    The Galaxy A51 is one of Samsung's most popular and popular phones of 2020, and its popularity continues after nearly a year and a half of its presence in the market. In March 2021, the family introduced a new dual in the A52 series, which differed significantly from previous members of the Samsung A5x series. In addition to changes in design and appearance, the A52 series also comes with significant differences in terms of processor, main camera, battery life and charger, which at a glance makes it a prominent update for this family. In the continuation of this article, by comparing the Galaxy A51 and Galaxy A52 face to face, we have mentioned their differences with each other in different fields.

     Comparison of Galaxy A51 and A52 - a difference beyond two generations Design and body shape

    Samsung has made a noticeable change in the design language of the device in the A52 and introduced a new form for this class, which is why The face is also repeated in the A72. In this new design, despite the fact that the conditions are very much in the upper part of the device and the same small margins around the screen and the upper central notch are used, but in the back part, we face several changes.

    The first obvious point in this part is the abandonment of the sleek body of the A51, which with Its existence created beautiful effects by moving in the light, but it also absorbed dirt and fingerprints in a fraction of a second, and did not have an excellent performance against scratches over time. In the A52, despite the repeated use of plastic in this part, matte and fingerprint resistant material is used, which gives a completely modern look to this phone.

    Another new point in the design of the A52 is that the side edges of the back cover are not curved, which makes this model thicker than Samsung's past experience shows. This design, of course, includes the same size of the perimeter bar, which creates an eye-catching combination due to its same color with the back.

    Another important point in this section is to consider the IP67 resistance standard for the A52, which has no place in the A51, and thus not just a particular concern. When using the A52, it does not exist in the rain, but it can practically be immersed in clear water for a depth of 1 meter for 30 minutes. This option has not had a place in this series until today. Dimensions and sizes

    Due to the uniform size of the display in both models of this competition, comparing them in terms of dimensions and weight seems interesting, but from the beginning, due to the larger volume of the battery, you can expect more thickness and weight. Had from A52; This is what happens in practice, but the differences between the two models do not end there. The length and width of the A52 are 159.9 and 75.1 mm, respectively, which are both significantly larger than the A51 with the length and width of 158.5 and 73.6, respectively.

     Comparison of Galaxy A51 and A52 - a difference beyond two generations

    In terms of thickness, this difference continues as mentioned and A52 with a thickness of 8.4 mm, half a millimeter from Its counterpart is bigger. This thickness is not sharpened because the edges are not curved and looks a little more in the hand. Despite the difference in thickness between the two models, neither of them can still be considered too large and unacceptable.

    The power and volume buttons on the right side of both phones are almost at the same height, and in both cases relatively easy access to the power button and There is a low volume, but to press the high volume, you need a second hand or move the phone in hand.

    https://mobiletony.com Comparison of Galaxy A51 and A52 - a difference beyond two generations

    A52 with weight 189 The gram is almost 17 grams heavier than its rival, but this difference seems quite negligible at a glance at the larger battery of the device. Screen

    Both phones in this competition feature a 6.5-inch Super AMOLED display with a resolution of 1080 x 2400 pixels, with a circle approximately 3 mm in diameter for the selfie camera. The similarities between the two screens, however, end here, and more subtle differences between them become apparent.

    https://mobiletony.com Comparison of Galaxy A51 and A52 - a difference beyond two generations

    The first difference between these There are two panels in their upgrade rate, which is a significant difference (at least from the point of view of many users); The A51 display has a refresh rate of 60 Hz, which means that the image of this panel is updated 60 times per second. This figure reaches 90 Hz on the A52, making it a much smoother experience when scrolling through menus, scrolling through social media, and playing games that fit the technology.

    https://mobiletony.com Comparison of Galaxy A51 and A52 - a difference beyond two generations

    Of course, it has a negative effect on battery consumption, but as we will see later in the battery section, this effect will not be very significant and colorful.

    Another difference between the two panels is their brightness, in which case the A52 performs much better than last year's A51 with a maximum brightness of 800 nits. The contents of both panels still retain their readability by activating auto-brightness in direct sunlight, but in a face-to-face comparison, the A52 performs better. In terms of color quality, if we set the screens to Natural, we will get an acceptable result in both phones, and there is no big difference between them.

    https://mobiletony.com Comparison of Galaxy A51 and A52 - a difference beyond two generations

    Angle of View and Contrast Also, there is no significant difference between these two phones, and in both cases, we come across quite plausible examples.

    https://mobiletony.com Comparison of Galaxy A51 and A52 - a difference beyond two generations

    margins around the screen in The A51 and A52 are not much different, with nearly 4mm at the bottom and around 2mm at the sides and top, although some small differences in this area have led to a slight difference in length and width between the two handsets.

    https://mobiletony.com Comparison of Galaxy A51 and A52 - a difference beyond two generations

    https://mobiletony.com Comparison of Galaxy A51 and A52 - a difference beyond two generations Samsung fingerprint sensor

    Samsung on both A51 and A52 due to OLED screen display from sensor It uses optical fingerprint inside the panel, which is a common type of light, so no significant difference is expected between them in terms of speed and accuracy. In both cases, the user is warned not to use protective covers and glasses on the screen before the finger recognition process begins; Covers that, if not standard, will be a significant obstacle to the operation of this sensor, both during detection and when unlocking. On the screen of both phones, of course, a plastic screen protector has already been drawn, which is not a problem in this regard until it is on the panel.

    https://mobiletony.com Comparison of Galaxy A51 and A52 - a difference beyond two generations

    The two sensors can be considered identical in practice, and both require a little over 1 second to unlock (when the screen is off). Although this time is longer than normal capacitive sensors off the screen, it often does not seem too slow (at least indoors) or does not seem annoying.

    Selfie camera

    The selfie camera of the two phones on paper is different In both cases, a 32-megapixel sample without autofocus with f/2.2 was used. The trump card of this camera compared to some similar examples is its support for HDR, which will help the user in environments with intense backlight.

    https://mobiletony.com Comparison of Galaxy A51 and A52 - a difference beyond two generations

    This camera is like another High-resolution cameras have a default resolution different from the original resolution (32-megapixel), and in the closed-frame form, it is 8-megapixel, and when opened, it is 12-megapixel. The closed or open form of the frame in this camera is determined by a slider next to the shutter button, and in closed and open mode can be photographed with resolutions of 20.7 and 32 megapixels (of course without HDR).

    Photos The selfie camera in these two phones has almost the same level of detail and color accuracy in the same conditions, and although the lack of autofocus requires the proper distance of the face from the camera (something close to one hand), but if you consider the optimal distance , The end result in both is almost the same and comparable. Both the A51 and A52 selfie cameras support video capture at a maximum resolution of 4K/30fps, and there is no difference.

    Main Cameras

    One of the most important differences between the two phones is the rear cameras, specifically the main cameras, which make them stand out from the camera. The main camera on the A51 is a 48-megapixel autofocus with an aperture of f/2.0, which was similarly used on paper in the A50s. In the A52 family, however, not only is a larger sensor with a higher resolution of 64 megapixels used, but also the aperture of the lens has been widened to f/1.8. These two, of course, are not the only changes to this camera, and for the first time in this family, a valuable OIS option or optical image stabilization has been added to the list of features of the A52 main camera. OIS on the A52 Although only available in full HD resolution at 30 frames per second, its presence is a big advantage for the A52, especially when shooting video in low light environments.

    https://mobiletony.com Comparison of Galaxy A51 and A52 - a difference beyond two generations

    Two other cameras included A 12-megapixel ultra-wide unit with f/2.2 and 123-degree field of view and a 5-megapixel macro camera with f/2.4) for close-up shooting (no different than before, and none of them are equipped with autofocus. Finally, the 5-sensor. The megapixel depth of field is also shared between the A52 and A51.

    With the A51 upgrade to Android 11 and OneUI 3.0, the camera interface between the phones in this competition looks the same, so the differences have to be made in the field and in Search for image quality.

    The A52's main camera produces images in full daylight with more color heat and higher detail, as seen in the two images below and their actual size slices.

    This condition is also repeated in the following subject and in terms of Clear colors and details can speak to the better condition of the A52.

    Auto HDR option on the main camera of both phones It is assumed to be active, and although in some cases the scales weigh heavily toward the A52, we can be satisfied with the end result of both.

    Color saturation percentage in A51 main camera is quite more than It rivals, and while we may come across more attractive colors from the user's point of view, they offer lower accuracy compared to the A52 and look farther from the real colors.

    from the ultraviolet cameras of these two phones according to The same resolution and aperture of f/2.2 we expect a close result, but in practice the A51 still retains its tendency for high color saturation and creates an image with less light, which is practically to the detriment of image detail.

    Rolling shutter problem and abnormal stretching of moving subjects in ultraviolet cameras still in any Two standing phones Of course, there is no expectation for a complete solution in this price range.

    The condition of the macro camera was similar to what we saw in the UltraVide camera, and although the resolution and aperture of these lenses are the same, expect to see similar images in the mind, but in practice open with more detail and more natural colors and even more light in the A52 we will be.

    A52 at night It offers superiority over its opponent and even before activating Night mode, its better result can be seen. On both phones, by activating Night mode, the default resolution of the main camera decreases by closing one step, reaching 12 megapixels on the A52 and 8 megapixels on the A51. On the A51, the resolution of the ultraviolet camera also decreases from 12 to 8 megapixels, but on the A52, the resolution of the ultraviolet camera does not change when Night mode‌ is active.

    The night mode difference between the two phones in the ultraviolet camera has continued and still The balance pan weighs well towards the A52 in Night Fashion.

    A51 And the A52 naturally offers the ability to take photos at maximum resolution, ie 48 and 64 megapixels, respectively, which capture a lot of detail in full and sufficient light, allowing for more cropping and zooming. Using the camera's full resolution, but apart from creating a much larger file, in low light environments produces a poorer result in terms of detail and overall image quality compared to the default resolution (12 megapixels on the A51 and 16 megapixels on the A52).

    1080p/30fps videos The main cameras of both phones are not much different in terms of audio and video bitrate, but in practice due to the presence of OIS or optical image stabilization in the A52 and its absence in the A51 on the one hand and the algorithm Different image processing in these two cameras, on the other hand, we encounter completely different results in them; Where more vivid colors and details are seen in the A52 videos and in terms of contrast, the A52 should be considered the top choice in this competition. The presence of OIS leads to smoother motion, and in the A51, although the digital image stabilization has helped stabilize the image to some extent, it is practically in a lower position than the A51.

    The A51 does not have 1080p/60fps resolution, and the A52, despite the fact that this option is not available, has an amazing result due to the lack of OIS. We do not wash. At 4K/30fps, the main camera of both phones is more detailed, and the issue of higher color quality and contrast in the A52 is repeated here.

    The A52's Ultraviolet camera captures much higher light and vivid colors at 1080p/30fps, and scores high in terms of image stabilization. 1080p/30fps image stabilization works well on the A51 and A52 Ultraviolet Cameras. These cameras also support 4K video capture at 30 frames per second, the output of which is lower in terms of image stabilization.

    Speakers and sound quality

    Another new point in the A52's structure is the presence of two stereo speakers in this model, which seems to be an interesting change compared to the A51 with only one speaker. One of the speakers is usually located at the bottom of the phone, next to the USB port, and the other should be searched inside the call speaker at the top of the screen. This combination provides users with an immersive sound, especially when holding the phone horizontally (which usually occurs in gaming and multimedia applications), which has not had a place in the cheaper, more expensive Samsung mid-range phones to date.

    https://mobiletony.com Comparison of Galaxy A51 and A52 - a difference beyond two generations The power of the A52 is mediocre, which, while playing from two outputs at the top and bottom of the device, is more appealing than before, but still does not leave its mediocre position. Compared to the A51, the sound output from the A52 speakers is much warmer and clearer, but the main output at the bottom is somewhat less powerful at high frequencies (lower sounds), which is why the A51 looks a bit louder with less bass, although the loudness difference between the two phones It is not very obvious and big.

    https://mobiletony.com Comparison of Galaxy A51 and A52 - a difference beyond two generations

     https://mobiletony.com Comparison of Galaxy A51 and A52 - a difference beyond two generations

    Both phones support DolbyAtmos, except that on the A51, activating this option for music and games requires a headset connection, but on the A52, this feature can also be accessed when playing audio from the device's speakers. The ability to adjust the equalizer is another common option between the two models.

    https://mobiletony.com Comparison of Galaxy A51 and A52 - a difference beyond two generations Battery and Charger Another important difference that separates the A52 from its rival is the issue of battery capacity and durability, where the A52 now uses a 4,500 mAh battery with a 12.5% ​​increase in battery capacity. According to Samsung, this battery will last up to 32 hours in 4G talk time, up to 120 hours in music playback and up to 20 hours in video playback. If we compare it with 23 hours of talk time, 86 hours of music playback and 19 hours of video playback in A51 The A52 can be viewed clearly.

    https://mobiletony.com Comparison of Galaxy A51 and A52 - a difference beyond two generations

    The superiority of the A52 family in this area, in addition to the higher capacity of the battery, is not unrelated to its newer processors, and the use of lower-consumption and newer 8nm processors has created better conditions for these two models.

    To find out the difference between the two models in practice, we went to the Work 2.0 test from the PCMark suite, which is a comprehensive scenario of using a phone consisting of web browsing, video editing, opening, editing and saving a text document. Photo editing and things like that last from 100% of the battery charge to below 20%. We perform this test by disabling auto brightness and 50% screen brightness. The A51 lasted almost 11 hours (exactly 10 hours and 57 minutes) in this test, while setting the A52 to a refresh rate of 60 Hz (to compare the numbers between the two phones) scored a much better 13 hours. Registered under his own name. It is also important to note that by activating the 90Hz refresh rate in this test, the result obtained naturally decreases to a certain extent, but it is still somewhat better than the A51.

    https://mobiletony.com Comparison of Galaxy A51 and A52 - a difference beyond two generations

    Charger with both phones is 15 watts but The A52 also supports faster 25-watt charging, which the charger would naturally have to provide separately. The charging speed of both phones is not much different from standard 15-watt chargers, and it takes about 100 to 110 minutes to fully charge the battery. The A52, meanwhile, is slightly faster, charging 64% of its battery capacity, for example, after an hour while the A51 reaches 59% charge.

    With a 25-watt charger, naturally at a much higher speed We find that it will save users a lot of time. This charger, of course, is not usable for the A51, and in this regard, another positive point should be credited to the A52 account. CPU and memory

    Apart from all the changes mentioned in the structure of the A52 compared to last year's A51, a change seems to be more important than anything else, where the 10-nanometer Exynos 9611 processor in the A51 not only increases processing power The A51 is powered by a 10-nanometer Exynos 9611 chipset with four 2.3 GHz Arm Cortex-A73 cores and four 1.6 GHz Cortex-A53 cores. And its Mali-G72 graphics are also 3 cores. At On the other hand, in A52 we find the 8-nanometer low-power Snapdragon 720G processor. Lower, while increasing the frequency from 1.6 to 1.8 GHz, the relatively newer A55 has been selected. Adreno 618 graphics This chipset also has a clear advantage over the Mali-G72 MP3 on the A51.

    We see the level difference between the A51 and A52 processors in the Geekbech 5 test, where a larger number means higher quality. In this test, the A51 scores close to 340 and 1,300 units in single-core and multi-core modes, while the A52 scores close to 560 and 1,800 units in both single-core and multi-core modes with obvious differences. He leaves.

    https://mobiletony.com Comparison of Galaxy A51 and A52 - a difference beyond two generations

    A52 is also more successful than its competitor in graphics tests, and in a similar situation, we can speak of its complete superiority over the competitor.

    The A51 uses 4, 6 or 8 GB of RAM, although the version we had had only 4 GB of RAM. The A52, on the other hand, has the same amount of RAM. The type of these RAMs is not much different from each other and their LPDDR4X has created the same conditions.

    In terms of internal storage, however, the situation is different, and apart from the 64GB version for the A51, which is not available in the A52 with 128GB or 256GB of storage, the types of internal storage are also different. To determine the type of memory in these two phones, we go to the AndroBench test, in which the first option, Sequential Read rate, will be a measure of memory speed. The A51 is rated at less than 500 Mbps, indicating that the model has UFS 2.0 internal storage. In the A52, however, the situation is completely different, and with the speed reaching 940 Mbps, we can talk about the presence of faster UFS 2.1 memory in this model, which creates a distinct experience while using the phone. To better understand the importance of quality and faster memory, it is enough to note the sequential write speed in the second line of this test, which has increased from around 200 Mbps on the A51 to close to 500 Mbps on the A52. Thus, the process of storing data on this memory will be much faster than the A51.

    https://mobiletony.com Comparison of Galaxy A51 and A52 - a difference beyond two generations

    One downside to the A52 family account here is the combination of microSD memory slots, which will require the user to choose between a second SIM card or a memory card, while the A51 has a separate SIM card slot for the memory card. Was used.

    https://mobiletony.com Comparison of Galaxy A51 and A52 - a difference beyond two generations Communication options The maximum 4G download and upload speeds on the A51 are based on the device's processing chipset of 600 and 150 Mbps under LTE Cat.12 and Cat.13, respectively, and on the A52 these two speeds (again according to the specifications). Announced for the device chipset) has not changed much and reaches 800 and 150 Mbps (under LTE Cat.15 and Cat.13), respectively. Bluetooth 5, dual-band Wi-Fi and NFC connectivity are common among competitors in this comparison, and the same is true for satellite routing, with more accurate routing with dual-frequency connectivity in either. These models are not news.

    Strengths and weaknesses - Winner of the competition

    https://mobiletony.com Comparison of Galaxy A51 and A52 - a difference beyond two generations

    At a glance, the advantages of the Galaxy A52 over the Galaxy A51 can be summarized as follows:

    - Matte body and resistant to fingerprints < / p>

    - IP67 resistance standard with the ability to immerse the phone in 1 meter of clear water for 30 minutes

    - More screen light and higher refresh rate

    - Better quality main camera photography In both day and night modes

    - Higher quality 1080p / 30fps videos Main camera with OIS support

    - Better ultraviolet camera performance in both day and night modes

    - Relatively higher quality macro camera
