Samsung Galaxy M51 Review

Samsung Galaxy M51 is a smartphone that will amaze you with its battery capacity. As a representative of the M-series of the South Korean manufacturer, it has other advantages - Qualcomm Snapdragon processor, quality display, good set of cameras and stylish vision.


Visually, the Samsung Galaxy M51 stands out with its large size. Its display diagonal is 6.7 inches. It, together with the volumetric battery, can not but affect the dimensions of the device. The weight of the Samsung Galaxy M51 is 213 grams, which is not a small amount.

The body of the smartphone is plastic and has a coating that makes it slippery. Therefore, we recommend that you use it with a case. There are no criticisms of the quality of workmanship. Samsung Galaxy M51 is available in two colors - black and blue. There is nothing on the back panel except a camera unit. The cameras protrude slightly above the surface, but this does not prevent you from leaving the device on the back of the table.

The bezels around the display are thin, but not as thin as modern flagships.


The smartphone is equipped with a quality Super AMOLED+ display with a diagonal of 6.7 inches and a resolution of 2400x1080 pixels. The screen impresses with nice colors, especially if you use the "Natural Colors" mode. Then the range becomes a little warmer and more comfortable for the eyes. We recommend another mode - "Saturated colors". It is traditional for matrices with organic diodes that the black color is as deep as possible. You will also like the viewing angles.

A bonus is the presence of the Always-on function, which allows you to visualize valuable information on the display and use it whenever you want, without having to turn on the device.


Samsung Galaxy M51 is based on a Qualcomm Snapdragon 730 processor - an octa-core chip with a maximum clock speed of 2.2 GHz. As a graphics processor we see Adreno 618. Depending on the modification, you can choose between 6/8 GB of RAM and 128 GB of internal storage. You can expand the latter with a memory card that has a separate slot.

This Samsung model works with the Android 10 operating system and One UI 2 interface.


The rear camera of the Samsung Galaxy M51 is quadruple. It consists of a main 64 MP module with an aperture of f / 1.8, a 12 MP ultra-wide module with an aperture of f / 2.2 and two 5 MP sensors - one of them, charged with the task of taking macro photos, and the other - to measure the depth.

The main camera takes very good pictures in natural light, the quality of which decreases when these conditions worsen. Then the contours become slightly blurred, noises appear. Video recording with the Samsung Galaxy M51 has a maximum resolution of 4K at a rate of 30 frames per second. The lack of optical stabilization is noticeable.

Autonomous work

We come to the key feature of the Samsung Galaxy M51 - the battery with enviable capacity. This device has an economical processor, which allows the charge not to run out in one day. To achieve this, you have to do your best - for example, to play games without interruption. Putting them aside, a standard mode of use with conversations, listening to music, surfing the Internet and social networks, you can count on two days of battery life.

If you watch YouTube videos at medium screen brightness, the Samsung Galaxy M51 will need to recharge in about a day.

How long does it take to recharge a 7000 mAh battery? Samsung has thought about this and has provided a charger with a power of 25 W. So in 30 minutes you provide 28% of the charge, and in an hour - up to 58%. It takes up to 2 hours to fully recharge from 10 to 100%.

An important advantage of the Samsung Galaxy M51 is the support of reverse charging, which allows you to charge other devices.


Samsung Galaxy M51 is a rare find on the market. It is difficult to find another smartphone with such a battery capacity and such a well-known manufacturer. In it almost everything is at a high level - display, camera, battery life and more. You may have some reservations only about its sound quality. The speed of the fingerprint scanner makes a pleasant impression.
