The Galaxy A51 is just a bit better than the Xperia 5, having an 85.5 score against 81. The Galaxy A51 construction is a little thinner but a little heavier than the Xperia 5, and both were released with only a couple months difference. Sony Xperia 5 has a bit superior processor than Galaxy A51, and although they both have a Octa-Core processing unit, the Sony Xperia 5 also has 2 GB more RAM memory.
The Xperia 5 counts with a bit sharper screen than Galaxy A51, because although it has a little smaller display, it also counts with a little higher pixels density and a quite better 1080 x 2520 resolution. The Xperia 5's memory to install games and applications is very similar to the Galaxy A51 one, both of them have a slot for external memory cards that allows a maximum of 512 GB and equal 128 GB internal memory capacity.
Galaxy A51 has superior battery lifetime than Sony Xperia 5, because it has a 27 percent larger battery capacity. The Galaxy A51 captures much clearer pictures and videos than Xperia 5, because although it has a smaller diafragm aperture, and they both have the same video resolution and the same video frame rate, the Galaxy A51 also counts with a camera in the back with much more mega pixels and a way bigger sensor which offers a lot higher photo and video quality.
The Galaxy A51 not only is the best phones of the ones we compare here, but it's also a bargain compared to others, which makes it an easy decision.
