Hardly any smartphone can offer a longer battery life than the Samsung Galaxy M51

The Samsung Galaxy M51 offers a very long battery life but is otherwise a rather average mid-range smartphone.

Samsung's large Galaxy M51 mid-range phone brings a huge battery but otherwise presents itself a bit stuffy. We tested for whom it still might be worthwhile, and here is an overview of our results.

Did you ever hear the name Doogee, Blackview, or Ulefone? Those Chinese manufacturers that are rather exotic for us here are the largest competitors of the Samsung Galaxy M51 if you consider the battery life. This is because Samsung has equipped its mid-range smartphone with a huge 7000-mAh battery, thus achieving runtimes beyond 25 hours in our WLAN test.

Sure, an Ulefone Power 5 can even last significantly longer, but it is a ruggedized smartphone with the corresponding design, which is bulkier and significantly heavier than Samsung's Galaxy smartphone. Among the regular smartphones, the Galaxy M51 is uncontested, since most smartphones in this price class only bring a battery capacity between 3500 and 4000 mAh, which is only slightly more than half on average.

Besides this extremely long battery life, is the Galaxy M51 worth a closer look? Well, first you should be aware that the Samsung smartphone does not set any new standards in the mid-range, if you ignore the battery life. The performance, case design, cameras, WLAN speeds, speaker quality – all that is rather average for a mid-range smartphone that costs between 350 and 400 Euros (~$412 - 471). Those who look for a 5G-capable mid-range phone will also be disappointed.

On the other hand, the Galaxy M51 does not have any grave weaknesses, except for one: Under maximum load, the smartphone heats up a lot and also throttles its performance significantly under longer loads. However, those who don't want to use their smartphone for constant gaming will only rarely notice anything about this. 

If you want to find out more about the Galaxy smartphone and are looking for a more in-depth analysis and test results of the smartphone, we recommend our review of the Samsung Galaxy M51.

When I was 12, the first computer came into the house and immediately I started tinkering around, taking it apart, getting new parts and replacing them - after all, there always had to be enough power for the current games. When I came to Notebookcheck in 2009, I was passionate about testing gaming notebooks. Since 2012, my attention has been focused on smartphones, tablets and future technologies.
