Today at Computex, as part of their annual Zen press conference, ASUS lifted the lid on the Zenfone 3 series. In previous Zenfone generations, the Zenfone has been one of the premier devices featuring Intel’s Atom smartphone chipset, however due to the announcement that Intel has cancelled their Atom smartphone ‘Broxton’ program ASUS is going all in with a series of Qualcomm chipsets, including the custom Kryo based Snapdragon 820 and also the first 14nm Snapdragon 625 device.

The Zenfone 2 line is known for having numerous, region specific models over its lifespan. To start, the Zenfone 3 will come in three formats and sizes: the base Zenfone 3 (ZE552KL), the premium Zenfone 3 Deluxe (ZS570KL) and the media-consumption focused Zenfone 3 Ultra (ZU680KL).

We were able to get a quick preview the day before the announcement, and had some hands-on time:

The black model is the base Zenfone model, featuring a Snapdragon 625 (dual 4xA53), and comes with Gorilla Glass 3.0 on the front and sides with 2.5D for the contouring on the edge. This model will feature up to 4GB/64GB, a Sony IMX298 rear camera, 2x2 dual-band 802.11ac WiFi, up to Cat 6 LTE, dual SIM and a USB 2.0 but Type-C based connector. The screen is a 5.5-inch Super IPS+ LCD, and runs Android Marshmallow with ZenUI 3.0.

The gold model is the Zenfone Deluxe, designed to be the high-end model with the main focus on the Snapdragon 820 (using Qualcomm’s custom Kryo cores, similar to the LG G5 and certain Samsung Galaxy S7 models) and having up to 6 GB of memory. So add to this on the storage of up to 256 GB, supporting the UFS 2.0 standard, and an upgraded 23MP Sony IMX318 rear camera and USB 3.0 (again, via Type-C), and ASUS hopes to be challenging some of the high-end devices. The unibody design aims for a seamless rear, with no antenna banding or windows, instead going for a small hole on the side of the phone at the top which, according to ASUS’ internal metrics, should be sufficient. The Deluxe will support Quick Charge 3.0 and has a similar 3000 mAh battery to the base model.


The large 6.8-inch Zenfone 3 Ultra is what ASUS is calling its ‘multimedia Smartphone’, aiming to combine the use case of a tablet with a smartphone. We’ve seen large smartphones before (like the Huawei P8 Max) but these tend to be region focused: I was told that the Ultra will be coming to the US in some form over the next few months. The Ultra runs a Full HD display (1920x1080) like the other two devices, but uses ‘ASUS Tru2Life’ technology based on Pixelworks’ 4K TV processor which also featured in the ZenPad S 8.0. This is supposedly an upgraded version over the ZenPad S 8.0, and it will be interesting to see Brandon’s reaction to it over the ZenPad. ASUS is equipping the Ultra with the Snapdragon 652 (4xA72, 4xA53), with up to 4GB/64GB and a 4800 mAh battery. ASUS is keen to promote that the phone can also act like a power bank and offers reverse charging. The Ultra will also come with DTS HD Premium Sound and Headphone 7:1 support, allowing for hi-res audio support up to 24-bit/96 kHz, and aiming squarely at the multimedia experience.

All three will feature fingerprint sensors, with the base model and the Deluxe having a rear touch sensor, the Ultra having a button sensor on the front, and all three supporting five fingers of recognition. They will all support ASUS’ PixelMaster 3.0 camera features: an f/2.0 6-element lens, 4-axis photo OIS, 3-axis EIS and dual tone LED flash. ASUS wants to promote its TriTech autofocus technology, enabling focus via contrast, phase and a second generation laser (capable up to 1.2m) for a 0.03-second autofocus system (ASUS states that around 250,000 pixels have left/right light detection to aid this).  An 8MP front camera is on the front of all the cameras also.

We’re writing this before the announcement, and we expect pricing to be specified during the presentation along with the time for device rollout.

  • taisserroots - Monday, May 30, 2016 - link

    One has up to 256gb configurable storage, I doubt the delux model needs an sd card
  • taisserroots - Monday, May 30, 2016 - link

    If so it makes the guy who slammed ASUS for not having it look rather stupid and a clear hater, rather than someone who actually cares about the specs.

    6.8" is not a phone. That's a tablet.
  • shadarlo - Tuesday, May 31, 2016 - link

    Which is about time that tablets support cellular capability here in the US... it's been available in 8"+ devices around the world for some time.

    No is not. Just because you think is too big doesnt mean others feel like you. Time to get out of your bubble.
  • taisserroots - Monday, May 30, 2016 - link

    Do all of these models support 24bit 96khz??

    1080p and Snapdragon 820/ Adreno 530 means it will be an absolutely smashing gaming set up with butter smooth 60 fps in all games almost.

    Thankfully, some OEMs have the sense to not use QHD panels in devices less than 7 inches. The hit to the battery and the performance overhead for the extra pixels are not worth it.

    Will surely be considering this.

    Still a little disappointed at not seeing the ZF3 powered by an Intel soc as before. Good to have different socs available with different benfits and drawbacks.
