The power consumption per bit transfer in all I3C modes is more efficient than I²C, due to the use of push-pull (vs. open-drain) and strong pull-up signaling.

Further, I3C can save considerable device power through higher data rates (because the device can be put back to sleep sooner), built-in configuration and control (without intruding on the main communication protocols), in-band interrupt (IBI) as a low-cost wake mechanism, and the ability for Slaves to shut down all internal clocks while still operating correctly on the I3C bus.
