We’ve compare the two to find out.
Note: This comparison will be updated periodically as we spend more time using and comparing each phone
iPhone 5S vs Nexus 5: Design
iPhone 5S – Aluminium rear, 7.6mm thick, non-removable back, 112g
Nexus 5 – Matt black plastic rear, 8.6mm, non-removable back, 130g
The construction of the Google Nexus 5 is one way the phone is able to sell for £300, instead of £500. It’s a matt plastic phone that doesn’t give you any access to the battery, and is formed of two parts rather than being a unibody device.
The iPhone 5S is made of more expensive stuff. It’s mostly a single piece of aluminium, apart from some glass inlays that help with wireless reception.
Both are phones that feel well-made and dense, but the iPhone 5S has the edge. The cool feel of aluminium, that iconic iPhone design and the slimmer body give it the victory here.
The iPhone 5S is almost unnervingly thin and light at 112g and 7.6mm. On its own, we’d also remark on the Nexus 5’s slim and light body – it’s 130g and 8.6mm thick – but side-by-side the iPhone is more impressive.
It’s also slightly easier to handle thanks to its significantly narrower body. There’s a clear reason why – the iPhone 5S’s screen is a whole inch smaller. The Nexus 5 is 69.2mm wide, the iPhone 5S 58.6mm. With almost a centimetre difference, the iPhone is much friendlier for small hands.
That said, LG (maker of the Nexus 5) has put a lot of effort into making the phone as narrow as possible by reducing the screen bezel.

iPhone 5S vs Nexus 5 – Screen
iPhone 5S – 4-inch 1,136 x 640 pixel IPS screen
Nexus 5 – 5-inch 1,920 x 1,080 pixel IPS screen
With a full inch difference between the screens of the Nexus 5 and iPhone 5S, there are clear benefits to going Android here. For movies, the Nexus 5 is clearly superior. The extra screen space makes for much more comfortable and rewarding viewing.
Discounting that the iPhone 5S has a much better games library, the screen is also better for gaming. A big, bright 5-inch display is much more immersive than the iPhone 5S’s 4-inch one.
Looking in a more abstract sense, the Nexus 5 and iPhone 5S screens are fairly even. They both have pixels tightly packed enough to make images and text appear super-sharp, and hide that the screen is made up of pixels at all.
They both also use the same screen type – IPS. This is a kind of LCD screen designed for solid angled viewing – and both displays provide good colour and contrast, and black depth.

iPhone 5S vs Nexus 5 – Software
iPhone 5S – iOS 7. 1
Nexus 5 – Android 4.4
A much more important question than which hardware to go for is the ecosystem to pick – Android or iOS. Both phones run the very latest version of their respective systems – iOS 7 and Android 4.4 KitKat.
These days, both are very fast and look good – before iOS 7 the Apple mobile OS was starting to look a little musty.
The main benefit of iOS is that it offers the best apps and games selection. You just can’t beat the App Store.
With Android, you get much more control. You can change keyboards, tweak the look of the system a whole lot more and can generally connect to other devices much more easily – whether a TV or just your computer.
We could go on, but the debate around iOS vs Android is long enough, complicated enough and emotive enough to fill several volumes.
iPhone 5S vs Nexus 5 – CPU, RAM, GPU
iPhone 5S – Apple A7 64-bit CPU dual-core 1.3GHz, 1GB RAM, PowerVR G6430 GPU
Nexus 5 – Snapdragon 800 quad-core 2.3GHz, Adreno 330 GPU
Look at the numbers and the Nexus 5 sounds much more powerful than the iPhone 5S. It has a quad-core 2.3GHz processor with 2GB of RAM, the iPhone 5S a dual-core 1.3GHz chip with 1GB of RAM.
Many will assume the iPhone 5S is weaker, but it is actually the more powerful of the two.
The iPhone 5S is the first 64-bit phone in the world, and it’s a seriously powerful device that offers desktop-like functionality in some of the apps optimised for it. For example, in audio sequencer Garageband you can use 32 tracks instead of 16 in the non-64-bit phones (granted, full sequencers offer ‘unlimited’ tracks these days.)
In the Rightware Basemark test, which compiles scores from a number of gaming benchmarks, the iPhone 5S comes out with 15.54 points, against the Nexus 5’s 14.27 points. It’s an abstract score, but tells you that the iPhone has more 3D gaming power.
In real world use they're both supremely fast phones, and the Nexus 5 is outstanding considering the price, but in totally unemotional, hard numbers the iPhone 5S comes out on top.
iPhone 5S vs Nexus 5 – Camera
iPhone 5S – 8-megapixel main 1/3 inch sensor, dual-LED flash, f/2.2 aperture
Nexus 5 – 8-megapixel main 1/3.2 inch sensor, single-LED flash, f/2.4 aperture, OIS
Both these phones have 8-megapixel cameras, a megapixel count that sounds a little low when the Samsung Galaxy S4 has a 13-megapixel camera and the Xperia Z1 a 20.7-megapixel camera. However, each has a few minor tricks up its sleeve.
The iPhone 5S has a slightly larger-than-average sensor. It is 1/3 of an inch rather than 1/3.2 inches – the standard size, and that of the Nexus 5. Larger sensors result in less noisy pictures, given the same level of processing.
The Nexus 5 also has a slower lens than the iPhone 5S – f/2.4 to the iPhone’s f/2.2. A faster lens again results in less noisy pictures, and better low-light performance.
However, the Nexus 5 has one thing the iPhone 5S does not – optical image stabilisation. This buffers the lens to compensate for any movement made while you’re taking photos, and will reduce the number of blurry photos you take.
We’ll update this comparison once we’ve had a chance to compare them properly.
Given the Nexus 5 costs just over half the price of the iPhone 5S, it’s a real bargain. It offers comparable (although slightly less) power and a larger, similar-quality screen. There are benefits with an iPhone – the Touch ID sensor is great, the build quality is a bit more impressive and the app selection is better – but if you want the most phone for the least cash, the Nexus 5 is the way to go.
