@JonQ as far as i know long term battery life is heavily influenced by how much and how frequent your battery gets depleted over the course of each day.
my theory is that if you can stop the actual battery inside the librem 5 smartphone from depleting and somehow have another primary source of power depletition (this one you can sacrifice in order to not have the hassle of having to remove the battery from inside the phone) - then you wouldn’t care if the battery inside the librem 5 is hot-swapable (it would be ideal but hey !)
i propose to just use the external BlackBerry Charger for Q10s NX1 hot-swap-able battery and just use a female micro usb to male usb-c adapter and tape it on the back of the phone if that isn’t to much of an inconvenience to you (better yet just use double sided-adhesive velcro). it can both charge and power at the same time if you use a secondary usb cable with a wall plug or directly connect to a powered usb port on the pc.
