I generally put my phone in Airplane Mode when I ride so I don't consume power as the phone attempts to connect to changing cell phone towers and various WiFi points. When I stop for food I will reconnect and check (maybe). Besides, when in bear country, you may also be in a phone dead zone.
Of course this may be a generational thing as I don't see it as important (or even good) to be on a phone leash. Many times I leave home without the phone as I grew up when there were only land lines.
