Introduction to the iPhone 4S – A5 Processor, Siri and 8 Megapixel Camera

As was to be expected, Apple indeed did lauch the iPhone 4S instead of an iPhone 5. The iPhone 4S is exactly the same as the iPhone 4, but is faster and contains more memory. The 4S also comes with the iOS5 assistant, a program that listens to your voice and answers your questions. So if you would ask “I am looking for a Chinese restaurant in Amsterdam”, the assistant will interpret your question and provide you with a list of addresses. The 4S also has a new camera.

We all hoped that Apple will come up with iPhone 5 but all we got is slightly improved version of iPhone 4 which is not called iPhone 4S. Apple haven’t said what “S” stands for in the name but it’s either “Speed” or “Siri”, because these are the two things that makes it different from its predecessor. If we can trust Apple then iPhone 4S is nearly two times more powerful than its predecessor. Another improvement is its 8-megapixel camera now capable of recording up to 1080p video.

The iPhone 4S has a dual-core A5 CPU and dual-core graphics for a faster and more detailed 3D representation. According to Apple, this hardware is seven times faster than the iPhone 4 when playing games, and two times faster during normal use.

The iPhone 4S makes use of faster HSPA+ networks, so downloading can be speed up until 14,4 Mbps.

The new camera contains 8 mega pixels, which is a great advantage in relation to the iPhone 4. The camera also contains a CMOS backside illuminated sensor, which provides 73% more light than with the regular iPhone 4 sensor. The camera system as a whole is also faster.

The iPhone 4S als has new HD video thanks to a new type of sensor. Video can be watched with 1080 p and has real-time image stabilization. It also dampens the sounds from the surroundings.

According to Apple, the new processor has to negative consequences for the duration of the battery. 3G will provide 8 hours of battery duration. 2G will provide you with 14 hours of speaking time. 3G web browsing will leave 6 hours of battery time. When using Wi-Fi the battery will last 9 hours.

The iPhone 4S has 16, 32, or 64 GB memory.

Siri – the smart voice assistant of the iPhone 4S

Apple also introduces the smart assistant of the iPhone 4S: Siri. This assistant will only work on the 4S due to the A5 processor. Siri can call people, play music and receive e-mails and text messages. A human voice is available to read the messages aloud. Siri works by means of voice recognition. This is not the most prominent feature of Siri, according to Apple. The program really understands the language and can do hard tasks. Siri also answers your questions. You can speak with your own assistant.


It can be concluded that it is a great phone with a lot of possibilities. Especially the assistant is a great app that can help you finding your way around and help remembering appointments and other things. The technology has been extended greatly and delivers all possibilities.

The iPhone 4S have faced several logical improvements such as redesigned antenna, better camera and processor which will allow to compete against its main rivals for at least one more year until iPhone 5 will be released.
