Comparison review
Apple iPhone 8 is much better than the Galaxy A21, having an 85 score against 76.1. Apple iPhone 8's design is way lighter and just a bit thinner than the Galaxy A21, although it was released 3 years before. The iPhone 8 counts with a sharper screen than Samsung Galaxy A21, because although it has a way smaller display and a quite lower 750 x 1334px resolution, it also counts with a little bit higher pixel number in each inch in the display.
The iPhone 8 has a little better processing power than Galaxy A21, because although it has 1 GB less RAM memory and an inferior number of cores (although faster), it also counts with a 64-bit processor. The Apple iPhone 8 counts with a way bigger memory capacity for applications, games, photos and videos than Samsung Galaxy A21, because although it has no SD memory slot, it also counts with 224 GB more internal storage.
Galaxy A21 counts with a much longer battery lifetime than iPhone 8, because it has a 120% greater battery size. The iPhone 8 has just a bit better camera than Galaxy A21, because although it has a back camera with a much worse 12 megapixels resolution, and they both have the same diafragm aperture, the iPhone 8 also counts with a larger sensor which offers a higher image and video quality and a lot higher video definition.
Although iPhone 8 is a better device, it costs a lot more than the Samsung Galaxy A21, and it doesn't have such a good relation between it's price and quality as the Samsung Galaxy A21. If you prefer to save some money, you can get the Samsung Galaxy A21, giving up a couple features and specs, but you will get the most out of your budget.
