1.0 says:

  When a device has more than one instance of the Battery service, each Battery
  Level characteristic shall include a Characteristic Presentation Format
  descriptor that has a namespace/description value that is unique for that
  instance of the Battery service.

1.1 says:

  When a device has more than one instance of the Battery Service, each Battery
  Level characteristic shall include a Characteristic Presentation Format descriptor
  (Volume 3, Part G, Section 3.3.3.5 in [1]) that has the Name Space field set to
  ”Bluetooth SIG” and the Description field set to a valid value from the GATT
  Namespace Descriptors [4] and that is unique among all instances of the Battery
  Service exposed by the GATT Server.

1.0 was a mess and your anger over a poorly defined and relatively minor feature seems quite misplaced. Bluetooth interoperability has historically been a mess (still is from my experience). But go ahead be big mad that Airpods only play audio from third party devices and don't provide battery status in a way that adheres to a recent revision of the standard. Meanwhile I'm sure Sony would never use a proprietary format ever…

I had posted a reply addressing your points, but I don't think this discussion is productive and you don't seem to want to engage honestly with what I'm saying and stay on topic. So I'll just say have a good day.

You're lambasting Apple for not implementing part of a standard that hadn't been standardized.

Nope. Bye!
