Ok, so I was slightly offit's only 6 years old. In addition it wasn't 15 minute charging, it was only a few seconds: http://www.sciencentral.com/articles/view.php3?article_id=218392803
It seems it has more to do with nano technology lagging behind and not taking off as rapidly as we had hoped it would. Economies of scale are not kicking in for this tech quite yet.
Here is another one about 10 minute car battery charging (also from MIT): http://www.engadget.com/2006/02/17/mit-researchers-invent-new-hybrid-car-battery/
You can literally go on for days reading about all these batteries that haven't panned out. Everything from those nano tubes, to new metals, to fuel cells, to using viruses and other biological materials to create crazy new batteries that just about power themselves. But you hardly see them hitting the market.
Juvenile would be picking fights with someone on the internet. You seem to know so much about me, such as what would satisfy my apparent bloodlust for the battery industry. I was simply making an observation. My original comment was light-hearted and good-natured. I never called scientists any names. Near the end I was joking about how they are often at odds when trying to receive funding. Sir or Madam, I suggest you take everyday conversations on the internet a little less serious.
Yes, "MIT or someplace like that"that's exactly where it was. In reality MIT seems quite involved with new battery science and research. It's quite fine if you think MIT is bland, but I was not picking a name out of thin air that I've heard of before to try to sound smart on the internet. See the above links and read them. It's ridiculous that I have to go find an article from 6 years ago to prove a point. Lighten upand think next time before posting. It might keep you from being embarrassed again
This is the primary reason I don't post on here as much any more. So many new members have joined since the iPad became popular. Many of them are an insult to basic human intellect.
I'd rather have a significantly lighter device that has a run time of 8-10 hours (but have to charge it daily).

Exactly my initial thought. Would be nice if the 16GB iPad 2 still for sale got this little upgrade.

You are missing the big picture. The answer is not to pack a hundred cells into a device.
The answer is to redefine the technology used to make batteries.
The basics of LiPo and NiMh rechargeable batteries hasn't changed in 30 years and the NiCd has been around 100 years.

My intellect? LOL, you're talking like this forum is your father's property!
If you had a reason not to post here, why are you now? You having joined earlier than others doesn't certify you as a very cultured and literate gentleman. I've seen this arrogant "pride" among quite a few 'veterans' here: it's mediocre.I didn't mean MIT was bland, I merely suggested that you don't even seem to know concretely where the technology you're referring to originated, who the people that invented it are, what the current status of its research is and so on. Instead, you just want to do one thing: rant. Light heartedly or otherwise. Empty pots always make the most noise.
Complaining like an unappreciative school girl and then acting adept and sophisticated with big boy words — I've seen plenty of you
I didn't mean any offense to begin with and I still don't, I just suggested that you could show a little more recognition towards what you're already getting. But please, carry on. The homework won't do itself.

Duh! Of course it takes longer to charge! If it is 70% larger in Watt-hours I will take 70% longer to charge. It's called physics. Apple could design bigger chargers that charge faster but that's not their priority.
The battery is also physically bigger and heavier than the ipad2's.

Charging glacially slow on my iPad 3
Until reading this post and the allied thread, I thought that there was a fault on my iPad 3 or Dexia Green cable. I changed chargers from an old 10W one for my iPad 1 to the one that came with the iPad 3, just to make sure that was not an issue. It did not seem to be charging at all via USB and after 15 minutes on the charger, has gone up a single percent. At this rate, it is going to be a 12+ hour charge from say 40% (where I usually end up at the day's finish) to full. My iPad 1 charged from that to full in about 3 to 4 hours. It may be that the battery is still in the process of forming and subsequent charges will be quicker. I think that Apple needed to bring out a quicker charger - say 20 or 25 watts.

Have you tried to charge the 4th gen ipod touch on the 10W iPad charger? Must take 15 - 20 minutes for a full charge! A bigger charger would help the new iPad so I wonder if there are aftermarket USB chargers with a higher charge rating.
I have a pair of iPhone 3's (UK and France) that charge up very quickly on the 10W charger (what a stupid idea making the 5W and 10W chargers identical). I have put Dymo tape labels on my 5 and 10W chargers, so I don't mix them up. It may be that the 30 pin connector can only handle 2 amps (10W), in which case a higher wattage charger might damage it.
Maybe Cook should walk over to Tesla and see if they can license the Supercharger tech. Although it might take a couple years to engineer that down to a level a tablet could handle.
Funny how I again come back to this comment after looking through my quote notifications to see how enormously wrong you turned out to be. No magic or increases in tech to be found. Just the same old techslow to charge, poor at dissipating heat. Furthermore my original rant about battery technology has turned out to have merit, although it has been somewhat blown out of proportion by the media.
What it boils down to is you're just a troll who can't admit when they're wrong. Need proof of your trolling? BOOM:

That is trolling to the max. And you thought my original post was just noise filling the forum? Let's take a good hard look at your recent gems:

On a serious note, competitors beware. $100 bn is a LOT.
But go ahead thinking that your comments are adding so much to this forum that you've been a member of for all of one month. I'll be doing real worklike designing website and application interfaces using primarily Apple hardware. So while I'm a huge Apple fan, I feel like the amount of time and money I have invested in their products gives me the right to voice a potential concern every now and then. But even then in the OP, my concern wasn't with Apple, but with the battery industry as a whole.
These aren't the ONLY comments I wrote here but boy oh boy you're a real nut job! I'm not even gonna read whatever crap you wrote because frankly I don't give a flying rat's hairy ass about 13 year olds whining and then getting offended on the internet. Just do me a favor and stop being a freaky stalker, okay?

Nut job? I didn't start the flaming on the internet. 13? You've got to be kidding me. At this point, I honestly believe it's the other way around. Stalking? It's called click on your name, view more posts. Copy paste. Takes 30 secondsand was only done because you first called the validity of my own comments into question. But being a forum newbie I doubt you realize how easy that is to look up. And yesthose were the majority of your comments since this thread. Useless tripe from a mindless buffoon. Don't take offense just because I pointed out that you're a troll. Oh wait, that's exactly how a troll would react. "NA NA NA NOT GONNA READ YOUR RESPONSE BECAUSE I'M ALWAYS RIGHT NA NA NA" Grow up, fool. If you can't take criticism, then you shouldn't criticize others. As for me, I fell for it and fed the troll. You'll see no more responses from me, and I will never revisit this thread.
I feel the pain guys, charging the new iPad takes a considerable amount of time. I hope Apple considers reducing the power usage of the iPad 4, so that I don't have to charge it every day. I'm organizing a list of tricks to optimize the charging time here. I hope it is useful for some of you.
I have to say though that because of the properties of the battery, charging it until 40% takes considerably less time than charging it fully, which probably has something to do with the properties of the LiOn battery that the iPad has. It has to be said that for the health of the battery, it is smart to charge it 100% and let it drain 100% from time to time. This way the battery will last longer.

It feels good to lash out on random people, doesn't it?
