New Asus Zenfone 5 A501CG Hands On Review : What else can you expect for Rs.7999

Asus has recently released a new Zenfone model, the Zenfone 5 A501CG 8 GB at Rs.7999. This isn’t the old 8 GB model which was previously available, this is a new model even though the model number is the same. Asus said that their Zenfone series received tremendous response on the launch event of this phone. They are not wrong, Asus made a mark in Indian smartphone market with their Zenfone series, especially the Zenfone 5. With the ever growing competition, they felt the need to update their Zenfone 5 to match the competition, and the result of it this phone.

The new model has a dual core 1.2 Ghz Intel Atom processor, in place of the 1.6 Ghz Atom processor in it’s previous models. (Please note that this model is not the Zenfone 5 Lite, which is a flop model that Asus released earlier). We’ll see how this phone performs and has anything else changed on this phone compared with its older brother. Read on for the hands-on review of the new Asus Zenfone 5 A501CG.

Design & Build quality

The general design of the phone is not anything special to get excited about, it is just an average designed smartphone, but the build quality is over the top. Zenfone 5 has got a simple design that some people may say boring, but is good enough to turn some eyes.

Zenfone 5 comes with capacitive buttons on front, and not the now common on-screen buttons. These buttons are placed a little bit in weird positions, the two buttons rest on the extreme edge, contrary to what you can find in most other smartphones. But don’t worry you’ll get accustomed to this positioning once you use this phone for some days. Under the capacitive buttons, Asus have provided a metallic looking trim, which adds beauty to the phone.

The position of the physical buttons is similar to what we can see on most of the other phones out there. The volume rockers and power buttons are placed on the right. The buttons felt very sturdy and clicks very well. The buttons even have a great pattern on it and is great to have.


The phone is fully built with plastic but it doesn’t feel like cheap plastic at all (Samsung, Ahem!). It has got the ultra premium look and finish at the budget price, and it looks like it can withstand some drops and bumps.


The display in the Asus Zenfone 5 is a 5 inch 720p display, which comes with Asus Truvid technology that offers better color reproduction. There is no change with display, this is the same old display that we found in the previous models (not the Lite model, which came with only a 540p display). The display is good and it provides good color reproduction and is pretty bright. The screen of this phone provides good outdoor visibility, the auto brightness also works very well. The viewing angles are also great, it is much better than other phones at this price range. The display sports a scratch-resistant Corning Gorilla Glass.


Processor & Memory

The new Asus Zenfone 5 is powered by the dual core 1.2 GHz Intel Atom Z2520 Processor. This is the same SoC that we saw in other phones in Zenfone series (Zenfone 4, Zenfone 4.5 & Zenfone 5 Lite). The processor is a down step from the 1.6 dual core processor in the original Asus Zenfone 5 A501CG. Even though it is lower powered, the phone doesn’t even feel like it is lower powered and it performs well in daily tasks.

Asus Zenfone 5 comes with 2 GB of RAM, which is the same as that of the previous models, with exception of the Zenfone 5 Lite, which had only 1 GB RAM. This phone has an internal memory of 8 GB, which can be expanded by micro SD card up to 64 GB. Out of the 8 GB internal memory, only 4.4 GB is available to user. One good thing to note that is, the apps and games can be transferred to the external memory (Gamers rejoice!).

Android and UI

Asus Zenfone series comes with their own custom UI, named ZenUI. Similar to Samsung, HTC and LG, Asus chose to design their own custom UI and ship their phones with this UI on top of Android. ZenUI is an awesome skin that is light on resources and provides much more features and looks great. It comes with Android KitKat 4.4.2 (even though it was mentioned in flipkart that the phone comes with 4.3 Jelly Bean).

It is not at all heavy as that of Samsung’s TouchWiz and HTC’s Sense. The interface is slick and butter smooth. It is not at all laggy as other iterations of Android by manufacturers, Asus can be proud that they made a great skin for their devices.


asus zenui launcher

The stock launcher in Zenfone 5 is almost like the stock Android launcher, but it’s skinned with Asus’s own icons for the apps. It makes the launcher feel different from other phones. The app drawer has the usual apps and widgets tabs in the top and downloaded and frequent apps tabs on the bottom.

Notification panel

The notification panel in the ZenUI is great and the quick settings panel also. The quick settings panel is filled with circular tiles, which can be customized. So many useful tiles are present including flash light, boost, quick memo, reading mode and many more. The boost option clears the RAM right from the quick settings. To access the quick settings easily, you just need to swipe down from right side top of the screen.

Power Saver

The Zenfone 5 A501CG also comes with a power saver app, which has 3 modes : Ultra-saving, Optimized mode and customized mode.

Other apps and features

The stocks apps included in ZenUI are good and useful. They include Asus Weather, Do it later, Asus’s own file manager and many more. Other than these, the stock apps such as Dialer, Contacts, Calender, etc. are also skinned. The recent panel is almost stock Android-like, but has an added ‘clear all’ button on the bottom. It also has a file manager app, which looks great. The stock browser is replaced by Asus’s own modified browser, which actually loads fast, but you can always go for other browsers such as UC, Chrome, Dolphin etc.


Asus Zenfone 5 comes with 8 MP back camera, which Asus touts to be enhanced by its PixelMaster technology. PixelMaster is a combination of software and hardware optimizations that Asus made to fully enhance the camera and image quality of the phone. It has been one of the main selling points of Asus phones. The camera performs well and has won so many awards for being the best budget camera phone last year. Take a look at the shots taken with the Zenfone 5 camera. The quality of the images is pretty good for the price.

The camera interface is straightforward and simple. But it is actually different from the stock Android and unique. The app offers many image enhancement options are available, such as Auto, Time rewind, HDR, Selfie, Beautification and many more. Overall, I can really say this phone is a great offering in the camera department.

The front camera is also the same 2 MP camera we saw in the previous version. The front cam also does a great job in capturing amazing selfies.

Camera Samples


The UI is running smoothly without any lag and opening apps was a breeze. The phone also performs well in the Gaming Department. In my tests, it did run high-end games like Asphalt 8 and Dead Trigger 2  without any lag or stutter.

The call quality is quite good, I haven’t experienced any call drops. The call volume is also quite good. The speaker is situated on the back and it provided above-average hearing experience, it is quite loud. One more thing, there is an option to record calls automatically in ZenUI, which is not available on many phones.


There is no change in the battery department, it features the same 2110mAh battery which came with the older model. But with the inclusion of this lower-powered processor, Asus has managed to somehow to provide a better battery life in this model (not great, but better than the old model). It gave a full day of battery, with moderate usage.


The new Asus Zenfone 5 A501CG is a great choice for a budget smartphone. With the new price cut, Asus can now stand on its feet on the newly developed competition in the market. This phone will definitely give Xiaomi Redmi Note 4G and Yu Yureka a run for its money.

The new Zenfone 5 has got everything to be desired on a smart phone, including the build quality that you just can’t find in any other phone on this price, an awesome camera. And also don’t forget the silky smooth ZenUI and the performance it offers with the Intel Atom processor.

Everything considered I can assure you that this is one of the most value for money phone you can get for 8K and you won’t go wrong buying this phone. You can buy this one exclusively from Flipkart for Rs.7999.

  1. Yes abhi.

    asus zenfone is realy very good smartphone. I am also want to buy this phone. I much needed a review of that phone. Thanks for review.

  2. Recently i bought this mobile. When used for the first time battery draining quickly while just using 2g net. And shall i need to charge for 6-8 hours for gud battery backup.

    1. You don’t need to charge the phone for this much time, but charging for about 8 hours is recommended in the first charge (and the first charge only). Actually, you shouldn’t charge the phone for continuously after it has been fully charged (i.e, after 100% is reached), it’s bad for smartphone batteries to be on charging mode for long hours. Just keep the phone in charging till it is fully charged, you’ll be good.
      And with the battery drain issue you mentioned, can you please point out the screen on time you’re getting with 2G data connection ON?

    1. Not much. The phone is powered by a lower powered processor than the original Zenfone 5, as a result of this the phone is not a heater ( 😀 ) and it doesn’t heat up that much. But it does heat up with heavy gaming and using when charging (this is a common problem with all Android phones).

  3. Dear abhijith pls mention me wat u meant by the moderate usage?
    And also I want to know suppose the phone will remain in 2G and or 3G-on mode for whole day, how much will it last for?

    1. With moderate usage, I meant the usual usage where the phone is used just for casual browsing, with a bit of gaming and video, also checking Facebook and WhatsApp time to time. (No heavy or continuous usage involved)

  4. A great review Abhijith!
    Two things,
    The images cannot be opened in their original sizes. Will it possible for you to upload or mail me at ( few original images?
    Secondly, and most importantly,Can you tell (based on your usage) how much exact hours were you able to clock with full time 3G and 2G respectively on? I only want it for normal data usage (like mail reading/whatsapp and not youtube or video). Say my phone will remain in 2G and or 3G-on mode for whole day, how much will it last for?



      1. I too want to know abt the same question….as of neeraj…how long will the battery last for if i continuosly use 2g and/or 3g for mainly whatsapp and browsing…

        Thank you

        1. I haven’t really tested the phone with continuous usage with FB or WhatsApp, but it holds good, as per the feedback I got from my friend who is using this phone. (It was his phone used for the review).

  5. Abhijith,

    Asus has officially declared that they will give update of Lollypop with Zen UI in April,2015 to All Zenfone 5 & 6.

  6. Hi, what about the Android L update for this latest zenfone. The original zenfone 5 is sure to get that update. Please share whatever info you have on this matter.

    1. There is no official word about that till now. But I’m pretty sure it’ll be released along with the updates for the previous model. Asus released the KitKat update around the same time for all their models, even though all of the phones are having different SoCs.

  7. can you give any further details on benchmark scores for this device also is the processor same as that of asus zenfone 4 ???
    I am thinking about buying this device just concerned about performance of this device .

    1. Benchmarks doesn’t speak about the performance really, what matters is the user experience. That’s why I didn’t include benchmarks in the review. But I have checked the AnTuTu and Quadrant for you, AnTuTu score : 18128 and Quadrant : 7210.
      Both of these are similar to the Zenfone 4.5 model.
