Apple says iPad battery charging works as intended
Responding to a recent analysis of the new iPad's battery, Apple has revealed that its charging system works as intended to ensure an optimum charge.
Concerns about the iPad's battery arose last week when an analysis was publicized claiming that the new iPad "prematurely" reports that it is fully charged by two hours. Dr. Raymond Soneira of DisplayMate claimed that the iPad actually finished its charging cycle some two hours after it reports a full charge.
That's by design, Apple's Michael Tchao said to All Things D on Tuesday. All iOS devices, including the new iPad, will display that they are 100 percent charged just before the device reaches a fully charged state. The device will then continue charging, then discharge a bit, and recharge once again — a cycle that will continue 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."
Apple's battery percentage display is simplified so that users are not confused by the constant cycle of charging and discharging while a device is plugged in. But Apple's approach allows all of its iOS devices to maximize their potential battery life.
Apple has boasted that the new iPad offers the same 10-hour battery life as its predecessor, even with the inclusion of a new quad-core graphics processor and 3.1-million pixel Retina Display. The new high-speed 4G LTE model also offers 9 hours of battery life when using a wireless network.
In particular, the Verizon model of the new 4G LTE iPad can serve as a mobile hotspot for more than 24 hours when sharing a high-speed data connection with external devices over Wi-Fi. That's upwards of five times longer than most standalone 4G LTE hotspots.

But the experts said it was a bug...
What makes them an expert.
Apple said you can get up to 10 hours on a charge. If 100% as indicated gives you that, where is the issue. Where is Apple at fault for over promising etc
Now there is an answer for those wondering why they only get 7-8 hours of battery time.
You guys need to take a chill pill.

I love these rare slaps in the face by Apple(when they expose a particular author as clueless).
It's a great little feature(trickle charging) and apparently one oblivious to tech blogs.

Actually, you have it backwards. Apple didn't overpromise, they overdelivered.
According to some reports I've seen, if you unplug your iPad as soon as it hits 100%, you get 10 hours (as promised). If you leave it plugged in for a few more hours, you get 11-12 hours.

Again 11-12 hours of what? Gaming, wifi, movies?
Amazing all the things Apple has to do to educate the market in response to those looking to find fault with their new products.
As sickeningly pathetic as it is it's also not a bad place to be as it's a clear sign that Apple is so far ahead of the competition.

Insider source says internal quota for charge time had to be met, so they 'modified' the display computer to have it say 100% before it was done charging). Easy, huh?
If you want a real answer, do a test with an iPad 1 and iPad 2 and see if it has the same behavior in the percentage display...

A scandal worthy of -gate proportions!

It seems to me these guys are out for public acknowledgement more than anything. It is more of a "look at me, I'm so smart" kinda play. It is like the obsession with the power draw of the unit which is very dependent upon the backlight. It is pretty common knowledge that for a given technology smaller pixels require more light intensity in the backlight.
Apple just rose to the occasion to deliver the best possible results in this display and made no excuses for the additional power draw. That people want to turn this engineering feat into a negative is curious to say the least.
I believe this may be a very slight deception by Apple to make it appear to charge faster- which would likely be a point on the iPad's reviews (considering the much larger battery). Granted, it is somewhat justified by Apple- that last 2 hours is a trickle charge done for the health of the battery- they could make it charge much faster at the expense of the battery.
Again, file this one under 'no story here'.. but sort of interesting none-the-less.

Ok. I am going to test it. I will write a script that searches Google and every time it brings back the results I will select at random a word on the page and do another search. l'll be repeating that every 5 seconds. I will set the auto lock to never on the iPad and let her rip. After it shuts down, I'll check my server logs to see the time of the last access of that script to determine the battery life. That should work.
I'll report back later.
