The M31 isn’t exactly the most eye-catching stunning looking phone but it looks decent and what really good in this design is the form factor. It’s a 6000 mAh battery in there and considering that this is a fairly lightweight compact and comfortable phone to use also the phone has a physical fingerprint scanner which is kind of getting rare now but since it’s a physical fingerprint scanner it is fast and accurate. The M31 comes with Super AMOLED display in this price range and it’s sharp and the colors look nice so watching shows and movies on this display was a good experience.

If you are wondering about any ads in the one UI on the Galaxy M31 it will not get any ads on the phone and that’s probably you can skip them during the starting setup process.

The Redmi Note 9 Pro brings a slightly more premium design into and has the triple slot for two SIM cards and a micro SD slot. The usual buttons, headphone jack, single speaker, and the USB-C port on the bottom. The Redmi Note 9 Pro comes with a 6.67-inch full HD plus IPS LCD display and it’s a nice display but it’s your regular 60 Hertz display. The display is well it feels kind of short-handed nobody wanted the specs the Redmi Note 9 Pro does bring in a new chipset but it isn’t exactly an upgrade.

Both come with a single speaker which gets decently loud and it’s fairly clear so yeah it’s very similar to other phones in this price range. It’s placed on the right side so when you are gaming the sound does not get blocked.

This is a 6000 mAh battery so the battery performance is pretty good and you don’t have to worry about battery life at all with the M31. When it comes to charging the 15-watt fast charger in the box takes around to ask a fully charged this phone which is well the price would pay for the humongous battery overall the entire one is impressive on the battery.

The battery which is actually an upgrade Redmi has bundled an 18-watt fast charger in the box. The faster charger would be nice to charge the big 5020 mAH battery.

Samsung Galaxy M31

The phone that brings 4 major highlights the cameras which are really good, the battery which lasts really long, the AMOLED display which looks really nice and lastly the Samsung branding. These are the things that matter to you that the Galaxy M31 is for you wouldn’t be disappointed. However, if high-end gaming or processing power is a priority then the M31 is probably not for you and you should check out other options.

Xiaomi Redmi Note 9 Pro

The Redmi Note 9 Pro is a phone that brings some good changes to the new design, center punch hole on the front is nice the bigger battery is pretty awesome, the 720G chipset, and the cameras. The higher refresh rate and Amoled display would be a way better. Redmi at least wants 27-watt charger would have been nicer also no HD on Netflix and prime video is kind of a big issue.
