Difference Between iPhone 4 and iPhone 4S

iPhone 4 VS iPhone 4S

The release of the next iPhone model is a much anticipated yearly event. The release of the iPhone 4S disappointed a lot of people who were expecting the iPhone 5 because the iPhone 4S looked pretty much identical to the iPhone 4. But the iPhone 4S offers significant upgrades to differentiate it from its predecessor. The biggest difference between the iPhone 4 and the iPhone 4S is the latter’s use of a dual-core processor with an improved chipset. The iPhone 4S is the first of the iOS devices to sport a dual-core processor, giving it a processing edge and a smoother experience.

Another major difference between the iPhone 4 and the iPhone 4S is in their cellular radios. The
iPhone 4 came in either GSM or CDMA models which are not compatible with each other and can only be used with their respective networks. On the other hand, the iPhone 4S has both radios and is considered to be a world phone since you can use it just about anywhere in the world with cellular coverage.

Also quite notable is Siri, Apple’s speech recognition software that is only available on the iPhone 4S. Siri can directly answer spoken questions of the user by giving a direct answer or providing search results when it cannot provide a direct answer. Siri is quite entertaining and is one of the main reasons for those who upgraded from the iPhone 4 to the iPhone 4S.

The iPhone 4S also ups the camera resolution from 5 megapixels on the iPhone 4 to 8 megapixels. With all other things held constant, a higher resolution camera would always yield a better picture. The iPhone 4S is also capable of recording 1080p video, a significant improvement to the 720p resolution of the iPhone 4. The camera sensor of the iPhone 4 is capable of recording 1080p videos, but it is the processor that cannot cope with the high processing cost. The dual-core processor of the iPhone 4S and not the higher-resolution camera enables it to record at the higher resolution.
