5 Tips for Optimizing Battery Drain on IoT Devices

Application Notes

Powering the IOT revolution

The widespread success wide spread of IOoT applications is visible in the number of devices we use every day: smart-phones, tablets, e-readers, GPS units, wearable patient monitors, heart-rate monitors, and many more. Some attribute this success to the long-awaited convergence of highly integrated technology, wide bandwidths, application rich content, and attractive pricing.

Of course, the insatiable demand for anytime, anywhere access leads to end-user expectations that increase the pressure on product designers. As an example, visit any product-review page and one of the biggest issues --or opportunities --becomes clear: battery life.

The power challenge stems from two shared issues. One is the is long periods of standby operation between bursts of intense RF activity. The resulting current drain is pulsed with extremely high peak current, low duty cycle and low average values. Accurately measuring the profile of dynamic current drain can be difficult and challenging with many of today’s existing tools.
