There is a wide variety of smart phones in the market and whenever new optimizations are added both in their processors such as cameras and screen. Here is a guide with the most important points to consider when buying a mobile.

the processor

the processor is the heart or brain of the team. In principle, the more cores the chip has, the better, as this will give the mobile phone a higher processing speed. The phones pixelfor example, have the Tensor processors, which stands out by offering a configuration consisting of two high-performance 2.8 GHz Cortex-X1 cores, two 2.25 GHz Cortex A76 cores and four low-power 1.8 GHz Cortex A55 cores. On the other hand, it incorporates a dedicated Titan M2 security chip.

On the other hand, Apple A15 Bionic This is the latest generation of mobile processors from the Cupertino giant and it also stands out for its power and energy efficiency. Also worth mentioning the latest generation of processors Qualcomm, MediaTek Yes Exynos.

RAM memory

The RAM memory or RAM it is used to store data that will be needed in the short term. The operating system is responsible for managing the access of applications and other system elements to the RAM memory so that these services temporarily store the data, with the aim of making them available when needed.

On most modern equipment, android includes integrated RAM management this helps to optimize the use of available spaces in this resource so that they can be used by applications, as needed. For optimal performance, you can aim for a computer with 8 GB of RAM.

For those who make intensive use of the mobile, able to have several applications open simultaneously and who use services that consume a lot of telephone resources, you should aim for at least 12 GB.

the space of storage it is very important especially for users who want to have their photos, videos and documents on mobile. Although it is true that there is the possibility of saving the cloudsome may also want to keep this content on their computer to have it close at hand even when offline.

At present and given the amount of material shared from and to mobile, it is necessary to think about having at least 64 GBeven though ideally, you could be aiming for a 128GB or 256GB computer. It is true that in the case of Android you can use external memory to expand this point.


The first aspect is to consider the types of glasses you have the camera. Cameras incorporate different lenses, and each performs a specific function or provides the user with a unique view, expanding creative possibilities.

Most common devices they equip a wide angle lens and a macro pTo capture places with a larger field of vision or on the contrary, to have all the details of small objects such as flowers, animals, etc.

One of the points to take into account is the megapixels (MP) offered by each of the lenses. The higher the MP, the greater the amount of information the image receives, so photos with much more detail and a greater dynamic range of colors in each photo could be obtained.

Another question to consider is whether you have artificial intelligence to help process images and optimize aspects such as light. In this way, for example, good shots could be taken in low light conditions or at night.

When analyzing the screen, the first point is to know whether it has LCD or OLED technology. The latter has become a market favorite as it delivers images with deeper definition, contrast, brightness and blacks. It also stands out for its energy efficiency.

Another point to evaluate is the refresh rate. Nowadays it is better to aim for a rhythm of 120 Hz which allows a more fluid visual experience, which is very relevant for consuming video content and, above all, when playing video games.

Then you have to see the display size. It is generally expected to be around 6.5 inches for comfort, then you also have to consider the resolution. The older the better. QHD+ resolution, for example, is what prevails in the industry.

This is the key to having a good user experience. It is recommended that the equipment has at least a 4000 mAh battery. Again, you have to know if it is compatible with fast charging, which will avoid many disappointments. Another factor to consider is whether the battery can be charged wirelessly and whether it uses the Qi standard, which is the most common.

Water and dust resistance

Here you should see the level of IP protection that the equipment has. This parameter refers to an international standard for the qualification of electrical devices and their ability to respond to adverse situations such as exposure to water or dust.

The protection usually found in smartphones is IP68, which ensures that no dust or water enters the equipment even if it is immersed in fresh water, for up to 30 minutes.
