One of the most packed Samsung devices in the M31 series, the Samsung Galaxy M31s had a massive 6,000mAh battery, a 4 camera setup of 64MP and a super AMOLED screen. We will be discussing all the Samsung Galaxy M31s specs, the price, design, display, performance, camera performance, battery life, software, the good and bad, and how it compares with the regular Samsung Galaxy M31 and if it’s a good choice for 2026. This guide will help you understand all things you need to know if you are looking for this phone as a budget phone, an upgrade or just curious.

Samsung Company Overview 

Samsung Electronics of South Korea is one of the world’s biggest technology companies, and a leading player in the global smartphone market. The Galaxy range of products covers all segments, targeting flagship buyers with the S and Z series, mid-range users with the A series, and budget consumers such as those in India with the M series, focusing on battery life and camera specs. The M series includes the Galaxy M31s, which aims at the value-minded mid-range market. Samsung also makes displays, semiconductors and home appliances, and is one of the few companies to make both the hardware and the components that power their own products.

Price and Availability

The Samsung Galaxy M31s’s pricing in India came out to be around ₹19,999 to ₹22,999 at launch, making it a mid-range device to purchase. As of 2026, you cannot buy the phone new through official sales channels, so buyers mainly find it on the second-hand or refurbished market at a fraction of its original price.

Where to Buy

The Samsung M31s is no longer available for purchase new, and is no longer found on official stores. At this time a refurbished and second-hand market is the best bet. Cashify and Refit Global have quality checks and warranties of 6 to 12 months for their certified refurbished units. Occasional third-party sellers are still available on Amazon India and Flipkart, but there are vast differences in available stock and prices.

Users often choose OLX and Facebook Marketplace for peer-to-peer deals, but they should check the battery and screen condition before buying because these platforms do not provide a warranty. The price is generally between ₹4,000 and ₹12,000 per piece, depending on the condition and the storage period. When buying batteries, always check the battery health – a battery that is 5+ years old, with 6,000mAh capacity, may not be capable of holding the same level of charge as it once did.

Design and Build

The M31s will come with an Infinity-O screen with a punch-hole camera, a polycarbonate glossy rear, and a fingerprint sensor in the power button on the side. It was also available in a range of colours, such as Mirage Blue and Mirage Black, and had a design language that was very similar to the standard Galaxy M31.

Display

This phone has a 6.5-inch Full HD+ Super AMOLED display with 1080 x 2400 resolution, which is covered with Corning Gorilla Glass 3. The AMOLED panel provides a good level of blacks and colors, which was ideal for streaming and gaming back then but it’s not the high refresh rate (60Hz) they have today.

Performance and Processor

Samsung powers the Galaxy M31s with its own Exynos 9611 chipset that is built on an octa-core processor, featuring 4×2.3GHz Cortex-A73 + 4×1.7GHz Cortex-A53 CPUs and a Mali-G72 MP3 GPU. It comes with either 6GB or 8GB of RAM. At launch this was a solid mid-range processor for everyday multitasking and casual use, but has become outdated by newer mid-range chips.

Camera Performance

Galaxy M31s has a quad camera system, comprising of a 64MP primary sensor with f/1.8 aperture, a 12MP ultra-wide lens (f/2.2, 123° wide-angle), a 5MP macro sensor, and a 5MP depth sensor for portraiture. It can shoot 4k video at 30 frames per second and features Samsung’s “Single Take” mode which allows for multiple photo and video formats in a single shot. The front camera is 32MP which can take selfies and has support for Live Focus which will blur the background.

Battery and Charging

One of the M31s’ key highlights at launch was its 6,000mAh battery, which supports 25W Super Fast Charging. The phone also supports reverse charging, allowing users to charge other compatible devices using the M31s. This proved to be one of the most durable phones in its category, as it was able to last for an entire day of intensive use.

Software and Updates

It comes preloaded with Android 10 and One UI 2.0. It got a few Android and Samsung One UI version updates after that, depending on the region and Samsung’s update policy at the time, until it was kicked off the end of software support. The phone won’t get security updates after 2026, so that’s something to consider when purchasing.

Pros and Cons

Pros:

• It features a huge 6,000mAh battery paired with quick charging.
• Great Colorful Super AMOLED Display
• 4 camera sensor with versatile mode.
• Excellent quality, for its class.

Cons:

• Modern by today’s standards, it is based on the dated Exynos 9611 chipset.
• No display with a high refresh rate.
• Software updates are no longer available.
• Currently not available in most markets as new product

Should Samsung Galaxy M31s be bought in 2026?

Since Samsung launched the Galaxy M31s in 2020, users no longer consider it a primary smartphone in 2026. Its outdated chipset and lack of ongoing software and security updates make it less suitable for daily use. Budget-conscious buyers may still find it a good low-cost secondary device, or even acquire one on a second-hand basis, for its remarkable battery life. Today, newer middle-range devices with faster chipsets and higher refresh-rate screens are typically a better investment for the same price.

Samsung Galaxy M31s vs Samsung Galaxy M31: What’s the Real Difference?

Many people mistakenly think the M31s is a more expensive version of the standard M31 because Samsung launched it only a few months after the M31. Here’s a clear comparison of the two models.

Conclusion

When the Samsung Galaxy M31s debuted in 2020, it quickly gained the reputation of the battery and camera-centric mid-range that offered great value. It doesn’t have top-notch specs anymore in 2026, with its old hardware design and the absence of software support, but it is a decent comparison for Samsung’s M-series and its 64MP camera with the 6,000mAh battery.
