There is a wide variety of smartphones in the market and every time 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 because that will give the cell phone higher processing speed. The telephones Pixelfor example, have the Tensor processors, which stands out for offering a configuration made up 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 integrates a dedicated Titan M2 security chip.


Besides, Apple A15 Bionic It 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 Y Exynos.



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

On most modern equipment, Android includes integrated RAM management that helps to optimize the use of the spaces available in this resource so that they can be used by the apps, as they need it. To achieve optimal performance you can aim for a computer with 8GB of RAM.

For those who make intense use of the mobile, capable of having several apps open simultaneously and who use services that consume a lot of phone resources, then you have to aim for 12 GB as a minimum.

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 backing up in the cloud, it is possible that some may want to preserve this content on their computers as well, to have them at hand even when they are offline.

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


The first aspect is to consider the types of glasses you have the camera. The cameras incorporate different lenses, and each one fulfills a specific function or gives the user a unique view, thus expanding the possibilities of creation.

Most current devices they equip a wide angle lens and a macro pTo capture places with a greater range 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 that the image receives, so photos with much more detail and a greater dynamic range of colors in each photo could be obtained.

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

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

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

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

This is key to having a good user experience. It is recommended that the equipment has at least a 4,000 mAh battery. Here you also have to know if it is compatible with fast charging, something that 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 have to 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 that is usually found in smartphones is IP68, which guarantees that no dust or water enters the equipment even if it is submerged in fresh water, for a maximum of 30 minutes.
