Throughout the years, the iPhones have been succeeding one another with such speed and regularity that it has almost become a given that one will definitely follow every year. Smartphones do not seem like they will go out of fashion any time in the  near future and to ensure this, companies like Apple have made certain that the subsequent series and versions are made better and better every year.

The iPhone 4 and iPhone 4s are almost the same when looked at except for a few features that may standout prominently. The glass covers on the iPhone 4s for one are absent in the iPhone 4s but the thickness of the smartphones is pretty much the same. The iPhone 4S for example does not use the 5 megapixel camera like the iPhone 4 does. In its place is a multi-advantageous 8 mega pixel camera. Some of the advantages it has over the iPhone 4 camera include the fact that the images it produces are way sharper than those of its predecessor and it can work very well even without a flash.

The clear images can be attributed to the fact that it has a five element lens which gives it the advantage of wide aperture compared to what the iPhone 4 has.  Speed is a much needed element in any kind of communication device and iPhone 4s provides this without a doubt. It comes with a much faster speed of 5.8 mbps and 14.4 megabits per second for downloads. IPhone 4S is like the dream Smartphone that lets the user use it incessantly but never runs out of charge. With all the applications and special features that accompany it, one would imagine that the battery life of this device would be so bad and so short. Shockingly, the iPhone comes with 8 hours 3G talk time and ten hours of playback on video. This is so much time considering the fact that this is a device that is meant to multitask!

The Siri voice command software is perhaps the most exciting feature of all in the iPhone 4S. It is first and foremost unique to the iPhone 4S and it is like a personal assistant that never asks for any pay. It can actually talk back to the user and listen to commands and act. It is the most coveted advancement in the iPhone series of smartphones and all iPhone users rush for the iPhone 4S because of this special feature. For consumers who are new to the iPhone 4S, it might be a good idea to consult the how to user manuals for the device so that they can maximize on the functionality of this smartphone. It is amazing what it can do when the right commands are made.
