Apple Responds To New iPad Battery Kvetching

This is patently ludicrous. As part of the general, low-level kvetching about the new iPad’s battery is the complaint that it continues to charge after it hits 100% — which apparently makes people think that Apple is lying about how charged it is. Nevermind that experts in the field say that this is common to most modern consumer devices, Apple’s now had to weigh in to defend themselves. Talking to AllThingsD Apple VP Michael Tchao told them that once the new iPad fully charges, it will discharge a little, then top back up, and repeat this cycle, the entire time keeping a reading of 100%. Said Tchao:

“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.”

This allows the device to keep an optimum charge, and is actually better for the cell than keeping it at a totally full charge. AllThingsD also talked to Yankee Group analyst Carl Howe, who said:

“What’s really subtle is that consumers think they understand that 100% means ‘full’. That might have been the case with older batteries, but today’s batteries have microprocessors managing their charging. So 100% is whatever that microprocessor says it is — it’s not any absolute measurement of ion concentration or anything.”

In other words, stop bellyaching. The new iPad has an incredible battery life, considering what it is. People are just looking for a reason to complain.

    iPhones have been doing this for the past couple models. You can connect to iTunes, charge till it says 100% and iTunes will say it’s still charging. Not much difference between pulling it off when the phone says 100% and when itunes does.
