Battery life

COROS is proud to provide the industry leading battery performance through COROS watches. By utilizing a carefully designed hardware system and a streamlined operating system, the sensors on COROS watches can provide an optimal and stable data tracking accuracy along with a highly efficient battery performance.

In Standby mode, the HR monitor takes a reading every 10 minutes. During sleep tracking, the HR monitor reads every 2 minutes. In workout modes, the HR monitor and GPS take a reading every second.

Backlight, vibrations and tones are main battery killers. When preparing for longer workouts, please adjust the settings accordingly. COROS watches don’t support the option to turn off sensors manually. During workout modes, Bluetooth is automatically disabled. There’s no airplane mode for COROS watches.

In order to prolong the battery life, please recharge the watch before the battery reaches 0%.

If you still need help, please contact COROS support.
