Asus Zenfone 3 Zoom vs Apple iPhone 7 Plus vs Samsung Galaxy S7 Edge: specs comparison

3comments

The Asus Zenfone 3 Zoom has just made its official appearance at CES 2017, and it's quite an impressive device: a 5.5" phone with a dual-camera system a la iPhone 7 Plus, and a large, 5,000 mAh battery that should last for days.

And while the Asus Zenfone 3 Zoom features the Snapdragon 625, one step short of the flagship-grade Snapdragon 8xx chips, it will likely compensate with a lower price. And there aren't that many affordable phones with top-rate cameras.

That's why we were interested to compare the new Asus Zenfone 3 Zoom against two immediate higher-priced, 5.5-inch rivals: the iPhone 7 Plus for its similar dual-camera system, and the Samsung Galaxy S7 Edge for its similar focus on a larger battery. Let's see how these devices differ in terms of their specs.
