The iPad’s battery issue began when a DisplayMate report said the tablet’s battery continued to charge after the meter on the screen read 100 percent. This opened up a can of worms that led to reports that excessive charging would damage the iPad’s battery. Vice President of product marketing Michael Tchao finally put an end to this iPad battery controversy with an official statement from Apple.
Tchao told AllThingsD, “That circuitry is designed so you can keep your device plugged in as long as you would like. It’s a great feature that’s always been in iOS.” So you can plug in your iPad and let it charge to your heart’s content without worrying about the battery.”
According to a Wired report, the iPad will charge to 100 percent and then release a small part of this charge. It will then charge fully again and repeat this process until you unplug it. Customers don’t have to worry about this terminal part of the cycle because the iPad battery will read 100 percent. The device will deliver its guaranteed 10 hours of battery life and there will be no damage to the battery.
