Comparison review

The Galaxy S6 Edge is better than the Galaxy A21, with an 85.7 score against 76.1. Both phones we compare here include Android OS (operating system), but the Galaxy S6 Edge has the older 5.0 version and Galaxy A21 has Android 10. Despite of the fact that Galaxy S6 Edge is noticeably older than Galaxy A21, it's body is somewhat thinner and noticeably lighter.

Galaxy S6 Edge has an incredibly better display than Galaxy A21, because although it has a really smaller screen, it also counts with a much higher 2560 x 1440 resolution and a much greater pixels count per screen inch. Galaxy S6 Edge counts with a slightly better memory to store more games and applications than Galaxy A21, because although it has no external memory card slot, it also counts with 128 GB internal storage.

Samsung Galaxy S6 Edge has just a little better performance than Samsung Galaxy A21, and although they both have the same number of cores and 3 GB of RAM memory, the Samsung Galaxy S6 Edge also has an extra GPU and a 64-bit CPU. The Samsung Galaxy A21 counts with a really longer battery life than Galaxy S6 Edge, because it has 4000mAh of battery capacity.

Galaxy A21 takes better videos and photos than Samsung Galaxy S6 Edge, because although it has a tinier sensor taking less light and washed colors, and they both have a same resolution back camera, the same (Full HD) video resolution and the same video frame rates, the Galaxy A21 also counts with a larger diafragm aperture to take better low-light captures and video.

Although Samsung Galaxy S6 Edge is a better device, it is a lot more expensive than the Galaxy A21, and it doesn't have such a good relation between it's price and quality as Galaxy A21. So if you want that extra specs and features, you can buy the Samsung Galaxy S6 Edge, else you can save some money and get the Galaxy A21, letting go a couple specifications.
