A seven minute video gives us the closest and most detailed look yet at the upcoming Google Nexus 5 smartphone.

Heavily leaked for the past few weeks and expected to be annoouned this week, the Nexus 5 is a smartphone manufactured by LG, has a 5in, full HD screen and a simple design that is very similar to last year's Nexus 4.

Uploaded to YouTube on 12 October, the video shows what is believed to be a prototype of the Nexus 5, as the phone is missing the 'Nexus' name written across the rear case - as shown in other leaks claiming to be the new phone.

Otherwise, the device shown here lines up closely to what we're expecting of the Nexus 5, and what previous leaks have shown. Gone is the unique, glittery rear of the Nexus 4, replaced by plain black plastic with a rubberised finish. The back also houses an 8 megapixel camera with the same oversize chrome ring around the lens, as also featured on the 2013 Nexus 7 tablet.

The phone appears to be running a beta version of Android, referred to as KeyLimePie in the phone's About page. Google was expected to called the next version of its popular op[erating system Key Lime Pie, but following a tie-up with Nestle, announced in August that Android 4.4 would be known as KitKat.

It is unclear if there are any differences between Key Lime Pie (which was what Google called the software internally) and the final version which will be called KitKat.

Specs

Last month a leaked manual for the Nexus 5 claimed the new phone will have a 5in screen with a resolution of 1920 x 1080 giving it a pixel density of 442 pixels per inch; the phone is powered by a 2.3GHz Snapdragon 800 processor with 2GB of RAM, and there will be 16GB of storage in the cheapest model.

The Nexus 5 will also include wireless charging, a feature adopted by Nokia last year, but soon relegated to a range of attachable cases instead of being built into the phones themselves. Wireless charging has failed to catch on in the smartphone world, so it will be interesting to see if its inclusion by Google and LG in the Nexus 5 will be enough for other manufacturers to give the technology another go.

Improving on last year's model, the Nexus 5 will come with 4G. The Nexus 4's lack of superfast mobile internet wasn't a problem last year, as the UK had just one 4G network up and running, but with all three major networks now having 4G up-and-running, the inclusion of 4G on the Nexus 5 will be key for its success.

Although rumours suggest a 14 or 15 October launch - and the sheer volume of leaks mean the phone must be close - Google is yet to send out media invitations for a launch event, which usually happens a week in advance. Safe to say, however, that the Nexus 5 will be on sale in time for the Christmas rush.

Price

As for price, this was always the Nexus 4's party piece, offering industry-leading hardware and software at half the price of its Apple and Samsung rivals. We're yet to hear how much the Nexus 5 will cost in the UK, but information recently leaked to PhonesArena claims US prices of $299 (£187) for the 16GB model, SIM-free, and $399 (£249) for a 32GB version. Interestingly, this report also claims the more expensive model will get a larger battery, at 3000mAh compared to the cheaper phone's 2300mAh capacity.

Estimating UK prices from this information isn't easy, but we still expect the Nexus 5 to cost less than £300, which when compared to the iPhone 5s, which starts at £549, means the Google phone will be something of a bargain.
