Google Nexus 6

The Google Nexus 6 is Google's latest smartphone with a nice, big screen. The 6-inch AMOLED display looks wonderful and the design is very smart.

With such a big screen, the Nexus 6 could have been even larger, but the smartphone packed the screen and bezel into as compact of a size as possible. The Nexus 6 has a big 3,220 mAh battery that will last all day and when users are running low on battery they can utilize wireless charging, according to Engadget.

The Nexus 6, since it is made by Google, has the advantage of getting Android updates before any other devices.
