That was the case on the old Motorola StarTac. One battery was attached to the top of the flip, and then there was a larger battery that could be clipped onto the back. Both would power the phone so as long as one had power you could swap the other.
Nokia n900 could do it live, with a charger connected instead of a second battery.
You disabled the watchdog, because root access was officially supported, turned the brightness way down, connected the charger, and finally swapped the batteries.
my headset does this, I’m spoiled by it and I’ll never go back. I’m fully ok with putting up with some of the issues with the headset exclusively cause of this feature. It’s so nice
I’ve used two headsets that done it, the Arctis Pro Wireless and turtle beach stealth pro, I highly recommend the Arctis Pro wireless over the turtle beach though as the Arctis Pro wireless was a seemless swap, where the turtle beach has a 10-15 second delay swapping battery.
I read somewhere about a phone that had 2 batteries, that way you could swap batteries with the phone remained turned on during the process!

Can you share the model name of your headset?

Used to be somewhat common as I recall back with flip phones (yes Im old.)
New shiftphone at least has a replaceable battery iirc.
I’m pretty sure taking out the battery of a feature phone would turn it off instantly.
The old ThinkPad T480 has this: an internal battery plus a hotswappable external one
Yeah my T460s has an internal and external
