Smartphones guide: everything you need to know and selection of the current offer

Smartphones are the star devices of the technology industry. With versatility as a flag, from the initial communication capacity, they have been improving features until they become miniature computers that we use for many other tasks such as digital calendar, productivity, photography, or all kinds of multimedia entertainment.

Hence the difficulty of choosing the model that best suits each consumer together with a vast offer that can overwhelm anyone. Despite the slowdown in sales (due to market saturation, lack of innovation, economic situation, and price increase), there is no doubt that smartphones continue to be devices of maximum interest and it is expected that the new formats with the new folding and in connectivity with the final takeoff of 5G will boost their sales again in 2021 as we have already seen in the last quarter of the year.

How to choose the best smartphones

In this guide, we will review all the characteristics that a user who seeks to make the right purchase should assess, but there are a couple of previous sections that should be clear before starting:


What are you going to use it for preferably? The reality is that (almost) the least we do with a smartphone is classic voice phone calls and we use it massively to surf the Internet; use social networks; instant messaging; video conferencing; photos and videos; watch movies or series; listen to music; read e-books; play in mobility; use it as the engine of a virtual reality device and even on the desktop transformed as a mini-PC. Even so, there will always be a preferred section of use, in addition to others such as autonomy or robustness.


How much are you willing to spend? Another important previous key. The average price for mobile phones has increased in recent years and some top of the range exceeds the $ 1,000 barrier. Don't get hot with marketing. Assess your needs and set a maximum budget to invest. The mid-range in smartphones is the most interesting on the market in terms of features/price and has plenty of models for most users. Also, evaluate versions of previous generations. There haven't been too many innovations (except in folding) and they tend to drop in price when new models arrive.


With the above clear, there are a few aspects that differentiate smartphones and whose assessment can help choose the most appropriate for each user. We remind you of the most important ones.

Screens - Resolutions - Technologies

The screen size is one of the first parameters that the consumer must assess. A larger diagonal will increase viewing comfort but will increase weight and make it difficult to use with one hand. Here the industry does not leave too many options. The average size has not stopped increasing in a trend that seems unstoppable and we can easily place it in the 6-inch environment. Underneath there are few, while the largest can even exceed 7 inches.


Regarding the native resolution, the average is around an acceptable 1080p, although there is a variety from the simple HD that is used in the input range. In the high-end we can find 2K and even 4K of a particular model, a real outrage considering its size. Special "stretched" resolutions like FHD + or 2K + are in full swing as designs with 18: 9, 19: 9, and even 21: 9 aspect ratios have become fully established.


In screen technologies, IPS are still the most used, while LCDs are used in the entry range. OLED-derived panels are reserved for the high-end. All are multi-touch and most support the use of stylus pens although the experience is not the best except for specific models with active digitizers. Support for technologies such as HDR10 or Dolby is another of the additions, although perhaps the biggest novelty in recent months has been the increase in the refresh rate above the typical 60 Hz, especially suitable for mobile gaming.

Formats - Designs - Finishes

The new flexible screen or dual-screen form factors have been the biggest novelty of the past year and innovation that the industry hopes will boost sales. Samsung is the most prominent manufacturer with two series Fold and Flip, but there are others such as Motorola, Huawei, or Microsoft that have already marketed these types of models. And others are expected from the hand of Xiaomi and LG, in addition to the entry of Apple with the folding iPhone. As in the first generations, these formats need development, improvement of components such as hinges, and a greater number of applications that take advantage of them. Prices so far are extremely high, outside of mass consumption.


In chassis and finishes, there is still a difference in the different market segments. If the mid-range and entry-level tend to go for polycarbonate plastics, in the high-end we see premium materials such as aluminum, magnesium, and glass. The use of protective layers such as the one offered by the specialized firm Gorilla Glass are common and some smartphones add a greater degree of protection with resistance to water or splashes, bumps, and falls, although they do not prevent the use of screen protectors and covers. The industry offers rugged specialty terminals for professionals who work in environments that need them.


A trend that has been almost completely consolidated is the "all-screen" designs, where the bezels and frames are almost completely eliminated, opting to occupy the entire front of the terminal. It is an interesting design that allows you to expand the viewing area without having to increase the total size of the device, increasingly larger as we saw above.

Camera

The photographic and video capabilities of smartphones continue to improve. The versatility of these devices has sunk the sale of dedicated compact cameras and the truth is that (although they are still incomparable) their use is the majority and their benefits are highly valued by users.


The commitment to the multisensor to divide the tasks according to the shot to be made or as a complement to the main one; increasing their resolution; the addition of Artificial Intelligence functions and software improvement are the main trends. Here we must remember that a high number of sensors and megapixels does not ensure the best photographs and good optics and applications to take advantage of it are above the above.

Check out independent reviews because they may surprise you. The best smartphone camera in 2018 was mounted by Google on the Pixel 3. And with a single sensor. Other options to consider are the optical image stabilizer, autofocus, lens aperture, double LED flash, or video capacity with resolutions up to 4K.


In terms of design, the main camera tends to be mounted in specific frames increasingly larger to house the multiple sensors and integrated with the chassis at the rear. As for the headlamps for autofocuses, it seems that the industry is betting on getting rid of the holes in the screens once and for all. Some manufacturers employ flip-up camera designs on the chassis, although the general trend here is to include it below the screen.

Chipsets

There are no alternatives here. The ARM architecture completely monopolizes the main hardware engines for smartphones. Qualcomm is the world's leading supplier of third-party mobile chipsets and you will be able to see their designs in all market segments, while in the mid-range and entry-level Chinese manufacturer MediaTek also has a strong presence. The rest is distributed with manufacturers' own designs, Apple's SoCs for iPhones, Samsung's Exynos, or HiSilicon (Huawei) Kirin.

The trend here is for increased performance and the ability to integrate components. In addition to CPU and GPU performance to power tasks such as mobile gaming, chipsets are increasingly integrated, with expanded support for AI, augmented reality, DSP signal processing, and ISPs to support ever-increasing photographic sensors. Also important is the expansion of 5G chips beyond the high-end, both native and additional modem.

Memory and storage

The RAM memory capacity of current smartphones even exceeds the average in PCs and models with 12 and 16 Gbytes that have already been marketed. The installed average is below and you can find everything from the minimum admissible 1 GB in specific systems such as Android Go, going through 2, 4, 6, or 8 Gbytes. RAM is always preferable faster than capacity and manufacturers have to improve on optimization, but the trend is to include more and more. LPDDR 5s are on the way, but we don't know if we will see them at the end of the year in the most advanced smartphones.



In terms of storage capacity, we would place the minimum at 16-32 Gbytes, up to 256-512 Gbytes in the high-end range. The Tbyte brand is on the way and it will surely be Samsung who will debut it this year, while the new UFS 3.0 standard for storage solutions based on NAND Flash memory is an important advance that will allow achieving great performance.

The user's selection here is important considering that the RAM will not be able to be expanded in the future and the same in internal storage, since a large part of mobile phones no longer support microSD cards.

Connectivity

Expanding support for new 5G mobile networks from the high-end to the rest of the market by 'democratizing' their reach is a priority in the industry today and we have already seen solutions from Qualcomm and MediaTek for the mid-range. Although these networks have not yet spread to all regions nor have they deployed their full potential, there is no doubt that it is a bet for the future that the user must value.


Support for the Wi-Fi 6 wireless standard is another important element to consider due to its advantages over previous versions of the standard. It is already being deployed on new equipment. The same with Bluetooth 5.2, important because in mobile phones it is used to connect smartwatches and quantifying bracelets or the increasingly used wireless headphones once the classic audio jack has almost disappeared.


USB Type-C is the connector of the present and of the future in smartphones and is fully deployed in the mid-range and high-end terminals, while the short-range communication technology, NFC, has become optional, as well as the double -SIM, useful for some use cases. In the biometric authentication section, the most innovative thing is the fingerprint sensor under the screen, something that will end up spreading throughout the mid-range segment upwards.

Sound

A section perhaps less valued than the previous ones, but which is also worth knowing. The DAC (Digital-to-Analog Converter) converter chip is the key in the audio section and there can be a lot of difference in quality. Of course, having stereo speakers is a must to get started. Some of the best smartphones in this section include larger and more powerful speakers and design the inside of the terminals as a resonance chamber to reinforce the sound.


The use of dedicated external speakers, generally connected by Bluetooth, is another option when we are not on the move, in the office, or at home. There are many offers of all prices and qualities, without forgetting that we can also reproduce the audio from our smartphone in the new digital assistants or send it to high definition systems.


As for the headphone output, you know how things are. The typical audio jack is disappearing and the big manufacturers are eliminating the delivery of headphones so the final solution will be to have the best wireless headphones that your budget allows.

Autonomy

It is a pending account since smartphones have become increasingly powerful computers, with more functions and with all kinds of sensors that spend much, much more than the 'dumb' phones of the past. The issue is aggravated by the tendency to the extreme thinness of modern mobiles that prevents mounting batteries of greater capacity. Also by design (and for commercial reasons), manufacturers are betting on non-replaceable batteries complicating this section.


If autonomy is an important aspect for you, assess the capacity of the battery and that it can be replaced because, as we said, not all allow it. There are specialized models that include batteries with a higher capacity than the industry average that we could place between 3,500 and 4,000 mAh. Also, look for smartphones with fast recharging systems and additionally, those that allow wireless recharging that improves the comfort of the process without the need for wiring. Having a good own charger has gone from option to obligation since all manufacturers will follow in Apple's footsteps and will not include chargers in new mobile phones.

Operating systems

There is little to think about here because after the retirement of Windows Mobile and the failure of the Linux Mobile alternatives today there are no real alternatives beyond Android or iOS. Android sweeps the mobile market with estimated shares of over 87% and therefore almost all the offer is concentrated around the Google system.


Apple's iOS is second in market share (and last). As Apple does not license the operating system to other companies, you can only access this platform with the purchase of an iPhone. And a little more. Outside of the two major platforms, the offer is almost nil except for some Linux Mobile as a niche.


After Trump's blockade, Huawei is working on a Linux-based operating system called Harmony OS, but it needs more development, services, and applications that we do not know if they will have external support. It really is very difficult and not even a giant like Microsoft has been able to use Windows in its return to the mobile hardware market and its Surface Duo uses a tuned Android. Windows 10X could be an alternative for the future, but it remains to be seen.

Selection of smartphones in every price range

Since our last buying guide, all manufacturers have updated their catalog of smartphones and many of them are already on sale. The arrival of new models has caused large price cuts in previous generations. Don't forget them, because - generally - there hasn't been so much innovation and they may be worth it. Some are already announced for the next release, but not all are yet available.


To help you in the selection and as an example, because the offer is endless, we have divided the purchase by price levels in free sale starting with the high range and reaching terminals below the barrier of 100 euros, with a selection of some of those that seem most relevant to us from each range and trying to include models from all manufacturers. It is only a selection because the offer is very wide.
