Features of Zenfone 3 Ultra

Display and Dimensions

At the first glimpse, we could experience the magnificence of the metal aluminum crafted in a sleek, diamond-cut unibody of the phone. It is engineered with the perfect balance of sleekness and strength, coated with a hyperfine sanding process and polished to beautify it with a smooth finishing. The antennas are integrated in such a way that they cannot be traced, however, they provide the world-class signal strength and gapless beauty. The phone comes with a 6.8mm thin edge and 0.18mm diamond-cut bezel that feels impossibly smooth when gripped in hands. With a 6.8-inch FHD IPS+ display, we could find extreme clarity in its images and graphics that brings out lifelike pictures. It comes with the ASUS Tru2Life+ technology that delivers a superb contrast and sharpness in the pictures to deliver stunning and lively images.



The Zenfone 3 Ultra comes with a 1.8GHz, 64-bit Qualcomm Snapdragon Octa-Core processor, delivering super-fast content and graphics. We could experience lag-free contents and could easily access multiple apps at a time. The Adreno 510 graphic processor generates clarity images and graphics that bring every motion come alive. With advanced multitasking, the phone lets you browse through different apps and videos without causing any interruption.


The phone is equipped with a huge 4600mAh battery that supports quick charging with the Qualcomm Quick Charge 3.0 technology. The battery keeps you entertained for long and talk as much as possible. The battery also supports reverse charging, which means it can also be used as a power bank. We tried charging other smartphones and mp3 players and could see 3 times faster charging with its 1.5A output.


We can say the Zenfone 3 Ultra battery is ready to perform under any condition. The phone also consists of a Fingerprint sensor that can unlock the phone within a fraction of seconds. The Fingerprint sensor is positioned in a friendly location so that it can be easily accessed while holding the phone. We could register up to 5 recognizable fingerprints with 360-degree recognition.


The Zenfone 3 Ultra is packed with a giant 23MP rear PixelMastercamera with 92MP Super Resolution technology, capturing the genuineness of the world. We applied our hands with the Zenfone 3 Ultra camera in daylight, as well as at night, and could find flawless images. We utilized every single mode and due to the optical and electronic image stabilization, the shots are generated as blur-free,embracing true colors. The camera is stupendously fast with instant focus and subject tracking because of the exclusiveTriTech auto-focus technology.


The camera is combined with three major focusing technologies, which includes, laser phase detection and continuous auto-focus. The shots are generated with lightning speed and the close-up images can be focused in 3 seconds. It provides accurate phase detection and super-fast clarity of moving subjects.

With DSLR quality, the camera can detect the trails of incoming light rays and deliver rapid auto-focus with precision. The phone’s camera uses the 4-axis optical image stabilizer and can move the lens in eight directions to prevent shaking and vibrations. This means, the lens remains in its place even if you move the camera or shake it, and every shot takes will be incredibly sharp. In low light conditions, the exposures can be set to longer to capture maximum light without blurring the image. Even the videos shot with the camera remains steady due to the smart software algorithms that prevent shakes and keeps the content sharp.

The camera also uses color correction sensors for accurate colors that prevent the entry of artificial lights or unnatural colors. We tried capturing a few scenes and could find the tangible colors in the captured images. There was no false reproduction of colors or light. It detects the light automatically and configures the perfect settings to obtain the perfect balance of natural colors.

The Zenfone 3 Ultra’s Super Resolution mode allowed us to use the special image processing techniques to every single detail in an image. The burst mode can capture up to 5 photos, combining them into a single image with 4X clarity. The videos can be shot at up to 4K UHD resolution, which is 4 times the quality of full HD. The front facing camera of the phone is 8MP, which we feel that, is too inferior compared to the rear camera. We tried clicking a few selfies with the camera and found them pretty okay.
