New iPad needs charging beyond 100%

New iPad needs charging beyond 100%In order to fuel the various enhancements found in the new iPad, the battery is said to have 70% more capacity than that of the iPad 2, weighing in at a whopping 11,666mAh (hail Satan).

Now we’re hearing that the new iPad’s battery is quite demanding on the old charger, and is actually still sneakily charging after it claims to have reached 100%.

The news comes via Dr. Raymond M. Soneira, the chap behind Display Mate. Soneira told ArsTechnica via email: "I measured the power actually drawn by the AC Adapter and found that the new iPad continues to charge for up to 1 hour after it claims to reach 100 percent. This affects the battery run time if you stop charging when it says 100 percent.

“Other tablets and smartphones also lie about their charging status, so if getting maximum battery run time is crucial, people need to keep their devices recharging for longer than the screen claims."

With the new iPad, Apple went against the grain, releasing a device that’s slightly thicker than its predecessor. It houses a quad-core GPU, 2048 x 1536 display, and of course that big fat battery.

In the obligatory there’s-something-wrong-with-the-new-iDevice news, the new iPad is said to get kinda hot. Wow.

Well, interesting.
And it's NOT just the new iPad!!!
That calls for more research, doesn't it?

Yawn, more "news".. .Guess what, every iOS device still charges past the 100%, and - as the original article also says - "Other tablets and smartphones also lie about their charging status"

The difference is the battery on this one is so huge it does it for longer.

The % meter is a mathematical model, while users expect a % meter to increase linearly, the actual charging is all but that. This is simply a tolerance for the curve fitting that goes on.

No need to troll. It's an interesting little tidbit that's probably been posted on hundreds of sites. At least Mobot's articles have a nice amount of balance.

Exactly, blizz.
Especially, when modern smartchargers tell us to "disconnect charger now" - at a hundred percent.
Mr Marcelino, just because you already know stuff, doesnt mean we need to shut down the web. ;)

+1 to Jan and Blizz's comments. There's nothing wrong with educating people, remember, we're not all geeks ;).

An educational article would be titled something like "Tablets and smartphones charging beyond 100%" and would go into the reasons behind this.

Please don't pretend this is an educational article, it's edulinkbait at best.

Well I didn't know that the new iPad needed charging up to an hour past it displaying the 100% charged icon to actually be fully charged, before I read this article.

I was educated by the article, therefore the article is educational. End of.

I do agree that the headline is a tad cheeky, as, indeed, it affects many other devices.
It is nonetheless 'educational'...and there are few article on the webz that cover 100% ground - whatever 'issue'.

Read some of the questions visitors post here and elsewhere...you fail to appreciate what little things can make people struggle. And, correctly, our short piece contains a link to the source for further research.

Wired just tested various tablets and found that the Asus Transformer Prime ran the hottest at 98.5F after 30 mins of EA Games' Dead Space. It was followed by the:

Kindle Fire: 96.5F
Blackberry Playbook: 95.5F

and only then new iPad at 94F.

http://www.wired.com/gadgetlab/2012/03/new-ipad-versus-5-tablet-competitors-which-runs-hottest/

It's a very informative article too, where one learns that Zombies are at 70F.

I now look forward to the headlines comparing the Transformer Prime to hot coals and maybe some glove recommendations for handling it. Ha I forgot, it's not an Apple product so it doesn't get the same creative headline treatment.

Umm... What?

jcmarcelino,
Are you seriously suggesting mobot is biased towards Apple?

That is ridiculous.

Yeah...I wasn't quite sure of the relevance either...

My last comment was referring to the last paragraph of the article - the iPad runs warmer non-issue - already mentioned in 2 other dedicated articles here in Mobot.

If there's so much interest in reporting iPad temperatures surely the same should apply to other tablets.

blizzard7  Mar. 26, 2012 at 22:46

ZOMG! Mobot is biased against Apple.

No, frankly NOT. Cause nobody is buying other tablets. :p Hot or not.

Everything is a non-issue. You just need to ask the right person. There is more interest in the iPad.
It IS as simple as that.

In case you didn't notice: You are perfectly FREE to start your threads here on mobot in any category. We even encourage commenters to submit articles. Yes, you may even get paid for your work. Instead you exert all this energy because YOU are offended by a 3 paragraph mini-article's triviality?

Guess what, I'm not an Android fan, and I currently own no iDevice. However do I survive a day here what with the 3 or so SGS3-related stories that run here?

It can run outside of (aka, above) it's thermal specifications with perfectly reasonable usage, that's an issue. Yes, it won't melt your hand off or set fire to your sofa, but it may shorten the life of some components inside the iPad.

If my car's engine temp. was in the red (even if the car seemed to be running fine and wasn't burning anything obvious) I'd still call that an issue, wouldn't you? It'd still go back to Audi to be fixed as I wouldn't want it to suddenly die on me at a later date. You're telling me you'd just continue to use your car and hope that the issue wasn't actually an issue at all?

All articles on the Samsung Galaxy S III - a device that isn't even out, yet. http://www.mobot.net/search?search=samsung+galaxy+s+3

matt101101 / MOD  Mar. 26, 2012 at 23:16

Nevermind out, it hasn't even been officially announced yet...

jmarcelino  Mar. 27, 2012 at 00:12

Come on guys, do I have to draw a picture? I'm just fed up with this whole temperature subject and would like to get histeria level down a notch.

Apple gets electron ink by the boatload here over how the new iPad runs 5 degrees (centigrade) warmer. Why? Is there really nothing else truly interesting to write about?

Of course there is, there's a whole world of actual flaws out there to be reported. There's no shortage of other tech stuff to write about either - wasn't there a custom ROM series coming out or maybe a review of Android 4.0 with TouchWiz as I asked about the other day?

Sorry but running several articles parroting the other's iPad temperature nitpicks - to me - is just useless and lazy. Not that only Mobot does it, most of today's tech blogs runs this way (fortunately with exceptions). The whole culture of tech blogs sometimes just looks like one huge circle jk and innovative reporting comes more from politics and corporate shill-ing rather than any groundbreaking research.

@JanSt OK so where do I write an article? I only see a "ask a question" box. I'm not going to type a full article in there am I?

@matt Even if/when the iPad reaches 116F (anyone with one will know how hard that is to actually achieve) it won't harm the electronics. Any modern laptop runs far hotter than that with no ill effects, and stuff inside the iPad and a laptop is essentially the same. The only part that gets that hot on the iPad is the processor, which is on the opposite side of the iPad from the battery.
