Amazfit has just released a major software update for its flagship smartwatch, the Amazfit Balance 2.
The new firmware version 3.30.0.2, rolling out globally through the Zepp app, transforms the Balance 2 from a capable fitness tracker into a professional-grade training companion.
This Update introduces TrainingPeaks integration, a dedicated Ski Machine mode, and useful Digital Crown shortcuts—three upgrades that make the watch faster, smarter, and more athlete-friendly than ever.
If you’ve been waiting for the Balance 2 to reach its full potential, this is the Update that truly unlocks it.
Looking for a deeper dive into the watch’s capabilities? Check out our Amazfit Balance 2 Full Review to see why we loved it even before this update.
1. Pro-Grade Training: TrainingPeaks Sync Finally Fixes Data Gaps
The biggest highlight of the Amazfit Balance 2 firmware update is the new TrainingPeaks integration. You can now sync your completed workouts, recovery metrics, and performance data directly from the watch to your TrainingPeaks account.
That means no more exporting data manually or relying only on the Zepp app. Structured training plans, TSS scores, and Intensity Factors can now flow seamlessly to your coach or dashboard—just like they do with top-end sports watches from Garmin or Suunto.
Amazfit has also added support for Intervals.icu, a popular tool among endurance athletes for tracking long-term fitness, fatigue, and form.
Together, these integrations make the Balance 2 a serious tool for cyclists, runners, and triathletes who want pro-level data without paying premium watch prices.
Crucially, this integration is currently available for non-China region accounts, and Amazfit has promised faster data syncing for accounts outside of China.
2. New Ski Machine Mode – Track Indoor Cross-Training
For athletes who mix in off-season or indoor training, the new Ski Machine mode is a welcome addition.
This workout profile is designed specifically for tracking indoor ski trainers, capturing your cadence, calories, and effort with improved precision.
It ensures that your ski sessions and cross-training workouts are logged correctly, giving a more complete view of your overall fitness activity.
3. Instant Access: Digital Crown Shortcuts Deliver Essential QoL
Amazfit has also overhauled the Digital Crown functionality for easier, faster navigation.
- Rotate Up: Opens the Notification Center instantly.
- Rotate Down: Opens the Control Center (for flashlight, brightness, airplane mode, etc.).
No more swiping through multiple menus—these Digital Crown shortcuts make the watch feel snappier and more intuitive.
It’s a small change that improves day-to-day usability, especially during workouts or when wearing gloves.
4. Quality-of-Life Enhancements
Along with the big features, version 3.30.0.2 also adds several smart refinements that make the Balance 2 more comfortable to use every day:
- Volume Zone Control: Adjust sound levels separately for media, alarms, and workout alerts.
- Custom Sound Settings: Choose different tones for calls, notifications, and alarms.
- Text Size Adjustment: Change text size from the settings menu for better readability.
- New Always-On Display Faces: More watch face options to match your style.
These small touches make the Amazfit Balance 2 feel more polished and personalized.
5. Precision Fixes: GPS, Treadmill & BioCharge Accuracy Improved
The latest Update also focuses on accuracy and performance—ensuring the watch is not just smarter, but more reliable:
- GPS Tracking: Enhanced algorithms now deliver smoother, more accurate route maps.
- Treadmill Data: Improved cadence and pace detection for more reliable indoor runs.
- BioCharge Logic: Refined body-energy calculations for more accurate recovery feedback.
- Workout Navigation: Smarter waypoint and slope alerts, with more explicit voice guidance during route tracking.
- Recreational Diving: Upgraded interface, improved vibration feedback, and optimized decompression logic for a safer diving experience.
Together, these improvements make every workout—whether on land or underwater—more precise and meaningful.
