Music Playback
The Amazfit Stratos has 4GB of internal storage, allowing you to store music directly on the watch. Connect Bluetooth headphones to the watch for phone-free music listening during workouts or daily activities. Transfer music files to the watch via a USB connection to your computer.
Water Resistance (5 ATM)
The watch is rated 5 ATM, meaning it can withstand pressures equivalent to a depth of 50 meters. This makes it suitable for swimming and showering. Avoid using the physical buttons underwater, as this can compromise the water seal.
Maintenance
Cleaning Your Smartwatch
Regularly clean your watch to prevent skin irritation and maintain functionality. Use a soft, lint-free cloth to wipe the screen and watch body. For stubborn dirt, slightly dampen the cloth with water. Avoid using harsh chemicals or abrasive materials. Ensure the charging contacts on the back of the watch are clean and dry before charging.
Charging Best Practices
- Use only the provided charging base.
- Avoid exposing the charging base or watch to extreme temperatures during charging.
- Do not charge if the watch or charging base is wet.
Strap Replacement
The Amazfit Stratos uses a standard 22mm watch strap. To replace the strap, locate the quick-release pins on the underside of the strap where it connects to the watch body. Slide the pin to detach the strap. Attach a new 22mm strap by reversing the process, ensuring the pins are securely seated.
