Your iPad will charge the fastest if connected to an power outlet. If you connect it to a computer for charging, depending on the computer, the iPad may not start charging until the computer is idle or "asleep." The charging time for any battery operated device always depends on how many times the battery has gone through the drain-charge cycle. For the relatively new iPad version 3, it may be as short as 30 minutes but again, depending on the condition of the battery, may take several hours to get a full charge. Also, keep in mind that the battery charge icon is not a direct measure of how much charge is left but a software interpretation of battery charge. In other words, it does take into account what you are doing so that the iPad can give you an appropriate warning of "5% charge" if you continue what you are doing.
