Samsung Galaxy S21 vs Samsung Galaxy S10


With the Samsung Galaxy S21, the South Korean giant made an interesting turn to the left. For the first time in the history of the Galaxy S line with simple numbers, Samsung has taken its foot off the pedal and focused a little more on value.

It’s ideal for anyone looking for a classic flagship at a slightly lower price. But the question arises: How much upgrade does the Samsung Galaxy S21 cost compared to the Samsung Galaxy S10?

Two generations may have been removed from the S21, but the 10th Anniversary Galaxy S10 was built at a time when Samsung was launching (almost) everything except 5G in its signature model.
By the way, how does the Samsung Galaxy S10 5G fit into all of that? All of these and other questions are answered in the following function.

Samsung Galaxy S21 vs. Samsung Galaxy S10 Price and Availability

The Samsung Galaxy S21 hit stores on January 29, 2021 and was priced at $ 799 / £ 769 / AU $ 1,249 for the 128GB model. Rather unusual for the smartphone market, this was no more expensive than the introductory price of the Galaxy S20 before.

The Samsung Galaxy S10 landed on March 8, 2019. When it was launched, the 128GB model started at $ 749 / £ 669 / AU $ 1,149, which, unlike the Galaxy S21, was more expensive than its direct predecessor, the Galaxy S9. There was also a 512GB model for $ 1,149 / £ 999 / AU $ 1,699.

That was year zero for 5G phones. Therefore, a separate Galaxy S10 5G model was shipped in June 2019 to accompany the launch of the first 5G networks in the USA and Great Britain. Starting price for this model was $ 1,299 / £ 1099 (about AU $ 1,850) for the 256GB version and $ 1,399 (about £ 1,100, AU $ 1,990) for the 512GB version.

None of these models are sold as new through Samsung in the UK or US. However, you may find a brand new device via the usual third-party routes. At the time of writing, Amazon UK was selling a new 4G model for £ 498 while Amazon US was selling the same model for $ 575.


It’s interesting to compare the designs of these two phones. On the one hand, the Samsung Galaxy S21 is the newest and therefore coolest design. On the flip side, the Galaxy S10 likely feels more premium if it hits a more aggressive price tag with the Galaxy S21.
To satisfy its (relatively) lower price tag, the Samsung Galaxy S21 uses a “Glasstic” material for its back, which is essentially a mix of glass and plastic. But you probably guessed it from the name.

It doesn’t look as big as the Galaxy S10, which is combined with a classic combination of glass surfaces and aluminum housing. However, the S21’s matte finish is designed to remove fingerprints, and the metallic edges on the outside of the device restore a sense of class.

The S21 definitely looks great, especially with Samsung’s new color options (Phantom Gray, Phantom White, Phantom Pink, and Phantom Violet) and the matte finish. Maybe we’re a little premature here, but the phone’s distinctive “Contour Cut Camera” module looks instantly iconic, plunging into the device’s bezel from one angle and rising loudly and proudly from another angle.

Overall, we would prefer the distinctive design of the S21 to the confident and monotonous design of the S10 every day. It may come in attractive flamingo pink, prism black, prism blue, prism white, canary yellow, and prism green tones – some of which have a delightfully shimmering effect – but its matte horizontal camera setup looks more vanilla.

On the front, the S10 follows Samsung’s old way of thinking about curved screens. That sounds great (there are practically no side bezels here), but it also poses some practical problems, such as: B. incorrect pressing and annoying visual distortions.

The Galaxy S21 thankfully smooths the display. It doesn’t look as elegant as its predecessor, but this makes it a bit more user-friendly.
Both phones come with perforated selfie cameras, but the Galaxy S21 places them in the center while the Galaxy S10 shifts them to the right. The Galaxy S10 5G expands the camera module itself to a diamond shape that is more intrusive.

In terms of size, the Galaxy S10 comes in two configurations: 149.9 x 70.4 x 7.8mm for the 4G model and 162.6 x 77.1 x 7.9mm for the Galaxy S10 5G. The Galaxy S21 shares the difference to 151.7 x 71.2 x 7.9 mm, but is much closer to the size of the Galaxy S10 4G. This also applies to the weight: the Galaxy S10 with 157 g, the Galaxy S10 5G with a meaty 198 g and the Galaxy S21 with 169 g.


The Samsung Galaxy S21 and Samsung Galaxy S10 share similarly sized displays: 6.2 inches for the S21, 6.1 inches for the S10.Aside from that, and the fact that they both use Samsung’s unmatched AMOLED panel technology, there are some interesting differences here. Would you be surprised to learn that the Galaxy S10’s display is the sharper of the two, and somehow? It assumes a resolution of 1440 x 3040 or QHD +, while the newer S21 gets by with a simple resolution of 1080 x 2400 / FHD +.

While the old phone can get a lot sharper, the new phone can go a lot faster. With an adaptive refresh rate of 120Hz, the Galaxy S21’s content can keep flowing, literally doubling the smoothness of the Galaxy S10.

Overall, we tend to view this as a useful tradeoff, especially with the ripple effect on battery life. Sure, the Galaxy S21 Ultra can handle both QHD and 120 Hz at the same time, but it has a much larger display and battery and costs a lot more.

However, we prefer the Galaxy S20 option or / or option for both the S21 and S10.
We should also mention the screen on the S10 5G, which at 6.7 inches is significantly larger than the other two. Apart from the size, it is identical to the Galaxy S10 in terms of resolution and display properties.

And what display properties apply to all three models? Samsung makes the best displays in the business and offers these AMOLED beauties to many of its competitors. While the S21 is the best-calibrated screen here, all three phones benefit from HDR10 + support, vivid (but customizable) colors, deep blacks, and strong peak brightness.

At the time the S10 was released, it was named the most color-accurate smartphone display of all time. This applies to every subsequent Galaxy S display, even if the Galaxy S21 Ultra is currently technically the champion. The plain Galaxy S is no longer getting you the absolute best from Samsung that can get stuck on some people’s minds.

Every phone has an ultrasonic fingerprint sensor hidden under the display. Neither of these are fast, but the Galaxy S21 speeds things up and expands the interface by a whopping 70%, resulting in a much shorter authentication experience than the Galaxy S10.


Both telephones are equipped with camera systems with three lenses as standard. However, the fine details reveal some key differences that give the S21 a clear advantage.

The Samsung Galaxy S21 is equipped with a 12-megapixel main unit as well as a 64-megapixel telephoto lens and a 12-megapixel wide-angle lens. There is a 10 megapixel selfie camera on the front.

The Samsung Galaxy S10 is equipped with a 12MP normal lens, a 12MP telephoto lens and a 16MP wide-angle lens. As with the S21, there is a 10-megapixel selfie camera on the front.

Interestingly, the Galaxy S10 5G model is slightly different from its 4G sibling. It’s a four-camera setup with the same sensors as the 4G model plus a time-of-flight (ToF) sensor for accurate depth sensing and improved AR.

We said the S10 5G has a longer and more intrusive display notch, and that’s because it also includes a ToF camera on the front. Not only does this strengthen your selfie portraits, but it also allows you to capture Live Focus selfie videos. It’s pretty impressive.

For general recordings, the Galaxy S21’s camera is by far the best. This despite the fact that the hardware is practically identical to the previous S20.

Interestingly, some of the hardware on the S21 appears to be a downgrade from the S10. In addition to the low-resolution ultra-wide-angle sensor, there is the slim double aperture 1: 1.5 + 1: 2.4 of the S10, which can change depending on the lighting conditions. The main gate of the S21 is locked in the middle with a fixed aperture of 1: 1.8.

However, if you take a closer look at the spec sheet, you’ll find that the Galaxy S21 captures larger pixels – 1.8 microns instead of the S10’s 1.4 microns. Thanks to this and the improved algorithms from Samsung, the S21 takes significantly better pictures in poor lighting conditions.

The much denser 64 megapixel telephoto lens of the Galaxy S21 enables the capture of highly effective optical 3x hybrid zoom shots.

Samsung has also made some notable video enhancements, including Director’s View, which lets you see all three rear lenses live at the same time and then switch between them. Vlogger View allows you to record video from the front and rear cameras at the same time. The single take funct

Battery life

The Samsung Galaxy S21 initially seems to be the clear winner in terms of endurance. At 4000 mAh, the battery is much larger than the 3400 mAh of the Galaxy S10.Add in the Galaxy S21’s more efficient Exynos / Snapdragon processor and the fact that its display is only 1080p versus 1440p and victory is apparently assured.

That’s not how it works. The 120 Hz refresh rate of the S21 display makes up for the situation considerably, despite its variable nature, which means it can drop down to 1 Hz if necessary.In general, we’ve found that the Galaxy S21 can easily last a full day on a single charge. However, when you hit your phone’s GPS signal and other power hungry features, you can be exhausted right before bed.

This all sounds eerily similar to our experience with the Galaxy S10, which would have been a regular occurrence at the end of a day with moderate use if there was around 20% left in the tank.It’s better to understand which one is best. Basically, these are two phones all day, as long as you don’t hit them with constant media consumption or keep Pokemon Go running all the time.

One of the things that has the potential to degrade the Galaxy S21’s battery a bit faster is 5G connectivity, which the stock Galaxy S10 doesn’t have to deal with. There’s a reason the Galaxy S10 5G increases the battery capacity up to 4,500 mAh. Even then, with the upgraded model’s large QHD + display and less efficient processor, we could only get through a day of moderate use on a single charge.

Both the Galaxy S21 and the Galaxy S10 5G support wired charging with 25 W, which is not particularly fast on a large scale. Not when rivals like Oppo hit 65W. The standard Galaxy S10 is even slower at 15 W.However, all three phones support similar 15W wireless charging and 4.5W wireless charging, which is a decent arrangement.
