Asus ZenFone 2 Review with Specifications


In the year 2015, Asus Zenfone 2 is known for the first Smartphone which have 4 GB of RAM. Asus launches another variant in its flagship Zenfone series which is started in previous year with Zenfone 4/5/6. The All-new Zenfone 2 has a gorgeous ergonomic design and winner of the iF Design Award 2015. Zenfone 2 has incredibly-slim 3.9mm edges. This is more than an impressive engineering feat; it’s a marvel of design and ergonomics, making the Zenfone 2 incredibly comfortable to hold. The iconic ASUS concentric-circle design adorns both the front and rear key, giving a beautiful, tactile effect. This effect is achieved through precision machining that produces circles with a mere 0.13mm pitch, giving Zenfone 2 a premium look and feel. Zenfone 2 is a 5.5-inch smartphone with a body that’s as small as that of a traditional 5-inch device. This incredible engineering achievement was made possible by reducing the bezel width to the bare minimum, giving Zenfone 2 a remarkable 72% screen-to-body ratio.


Asus Zenfone 2 sports with powerful 64-bit Intel Atom Z3560/Z3580 Quad Core processor which has clock speed of 1.8/2.3 GHz and it is the world’s first smartphone with 4GB of dual-channel DDR3 RAM. Featuring LTE Cat 4+ for download speeds up to 250Mbit/s, and a 60ms touch response time, it has 6430 PowerVR 533MHz GPU. Zenfone 2 gives you power beyond your imagination. Intel Exclusive 3D Tri-Gate Transistor: First introduced by Intel in its desktop-class Ivy Bridge processors, Zenfone 2 employs the very same 22nm technology in its 64-bit processor. The Tri-Gate transistors have almost three times (3X) more surface area as compared to planar transistors, enabling more electrons to flow when it in the ‘on’ state. It also improves the transistor switching performance which increases the computing performance and decrease the power leakage. Performance Increase-37% , Power save-50 %.


Zenfone 2’s 13MP PixelMaster camera with its f/2.0-aperture lens captures stunning, high-resolution photos with zero shutter-lag. The industry-leading Low Light mode employs pixel-merging technology to capture up to 400% brighter photos at night or in low-light scenes, without the need for a flash. Backlight (Super HDR) mode lets you see clearly through daytime shadow and Super Resolution mode helps you to capture detailed image. There are many options in PixelMaster for capturing great images and also shooting FullHD videos.

Display and Battery-

Zenfone 2 is equipped with a high-resolution 1920x1080 Full HD IPS display that offers wide 178-degree viewing angles. The staggering 403ppi pixel density renders every image in eye-delighting detail. For the best clarity, brightness and touch responsiveness, Zenfone 2 incorporates exclusive ASUS TruVivid technology. This seamlessly transforms the conventional four-layer design into an innovative two-layer design, with full lamination. Fusing the cover-glass and touch-panel layers eliminates the air gap, bringing everything closer to Zenfone 2’s surface — and closer to your touch. Gorilla Glass 3 with Native Damage Resistance™ (NDR) improves damage resistance and toughness, so Zenfone 2’s display is up to three times (3X) stronger than other glass compositions. Zenfone 2 supports ASUS Glove Touch technology, so it responds to your every touch, swipe and gesture — even if you’re wearing gloves.
Zenfone 2 has 3000 mAh Li-Po battery comes with Fast Charging. ASUS BoostMaster technology is an ASUS-exclusive technology that charges the battery much faster than in traditional devices. With ZenFone 2, you can recharge your battery up to 60% of capacity in just 39 minutes.
Finally Zenfone 2 is really an awesome phone for a price tag of $300/Rs.22,999 in India for ZE551ML(4 GB RAM, 2.3 GHz). It also comes with other variants as ZE551ML with 4GB,1.8GHz/2GB,1.8GHz and ZE550ML with 2GB,1.8GHz,HD Display.
