Performance

At the core of the Samsung Galaxy M31 lies an 8-core Exynos 9611, consisting of 4x2.3 GHz + 4x1.7 GHz. The graphics core is a Mali-G72 MP3. The smartphone is available in 6 GB RAM and 128 GB flash memory modification with an option to expand up to 512 GB with a microSD memory card. If we have to draw a parallel with the Samsung Galaxy M30s, here the RAM is 2 GB more. This will definitely be to the advantage of the Samsung Galaxy M31's performance. 

The combination of a mid-range chipset with a not bad stock of RAM guarantee this model a decent performance. It performs beautifully in everyday tasks including mobile gaming.

The Galaxy M31 is equipped with a quad camera with flash. The flagship sensor is 64 MP with f/1.8 aperture and works with Quad Pixel technology. Here, 4 pixels are combined into one to produce more light. This brings the actual resolution down to 16 MP. Of course, you can also shoot with all 64 MP.

The selfie camera is graced with a 32-megapixel module and can shoot video up to 4K resolution. 

Autonomous operation

The battery capacity is 6000 mAh Samsung Galaxy M31. We can define it as a key trump of this model. It guarantees full autonomous work up to 1.5-2 days. Of course, if you get into more mobile games and use other heavy applications, you will need to recharge earlier. Samsung has provided fast charging technology, and the charger goes in the package. 

Conclusion

The Samsung Galaxy M31 is an excellent smartphone with well-rounded capabilities, nice performance, a quality display, and satisfactory autonomy. As a con, we can point out the casing, which will easily leave fingerprints on it if you don't wear a case.
