We thought the Samsung Galaxy S21 Ultra was the best smartphone on the market when it first came out in early 2021. But OnePlus is the company that truly understands how to give the titans of the smartphone industry a bloody nose. The OnePlus 9 Pro also adds a few of its own clever tricks to the mix. Okmobile and PhoneBolee are the trending websites that provide full information and specifications of these two mobile models, along with prices.
So let’s compare the performance of two of the largest phones of 2021 in a head-to-head match. We’ll go into great detail about these two models and compare them side by side so you can decide which is better for you given your needs. The similarities and significant differences between the Samsung Galaxy S21 and the OnePlus 9 Pro will be examined in this article.
Display and Size
The screen on the OnePlus 9 Pro is a sizable 6.7 inches. As a result, you can view apps, movies, and games in high resolution, but controlling the device with one hand is challenging. It also implies that not every pocket can accommodate a smartphone. You can see every last detail of your favorite shows and games on the incredibly sharp Quad HD screen.
There are 120 refreshes of the screen per second. The locations of the stereo speakers, SIM card tray, and USB-C port are remarkably similar. On the OnePlus 9 Pro, the volume rocker is, however, found on the left side. Similar glass and aluminum construction is provided, and the display’s and the back panel’s edges are lightly rounded.
On the other hand, the Samsung Galaxy S21 has a 6.2-inch screen and is significantly smaller than the OnePlus 9 Pro. One of the few high-end smartphones that is simple to operate with one hand is the S21. You can watch high-quality movies and television shows, but the details are less clear. Additionally, this screen refreshes 120 times every second.
The Samsung Galaxy S21 Ultra is bulkier, has a larger camera bump, and all color options have a matte finish. The newest Gorilla Glass Victus protects the phone’s body and display, and it has an IP68 rating for water and dust resistance. The enormous size of the phone doesn’t feel overpowering, and the overall weight feels premium in the hand.
There is only one 8-megapixel telephoto lens on the OnePlus 9 Plus, and it can zoom in up to 3.3 times. This comes with a 2-megapixel monochrome lens to improve your black-and-white pictures. The OnePlus 9 Pro seems to have the advantage when it comes to videography. Compared to the Galaxy S21 Ultra, it can handle 8K video at 30 frames per second, and it also crops in less because of an unusual 16:11 aspect ratio.
The Galaxy S21 Ultra’s detail is comparable to that of the 9 Pro, but the software processing oversoftens the Galaxy S21 Ultra’s images, giving the impression that they are more detailed image.
The Galaxy S21 Ultra utilizes a 1/2.55″ 12-megapixel ultrawide camera. Samsung uses two 10 MP telephoto sensors to aim for the moon. One of them provides a 3x optical zoom, which is fairly common. The S21 Ultra still creates photos that are brighter and more saturated.
Although this will come down to personal preference, I did prefer the S21 Ultra’s color science over the 9 Pro’s overall appearance. The Galaxy S21 Ultra could be the right camera phone for you if you prefer images that are brighter and punchier.
Operating System and Performance
OnePlus gives the Android 11 operating system a unique twist, similar to almost every other company at the moment. As a result, OxygenOS is the operating system for the OnePlus 9 Pro. Not much of the original Android 11 was altered by OnePlus. Software updates are promised by OnePlus through Android 13 in 2023. Up until March 2024, security updates will be sent to you.
I might also point out that Oxygen OS is a little bit simpler to use when navigating, but again, this is just my opinion. Both default launchers have native Google integration with the Google Discover feed on the left-most homescreen, making it simple to find settings.
Samsung OneUI operates on the S21. In comparison to many other brands, this version of Android 11 looks different. Your personal assistant, Bixby, is accessible on the S21.You can use voice commands to operate your smartphone thanks to this. You will be able to download software updates for the S21 through at least Android 14 in 2024.
Due to the fact that both devices come equipped with the most recent Snapdragon 888 processor, the Galaxy S21 Ultra and OnePlus 9 Pro are almost identical. While the S21 Ultra starts with a base of 12GB and goes all the way up to a whopping 16GB for the top model, the 9 Pro offers options of 8GB and 12GB of RAM. The Galaxy S21 Ultra scored 5,022 on Geekbench 4’s single-core test and 13,915 on the multi-core test in our tests.
The larger battery capacity of Samsung’s phone (5000 mAh) as opposed to the OnePlus device’s 4500 mAh probably explains why it weighs more. In fact, the OnePlus 9 Pro ships with a charger, but it’s a monster 65W brick that provides a quick charge in a matter of minutes.
With 25W of wired charging available for the Samsung Galaxy S21 Ultra, you can reach about half that amount in the same amount of time. It’s interesting to see how competing ideas contrast with one another. OnePlus seems content with offering a shorter battery life in exchange for faster charging, whereas Samsung went with a longer raw battery life.
We have listed the main features of the OnePlus 9 Pro and the Samsung Galaxy S21 Ultra. According to our opinion, the Galaxy S21 Ultra is the obvious choice to make if you prefer a more premium design, a longer battery life, and extremely quick charging times. If you want a smoother UI and faster charging times, however, choose the OnePlus 9 Pro.
