing as its dimensions are considerable.

As a great highlight in this T-REX we have a 1.3 inch AMOLED screen, circular and complete. The smartwatch appears to have an oleophobic coating as the screen glass tends not to be covered with fingerprints and other dirt.

It is a touch-sensitive screen, but we can only use the 4 physical buttons to enjoy all the functions. Something useful since this watch will be used outdoors, during training sessions and in the most varied conditions.

At the bottom we have all the optical sensors of the watch, the BioTracker and the charging points. Inside there is an accelerometer, gyroscope, geomagnetic sensor, in addition to heart rate and GPS.

The design will share opinions, whether you like it, or choose another smartwatch. IS gross, for outdoor activities and without fear of taking a few falls. However, it is as far as possible from being a formal watch, nor was that the purpose of Xiaomi.

That said, we have a well-built watch with a bright screen, great color and good resolution 360 × 360 pixels with great density. The result is sharp images, well-saturated colors and good visibility outdoors.

Ask for not having the screen always on (always-on), but when raising the pulse the display is activated. Alternatively, by pressing one of its buttons the screen will also wake up, it is worth mentioning that has automatic brightness adjustment.

The Amazfit T-REX is a good smartwatch with GPS, especially considering its price. Something that is applied in the monitoring of activities, accompanying the user throughout the exercise sessions. This is one of the watch’s strongest arguments.

The operating system, Amazfit OS, is based on gestures or swipes and we can only navigate with the physical side buttons. The user experience is good, with the clock being fast in all types of actions and navigation through the functions.

O delay between transitions it is minimal and we feel that the terminal is always ready to respond to needs. It is equally quick to enter the options as to start monitoring physical activities.

The watch has Bluetooth and Wi-Fi connection

Synchronizing the Xiaomi watch is easy and takes a few minutes.

The Xiaomi smartwatch has Bluetooth 4.2 and 5.0 connection, as well as Wi-Fi at 2.4 Ghz for, for example, downloading firmware updates. Unfortunately we cannot transfer music to its 40 MB of internal storage.

The Amazfit app is available for Android and iOS free of charge. From there you synchronize the watch, choose watchfaces, see activity reports, graphs that you can share on social networks and more product details.

The watch is charged using the included magnetic base, more specifically, via the pogo-pins or magnetic attachments. On average, it takes 2 hours to fully charge.

You have multiple notifications to show on the watch

AmazfitOS is very intuitive and easy to understand.

Amazfit T-REX displays notifications on your left screen. There you will have access to notifications push sent by the phone application to the watch. It is also from the app that you can define which applications can send these notifications.

Among the tested apps we highlight Whatsapp, Instagram, Messenger, SMS and the phone. The user cannot respond to notifications, but he already has a good information card, easy to access and to clean after consultation.

This point was a very positive surprise, especially when some more expensive models from Amazfit do not offer this option.
