Comparison Vivo V17 128 GB vs Vivo V17 Neo 128 GB

The parameter determines the overall performance of the smartphone: the more RAM, the faster the device works and the better it copes with an abundance of tasks and / or resource-intensive applications (ceteris paribus). This is even more true in light of the fact that large amounts of "RAM" are usually combined with powerful advanced processors. However, only devices with identical operating systems can be directly compared with each other, and in the case of Android, with the same versions and editions of this OS (for more on all this, see "Operating system"). This is due to the fact that different operating systems and even different versions of the same OS can differ markedly in terms of RAM requirements. For example, iOS, thanks to good optimization for specific devices, is able to work efficiently with 3 GB of RAM. For modern versions of Android in the regular edition (not Go Edition), the mentioned 3 GB is actually the required minimum. Under such an OS, it is better to have at least 4 GB or 6 GB of RAM. In high-end devices with powerful electronic "stuffing" you can also find more impressive numbers - 8 GB or even 12 GB or more.

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 a device when undergoing a performance test (benchmark) in AnTuTu Benchmark.

AnTuTu Benchmark is a comprehensive test designed specifically for mobile devices, primarily smartphones and tablets. It evaluates the efficiency of the processor, memory, graphics, and input/output systems, providing a clear impression of the system's capabilities. The higher the performance, the more points are awarded. Smartphones that score over 1.5M points are considered high-performance according to the AnTuTu ranking.

Like any benchmark, this test does not provide absolute precision: the same device can show different results, usually with deviations within 5-7%. These deviations depend on various factors unrelated to the system itself, such as the device's load from third-party programs and the ambient temperature during testing. Therefore, significant differences between two models can only be noted when the gap in their scores exceeds this margin of error.

The result shown by a device when undergoing a performance test (benchmark) in Geekbench.

Geekbench is a specialized benchmark designed for processors. Since version 4.0, it also includes tests for graphics processors, and by the end of 2019, version 5 of the benchmark was released. Typically, the specifications for portable gadgets include data specifically for the CPU. During testing, Geekbench simulates workloads that occur during real-world tasks, evaluating both single-core performance and the efficiency of multi-core operations. This provides a solid overview of the processor's capabilities in everyday use. Additionally, Geekbench is cross-platform, allowing for comparisons between the CPUs of different devices (smartphones, tablets, laptops, PCs). In reference materials, only the multi-core test results for the processor are usually provided.

The number of individual lenses provided in the module of the main (rear) camera of the device. Specified only if there are several lenses. At the same time, each «eye» has its own sensor and, in fact, is a separate camera; however, they can be used in conjunction, forming one image from data from several lenses, or mutually complementing each other's capabilities. As an illustration of the second case, the following example can be given: when using the zoom, the smartphone can automatically switch from the main optics to the telephoto lens when the magnification selected by the user exceeds a certain threshold.

The simplest version of the main module with several lenses is a dual camera, however, devices with 3 or more rear cameras are becoming more common (in some models, the number of lenses can reach six). Anyway, these cameras usually differ in specifications and perform different functions. So, an ordinary colour camera can be supplemented with a lens for black-and-white shooting, which improves contrast; in some models, lenses with different focal lengths allow you to choose the optimal viewing angle for certain conditions; information from an auxiliary lens (see below) is usually used to adjust the depth of focus on an already finished shot, etc. These details should be clarified separately, but anyway, several lenses mean more shooting options.

Specifications of the main lens of the rear camera installed in the phone. In models with several lenses (see “Number of lenses”), the main one is responsible for basic shooting capabilities and does not have a pronounced specialization (wide-angle, telephoto, etc.). Four main parameters can be indicated here: resolution, aperture ( high aperture optics are quite common), focal length, additional sensor data.

Resolution(in megapixels, MP)
Resolution of the sensor used for the main lens. Budget options are equipped with a module 8 MP and below, many models have 12 MP camera / 13 MP, also recently a trend towards increasing megapixels has been popular. Often in smartphones you can find the main photomodule at 48 MP, 50 MP< /a>, 64 MP and even 108 MP, 200 MP.

The maximum resolution of the resulting image directly depends on the resolution of the sensor; and the high resolution of the "picture", in turn, allows you to better display fine details. On the other hand, an increase in the number of megapixels in itself can lead to a deterioration in the overall image quality - due to the smaller size of each individual pixel..., the noise level increases. As a result, the direct resolution of the camera has little effect on the quality of the shooting - more depends on the physical size of the matrix, the features of the optics and various design tricks used by the manufacturer.

Aperture
Aperture describes the ability of a lens to transmit light. It is written as a fractional number, for example f/1.9. Moreover, the larger the number in the denominator, the lower the aperture ratio, the less light passes through the optics, all other things being equal. For example, an f/2.6 lens will be “darker” than f/1.9.

High aperture gives the camera a number of advantages. First, it improves the quality of shooting in low light. Secondly, it's possible to shoot at low shutter speeds, minimizing the effect of "stirring" and blurring of moving objects in the frame. Thirdly, with fast optics it is easier to achieve a beautiful background blur ("bokeh") — for example, when shooting portraits.

Focal length(in millimetres)
The focal length is a distance between the sensor and the centre of the lens (focused to infinity), at which the most clear image is obtained on the matrix. However, for smartphones, the specifications indicate not the actual, but the so-called equivalent focal length — a conditional indicator recalculated using special formulas. This indicator can be used to evaluate and compare cameras with different sensor sizes (the actual focal length cannot be used for this, since with a different sensor size the same real focal length will correspond to different viewing angles). (It is also worth saying that the equivalent focal length can be noticeably larger than the thickness of the case — there is nothing unusual in this, since this is a conditional, and not a real indicator).

Anyway, the field of view and the degree of magnification directly depend on the equivalent focal length: a larger focal length gives a smaller field of view and a larger size of individual objects that fall into the frame, and a decrease in this distance, in turn, allows you to cover more space. In most modern smartphones, the focal length of the main camera ranges from 13 to 35 mm; if compared with the optics of traditional cameras, then lenses with equivalent focal length up to 25 mm can be attributed to wide-angle lenses, more than 25 mm — to universal models “with a bias towards wide-angle shooting”. Such values are chosen due the fact that smartphones are often used for shooting in cramped conditions, when a fairly large space needs to fit into the frame at a small distance. Enlargement of the picture, if necessary, is most often carried out digitally — due to the reserve of megapixels on the sensor; but there are also models with optical zoom (see below) — for them, not one value is given, but the entire working range of the equivalent focal length (recall, optical zoom is carried out by changing the focal length).

Field of view(in degrees). It characterizes the size of the area covered by the lens, as well as the size of individual objects "seen" by the camera. The larger this field, the more of the scene gets into the frame, but the smaller the individual objects in the image are. The field of view is directly related to the focal length (see above): increasing this distance narrows the field of view of the lens, and vice versa.

Note that this parameter is generally considered important for professional use of the camera rather than for amateur photography. Therefore, viewing angle data is given mainly for smartphones equipped with advanced cameras — including in order to emphasize the high class of cameras. As for specific values, for the main lens they usually are in the range from 70° to 82° — this corresponds to the general specifics of such optics (universal shooting with an emphasis on general scenes and extensive coverage at short distances).

Additional Sensor Data
Additional information regarding the sensor installed in the main lens. This item can specify both the size (in inches) and the sensor model, and sometimes both parameters at once. Anyway, such data is provided only if the device is equipped with a high-end sensor. With the model, everything is quite simple: knowing the name of the sensor, you can find detailed data on it. The size is worth considering a little more.

The size of the sensor is traditionally indicated in fractional parts of an inch — accordingly, for example, a 1/2.3" sensor will be larger than 1/2.6". Larger sensors are considered more advanced, as they provide better image quality at the same resolution. The logic here is simple - due to the large sensor area, each individual pixel is also larger and gets more light, which improves sensitivity and reduces noise. Of course, the actual image quality will also depend on a number of other parameters, but in general, a larger sensor size usually means a more advanced camera. In advanced photo flagships, you can find matrices with a physical size of 1”, which is comparable to image sensors used in top compact cameras with fixed lenses.

The presence of a macro lens in a smartphone. In some models, this feature is performed by a separate specialized lens, in others — by the lens of the main camera, which operates in a special mode.

Macro photography, for which such lenses are used, is a special mode that allows you to get very large and detailed images of miniature objects (for example, dew drops or a small insect). This mode is most often used as an artistic tool, but it can also be useful for other purposes, such as scientific ones. And the presence of a full-fledged macro lens means that the smartphone has quite advanced capabilities for such shooting. At the same time, the main camera is considered a macro lens only if it is capable of performing macro photography from a distance of 3 cm or less.

Wired connectors provided in the phone design.

This section usually specifies the type of universal connector (most often USB-C) and the presence of a mini-jack (3.5 mm) socket (some devices are without this socket). Additionally, this section may indicate the USB-C port interface up to the high-speed third version (USB-C v 3), the location of the 3.5 mm connector (headphone output), and the presence of additional ports for more specific purposes.

Universal connectors are used primarily for battery charging, connecting various accessories to the phone, and connecting the phone itself to a computer via cable; the 3.5 mm port is mainly intended for headphones and other audio accessories, although other usage formats are possible. Here is a more detailed description of different types of connectors:

— USB-C. A kind of successor to microUSB, increasingly used in mobile devices. USB-C differs from its predecessor primarily by slightly larger size and convenient reversible design: thanks to this, it doesn't matter which way you insert the plug. In addition, this interface allows for more advanced functions than microUSB – in particular, some fast charging technologies were initially created specifically for USB-C. It is also worth noting that the characteristics may specify the USB standard supported by this type of...connector. Nowadays, the following options are found:

• USB-C 5Gbps. Standard, previously known as USB 3.0 and USB 3.2 gen1. Provides data transfer speeds up to 4.8 Gbps.
• USB-C 10Gbps. Modern name for the standard previously called USB 3.1, then USB 3.2 gen2. The connection speed through this interface can reach 10 Gbps.
• USB-C 20Gbps. Standard (formerly known as USB 3.2), providing twice the speed of USB-C 10Gbps – that is, up to 20 Gbps.

— DisplayPort Alt Mode. A feature that allows video signal transmission through the USB-C port. This means that a smartphone can be connected to an external display (monitor, TV, etc.) directly through a USB-C cable, without the need for additional adapters or converters. DisplayPort Alt Mode requires support both on the smartphone and the connected device (monitor, TV), and a suitable USB-C cable capable of transmitting video.

— microUSB. A universal connector that was extremely widely used in portable devices at one time (with the exception of Apple technology). It is less convenient and technically advanced than USB-C, so it is gradually losing popularity; nevertheless, many devices with microUSB are still available for sale.

— Lightning. A proprietary connector by Apple, used exclusively in iPhones among smartphones. It has a reversible design, allowing the plug to be connected either side up. In modern iPhones, it is used both as a universal connector and for headphones connection (in 2016, Apple removed the 3.5 mm audio output from these devices).

— Proprietary connector. Some universal connector that does not fall into the described types above. Such equipment is extremely rare nowadays—standard interfaces are more convenient and universal, as they allow the use of not only "native" accessories but also solutions from third-party manufacturers.

— Magnetic connector. A connector where a permanent magnet is used to hold the cable instead of the standard "plug-socket" system. Such devices are primarily used in water-protected devices (see "Water Resistance"), and most often for battery charging and in addition to standard universal connectors (usually microUSB or USB-C). The main convenience of a magnetic connector is that water protection does not require plugs. Thus, firstly, connecting and disconnecting the charger is simplified, and secondly, wear on the plugs of standard ports is minimized—they do not need to be opened and closed every time for charging. However, a magnetic connector only fits a special "native" cable; however, in case of loss or breakage of this cable, there may be a provision for charging in the usual way through a traditional universal connector.

— Mini-jack (3.5 mm). A connector mainly used for connecting wired headphones and other audio devices (e.g., portable speakers). Such a connection is extremely popular among audio accessories (not only of mobile purpose); thus, finding headphones, a headset, or speakers for this connector is usually not a problem. Additionally, the 3.5 mm socket may be used for more specific tasks, such as connecting a card reader or exchanging data with wearable fitness sensors and other specific equipment. However, these possibilities are rarely used and require the installation of special applications, whereas headphone connection is the primary function of such a connector, available by default. Therefore, the mini-jack connector is often referred to as a "headphone output."

— Location of the headphone output. The described 3.5 mm output in modern phones can be located on the top, bottom, or side edge of the device. However, the latter option is generally less convenient than the first two and is therefore rare. The choice on this indicator primarily depends on how exactly you plan to carry the phone and from which side it will be most convenient to connect headphones; for different situations, optimal options will also differ.

Because manufacturers claim a very conditional battery life (in an unknown mode, with unstated brightness indicators and phone settings) in the specs of their gadgets, which is more marketing and is not confirmed in reality, we decided to display a more accurate picture. The operating time indicated in this paragraph is the result of the PCMark Work 2.0 Battery Life benchmark, which evaluates energy efficiency in five work formats: web surfing, video viewing/editing, photo editing, working with text documents and working with data (extracting them from different file formats, building charts). These are the main tasks that a smartphone is supposed to perform in everyday life. And thanks to this testing format, the results very accurately correspond to the actual battery life of the gadget with active use during the day.
