I don’t think the most tensed battle is any longer between iPhone6, Galaxy S5 or standard sized devices but between the phablets because of the extreme juice now put in these phones by the companies. Google Nexus 6 and Samsung Galaxy Note 4 have released within a week of each other. They have all the latest specifications and it is going to be a decision that kills.
Both the phones are superfast with the Snapdragon 805 processor by Qualcomm and each of them come with 3GB of RAM. Phablets are all about displays, if you are buying it you surely prefer the overly large screen. Nexus 6 is designed by Motorola and comes with a 5.9 inch Quad HD display and the Samsung Galaxy Note 4 has a 5.7 inch Quad HD display, so yeah very marginally denser but nothing you can differentiate with the naked eye. Galaxy Note 4 has this really amazing AMOLED display that shines in colours better than the Nexus 6. Samsung is just improving with their displays and they have pulled out a stunner.
Motorola Google Nexus 6 comes with the latest Android 5.0 Lollipop OS and the Galaxy Note 4 comes with v4.4.4 KitKat OS but should be getting the update soon. Samsung Galaxy Note 4 has a phenomenal battery life and there is no way Nexus 6 can better out. The Note 4 comes with a 16MP camera and the Nexus has a 13MP camera. Nexus 6 is available in 32GB and 64GB models and the Galaxy Note 4 comes with 32GB memory expandable to as much as 128GB.
