[QUOTE="Raz0rEdge, post: 1339880, member: 110816"] All batteries have two components, voltage and current. So when you plug the iPod into the charger, it gets a spike of voltage which ends up causing a spike into the battery capacity and the current comes along a little slower. After some time, the voltage tends to normalize and the current steadily increases. Once you read the 80-90% range, both current and voltage begin to taper off until it reaches what the battery considers to be a fully charged state. That being the case, it is completely normal for the battery to go from 20% to 50-60% in about 20-30 mins, but not last long since the current hasn't come along for the ride. Also realize that if you plug your iPod to the wall, the chargers are sucking anywhere from 1.5 to 2 amps of power and that can charge the battery pretty darn quickly. I can go from the 20% warning sign to a respectable 75% or more in about 20 mins and do some quick things before putting it back on charge for longer to reach full charge. Apart from the calibration method that cwa107 suggested, you should probably only disconnect the iPod from the charger when it indicates that it's reach full charge, as indicated by the plugged in sign..
