Bluetooth has been broken on both editions of their Pro Max Phone (15 & 16). It cuts out and has all kinds of weird issues, but no fix has come for years now. This was why I always paid a premium for their phones, they did hardware and software well. Not anymore, their so focus has been on their processors.
This tends to be an Apple issue. They introduce proprietary thing and eventually unless your hardware supports said thing it will have a degraded experience in some way
Apple has the MFI program for these things. You can get certified and tested in relatively short order.
They also aren’t removing the original protocol support or anything like that.
What I will say is that I think they don’t devote as much QA resources to getting it right as they do their own protocols, hence the difference.
With Microsoft it was very different. They wanted to subsume or shutdown whatever they targeted with EEE
