Description
Amazfit Balance 3 (Stainless Steel)
The Amazfit Balance 3 is a health and fitness smartwatch centered on the BioTracker 6.0 sensor, dual-band GPS with six satellite systems, and AI-powered Zepp Coach training plans for athletes who want advanced metrics beyond basic step tracking.
Display and build
A 1.5-inch AMOLED display reaches up to 3,000 nits brightness for legibility in direct sunlight. Sapphire glass improves scratch resistance, and this variant uses stainless steel construction for a premium feel (the Balance 3 line also offers a titanium option).
Training and sports
Official HYROX training and race modes support hybrid fitness racing. Advanced running metrics include VO2 Max, Training Load, and Lactate Threshold. Zepp Coach builds AI training plans that adapt to recovery status and training readiness. The watch supports pairing with external Bluetooth heart rate monitors, cycling power meters, and cadence sensors. More than 180 sports modes include smart workout recognition.
Health monitoring
BioTracker 6.0 enables 24/7 heart rate, SpO2, stress, and sleep tracking. RestoreIQ sleep analysis adds HRV and recovery insights. One-tap measurement covers heart rate, blood oxygen, stress, and breathing, with recovery status and training readiness tracking.
Battery, storage, and connectivity
Up to 21 days battery life on typical usage. 64GB internal storage, built-in microphone and speaker for Bluetooth calling, Bluetooth 5.2 and Wi-Fi, and 10 ATM water resistance for swimming and water sports.
Software and ecosystem
Runs Zepp OS with downloadable apps and customizable watch faces. Compatible with Android 8.0+ and iOS 17.0+. Syncs with Strava, TrainingPeaks, Google Fit, and Apple Health.
Common questions
iPhone support: Yes — iOS 17.0 and later; some health integrations may be richer on Android.
HYROX without competing: Underlying metrics still apply to general functional fitness training.
External heart rate: Bluetooth chest straps and similar monitors can pair for more precise readings during intense sessions.
