Amazfit Balance 2 Firmware 3.35.0.5: New Features, Fixes & How to Update

Amazfit has just dropped a massive firmware update (v3.35.0.5) for its flagship Balance 2 smartwatch.

While most sites simply list the patch notes, we’ve broken down exactly how these new features work and how to set them up to maximize your battery life and training.

What’s New in Version 3.35.0.5?

This update focuses on three pillars: Rugged Fitness, Real-time Recovery, and UX Efficiency.

1. New Professional Fitness Modes: Rucking & Hiking

The Balance 2 is moving closer to the T-Rex rugged series with these additions:

• Rucking Mode: Specifically designed for those training with weighted vests or backpacks. Unlike the standard “Walking” mode, this algorithm accounts for additional load to provide a highly accurate calorie-burning and cardiovascular strain metric.
• Mountain Hiking: Optimized for vertical gain. This mode uses the barometer more aggressively to track rapid changes in altitude and trail difficulty.

2. The BioCharge Revolution

“BioCharge” is Amazfit’s answer to Garmin’s Body Battery. This update introduces:

• 24-Hour Trend View: You can now see a graph of how your energy recharges during sleep and depletes during stress or workouts.
• Morning BioCharge Card: A summary that greets you upon waking, telling you exactly how much “fuel” you have for the day ahead.

3. Long-Awaited Utility: Native Screenshots

Finally! You can now capture your watch face without using your phone.

How to take a screenshot: Simultaneously press the Circular Crown and the Lower Button. The image will sync automatically to your phone’s gallery via the Zepp App.

Technical Optimizations: Better Battery & Accuracy

Amazfit didn’t just add features; they fixed the “under-the-hood” issues that users have been reporting on Reddit:

• Outdoor Run Battery Fix: The GPS algorithm has been tuned to reduce power consumption during long-distance runs.
• Weather Reliability: A new data source and a fix for refresh logic address the “Weather Not Updating” bug that plagued the previous version.
• Portuguese Language Fix: Full localization cleanup for Brazilian and European Portuguese users.

Comparison: v3.35.0.5 vs. Previous Version
