Hum, maybe I meant the size of a key fob? It could be a bit thicker, I'd guess it would hold something like ~2000mAh. For just the radio, and for something that would be used only while on the go (otherwise you can use your home/your job connection), why couldn't that work as long as a feature phone, which could go for a week in a single charge?

In my experience with hotspots on the go, it's having to maintain the WiFi AP that kills their battery fast. Maybe there's a better protocol to run between the hotspot and other devices, although you'd need one that would also allow for 5G speeds.

If I were serious about designing this, I'd try:
- Bluetooth for control/signaling.
- Bluetooth for voice audio.
- WiFi AP in super reduced Rx/Tx power mode when not charging. The only requirement here is that signal is strong within a 3ft radius from the hotspot, and acceptable on a 6ft radius. It really shouldn't need more than that.
- WiFi AP in normal mode when charging.
- WiFi AP completely shut-off when the paired device reports that they have access to any other trusted wifi network.
My idea here is that for me at least, mobile data is truly a connection of last resort. Almost anywhere I go there is WiFi available. And the places where there isn't, perhaps I simply don't need an always-on fast connection?
