That would eat through the batteries. Which means you likely need a different battery, which means more bulk, which ultimately changes the entire value proposition, and now you may have well buy a cheap android phone.
This thing, while worn requires zero power. You only require power to rotate the image.

You can stretch the battery quite far that way. I did this to monitor temperature in an outdoor pool. Omega sell plenty of WiFi connected industrial sensors (with small batteries) that are specced to run for a year or so before a recharge. Usually they report measurements on the order of minutes. I also have a Bluetooth HRM which I've used for years (probably days of use, cumulatively). I've maybe changed the battery once.
