Zusammenfassung:	An infusion system and method configured to identify a break in static friction between a plunger and an infusate cartridge during an infusion of infusate for the purpose of providing a more consistent flow of infusate and promoting a more efficient use of energy. The infusion system and method can include monitoring of force between a drive mechanism and the plunger for a decrease in a rate of the force over time during actuation of the drive mechanism, thereby indicating a break in static friction between the plunger and the cartridge, and determining a low power consumption sleep duration based on an advancement of the actuator following the break in static friction.
