Samsung Galaxy S21 Ultra review

The Galaxy S series debuted a little earlier last year than usual, with Samsung showing it recently in February, before the Mobile World Congress, which is held annually in Barcelona. However, this year the exhibition “moved” to the end of June, and the South Koreans decided to coincide with the release of their flagship to another major exhibition – CES 2021

Design and positioning

On the test, “RG” got a black device. The back surface of the device is matte. It does not collect fingerprints, and those who like to carry the device without a case will be happy. This solution worked well in the Note series: but if there was an exclusive bronze model, then in the S-series it applies to absolutely all colors – black, silver, blue, and bronze.

The camera block, although slightly protruding from the body, turned out to be neater than that of the S20 Ultra. The lenses themselves are slightly “recessed” – one can only applaud for this decision – the cameras will not collect dust from the surface where the user puts the smartphone. On the right side edge we found a place for the power button and volume rocker, on the left side edge there are no controls.

The SIM-card tray has moved to the lower side edge, the MicroSD memory card has been removed from it. This is a completely logical decision – the user can choose from three configurations – 128 GB, 256 GB, and 512 GB. The SIM-card is now one and this is also understandable – the S21 Ultra supports eSIM technology. It uses 5g Technology.

There is another hole next to the tray – a microphone. Some media wrote that users may confuse the microphone with the hole for the SIM card tray, but it is rather difficult to do this – firstly, the hole for opening the tray is to the left and there is a border of the tray itself, and the microphone hole is located separately on the bottom edge. Then everything is standard – a USB C connector and six cutouts for the speaker. Another microphone is on top.

Positioning the S21 Ultra is pretty simple – it’s one of the most powerful Android smartphones today. It is suitable for those who need the latest technology.


The diagonal of the device screen is 6.8 inches, the screen resolution is QHD – 3200 x 1440 pixels. The default mode is 2400 x 1800 pixels, but you can safely turn on QHD. The resolution has almost no effect on battery life.

An important change from its predecessor is that the adaptive screen frequency of 120 Hz is now included in the highest resolution. This means that the gadget adapts to the tasks that are performed on it. If the user plays PUBG or World Of Tanks, the smartphone will turn on 120Hz mode. And if a static image is shown from the Always-on Display mode, then 10 Hz is enough there. In this case, the display can be adapted for yourself – to make the tones warmer or colder, depending on how you like it.


The S21 Ultra has 4 cameras – an ultra-wide-angle 12MP with f / 2.2 aperture, a 108-megapixel wide-angle module with f / 1.8 aperture, and two telephoto lenses – one optical three times and the other optical ten times. The smartphone now has the ability to shoot video in 4K and 60 frames per second on all cameras, including the main and front ones.

A trick has appeared, which video bloggers will surely appreciate – you can shoot what is happening on the main camera and at the same time shoot yourself. We also improved the night mode – photos in low light are better than its predecessor. The selfie camera has also been updated with a 40-megapixel resolution with f / 2.2 aperture. Sample photos from the S21 Ultra can be viewed in our gallery.


The smartphone has an Exynos 2100 chip. It is developed using 5-nm technology, which means for the user an increase in performance and longer battery life. In the GeekBench 5 test, the device scores 1,071 points on a single core and 3370 points in multi-core mode. Of course, the S21 Ultra pulls all toys at maximum graphics settings.

The feud between Qualcomm and Exynos fans will continue this year, with the former claiming that Samsung owners are getting the “wrong processor”, but in reality, this is far from the case. The architecture of the Exynos 2100 is exactly the same: one powerful core, three weaker cores, and four normal cores.


The S21 Ultra received a 5000 mAh battery. This is more than enough for the average user – the device lasts for two days of battery life in call mode, Internet browsing, YouTube videos. In half an hour, you can charge the device by 50%. The reverse charging function is also supported, with which you can charge headphones or other accessory – its power is 4.5 watts.

Power adapter and headphones

Unfortunately, Samsung has decided to ditch the bundled headphones and power adapters, but this decision is understandable. We are sure that by the end of 2021, at least in the first half of 2022, there will not be a single gadget manufacturer that will complete its flagship devices with a power adapter and headphones. These are modern realities.

Interesting features

For the first time in the history of the Galaxy S series, the device supports the S Pen. But unlike the Note series, it is not included with the device – you can buy it either separately or with a case. Most likely, buyers will prefer the second option. Also, Samsung has improved the fingerprint scanner – now its area is 1.7 times larger than its predecessor.

It is impossible not to mention the technology UBW1. With its help, the device acts as a digital key for the car. In addition, the digital key can be shared with users of other devices, regardless of brand and platform.

Also, the device became one of the first smartphones to support the new Wi-Fi standard – Wi-Fi 6E. It offers up to 4x faster connections than Wi-Fi 6. Like its predecessor, the S21 Ultra is IP68-rated and water-resistant.

Final Word

The Galaxy S21 Ultra is a great smartphone that will surely find its buyer. It offers the user the quintessence of modern technology found in Android flagships today. At the time of this writing, the smartphone has practically no competitors – with the exception of its predecessor, which will gradually leave the market.

It looks that it has some worth for gadget lovers, but it totally depends on your liking and budget either you want to buy this smartphone or not. If you have the S20 Ultra in your hands, then you must decide for yourself whether you need the new chips mentioned above. And if the S10 is older, then this is a reason to think about updating. Technologies, like the world, do not stand still and are constantly evolving.
