Comparison Meizu M5s 32 GB vs Meizu M5 32 GB / 3 GB

The ratio of the screen area to the total front panel area of the phone. Simply put, this spec describes how much of the front panel is occupied by the screen; the rest is the bezels.

This indicator is given exclusively for smartphones with touch screens — it is for them that it is most relevant. The larger the percentage of the body is occupied by the screen, the thinner are the bezels, the neater the smartphone looks and the more convenient it is to work with it with one hand. As for specific numbers, the average values are 80 – 85 %, the higher values allow us to talk about a thin bezel, and more than 90 % — about a “bezel less” design.

Separately, we note that this parameter has nothing to do with the aspect ratio of the screen. The aspect ratio describes only the display itself — its proportions, the ratio between the larger and smaller side of the rectangle.

The most popular nowadays are chips from Qualcomm and MediaTek, CPUs from Unisoc are slightly less common. Qualcomm has several processors of each series, namely Snapdragon 765G, Snapdragon 778G, Snapdragon 7 Gen 1, Snapdragon 7+ Gen 2, Snapdragon 7 Gen 3, Snapdragon 865, Snapdragon 870, Snapdragon 888, Snapdragon 8 Gen 1, Snapdragon 8+ Gen 1, Snapdragon 8 Gen 2, Snapdragon 8 Gen 3. And Mediatek has a low cost series MediaTek Helio P and a line of advanced chipsets MediaTek Dimensity (Dimensity 1000, Dimensity 8000, Dimensity 9000).

Knowing the name of the CPU model installed in the smartphone, you can find detailed data on a particular CPU and evaluate its level and general capabilities. This is especially true in light of the fact that th...ese capabilities depend not only on the number of cores and clock speed, but also on the specific nuances of the design.

The clock frequency of the CPU that the device is equipped with. For multi-core processors, which are standard in modern smartphones, the frequency of each individual core is implied; and if the processor has cores with different frequencies (see "Number of cores") — usually, the maximum indicator is given.

In general, high performance smartphones have high frequency of the processor. However, note that this parameter itself is not directly related to the capabilities of the CPU: many other features of the chip affect the actual performance, and often a low cost solution with a higher clock speed turns out to be less performant than an expensive one, and at the same time, presumably, more "slow" processor. In addition, the overall performance of the system directly depends on a whole set of other factors — primarily the amount of RAM. Therefore, when evaluating a smartphone, it is worth focus not so much on the frequency of the processor, but on the general specs of the system and visual indicators like the results in tests (see below).

The model of the GPU used in the mobile phone.

This module is responsible for all tasks related to graphics; accordingly, its specs directly affect the efficiency of processing a particular picture. This is especially noticeable in the example of modern 3D games. Therefore, the presence of a powerful video adapter is especially important for gaming smartphones. And knowing the model of the GPU, you can find detailed data about it and evaluate its capabilities.

The largest volume of memory card with which the phone supports. For more information about the cards themselves, see "Memory Card Slot"; here we note that capacious cards often use advanced technologies that are not supported by all devices, and sometimes phones simply do not have enough power to process large amounts of data. Therefore, for the convenience of choosing in our catalog, the maximum supported volume is indicated.

In fact, there are cases when some devices may exceed the claimed characteristics. However, it is worth focusing on official data, because, if officially supported volume is exceeded, normal operation of the card is not guaranteed.

The test results are specified either by a younger model in a line or a particular model, made for a better understanding performance of phone models if you compare phones against these parameters. For example, the 128 GB model has test results, and the 256 GB model has no information on the network, and in both models you will see the same value that will give an understanding of the overall performance of the device. But if the editorial office has information for each model individually, then each model will have its test results filled out, and the model with bigger RAM will have bigger values.

The result shown by the device when passing the AnTuTu Benchmark performance test.

AnTuTu Benchmark is a comprehensive test designed specifically for mobile devices, primarily smartphones and tablets. It checks the efficiency of the processor, memory, graphics and I/O systems, thus providing a fairly visual impression of the capabilities of the system. The better the result, the more points are given at the end. And high-performance by AnTuTu rating are smartphones that score over 750K points

Like any benchmark, this test does not give absolute accuracy: the same device can show different results, usually with deviations within 5 – 7%. These deviations depend on many factors that are not directly related to the system — from the load of the device with third-party programs to the air temperature during testing. So, it is possible to speak about a significant difference between the two models only if the difference in their indicators goes beyond those 5 – 7%.

Communication standards supported by the mobile phone. In the modern world, several standards related to different generations are actively used: GSM, 3G, 4G (LTE)(with or without VoLTE), 5G (including fast mobile internet), CDMA. They vary in both specs and prevalence in different countries:

— GSM. The earliest of the communication standards found in modern telephones. Belongs to the second generation (2G). Allows you to make voice calls with acceptable sound quality, as well as transfer data at speeds up to 474 Kbps (using EDGE technology). Nowadays, GSM is considered completely obsolete, it has been almost universally replaced by more advanced standards of the next generations (3G, 4G, etc.). However, 2G support is found in most modern devices — not so much because of practical necessity, but because of technical features. The fact is that almost all communication standards that are relevant nowadays are add-ons over GSM, and modules for working with these standards are almost guaranteed to be compatible with GSM as well.

— 3G. In a broad sense, the 3G category (third generation communications) includes several standards. However, in the east european mobile phone market, this term refers specifically to the connection of the UMTS format. This standard is a development of GSM, such networks are often dep...loyed on the basis of ready-made networks of the 2nd generation and can also serve GSM phones without problems. Specifically, UMTS provides data transfer rates from 2 to 70 Mbps, depending on additional technologies implemented by a particular operator. This is already comparable to fixed Internet access; so, despite the spread of newer standards, 3G communication and phones for it are still quite popular — especially since such devices are compatible with 4G and 5G networks.

— 4G (LTE). Communication 4 generations based on the LTE standard; other 4G standards are not used in mobile phones. LTE is a further development of 3G (UMTS), deployed on the basis of the same technical base, but operates at higher speeds — up to 173 Mbps, which is comparable to a full-fledged broadband Internet connection. LTE networks are commercially operated in many countries of the world, but not in all; therefore, before buying a 4G-compatible phone, it's a good idea to check if it will be possible to use all its features in your area. Also note that voice calling over LTE ("VoLTE") is a separate topic; see below for details.

— 5G. Further, after 4G, the development of mobile communication standards. In the official specifications of this generation, a peak speed of 20 Gbps for reception and 10 Gbps for transmission, guaranteed speed (at high network load) of 100 and 50 Mb/s, respectively, as well as a number of solutions aimed at improving reliability and overall connection quality. A set of such solutions includes, in particular, multi-element antenna arrays (Massive MIMO) and beamforming technologies (Beamforming) at base stations, as well as the possibility of direct communication between subscriber devices. With all this, this standard allows to reduce energy consumption in comparison with its predecessors.
Separately, it is worth mentioning the rumors about the dangers of 5G communications for health. According to modern scientific data, such a connection does not pose a danger to the human body, and the rumors mentioned are conspiracy theories that are not supported by any weighty arguments.

— VoLTE. VoLTE is not a separate communication standard, but a technology used in devices with 4G LTE support (see above). The name of this feature stands for "Voice over LTE", which corresponds to its main specifics. The fact is that initially the LTE standard was created for data transmission (in other words, Internet access) and did not support classical voice communication in mobile networks; this format of operation is still found in some models of 4G phones. To remedy the situation, VoLTE technology was created. It allows you to use all the capabilities of 4th generation networks when talking on the phone, providing very clear and high-quality sound transmission. So if you plan to frequently use voice calls in LTE networks, you should pay attention to devices with this feature.

— CDMA. CDMA networks are known to users primarily by the activities of cell phone networks that provide the opportunity to receive a mobile phone with a direct city number. At one time, these networks competed with GSM and more advanced standards based on it, but as mobile communications developed and became cheaper, CDMA operators for the most part curtailed their activities in the voice communications market and switched to mobile Internet access services. It is worth noting here that the EV-DO Rev.A and Rev.B data transmission technologies available in CDMA networks are capable of providing connection speeds at the level of third-generation networks (up to 3.1 Mbps in the first case and up to 14.7 Mbps in the second), so in some places these services were promoted under the 3G label. However, this connection should not be confused with UMTS-based 3G (see above) — these are two fundamentally different standards that are incompatible with each other. Roughly speaking, if we are talking about 3G in a mobile phone, usually, we mean UMTS, but 3G modems more often use CDMA (EV-DO).

It is worth noting that the GSM, 3G and 4G standards (in that order) are, in fact, stages in the development of mobile networks of the same type. In fact, this means that a phone with support for a later standard, by definition, supports earlier ones — for example, a device with LTE is able to work with both GSM and 3G.

You also need to remember that different ranges can be used within the same standard, and not all of them can be supported in a mobile device. However phones officially sold in a certain country are usually optimized for local networks, and there should be no problems with them. But if the device is planned to be imported from another country, and it was not intended for the local market, it makes sense to first clarify the compatibility by bands. Otherwise, a situation may arise when the device simply “does not see” the network, although formally it will be compatible with a certain communication standard.

Additional features and capabilities of the device.

In modern mobile phones (especially smartphones) a very extensive amount of additional features can be provided. These can be both already familiar features, many of which are directly related to the original purpose of the device, as well as fairly new and/or unusual ones. The first category includes an emergency call button(often found on phones for the elderly), noise cancellation, FM receiver, notification light, a simple flashlight and a light sensor. The second category includes a face and fingerprint scanner (the latter can be located on the back cover, side panel, front and even right under the screen), gyroscope, advanced full-fledged flashlight, stereo sound, 3D surround sound, Hi-Res Audio, augmented reality support and...even such exotics as a barometer. Here is a more detailed description of each of these options:

— Face scanner (FaceID). A special technology for recognizing the user's face — not just by photographing, but by building a three-dimensional model of the face based on data from a special module on the front panel. This technology is constantly being improved, nowadays it is able to take into account the change of hairstyles and facial hair, the presence of glasses, makeup, etc. At the same time, the recognition of twins and children's faces still remains weak points (they have fewer individual features than adults ). The main use of a face scanner is authentication when unlocking a smartphone, entering applications, making payments, etc. At the same time, other, more original use cases are possible. For example, in some applications, the face scanner reads the user's facial expressions, and then this facial expression is repeated by an emoji on the phone screen.

— Fingerprint scanner. Fingerprint reader. It is mainly used for user authorization - for example, when unlocking the device, entering certain applications or accounts, confirming payments, etc. As for placement options, fingerprint scanners are increasingly moving from the back cover of the device to the surface of the side power / unlock button - to You can touch the sensor on the side with your thumb without releasing the smartphone from your hands and practically without changing your grip. Some time ago, sensors on the front of the case were quite popular - in particular, thanks to Apple, which was the first to tightly implement fingerprint recognition in its gadgets. However, such placement inevitably increases the size of the bottom frame, so the front fingerprint scanner is rare in modern smartphones. A good alternative to it is scanners right on the screen (more precisely, under the display matrix), which do not take up extra space on the front panel.

— Google AR Core. Smartphone support for Google AR Core augmented reality (AR) technology. This technology is used to work with AR in Android smartphones. Read more about augmented reality and special technologies below.

— Apple AR Kit. Smartphone support for augmented reality (AR) technology Apple AR Kit. This technology is used to work with AR in Apple smartphones running on iOS. Read more about augmented reality and special technologies below.

— Support for special augmented reality technologies. The general idea of augmented reality (AR) is to add certain additional elements to the image of the real world that is visible on the screen of the device, "embedded" in the real world and looking like a part of it. One of the most famous examples of AR is the game Pokemon Go, where the player had to use the camera to look for virtual Pokemon in a real area. Other applications are navigation (displaying a "guide line" directly on the smartphone screen over the image from the camera), interior design (the ability to virtually fit one or another object into an existing environment), car repair (highlighting key details, "X-ray vision") etc. However, in this case, we are talking not just about the ability to work with AR applications, but about support for special augmented reality technologies — usually Google AR Core or Apple AR Kit. The peculiarity of these technologies is that they expand the possibilities available to both users and software developers. So, users get a more extensive set of AR applications, with more advanced abilities; and the developers of such applications can be not only large companies, but almost everyone, including individual specialists.

— Stereo sound. The ability to play full stereo sound through your phone's own speakers, without external audio devices. There must be at least two speakers for this task. This complicates the design and increases its cost, but it has a positive effect on the sound quality: the sound is more expressive and detailed than when using a single speaker, it has a volume effect, as well as a higher volume.

– 3D surround sound. The mechanics of spatial surround sound with localization of sound sources in three-dimensional space allows you to deeply immerse yourself in the atmosphere of films, enjoy listening to audio tracks, or completely immerse yourself in mobile gameplay. Algorithms for implementing 3D sound in smartphones differ in terms of software and hardware support, but they are all aimed at achieving the effect of realistic sound stage. Note that support for 3D surround sound can mean both commonly used technologies such as Dolby Atmos or DTS:X Ultra, as well as proprietary solutions from individual audio brands that have a hand in the sound subsystem of a mobile device (AKG, JBL, Harman, Huawei / Honor Histen, etc.).

– Hi-Res Audio. Mobile device support for high-resolution audio Hi-Res Audio - a digital signal with parameters from 96 kHz / 24 bits. Audio tracks in this format sound as close as possible to the original ideas of the authors of the compositions. The result is a sound that is as close as possible to what was recorded in the studio.

— FM receiver. Built-in module for receiving radio stations broadcasting in the FM band. Some devices also support other bands, but FM is the most popular nowadays (due to the ability to transmit stereo sound), it is in it that music radio stations usually broadcast. Note that some devices for reliable reception may require the connection of wired headphones — their cable plays the role of an external antenna.

— Notification indicator. Physically separate light beacon, pulsating or being constantly lighted up in response to incoming notifications of missed calls and received messages (including the ones from instant messengers and social network clients). Also, the indicator light usually signals a low remaining battery level and lights up during the battery recharging. The implementation of the notification indicator can be different: for some phones it is single-colour, for others it has colour coding of signals, flexibly adjustable for certain events through the settings menu. The light beacon allows you to visually comprehend the presence of incoming notifications without having to turn on the smartphone screen.

— Emergency call button. A separate button designed for use in critical situations. The specific features of such a button may be different, depending on the model: sending “alarming” SMS to selected numbers, automatically receiving calls from these numbers or calling them in turn, turning on the siren, etc. Anyway, the “emergency” button is usually clearly visible, and its presence is especially useful if the phone is used by an elderly person (in fact, in specialized devices designed for elderly, this button is almost mandatory).

— Noise suppression. An electronic filter that cleans the user's voice from extraneous noise (sounds of the street, the rumble of the wind in the microphone grille, etc.). Thus, the person at the other end of the line hears only the voice, with virtually no extra sounds. Of course, no noise reduction system is perfect; however, in most cases, this feature significantly improves the quality of the speech transmitted by the phone to the other person.

— Gyroscope. A device that tracks the rotation of a mobile phone in space. Modern gyroscopes, usually, work on all three axes and are able to recognize both the angle and the rate of turn; in addition, this feature almost necessarily means the presence of an accelerometer, which allows (among other things) to detect tremors and sharp movements of the device. This provides advanced control options — in particular, gyroscopes are indispensable when working with augmented reality (see above) or when using VR glasses into which a smartphone is installed.

— Flashlight. The ability to use the phone as a flashlight. We emphasize that in this case we are usually talking about the simplest version of a flashlight — when this feature is performed by the flash of the main camera, which is turned on through the software settings. More advanced lamps are indicated in the specs as a "full-fledged flashlight" (see below).

— Full-fledged flashlight. The presence of an advanced flashlight in the phone — more powerful than the usual one (see above). The specific design and capabilities of such a flashlight may be different. So, in some devices, a separate LED (or a set of LEDs) is provided on the upper end, and this light source is used only as a flashlight. In others (mainly smartphones), we are talking about a special design of the flash: it consists of several LEDs, and only a part of them is usually used to illuminate when shooting, and all at once to work in flashlight mode. And the additional features of such a light source may include a laser pointer, beam focus, brightness control, etc. Anyway, most models with this feature are rugged devices with increased resistance to dust, moisture and shock (however, there are exceptions).

— Light sensor. A sensor that monitors the level of ambient light. It is mainly used to automatically adjust the brightness of the screen: in bright ambient light, it increases so that the image remains visible, and in twilight and darkness it decreases, which saves battery power and reduces eye fatigue.

— Barometer. Sensor for measuring atmospheric pressure. By itself, the barometer only determines this pressure at the current time, but the methods of using such data may be different, depending on the software installed on the phone. For example, some navigation applications can determine the elevation difference between individual points on the ground by the difference in atmospheric pressure at these points; and in weather programs, barometer data can improve the accuracy of weather forecasts. Also, this feature will be useful for weather-sensitive people: it signals a change in the weather, allowing you to more accurately determine the cause of ailments and take measures to eliminate them.
