Samsung Galaxy M31 Review (2026) – Massive Battery, Super AMOLED Display & Reliable All-Round Performance
Samsung Galaxy M31 may not be the newest smartphone in the market, but even in 2026, it remains a popular and trusted choice among users who value long battery life, a vibrant AMOLED display, and dependable everyday performance. Originally launched as a battery-focused mid-range phone, the Galaxy M31 continues to attract students, office users, and budget-conscious buyers who want a reliable Samsung smartphone without spending too much.
In this detailed review, we’ll explore the design, display, performance, camera quality, battery life, software experience, pros & cons, and help you decide whether the Samsung Galaxy M31 is still worth buying today.
Design & Build Quality – Simple, Practical & Comfortable
The Samsung Galaxy M31 features a clean and minimal design with a glossy polycarbonate back. While it doesn’t feel premium like glass-back phones, the build quality is solid and durable, which is ideal for long-term daily use.
The phone is slightly thick and heavy, mainly due to its massive battery, but Samsung has balanced the weight well. The curved edges make it comfortable to hold, even during long calls or extended video watching sessions.
Available in attractive color options such as Ocean Blue, Space Black, and Red, the Galaxy M31 looks decent and modern, even by today’s standards.
Display – Super AMOLED is a Big Highlight
One of the strongest reasons to buy the Samsung Galaxy M31 is its 6.4-inch Full HD+ Super AMOLED display.
Display Specifications:
- Screen Size: 6.4 inches
- Resolution: Full HD+ (1080 × 2340 pixels)
- Panel Type: Super AMOLED
The display delivers excellent color accuracy, deep blacks, and sharp text, making it perfect for:
- Watching YouTube, Netflix, and Amazon Prime
- Browsing social media
- Reading articles and eBooks
Even though it has a standard 60Hz refresh rate, the AMOLED panel still feels smooth and visually pleasing. Outdoor visibility is good, and the screen performs well under sunlight.
For users who prioritize display quality over high refresh rates, the Galaxy M31 still outperforms many budget phones with LCD panels.
Performance – Smooth for Daily Use
The Samsung Galaxy M31 is powered by the Exynos 9611 processor, paired with:
- 6GB RAM + 64GB storage
- 6GB RAM + 128GB storage
For everyday usage, the phone performs smoothly and reliably. Tasks like:
- WhatsApp, Instagram, Facebook
- Web browsing and emails
- Video streaming
- Online classes and office apps
run without noticeable lag.
Light to moderate gaming (such as Subway Surfers, Free Fire, or casual games) works well. However, heavy games like BGMI or Call of Duty may require lower graphics settings for a smoother experience.
There’s also microSD card support, allowing you to expand storage easily, a big plus for users who store lots of photos and videos.
Camera Performance – Still Good for Everyday Photography
The Samsung Galaxy M31 comes with a quad-camera setup, which was impressive at the time of launch and still holds up for daily photography.
Rear Camera Setup:
- 64MP primary camera
- 8MP ultra-wide camera
- 5MP macro camera
- 5MP depth sensor
Front Camera:
- 32MP selfie camera
Rear Camera Quality
The 64MP main sensor captures sharp, detailed photos in good lighting conditions with natural colors. The ultra-wide camera is useful for landscapes and group photos, while the macro camera allows close-up shots.
Portrait photos come out well with decent background blur, although edge detection is average compared to newer phones.
Selfie Camera
The 32MP front camera is one of the best features of the Galaxy M31. It captures clear, detailed selfies and works great for video calls, online meetings, and social media uploads.
Video recording supports 4K at 30fps, which is still impressive in this price range.
Battery Life – A True Battery Champion
Battery life is where the Samsung Galaxy M31 truly shines.
Battery Details:
- Battery Capacity: 6000mAh
- Charging Support: 15W fast charging
With moderate usage, the Galaxy M31 can easily last:
- 2 full days for normal users
- 1.5 days even with heavy use
Whether you’re streaming videos, attending online classes, or browsing social media, battery anxiety is almost non-existent.
Charging speed is not the fastest by today’s standards, but considering the massive battery size, it’s acceptable. This phone is perfect for users who hate charging their phone frequently.

Samsung’s One UI is known for:
