Frequently Asked Questions

How long can a battery-powered BLE device operate?

Battery life depends on duty cycle and connection interval. With proper power management using CH582's sleep modes, a device transmitting every second can operate for 1-2 years on a CR2032 coin cell. Extending the connection interval to 1 second or more significantly increases battery life. For beacon applications with 1-second advertising interval, battery life can exceed 2 years.

Optimize connection interval and use sleep modes for maximum battery life. Contact our FAE team for power optimization guidance.
