The Asus Zenfone 3 Ultra is a 6.8-inch monster with a 4,600mAh battery that works as a powerbank

How large, exactly? Think larger than 5.7 inches. While you're on that track, slowly increase the size until you no longer feel comfortable. Did you stop at 6 inches, or even 6.3? That's sweet, but those of you who put a halt around the 6.8-inch mark just hit home.

Yep, the 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.

Here are its specs at a quick glance:

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. We for one hope this trend gets copied at will!Also, despite being branded as a member of the Zenfone 3 family, its design is quite different from the Zenfone 3 and the Zenfone 3 Deluxe. Its fingerprint reader, for example (yes, it has one!), is embedded under a physical home button up front. 

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. You can make use of the latter if you grab yourself compatible certified headphones. 

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. 

The Asus Zenfone 3 Ultra will be available in Taiwan, Asia Pacific, China, and Europe, but there's no word about the USA yet. The 64GB of the phone will cost around $479 once it hits the shelves, though we have no idea about the pricing of the 128GB flavor.
