The PIP-Watch is a battery-powered device that will be continuously on, hence the average power consumption is one of the most important engineering aspects.

In this post I will go through two simple steps of optimizing CPU power – sleep modes and lowering the clock frequency. In a next separate post we will look into Bluetooth module power.
