I left it on the whole time - approx. one hour. I knew the route but was just trying it out as the phone is a new upgrade and the orange maps came as a free 5 day trial.
If you intend to just turn on the gps from time to time to check your route it may well do the trick. I don't suppose you'd want a mobile strapped to the handlebars anyways.
Even when driving to somewhere strange using sat nav I always like to look at the destination / route on a map just to get an idea in my head where I should be heading. Sat navs sometimes seem to take some weird and wonderful routes.
As an aside I also stuck the mobile on the dash and videod my drive home the other day - don't ask. That wiped the battery out pretty quick too.
