I doubt it.
Since my last response I contacted Apple Support because I started experiencing a lot of disconnections with a the new GPS-like device I mentioned above and it was fairly annoying.
They did a "scan" both while I was on the phone with them and also when I subsequently went to the Genius bar the day after and they confirmed that both AirPods and iPhone's hardware are
perfectly ok.
The Genius Bar guy agrees with me that this must be a software issue. He suggested for me to do a factory reset of the phone
without restoring from a backup, that is what I was trying to avoid as I have quite a lot of stuff on the iPhone.
Anyway, I did.
Freshly resetted iPhone 13, with just my iCloud account (messages, calendar, contacts, wallet, notes, shortcuts, synced only) and whatsapp seemed to work ok.
I had two calls while walking around my neighbourhood, one on FaceTime, one on Whatsapp. Total almost one hour and no disconnections.
Then, the evening after I re-added most of the apps I had, manually.
Did not reinstate VPN settings and/or app testing profiles I had on that phone.
Morning after I had a Google Meets call, the AirPods dropped connection almost immediately and started the disconnect/connect dance.
I wanted to smash the phone against the wall but resisted
Again, same day I had disconnection from the gps device.
In the evening another call, 20 mins in my place no issues, as soon as I left from the front door, AirPods disconnected.
In my case there is definitely something that triggers disconnections of bluetooth devices while I walk/ride (driving/CarPlay not affected) around my place.
I removed the Philips Hue app. Today
bluetooth seems to work ok.
Also, when I resetted the iPhone I did no add back my "Home" in homekit, as I always doubted that would cause connection issues.
I'll keep testing app by app...
Allow me to say, this is
annoying as ****. And a massive waste of time, and Apple isn't helping.
But I'm not gonna spend one grand on a new iPhone to still have the same issue... have to solve this or switch to Android, that I'd rather avoid to be fair...
PS: to add, I never had issues with CarPlay (a lot of other users with similar BT issues did). CarPlay works perfectly for me and used it on quite a few different cars over the last 3 years sans issue.
