The most-recent week we told you about a strange fact about the iPad 3 that it still continuous to charge even it get 100%. People reported that the fresh iPad in contrast charges up to an hour after it is charged until 100%. Other than this, we also came across news that the New iPad heats more than the previous iPad 2. This reason was understandable because the New iPad got a new battery which is more improved than the old iPad 2. The New iPad gives you about 10-hours of extreme fun. When the fun ends, the charging starts, The New iPad still charges up to an hour after its 100% charged.

This was a strange mystery until AllThingsD took a step on this and conducted an interview of Apple’s Michael Tchao. Tchao told Allthings D that this nothing new and nothing to be worried about because this an effect of trickle charging, which has been there in iOS from the start.

So, here’s how things work: Apple does in fact display the iPad (and iPhone and iPod Touch) as 100 percent charged just before a device reaches a completely charged state. At that point, it will continue charging to 100 percent, then discharge a bit and charge back up to 100 percent, repeating that process until the device is unplugged. 

Doing so allows devices to maintain an optimum charge, Apple VP Michael Tchao told AllThingsD today.

“That circuitry is designed so you can keep your device plugged in as long as you would like,” Tchao said. “It’s a great feature that’s always been in iOS.”

Like we told you before that the New iPad can give up to 10- hours of battery life, regardless the fact that when the person puts the iPad on charge/discharge and the trickle cycle starts. When the iPad reaches 100% and it is still charging, the iPad discharges and then starts to charge by its self. It is also assured that when a person disconnects the iPad from charging, the battery is shown 100% because the person shouldn’t be confused about his iPad that it is charging or not.
