Cortex-M0+ is the most energy-efficient processor in the Cortex-M family. Suppose a Cortex-M0+ processor takes 100 HA at running mode, and 50 HA at sleep mode. If the application puts the processor 50% at running mode and 50% at sleep mode, and the processor is powered by two button cell batteries with a total capacity of 600 mAh. How long can the batteries last? (Thumb of rule: Battery Life- Battery Capacity in Milliamps per hour/ Load Current in Mill amps * 0.70)
