Externals: Design and Display

Asus Zenfone 2 measures about 152.5×77.2×10.9 mm and weighs around 170 grams. It is a bit chunkier than other models in this category; however, the design itself is very appealing. A rectangular shape framework with a glass pane and chamfered corners are surely a feast for the eyes. The backside seems to be metal brushed although it is made of pure plastic. The highlight here is the curvy backside, which helps to snugly hold the set in hands. The overall design does resemble the latest LG model phones; however, the curvy back remains the signature style of Asus.

Another new thing observed in the design was the placing of volume rockers right beneath the camera on the rear side. This is the first time any smartphone has envisaged such kind of design, although it seems a viable option. The power button is placed on the top center, which is not quite appealing. It makes the switching on and off of system a bit difficult. The bottom contacts the socket for charging, which is also the USB port.

The back cover is removable and once removed one can see two slots for inserting the SIM cards. A 3000 mAH Li-on battery is also placed on the backside, but this is non-removable. Probably, this is a strategy by Asus to ensure that only their products are used and are not replaced by a battery of other models. The front panel sports a 5.5-inch screen with the front camera and the LED flash sensor at the topmost part. A little chin can be seen below the back, home and menu buttons, which seem to occupy space without being of much use. It would have been better to remove it and use that space as part of the screen. The overall design seems good and regal, and the phone is available in colours of red, golden, black and silver.

The display of the screen is quite attractive. It spots a 5.5 inch screen, which is coupled with a dual flash mechanism to capture pictures in correct brightness and contrast. The 16 M palette provides the bouquet of options to capture the perfect colour. IPS panel helps to give a better viewing angle and also enhances the phone with the features of capturing proper images in dark as well as in exposed sunlight. Though some blurring is observed in the dark, the display does an overall good task. It boasts of a modest resolution of 1920X1080 pixels at approximately 403 pixel densities. The display is protected by corning Gorilla Glass 3, which saves it from scratches. So, there is no surprise as far as the display was concerned.

Internals: Hardware and Software

Running on 64 bit Intel Atom Z3580 quad-core clocked at 2.3 GHz, the hardware promises a powerful performance. The phone has been found to be very responsive, and no lag has been encountered while navigation or at the time of using a particular app.

The battery of 3000 mAH Li-on does a great job of supporting the life for more than 7 hours duration, which seems average considering its other counterparts in the market. With a 4 GB Ram, the hardware of Asus Zenfone 2 does a great job of supporting the software.Asus Zenfone 2 Review (3)

This model supports the latest version of Android v5.0 Lollipop. In addition, it has a skin of ZenUI atop it. This additional software has some great features such as floating notification, pull down animation options and a guest mode. The phone comes preloaded with loads of in-house software, which sadly cannot be uninstalled. There are, however, some useful software’s such as Do It Later app, which helps to save the emails and the notes for future usage. Shortcut customizable options are also available. Overall, the software seems to be promising.

Camera and Connectivity

Camera quality is quite decent as Asus Zefone 2 boasts of the 13-MP rear camera, which has a resolution of 4128 x3096 pixels. Supported by the dual LED flash, it is capable of taking decent photos. The 5-MP front camera does a great job for capturing selfies as well as aids in video conferencing. Videos can be captured at 30 fps with 1080 pixels. The cameras use the signature Pixel Master technology of Asus, which claims to increase the brightness and the light by 400% to ensure that pictures can be easily taken in the dark conditions too.

It does a decent job. Apart from geo-tagging, auto focus, smile and face detection, the camera supports many modes such as HDR, Panorama mode, timelapse, miniature and manual mode, which is one of the core highlights of the phone. Though we did encounter blurriness of images when exposed to sunlight, the overall camera can be rated as average.

Connectivity options for Asus Zenfone 2 consist of standard Wi-Fi, Bluetooth, GFs and NFC. It supports 2G and 3G network. An additional feature is a radio, which is definitely an add-on for the phone.


Asus Zenfone 2 seems like a complete package, which is spun in affordable cost. The display, hardware and software are the most appealing factors, which are sure to attract the users. The dual SIM is again a feather on the cap. However, the average camera feature along with non-removal battery seems a little flimsy. But, with the advent of 4GB RAM, Asus Zenfone 2 has surely embarked a new era of smartphones.
