Battery Life Estimation Example

ZS1100A is designed to accurately measure energy consumption of low-power/IoT devices - establishing a current profile for the given device. This current profile can then be used by the host software to estimate the lifespan of a particular battery were it to be used in the device. This update walks through the process, using a wireless mouse as the target device. Read the full update.
