Samsung Galaxy S22 vs Galaxy S21
What are the differences between the Samsung Galaxy S22 and its predecessor, the Galaxy S21? And is it worth spending a bit more to get the S22?

The Galaxy S22 has a few advantages: it has a faster chip, an improved camera system and it switches to a more premium glass back design. But at the same time, it is a slightly smaller phone, and while many people will appreciate the more compact size that also results in a slightly reduced battery life.

So... which one should you go for? We dive in detail exploring all the differences between the Galaxy S22 and S21, so read on.

Design and display

The Galaxy S22 takes the idea of a compact phone and truly lives up to it. While the Galaxy S21 featured a 6.2-inch display and did not quite feel like a true "mini" phone, the newer Galaxy S22 embraces the compact idea with a 6.1" screen that is considerably less tall.

For years, Samsung has been making increasingly larger phones, and this is the company's first time reversing course towards a more pocketable and compact handset. In fact, historically speaking, the S22 is only slightly taller than the tiny Galaxy S10e that launched way back in 2019!

Here's how the Galaxy S22 dimensions compare to recent Samsung flagships:

Galaxy S22 — 146 x 70.5 x 7.6mm
Galaxy S21 — 151.7 x 71.2 x 7.9mm
Galaxy S20 — 151.7 x 69.1 x 7.9mm
Galaxy S10 — 149.9 x 70.4 x 7.8mm
Galaxy S10e — 142.2 x 69.9 x 7.9mm

And the new Galaxy S22 also weighs a tiny bit less than the S21 (167g versus 171g).

The rest of the S22 looks quite familiar: you get a flat screen and a punch hole design on the front. A nice little touch is that you get identical bezels around the screen for the first time ever on a Samsung phone. Nice! Previous Galaxy phones used to have a bit of a "chin", or a wider bottom border, but no more. That might seem like a small thing, but it is something only Apple and Google have actually made, and it just looks cool.

We also have the latest Dynamic AMOLED screen tech with more vibrant colors and higher peak brightness of 1,500 nits compared to the 1,300 nits maximum on the S21 (keep in mind that these numbers are measured at a mostly dark screen, while our measurements above differ because we use 100% white content when we measure max brightness). Of course both phones support a 10-120Hz adaptive refresh rate for buttery smooth scrolling in apps.

Security on both phones is handled via an in-screen fingerprint scanner of the ultrasonic type. We did not notice any difference in performance, both are quite accurate and fast enough. Both phones also support 2D image-based face recognition via the front camera.


The Galaxy S22 comes with all new processors powering the show, and just like in previous years, the US model is equipped with Qualcomm's Snapdragon 8 Gen 1 chip, while international models gets the Samsung-made Exynos 2200 processor.

The Galaxy S21, on its part, has the Snapdragon 888 in the US, while international models feature the Exynos 2100 chip. We have the Exynos model of both phones for this comparison.

Below, you can find benchmarks of the new Snapdragon 8 Gen 1 and how its performance compares to the previous, Snapdragon 888:

While CPU performance testing does not seem to show a gigantic improvement in performance, the GPU does, and that means that gamers will be in for a treat.

In the GFXBench 5 Aztec Ruins offscreen test, the Snapdragon 8 Gen 1 scored 45 frames per second. Other phones were far behind, and for example, the Galaxy S21 Ultra only showed up with 19fps on the same test, which means the Snapdragon 8 Gen 1 deliver more than twice as much.

There is not much of a change in RAM or storage. The S22 comes with 8GB of RAM and 128GB of storage in the base model for $800, and just $50 on top buys you an 8GB/256GB model, which seems like a no-brainer upgrade.

We should also mention here that Samsung no longer supports microSD cards on either phone.


Just looking at the camera setup on the back, it's hard to tell the S22 apart from the S21, as both have similar-looking triple camera systems. But it's what inside those cameras that undergoes some changes.

So, we have triple cameras on both: wide, ultra-wide, and telephoto zoom cameras. Check out the table below with the detailed camera specifications:

The biggest change is the new 50MP main sensor on the S22, bigger than the previous model.

The telephoto camera which used to be a 64MP sensor that cropped in to zoom on the S21 is replaced with a native 3X zoom lens which promises cleaner zoomed in shots. There seem to be no changes in the hardware for the ultra-wide and the front cameras.

Take a look at some camera samples we shot on both phones:

During the day, the difference is subtle and both phones do a solid job with beautiful colors and plenty of dynamic range. The S22 tends to have slightly warmer colors, and the detail in the 3X zoom shots is definitely cleaner on the S22.

On the video front, Samsung is still one of few companies to support 8K video, and of course, you can record at lower resolutions like 4K60, 4K30, and 1080p on both phones as well.

Samsung also promises improved night time video recording and enhanced video stabilization that will work even at night.

Battery life and Charging

The biggest compromise Samsung had to make with this compact S22 is the smaller battery: you have a 3,700mAh battery vs 4,000mAh on the S21, which is a nearly 8% reduction in size. Not a small change for a phone that did not have a great battery life to begin with.

So can Samsung offset this smaller battery size with more power efficient chips and display technology?

We turn to our independent battery test to find out:

As you can see above, there is a slight drop in battery life, but the keyword here being slight as you get just 10 minutes more on our YouTube video streaming test with the S21. These two are quite similar in that regard.

On the charging front, both phones charge at up to 25W speeds, and don't forget that you don't get a charging brick in the box with either one. 

Both also support wireless charging with max speeds of up to 15W, as well as reverse wireless charging where your phone is able to act as a wireless power bank.

Specs Comparison

And here is a quick look at the specs on the Galaxy S22 vs Galaxy S21:

Good news is that Samsung has not changed prices and the Galaxy S22 still starts at $800 for the base model, while only $50 more buys you a 256GB storage model, which sounds like a no-brainer upgrade for heavier users.

Despite the smaller battery, we think that the more compact size and the improved cameras and faster performance make for an exciting S22 launch.

Should you upgrade if you already own the Galaxy S21? You don't need to as the differences are not that huge, but for those rocking older phones, the S22 shapes up as a great option.
