What is Zenfone?

Zenfone is the name of the basic smartphone line of the Taiwanese brand Asus, which has been conquering . Established in 1989 in Taipei, in northern Taiwan, Asus specializes in the manufacture of hardware.

Over the decades, the brand has become known for producing motherboards, video cards, disk players for companies like Sony, Apple, HP, Compaq, among others.

Today, Asus is the 4th company that sells the most computers in the world. After establishing itself as one of the biggest hardware manufacturers, Asus started investing in smartphones.

In 2014, the brand arrived in with the Zenfone line, standing out for its attractive prices, with cutting-edge designer and tough hardware.

In addition, the Zenfone was marked by good-definition cameras, high-performance batteries and large storage capacity.

The first models of the line launched here were the Zenfone 5, Zenfone 6, Zenfone 2, Zenfone Selfie and Zenfone Go.

Most of them, in addition to the high processing power and attractive cost-benefit, the Asus smartphone models offer the possibility of using two cards (the dual sim).

With all these features, the Zenfone soon became the best option for those who want a next-generation smartphone with lower prices compared to top-of-the-line brands such as Apple and Samsung.

Therefore, since the launch until today, Asus remains well positioned among the main manufacturers in the country, such as Motorola, LG and Samsung.

Today, the brand is considered by IDC Quarterly Mobile Phone Tracker as the fourth largest seller of smartphones. In addition to Zenfone, there is also the line of mobile phones for games, known as ROG phone.

What are the generations and models of Zenfone?

Common among smartphone manufacturers, Asus has not escaped the rule by launching several generations with models of different technologies and functionality. But, in the case of Asus, the name of the devices ended up confusing a little at first.

That’s because, the first generation of Asus smartphones appeared in 2014 with the Zenfone 4, Zenfone 5 and Zenfone 6. These names refer to the number of inches on the screen.

But with the launch of the second generation, Asus changed the strategy and started naming the devices no longer by the size of the screen, but with sequential numbers.

Therefore, in the second generation Asus launched the Zenfone 2. From then on, the new Asus smartphones followed the count in sequence.

But the confusion happened with the launch of the fourth generation, with the Zenfone 4, and the Zenfone 5, of the fifth generation. Did you notice that both have the same names as the first generation cell phones?

And in any case, the name strategy has not overshadowed the brand’s technological innovation. The Zenfone 2, launched in 215, for example, was the first device in the world to have 4GB of RAM.

In 2016, the Zenfone 3 allowed you to “lend” battery to other devices. The following is a timeline of all generations and the main Zenfones released to date:

Check out the main advantages and disadvantages of Zenfone cell phones below:

How much does a Zenfone cost?

The price of Zenfone cell phones varies according to the generation and the models, since each one offers different technologies and resources. But in general, Asus smartphones cost between R $ 550 to R $ 4,500.

Where to buy a Zenfone?

You will find Zenfone for sale in telephone, department stores, and hypermarkets.

However, we recommend that you buy your Asus smartphone at online stores like Amazon. That way, you’ll find the latest models at the most competitive prices. In addition, of course, to make your purchase from the comfort of your home.



Did you know that the name ASUS originated from the junction of the last four letters of the word “Pegasus”? Pegasus is the winged horse that in Greek mythology represents the inspiration of art and learning, creative and agile symbolism.



Purchasing criteria: What to consider before choosing Zenfone

Like all cell phones available on the market, there are differences in technologies and features between one model and another. Zenfone is no different.

In common, all devices come with a charger, data cable, headset, bumper (rubber cover that surrounds the edge of the cell phone) and user manual.

But, in the midst of so many different models and technical specifications, it is important that you take into account your need for use and your routine with your cell phone to choose the best device.

To help you with this choice, we have listed below the main factors that you must observe before purchasing your Zenfone:

  • Screen
  • Processor
  • RAM memory
  • Internal memory
  • Cameras
  • Drums
  • Functions

Next, we’ll detail each of these factors so you can buy the most suitable Asus smartphone for your needs and expectations.


To evaluate the screen of your Zenfone, you must take into account two factors: the size and resolution of the image. The screen size of the Asus smartphone varies between 4 and 6.2 inches.

Of course, the bigger the screen, the better the experience of viewing messages, photos and, especially, videos and games.

But that choice will depend on how you use the device. If you need or prefer to use it with just one hand, the small screen can be more functional.

The screen resolution indicates the number of pixels, bright and colored dots that make up the image. In general, you will find screens with HD and Full HD resolution. HD is increasingly in disuse.

So, if you want a more current Zenfone, opt for the one with Full HD resolution that guarantees better viewing of images and videos.


The processor is the brain of the Asus smartphone and the more powerful the faster the speed for accessing applications. In general, processors are differentiated by the number of cores. And the more cores you have, the greater your speed.

The most modern of the Zenfone line is the Qualcomm Snapdragon SDM845 processor, which has eight cores.

But you’ll also find super-efficient quad-core processors, the Quad-Core.

The dual-core, known as dual-core, although less popular today, can be effective

RAM memory

RAM is essential for the smartphone to be able to perform different activities simultaneously and efficiently.

Therefore, the bigger the RAM memory of your Zenfone the more space it will have to hold and run applications and tasks, and the lesser the chances of it working slowly.

To ensure this efficiency, experts recommend that the smartphone has at least 2GB.

As we have seen, Zenfone 2 was the first smartphone released with 4GB of RAM. But nowadays it is possible to find Zenfone models with up to 8GB of RAM.

Internal memory

The internal storage space is essential to prevent the smartphone from locking up. That’s because the phone’s internal memory is the space available for you to save photos, videos, files, music and data from applications.

You will find the Zenfone with several internal memory options: 16GB, 32GB, 64GB and 128GB.

The most modern Asus smartphones, however, have greater internal memory and even a micro SD card slot, which allows to increase the memory space even more.

Don’t forget that the cell phone system itself takes up part of the internal memory space. Therefore, the ideal is to purchase a Zenfone with at least 32 GB.


In this factor you must take into account the quality and quantity of cameras offered by Zenfone. The quality of the camera will be measured, but not exclusively, by the number of megapixels (Mp), which can vary from 5Mp to 23Mp.

For example, if you want to take pictures to post on social networks, a 5Mp camera is enough to guarantee image quality and storage space on the device.

This is because, the greater the amount of megapixels, the more internal space you will need to avoid compromising storage and image quality.

Another point to note is that, in general, the Zenfone offers two or even four cameras, front and rear. In this case, there will be a Mp difference between them.

Finally, another factor that influences the quality of the Asus smartphone camera is the aperture of the diaphragm, responsible for controlling the entry of light.

In general, openings are determined by number, for example, 2.2, 2.3 and 1.8, followed by the letter “f”. The important thing is that you know that the lower this number, the greater the opening capacity, which results in clearer images.


In general, Zenfone models have a battery power that varies between 3,000mAh and 5,000mAh. This means that the higher this power, the greater the device’s ability to maintain the battery without recharging.

But, of course, the battery life depends a lot on how you use your Zenfone. Using and opening heavy programs, such as videos and movies, and accessing several applications at the same time, will help the battery run out faster.

Remember, some models also offer extra features to measure and help you control battery drain.


In addition to the different technical specifications of each Zenfone model, also check the additional functions of each one. Nowadays the variety of smart features available on the Asus smartphone and that facilitate your day to day is huge.

To give you an idea, the most popular functions nowadays, and available in some of the Zenfones are: virtual assistant, biometric sensors, water resistance, among others.
