The latest firmware—3.39.0.4—brings navigation, Helio Strap support, and audio cues
Amazfit continues to enhance the Balance 2, expanding the watch’s navigation toolkit with a new Route Planning feature and a suite of training and usability upgrades.
The update allows users to create routes directly on the budget smartwatch or within the Zepp app, with planned courses syncing across devices for outdoor activities such as running, hiking, and cycling.
This builds on Amazfit’s existing mapping support, which has gradually improved with recent updates, bringing the Balance 2 closer to the navigation experience offered by more established sports watch brands (and its own higher-priced devices, like the T-Rex line).
Beyond route planning, the firmware also introduces Exercise Sound Cues, enabling workout alerts through the watch’s speaker or paired headphones, and adds swimming heart rate support when paired with the Helio Strap.
Additional refinements include improved vibration feedback during workouts, clearer map visuals with added route detail, updates to Zepp Coach training plans, and system optimisations to deliver more stable battery performance.
The update is rolling out in phases, with availability varying by region, and can be installed through the Zepp app once it reaches a compatible device.
The Wareable take: Amazfit continues to close the navigation gap
Route Planning is a meaningful step forward for the Balance 2—and signals Amazfit’s growing focus on outdoor and endurance users rather than purely lifestyle tracking.
The ability to build and follow routes without relying on a phone brings the Balance 2 closer to the functionality long associated with Garmin, Polar, and Suunto devices, particularly for runners and cyclists training on unfamiliar terrain.
While Amazfit’s navigation tools still lack the depth and polish of high-end rivals, steady software updates like this suggest the company is narrowing the gap.
For existing Balance 2 owners, this update reinforces the brand’s strategy of improving capability over time, making the watch a more credible option for users who want structured training features without moving into premium pricing tiers.
