So how does it feel like putting a large 6,000 mAh battery in a phone like this? We think some may find the Galaxy M31 a little hefty but for us we are used to the heft. And because it is a smaller phone with 6.4-inch display, the phone is a little thick too. We can manage the bulk but putting it in a pocket will definitely bulge. Overall, it is a pretty well built phone. A little hardware tour – fingerprint scanner is at the back, volume rockers on the right, power button on the left, 3.5mm headset jack with the USB Type C port and speaker are at the bottom.

Good thing Samsung puts its signature AMOLED display on this phone. As expected the 6.4-inch display is bright, colorful and vivid. Watching movies and playing games has been always enjoyable in an AMOLED panel.


Like we said before, Samsung’s One UI 2.0 is an improvement over previous Samsung skins. It has less bloatware and redundant apps. The problem with One UI is it does not get timely updates like major Android updates especially for Samsung’s midrange offerings. Nonetheless, it is still an improvement as security updates are more timely now.

The Exynos 9611, the chipset that powers the Galaxy M31 is an aging chipset. Another thing, Exynos chipsets are not quite there yet as its Qualcomm competition. This doesn’t mean this chipset is not capable. In fact, during our two-week review period, we never experienced any lags and slowdowns. As for gaming, it can run games such as Mobile Legends smoothly. But we prefer Gardenscapes and Homescapes as game of choice.


Samsung also made some upgrades in the camera department. The Galaxy M31 has a 64MP main camera. It shoots 16MP by default and photos are surprisingly good actually. The 8MP ultrawide camera takes also good photos with less distortions. We are not impressed with the 5MP macro camera but photos are not bad but they lack vibrancy.


The 6,000 mAh battery is pretty big power mill. On our video loop test, we managed only to drop the battery from 100% to 40% with 8 hours straight of Netflix, You Tube and IWant. Our eyes already got tired of watching. That battery is very impressive! On standby time we managed to last about week on idle but with WiFi on and with 70% battery left. It is very safe to say that this is a 3 to 4-day phone with mixed moderate to heavy use.

As for the connectivity, WiFi is quite impressive. 4G/LTE speeds are within normal range and calls are clear with no issues. Signal stability is also good.


The star of the show here is really the battery. The Samsung Galaxy M31 is perfect for someone who hates getting glued to a power bank or a power socket. This is perfect for those who is always on the move a lot and travels a lot. Apart from that, this phone is also great for multimedia consumption. With a large battery, watching those hit Korean dramas online will be an uninterrupted experience. Plus, you get a good display and a decent camera system. We give the Samsung Galaxy M31 a two thumbs up recommendation. 🙂
