Samsung Galaxy A51 vs. Galaxy S10 – Which One Suits You Best?

Affordable smartphones are a pleasant advantage of living in 2021.

One such device is the Samsung Galaxy A51. It has an enormous HD screen and four-lens rear camera module. It has a $399 sticker price, making it a solid choice.

However, is it really the best choice when you compare it to its sibling, the Galaxy S10? Let’s see!

You’ll rapidly notice that the two devices are members of different classes, but the gap in price between the two may help you look past such minor differences.


The S10 has a 12MP wide-angle sensor, 16MP ultra-wide and 12MP telephoto lens, plus a 10MP selfie shooter.

The A51, on the other hand, has a 48MP main camera, 12MP ultra-wide, 5MP macro, and 5MP depth sensor.

Though on paper, the A51 would seem to be the better choice, the S10 takes better photos inarguably, but not by much.


The S10 has a stunning display – a 6.1″ Quad HD+ Dynamic AMOLED panel, but that is expectable for a device of that price range.

However, the A51’s 6.5″ Full HD+ panel returns pleasant images far superior to many devices of its price range.


If you are a regular user, the two devices will feel mostly the same.

However, if you are an intense multi-tasker or gamer, you will rapidly notice that the A51 is somewhat sluggish.

The S10 has twice the RAM and a more capable chipset.

Battery Life

This is one of the most important aspects for many smartphone buyers.

Both devices can last through an entire day.

They have similar talk time results of 21+ hours, while the A51 laster somewhat more when browsing and video playback thanks to its less power-hungry chipset.

Also, both devices feature fast charging.
