    Asus Zenfone 6 is one of the most affordable 6-inch smartphones in the market with mid-range specifications. If a large screen is your requirement, this is the most efficient option for you.


Those days are gone when smartphones were just under 4-inch size and were designed to give an upgraded experience over feature phones. Nowadays, smartphones are becoming massive in size and giving similar experience of high-end computing devices within the palms of users. However, there is no certain limit on the size of the smartphones but 6-inch is still considered to be a massive size when it comes to the pocketability aspect of the smartphones. After Samsung, Sony and HTC’s attempt for the large-screen smartphones, Taiwanese company Asus stepped into the market with its Zenfone 6 smartphone. We were using this beast for testing all its capabilities being as a massive smartphone. So here is our in-depth review on Asus Zenfone 6.

What’s in the Box

Asus Zenfone 6 is the superior-most smartphone under the company’s Zenfone lineup. As the smartphone belongs to the Zenfone series, its box is quite similar to the one we earlier seen with the Zenfone 5. There is Zenfone 6 render on the top of the box and Intel’s branding is also there to state the presence of an Intel Atom processor within the smartphone.

Unboxing the box of the Zenfone 6 shows the handset on the top and there is a USB-to-microUSB data cable, AC charger, headset with noise cancellation ear knobs and a user manual under the handset compartment. The quality of the in-box content is quite acceptable and similar to the one we noted at the time of reviewing the Zenfone 5.

Its Design

As Asus Zenfone 6 is a part of the first-generation Zenfone smartphones, its design is quite similar to other Zenfone smartphones which include the Zenfone 4 and Zenfone 5. The Taiwanese company has used a plastic built for making the entire Zenfone lineup, but it is extremely solid in nature and give high-end feel in hands.

The front panel of the Zenfone 6 has a massive-sized display. Below the display, there are three touch sensitive controls for back, home and recent app operations. These three keys have haptic feedback but there is no backlight to guide users under dark. An earpiece is available above the display, just above the Asus logo, and a secondary camera sensor is available on the right of the earpiece alongside an LED notification indicator. The area above the display panel also featured an ambient light sensor and a proximity sensor but both are almost hidden due to pure black color of the front panel. Asus has used a Corning Gorilla Glass 3 protection on the top of the front panel to give users top-notch protection from minor scratches and a metal-finished chin is available at the bottom to give premium looks.

The right side of the Zenfone 6 has a volume rocker and a power/lock key, whereas its left side is completely bare with no controls. Both the keys on the right have metal finish and are ergonomically placed to help the users when they are using the smartphone with one hand. The buttons available under these keys are a bit harder than the buttons available on other mid-range smartphones.

Turning the Zenfone 6 towards its rear shows a loudspeaker grill at the bottom while a primary camera sensor along with an LED flash is available near the top. There is a matte finish plastic-built rear cover with Asus and Intel Inside logos.

The rear cover of the Zenfone 6 is removable and taking it off shows a microSD card and two microSIM card slots. A Lithium-Ion battery is also available on the rear side but it is non-removable in nature and is packed under a thin plastic cover.

The overall design of the Zenfone 6 is indistinguishable from the Zenfone 4 and Zenfone 5. However, its massive display is making the smartphone a giant device with 84.3mm width, 166.9mm height and 9.9mm thickness. These dimensions of the smartphone makes it weight just close to 200 grams.
