Asus Zenfone 3 vs Zenfone 3 Deluxe vs Zenfone Ultra: three-way specs comparison

13comments
Tip your hats and bid a warm welcome to the Asus Zenfone 3, Zenfone 3 Deluxe, and Zenfone 3 Ultra! Asus' newest trio of phones will have a solid fundament to build on; a fundament established by the market success of the Asus Zenfone 2 and its multiple versions, including the Zenfone 2 Laser, Zenfone 2 Selfie, and so on.

The most impressive of the bunch is undoubtedly the Zenfone 3 Deluxe, a powerhouse by all means and purposes. Equipped with a Snapdragon 820 chipset and up to 6GB of RAM, a 23MP rear camera with EIS (electronic image stabilization) and a Sony IMX318 sensor, and up to 256GB of native storage, it's the most powerful of the bunch.

What about the Zenfone 3 Ultra? For starters, its biggest highlight is it's, well, size — this one is a 6.8-inch phone. Yep, that's almost 7 inches of phone we are talking about! Another highlight is the 4,600mAh battery inside. Apart from these, it's not a particularly high-end device. There's a Snapdragon 652 chip and up to 4 gigs of RAM, as well as the same 23MP camera unit found on the Deluxe. 

But what exactly are all the differences between the three? Let's take a closer look, shall we?
