Just how much are you using your phone if you are turning it off between uses? You shouldn't drain the battery down that fast. If your riding anywhere other than CT or St. Johnsbury, VT then you generally can find plug ins at McDonalds that you can use and can use the free wifi to save internet usage on you phone bill. Pretty much most of CT doesn't have plug in at McDees. I needed the plug in real bad in St Johnsbury last summer as I rode into town after dark after my headlight had ran dead on me and I knew my original plan was going to have me getting home the folowing night after dark. Ended up changing the plans and got home before sunset instead.
