1. A method performed by a surgical system, the method comprising:
providing current to an ultrasonic instrument to put the ultrasonic instrument in a low-power state, wherein the current is below a current threshold at which an end effector of the ultrasonic instrument produces heat; and
while the ultrasonic instrument is in the low-power state:
determining a resonance frequency of the end effector of the ultrasonic instrument;
determining a temperature of the end effector based on the resonance frequency; and
displaying, on a display of the surgical system, a notification based on the temperature.
