Amazfit Balance gets major update: HRV, Running Power, Race Training

The popular Amazfit Balance smartwatch is undergoing a significant transformation with a comprehensive firmware update. The software brings a host of exciting features, including heart rate variability, Running Power, half-marathon and marathon training plans and more.

Launched in September 2023, the Amazfit Balance succeeded the Amazfit GTR 4. This is the most high-spec Amazfit watch to date. Its features include a large circular AMOLED display, comprehensive health tracking, and an impressive battery life of up to 14 days.

Now, the latest firmware update is taking the Balance to new heights.

Features for athletes

The star of the show is arguably the inclusion of heart rate variability (HRV) tracking. This is notable as it marks a first for Amazfit smartwatches. HRV measures fluctuations in the time between heartbeats. It serves as a valuable indicator of overall health, stress levels, and workout recovery.

Athletes will also rejoice at the addition of running power metrics within outdoor and playground running modes. Running power provides a more responsive and comprehensive analysis of running effort compared to traditional pace and heart rate data. You can read more about the metric in our separate piece.

Marathon runners will benefit from the dedicated half-marathon and full marathon training plans now available within the Zepp Sports Coach. These plans provide structured guidance to help you achieve your goals.

Features for winter sports fans & more

Winter sports fans got some love, too. They will appreciate the addition of track navigation and ski maps for snowboarding and skiing. The update even adds bouldering and indoor rock climbing as new trackable sports types. Furthermore, the ‘Zepp Flow’ feature brings new insights, providing data on your physical and mental readiness, sleep, and activity levels.
