Samsung Galaxy A51 vs A71 in the comparison test June 2020
Samsung offers OLED displays, quad cameras and an excellent battery life for the Galaxy A51 and A71. The test shows what the smartphones have to offer.
The Samsung Galaxy A50 is said to be the fourth best-selling smartphone in 2019 according to Canalys market researchers. The Galaxy S10 + only made it to tenth place. Samsung’s new mid-range Galaxy A51 and Galaxy A71 should now build on the success of its predecessors and offer good features at a reasonable price. The test shows whether the A51 and A71 are up to the task.
Galaxy A51 and A71: dimensions, design and feel
The most obvious difference between the two smartphones is the size: whereby the Galaxy A51 is five millimeters shorter than the Galaxy A71. So it’s a little more manageable.
- Galaxy A51 : 159 x 74 x 8 millimeters, 170 grams
- Galaxy A71: 164 x 76 x 8 millimeters, 179 grams
The weight difference (170 vs. 179 grams) is negligible, because both models are real lightweights in terms of their size, which is probably also due to the choice of materials: Although the Galaxy A51 and Galaxy A71 are top-quality as usual from Samsung, the back is made each made of plastic and is therefore more susceptible to scratches.
We also miss protection from water and dust, but this is rarely found in the price range. In contrast to an enclosed protective cover, which Samsung unfortunately saves. Despite the plastic, the devices are valuable and we also like the design quite well. Here, both smartphones have a hatched back, which in turn is divided into triangular shapes. All three colors also shimmer with a rainbow effect in the light.
Large, good OLED displays
But of course the real action takes place on the front: Samsung uses OLED displays with 6.7 or 6.4 inch diagonals and a resolution of 1080 x 2400 pixels. The screens fit nicely into the frame and have rather narrow edges. Compared to its predecessors, Samsung does not have a notch and installs the front camera directly in the panel.
Interesting: The recess on the Galaxy A51 is two millimeters smaller, even though the same camera with 32 megapixels sits behind it. An optical fingerprint sensor is also hidden under the screen in order to unlock the devices – this takes a moment to commemorate.
Otherwise, the display of the Galaxy A71 can really score and is one of the best ads in the price range! The OLED is extremely stable in viewing angles and also impresses with very good contrasts. Its display brightness could be even brighter at 420 cd / m2, but it regulates up to 852 cd / m2 in the sun and thus guarantees optimal readability.
The display of the Galaxy A51 drops somewhat in terms of quality due to the price, but also remains at a good level overall. It is somewhat dependent on the viewing angle and can score in bright surroundings with a not quite as good readability as its big brother. The display brightness of the OLED is 432 cd / m2 a bit brighter than that of the A71, the outdoor boost creates a very good 715 cd / m2.
Differences in system performance and scope of delivery
Galaxy A51 and A71 differ not only in size, but also in the inner values. The Galaxy A71 is more powerful, with Samsung using Qualcomm’s Snapdragon 730 a chip of the upper middle class and 6 GB RAM. The system performance is therefore impressive and also makes graphics-intensive gimmicks possible – even if not in the highest settings.
In contrast, Samsung’s mid-range Exynos 9611 chip with 4 GB of RAM works in the Galaxy A51. The system performance is around a quarter lower than that of the A71, which is particularly noticeable in graphics-intensive applications. For normal everyday tasks, however, you are very well armed in terms of performance. There is enough space on both smartphones with over 106 GB.
In terms of software, the current Android 10 is preinstalled, over which Samsung has slipped its One UI user interface. The Bixby routines integrated into the system are particularly useful here. With these, the smartphone learns the daily processes of the wearer and controls the functions of the phone automatically – even location-dependent. For example, the smartphone automatically activates the WLAN at home and switches off NFC and Bluetooth.
Both Galaxy models are tied in terms of connectivity: fast ac-WLAN, NFC, Bluetooth 5 and LTE Cat. 12 with 600 Mbit / s in the download are available on both devices. Practical: you can use two SIM cards and a MicroSD for memory expansion at the same time on both devices.
Still important for many is the jack connection, which is also available in both galaxies. However, the A51 provides very little voltage with 180 mV, which could make the operation of high-end headphones more difficult.
When it comes to the scope of delivery, the more expensive Galaxy A71 gets more points: Samsung includes high-quality in-ear headphones here, the Galaxy A51 has to be satisfied with normal stereo headphones. As already mentioned, a protective cover is missing and a screen protector is not applied at the factory.
Image quality and test result
Image quality of the quadruple cameras partly mixed
As far as the camera equipment is concerned, the differences are not huge: Both the Galaxy A51 and A71 come with a quad camera, in which one lens only collects depth data. The main camera of the A71 is very high-resolution, with a maximum of 64 megapixels. As usual, several pixels are added together using pixel binning, resulting in a photo size of 16 megapixels. In bright surroundings, the A71 takes good photos, in the dark the picture quickly becomes a bit mushy – the quality determined by our laboratory is satisfactory here.
The same applies to the Galaxy A51, whose wide angle has a 48 megapixel sensor. The best way to snap photos here is with 12 megapixels, they are rather mediocre in bright and poorly lit environments. Samsung does a lot of digital resharpening here, fine details also have a hard time. Especially when it gets dark, the photos are washed out and mushy.
The look is still sufficient for snapshots. Pictures with the ultra wide angle (12 MP each) look about equally good, as usual, there is a lack of detail resolution. The additional built-in macro optics (5 MP) provides interesting results as long as you hit the focus area, but has a rather limited added value.
Excellent battery life and good reception
There is good news from the laboratory: the reception values are in the green for both the Galaxy A51 and the A71 – which also applies to the telephony acoustics of both models. Only the Galaxy A51 has a bit of a problem with noise cancellation.
The battery life of the Galaxy A71 is particularly good at just under 12 hours, the Galaxy A51 also lasts a very long time in our laboratory test at 9:40 hours. Fast charging with 25 watts meanwhile only supports the A71. With the A51, you have to plan a little more time with a 15-watt charger.
Both models do not support wireless charging, but this can be expected in the class.
Test conclusion for the Galaxy A51 and A71
Samsung has once again launched two good mid-range smartphones with the Galaxy A51 and A71. We were particularly impressed by the latter: The A71 is a good choice for all those who want a small performance buffer in addition to a very good display and excellent battery life and who often use their device to play.
Nevertheless, the Galaxy A51 also offers an outstanding price-performance ratio and is worth a look for price-conscious people. In our opinion, Samsung still has some catching up to do in terms of photo quality. The competition in the price segment does that better.
