Comparison review
The Samsung Galaxy A51 has a global score of 85.5, which is slightly better than the Huawei Mate 30's score of 84. Even when Samsung Galaxy A51 and Huawei Mate 30 were only released 3 months apart, Samsung Galaxy A51 is lighter and just a bit thinner. Both phones we compare here come with Android OS, but Samsung Galaxy A51 has a newer 11 version while Huawei Mate 30 has Android 10 version, so it provides you a lot of extra features.
Galaxy A51 and Huawei Mate 30 both have very similar displays, because although the Huawei Mate 30 has a little bit lower 1080 x 2340 resolution and a quite inferior number of pixels per display inch, it also counts with a little bit larger display. The Galaxy A51 counts with a much greater storage capacity for games and applications than Huawei Mate 30, and although they both have the same 128 GB internal memory, the Galaxy A51 also has a slot for external memory cards that supports up to 512 GB.
Huawei Mate 30 features a bit more powerful processor than Samsung Galaxy A51, and although they both have the same number of cores, the Huawei Mate 30 also has a greater amount of RAM memory. Huawei Mate 30 has a bit better camera than Galaxy A51, because although it has a lower 3840x2160 video resolution and a back-facing camera with a worse resolution, it also counts with a larger camera aperture for better photos and video in poorly lited environments and a lot bigger camera sensor.
The Huawei Mate 30 has just a bit better battery lifetime than Galaxy A51, because it has a 4200mAh battery size against 4000mAh.
