iPhone 5 vs iPhone 4S: What Improvements To Expect

By  | 

The iPhone 4S has been massive, but it’s becoming overshadowed by the iPhone 5 and its rumored specs, so we’re going to have a side-by-side comparison. Remember, though, that we’re using leaks about the iPhone 5, and we’ll do a new review as soon as we know hard facts.

If you’re after a definite comparison, you’ll have to wait until the official launch – this is expected to be on September 12.

iPhone 5 vs iPhone 4S (rumors)


The iPhone hasn’t changed in size by very much. The first iPhone measured 115x61x11.6mm and weighed 135g. Apple’s iPhone 4S measures 115.2×58.66×9.3 and weighs 140g.

Despite the other changes, the iPhone has kept the same 3.5” screen, so that all the built-in iPhone software and apps will run smoothly across all versions. This makes us think that the iPhone 5 will also have a 3.5” screen to maintain continuity.

Having said that, there are signs that Tim Cook isn’t scared of changing the dimensions of flagship products – we’ll soon have a 7” iPad, apparently.

Despite what we think, rumors all suggest that the iPhone 5 will try to keep up with its Android rivals by upping its screen size. The only nay-sayer to these rumors is the lack of agreement on the new screen dimensions. Leaks range from 4-5”.

The most credible estimates are a 4” screen, from leaked display photos. Whatever the size, though the new iPhone 5 screen will almost certainly be Retina.


The iPhone 4S has a dual-core Apple A5 processor, which doubled (in theory) the iPhone’s processing capacity from the single-core chip in the iPhone 4.

PC Advisor, looking at previous chips used by Apple, reckons that the iPhone 5 may have an A6 processor that may even be quad-core, doubling the processing capacity again. Apple could opt for the A5X chip – dual-core with quad-core graphics – used in the new iPad.

Just to note – dual-core chips don’t give twice the power of single-core chips, but they can do twice as many processes at once, which makes multi-tasking faster.


The cameraphone competition has cooled down somewhat. Once upon a time phone makers would pack as many megapixels as they could into their cameras. Now it’s all about the quality.

The iPhone 4S’ 8MP rear camera has always been well-regarded, though both for photos and videos. This might push the need to improve the cameras down Apple’s to-do list.

One interesting rumor is that the iPhone 5 will “have a multi-point camera focusing system”. What? This rumor is on the back of Apple winning a patent for a multi-point focusing system. According to the website that hailed this news, the patent “describes a system that lets the user of a camera-equipped device select two or more areas of focus on a touchscreen which, when a picture is taken, are passed through a dedicated image processor to produce optimal sharpness and exposure for both regions.”

Other rumored additions to the iPhone 5 which the iPhone 4S never had was 4G LTE connectivity and NFC capability. This is all just speculation, and so we can’t give a definitive verdict yet. One thing is for certain, though, the iPhone 5 will be a huge improvement and it has to be given that the iPhone 4 to 4S jump was seen as a minimal upgrade like the 3G to 3GS was.
