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.
- 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?
