What to consider when buying your next smartphone

Criteria such as design, battery life, and storage size are some main factors.

Choosing a new cell phone may be a difficult assignment. If you are a layman in matters related to technology, learning which criteria you must consider when buying a smartphone seems impossible.

The color and the material are relevant? What are the ISO levels? A 64 GB device is enough for me? These and other questions are pretty common when you open a website to buy a smartphone or walk to the nearest shopping mall — and all of it is really important.

Depending on how often you use your cell phone, different criteria may be a priority. If you want a smartphone with your style, a different color, and customization options, the design must be your basis.

On the other hand, if storage is your main concern, it is important to filter the phone options by its Read-Only Memory (ROM). Learn other fundamental important factors to help you.


The processor is the main responsible for the phone performance, allowing it to process photos and videos, open apps, run games, and other important activities. To learn how to evaluate the processor, you might know what the phone cores mean.

Each smartphone may have a different number of cores. Thus, the more cores, the better the performance. The dual-core phones have two cores; the quad-core have four cores, and the most recent phones, with an octa-core processor, have eight cores.

Another important topic about the phone processor is the clock speed, measured in GigaHertz (GHz). It shows how fast the processor runs per second. It means that a 2,4 GHz processor is faster than a 1,8 GHz one, for example.


Every cell phone has two different kinds of memory. The Read-Only Memory (ROM) is the storage we look for in a phone, while the Random Access Memory (RAM) is related to the phone performance and speed, connected to the motherboard.

The storage of the phone is fundamental to most users, especially the ones who do not have time to wipe out the device frequently. Nowadays, with new and modern smartphones, big storage is important to keep heavy photos and videos, as well as countless apps.


Choosing a good camera is important not only for those who use the cell phone for professional activities but also for users that take photos to register personal moments.

With-high quality devices, you may take beautiful photos in special situations, such as marriages and birthdays, or normal days, registering a nice homemade chocolate cake, for example.

To evaluate the camera quality, note specification as double, triple, or quadruple-camera, besides pixel size, the number of megapixels, and autofocus. If you are a selfie fan, remember to check the front camera details.

Battery life

Battery life is one of the most important criteria to choose a new smartphone, principally for people who spend much time out of home and need to use the cell phone with high frequency.

The battery is measured in milliampere-hour (mAh). An average device has around 3000 mAh, as a high battery quality phone presents 6000, 7000, or even more mAh.


The cell phone design may seem irrelevant, but there are good reasons to consider it before buying your device. The arrangement of entries, buttons, cameras, and fingerprint sensor can make the phone easier or more difficult to use.

For example, some devices come with the same entry for earphones and chargers, and it can disturb those who want to use the headset and charge the phone at the same time.

The phone size is also a very important topic. Smaller devices may be bad for those who like to watch series and videos. On the other side, wider screens can be hard to use with one hand, and call too much attention on the street. Thus, remember to evaluate this before buying the device. Finally, if you like to customize your phone with special phone cases, it is also important to pay attention to the device design. Some unpopular models have fewer options, so you may have to use a basic case to style your phone.
