Samsung Galaxy A52 Review: Samsung has launched Samsung Galaxy A52, a new smartphone in the Galaxy A series. Galaxy A51 has been one of the most liked Android smartphones in the last year and now the company has launched Samsung Galaxy A52, is its successor?. This phone comes with strong specifications. The reason for the high demand of Galaxy A51 was not just its specifications, but also the build quality and in-hand feel of the phone. Due to this, the brand had the responsibility to make the Galaxy A52 superior to the previous smartphone (Galaxy A51). For the last few days, we have been using the Galaxy A52 smartphone, so let’s know whether Samsung has been successful in this endeavor?
Design
Samsung Galaxy A52 comes with attractive design. The phone comes with a polycarbonate back, metal frame. The back panel gives a premium feel even though it is plastic. That is, you will not find this phone ‘cheap’ in any way. However, the talk of glass back is different. Fingerprint stains do not come in the rear side of the smartphone, but due to being plastic, it can be scratched soon. Therefore, our advice would be to use the phone with a back cover.
The weight balance of the phone is excellent, which keeps the grip on it. There is no problem in using the handset with one hand. The device has a Mate frame, which gives a better touch to its look. Volume buttons are found on the right side along with the power button. The top has a sim-tray, while the bottom gets a 3.5mm audio jack and Type-C port with speaker grille.
Samsung Galaxy A52 Review: The phone has a 6.5-inch full-HD + Super AMOLED Infinity-O display, which comes with a refresh rate of 90Hz. The display offers excellent brightness. The phone’s display is well seen not only in low light areas but also in the sun. The screen is quite bright, so there is no problem in using it at any place. The phone has an option of both 90Hz and 60Hz refresh rate. The display is quite smooth. We have not seen any kind of problem.
Processor, Operating System and Performance
The Galaxy A52 has a Qualcomm Snapdragon 720G processor. Even if you find this processor outdated in number, Samsung has optimally optimized its smartphone. There is no problem in terms of performance. Games such as Call of Duty in the handset can be played on a high setting. While playing the game, no problems like heating the phone or frame drop have been found.
This smartphone comes with an IP67 rating, which is a very good thing. In the mid-range budget, only a few smartphones with IP67 rating have been seen. This rating means that the phone is water proof. This phone will work even after falling into the water. It gets OneUI 3.1 based on Android 11. You get many apps pre-installed in the handset.

Galaxy A52 comes with many Samsung apps (like Samsung Health, Smart Thinks). Apart from this, many apps like Snapchat, CandyCrush, Mojo are available. However, the good thing is that you can delete them. There is no visible reduction in the performance of the phone. The UI responds very fast. At the same time, Samsung has said to provide updates in their phones for three years, so there is no problem about security patches and latest updates.
Battery
Samsung Galaxy A52 Review: The smartphone has a 4500mAh battery, which comes with a 15W charger. However, the phone supports 25W charging. Samsung could offer a 25W charger with the phone, which is available in the Galaxy F62 smartphone. Note that the Galaxy F62 comes at a lower price than this A52. The battery life of the device is also fine. In single charging, you can use it almost all day, but the phone takes time to charge (from the charger found in the box). The company has made a small cut here. It takes more than one and a half hours for the Galaxy A52 to be fully charged with a 15W charger.
The Samsung Galaxy A52 has a quad rear camera setup. The main lens of the phone is 64-megapixel, which comes with OIS support. OIS or optical image stabilization has the advantage of making videos. Video shot with the help of this feature is more stable. Apart from this, the phone has a 12MP ultra wide angle lens, a 5MP depth sensor, and a 5MP macro lens.
Whether it is to take photos in low light or in natural light, the smartphone performs well in both places. However, in low light areas, the phone sometimes over-saturates the color in photos. Photos taken in wide angle or macro mode are good. In the camera app, you also get an option called Fun. With this help, photos can be taken using Snapchat filters. For selfie, the company has given 32MP lens, which works well. We are sharing the camera sample with you, so that you will understand it better.
Other Features
The phone comes with an in-display fingerprint sensor, which works fast. The smartphone comes with Always On Display feature. Talking about connectivity, the signal reception in the phone is also good. There is no problem in calling. The phone has a stereo speaker, which is excellent. On many occasions its sound sounds very loud. The gaming experience makes the speaker even more exciting. People watching the video will like the phone speaker a lot. The phone also has a 3.5mm audio jack hole.

How is this smartphone?
This Samsung smartphone is a great mid range device. The Galaxy A52 does not offer 5G connectivity, but the question is, are you buying the phone keeping only 5G in mind? If your answer is yes, then you can see other phones. At the same time, if your answer is in ‘No’, then it is a great device. According to its price, the smartphone has a strong camera and a combination of excellent performance. The IP67 rating further strengthens this smartphone’s favor. Overall, this Samsung smartphone can become a great mid-range device.
The disappointment of having a plastic back panel in the phone disappoints. Since this Samsung smartphone comes in a budget of more than 25 thousand rupees, the plastic panel makes it feel like cost cutting.
The lack of 5G is also one of the drawbacks of the phone. However, the possibility of launching of 5G in India so soon is less likely.
The charger that comes with the phone is just 15W. While the company had given a 25W charger in the recently launched Galaxy F62 smartphone (Galaxy F62 price is less than Galaxy A52). It would have been better if there was a 25W charger with the Galaxy A52 as well.

What types of batteries suitable for campers, vans or trucks are on the market? Three: AGM, GEL and Lithium.
Let’s begin to understand the substantial difference between GEL and AGM, which are based on the same technology but differ in the substance that covers the electrolytes. We are interested in knowing that both can be installed in any position, do not risk losing liquids and can be used in poorly ventilated environments. AGM vs standard battery , AGM batteries perform slightly better in terms of faster discharges, while GEL is recommended for slow discharge uses and where there are solar panel installations. GEL batteries also work a little better at higher temperatures.

While adapting very well to the slow discharge characteristic, these three technologies have different features from each other (and even by a lot). What mainly differentiates them? Apart from the price, which we will see, these batteries differ from each other in their ability to be fully discharged (sincerely), the number of life cycles, the speed of recharging to which they can be subjected, their specific weight and the price. We don’t want to complicate the situation, and we try to explain these concepts better:
Deep discharge: basically, it’s how much we can afford to empty our fuel tank. We will see how AGM and GEL batteries force us always to keep a lot of fuel in the tank. In short, it’s like filling up every time but needing help to use it all—an excellent bummer.
Life cycles: Even more straightforward, how often can we go to the dispenser after emptying our reserve? In practice, this parameter indicates longevity in terms of the life of your investment in batteries. Note that often in the battery datasheets, a duration value in years is displayed, but this is valid when the batteries are not used.
Charging speed: exciting data because it indicates how long our batteries can still be used. In practice, we will see how lithium batteries support very fast recharges, optimizing above all any fuel costs of the generators, or optimizing the energy supplied by the solar panels.

The data with which the recharging capacity is indicated is the number of times the power of the batteries. If a 400Ah battery bank is charged at 1C, it is supplied 400Ah per hour during the recharging phase. In the diagram below, we see that, for example, lithium batteries can withstand charges at 0.5C without problems, i.e. in the example shown above, 200Ah. At the same time, the equivalent AGM or GEL would only support 400*0.2 (0.2C)=80 Ah. This data is also essential for choosing your charger.
Weight: Trivially, lithium batteries weigh, on average, three times less than the others for the same Ampere supplied.
Price: There is little to be said and done. Lithium batteries currently cost a lot. But remembering that these can be downloaded more significantly, additional calculations will have to be made to understand the actual cost/benefit ratio. Let’s start by saying that, for example, a good quality 12V 220Ah battery can cost around 400 Euros, while buying a 12 Volt 200Ah Lithium battery will take approximately 2800 Euros.

Batteries, the sizing of your service counter
Given what was described in the previous paragraph, are we faced with a fundamental choice, Lithium or AGM/GEL?
Let’s take up all the data obtained and give two examples to evaluate our needs. N.B. In our calculations, we will consider the use that does not expect to fall below the maximum expected discharge values to obtain the complete life cycles. For ease of understanding, we will use a 12 Volt battery bank in the example.
Assuming that we need 1230 Watts of the reserve, we get the following:
Advertisement
Regarding GEL/AGM batteries: 1230 Watt / 12 (Voltage of our bank) = 102.5 Ampere. However, our bench must have a capacity such that the 102.5 Ampere are at most 30% of the total capacity. So we obtain that our bank must be made up of: 102.5 (Ampere) * 100 / 30 (Percentage of maximum use) = 341 Ampere. These are, therefore, equivalent to a total of 341 Ampere * 12 Volt = 4100 Watt.
As far as lithium RV batteries are concerned: 1230 Watt / 12 (Voltage of our bank) = 102.5 Ampere. However, our bench must have a capacity such that the 102.5 Ampere are at most 80% of the total capacity. So we obtain that our bank must be composed of 102.5 (Ampere) * 100 / 80 (Percentage of maximum use) = 128 Ampere. These are, therefore, equivalent to a total of 128 Ampere * 12 Volt = 1538 Watt.
To this must be added the duration in terms of cycles, which therefore leads to considerable differences in management costs of our plant. In practice, we obtain a period roughly double for the latter by evaluating an AGM bank with a time of approximately 1200 cycles compared to 2500 of the lithium battery bank. Let’s see specifically:
Advertisement
GEL/AGM battery bank: Two 12 Volt 220 Ah batteries in parallel will be needed to obtain a 12 Volt 440 Ah bank for a total of 5200 Watts, sufficient to cover the calculated requirement of 4100 Watts. The average cost of this bench is around 800 Euros. This bench will need to be replaced indicatively once (remember the double duration previously calculated) to arrive at the same Lithium bench’s course, bringing the management cost to 1600 Euros.
Lithium battery bank: A 12 Volt 160 Ah battery will be needed to obtain a power of 1920 Watts sufficient to cover the requirement of 1538 Watts that we have calculated. The average cost of this bench is around 2300 Euros.
However, we also want to draw attention to the comparison in terms of weight, given that, as we said, it is decidedly in favour of lithium batteries by a factor of 1 to 3. In the example shown above, the GEL/AGM battery bank would weigh about 130 Kg against approximately 40 of the lithium equivalent, which also has a better ratio in terms of size.

As we said before, describing the different types of batteries in detail, what matters during your system’s review or installation phase is to understand your needs in terms of energy reserve. After that, the choice is up to your wallet.
We can give an indication of the choice we made on our Valentino truck, where we installed a bank made up of 8 Renogy GEL batteries for a total capacity of 880 Ampere at 24 Volts or about 21 kW of power. This entailed the preparation of adequate space, which was divided into two distinct compartments, one under the garage and one in the rear garage.
Although driven by our interest in new technologies, where it is clear that lithium batteries will be the investment for the future, we have evaluated the decision to invest a lot of money too prematurely. Our choice was also made considering that lithium batteries 12v, 24v or 48v indeed need fewer elements, but if these were to fail, the total capacity would also be affected. In the example shown above, for example, it is evident how the breakage of the 160 Ampere lithium battery creates the total absence of energy, as well as real economic damage equal to 2300 Euros. Any damage to one of the two AGM batteries, on the other hand, would lead to a financial loss of 400 Euros and limit the system’s use by 50%.
