Since its launch in September 2024, T-Rex 3 has been well-received by users. We have also adhered to a monthly update rhythm, continuously providing users with the latest OTA version to continually enhance the product's user experience and add new features. The December version is truly epic, bringing multiple upgrades at the system level, in interaction, and in motion items.
1. Zepp OS 5: A Brand-New Visual and Interactive Experience
The operating system has been fully upgraded to Zepp OS 5. Compared with previous versions, the new system introduces a redesigned user interface and improved interactive effects, offering more natural, fluid navigation and a cleaner, more intuitive layout. The result is a significantly enhanced user experience that feels clearer, smoother, and more enjoyable.
2. BioCharge App Launched: Scientifically Quantify Physical State
Understanding your physical state is the key to effective training and recovery. The new BioCharge feature, which replaces the previous “Readiness” metric, analyzes data such as your daily sleep, heart rate, and activity levels to clearly show your all-day energy consumption and recovery. With intuitive, real-time energy scores, BioCharge helps you plan your workouts and rest more scientifically, so you can train smarter and recover better.

- To better reflect real outdoor backpacking conditions, we’ve added a new Rucking workout mode. Simply select your pack weight before each hike to record energy expenditure more accurately and train with greater precision.
- A new Mountain hiking workout has been added. This workout can track altitude changes, distance, and climbing data throughout the entire journey, meeting your diverse mountain climbing needs.
- Additionally, workouts such as Trail Running, Outdoor Hiking, Mountaineering, and Climbing now support load settings, making your exercise data more accurately reflect the true intensity of your activity and helping you improve more efficiently.
