Sony Xperia Z2

The Z2 Tablet is powered by a quad-core 2.3GHz Qualcomm Snapdragon 801 (MSM8974AB) processor with 3GB RAM. That being said, the Z2 Tablet is among the fastest Android devices you can get, breezing through basically anything you can throw at it.

Inside is a 6,000mAh battery, which can turn in 6 hours of continuous playback. Impressive for a for a flagship tablet.
