If the mouse is standard-compliant, it should be sending the battery level 
strength in usage 0x20 of device controls page (0x06).

Could you please obtain HID debug dump (CONFIG_HID_DEBUG + modprobe hid 
module with 'debug=2') and look at this usage both in the report 
descriptor itself, and also check whether it is present in the received 
reports?

Thanks,
