Our Hands-On Take:

I myself bought this phone in 2024. I have used this phone for around 2 years for regular tasks like social media, streaming, and photo capturing. The 6.4-inch Super AMOLED display is really amazing at this price segment. But it is not smooth while playing heavy games. I recommend it for regular users who need a better display and longer battery life.

Battery Life and Charging

Strong battery life is a wonderful feature of the Galaxy A31 phone. It has a 5,000 mAh battery with a 15W fast charger. The backup of 17 hours and 18 minutes was recorded in PhoneYear’s battery drain test. It gets completely charged within 2 hours and 22 minutes using a USB Type-C cable. The battery lasts for the whole day at moderate use.

• Real-world battery test proves over 17 hours of backup
• 15W fast charger completes 100% within 2.5 hours
• Universally compatible USB Type-C

MediaTek Helio Performance

The MediaTek Helio P65 Octa-Core processor and 6GB RAM run the Samsung Galaxy A31. It runs smoothly for video streaming, browsing, and social media. This phone loses performance with heavy games like Call of Duty and PUBG Mobile. The fingerprint sensor, which is under the screen, works more slowly in comparison to side sensors in other phones.

Quad Camera Setup

Samsung Galaxy A31 has a four-camera setup. The main camera is 48MP, an ultra-wide 8MP, a 5MP depth camera, and a 5MP macro camera. With these cameras, you can capture stunning and sharp pictures in broad daylight. The portrait pictures are super amazing with this camera setup. If you enjoy mobile photography, pairing your phone with the Eloies Jaguar 3-Way Pan Head Tripod review can help capture steadier photos and videos. 

But this camera setup doesn’t have a dedicated night mode, which affects the picture quality in low light. The selfie camera of 20MP captures detailed pictures in daylight only.

• Portrait mode: Perfect pictures with a blurred background in daylight.
• Video quality: highest 1080p from both rear and front, but lacks Electronic Image Stabilisation

A31 Samsung Display Quality

The A31 Samsung series phone has a 16.26 cm (6.4-inches) full HD and Super AMOLED infinity U screen. With a resolution of 2400 x 1080 pixels and 412 PPI have 16M display colours. The screen-to-body ratio of 84% makes it a great for browsing and streaming online. Gorilla Glass 3 adds a cherry on the cake in protection and scratch resistance.

The refresh rate of 60Hz is a drawback because other brands offer more than 80 Hz of refresh rate now.

Pros and Cons

Pros	Cons
Super AMOLED display is rare at this price	No dedicated night mode, weak low-light camera
A 5000 mAh battery, real-world backup of 17+ hours	The Helio P65 chipset is not designed for heavy gamers
Samsung Pay and NFC support make the Samsung Galaxy A31 reliable	Under display fingerprint works more slowly than side scanners
3.5mm headphone jack and Dolby Atmos audio	No EIS (electronic image stabilisation) results in video instability for vloggers
Samsung Knox fingerprint sensor for security	60Hz refresh rate when other phones offer around 90Hz at this price segment

Final Verdict

The Samsung Galaxy A31 review helps make the final decision. Although it is a perfect choice as a regular smartphone, not designed for gamers. The long battery life, NFC support, 6.4-inch Super AMOLED screen, and Samsung Knox under-display fingerprint prove it a reliable deal. 

However, it isn’t for high gaming or has a night mode. It is a perfect deal for social media users and students under 20,000/-.

Buy it if you:

• Want an amazing display for browsing and video streaming.
• Trust Samsung Pay and NFC for tap payments
• Need a long-lasting battery with a single charge

Skip it if you:

• Like gaming heavy games such as Call of Duty, PUBG Mobile, or BGMI daily.
• Expect excellent night or low-light photography.
