iPhone 12 vs Samsung S21 Comparison

iPhone 12 vs Samsung S21

It's hard to choose between these two high-end smartphones. They're priced almost identically, but they have other things in common, such as their size, screen quality and 5G compatibility. To decide between them, you need to look at their specific features.

Samsung S21: a screen with an adaptive refresh rate

The screens of these two smartphones, although slightly different, offer similar qualities. 

The iPhone 12 screen is a 6.1-inch OLED display with a 2532x1170 resolution. The Samsung S21 screen is a 6.2-inch AMOLED display with a 2400x1080 resolution. 

The Samsung S21 does stand out when it comes to refresh rate though. It offers an adaptive screen, meaning it can automatically adapt to the application you are using. This way, you preserve battery life without ever losing quality.

Another difference is that its screen uses a punch-hole to house the front-facing camera. On the iPhone 12, the notch is larger as it also houses facial recognition sensors; the Samsung S21 only has a fingerprint sensor.

iPhone 12: better battery life and charging

The Samsung S21 has a very modern design, but the iPhone 12 is still the leader in terms of charging technology.

The iPhone 12 was the first Apple smartphone to feature MagSafe, wireless charging which is made more efficient thanks to precise magnetic alignment.

iPhone 12 vs Samsung S21 size comparison

The iPhone 12 has a 6.1-inch screen, measures 146.7 x 71.5 x 7.4mm and weighs 174g. 

The Samsung S21 has a 6.2-inch screen, measures 151.7 x 71.2 x 7.9mm and weighs 172g. 

Nearly identical dimensions on paper. In hand, the iPhone 12 feels a bit wider -- it being a little smaller otherwise isn't very noticeable.

iPhone 12 vs S21: conclusion

It's really hard to tell the difference between the Samsung S21 and the iPhone 12, as their qualities and performance are so similar.

Both cameras perform well. However, unlike the Samsung S21, the iPhone 12 does not have a 3x telephoto lens. Both chips are fast. However, the iPhone 12 is the only one to use an Ultra Wideband chip for improved location accuracy. 

Ultimately, most people make a decision based on their operating systems. With Apple, you get iOS, which is very fluid and easy to use. You are also guaranteed to get the latest updates as soon as they become available. With Samsung, you can count on the latest versions of Android, since the manufacturer assures that its smartphones will be able to enjoy at least 3 major updates.
