Nexus 4 vs Lumia 920: build and design
The Lumia 920 is the biggest Windows Phone we've seen. We measured it at 12 millimetres at its thickest point and it has a relatively brick-like weight of 185g.
The 920 feels unwieldy, strong, and a little plastic to the touch, but its one-piece polycarbonate body sits neatly flush to the Corning Gorilla Glass front.
The uni-body design means there's no removable rear cover - and therefore no access to the battery. The only moving part is the top loading micro-SIM card tray which feels distinctly cheap and plastic. The three side-mounted buttons have a smooth action.
The Nexus 4 feels great in the hand, a true premium smartphone. There's a silver bezel around the screen and, if you flip the phone over, you'll find unique finish consisting of a matrix of tiny silver dots, each reflect light at different angles. It's a love it or hate it finish. Group test: what's the best Android phone?
We were initially a bit worried about the glossy finish of the Nexus 4, making it quite a slippery handset. However, between the front and back of the phone is a grippy rubbery finish. There's no removable cover and the phone feels sturdy and well-built.
Nexus 4 vs Lumia 920: performance
Inside the Nexus 4 is a Qualcomm Snapdragon S4 Pro, a quad-core chip clocked at a healthy 1.5GHz and 2GB of RAM. It set a new record for a phone of 2009 points in the GeekBench 2 test. It also matched the iPhone 5 in terms of graphics with 39fps in GLBenchmark.
Navigation around the system happens without lag although menus and lists tend to judder somewhat if you scroll slowly. Only a select few apps such as Nokia Maps and Cinemagraph take a few seconds to load.
Nexus 4 vs Lumia 920: display
We were impressed with the Lumia 920's PureView HD+ display with its 768 by 1280 pixels. This gives the Lumia 920 an impressive pixel density of 332 pixels per inch so everything looks pin sharp.
The screen boasts excellent contrast and eye-popping colours. The touchscreen is very responsive, so much so that you can sometimes use it with non-smartphone gloves.
The 4.7in IPS screen looks stunning with a detailed 768x1280 resolution, excellent contrast and rich colours. We found it performed particularly well outdoors.
Nexus 4 vs Lumia 920: camera
We found still photos from the 8.7Mp PureView rear facing camera with its Carl Zeiss lens very good. Colour balance, saturation and exposure were all of a good standard but some photos weren't quite as sharp as we'd hoped. We also found a lot of noise reduction leading to a loss of detail.
The most outstanding feature of the 920's camera is its optical image stabilisation. It's the first smartphone to have a floating lens which means video footage, which can be recorded in full-HD, is extremely smooth.
The Nexus 4's 8Mp rear and 1.3Mp front facing cameras provided us with decent results. The easy to use camera app includes an HDR mode and Photo Sphere for 360 degree panoramas.
Nexus 4 vs Lumia 920: storage
Storage is the Nexus 4's biggest downfall with only 8GB and 16GB models to choose from and no microSD card slot.
The 920 has 32GB of built-in storage, but no memory card slot for expansion. Cloud storage can be accessed via the pre-loaded SkyDrive app.
Nexus 4 vs Lumia 920: connectivity
The Lumia 920's physical ports consist of a headphone jack and microUSB port, and there is Wi-Fi and Bluetooth. The 920 has an NFC chip and DLNA certification. Most exciting of all is Qi wireless charging.
Connectivity on the Nexus 4 includes dual-band Wi-Fi, Bluetooth 4.0 and NFC. However, there's no support for 4G in the UK.
Nexus 4 vs Lumia 920: software
The Lumia 920 runs Microsoft's new mobile operating system – Windows Phone 8. It's a great-looking OS, although there aren't many apps for it just yet.
The Nexus 4 comes with the latest version of Android, 4.2 Jelly Bean. This incremental update brings a few new features such as widgets on the lock screen, quick settings, additional cards in Google Now and Daydream. The best improvement and our favourite is gesture typing on the keyboard.
Nexus 4 vs lumia 920: battery life
We got comfortably through a day using the Nexus 4 with enough battery life left over for the next day. Wireless charging is a convenient way to keep the phone topped up.
Nexus 4 vs Lumia 920: verdict
The Nexus 4 is a top-end smartphone for a bargain price. The Lumia 920 is much more expensive but offers similar performance with much greater storage and a better camera. The choice ultimately comes down to a subjective decision between Android and Windows. Either way, you are unlikely to be disappointed.
