The Rare "iPad 2,4" Brings Improved Battery Life

clock May 5, 2012 00:25 by author Jeremy

With the New iPad out, the iPad 2 recently experienced a price-cut on its models, with the lowest 16GB WiFi iPad 2 available for $399. And therein lies the difference between models: their connectivity. The 1st type of iPad 2 is WiFi only (iPad 2,1), the second is WiFi and GSM (iPad 2,2), while the third is WiFi and CDMA (iPad 2,3). Which brings us to the topic at hand: the fourth-type, known as "iPad 2,4".

So what's the difference in connectivity? Like the 1st iteration, the iPad 2,4 is WiFi only. It's specialty, however, lies in the SoC (System on a Chip); in the iPad's case, it's more commonly known as the A5 chip, or the processor. Previous iPad 2's all had the same 45nm A5 SoC, while our new contender uses a 32nm A5 SoC.

How does this affect you? A 32nm processor is going to be more efficient overall than a 45nm processor. The end result is that owners will get (according to AnandTech) slightly better battery life.

The only downside is that there's no real way to tell outside of the box whether you're getting one of these new models. Once you open up the box, however, you can run a benchmark test or a battery test to see the specs of your iPad. So if you're going to purchase an iPad 2 sometime soon, start hoping you'll get the better end of this bargain.

iPad Battery Specs and Drop Tests

clock March 19, 2012 23:49 by author Jeremy

The latest iteration of Apple's tablet, the New iPad, is just as good at staying alive as its predecessors. Ever wonder how it manages to stay on for so long though? Especially in today's age, when battery-life is definitely a major factor in people's choices for laptops, smartphones, and other accessories.

Turns out, the New iPad has a whopping 42.5Whr battery. Quick flashback: the original 1st-generation iPad had a 24.8Whr battery, while the iPad 2 had a 25Whr battery. And while the New iPad is only 0.6mm thicker than the iPad 2, one just has to wonder: how in the world did Apple do that? According to arstechnica's teardown (note: Consumers should not try this at home), Apple simply managed to "more efficiently pack in the components - and increase the overall device thickness ever so slightly". No magic here, folks.

No matter how much you want to stare at the battery out of curiosity, tearing the device apart is always dangerous and likely shouldn't be done. And as fun as it is, professionally taking it apart is definitely still a better option than dropping it - which is proven to be fatalfor the iPad, if squaretrade's blog and video is any indication.
