Apple Clarifies on New iPad's Charging Process
Contrary to Dr. Rayond M. Soneira's findings that the new iPad had an inaccurate battery-charge display algorithm, Apple stepped in to clarify that there is nothing wrong with the charging process.
According to AllThingsD, Apple's Vice President of iPad Product Marketing Michael Tchao explained that the iPad will display the battery status as fully charged just before it reaches the completely charged state. Thereafter, the iPad will continue charging to 100%, then discharge a little and charge back up to 100%. This process repeats itself as long as the device stays plugged in.
AllThingsD - “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.”
Tchao added that the same battery charging process is implemented across the entire range of iOS devices including the iPhone and the iPod Touch, and he believed that this process enables the iOS devices to maintain an optimum charge.
There have been numerous battery-related issues reported since the launch of the new iPad. American magazine Consumer Reports revealed that the new iPad could not charge under heavy processing and confirmed earlier reports that it runs warmer than the iPad 2. Users also found that the iPad takes a longer time to charge due to the larger battery capacity. Based on our review of the iPad, it takes an estimated five hours for a full recharge.
