The difference between the iPhone 4 and the iPhone 4s

Apple’s latest iPhone is called the iPhone 4s and is the successor to the iPhone 4. It is interesting to see just how much these two phones do actually differ from one another.

Let us start by taking a look at the size. Both the iPhone 4 and the iPhone 4s are 11.5 cm tall, 5.9 cm wide and 0.93 cm deep and have a 3.5″ display. There is a small difference in the weight: the iPhone 4 weighs 137 grams and the iPhone 4s follow-up weights 140 grams – three grams more. They are very similar in appearance; both mobiles are available in black or white.

The biggest differences between the iPhone 4 and the iPhone 4s are in the camera, battery life, a new processor and a new operating system. The camera in the iPhone 4s has been improved. The 4s now has an 8-megapixel camera instead of the 5-megapixel variant found in the 4. This means that the follow-up has a camera with 60 % more pixels, and the pixels have been designed with a higher charge capacity than in the iPhone 4 camera, which means that the iPhone 4s camera can gather even more light, which in turn leads to higher resolution and more detailed photos. As well has having more megapixels, the iPhone 4s camera now has a specially developed lens with a larger f/2.4 aperture which lets in more light, so photos look brighter and colours are more precise and even thanks to the advanced hybrid filter, which shuts out harmful infrared light. The iPhone 4s camera also has an improved backlit sensor, advanced colour reproduction and reduced motion blur.

The battery life for the iPhone 4 permits a call time of up to 7 hours on the 3G network and up to 14 hours on the 2G network; while the iPhone 4s permits a call time of up to 8 hours on the 3G network and up to 14 hours on the 2G network.  The iPhone 4′s standby time is up to 300 hours, while the 4s has a standby time of up to 200 hours. Hence the 4s offers one hour more call time on the 3G network and one hour less standby time.

As most people know, the iPhone 4 uses Apple’s own A4 processor, which is powerful and energy-efficient, while the processor in the iPhone 4s has been upgraded to the A5 processor. The graphics with the A5 processor are up to seven times faster than the A4 processor, which means that games – for example – are more true to life and run more smoothly, and graphic-intensive apps work even better on the 4s. The operating system has also been upgraded to iOS 5 in the iPhone 4s.

To sum up, the differences between the iPhone 4 and its successor, the iPhone 4s are as follows: the camera, processor, battery life and operating system. The iPhone 4s should take better photos and be faster!
