Samsung Galaxy S21 vs. Xiaomi Mi 11 – Which One Is Worth Buying?

The Samsung Galaxy S21 And Xiaomi Mi 11 are some of the best Android phones of the moment.

They feature high-end capabilities at a reasonable price.

If you are looking for top-notch quality for your money, the Mi 11 is a very favorable choice. It is a fantastic performer, has a high-performance processor and when you analyze it down to tiny bits, it has better value for money.

However, the Mi 11 isn’t a good choice for everybody.

The S21 is a noticeably smaller phone, which is perfect for those who want to say goodbye to devices that pop out of their pockets.

Also, the S21’s camera packs some extra punch.

These are the main highlights of the two devices. Let’s see a more in-depth comparison.

Main Highlights

  • The construction of the Xiaomi Mi 11 is more premium thanks to its curved glass on the back and front.
  • The S21 is a device made for those who want to use the phone with a single hand.
  • The Xiaomi Mi 11’s Snapdragon core is often dubbed as a better processor than the S21’s Exynos chipset.
  • The S21 features a dedicated zoom lens, while the Xiaomi device depends on its high-resolution primary camera for zoom images.
  • Samsung’s ultra-wide and selfie cameras are better performers than those of the Xiaomi.

Hardware Specs

The S21 features a Samsung Exynos 2100 CPU, similar to that of the Galaxy S21 Ultra.

The Mi 11 features a Snapdragon 888, which is often referred to as the best Android processor available when the device was launched.

In terms of CPU, we believe that Xiaomi is the winner, as Qualcomm’s Snapdragon’s lineup is the overall better performer for gaming and energy efficiency.

However, for the regular user, the difference is barely noticeable at all. Both devices can handle today’s Android apps without any problem.

Storage And Pricing

The Mi 11 is the more affordable option here – It costs £649 with 128GB storage, or £699 with 256GB storage, while the S21 costs £769 for the 128GB version or £819 for the 256GB version.

However, if you are patient enough and search for a while, you can find the S21 for a more affordable price, close to that of the Mi 11.

Battery Life

Neither of the two devices is an impressive performer when it comes to battery life.

In daily usage, the autonomy of the two is comparable.

The S21 features a 4000mAh battery, which is adequate for its smaller size, while the bigger 4600mAh of the Mi11 are equivalently plentiful considering the device’s larger screen size.

However, in real-world conditions, the Mi 11 is the better choice thanks to its 55W charger that can get the device from 0% to full in less than an hour, while the S21 only supports 25W charging.

Display And Camera

The Mi11 features a 108MP primary camera, which, at first glance, sounds a lot better than the Galaxy S21’s MP camera/

However, when you analyze it closely, the S21’s module has a better ultra-wide camera, a more capable zoom, and a 64-MP sensor paired with a 1.1x lens for zoom shots.

Overall, the S21 feels more capable of taking breathtaking shots.

As for the display, this is the field that separates the two devices upfront.

The Mi 11 features a 6.81-inch screen, while the S21 has a smaller, 6.2-inch screen.

The Mi11 features a 3200 x 1440 pixel screen, while the S21 has a lower-res 2400 x 1080 pixel panel, which looks stunning thanks to its smaller size.

They are both OLED panels, providing fantastic contrast.
