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

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?

6.8 inches.. yahoo! Now that's what I am talking about.. a true phablet unlike the other 5.5 inch puny pretenders out there. I can see Asus responding to the inevitable launch of the xiaomi mi max phablet here in India and have tried to one up it by launching an even bigger device with same specs. They can't compete with xiaomi's price so I guess they are launching it early. As long as it's priced under 15000 rupees, I can see many people buying it.

I have to disagree. But maybe I'm biased as I've grown up building computers with their parts for the last 10+ years.

My only complain is that the home button is a house.

So no form of quickcharge for the base model? Need quickcharge these days especially with a battery of that size! Might have to start saving for the deluxe then

@Peter K.and @PhoneArena - Asus is quite explicit about screen to body ratio for ZenFone 3 and ZenFone 3 Deluxe. 75%+ screen to body ratio is impressive. Where do i find the mention of it on PA? No mention on the news item or specs page.

Good screen-to-body ratio is easy to achieve on large phones, so it is hardly impressive.

quick to debunk, eh? i know your half understood reply. didn't i mention Asus's name here? they are not known for good screen to body ratios. LG, Moto and the likes - yes! let's not talk about (other) large phones. let's be specific about Asus. Changing things drastically is impressive in my book. So don't debunk with quick opinions - internet gives you cowardly freedom to debunk or troll. Let's talk topic for a change.
