Last week, several publications picked up on a story about the new iPad charging past the 100% level. Curious to learn more about the situation, AllThingsD contacted Apple to learn more about why this charging issue occurs. And here was the what they learned, citing Apple executive Michael Tchao…
“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.
‘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.’”
This pretty well settles any concerns about the new iPad charging past the 100% level, because it is in fact a normal feature that has been part of the iPhone, iPod touch, and iPad for several years.
