Samsung Galaxy M51 review

Another day and one more Galaxy M sequence telephone has been launched by Samsung. By my estimation, we are actually seeing the sixth telephone within the lineup this 12 months, and with every mannequin, it appears that evidently the road between finances and mid-range phase is getting somewhat blurred. The Galaxy M sequence began off as a finances resolution to compete with Chinese rivals, however is now overlapping with the extra premium Galaxy A sequence by way of pricing, making the Samsung lineup a bit complicated. However, the corporate has made it a degree to retain the core M sequence values similar to strong construct high quality and an enormous battery. In reality, the Galaxy M51 is the primary smartphone in India to boast a battery rated at a minimum of 7,000mAh.

Samsung had introduced the Galaxy M51 final week for a beginning value of Rs 24,999 which places it within the OnePlus Nord (review), Redmi K20 Pro (review), and Realme X3 territory. The system additionally competes in-house with the Galaxy A51 (review), and Galaxy M31s (review) as nicely. With a whole lot of choices to select from, the Galaxy M51 has a degree to show that it will possibly punch above its weight class. Let’s discover out on this full review if the M51 has managed to try this.


What you get with the Galaxy M51 is exceptionally good battery life, in contrast to any telephone can provide at its value. On the aspect, you get respectable efficiency, cameras and an expansive show as nicely. An common consumer will fairly simply be happy with the M51 as a each day driver, however for a extra performance-loving viewers, the Realme X3 or the OnePlus Nord may be higher suited.

Design and show

  • Display: 6.7-inch FHD+
  • Refresh rate: 60Hz
  • Panel: Super AMOLED
  • Connectivity: USB Type-C

The Galaxy M51 is kind of probably the most important telephone within the M sequence that I’ve seen until now and in addition, understandably, the heaviest. It’s not day by day you get to check out a telephone with a 7,000mAh battery however I’m fairly impressed by how Samsung has saved the thickness of the M51 to about 9mm. Also at 213g, the M51 is usually a little weighty within the hand but it surely nonetheless has a cushty grip due to the curved again panel, a staple for smartphones these days. The physique is created from a polycarbonate ‘glastic’ materials which does make the system liable to scratches. However, the M51 doesn’t include a transparent silicone case, which is a bummer.

There is a side-mounted fingerprint sensor on the correct aspect of the telephone which doubles up as an influence button, and it is a function that has made its means on to a whole lot of smartphones as of late. As a matter of reality, I actually like this positioning as a result of it’s in an ideal spot for my thumb. For left-handed customers, the index finger ought to attain the sensor simply as nicely. There is the quantity rocker buttons current alongside the sensor and on the backside, you can find a Type-C port, a 3.5mm headphone jack, and a single speaker grille. The dual-SIM plus microSD card slot is current on the correct of the system. Samsung has supplied me with the Charcoal Black color variant for review, however I’ve to say it seems to be nearer to a silver-greyish color that may very conveniently act a part-time mirror due to its extraordinarily polished end. I do love a shiny look however I desire the type of matte-like end employed on the OnePlus Nord, which makes it straightforward to take product photographs and in addition avoids a whole lot of smudging.

A 6.7-inch Super AMOLED panel makes for an immersive viewing expertise on the Galaxy M51 and between the huge display dimension together with a weighty design, you’ll not be holding the telephone with one hand for very lengthy. This is an Infinity-O Panel, which is Samsung’s terminology for a punch-hole show. Other facets embrace an FHD+ decision, peak brightness of 420nits, and 20:9 side ratio. Samsung has lengthy perfected the artwork of a succesful show, be it any class of smartphones and it seeps into the M51 as nicely.

There will hardly be any distinction between the show high quality of the M31s and the M51, aside from the dimensions of the display. The M51’s panel has all some great benefits of being AMOLED similar to excellent viewing angles, practically zero color shift, deeply pronounced blacks and typically higher color replica than an LCD panel. Customisation choices embrace altering the color temperatures from a vibrant Vivid mode to a extra reasonable however barely uninteresting Normal mode. You additionally get the power to alter the theme to Dark Mode and in addition make use of a Blue Light filter. All in all a nicely rounded, A-grade show with zero complaints aside from the truth that it misses out on a excessive refresh rate. As for defense, the M51 has the older Corning Gorilla 3 for stopping injury to the display.


  • Rear cameras: 64MP main, 12MP ultra-wide, 5MP macro sensor and 5MP depth sensor
  • Front digicam: 32MP

The Galaxy M51 packs in the identical quad-camera {hardware} which is current on the M31s introduced just a few months again. There is the 64MP Sony IMX682 sensor supported by a 12MP ultra-wide lens together with twin 5MP cameras for depth sensing and macro photographs. While the {hardware} stays the identical, what has modified is the brand new ISP discovered on the M51’s Snapdragon 730G SoC versus the Exynos 9611 SoC. There’s a slight however noticeable change in picture high quality.

The fundamental sensor on the M31s gives punchy and contrasty pictures. On the M51, the pictures are barely extra enhanced in particulars and the saturation stage is toned down for a extra pure hue to the surroundings. Apart from that, autofocus on the M51 is sort of instantaneous which is kind of good to see particularly if you end up taking pictures a video. Overall the sensor will get in a whole lot of gentle and in addition has nice HDR capabilities which will be enhanced by the automated AI-scene detection. For additional detailing in a shot, you may go along with the UHD 64MP mode.

Apart from that, the ultra-wide, depth and macro sensors churned out photographs that have been additionally just like the M31s. The 123-degree subject of view will get in a whole lot of the topic into the body however has the standard warping on the edges. Portrait mode or, as Samsung calls it, Live Focus, works nicely with the devoted depth digicam however the acquainted issues of correct edge detection across the topic have nonetheless not been resolved. The macro sensor is of little utilization and when referred to as upon it doesn’t ship to its full potential. I might hardly name pictures from the macro sensor as ‘social media worthy’. At night time the digicam will utilise the AI-scene detection to robotically get in additional gentle in photographs. The devoted Night mode offers extra readability to photographs, fills in colors extra precisely and typically sharpens the deal with the topic. I stand by my assertion of getting your money’s price at night time pictures with the M51 as I had stated for the M31s.

On the entrance there’s a 32MP selfie shooter and it really works in addition to you’d anticipated it to. As with the M31s, you will notice the pixel-binning to get detailed 8MP photographs or you may shoot instantly in 32MP though there seems to be little or no distinction between the 2 modes. Samsung once more makes use of a whole lot of oversharpening of facial particulars however I’m pleased with the color alternative it employs in pores and skin tones. It additionally has the 4K video recording from the entrance of the telephone, one thing only a few telephones on this value can do.

Performance and software program

  • Chipset: Qualcomm Snapdragon 730G
  • RAM: 6GB and 8GB LPDDR4
  • Storage: 128GB, expandable to 512GB
  • Software: Android 10 with OneUI 2.0

Samsung has executed away with the Exynos 9611 (used within the Galaxy M31s, M31, M21, A51, M30s, A50s) and gone with the trusty Qualcomm Snapdragon 730G. Now it’s fairly clear that for its value vary and seeing what the competitors gives, the Galaxy M51 is just not profitable accolades by way of processing prowess. The OnePlus Nord gives the newer Snapdragon 765G SoC which amongst different issues can also be 5G-ready whereas the Realme X3 has final 12 months’s flagship Snapdragon 855+ SoC. Benchmark outcomes level in the direction of the identical with the M51 scoring decrease in all conventional exams similar to Geekbench, AnTuTu and PCMark when in comparison with the Nord or X3 Superzoom. However, it is a comparability made for energy customers who want to do intensive duties similar to heavy-duty gaming or video modifying on their smartphone.

The Galaxy M51 occurs to be glorious at multi-tasking, searching, navigation and the overall utilization is fluid and quick. This is clear when heavy apps similar to YouTube or Instagram are open within the background, and switching between is sort of seamless. There is not any delay within the shutter pace of the digicam or processing of pictures within the Gallery app. I’ve the 8GB RAM + 128GB model with me, though I might advocate the 6GB model of the system which sells for Rs 24,999. There can also be the choice to increase to 512GB utilizing a microSD card.

On the authentication entrance, the side-mounted fingerprint sensor is fast and responsive however I’ve observed that at occasions it takes just a few makes an attempt to register it. Apart from that, the face unlock is iffy in low lighting and even with the assisted lighting, I might not depend on the telephone to get my face proper. The bottom-firing speaker has no adjustments from the M31s that means it sounds fairly good for the value. Even so, it might be good to see stereo help. Samsung has graciously supplied Dolby Atmos by a pair of wired earphones/headphones so there’s that. Call and microphone high quality, like all the time, are up to speed.

Here once more, the OneUI 2.0 pores and skin, proprietary to Samsung, has come into play and brings with it Android 10. The software program side on M sequence telephones and typically most of Samsung telephones this 12 months has remained unchanged. I’ve lined the OneUI 2.0 pores and skin in better element throughout my review of the M31s and my colleague’s M31 review additionally talks about it in depth. In quick although, right here’s what you may anticipate: tons of customisation choices, refined settings menu and notification tray, some Samsung bloat, and a clean UI.


  • Capacity: 7,000mAh
  • Charging speeds: 25W quick cost
  • 0-50 %: 40 minutes

Ah, the pièce de résistance of all the M51 ensemble is undoubtedly its mind-boggling 7,000mAh battery that’s fairly actually the largest that I’ve seen on a smartphone in India. It shattered information for my commonplace smartphone battery take a look at, which includes operating a video at half brightness and quantity on a loop, by staying on for a file 36 hours. You’ve heard of a 1-day telephone or perhaps a 2-day telephone in excessive circumstances. The Galaxy M51 can push for an insane three days on a single cost should you hold the brightness of the system locked at half. It can do two days fairly simply should you solely watch a few hours of video streaming together with regular day-to-day utilization. For extra intensive duties similar to gaming, the telephone has the power to final all the day with out breaking a sweat, however will nonetheless want a cost solely by the subsequent day. In help for this mammoth battery is a 25W charging resolution which can juice up the system in about 2 hours. Like the M31s, there’s help for reverse wired charging for the reason that M51 is principally like an influence financial institution in itself.

Final Verdict

Like earlier iterations, the Galaxy M51 focuses on the core finances consumer expertise which calls for a stellar battery life and processing necessities that handle to get many of the work executed. Add to {that a} succesful digicam setup and a class-leading show, the Galaxy M51 makes for a luxurious alternative.

However, should you take into account the competitors on this phase, the OnePlus Nord gives a cleaner software program expertise and a quicker chipset. The Realme X3 additionally will get you a quicker expertise and a smoother 120Hz refresh rate panel. I assume the vital resolution to make whereas buying this system is whether or not you worth good battery life, respectable cameras and color correct show over facets like pure efficiency and excessive display refresh rate. Whatever be the case, the Galaxy M51 positively deserves a more in-depth second search for its humongous battery backup.
