Asus Zenfone 2 4gb ram model review:

We tested the zenfone 2 for about 40 days before publishing this review and received about 4-5 updates which has improved the experience frequently. The model which we have is a 4gb ram model with 32gb onboard storage(Black). The below review is our honest opinions about the smartphone. We have the review unit and not the retail unit so there might be a chance of slight difference in your unit.

Build Quality & Overall Design

Asus Zenfone 2 Build

The Zenfone 2 looks very refreshing and big at first but feels very solid and good in hands. The quality asus has used to make this phone is Quite great. The front look of the Zenfone 2 is very simple yet beautiful.

The phone from the back looks absolutely stunning thanks to the brushed aluminium effect back cover although the backcover is fully plastic. There is Asus branding under the camera joined with intel. Under intel branding we find the Speakers Grill.  Under the backcover you will find the camera module with two dual sim ports and a microsd card slot. Sadly the battery is not removable. It seems asus got inspired by LG’s design of the volume rockers at the back which is something not preferred by most of the smartphone users.


The display the zenfone 2 features is absolute amazing and is one if the best factors about this phone. It is 5.5 inch full HD 1080p IPS panel with a pixel density of 403ppi. For protection the Zf2 comes with Gorilla Glass 3. Also we notice the auto brightness mode of Zf2 to be very dull and bit dark so avoid using auto-brightness mode and go with manual the screen quality will be much better.


The Zenfone 2 comes in many variants. The One we have is a 32 gig model. It also has a support for a microsd card slot expandable upto 64gb. If you like more storage there is a 64gb model too. There will be no issue of storage in Zenfone 2 series due to microsd slot.

The battery hosted by Zenfone 2 is a non-removable 3,000 mah Li-Po. The battery back is below average on this device due to lots of bloatware but we have seen it improving a bit after updating but still the backup is not good as some of its competitors. This is also one of the cons about Zf2.


The Zenfone 2 is priced at approx 20,000 at flipkart and we believe it is reasonable when we see the specs it offer at this price.





The zenfone 2 has a 13mp rear camera with a 4:3 ratio and comes with Asus own technology “Pixel Master”. The camera was quite popular and we expected it to be great but regardless it was just average nothing too good. The front camera is a 5MP which gives fair output quality. It also has a dual tone led flash for natural lighting under low light.
Coming to video recording the zenfone 2 can record upto 1080p@30fps. The quality is again average and dynamic range is very much limited. So camera is another section which leaves a bad impression about this device.

The zenfone 2 has all latest connectivity such as GSM/HSPA/LTE. It is dual sim (Micro). It comes with all latest sensors such as Accelerometer,Gyro etc. Ofcourse it has wifi, wifi direct and hotspot. It also has bluetooth 4.0, gps and Nfc which lots of manufactures are forgetting to add.
So in connectivity category the ZF2 will not disappoint you in any way.


Well the zf2 scores at a whooping in the Antutu Benchmark, It also has 2.3 ghz intel quadcore atom processor and 4gb ram and you can check the below video for a better look at performance.


Well the Zenfone 2 is a great phone to buy if you can compromise on Camera and a little on battery. Zenfone 2 is the best phone to buy for people looking for a good storage as well as big phone with all connectivity features. For buyers which specially want a good camera please don’t consider it as you are better off with Xiaomi Mi4 64 GB Variant. You can also watch our Video Review Of Asus Zenfone 2.
