Review of Samsung Galaxy A31 and Samsung Galaxy M31 with huge batteries
Samsung Galaxy A31 and Samsung Galaxy M31 devices look almost like flagships but are sold cheaper. However, the manufacturer has another series of smartphones – Galaxy M. Soon it will appear in our country as well – the Samsung Galaxy M31 will be one of the first gadgets of the line to come to Belarus. Below we understand what its pros and cons are, and at the same time, we are testing another new product – Samsung Galaxy A31.
Galaxy M series smartphones first appeared in January last year and targeted the Indian market. Their main feature is high-capacity batteries. They have not departed from this concept today. The starting version of the Galaxy M31 (with 64 GB of memory) will be sold in Belarus for 639 rubles, Galaxy A31 (64 GB) – for 589 rubles.
In design – no surprises
Despite belonging to different lines, the Galaxy A31 and M31 look similar to each other. Cases – plastic, power and volume keys – on the right side. Both devices are capable of simultaneously working simultaneously with two nanoSIM cards and a microSD memory card.
In place is a 3.5 mm headphone jack, charging ports are USB Type-C, single speakers, no stereo. Front cameras are located in the drop-drop in the upper part of the displays. In general, the asset contains the entire necessary set for a “strong” smartphone at the beginning of the year from the middle price category.
Once again, you can complain only of the plastic rear panels. Someone may also not like the rather massive “chins” at the bottom of the screens.
And now – to the differences (but they are not the most significant). Despite the difference in the volume of the built-in batteries, the Galaxy M31 is only 0.3 millimeters thicker than the Galaxy A31. The difference in weight is insignificant – 185 and 191 grams respectively for A31 and M31.
But with the fingerprint scanner, things are better in the Galaxy M31. The sensor is already “old fashioned” located on the back of the smartphone and works almost flawlessly. The Samsung Galaxy A31 has an optical sensor built into the bottom of the display. It acts noticeably slower in comparison with the Galaxy M31. Anyway: display fingerprint scanners more or less tolerably work only inexpensive flagships – at least for now.
In short: the Galaxy M31 and Galaxy A31 are unlikely to surprise anyone with their design. Smartphones look the same as most other models – both from Samsung itself and from other manufacturers. But this is not bad. In any case, the ergonomics of devices does not raise questions. I’m only upset with plastic cases. But honestly, you’ll almost certainly put gadgets in cases.
What about the screens?
The diagonal of the displays of both smartphones is 6.4 inches, the matrix is AMOLED, the resolution is Full HD + (more than 400 PPI). The advantages and disadvantages of panels are typical for screens of this type. The default color rendering is bright and saturated, the brightness is above average, there is an inversion of white color even with a slight tilt of smartphones.
Something like this can describe the display with an AMOLED matrix in a smartphone from almost any manufacturer in the middle price category. All this applies to the new Galaxy. Does this mean that the displays let us down? Not at all. Smartphones are a pleasure to use thanks in large part to their panels. The clarity of the picture is enough, you can watch YouTube videos with friends thanks to the wide viewing angles.
In general: the displays in the new Galaxy are, rather, the forte of the devices. I did not notice any significant flaws. Taking the device out of the box and activating them, the average user will almost certainly be satisfied. But I repeat: the same can be said about most other smartphones with a price of about $ 300.
Performance could be higher
This is probably one of the most controversial issues in both smartphones. Galaxy A31, oddly enough, runs on a processor from MediaTek – Helio P65. Most Samsung devices are typically based on Qualcomm branded Exynos or Snapdragon. RAM type LPDDR4X in the device (in our configuration) 4 GB.
The device is gaining a little more than 160 thousand points in AnTuTu (v8) – far from a record result. But even if you do not focus on benchmarks: Galaxy A31 has not felt the fastest device – jerks are felt even when working with the interface. You can play, but only at medium graphics settings – in any case, the settings above in Call of Duty Mobile did not work out.
The Galaxy M31 uses the proprietary Exynos 9611 processor. The same chip, for example, is installed in the Galaxy A51. The result of smartphones in the synthetic test AnTuTu (v8) is already 190 thousand points. But then again – calling the device superfast will not work.
Although progress is being made compared to the Galaxy A31 on MediaTek, in any case, the interface works smoothly. In the same Call of Duty, it turned out to set high (but not maximum) settings. In addition, the Galaxy M31 is capable of recording 4K video, the Galaxy A31 – only Full HD.
Below are the throttling tests of the Galaxy M31 and A31. Both copes with this test with dignity – the heating of the case is negligible:
In general: the performance of both smartphones is now enough, but without any margin for a year and a half ahead. The Galaxy M31 on the Exynos 9611 feels better, but you still can’t call the difference critical.
Simply put: all the popular and necessary applications – mail, cards, banking programs, instant messengers and social networks, a browser (if you do not go too far with the number of active tabs) – go without problems. Play, most likely, will work out, but you will have to sacrifice the graphics settings.
Battery life is the strongest side of smartphones
Galaxy A31 is equipped with a 5000 mAh battery, Galaxy M31 – at 6000 mAh. I must say right away that this is the strongest side of the devices, from one charge the devices “live” significantly longer in comparison with most competitors.
When I started testing the devices on Tuesday, they were charged almost to the limit. By Wednesday evening, “drop off” them to zero failed. I activated smartphones via Wi-Fi, installed the test application package on them, set up several mailboxes, downloaded Telegram and a couple of games. In general, the load was at least no lower than when using devices by an ordinary person immediately after purchase.
True, there is still a minus. Despite the fact that the devices support 15-watt accelerated recharging, Galaxy A31 takes more than two hours to replenish energy from 0 to 100% and three hours for Galaxy M31. USB-C ports are used to connect the charging cable.
In general: autonomy is the main feature of smartphones. Both can last one and a half to two days without connecting to an outlet. For this, it is worth noting not only increased batteries but also screens made using AMOLED technology. The Galaxy M31, at least in theory, can last even longer without being plugged in. There is only one minus – a long charge.
Both smartphones are equipped with cameras with four modules. The differences are only in the main: the Samsung Galaxy A31 uses a photosensor with a resolution of 48 megapixels (f / 2.0), in the M31 – 64 megapixels (f / 1.8). The asset is ultra-wide cameras of 8 megapixels, as well as sensors for macro photography and measuring the depth of field by 5 megapixels.
Expected when shooting smartphones use artificial intelligence algorithms. It’s a pity that you can’t switch from a regular camera to “shirk” during video recording. And one more thing: by default, devices take pictures respectively in 12 megapixels and 16-megapixel modes, programmatically connecting four neighboring pixels into one larger one.
These are examples of shots from the Galaxy A31:
Despite the fact that the new Galaxy A31 and Galaxy M31 belong to different lines of the company’s smartphones, they have a lot in common.
The cases are made in the same patterns, the screens are of the same diagonal, the cameras are similar. Of the pluses is the ability to install two SIM cards and a memory card at once. With ergonomics, everything is in order – despite the impressive size of batteries, the devices weigh less than 200 grams. Do not forget about Samsung Pay’s support.
But the strongest side of both devices is the outstanding battery life on a single charge. Still, 5000 mAh and 6000 mAh batteries (respectively for A31 and M31) make themselves felt – both gadgets allow one and a half to two days to work actively. Perhaps, if necessary, it will be possible to squeeze more out of the Galaxy M31, but it has not yet been verified. As well as discharge them “to zero” on a single charge during testing.
But there are also disadvantages. The first is the slow recharging. Despite the support of 15-watt power adapters, it takes more than two hours to recharge energy. The second is performance. It is hardly necessary to speak about the power reserve for the future, in any case, if we keep in mind the Galaxy A31 on the MediaTek processor.
Frankly speaking: I liked the Samsung Galaxy M31 a bit more, especially since the price difference is not the most significant M31 and A31, respectively). Although the A31 is sure to find its buyer.
