So they can look the same there are some significant differences between the 4 and 4S and it is these differences between the processor and the control system of the camera that is the Apple iPhone 4S fastest and most powerful phone intelligent to date.
Design
As already mentioned by the factor of iPhone 4S same shape and construction materials than its predecessor. The two bars are identical to a subtle change, the antenna system. The new design incorporates two separate antennas, each transmitting and receiving data, which makes the calls for better call quality and provide a faster 3G connection. Although we can not ignore sound improvements have certainly seen improvements in data services, representing the pages faster and download speeds while surfing the web. The evidence of this change is in the form of two additional bands at the top of the phone.
In addition to aesthetics are almost identical, there is 3.5 inch (960 x 640pixel) Retina display makes the volume rockers, Audio On / Off button and data ports.
Supply and operating system
The Apple iPhone includes 4S A5 dual-core processor clocked at 1 GHz, which is found in the iPad 2, and a dual-core GPU. According to Apple, the iPhone 4S can match twice as fast as 4, with a performance of seven times faster graphics. This increase is not the same as the iOS Apple is not a system you could ever call slow, however, to operate the software slightly - to quickly switch between applications, the cost of resource intensive programs as you read the media and you will be pleasantly surprised by the speed at which open and smooth transitions.
Battery life is good to remember, although the inclusion of the A5 iPhone 4S chipset is said to be able to send up to 8 hours talk time and 3G and 40 hours of music playback. This will no doubt please many current iPhone users who are looking to improve, because it is one of the few areas that the company seems to miss the past.
iOS 5 is the next in line to approach and brings a host of improvements. Finally, users will be able to perform updates over the air sync and iTunes. Review options are now also fully customizable, and there is a pull down bar to accommodate all the new releases, similar to that found on Android devices. The software will be pushed out of four iPhone, iPod Touch, iPad, and iPad 2 in the coming weeks to learn more about iOS 5, and the improvements it brings, you can read all this in our full iOS 5 Summary .
icloud is another great improvement, and marks a change in the way users access and store information. This is a free service that allows users to download multimedia files, contacts, calendar entries and system settings from their combined "cloud", they can then access. Additional security features have been added to incorporate external monitoring, blocking and wiping services previously offered by MobileMe. This is a free service and Apple, even giving away 5 GB of storage space for all users, more storage space is available if needed, but you'll pay for it.
The feature that really distinguishes 4S iPhone iOS 5 and apart from the rest of the pack, however, is the voice assistant, Siri. While the voice recognition software has been around for some time, Apple has really raised the bar with Siri. The software is designed to follow a natural speech, whether an order or a question. For example Siri can provide answers to simple questions like "What is the weather in Stoke on Trent? And also book meeting requests and to help organize your schedule. Where it gets interesting is how it recognizes not only the words but the context and meaning behind them, for example, you could say "tell Mr. Smith, I'll be ten minutes late for my appointment'et Siri will open the screen and send an SMS saying that Mr. Smith late. Not only that, but the message was read Siri contact you to confirm and wait for your voice to the request "send" before shooting.
Camera
The camera was a considerable upgrade, it now has 8 megapixels instead of 5, and they also increased the size of the opening to let in more light. There is a new front lens elements 5 and the back lighting was completed ahead of time to capture more light in each pixel. The result of these improvements are images that are sharper color and better than before. The video has received an upgrade as well, he is now in 1080p HD and has face recognition technology and video stabilization.
Other technical characteristics:
• 16 GB, 32 GB or 64 GB of memory
• Wi-Fi
• Bluetooth 4.0
• Assisted GPS
• Three axis of rotation
• Accelerometer
The disadvantages?
Of course, the fact that it shares the same chassis as the iPhone 4 will push a few feathers. But if Apple decides to stick with the users tend to get a design overhaul in the next iteration. To be honest, it would not put us off buying one because there are many improvements in the shell to hide aesthetics, and it's not as if it were an ugly phone either.
Conclusion
The iPhone 4S is a big step forward on the iPhone 4, bringing the device online with the recent series of competitors. iOS improvements will no doubt attract new fans to the platform and the assistant Siri voice is a big plus. It would have been nice to have seen Apple designers get creative with the body and may even increase the size of the screen, but now we are more than satisfied with what we have.
