The Samsung Galaxy A51, a mid-range smartphone that was launched in January 2020, proved to be a bestseller that obtained bouquets from the tech press and customers because it provides improbable value-for-money. A yr on, I examined the Samsung Galaxy A51 to see whether it is nonetheless price selecting one up as we speak.

My transient opinion on the Samsung Galaxy A51
The Samsung Galaxy A51 is a mid-range smartphone that was first introduced in December 2019 and launched in January 2020 at a $379 value level. In July 2021, the smartphone is not offered by Samsung formally, albeit carrying a $280 price ticket on its official retailer.
If you wish to choose one up now, I can solely discover it on third-party sellers in Market within the 4GB RAM configuration solely.

When it comes to {hardware} specs, there's an AMOLED show, a quad-camera module (48+12+5+5 MP), an Exynos 9611 SoC, and a 4,000 mAh battery that accepts wired 15 Watts quick charging.
If we start on the beginning value of $379, then the Samsung Galaxy A51 has no argument to make in opposition to a Redmi Be aware 10 Professional or a OnePlus Nord CE. Even when we have been to take the present value of roughly $280, the competitors stays fierce with the presence of the Realme Eight Professional or the Redmi Be aware 10 5G.
As we'll see in my full evaluate, some parts of the Samsung Galaxy A51 nonetheless maintain up properly in 2021 resembling its lovely AMOLED show. General, I felt like I had an outdated mannequin in my palms.
Design and display screen: The plastic look hasn't aged one bit
In the case of design and the show, the Samsung Galaxy A51 sports activities a flat 6.5-inch AMOLED panel with a plastic again, all crammed into a reasonably huge 158.5 x 73.6 x 7.9 mm kind issue whereas tipping the dimensions at 172 grams.
What I favored:
- The AMOLED display screen stays very succesful
- 3.5 mm jack and a microSD reminiscence card slot
- Reflective impact of the coat on the again
- The slim digital camera module
What I disliked:
- 60Hz refresh price
- Tough end in sure locations
- No IP certification

I actually just like the reflective impact that the again coating delivers in a pearly white colour, full with diagonals and vertical stripes.
I additionally favored the digital camera module that hardly protrudes, though that is partly as a result of the truth that the Samsung Galaxy A51 is moderately thick. However, I discover that the end will not be fairly refined in chosen areas, particularly across the USB-C port and the three.5 mm audio jack, the place you may clearly see the deformation within the plastic body on the entrance of the ports.

As for the show, you get an excellent Tremendous AMOLED panel that measures 6.55-inches throughout diagonally in Full HD decision of 1080x2400 pixels, or 405 dpi pixel density. The utmost brightness of 630 nits (410 on common) is sweet sufficient with out going overboard. The refresh price maxes out at 60 Hz, however that didn't hassle me a lot, though I did see the distinction in comparison with the 120 Hz refresh charges that my eyes are used to.
I additionally welcome the presence of a 3.5 mm jack, a twin SIM port and a microSD slot to develop storage as much as 512GB. There isn't a IP certification, although.

A few of the ending touches are questionable. You'd be capable of see it if the USB-C port was IN FOCUS!!! / © NextPit
General, the Samsung Galaxy A51 stays moderately present visually in 2021, with the smartphone barely getting old. I am actually not a fan of the "all-plastic" strategy although. The display screen is great, however I am unable to assist however consider smartphones which might be offered for lower than $300 and even $200 that include the next refresh price. Providing an AMOLED show on the mid-range system is not thought of as a worthy feat in 2021.
Interface: OneUI 3.1 and one other Three years of assured updates
The Samsung Galaxy A51 at the moment runs on OneUI 3.1 that's primarily based on Android 11 and has obtained the Might 2021 Android safety patch.
I am not going to enter element about this Android pores and skin that you're already accustomed to. However the weak spot of the Exynos 9611 SoC didn't permit me to benefit from the wonderful person expertise that's usually related to OneUI.
Nevertheless, it is price remembering that the smartphone was first launched with OneUI 2.Zero that's primarily based on Android 10. And in keeping with Samsung's newest replace coverage, the Galaxy A51 will profit from Three main Android variations and Four years of safety updates.
Should you purchase this smartphone now, it'll obtain Android 13 in addition to safety patches up until 2023. At present, the smartphone has already dropped to the underside tier when it comes to safety replace frequency. Thus, you'll solely obtain one safety replace per quarter. This frequency is more likely to be decreased to twice a yr within the remaining yr of its life cycle.

Regardless of being launched final yr, the Samsung Galaxy A51 is more likely to be saved up to date longer than its Redmi or Realme counterparts that have been launched in 2021.
Efficiency: Exynos 9611 falls quick
The Samsung Galaxy A51 packs a 10 nm octa-core Exynos 9611 SoC and is mated to a Mali G-72 GPU and Four GB of RAM.
What I favored:
- No overheating points, which is one thing uncommon lately
What I disliked:
- Lackluster efficiency
- SoC was already not aggressive in 2020
- Slowdowns within the interface
- Gaming expertise was not very nice
Armed with a year-old mid-range SoC and an unlucky Four GB of RAM, you clearly should not count on a efficiency monster.
Quite the opposite, the Samsung Galaxy A51 actually struggled by on a regular basis duties. I skilled slowdowns within the interface, a delay when launching purposes, or making transitions whereas multitasking. In regular use and with none utility operating within the background, 2.2 of the Four GB RAM was used, leaving 525 MB obtainable. So I solely had successfully 1.Three GB of RAM obtainable.
The slowness was additionally skilled after I put in the OneUi 3.1 replace and the newest safety patch, the place the set up took a extremely very long time to finish. And I will not even enterprise into in-game efficiency since most titles launch with "common" graphics by default and virtually by no means run at 30 FPS consistently.

| Mannequin/Benchmark | Samsung Galaxy A51 | Redmi Be aware 10 Professional (SD 732G) | Realme Eight Professional (SD 720G) |
|---|---|---|---|
| Geekbench single/multi | 348/1265 | 569/1780 | 568 / 1685 |

| Passmark reminiscence/disc | 12.829 / 34.829 | 18.743 / 38.325 | 19.799 / 38.683 |
The one optimistic level is that smartphones launched in 2021 are inclined to overheat to the purpose of burning your fingers, which is one thing the Samsung Galaxy A51 would by no means do because it all the time stays at an inexpensive temperature.
Throughout my benchmark classes utilizing the 3DMark Wild Life Stress Check that simulates intensive gaming use, the Samsung Galaxy A51 maintained a low however fixed efficiency stage. However, it skilled a giant drop within the body price over the last check loop each single time (Three classes have been carried out in complete), bringing down the total rating of the smartphone.

General, whether or not we discuss with the $379 Samsung Galaxy A51 or the $280 that it's being offered for at the moment, the efficiency/value ratio is clearly not attention-grabbing sufficient to show your head as you will discover much more aggressive fashions from its competitors. Regarding this level, the Samsung Galaxy A51 is undoubtedly outdated in 2021.
Picture: The 48 MP quad module nonetheless holds up properly
The Samsung Galaxy A51 packs a quad-camera module with a 48 MP wide-angle predominant lens, a 12 MP ultra-wide-angle, and a duo of macro and depth sensors of 5 MP every.
What I favored:
- The digital camera module stays aggressive in 2021
- Appropriate daytime wide-angle pictures
- Large dynamic vary
- Colorimetry is well-managed regardless of a slight saturation
What I disliked:
- Disappointing night time mode efficiency
- A number of distortion with its extremely wide-angle lens
- Restricted digital zoom
- Fussy focus efficiency in macro
48 MP predominant lens
In the course of the day and beneath good lighting circumstances, the Samsung Galaxy A51's digital camera module nonetheless holds up very properly and reveals us simply how little the pictures {hardware} has developed in mid-range smartphones over a yr.
Pictures captured with the principle 48 MP sensor are usually not mind-blowing, however the stage of particulars is right, with a wide-enough dynamic vary even when it entails a posh publicity setting. Colours are flattering to have a look at, though Samsung has the tendency of saturating colours till it displeases many customers.

The extremely wide-angle can be moderately efficient with its large FOV of 123°. Nevertheless, you will should take care of very pronounced distortion on the edges of the picture in addition to extra random publicity administration, which might generally result in inconsistency with pictures when captured at wide-angle.

As for the zoom, it's important to make do with a purely digital magnification from the principle lens starting from 2x to 10x.
Zoom 2x, 5x, and 10x
With such low magnification, there's a minimum of a greater probability to acquire a usable end result. I believe the outcomes are fairly good so long as you restrict your self to only 2x zoom.
Zoom 2x, 5x, and 10x
However, I used to be very hardly ever satisfied by the outcomes of the 5x and 10x photographs. That is particularly since with out the presence of optical stabilization, the main target runs all over capricious and you will not all the time escape movement blur as you may see beneath.
Zoom 2x, 5x, and 10x
As for the macro sensor, I discovered it refreshing {that a} mannequin launched in 2020 would not accept a 2 MP module like a lot of the smartphones did in 2021. I discovered the main target space to be too slender and whereas it suffered from the identical stabilization considerations, the macro photographs turned out fairly good to me when all the proper circumstances have been met (a minimum of 1 out of two, as proven beneath).
5 MP macro lens
At night time, I discovered the pictures to be disappointing total. The night time mode does handle to catch up a bit with the scene by lighting it up extra to indicate extra particulars. However the software program processing is simply too aggressive and we frequently ended up with an excessive amount of digital noise.

General, I discovered that the Samsung Galaxy A51's digital camera module hasn't aged that a lot in comparison with what you'll find on this value vary this yr. The picture rendering will not be that nice, however I moderately loved a lot of the pictures that I used to be capable of seize with this smartphone.
Battery life: Tremendous sluggish charging velocity by as we speak's requirements
The Samsung Galaxy A51 packs a 4,000 mAh battery that accepts 15-watts of wired "quick" charging.
What I favored:
What I disliked:
- Common battery life
- Quick charging is simply too sluggish
A 4,000 mAh battery capability is taken into account to be moderately low lately, particularly for a mid-range smartphone.
With typical utilization and a mean display screen time of 6 hours per day, I used to be capable of final for barely greater than 12 hours earlier than seeing the battery life fall beneath the 20% mark. My greatest 'rating' was 14h 22m after I went out for a photograph shoot over the weekend and my display screen time was barely extra restricted (4h 30m).
However, the charging time was unbearably lengthy. I do know iPhone customers will not perceive why I am making such a giant fuss out of this since they're used to 20-watt charging. However I believe Samsung is critically lagging behind on this regard, even with 25-watt in its flagships.
Aside from the efficiency, that is the place the true drawback lies. If it takes greater than 1h 30m to completely cost a mid-range smartphone in 2020, that is not the case in 2021.
The Samsung Galaxy A51 provides a mean battery life and nothing else. Far sooner and higher charging capabilities could be discovered for a similar value on 2021 fashions. However the true drawback is its 'quick charging', which isn't quick in any respect.

Conclusion
Personally, I do not suppose the Samsung Galaxy A51 stays a good selection to choose up in 2021.
The smartphone remains to be aggressive in some facets together with the display screen high quality and the first rate efficiency of its 48 MP quad-camera module.
Samsung's 4-year software program assist makes the Galaxy A51 extra sturdy than virtually all of its opponents launched this yr on the identical value.
However primarily based on its launch value of $379, I would moderately choose up a Redmi Be aware 10 Professional with its 120Hz AMOLED show, 108MP predominant digital camera module, and 5,020mAh battery that provides 33W quick charging, all for $299 for the 6 GB RAM/128 GB configuration.
Even when we have been to take the present value round $270, I'd moderately select a Realme Eight Professional with a 60 Hz AMOLED show, a quad-camera module with a 108 MP main sensor, and its 4,500 mAh battery that helps 50W quick charging for simply $279 for the Eight GB RAM/128 GB model.
All of the extra vital, I couldn't find the Samsung Galaxy A51 as a brand new system from "official" e-tailers. For a Market buy, I discover the worth/efficiency ratio to be an uninteresting affair. Therefore, I will not advise you to choose up the Samsung Galaxy A51 in 2021.
