Several major UK retailers have announced pricing, and confirmed the release date.

Online retailer Clove UK is offering the SIM-free 16GB model of the Xperia Z Ultra for £599.99, including VAT. As the product page states, the retailer is currently taking pre-orders for the black and white models of the handset.

The Xperia Z Ultra is now up for pre-order at Handtec, which will sell the handset in all three colour variants: black, white and purple. Both white and black models carry a similar price tag of £611.99 (including VAT) whereas the purple variant is £12 cheaper, costing £599.99.

Amazon UK will also stock Sony's new large-screen smartphone. But Amazon UK customers will have to pay approximately £200 more than other retailers. The white edition of the Xperia Z Ultra is priced at £827.20 and the black model at £814.28. The price will no doubt drop significantly after launch.

Announced on 25 June, the waterproof and dust-resistant Xperia Z Ultra runs on a Snapdragon 800 chip, featuring a quad-core processor clocked at 2.2GHz. The device will ship with Android 4.2 Jelly Bean software.

It has an eight megapixel rear-camera with Exmor RS for mobile image sensor, which is claimed to be the first image sensor with HDR (High Dynamic Range) for videos and photos. The device has a two megapixel front camera.

The Xperia Z Ultra also features Battery Stamina Mode, Sony's unique battery management technology which improves standby time up to four times or more by closing the power-hungry apps when the screen is off and starting them up again when the screen is turned on. It is an NFC-enabled handset and supports 4G LTE network speeds.
