“While the new iPad has come under some criticism for the way it handles battery charging, Apple says the device operates in the same manner as past iOS devices,” Ina Fried reports for AllThingsD. “The source of the confusion stems from how Apple manages the charging process from the point when a battery is very nearly charged until a user unplugs the device.”
“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,” Fried reports. “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.”
Fried reports, “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.'”
