How does a higher wattage Charger affect battery life?
The power rating of a charger has no bearing on the life of the battery nor the consumption of power by the device. A higher wattage charger only means it can supply up to the specified amount of current, not that it will push that amount of current to the device. Current is drawn, not pushed.
