New iPad takes “several hours” to charge due to bigger battery

By , Mar 15, 2012

For those of you wondering how Apple managed to keep the iPad’s legendary 10 hour battery life despite the addition of a Retina display and LTE technology, we’ve come across a good explanation: the battery is a lot bigger than its predecessors. Surprise!

How much is a lot? Well according to the recent iFixit teardown, and other reports, the new iPad’s battery has roughly 70% more capacity than the one used to power the iPad 2. But unfortunately this also means that it takes a lot longer to charge…

MG Siegler explains this phenomenon in his review of the new iPad:

“It appears they’ve had a fairly major breakthrough in their battery technology. While the new battery clearly isn’t much bigger than the old one, it can hold much more juice (42 watt-hours versus 25-watt-hours). The downside of this is that I’ve found it takes quite a bit longer to charge the new iPad. As in several hours — you’ll probably want to do it overnight.”

If you haven’t guessed by now, none of this is really all that surprising considering what Apple has pulled off here. While LTE has been the blame for poor battery life in several devices over the past year, the new iPad is still good for nearly 10 hours of continuous usage. And that feat becomes even more impressive when you mix in the Retina display and quad core graphics processor.

Our iPads should be arriving tomorrow so make sure you check back with us this weekend for our hands-on impressions.

What do you think? Is the iPad’s battery life worth the extra charging time?

      Haha I always thought about that!! But the electronics inside run off a certain voltages.

    Hmm. If LTE is the biggest culprit when it comes to battery drainage, wouldn’t make sense to make the non-LTE (Wifi-only) iPads thinner with smaller batteries and in turn wouldn’t take too long to charge?

      Your looking at it wrong – If you don’t have the LTE model then you should get well over 10 hours – that has to be a bonus. Battery (and storage) is king for mobile devices

    Me likes the idea of a Retro-Fit Kit to install iPad 3 Battery into iPad 2.

    It would be fairly easy to Apple fix it:
    Use a higher wattage for the power AC brick of the new iPad (e.g.: 20W).

    But it looks like that the old 10W adapter is still provide in the new iPad….

    Don’t come to say that it would make the 10W brick useless, because it could still be used, although not recommended.

    Ooops…Apple hadn’t saw this “flaw”? Or is now the Mighty Apple surrendering to the old politics of using as much as common components as possible, even if this is not the best solution?

    Where is the famous frase that all Apple high executives says: “We just try to make the best product”?

    I wonder what theyll come up with for the “new iPhone” this year. If it has LTE & HOPEFULLY a higher resolution display..we can’t just stick a bigger battery in it Lol. Hope they come up with a solution..

    • KewlDewd

      Why on earth do you need a higher resolution iPhone display? The current retina display is already more pixel dense than the new iPad. You flat out don’t need more pixels at that size.

        Your right. My apologies. Been a long day..but either way..LTE will drain the hell out of the battery. If some people think they have battery issues now, I can only imagine whatll happen then

      according to the article, it’s not a bigger battery. physically, it’s the same size, just higher capacity.

        Now I understand..thanks for clearing that up

    WE NEED TO KNOW IF THE WI FI ONLY MODEL RUNS LONGER WITHOUT LTE!!!!!!
    If so that would be revolutionary! It’s got to be the least 5 more hrs that the LTE versions! IDB LETS US KNOW

    Can i put ipad3 battery into ipad 2…it would be legen w8 fr it……..dary…;D

    Dang, this title is misleading, it doesn’t take several hours, it takes the freaking whole night! I’ve been charging it since about…. 9 or 10pm with 10%-15%, it’ve been 6 hours to get to 89%

  • http://twitter.com/Sarida58 Barbara

    The battery life is fantastic I watched videos most of the day yesterday, didn’t charge it during the night, and still had 21 percent left.

    I’ve been charging it for four hours today while playing videos (Netflix) and it is only up to 59%.

    So I will be doing nighttime charging from now on.

    Is it worth it? Uhm…YES! I upgraded from the 1st gen, and you bet. That’s why I’ve been watching Netflix on it instead of my 37″ LCD television.

    But yeah…don’t I wish my iPhone 4 had a battery that would last 24 hours with minimal use!
