The company added that even without placing it into the provided charging case, the AirPods Max is capable of lasting 72 hours on idle with Low Power mode activated. Exceeding this threshold will then trigger an even more aggressive power saving feature that disables its Bluetooth connectivity, as well as the Find My function. However, it was not detailed on how much longer the headphones will last in this mode. Apple claims that the 72-hour period is intended to allow users to track the headphones if lost or stolen.
Meanwhile, setting the audio device into its charging case will immediately activate the Low Power mode. Should the case run out of charges, the AirPods Max would enter the aggressive power saving mode after 18 hours, conserving more power when compared to the 72-hour threshold on its own.
