Design, Display, & Build

The Samsung Galaxy M51 is available in two colors and we got the Celestial Black variant to play around with. Talking about the design, the Galaxy M51 features a shiny back panel that looks like glass but it’s actually Glasstic. The device weighs 213 grams which is impressive because it packs a massive 7000 mAh battery. Devices like Redmi Note 9 Pro Max, Moto E7 Plus, and more that feature a 5000 mAh battery weighs more than 200grams so we were expecting the Galaxy M51 would be heavy but Samsung surely did a great job in managing the weight.

The Samsung Galaxy M51 feels premium when you hold it in your hands but the glasstic back panel on the device attracts a lot of fingerprints which makes it hard to use without a case. You get the camera module on the top left corner along with the Samsung branding at the bottom. You get a fingerprint scanner on the power button and volume buttons are also placed on the right. The fingerprint scanner works perfectly and unlocks the device within a second.

You also get a 3.5mm headphone jack, a USB Type-C port along with the speaker grill in the bottom. The sound output from the speakers on Samsung Galaxy M51 is not as good as it’s competitors but it gets the job done well. It also comes with support for Dolby Atmos and you can use that when you plug in your headphones for a better audio experience. You can use a MicroSD card for expanding the storage along with two SIM cards as it has a triple card slot on the left. Overall, the built quality is good and the device surely does impress when it comes to the design.

Samsung never disappoints when it comes to the Display and the same is the case with Samsung Galaxy M51. The Galaxy M51 features a stunning 6.7-inch Full HD+ Infinity-O Super AMOLED Plus display with a resolution of 2400 x 1080 pixels. It comes in a 20:9 aspect ratio and in addition to this, it is protected by Corning Gorilla Glass 3 on the top.

The display on the Galaxy M51 is amazing, You get vibrant and punchy colors along with nice deep blacks. It comes with 420 nits of peak brightness and thanks to that,  you never struggle to read text or use the smartphone even in the direct sunlight. The punch hole camera on the front doesn’t interfere with your full-screen experience and you get used to it easily. The viewing angles are great and you’ll definitely enjoy streaming your favorite TV Shows and Movies on this one.

Overall, the Display on the Galaxy M51 is best in this price range. However, the user experience would have gotten much better if Samsung ditched the 60Hz refresh rate and went with a 90Hz panel on this one.







User Interface and Software

Samsung Galaxy M51 runs on the latest OneUI 2.1 which is based on Android 10 and offers a lot of additional features. While usually a lot of mid-range smartphones from Samsung running OneUI often face some minor issues and problems with opening Apps the Galaxy M51 handles everything easily,

In our usage, the Galaxy M51 was able to handle every little thing we threw at it. There was no lag and the overall experience with the UI was smooth. It comes with a lot of bloatware however you can uninstall mostly every app you don’t need. It doesn’t have any Ads in the UI but the notifications from the Samsung Apps are really annoying and you’ll have to turn it off for a clean experience. The Apps load quickly and the animations are also smooth.

The device comes with Widevine L1 support which means that you’ll be able to enjoy your content in the best quality on Streaming services like Netflix and Amazon Prime. In addition to this, users can also enjoy HDR videos on YouTube thanks to its HDR10+ supported display.

Hardware, Performance, & Gaming

Samsung Galaxy M51 is powered by a Snapdragon 730G Processor which is further coupled with an Adreno 618 GPU. It comes with 6/8 GB of LPDDR4x RAM and 128 GB UFS 2.1 internal storage which is further expandable to 512GB via MicroSD card. Now the Snapdragon 730G is a pretty good chipset and it came out early this year. It feels good to see that Samsung finally ditched the Exynos Processor and went for the 730G on this one.

When compared with the 5G enabled Snapdragon 765G on OnePlus Nord the Galaxy M51 does score less in benchmarks and stuff but there is no difference in everyday usage. Apps load up quickly, multitasking can also be done without any issues. In addition to this, the Snapdragon 730G is built for gamers which means that you’ll be able to run most of the modern titles without any issues.

We tried playing Among Us, Call of Duty, and Standoff 2 on this one, and the performance was great. Call of Duty runs on High graphics without any issues however you may face some frame drops at the max supported settings after few hours of Gaming.

Battery Life

Samsung Galaxy M51 is the first smartphone that comes with a massive 7000 mAh battery which comes with support for 25W Fast Charging. It also supports reverse charging which means that you can use this smartphone as a personal power bank if you run out of battery on your secondary smartphone.

The battery life on this smartphone can go up to 3 days with a single charge but that highly depends on your usage. We were easily able to get 2 days of battery life after a single charge when we did common tasks like browsing through social media apps, watching YouTube videos, playing some games, and more. Throughout our usage, the device was on maximum brightness with Always-on display enabled.

The 25W fast charger comes bundled in the box and it takes about 2 hours to charge the device completely which is good considering its battery capacity. Overall, the battery life on the Samsung Galaxy M51 is the best that you can get in this price range and as of now, no smartphone in the market can offer you a 7000 mAh battery.


The Samsung Galaxy M51 is a bang for a buck. This is everything you need from a mid-range device that costs Rs.25,000. It has a stunning Super AMOLED Plus display and a massive 7000 mAh battery which none of the rivals are offering right now. In addition to this, Samsung has gone for Snapdragon 730G this time and thanks to that you get a major performance boost when compared to other mid-range devices by Samsung that comes with the Exynos chip.

Overall the device gives a tough competition to OnePlus Nord and even has better cameras when compared with it. If you are on a strict budget of Rs.25,000 then the Samsung Galaxy M51 is the perfect smartphone for you.
