The IPhone 4 – Information & Advice
Apple has usually been able to run alone when setting the standard in the world of smartphones. In recent years, however, other companies have caught up with their own research and development of handsets and put some pressure on Apple. The iPhone, Apple’s bread and butter, continually receives updates to keep the company ahead, and it has been released as the iPhone 4 to an eager public.
One of the changes found in the iPhone 4 is on the inside of the phone. The iPhone 4’s predecessor, the 3GS contained a Samsung-based Cortex CPU. This has been replaced by Apple’s own A4 chip, the same one used by the iPad. The iPhone 4 does not quite speed along at the same rate as the 1GHz available to the iPad, but it is still more than fast enough. It brings up graphics quickly and navigates seamlessly. Those who find it too slow are likely looking for something to complain 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.
It almost wouldn’t be worth having the Retina Display if the iPhone 4 possessed the 3 megapixel camera of past models. There are no worries here, because it doesn’t. The iPhone 4 has upgraded to a 5 megapixel camera that includes a backside-illuminated sensor with improved sensitivity to light. Also featured is an LED flash, although it can blow out some photos, a symptom not uncommon in flashes of this kind. It really is not that big of a deal, because the camera takes great pictures in low light and without a flash.
Finally, Apple has decided that it is time to produce a phone that allows multitasking. Though not backgrounding in the strictest sense of the word, the iPhone lets some APIs that imitate backgrounding to run simultaneously. Critics will cry foul, but for regular, everyday users, it is just fine. Until now, Apple has stated that their smartphones would suffer battery drain by performing multitasking. The iPhone 4 has cleared up any potential issue here, as it has been known to produce almost 40 hours of normal use in some tests.
The iPhone 4 has placed Apple at the forefront of smartphone technology once again. Featuring a Retina Display unmatched in the industry and improved performance over older models, Apple’s iPhone 4 is a standard setter. Customers will be thankful for the efforts.
