Asus ZENFONE 4 (ZE554KL) Review: a mid-range smartphone that has fascinating features for an impressive price

When it comes to acquiring a new terminal the options are almost unlimited, since we have an incredibly wide variety of models for all tastes, but we must admit that in many cases we will have a common limitation, the price, which represents that thin red line between the best of the Smartphones available, comparing it from the one that can hardly open the facebook with the one that has all the functionalities, although it is never too clear that some of these dream terminals can be exaggeratedly expensive for what they will really provide. Therefore, for all these needs comes a manufacturer that achieves a point of balance, Asus, a Chinese company that specializes in mid-range devices with very affordable prices, one of its best examples being the Asus ZenFone 5, an elegant and economical Smartphone , but on the other hand, our protagonist also manages to gather the key features of this brand, the Asus ZENFONE 4 (ZE554KL) is emerging as a device that has everything necessary to consolidate in this market.Asus ZENFONE 4

Asus ZENFONE 4 (ZE554KL): Box

The Asus ZENFONE 4 (ZE554KL) comes in a box with the following dimensions: 17.00 x 9.00 x 8.00 cm and has a weight of: 0.420 kg, positioning itself as a package of standard measures that will not represent a higher cost when transporting it and inside the same we will find everything necessary to enjoy this new product:

  • 1x Headphones
  • 1x Power adapter
  • 1x USB cable
  • 1x SIM needle
  • 1x User’s manual

Asus ZENFONE 4 (ZE554KL): Design

The Asus ZENFONE 4 (ZE554KL) opts for a minimalist design that focuses on giving us a structure free of unnecessary embellishments that can saturate your image, resulting in an elegant and refined style, which adapts perfectly to any environment, whether in the comfort of our homes like at work. This device is categorized with softly rounded edges, which are a wonder to both the eye and touch, on the other hand, it is available in 2 colors, black and white, a couple standard versions that allow us to appreciate each one delicately of its details, although we do not discard that in the future we have more options.


This Smartphone is made of metal, a material that gives it greater resistance against shock, falls and scratches, but without reaching the degree of being rough, so we should not abuse this feature since we do not know its inflection point . We must also emphasize that it has the following dimensions: 15.54 centimeters long, 7.52 centimeters wide, 0.75 centimeters thick and has a weight of 0.165 kg, shaping as a device quite comfortable to use even with one hand and as for its peripherals and interfaces we have the following:

  • 1x Nano SIM card slot
  • 1x Micro SD card slot
  • 1x 3.5mm headphone jack
  • 1x Microphone
  • 1x Speaker
  • 1x Micro USB port type C


Asus ZENFONE 4 (ZE554KL): Screen

The Asus ZENFONE 4 (ZE554KL) comes with a capacitive IPS 5.5 inch screen with a resolution of 1920 × 1080 and a density of 401 pixels per inch (PPI), in other words, we are dealing with a Full HD 1080P, which will be combined with IPS technology to enjoy much more vivid and clear colors thanks to the fact that it manages to avoid the loss and leakage of light, a problem that, in general, tends to degrade darker colors. Another important detail is the inclusion of Corning Gorilla Glass 3 protection, so it will be much more resistant against shock, falls and scratches.


We must also add that this screen covers only 71.64% of the front, being outside the range of full-screen terminals and finally, opts for the curvature 2.5D, which does not offer any improvement at the level technical, but if it highlights its beauty, thus achieving a more beautiful screen.

Asus ZENFONE 4 (ZE554KL): Hardware

The Asus ZENFONE 4 (ZE554KL) is characterized by offering a very affordable mid-range section for our pockets, which we must admit, delights us with a performance that meets our needs, that is why below we will break down all its components.


First of all, we have the processor, this being a Qualcomm, exactly the Snapdragon 630, which comes with 4 ARM Cortex-A53 cores that work at a frequency of 2.3GHz and 4 other ARM Cortex-A53 cores that work at a frequency of 1.8GHz, shaping itself as an Octa-Core device. Moving on to the graphics card (GPU), we have at our disposal a Qualcomm Adreno 508 that is combined with a 4GB RAM and a 64GB ROM, the latter being expandable by a micro SD card up to a maximum of 2TB, a quantity literally absurd in our opinion.

Asus ZENFONE 4 (ZE554KL): Operating system

The Asus ZENFONE 4 (ZE554KL) comes with an Asus ZenUI 4.0 operating system, which is based on Google’s popular free software, Android 7.0 (Nougat), so we’re dealing with slight touches of customization from the manufacturer, as well we will enjoy a smooth performance without annoying waiting times, being an enriching experience from start to finish. On the other hand, the classic store of Google Play will continue to delight us with all kinds of applications for tastes, although this is not all, as the Daydream store will also be available with all kinds of virtual reality content and finally, the multi-window function offers us the possibility of executing 2 applications simultaneously with the screen divided into 2.


Asus ZENFONE 4 (ZE554KL): Battery

The Asus ZENFONE 4 (ZE554KL) has a non-extractable lithium-ion polymer battery with a capacity of 3300mAh, which ensures us to easily accompany us for a full day of work with a moderate use, even resisting up to more than 20 days in standby mode. And finally, comes with the technology of fast charging, which assures us that in a period of approximately 36 minutes will be charged completely.


Asus ZENFONE 4 (ZE554KL): Camera

The Asus ZENFONE 4 (ZE554KL) comes with a configuration of dual main camera of 12 megapixels and 8 megapixels respectively, which have a Sony IMX362 Exmor RS sensor that is complemented with a dual tone LED flash to offer us better results, getting incredible photos as long as we have good lighting, that is why in the absence of this, you will notice a little difference in quality, but nothing that is alarming. Here we will present the most characteristic features:

  • Touch focus
  • Autofocus
  • Panoramic photos
  • High dynamic range mode
  • Face detection
  • Digital Zoom
  • White balance
  • Selection of scenes
  • ISO sensitivity settings


And now moving to the front camera, we have a resolution of 8 megapixels that will fit perfectly to take as many selfies as we want, but again we perceive the same detail as the main one, in the absence of good lighting, the quality of it will decrease.

Asus ZENFONE 4 (ZE554KL): Wireless connections

The Asus ZENFONE 4 (ZE554KL) comes with a fairly stable network section, which does not offer us any innovation, staying literally in the standard, although it does not detract from its charm, since it manages to adapt very well to our needs, however for this we must take into account that our Internet provider must be decent. Below we present the connections, bands and configurations compatible with it:

    • WiFi: 802.11 ac
