Amazfit has begun rolling out a fresh software update for the Amazfit Balance 2 smartwatch. Firmware version 6.5.13.5 introduces new navigation options, manual swim drill tracking, and several accuracy upgrades for runners and hybrid athletes.
New Map Navigation and Swim Drill Tracking
The headline additions in version 6.5.13.5 focus on helping users navigate and log specialized workouts more easily:
-
POI Navigation: You can now view your saved locations directly on the watch map and start turn-by-turn navigation straight from Points of Interest (POIs).
-
Pool Swimming Drills: Swimmers can now track non-standard exercises, such as kickboard sets or one-arm drills. The watch lets you manually mark when a drill starts and ends, then enter the exact distance covered so your total yardage stays accurate.
Sharper Heart Rate Tracking and HYROX Calibration
Amazfit has also refined several core fitness and sensor features under the hood. Runners should see improved heart rate measurement accuracy during workouts, and the watch now uses cleaner, standardized “Zones 1–5” naming across workout screens and settings instead of confusing labels.
For athletes pairing their watch with external gear, Helio Strap Pro calibration has been streamlined. The watch now calibrates the strap automatically in the background during standard HYROX Race and HYROX Simulation workouts, though custom simulations are excluded from this automatic process.
Cleaner Maps and Easier LifeLoad Logging
Everyday usability gets a boost as well. Map visuals have been polished with clearer contour lines and a better-proportioned map scale, making terrain easier to read at a glance.
Meanwhile, LifeLoad daily habit logging is now simpler to use, featuring clearer ratings, a new “Late Meal” event option, and custom timing when logging “Trouble Falling Asleep.”
Staged Rollout Underway
Like most Amazfit updates, firmware 6.5.13.5 is rolling out in phases. A first wave of Amazfit Balance 2 owners can install the update today through the Zepp app, while remaining users should receive it over the next few days.
