iPhone 13 Pro vs Samsung S21 Ultra Comparison

iPhone 13 Pro vs Samsung S21 Ultra

Sometimes it's hard to tell the difference between two smartphones when they're so good. This is the case between the iPhone 13 Pro and the Samsung S21 Ultra. These two recent models embody all the know-how of their respective manufacturers. Apple and Samsung have equipped their devices with brand-specific features that make them good smartphones. So which is the best for you? This guide should help you decide. 

iPhone 13 Pro, the fastest

The Samsung S21 Ultra is taller and slightly wider than the iPhone 13 Pro in terms of size. It's also easier to handle and hold. The iPhone 13 Pro makes up for its form factor in speed and performance thanks to its A15 Bionic chip and 6GB of RAM (Exynos 2100 processor and 12 or 16GB of RAM for the S21 Ultra, depending on the version). The S21 Ultra runs well, but it doesn't compete on these points technically speaking. The iPhone 13 Pro has an undeniable fluidity throughout daily use. However, the limits of this are only noticed on the most demanding games. For normal use, it is difficult to notice a difference between the two phones.

The iPhone 13 Pro will also have the advantage of receiving software updates for longer. Thanks to its high-end components, it is basically guaranteed to support at least 5 years of updates. This is not the case for the Samsung.

Samsung S21 Ultra, an exceptional zoom

It's hard to tell the two smartphones apart when it comes to photography. The iPhone 13 Pro has a triple 12 MP module with wide-angle, telephoto and x3 optical zoom. The Samsung S21 Ultra has a 108MP wide-angle lens, a 12MP ultra-wide-angle lens, a 10MP telephoto lens with x3 optical zoom and a second telephoto lens capable of x10 optical zoom. In both cases, you have one of the best cameras available in a smartphone, and the result is stellar photos.

Do you regularly play intensive mobile games? Then the iPhone 13 Pro is the best choice for you. For more traditional use, or to take advantage of the S21 Ultra's exceptional zoom, choose the Samsung.
