Cortex-M0 is the most energy-efficient processor in the Cortex-M family. Suppose a Cortex-M0 processor takes 100 uA (microamps) in the active mode, and 48 uA in the sleep mode. If the application puts the processor 50% of the time in the active mode and 50% in the sleep mode, and two button cell batteries power the processor, with a total capacity of 600 mAh. How long can the batteries last? (Thumb of rule: Battery Life = Battery Capacity in mA per hour/Load Current in mA *0.70).
