About the Samsung Galaxy M12

The Galaxy M12 was Samsung's attempt to win the budget end of the market on stamina alone, and on that count it worked. A 6,000mAh cell in a phone this cheap makes two days of light use realistic rather than optimistic, although the 15W charging means refilling it is an overnight job. Samsung also did something unusual for the money by fitting a 90Hz screen, so scrolling feels smoother than most rivals at the price. The trade-off is resolution: the panel is HD+ LCD, so text and video look noticeably softer than on the AMOLED phones Xiaomi was selling for similar money. The Exynos 850 is built for efficiency rather than speed, and it handles messaging, streaming and social apps without complaint while struggling with demanding 3D games. The 48MP main camera is capable in daylight and unremarkable once the light drops; the macro and depth sensors alongside it add very little. Today the M12 is a phone you choose for battery life, a headphone jack and a microSD slot rather than for performance, and its software support window has long since closed.

Frequently asked questions

Is the Samsung Galaxy M12 worth buying?
The Samsung Galaxy M12 is worth considering only if battery life is your priority and you are happy with a phone from 2021 that no longer receives software or security updates. Its 6,000mAh battery and 90Hz screen still stand out at the budget end, but the HD+ LCD panel and Exynos 850 chip feel dated. Newer Galaxy A-series models offer sharper screens and current software support.
How long does the Samsung Galaxy M12 battery last?
The Galaxy M12 carries a 6,000mAh battery, one of the largest Samsung has fitted to a budget phone. With light to moderate use it comfortably clears two days between charges. Charging is limited to 15W, so a full top-up takes a couple of hours.
Does the Samsung Galaxy M12 have 5G?
No, the Galaxy M12 is a 4G-only phone. The Exynos 850 chipset has no 5G modem, so it connects over 4G LTE on all UK networks. If you want 5G at a similar size and price, look at Samsung's 5G-badged A-series models instead.
Does the Samsung Galaxy M12 have a headphone jack and microSD slot?
Yes to both. The Galaxy M12 keeps a 3.5mm headphone jack for wired earphones and has a dedicated microSD card slot for expanding storage. That combination is increasingly rare, and it is one of the phone's genuine practical advantages.
Is the Samsung Galaxy M12 camera good?
The 48MP main camera produces usable, reasonably detailed shots in good daylight, which is what matters most at this price. Low-light performance is weak, with visible noise and slow shutter response. The 5MP ultrawide is passable and the 2MP macro and depth sensors contribute little of value.
How does the Samsung Galaxy M12 compare to the Galaxy A12?
The M12 and A12 share a body and a 48MP quad camera, but the M12 is the better buy of the two on paper: it has a 6,000mAh battery against the A12's 5,000mAh, a 90Hz refresh rate instead of 60Hz, and Samsung's Exynos 850 rather than the MediaTek Helio P35. The A12 is lighter at 205g versus 212g and is the more widely stocked of the pair in the UK.
Does the Samsung Galaxy M12 still get software updates?
No. The M12 shipped on Android 11 with One UI Core 3.1 and its update window has now ended, so it no longer receives new Android versions or security patches. That is the strongest argument for choosing a newer budget Galaxy if you plan to keep the phone for several years.
