Have we heard anything on charging time?

[DS3]

We could be in for some long charges if the rate is the same with the much larger capacity.

Though I'm no technical expert on batteries so perhaps there is reason to believe it will be similar.

Thankfully my iPad rarely got below 50% anyway and I use it a lot.

Same 10 watt charger. It's a bigger battery than the MacBook Air 11", which requires a 45 Watt charger. I'm betting that this will take forever to charge, and will be nearly impossible with the iPhone charger which I used to carry for portability's sake.

I've gotten into a pretty good charging cycle with my iPad 1st gen. It's very rare that I have to charge anytime but overnight. The thing could take 7 hours to go from 0-100 and I'd be okay with it.

 

[vega07]

If the charge time is nearly doubled, that would be ridiculous. It already takes about 4-5 hours for 0-100% with the iPad 2.

 

[big samm]

I know with my first gen ipad it takes 3 hours from 0 to 100%. Im surprised people are saying the ipad 2 takes 4 to 5 hours that seems a eternity!

Just plug it in every night before you go to bed and it will be 100% charged when you wake up. I have been doing this since iPad day one and have never had to worry about charging time.

A larger wall wart won't equate to faster charging time since Lithium-ion's require control circuits that dictate the charging speed.

 

[iHeartsteve]

I dont mind the 4-5 hr charge time but any long would be highly inconvenient

 

[Stealthipad]

Not a big deal. DO you people sleep?

Just put it on charge before you go to sleep. DONE!

I also find it very interesting.
The battery has been increased 70% in size and we still get a 10W charger.
I hope it doesn't mean we have to wait 70% longer for the iPad to charge. The iPad 2 - approximately 4 hours to charge; the new iPad - possibly 7 hours.
Hmmm...

 

[randystand]

Shocked that people don't naturally put it on charge when they go to bed. I put it on charge from about 3/4% to 100% overnight and then it lasts me 2-3 days depending on usage.

Me too.

I guess some do not sleep

I thought the same thing. This is a non-issue. I don't care what happens between when I plug it in at night until the moment I wake up and go to work. As long as the device is fully charged I'm happy.

 

[0087215]

People do sleep, but on occasions it might happen that one needs to take his/her iPad with him/her while the battery is low. It sounds more convenient if you can charge it within 3-4 hours rather than 7 hours.

Insomnia is *lots* of fun.

What is the Amp output on the current iPad charger? I think I'm going to put together a slightly more powerful charger (I'm into r/c trucks so I know a thing or two about custom chargers and soldering). Also does anyone know what type of battery the iPad has, is it lithium polymer?

Yes, it is.
"Built-in 42.5-watt-hour rechargeable lithium-polymer battery"

According to the text written on it, 2.1A at 5.1V

Amazing what you can learn from the Tech Specs, eh?

You can easily achieve the same charge times as the iPad2 using more cells than bigger singular cells. I am sure Apple used more smaller cells, when spanning a charge across multiple cells the charge time remains the same versus trying to charge a single or 2 massive cells.

What ^ he ^ said!

I think you people are getting into a panic before you even get your hands on the new iPad! Lets see what Apple gives us before we hook the battery directly into the power grid! I am betting Apple got it right!

To be fair I was looking at the specs on the store page where you can compare them and it doesn't say the battery type

But that is good to know. I'm tempted to solder an Apple dock connector to some banana plugs and charge it on my r/c charger at 4A. Could also do 5A at 7.4v.

Let's indeed hope so. But you never know...

 

[Italianblend]

If they didn't mention it at the presentation, it hasn't been improved; expect larger charge times. You know they would've told us if it was a more efficient charger.

Might want to wait until you're sure Apple store have stock for replacements before you try this...

It will be interesting to see what the charge times are. With a 10 watt charger and a 42.5 watt hour battery, I'd guess you'd still see ~80% charge within four hours, then perhaps another three or four to top off. I'm NOT an expert by any means, just guessing. As I understand it, charging is not linear; if it takes five hours to achieve full charge, the majority of the charge is in the first chunk of that timeframe, with the top off taking a lot of the latter period.

Certainly if the charger remains the same 10W, the new iPad will need more time than the iPad2 if you're maxing out the charger.

Personally I'm not concerned; I've always just plugged it in before going to bed and found it fully charged when I woke up. So long as it will fully charge in that time, I'm good.

Won't matter since lithium ion batteries charging ability is controlled by the onboard control circuits. No matter how much current you feed the iPad (and any lithium ion battery) it will only allow charging at a controlled rate for safety reasons.

...The so-called miracle charger that promises to prolong battery life and methods that pump extra capacity into the cell do not exist here. Li-ion is a “clean” system and only takes what it can absorb. Anything extra causes stress....
