Galaxy A51 5G: Different Features

  • RAM: 6GB, 8GB
  • Storage: 128GB
  • Battery: 4,500mAh
  • Dimensions: 158.9x73.6x8.7mm
  • Weight: 187 grams

Unfortunately, the most popular phone companies are increasing the prices of their high-end devices every day. Those flagship phones that cost about $ 700 were left in the past. However, Samsung is one of those companies that have not forgotten users who want quality but at a more affordable price, and for this reason, recently launched the new Samsung Galaxy A51.

This device is last year's Galaxy A50 update. It offers a modern design and some high-end features but also sacrifices some performance and camera details for $ 400.

Will the Galaxy A51 be a good investment? Will it be able to compete with Apple's popular iPhone SE? 


The price of the Galaxy A51 is $ 399 for the version with 4G LTE and $ 499 for 5G.

The Galaxy A51 is now available for purchase on Sprint,  Verizon AT&T and Xfinity Mobile. T-Mobile, US Cellular, and in an unlocked version in the future.

At Amazon, this phone can also be purchased in international versions that also include Dual SIM.

The Galaxy A51 5G will arrive after the 4G LTE version.

Design: Almost like a Galaxy S20

The Samsung Galaxy A51 cell phone has a design very similar to Samsung's flagship phones, including the Galaxy S20 and Galaxy S20 Plus, not only because it has a rectangular camera module but also because the screen integrates the front camera through a hole in exactly the same position (centered).

If there is one feature that stands out and catches the attention of this phone is its design.

On the front of the phone, you can see an edge-to-edge screen, with a perforation cutout in the middle for the front camera. On the back, specifically in the upper left area, you will find a rectangular protrusion, which is where the camera is housed, similar to the Galaxy S20 series.

The rectangle that borders the rear camera doesn't protrude much, which not only makes the phone look sleeker but also allows it to be more stable when placed on the desk.

On the left side of the phone is the SIM tray, while on the right is the power button and volume control. At the bottom you'll see a USB-C port, and a headphone jack, which means you won't have to suffer when you want to charge your phone and wear headphones at the same time.

The screen of the Galaxy A51 is quite modern not only because it covers the entire front of the phone, but also because it has a large 6.5-inch size, much larger than the 4.7-inch screen of the iPhone SE or Pixel 3a.

Despite the fact that the screen is not as impressive as that of the Galaxy S20 series phones and the back is plastic instead of glass, the truth is that a phone with a lot of styles and a design that makes you fall in love.


The Galaxy A51's screen is 6.5 inches and boasts a 1,080 x 2,400 resolution, but perhaps most importantly its AMOLED technology, which offers deep black levels and vivid colors.

This quality makes the screen of this phone better than that of its closest competitor, the iPhone SE since we remember that the mid-range Apple phone adopts OLED technology. It also gives the device an advantage over the Moto G Stylus, which matches the resolution, but features LCD technology.

At the bottom of the screen, it has an optical fingerprint sensor. In the tests, the sensor worked well, although sometimes it took several seconds to recognize fingerprints, which can be a little frustrating.


The Galaxy A51 has an Exynos 9611 processor (the same as the Galaxy A50s and a small update compared to the Exynos 9610 of the Galaxy S50), 4GB or 6GB of RAM (or 6GB or 8GB in the Galaxy A51 5G), 64GB or 128GB of storage ( 128GB for the 5G version) with a microSD card slot and running Android 10 with One UI 2.0, the interface that first came to the Galaxy S10 with the Android 10 update.

This spec component isn't the most outstanding on the market and falls short of the processing power that the iPhone SE 2020 offers.

Overall, the Galaxy A51 has offered a very decent experience for this range, but I think the Exynos processor still lags slightly behind the graphics performance of Snapdragon processors in the range.

I say this because sometimes heavy graphics can be seen not as smooth as one would expect - the tests showed just this.

However, in general use, the experience is adequate, although I find it unfortunate that it does not distinguish itself in performance and power compared to Pixel 3A, one of its rivals that is already one year on the market.

Battery life

The Galaxy A51 has the same 4,000mAh battery from its predecessor the  Galaxy A50, which is exactly the same as the Galaxy S20 has. 

However, if you buy the 5G version you will get a 4,500mAh battery that is the same size as the Galaxy S20 Plus and $ 500 less than the Galaxy S20 Ultra.

At the moment, I've been testing it for a couple of days and its battery seems to last the entire regular day of use, which is good.

In our tests, the Galaxy A51 achieved 16 hours and 30 minutes, which is higher than the 15 hours and 45 minutes that the iPhone SE 2020 achieved, the 16 hours of the Moto G Stylus, and the 15 hours with 18 minutes of the iPhone 11.

However, this is also below the 19 hours that the Pixel 3A XL achieved, but it is very similar to the 16 hours and 15 minutes that the Pixel 3A achieved.

Inclusively, in the same test the Galaxy S20 achieved 14 hours in the same test and the Galaxy S20 Plus and Ultra achieved 16 hours in the same test when the screen was set to 120Hz. At 60Hz, the first achieved 19 hours and the other S20s achieved 21 hours.

Camera quality

One of the great attributes of Samsung phones is its camera and despite the fact that the Galaxy A51 is mid-range, it is not far behind.

At the rear, the Galaxy A51 features a four-lens camera. The main sensor is 48-megapixel, followed by an ultra-wide 12-megapixel sensor, another 5-megapixel macro, and a 5-megapixel depth sensor.

In the tests the camera manages to capture great photos in places with good lighting, probably due to its large 48-megapixel sensor. Also, it recreates the details of all the components of the shot with great accuracy and vivid colors. However, sometimes it exaggerates the intensity of the real colors and makes the photos look somewhat fictitious.

When the camera is tested in places such as poor lighting, the situation changed completely, as the photos weren't as good, the quality of the details and the vivid colors that stand out in the photos with good lighting were lost.

It is worth noting that this device also has a macro lens that unfortunately does not have its own autofocus. With it, you can achieve some good results with some work, but it is probably a function that not everyone knows how to use well.

Is it worth buying

The Galaxy A51 is a phone with great qualities and a convenient price, but it's not perfect. Surely for its price, Samsung has limited itself to making major improvements to its camera and has some software shortcomings that can be annoying. And in addition, it has two major competitors in the market such as the iPhone SE and the Pixel 3a.

However, it has a very elegant design and an extraordinary battery and if you can take advantage of some promotions such as the one offered by Verizon and Samsung, you could get a very good phone for less than $ 300 dollars.
