Galaxy M21 to Buy: Price, Specs & Should You in 2025

Few phones have sparked as much debate among budget buyers as the Samsung Galaxy M21. Launched in India in March 2020, it promised a massive 6000 mAh battery and a bright Super AMOLED display at a competitive price.

Released: 2020 · Battery: 6000 mAh · Display: 6.4‑inch Super AMOLED · Processor: Exynos 9611 · RAM: 4 GB / 6 GB · Starting price (India): ₹12,999 (2020)

Eleven core specifications, one standout feature: the 6000 mAh battery that made the M21 a battery champion.

Is the Galaxy M21 a good phone?

Performance and daily use

• Powered by the Exynos 9611 (TechRadar), the M21 handles messaging, calls, and social media without stutter. Heavy gaming, however, pushes the chipset to its limits — frame‑rate dips in titles like PUBG are common.

Camera quality

• The 48 MP main sensor (Gadgets 360) captures decent detail in daylight, but low‑light shots appear soft. The 8 MP ultrawide adds versatility, though its dynamic range is narrow.

Battery endurance

• With a 6000 mAh cell (TechRadar), the M21 easily lasts two days on a single charge for moderate users. The 15 W charger is slow by modern standards – a full top‑up takes nearly three hours.

The implication: for someone who prioritises battery life and a good screen over raw performance, the M21 still delivers. Gamers and camera enthusiasts will want to look elsewhere.

How much is the Galaxy M21?

Original launch price

• The original M21 launched at ₹12,999 for the 4 GB + 64 GB variant (Gadgets 360). The 2021 Edition was introduced at ₹12,499 (TechRadar).

Current market price (new and refurbished)

• New units are scarce in 2025. Some Indian retailers like Croma list a 4 GB variant at ₹11,994 (Gadgets 360). Refurbished models on Back Market hover around $100 – $150 depending on condition.
• Price aggregators show conflicting figures – 91mobiles lists ₹14,999 (91mobiles) while Cashify’s page inconsistently quotes both ₹6,699 and ₹13,499 (Cashify).

Price in different regions

• Outside India, the M21 was never widely available. Most international listings are from third‑party sellers on eBay or refurbished specialists.

What this means: paying more than ₹12,000 for a new M21 in 2025 is hard to justify. Refurbished units under ₹9,000 make sense for buyers on a tight budget.

What is the difference between Samsung Galaxy M11 and M21?

Two budget phones from the same series, but the M21 outclasses the M11 in almost every department.

The pattern: the M21 delivers a vivid OLED screen, a punchier chipset, and a much larger battery. Even five years later, it beats the M11 on every spec that matters for daily use.

Is Samsung A15 better than M21 5G?

Processor and 5G support

• The M21 uses the Exynos 9611 and lacks 5G connectivity (Gadgets 360). The Galaxy A15 5G runs on a MediaTek Dimensity 6100+ and includes 5G (according to Samsung’s product specifications).

Display and software updates

• The A15 5G features a 90 Hz display, while the M21 is stuck at 60 Hz. The A15 is also newer and will receive longer software support.

Camera and battery

• The M21’s 48 MP camera arguably takes better stills than the A15’s 50 MP sensor in good light. But the A15 charges faster (25 W) and is more future‑proof.

The trade‑off: the M21 still wins on battery capacity (6000 vs 5000 mAh) and display quality (Super AMOLED vs LCD). For buyers who need 5G and a smoother screen, the A15 5G is the better pick.

How old is the Galaxy M21?

Launch timeline

• Released in March 2020 (Gadgets 360). A 2021 Edition with the same chipset but minor tweaks arrived in July 2021 (TechRadar).

Software update cycle

• The M21 received Android 12 in 2022 and Android 13 in 2023 (Gadgets 360). No further OS upgrades are planned. Security patches may continue sporadically.

Current relevance

• At five years old, the M21 feels dated. It lacks 5G, the 60 Hz screen looks last‑gen, and the processor struggles with modern apps. But for a secondary phone or a media consumption device, it still holds up.

Why this matters: if software updates are a priority, the M21 has reached the end of its lifecycle. Buyers should factor this into a purchase decision. For a look at how software updates affect device longevity, see our iOS 26 public beta guide.

Summary: Should you buy the Galaxy M21 in 2025?

The Galaxy M21 was a brilliant device for its time, and its battery and display still hold up. But the phone has reached the end of its software support cycle, lacks 5G, and its processor struggles with modern apps. For an Indian buyer looking at the sub‑₹12,000 segment, the Galaxy A15 5G offers a better long‑term investment with faster charging and future‑proof connectivity – or save more and step up to the Galaxy M35 5G. For the Indian buyer on a tight budget who can find a refurbished M21 under ₹8,000, the choice is clear: grab it as a secondary media device, or wait for a newer alternative.
