Comparison review

The Samsung Galaxy S21 is slightly better than Galaxy S6, having a 91.8 score against 87.3. Samsung Galaxy S21 is a way newer device than the Galaxy S6, although it's somewhat heavier and somewhat thicker. Both devices we are comparing here use Android OS, but the Samsung Galaxy S21 has a more recent 11 version and Galaxy S6 has Android 5.0, giving you a lot of extra features.

The Samsung Galaxy S6 features a little bit better looking screen than Galaxy S21, because although it has a bit smaller display, it also counts with a higher pixels count per screen inch and a higher resolution of 2560 x 1440. The Galaxy S6 has a bit better processing power than Galaxy S21, because although it has lesser RAM, and they both have 8 cpu cores, the Galaxy S6 also counts with a 64-bits processing unit and a graphics processing unit.

The Galaxy S21 takes just a bit better photographs and videos than Galaxy S6, because although it has a much worse resolution back camera, it also counts with a larger camera aperture, a way better video resolution and a much larger back-facing camera sensor providing a way higher image quality.

Galaxy S21's memory capacity to install applications and games is just as good as Galaxy S6's one, they have exactly the same internal storage capacity. Samsung Galaxy S21 has a really longer battery life than Samsung Galaxy S6, because it has a 4000mAh battery capacity.

Although Galaxy S21 is a better device, it costs a lot more money than Galaxy S6, and it doesn't have such a good relation between it's price and quality as Galaxy S6. If you are trying to save some dollars, you can get the Galaxy S6, and give up a few features and specs, but you'll get the most out of your money.
