Sony's new flagship Android smartphone is the Xperia Z, with a 5in Full HD screen. Here's our Sony Xperia Z video review.

Sony Xperia Z: Design and build quality

Overall the Xperia Z has a distinctly premium and desirable nature. Build quality is excellent and the attention to detail exemplary.

Sony Xperia Z: Hardware and performance

The Xperia Z has powerful core specifications: a quad-core processor and 2GB of RAM yielded a good result in the Geekbench 2 test of 1986, only just short of the Nexus 4's record of 2009.

The Xperia Z also managed a very impressive 30fps in the GLBenchmark graphics test, too.

Like the Nexus 4, the Sony didn't do so well in the SunSpider JavaScript test with an average time of 1791ms, although we found surfing the web on the pre-installed Chrome browser smooth and responsive.

The 5in Reality display with its Full HD 1920 by 1080 resolution really makes the Xperia Z stand out. The screen is stunning and easily the best we've ever seen on a smartphone.

Content looks incredibly sharp thanks to its whopping 441ppi pixel density. Colours look particularly rich and vibrant. It really is like holding a TV in your hand.

The Xperia Z is a bit limited on the storage front, with only a 16GB model. There is a microSD card slot for adding more storage, though.

There's Wi-Fi, Bluetooth 4, NFC, aGPS and DLNA. Beyond the usual microUSB and headphone ports, there are two metal contacts on the left hand side of the handset for use with a docking station, and you get support for wireless charging and 4G.

Sony Xperia Z: Cameras

The Xperia Z has a 13 Megapixel rear facing camera with Sony's Exmor RS sensor. We're very impressed with the camera software and the resulting photos and video.

The Z is the first smartphone to enable HDR in video mode. There's also a decent 2 megapixel front-facing camera.

Sony Xperia Z: Software

The Xperia Z comes pre-loaded with Android 4.1.2 Jelly Bean and will be upgrade to version 4.2 shortly after launch according to Sony.

Sony Xperia Z: Battery life

In use the Xperia Z not only lasted a day but went a good way through a second. We went 31 hours and still had 20 percent of the battery remaining. We achieved this with moderate usage and the Stamina Mode switched on.

Sony Xperia Z: Verdict

The Xperia Z is the first smartphone which Sony has really nailed. We love the stylish, desirable and rugged design. The combination of excellent performance, a stunning screen and great cameras make the Xperia Z a force to be reckoned with.
