How to choose an Android smartphone

android smartphone

In the next paragraphs you will find all the information you need to know to consciously purchase the best Android smartphone that suits you and your use. That’s why, before starting, I would like you to spend a few minutes reading the features that distinguish the different models to find the best Android phone for you. This way you will be more informed before finalizing the purchase and you will be able to consider yourself a satisfied user once you have made your purchase.

Processor and RAM


We can draw a comparison between the smartphone and the human body: in this case, the processor could be the brain, while the RAM is the memory. The processor, also called Central Processing Unit (CPU) or System on Chip (SoC) , is, as just mentioned, the beating heart of every Android smartphone: it is thanks to its calculation capacity that we can do any operation with our device, and from Its performance depends on the overall performance of the terminal.

A processor is usually composed of multiple physical components, called cores : these small units are designed for pure calculation. In addition, the processor is made up of other parts such as the Image Signal Processing (ISP) which comes into action when taking photos or recording videos, to improve the performance, and the Graphics Processing Unit (GPU) , which manages the graphics calculations , such as those needed to display the user interface and play Android games .

The power of a processor is given by its ability to complete calculations more or less quickly and is measured in Gigahertz (GHz) : the higher the speed expressed in GHz, the more calculations it will be able to complete in less time. There are many companies that produce processors for Android smartphones but the best known ones are Qualcomm , which often supplies CPUs for mid-to-high range devices, MediaTek , Exynos and Kirin .

Without a processor the phone cannot complete any operation, but RAM memory is equally important . The latter allows the system to store and exchange information very quickly, both with the processor and with the physical memory of the device. The larger the size of the RAM memory, the more data the smartphone can always keep on hand for ready use: this is why it is important to have a good amount of RAM memory if you intend to use many applications at the same time.

The capacity of the RAM memory is expressed in Gigabytes (GB) and nowadays the minimum quantity to be able to operate with a smartphone and a good number of apps is at least 4 GB , even better if the phone incorporates at least 6 GB of memory .


android smartphone display

The technology used for the display of a device is an important selection criterion during the purchase phase. Ask yourself the following question: what will I use my Android smartphone for most? If the answer is to watch a lot of multimedia content, especially in the evening or when you are in bed or on the sofa, then you should lean towards choosing a display with AMOLED technology .

AMOLED screens are characterized by absolute contrast, deep blacks (as the black pixels are effectively turned off) and vivid colors: ideal for enjoying content, but they cost more than the more popular IPS LCD displays , which do not have absolute blacks but they can still be of excellent quality.

The resolution of the display , i.e. the quantity of elements present on the screen, is also important. Each screen is in fact made up of many small pixels and the resolution defines the quantity of these “little lights” on the vertical or horizontal axis. A good resolution to have more than sufficient image quality for viewing content is Full-HD (FHD) , where there are at least 1080 x 1920 pixels: in fact, it is easy to find acronyms such as Quad-HD and Ultra-HD , where the density is two or even four times higher than Full-HD. There is also HD resolution , with 720 x 1280 pixels, the lowest of all. Sometimes you may find the + symbol next to the resolution indication: it means that the aspect ratio used includes a greater number of pixels than the resolutions just mentioned. However, remember that a more robust screen negatively affects battery life.

In recent years it is easy to find the display refresh rate indicated in medium-high range phones . Smartphones normally operate at 60 Hz : this means that the image on the screen is updated 60 times per second. A higher refresh rate, such as 120 Hz or 144 Hz , results in smoother use of the interface and viewing of apps and, above all, games.

Finally, the size of the display : a mostly subjective question, but which also has technical implications. The display size is measured in inches taking the diagonal of the screen, and has grown on average over the years: today it is not difficult to find smartphones with a size of 6.8 inches or more, which until a few years ago would have been considered phablets if not even tablets.

When buying a low-end Android smartphone, pay attention to the screen resolution relative to the size . While a Full-HD or Full-HD+ resolution is more than fine on a 6.5-inch screen, an HD or HD+ resolution on the same diagonal would result in content that is poorly defined and even grainy to your eyes.


android smartphone cameras

One of the qualities most advertised by Android smartphone manufacturers is that relating to the photographic sector , but you must be careful. It is not always possible to understand the photographic capabilities of a phone by looking at simple numbers. Let me explain better: data regarding smartphone photographic sensors are often measured in Megapixels (MP or MPX).

A greater number of Megapixels corresponds to a more resolved and detailed photo, but the final result of a shot is dictated by other factors: post-production software algorithms, optical image stabilization mechanisms (both software and hardware), image quality lenses used and so on.

Then there are other factors to consider: the opening of the diaphragm of the main sensor, which indicates the ability to capture a greater quantity of light; the presence of wide-angle or telescopic lenses, so as to offer greater variety when capturing shots; the software on smartphones and the advanced options it offers, such as the ability to capture photos in High Dynamic Range (HDR) . You can always fix it later by using the best photo editing apps , but if the initial shot is already of excellent quality the final result will be even more surprising.

The only certain way to know the photographic performance of a specific smartphone model is to form your own opinion by looking at the reviews of other users, for example if you buy on Amazon , or with the help of scrupulous and detailed reviews, such as those created by DxOMark Mobile .

Dual SIM connectivity and support

Dual SIM Android smartphone connectivity

Mobile communication technologies evolve over the years: currently the most advanced connectivity available on the market is that which uses 5G networks . When purchasing, it is best to consider the network technology on which the Android smartphone relies: a phone with support for 5G networks is certainly preferable to the old 4G/LTE standard .

This doesn’t mean that a phone with only 4G/LTE support should be discarded a priori, far from it. At present, 4G/LTE network technology is perfectly capable of meeting your needs. Many wonder why have a 5G smartphone ? One of the answers could be: when 5G technology reaches the same diffusion as the current one, you will be able to fully exploit its potential without having to change your phone.

If for work you need to have two SIM cards operational on your Android phone then I recommend you check whether the model you have chosen has dual SIM support . Some Android smartphones also offer e-SIM support and allow, in theory, to be able to change operator easily without the need to have the physical card inserted into the smartphone housing. However, you cannot use two e-SIMs on an Android phone, at least for the moment.

In addition to mobile connectivity you should also take a look at the spec sheet and understand how Wi-Fi technology is supported. The new Wi-Fi 6 standard , which is not supported by everyone, offers several advantages such as lower latency and lower battery consumption. To make the most of your Android smartphone with Wi-Fi 6 you will also need to equip yourself with a Wi-Fi router equipped with the same technology: just take a look at this guide to find out which model to choose.

If you want to listen to music with wireless headphones, also check the Bluetooth version of your phone, in particular if it says Bluetooth LE . This technology saves battery when you connect your phone to other devices that support it, such as smartwatches , fitness trackers and Bluetooth headphones . The most recent versions with better performance are Bluetooth 5.0 and Bluetooth 5.2, so make sure that the technical data sheet of the smartphone you want to buy is equipped with it.

Contactless electronic payments are only possible if your phone is equipped with Near Field Communication (NFC) , a wireless technology that allows you to use Samsung Pay or Google Pay to pay at automatic checkouts and POS. If you want to know how NFC technology works , read the guide I just linked, but make sure your smartphone is equipped with it.

Software updates and security updates

software updates android security updates

An updated phone is safer and offers better features over time: depending on the model you choose, the price range and the brand chosen, the update policy changes, however.

When I talk about software updates I mean those relating to the basic operating system: Google develops that and every year it is updated with a new version: if you want to know the version of your smartphone, follow this guide . Individual smartphone manufacturers such as Samsung , Xiaomi and HUAWEI then customize it: this is why the graphic interfaces and features are not the same for all phones.

Top of the range Android smartphones are those that are usually updated the most over time: they are usually supported by companies for up to two or three subsequent versions of the Android operating system. There is no defined rule and each manufacturer is different.

Google, for example, produces the Google Pixel line of smartphones and promises software support for three consecutive updates, or three years. Samsung, on the other hand, offers four years of security updates, which are different from software updates. Security updates are intended to fix security flaws that could be exploited by attackers, but they do not add new features or change the appearance of the user interface.

Each brand that produces smartphones has its own user interface: Xiaomi has MIUI , OPPO and OnePlus have ColorOS , Samsung has One UI and HUAWEI has EMUI . User interfaces, or User Interfaces (UI) , are a bit like clothes: each hardware manufacturer creates one so that it can fit perfectly on the smartphones it produces. This is why often some features that are present on a Samsung smartphone with One UI are not found on another Xiaomi or HUAWEI phone.

Furthermore, manufacturers such as Xiaomi and OnePlus tend to include important software innovations without updating the version of the operating system. Generally speaking, a top-of-the-range terminal is still updated more often and for longer than a medium-low range one. Evaluating the exclusive functions offered by individual user interfaces is essential, especially for those who use Android smartphones for work .

Other characteristics

Android smartphone IP certification

Then there are additional features that can tip the scales for one model over another, one of which is Ingress Protection (IP) certification . This certification certifies the degree of resistance of the phone to the ingress of fine dust and water with a two-digit identification code, on a scale of 0 to 7 (9 for water ingress). Here you will find more information on the topic.

For example, if an Android smartphone has an IP67 certification, it will mean that it offers total protection against the ingress of dust, as grade 6 is the highest for protection from solid particles; while the number 7 indicates the smartphone’s ability to be temporarily immersed up to 1 meter deep or more in water for a maximum of 30 minutes.

There are smartphones defined as “rugged” which are particularly resistant to falls and the entry of external agents: in this case you could find a value of up to IP69K for the entry of water, or the MIL-STD-810G certification , in which the smartphones are put to the test. A MIL-STD-810G certified smartphone is drop- and shock-proof, waterproof and vibration-resistant, withstands extreme temperatures and does not allow moisture ingress.

Also pay attention to the battery capacity of your smartphone: a greater capacity corresponds, in principle, to a greater autonomy. This is because the battery life of an Android phone depends on several factors: screen size and resolution, processor, user interface, usage mode, environmental factors such as ambient temperature during use and signal strength for the 4G or 5G connection. The capacity of a battery is measured in mAh or milliampere hours : despite the various factors that I have just mentioned, with a value equal to or greater than 3,500/4,000 mAh you usually get excellent results on the autonomy front.

Of course, if you are a “power user”, one of those who really uses the phone in a thousand ways, taking advantage of all the technologies included within it, perhaps you could opt for a phone with a greater capacity: there are excellent smartphones with batteries on the market from 5000 mAh and above.

Speaking of autonomy, we cannot fail to mention the methods for wired and wireless fast charging . Imagine having to leave the house and only having a few minutes to recharge your phone: well, there are smartphones that can recharge almost half of the battery in less than 15 minutes. If having fast charging is important to you, then pay attention to this detail when purchasing; ditto for wireless fast charging, which allows you to quickly charge the phone using wireless induction technology.

Still remaining in the context of those who use the phone properly, also check that USB On-The-Go (USB OTG) support is present . This allows you to connect USB peripherals to your smartphone such as external hard drives, sticks, keyboards, mice and joypads: if you want more information you can find it here .

The highest performing phones also support the USB Type-C 3.0 standard or higher: this not only enables faster transfer speeds, for example when we try to download photos to the computer from Android smartphones , but allows us to do things that would not be possible otherwise.

High-end Android smartphones such as Samsung and HUAWEI offer the possibility of connecting monitors or USB hubs, so you can use them as if they were real computers. In particular, the DeX mode of Samsung smartphones is one of the most popular for those who want to have their personal office always at hand.

Many smartphones no longer have the headphone jack , that small circular 3.5 mm input that allows you to use wired earphones or headphones. Models with a headphone jack are still produced, but these are rare and this standard is being abandoned in favor of wireless solutions or with a USB Type-C connection.

Finally, there is a new category of foldable Android smartphones that has now reached a certain maturity: if the first models were more immature and prohibitively priced, now there are some models that could represent a tempting opportunity, particularly if you take advantage of particular promotions like those put in place by Samsung. A smartphone equipped with a foldable display is certainly very beautiful from an aesthetic point of view, but the larger size of the display once opened could also attract you. Remember, however, there is a price to pay for this innovation and a foldable display significantly affects the final selling price.
