Oh Apple, you sneaky devil. Word on the street is that when Apple released the new iPad and dropped the price of the iPad 2, they upgraded the processor from a 45nm A5 to a 32nm A5. The result, noticeably better battery life on the new iPad 2 (iPad 2,4 below) compared to the original.
Interestingly, throughout a series of tests, the iPad 2,4 delivered better battery life than any other iPad model, including the recently released third-generation iPad. That Retina Display sure requires a lot of power!
One area in particular where the iPad 2,4 shines is in regards to video playback.
The iPad 2 holds a 19% advantage over the 3rd generation iPad (once again for obvious reasons), however the iPad 2,4 absolutely dominates with an 18% increase in battery life. At 15.7 hours this is an insane amount of battery life from a single charge. Granted end users will see lower numbers if you watch at higher brightness settings (200 nits on our test panel was around 40% brightness), but the advantage from the new iPad should still remain just as significant.
In any event, head on over to Anandtech where they have a boatload of information and test results that you’re likely to find pretty interesting.
