I think this would be simply about adding a column showing battery level / charging state / health in the "/admin/devices" listing.

This is critical for administering the devices at our company. It would be so much easier to manage device refreshes and determine device refresh cycles if I could see which devices have batteries that are beginning to fail and budget for those to be replaced. I could also see which departments based on the types of device usage are harder on the batteries and perhaps they need to be replaced sooner vs other departments which might last far longer and better than anticipated and could go longer without refreshing and maintain device performance. With this feature in MDM this could be very simply exported to excel and filtered quickly.
