Google Play Console: the meaning of "Active Devices"

Question

I see it always differ from Installed audience and is mostly more. I am curious how this value gets calculated ?

I believe it's quite confusing as it has similar meaning as installed audience while it always differ and more surprisingly is always higher number. I was googling but could not find definition for exactly this anywhere.

Answer 1

Active devices are defined as:

An active device is one that has been turned on at least once in the previous 30 days.

Installed audience is defined as

The number of users who have your app installed on at least one device that has been turned on in the last 30 days
