I have bad near vision and need to have items near my face to read. My distance vision is OK with glasses. Could a wrist mounted iPhone case work during a DS ride? To navigate, I would simply look at the display on my wrist.

This wrist case would not easily allow a PowerLet cord, so the iPhone must run on batteries. How long will an iPhone battery last when receiving GPS signals?
