Understanding Battery Performance of IoT Devices

Battery life is a constant concern for users of wearable devices, and it can be a challenging issue for firmware engineers to address. Factors such as battery performance in different temperatures, voltage fluctuations, and battery degradation over time make it difficult to accurately predict battery life. However, there are strategies that can help optimize battery life, such as measuring power consumption, tracking metrics, and aggregating data from a fleet of devices. It is important to capture metrics that contribute to power consumption, such as connectivity, peripheral usage, and CPU usage. By analyzing these metrics, engineers can identify factors that affect battery drain and make improvements to prolong battery life. In addition, aggregating battery life metrics across a fleet of devices can provide insights into overall battery performance and help address any issues that arise.
