Amazfit Launches Zepp OS 6 Activity Sync on 2 Watches, Consolidating Multi-Device Data

Summary
Zepp OS 6 introduces Activity Sync, which merges daily steps, calories, standing and distance across multiple Amazfit devices through the Zepp app instead of keeping separate totals.
Only 2 models—the Amazfit Balance 3 and Balance Ultra—support OS 6 at launch, while Zepp Health says more devices, including the Balance 2, will follow.
HybridCharge also replaces BioCharge as Amazfit’s main readiness score, adding logged stressors such as illness, alcohol and jet lag plus post-workout perceived exertion.
The bigger gap is physiological syncing: Zepp Health has not confirmed whether training load, recovery time or Helio Strap workouts feed across devices, leaving Amazfit behind Garmin’s broader multi-device system.
