After the success achieved in 2019 with its Galaxy M and Galaxy A lines, Samsung returns to the fray with one of the models with the best balance between specifications and low price. The successor to the Galaxy M20 arrives by replicating the most basic strategy, updating many of its components throughout the entire specification sheet.

The Galaxy M21 recovers the claim of a “monstrous” battery, according to Samsung’s own words in an advertisement that has so far been focused on India, one of the manufacturer’s largest markets. It comes with a better screen, bigger battery, more cameras and more memory optionsLet’s take a closer look.

Galaxy M21: autonomy by flag, transversal evolution


The Galaxy M21 repeats a virtually identical design compared to the previous generation, with a slightly larger screen but now making the leap to Amoled technology that Samsung has been using for a decade. More vibrant colors and a notch on the top will be the most visual features of this generation.

Inside we do see a new processor now more efficient and powerful and shared with the somewhat more powerful lines of the house, such as the Galaxy A51. This Exynos 9611 in 10 nanometers is accompanied by a memory configuration that will now be double: 4/64 GB and 8/128 GB.


There are big changes to your camera as well, now including a triplicate sensor. To the ultra wide angle is added a depth sensor of 5 MP. Your main camera now has a 48 MP sensor, in addition to an improvement in fisheye resolution up to 8MP. Finally, the front camera also goes up to 20 MP.

It is in its battery where we see that Samsung redoubles efforts to try to make the autonomy of this series its characteristic by flag. As the capacity of practically the terminals grows, the Galaxy A21 does the same, reaching up to 6,000 mAh, nevertheless maintaining its load at 15 W.


Finally, we see that the Galaxy M21 recovers a latest version of Wi-Fi standard, with support for ac networks, and we see how the Android version is also updated, with the last one available now: Android 10.
