The Asus Zenfone 3 Ultra stands rather tall at 6.8 inches, though this is arguably its single highlight. Specs-wise, it is not as impressive as the 6GB RAM Deluxe phone Asus also introduced, it's just a very good upper mid-range device. Design-wise, it's a full-metal device that comes without any visible antenna lines, and Asus claims this is the world's first phone to do so. Asus also wants you to know that its 6.8-inch monster is pretty well-endowed in the audio department. The phone seemingly arrives with a duo of powerful five-magnet stereo speakers, as well as DTS 7.1 virtual surround support. Oh, and did we mention that the phone arrives with a 4,600mAh battery? Well, we just did. The juicer's so large that you can use the Zenfone 3 Ultra to charge other phones with a 1.5A power output.
