Apple Support Document Explains AirPods Max Low-Power States

Apple Support:

If you set your AirPods Max down and leave them stationary for 5 minutes, they go into a low power mode to preserve battery charge. After 72 stationary hours out of the Smart Case, your AirPods Max go into a lower power mode that turns off Bluetooth and Find My to preserve battery charge further.

If you put your AirPods Max in the Smart Case when you’re not using them, they go into a low power mode immediately to preserve battery charge. After 18 hours in the Smart Case, your AirPods Max go into an ultralow power mode that turns off Bluetooth and Find My and maximizes battery life.

This jibes with what I’ve experienced, but it’s great to have these time frames documented. (I just asked for this a day ago.)

Also, you can check the battery status on the AirPods Max themselves:

If you press the noise control button when your AirPods Max are connected to power, the status light will turn green if the charge has more than 95 percent remaining, or amber if the charge has less than or equal to 95 percent remaining.

If you press the noise control button when your AirPods Max aren’t connected to power, the status light will turn green if the charge has more than 15 percent remaining, or amber if the charge has less than or equal to 15 percent remaining.
