The Amazfit Balance Ultra is now officially on sale, available in black and black-brown strap options, targeting the premium outdoor smartwatch market.
Built with Grade 5 titanium alloy, the watch measures 51.8mm in diameter, 13.4mm thick, and weighs approximately 57g — lighter and harder than stainless steel. The front features a 1.5-inch AMOLED display with 480×480 resolution and a peak brightness of 3,000 nits, ensuring clear readability under direct sunlight, protected by sapphire glass for scratch resistance. It also includes a built-in LED flashlight for emergency lighting during outdoor activities.
Battery life is a standout feature. The 780mAh battery delivers up to 30 days in typical use and 50 hours in GPS precision mode, eliminating the need to carry a charger on long trips or trail races.
Health monitoring is powered by the BioTracker 6.0 sensor, supporting 24/7 heart rate, SpO2, skin temperature, stress, and HRV tracking, with active alerts for abnormal heart rates, low blood oxygen, and high stress. It also offers sleep analysis and female cycle tracking.
For sports, it supports over 180 workout modes with a dual-frequency six-satellite GPS module for independent route recording. As an official HYROX partner, it includes dedicated race modes, a hybrid training system, and auto-recognition for 25 strength training exercises. Rated at 10ATM (100m), it’s suitable for swimming and diving. Additional features include Bluetooth calling, NFC access and transit, 64GB offline storage, and 5 physical buttons (3 new ones on the left) for easier operation with gloves or wet hands.

ESD Protection for Smartwatches / Fitness Bands
The charging port and RF antenna are the two most critical high-risk zones—one safeguards the power supply, the other ensures communication. For all other areas, TVS diodes should be added incrementally based on their sensitivity levels.
- Type-C Charging Port: The most frequently contacted point; ESD strikes directly at the power IC. Requires low-capacitance TVS (≤0.7pF) with a clamping voltage ≤6.5V.
- RF Antenna (Bluetooth/WiFi/GPS): ESD coupling into the 2.4GHz signal chain causes communication drops. Requires ultra-low capacitance TVS (≤0.5pF) with ±30kV protection.
- AMOLED Screen FPC Interface: A major disaster zone for touch failure and screen flickering. Requires a TVS array + PCB GND stitching, passing 8kV contact discharge.
- Side Buttons / Crown / Home Button: The most frequently touched areas by users; ESD causes system crashes or false triggers. Requires low-capacitance ESD protection (≤1pF).
- Battery & Power IC: The ESD threshold of Li-ion cells is <50V; ESD can falsely trigger the protection board or burn out the PMIC. Requires secondary protection (TVS + PTC).
- Health Sensors (PPG/ECG/Accelerometer): ESD causes inaccurate heart rate readings or false AFib alerts. Requires an independent shielding cavity + signal line TVS protection.
- NFC / SIM Card Slot: Exposed metal contacts; ESD can burn out the NFC IC, causing payment or access control failure. Requires TVS diodes.
- Headphone Jack (if applicable): Audio CODECs have low voltage tolerance; ESD increases background noise or causes no sound. Requires low-capacitance TVS.
