    Welcome to Android Central! It depends on the size of the battery, the maximum amperage of the charger, and the available current from the power source. A charger with low maximum amperage (e.g., 0.5 A) will take longer to charge to full than one that's 2.0 A. Charging from a computer USB port (which provides low current) will take longer than a wall outlet.

    And, unless the battery's been virtually killed (use it until the phone shuts off, give it 15 minutes, turn the phone on until it shuts off, etc.) 7 hours should be more than enough. But leaving it plugged in longer won't hurt it - charging stops wwhen the battery is fully charged even if the charger is still plugged in. (I've had phones that I put on charge and forgot for months. No problem except to the electricity bill.)
