If your charger can't keep your phone charged while in use, you need a better charger.
Basically, some chargers only give 0.5 amps rather than the full 1 amp. See the link above.
Remember though that a (properly designed and functioning) device will only pull as much current from the source as its power supply circuitry allows, so simply connecting it to a higher capacity charger isn't always a solution.
That point is irrelevant. Most if not al smart phones can an will take advantage of having a 1, 2, 3, or even 4 amp charger. The devices will charge off a .2 or .5 if not being otherwise used. But they will charge faster with more juice available. And .2 and often .5 won't keep up with even regular usage, let alone a nav app.
No device I've heard of will let a more powerful charger fry it, but having more juice available is a benefit and is thus highly recommended.
