Battery life is a critical factor for IoT devices. In this commentary, Brian Whitaker at Keysight Technologies examines how battery emulation and test software can help you accurately measure battery life and extend the battery life of an IoT device.

Battery life affects the cost and reliability of IoT-based infrastructure and is a key purchasing consideration for consumer electronic IoT devices.

Battery life can contribute significantly to the cost and reliability of the Internet of Things (IoT) infrastructure. While for consumer electronic devices, battery life is often a critical purchase consideration. Therefore, the fact the calculated battery life of IoT devices is often inaccurate is a significant issue for manufacturers.

One method to measure battery life is to divide the battery capacity in amp-hours by the average current drain in amps, which provides a time in hours. However, in the real world, this calculation is overly simplistic.
