Samsung Galaxy M30s Review | Samsung's Value for Money Smartphone

Sabin Tamang 28 Oct, 2019

Samsung Galaxy M30s has got a few upgrades over its predecessor Galaxy M30 in the battery department, camera department and performance. But is it worth the purchase? This is our review of the Samsung Galaxy M30s as this phone is not just about the huge 6000 mAh battery as it has impressed me in many other aspects as well. 

Design and Build Quality

I expected it to be very bulky and uninspiring as phones with big batteries go but that was absolutely not the case. It's actually not very heavy and has good grip thanks to the curved sides and although it's made of plastic it does not feel that cheap.

On the front of the phone, Galaxy M30s features a 6.4-inch (2340 x 1080 pixels) Full HD+ Infinity-U Super AMOLED display with thin bezel a small u-shape, not on the top and a big bezel on the bottom. Unlike other mid-ranges out there, Samsung utilizes a Super AMOLED display instead of an IPS panel this means that you get superior quality than the IPS ones.

The colors contrast and brightness levels are great for the price and having used MI A3 and Realme 5 Pro, what I can certainly tell you is that the Samsung Galaxy M30s provide you a much better display and watching media on this screen is a great experience. However, what average here is the single firing speaker but Samsung has brought back the 3.5 mm.

Talking about biometrics, M30s also offers a fast fingerprint sensor and since I was used to using slow fingerprint sensors in the past, the faster fingerprint sensor on the m30 s is a welcome addition. There's also a not so reliable software-based face unlock, which is fairly accurate and fast as well.


Now talking about the inside of the phone you get Exynos 9611 chipset based on 10nm. The phone is available in two memory variants one with 4GB RAM and 64GB storage and the other with 6 GB of RAM and 128 GB storage. The 4GB RAM and 64GB variant is obviously the better value for money here so I would advise you to go with that.

Now talking about the Exynos 9611 chipset it's based on 10 NM and strangely it does not offer any improvements over its predecessor Exynos 9610 except this one supports higher megapixel cameras. Exynos 9611 chipset is a mid-range chipset and a fairly good one. The performance is good but I wouldn't say excellent having used a Note 8 Pro and Realme 5 pro, I can certainly say that it's not as smooth as them.

Samsung Galaxy M40s features one UI and it is still my favorite skin from multitasking trade to notifications panel to the Settings dashboard everything feels minimalistic. I also turn on the night mode because it does not save the battery but because I like it.

Talking about the gaming performance, the Mali-G72 MP3 GPU is averaged PUBGM runs at HD graphics and high frame rates by default but I had to either lower down the graphics or frame rates for starter feel the experience. Even the recently launched Call of Duty has stutters and lags in medium settings and is playable only in low settings.

Also after like 30 minutes of PUBGM and Call of Duty, I noticed some heating issues at the back of the device. So, yeah the galaxy M30s is not the best performing phone in this price range, especially for gaming. I would advise you to go with the Redmi note 8 pro that has a much superior Mediatek Helio G90T chipset.


The Samsung Galaxy M30s is Samsung’s first mid-range smartphone to feature 48-megapixel triple cameras. The phone features a 48 MP main sensor (wide) arranged in a vertical setup. The other two sensors are 8 MP (ultrawide, 123 degrees) sensor and 5 MP (depth sensor).

At first, I was very skeptical about the cameras of the M30s because the Galaxy M10 and the Galaxy M20 that we reviewed had very average cameras but this one actually has very good cameras. By default shoots in 12 megapixels however you can go in the camera setting here to change into the 48-megapixel mode. The 48 megapixel takes like 2 seconds to capture the images and has more details when compared to the 12-megapixel mode. The photos shot from a 12MP camera have very natural and good colors.

Details are also fine and the dynamic range is not bad either. The wide-angle images also share the same story. It has good colors and most importantly is natural like the primary images. It does not miss out on detail if you zoom in but that's expected of an 8-megapixel wide-angle shot. The 5-megapixel depth sensor also does a decent job in terms of portraits. Samsung has also included a night mode but it doesn't work well. It messes on the exposure and the images come out overexposed.

Talking about the front camera, Galaxy M30s features a 16MP sensor that captures some good selfies in a good light. The portrait mode also captures average photos and edge detection is also quite good.

For video recording, the Galaxy M30S records 1080p and 4k videos at 30fps and surprisingly there is no 60fps on both of them. The 1080p videos are stable with accurate color presentation excellent contrast and dynamic range. If you want more details you can shoot in 4k as there is no stabilization on 1080p. You can also use the ultra-wide-angle lens at 1080p for videos. There is also a super steady mode which is a cropped version of the ultra-wide-angle videos but is stable. There's also the usual 240 FPS slow-mo and 960fps super slow-mo options which do an ok job.

Some camera samples


Talking about the battery, Galaxy M30s is powered by a massive 6000 mAh battery. For me, it will last you for two days on moderate usage and if you are a heavy user who likes to game a lot and watch videos it will still give you a day of usage. A 15-watt fast charger comes in the box which can charge your phone from 0 to 100% in around 2 hours and 20 minutes.
