Unfortunately advertised battery life isn't practical. Though maybe with software enchantments it could get there.

The GPIO port is accessible under the back cover so I could easily see add-on modules that could piggyback on. Design a small backpack to use the existing latch, add some tiny pogo pins and the module could be easily swapped out. A lorawan transceiver and a GPS receiver would be an excellent pair.

You'd need an additionnal micro and speaker, or at least some usb-c headset but yeah this give some ideas.

Also battery life would probably sink.
