Im looking for a phone with no or limited screen that is as small as possible that has very long battery life.

It could connect wired/wireless to video glasses, handheld screens, TVs, or whatever for video. It could connect to headphones, cars, etc for audio.

IO could be done on the screens, finger sensors for gestures, voice command, or even neural commands.

essentially remove the screen from the phone and let me choose a visual IO method based on my needs.
