Nexus 5 and Iphone 5S are two of the most highly-anticipated flagship handsets of the year are now out in the wild at long last. We take a look at how the Nexus 5, Google's LG-made Android 4.4 KitKat phone, compares to Apple's iPhone 5S.

The Display

Apple continues to stick to its guns on the idea that a smaller 4-inch display is more manageable while the 361 pixel-per-inch (ppi) Retina panel is perfectly optimised for the maximum sharpness your eye can perceive at typical smartphone viewing distances.

Whether you agree with that or not, it’s definitely an impressively sharp, colourful and bright IPS+ LCD display.

But then, so is the Nexus 5’s larger 4.95-inch IPS+ LCD display with a full HD 1920x1080 pixel resolution at 445ppi.

There’s not much between these two on picture quality but the Nexus 5 has almost a full inch on the iPhone 5S and for some that may understandably just seal the deal - more real estate for viewing games, webpages and films is a definite plus and the larger proportions hardly make it an unweildy device, despite what Apple may think about thumb-reach.

Connectivity and Battery

Both handsets have a pretty standard set of connectivity options, including wide-ranging 4G and 3G mobile data, Wi-Fi and Bluetooth 4.0. Apple’s iPhone 5S uses the company’s Lightning connector and doesn’t use NFC in favour of iBeacons, while the Nexus 5 has NFC and microUSB.

The iPhone 5S features a 1,560mAh battery pack compared to the Nexus 5’s 2,300mAh unit. Neither setup is removable.

The Operating System

There isn’t a “best” option here as both Android 4.4 KitKat and iOS 7 offer a similar set of functionality from drop-down notifications menus to a quick settings interface and multitasking carousel. Of course both look very different and Google’s system is a little more open. Each also has access to a massive range of apps, games and content, as well as music and video streaming services.
