The Apple iPhone 4S is finally
official. Though not dramatically different from the iPhone 4, the 4S features a
faster processor, better graphics performance, and other improvements.

Review:As expected, Apple
introduced the iPhone 4S at its “Let’s Talk iPhone” event on October
4. The news was underwhelming and disappointing to many who were also expecting an iPhone
5. There’s also the fact that the iPhone 4S looks almost identical to the iPhone
4. However, there’s more than meets the eye, as Apple made a number of changes
under the hood to improve on performance, including a faster processor, a more
advanced camera, and a new antenna design. In addition, Apple expanded its
family to include Sprint and a 64GB model.

 

Processor and battery life
The iPhone 4S features Apple’s A5
dual-core 1GHz processor along with a dual-core GPU. Apple says the new chipset
will make the iPhone 4S twice as fast and offer graphics performance that is
seven times faster than the iPhone 4’s. Despite the more powerful processor, the
company claims the smartphone will be able to provide 8 hours of talk time over
3G, 14 hours over 2G, 6 hours of browsing over 3G, 9 hours via Wi-Fi, 10 hours
of video playback, and 40 hours of music playback.
