True, since many Bluetooth headphones have replaceable batteries, even
by the manufacturer.

OMG, "ask nospam," the biggest fount of misinformation in this
newsgroup, is an amazing response!
The reality is that the Bluetooth standard does not have any direct way
of prioritizing connections. Maybe some future revision of the standard
will add that capability. iPhones _cannot_ add that capability. Nor can
Android phones. There's only a little that the phone manufacturer,
operating system manufacturer, or app developer can do to address this
issue. Even the Android app I referenced earlier, doesn't do much in
this regard.
Pairing Bluetooth devices in the priority order you want them connected
is how it's supposed to work now. The issues is that if a device with
higher priority is available during a periodic scan then the phone will
automatically drop the connection to the current device and reconnect
with the higher priority device. This makes sense. If you get in the car
with your Airpods, the Airpods connection should be dropped and a
connection the vehicle audio system should be made. Well unless you're a
passenger, not the driver, and want to use your Airpods in that vehicle,
in which case the driver's phone should automatically connect (and it
will, if it was the last phone that was connected). When I drive my
wife's car, with her in the car, her iPhone connects to the vehicle and
I have to manually disconnect it in the audio system, or have her turn
off her iPhone's Bluetooth.
What iOS and Android _could_ do, is to have a switch in the Bluetooth
Settings "Do not automatically disconnect currently connected Bluetooth
device when a higher-priority device is in range." That would solve the
original poster's problem. Or he could delete his iPhone's pairing from
the vehicle. But you'd have some people that turn that switch on and
then get upset when the phone doesn't automatically connect to their
car's audio system.
For my iPhone, the connection priority appears to be "what did it last
automatically connect to?" If I manually connect a device, when the
device that it last automatically connected to comes into range, then it
disconnects from the manually connected device and connects to the
previously automatically connected device. That makes some sense since
the largest usage, prior to wireless music quality headphones, was
connecting to a vehicle's audio system.
It would be nice to have a revision to the Bluetooth Standard that added
the ability to set prioritization rules, but that would be complicated
and non-techies would be confused. I suspect that when Bluetooth was
first created they never imagined the proliferation of Bluetooth
devices. Bluetooth was designed mainly for hands-free mobile headsets
and for hands-free calling through a vehicle's audio system. The low
bit-rate didn't matter for voice audio. The latest Bluetooth feature
"Auracast" will be great when it gets deployed, allowing broadcasting
audio to multiple Bluetooth devices.
