Apple Addresses New iPad Battery Charge Issue
The new iPad's battery may show it as fully charged before it is. That's due to a cycling feature built into iOS.There are reports that the new iPad keeps charging beyond the point where the battery icon indicates it is 100 percent chargedwhich is actually a value-added feature that Apple Vice President Michael Tchao said has been built into the products operating system, iOS, for a while. DisplayMate analyst Ray Soneira reported that the iPad says it is fully charged when it is not. What is happening, according to Tchao is that the new iPad runs on a cycle where it fully charges, then discharges, then fully recharges in order to maintain an optimum charge. That circuitry is designed so you can keep your device plugged in as long as you would like, he told the technology blog AllThingsD. Its a great feature thats always been in iOS.
Apple promises 10 hours of battery life for the latest version of the iPad, which has yet to be given an official moniker Apple usually bestows upon the updated versions of its products. Yankee Group analyst Carl Howe told AllThingsD that battery charging is a complex process, the specifics of which are best left to engineers. Whats really subtle is that consumers think they understand that 100 percent means full, Howe was reported as saying. That might have been the case with older batteries, but todays batteries have microprocessors managing their charging. So 100 percent is whatever that microprocessor says it is its not any absolute measurement of ion concentration or anything.
