A Nexus 6 specs concept video on YouTube suggests that the next-gen Google device could include Android 5.0, quad-core Snapdragon 805 processor, 3GB RAM, 5.2-inch display and 2K resolution 2560 x 1440, 13-megapixel camera and aluminum uni-body with the latest version of Gorilla Glass 4. If such a Nexus 6 device is released we likely won't see it toward the end of 2014. Some of the specs such as the 3GB of RAM, 5.2-inch display and 2K resolution are specs that we are anticipating on the Samsung Galaxy S5 so it is not that farfetched to think that the Nexus 6 could have them too. Of course the big issue with this is that the Nexus 6 will require a much larger battery to account for the higher screen resolution and other more resource consuming specs. The Nexus 5 currently has a lackluster and widely condemned 2,300mAh battery. The Nexus 6 will need a minimum of 3,000mAh if not more.

Other Nexus 6 concepts drew on features of the Samsung Galaxy Note 3, "Samsung Nexus 6 uses a 6.3 inch Super AMOLED Plus Full HD screen, the likes of which is rumored to be used on the future Note. There's also an Exynos 5 Octa CPU, probably with big.LITTLE technology, 3 GB of RAM, also a likely feature of the Note III and 128 GB of storage, plus microSDXC. At the back we've got a 13 megapixel camera and upfront a 2 megapixel one, both with Full HD capture. Finally, this device relies on a 4500 mAh battery and measures 9 mm in thickness, certainly a reasonable waistline, considering there are some 4.5 inch phones out there that are much thicker." We consider this to be fairly unlikely, we've seen no indication that Samsung will be producing the next Nexus 6, We expect that if anyone produces the Nexus 6 it will either be LG which has established its capability to make high-quality Nexus devices or Motorola, which is slowly coming into its own as a Google company with the Moto X and Moto G.

Another Nexus 6 concept video showed what both the Nexus 6 and iPhone 6 might look like. Phones Review UK reported that the video was created by Bob Freking who comes up with interesting concepts for what next-gen devices might look like, though they tend to be somewhat unrealistic and over the top. The Nexus 6 and iPhone HD are shown side by side. The Nexus 6 draws design features from the HTC One and includes an aluminum unibody, 5-inch Full HD Super LCD 3 touchscreen display and a super futuristic 6-core Snapdragon 1000 processor (Snapdragon 805 has only just been released). On top of that Freking suggests 6GB of RAM and a 64-bit processor. There's not doubt that these Nexus 6 specs will never happen. In addition to being futuristic and unrealistic, the cost of producing a subsidized device with those kinds of specs and build would be prohibitive for Google and whoever was chosen to build it. It's worth remembering that the appeal of a Nexus device comes from having flagship specs at a subsidized cost, to make up for the lower cost Nexus devices often only have a plastic build, lower megapixel camera or weaker battery.

Future Google & Apple superphones conceptualized - the Google Nexus 6 and the Apple iPhone HD. Take your pick, choose your weapon.

The Nexus 6 concept that we find most attractive and appealing in terms of design can be found on introoo. The Nexus 6 concept is suggested to be built by Motorola wand includes a highly attractive "X Envelope design". The design, explained below, features a very good look for the Nexus 6. This is a fairly old concept though so the specs are somewhat dated but there's no doubt it's a very good looking concept:

Nexus 6 brings you the best of Android experience in the new body. "X Envelope" is the new concept for design strategy of Nexus hero device made by Google and Motorola. Just try with Android 6.0 Milkshake and spatial gestures recognition. Edgy backside with characteristic "X Envelope" signature. Characteristic edgy body made from semi flexible materials and composite. This "X Envelope look" defines the new design direction for new Nexus products family. This brings you the new feeling from daily use and touch your high-end technology piece.

These special designed edition brings you customized prototype experience of your device. Some of the parts could be directly customized especially for you throughout the manufacturing process. And of course, you can 3D print your own unique chassis. Open-hardware distribution should be available.

These aren't the only Nexus 6 concepts out there, all of which present some interesting improvements to the Nexus 5. The main problem of course is that they are dream devices with unrealistic specs and design features. Our bet is that the Nexus 6 (if it is named the Nexus 6 and not a refreshed Nexus 5) will have a 5.2-inch curved screen display, 3GB of RAM, a quad-core Snapdragon 805 processor, 3,000mAh battery and plastic body with a 13-megapixel OIS camera. This is based on examining devices like the LG G Flex, Samsung Galaxy S5, Samsung Galaxy Round, HTC One 2 "M8". The Nexus devices follow common market trends so this is our more realistic estimate for what we can expect the Nexus 6 specs to be. It will of course naturally run whatever the latest generation of Android is, whether it is Android 4.5 or Android 5.0 or even Android 6.0.
