ASUS Zenfone 3 Review: Attaining Zen in Mobile Technology


Asus Zenfone series recently launched a flagship smartphone that aims to be the eyeball catcher in this saturated market. With the Zenfone 2 series, Asus gained a potential market share in India and is now a well-established brand with an excellent price to value products portfolio. The Asus Zenfone 3 series is the latest entry in the country which aims to bank on its unique design language, So how well does the Zenfone 3 perform? Does it add the required fuel to the brand? Let’s find that out.



The USP of the Zenfone 3 is its design; the glass back looks clean and elegant giving it a premium look. The device is slim at 7.7 mm though it does pack a massive 3000mAh battery. There is a metal rim running around the corners of the device which makes the device a bit heavier to hold.


Moving on to the body of the phone, on top you find the 3.5mm audio jack and a secondary mic for noise cancellation. On the front, you see a 5.5-inch 1080p display, primary microphone, an 8-megapixel front camera, three touch type capacitive buttons that aren’t backlit like any other Zenfone Smartphone and the usual set of sensors. To the right side, you just have the SIM tray, and on the left, you find Volume rockers and power on/off buttons that are tactile and give a good amount of feedback. Finally, to the bottom, you have the USB Type-C port, speaker grill, and mic.

Though there is no particular complaint regarding the design, one major complaint we have is that the device is slippery due to the glass build on the rear side. We have dropped the device twice by mistake. So, we recommend you to use cases so that you won’t damage it quickly.



The Asus Zenfone 3 sports a 5.5-inches 1080p display with a pixel density of 401 PPI. The display is pretty good and bright with fantastic viewing angles. Watching content on the device should be a delight considering the great color reproduction. The display is visible in broad daylight and comes with Corning Gorilla Glass 3 protection to protect it from drops and scratches. The 2.5D curved glass ensures that the phone fits comfortably in your hands.



The Asus Zenfone 3 is powered by the Qualcomm Snapdragon 625 SoC with Adreno 506 GPU, coupled with 4GB RAM and 64GB internal storage. Talking about the device’s general day-to-day performance, we never really faced any significant lag or drag. However, things change once we start gaming. We played various games like Asphalt 8, Nova 3, Need for Speed run with highest graphic setting possible, and we did notice frame drops and lag here and there but overall it seemed to be an above average performance.

The 4GB RAM ensures proper multitasking, we had opened more than ten apps in the background but never saw lag with the device. Regarding heating, during gaming, we did notice device getting a bit warm which has become quite common for most handsets these days but no heat in general usage whatsoever. Though the benchmark applications are there to calculate the device power, we never actually considered it as a bar to judge a smartphone. To put it in simple, The Asus Zenfone 3 shines with its performance too if you can manage to let go off the occasional frame drops and lag during Gaming.


The Zenfone 3 comes with a 16-megapixel rear camera with f/2.0, laser/phase detection autofocus, OIS (4-axis), dual-LED flash and an 8-megapixel front camera. The device packs in the very infamous owl mode which brings down the camera to 3-megapixel, but the owl mode ensures to give best possible result in extreme low-light conditions which is being proved earlier. It also comes with a Pro mode giving you full control over the settings like ISO, white balance, exposure and more.

Talking about the camera performance, the 16-megapixel sensor is a clear disappointment for Asus, the images shot with the camera are below average and have average color reproduction to them. The images shot under low-light have quite a bit of noise. We tried out the smartphone’s camera under various lighting conditions like low-light, daylight conditions and indoors.


The Asus Zenfone 3 has a lot going on for it but does it justifie the price tag the company is asking? Well, that’s a pretty big question. In this competitive market where companies are coming with flagship chipset like the Snapdragon 820 for a lesser price; Asus should probably reconsider the pricing. However, the beautiful display, below-average camera, and decent performance make it a good buy in the price range.
