Learn About The iPhone 4
A few short years ago, Apple sat on top of the smartphone world relatively unchallenged. As time has passed, other manufacturers have pumped money into their own development programs and closed the gap considerably between Apple’s flagship iPhone and their own handsets. In an attempt to stand head and shoulders above the competition once more, Apple has unleashed the iPhone 4.
The iPhone 4 features some changes on the inside from previous models. Replacing the Samsung-based Cortex CPU in the 3GS, iPhone 4’s predecessor, is Apple’s own A4 chip. Those in the know will recognize this as the same chip found in the iPad. While the iPad boasts 1GHz of speed with the A4 processor, the iPhone 4 doesn’t quite reach those heights. This is not to say the phone is slow by any means. It renders graphics quickly and navigates smoothly. Users who are looking for a high performance phone have nothing to worry about.
Those quickly-rendered graphics are displayed on a 3.5 inch screen with 960 x 640 pixel resolution. Combine that with a mind-numbing 326 ppi pixel density and you have a display that is absolutely second to none. The incredible resolution makes up for any shortcomings in size, and it has even earned the name of Retina Display. It is so named due to the claim that it presents graphics in more detail than the human eye is able to distinguish. It may seem like overkill to present clarity that the user can’t see anyway, but at least consumers need not worry about a less than stellar display. In fact, many testes of the iPhone 4 have stated that the Retina Display easily provides the sharpest images they’ve yet seen.
With a display so sharp, one would hope that Apple has improved on the rather weak 3 megapixel camera found on older models. They have, as the iPhone 4 features a 5 megapixel camera with a backside-illuminated sensor that is more light-sensitive. The LED flash is one of the smaller sizes and can blow out some photos, but the iPhone takes terrific photos in low light and without a flash.
Multitasking finally makes an appearance on an Apple smartphone with the iPhone 4. Technically, the phone doesn’t offer true backgrounding, but it does allow a few APIs to operate at the same time that imitate backgrounding. For those who are looking for typical use, it presents no problem at all. Apple claimed that their reluctance to embrace multitasking abilities was due to the battery strain it would put on the phone. iPhone 4 users will not find battery life a problem at all, as some tests have produced nearly 40 hours of regular use on one charge.
With the iPhone 4, Apple has once again established itself as a leader in smartphone technology. With a Retina Display that none other can boast and improved performance, they have set the bar high. Not only has Apple won again, so have their customers.
