Attributes

Remarks

FromIdAsync will return null if the battery controller does not exist and the deviceId value is well-formed. If the deviceId value is not well-formed, such as "AggregateBattery," then the method will fail with STATUS_OBJECT_NAME_INVALID.

You can use a DeviceInformation object for a battery controller to use that object's Id property value as the deviceId parameter in FromIdAsync to create a Battery object
