Comparison review
The Galaxy S21 has an overall score of 91.8, which is a little bit better than Galaxy Note9's score of 87.1. The Galaxy S21 is a incredibly newer phone, and it's also lighter and somewhat thinner than Galaxy Note9. The Galaxy S21 counts with a little more vivid display than Galaxy Note9, although it has a little bit lower pixels density, a way worse 1080 x 2400 resolution and a little bit smaller screen.
Samsung Galaxy Note9 and Samsung Galaxy S21 both feature incredibly similar processing units, and although the Samsung Galaxy Note9 has less RAM memory, they both have 8 cpu cores. Samsung Galaxy Note9 counts with a much better storage to install games and applications than Galaxy S21, and although they both have the same internal memory capacity, the Samsung Galaxy Note9 also has a slot for an SD memory card that holds a maximum of 512 GB.
The Samsung Galaxy Note9 features a battery life that is very similar to the battery lifetime in Galaxy S21. The Galaxy S21 takes a little bit better videos and photos than Galaxy Note9, because although it has a tinier aperture which is not nice for capturing images or video in low-light situations, and they both have a 12 MP back facing camera, the Galaxy S21 also counts with a lot bigger camera sensor which gives a way higher photo and video quality and a much higher 7680x4320 video resolution.
Although Galaxy S21 is a better device, it costs a lot more than the Galaxy Note9, and it doesn't have such a good quality/price relation as Galaxy Note9. If you are trying to save some dollars, you can buy the Galaxy Note9, letting go a couple features, but you will get the most out of your money.
