Comparison review
Samsung Galaxy Note9 has a global score of 87.1, which is a little bit better than Galaxy A51's global score of 85.5. Despite being the best we are comparing here, it must be told that it is also an older, somewhat heavier and somewhat thicker phone. Galaxy Note9 counts with a little bit better hardware performance than Samsung Galaxy A51, and although they both have the same number of cores, the Galaxy Note9 also has 2 GB more RAM.
The Galaxy Note9 counts with a slightly better looking display than Galaxy A51, because although it has a quite smaller display, it also counts with more pixels per screen inch and a higher resolution of 1440 x 2960. Galaxy A51 captures better photos and videos than Galaxy Note9, because although it has a much tinier aperture which is not good for shooting images and videos in low light environments and slower video frame rate, and they both have the same 3840x2160 (4K) video quality, the Galaxy A51 also counts with a way bigger sensor and a back-facing camera with a way higher resolution.
Galaxy Note9's memory capacity to install applications and games or saving photos and videos is just as good as the Galaxy A51 one, both of them have a SD memory slot that holds up to 512 GB and exactly the same 128 GB internal storage capacity. Samsung Galaxy Note9 has a battery life that's very similar to Samsung Galaxy A51's battery life.
Although Galaxy Note9 is a better device, it costs a lot more than Galaxy A51, and it doesn't have such a good quality/price relation as the Galaxy A51. So if you need that extra specs and features, you can buy Galaxy Note9, otherwise you can save some dollars and buy the Galaxy A51, giving up a couple features and specs.
