Is it ok to watch video while my iPhone is plugged into a wall charger, or use gps while it's plugged into car the car charger? I am a newb to the phone. Both things, especially the gps seem to suck power. Thanks
Depending on the source of the power, and the apps you are running, you may find your device still loses power while plugged in - albeit at a slower rate. I think screen brightness and 3G/GPS use cause this the most.
Ran into this on a 5 hour drive. GPS was sucking battery, so I had to keep exiting out of the app for it to charge up a little bit. Rinse & repeated.
