Samsung Galaxy M21 128GB Expert Review Summary
Expert Rating:
![Kshitij Pujari]()
Verdict
It`s hard not to be too overly critical for smartphones costing less than Rs 15,000, but the intense competition of features at affordable pricing makes me question the Galaxy M21. It seems now that check-marking just the basics is not going to cut it in the budget segment for Samsung when the likes of Realme and Xiaomi have absolutely packed their competitive devices up to the brim with features. That said, the massive battery is clearly the highlights, and that`s where the Galaxy M21 delivers.
Pros
- Vivid and colour accurate display
- Long-lasting battery
- Decent day-time photography
Cons
- Higher refresh rate would have been nice
- Dated waterdrop notch design
- Slow charging speed
Design and display
+
As you would expect from an affordable phone, the Galaxy M21 has skimmed on physical aesthetics to make a durable device. The body and frame of the M21 are made from polycarbonate which does give out the glossy look of glass but is not as brittle. The curved back panel makes for an easy fit in the hand, although that is true for quite a few budget phones. The black colour variant I have received for my review doesn't show any fingerprints unless you shine a light on it. It does scratch very easily, with my review unit showing signs of use after just a couple of hours of playing with it.

The camera system on the M21 is almost the same as that of the Galaxy M31 (review) but with the absence of the macro lens. There's a 48MP primary snapper on the M21 in a triple-camera layout with the other two being an 8MP ultra-wide lens and a 5MP depth sensor.

Performance and software

The 10nm-based Exynos 9611 powers the Galaxy M21, which is the same SoC found inside the more expensive Galaxy M31. While there is technically nothing wrong with this chipset, there is a discernible amount of lag that I noticed during normal day-to-day activities. There was a small lag between clicking a photo and then previewing it, and this lag was more pronounced when viewing 48MP photos. If I had more than 5 tabs opened up in Chrome, there was a delay in opening more tabs and in general if multiple heavy apps were open in the background, I could feel a noticeable lag when opening more apps. You could say that I'm nitpicking but I'm used to smooth performance on the likes of the Realme 6 (review) or even the Redmi Note 9 Pro (review), which use the MediaTek G90T and Snapdragon 720G respectively. The M21 variant which I have received happens to have 4GB of RAM, although you can upgrade to a 6GB version for Rs 15,499.

Battery
+
It wouldn't be a stretch to say that the Galaxy M21 possibly offers the best battery life you could get on an affordable smartphone. The gigantic 6,000mAh powerhouse pushes through one day of usage easily and nears on completing two days before the battery gives up. Our standard battery test which involves running a video on loop with half brightness and volume saw the phone last nearly 30 hours. About an hour of PUBG Mobile drained the phone off just 12 percent battery which is quite phenomenal in my opinion. The only gripe is the 15W charging which takes more than 2 full hours to completely juice the phone up.
