      Technically, yes. But you would have to leave it parked for weeks. I would be far more concerned about the charger or phone battery overheating – and that probably won’t happen, either.

      it will drain it down a lot after about three or four days because mine did this once but it shouldn’t hurt it for a day or two and if you have a real good battery it wont hurt it at all the newer battery’s will take the drainage,and still start,,good luck,i hope this help,s.

      As stated above, yes it could, but it depends on a number of factors. if you’re having trouble with the battery and think it might be the phone…it probably isn’t.

      you would have to have it on the charger for a very long time. Or have a very poor battery in your car. You would have to try very hard to kill the battery with a cell phone.

      no because the car chargers have a built in unit that once the phone is charged it will stop charging. Kind of like a light switch it cuts off the power to it.

      Not unless your battery is already worn out.

      Charging my ipod touch twice without ever starting the truck caused me to need a jump… so yes… But.. I have charged it once several times before without issues… My truck battery is 3 years old so a new one would obviously be better…
