OnePlus has finally launched its latest flagship – the OnePlus 9 Pro. Yes, this one is a tad more expensive compared to the OnePlus 9 – the bread and butter phone from the company – but this one is a major step up too. And a quick look at the specification sheet makes it abundantly clear that this phone is going against the best in the Android ecosystem – with the Galaxy S21 Ultra being at the top of that list. On the surface, the OnePlus 9 Pro actually offers more in terms of sheer hardware compared to the Samsung flagship – and for a lot less.

OnePlus 9 Pro vs Galaxy S21 Ultra: Design
Well, this is going to be a tricky one. Both the phones go for curved display aesthetics and employ a glass-and-metal sandwich design. However, the design of the camera bump is something that is going to be up for debate. Notably, both the phones come with an IP68-certified build, which means they can handle a few dunks in a bucket of water. The color options, and surface finish though, will up to your personal preference.
The OnePlus 9 Pro is available in a trio of colors – Morning Mist with a glossy mirror finish, Pine Green with a dual-layer matte texture, and Stellar Black rocking a frosted matte glass texture. As for the Galaxy S21 Ultra, you get to choose between Phantom Black (matte finish) and Phantom Silver. However, if you’re making the purchase from Samsung’s official website, you will get three more options to choose from – Phantom Navy, Phantom Titanium, and Phantom Brown.

Now, let’s talk substance. Both the phones feature a curved AMOLED display with 120Hz refresh rate, HDR10+ certification, and hole-punch (left-cornered on the OnePlus 9 Pro vs centered on the Galaxy S21 Ultra) aesthetics. The screen resolution you get on the OnePlus flagship is 3216 x 1440 pixels, which translates to a pixel density of 525 PPI. The Galaxy S21 Ultra’s screen has a resolution of 3200 x 1440 pixels, offering a slightly lower pixels density of 515 PPI.
Both the phones employ the LTPO technology for adaptive refresh rate, but there’s a slight difference. The panel on OnePlus can intelligently vary the refresh rate value between 1Hz and 120Hz, while the Samsung offering has the lowest refresh rate value set at 5Hz and goes up to 120Hz.
Both the phones draw power from the Qualcomm Snapdragon 888 SoC, however, the Samsung offering also comes in a variant powered by the in-house Exynos 2100 SoC. 5G support is on the table in both cases though. Samsung Galaxy S21 lets you take the configuration choice up to 16GB of RAM and 512GB of onboard storage. OnePlus 9 Pro, on the other hand, goes up to 12GB of LPDDR5 RAM and 256GB of UFS 3.1 storage.
To keep the lights on, OnePlus 9 Pro comes equipped with a 4,500mAh battery that supports an impressive 65W fast charging, taking the battery from 0-100 percent in just 29 minutes. There is also support for insanely fast 50W wireless charging that can fully fill the tank in 43 minutes.
Samsung Galaxy S21 Ultra, on the other hand, comes equipped with a larger 5,000mAh battery, but the peak wired charging wattage is capped at 45W, and the wireless charging speed is much slower yoo. On the bright side, you get support for reverse wireless charging as well.
Another key weapon in the Galaxy S21 Ultra’s arsenal is support for S Pen, which takes the productivity aspect to the next level. But do keep in mind that you have to spend extra cash for the stylus.View Galaxy S21 Ultra 5G S Pen at Samsung
Now, this is where Samsung builds upon a legacy of solid camera performance, while the OnePlus offering emerges as a true challenger with massively upgraded camera hardware and some tuning with help from Hasselblad. The quad-camera setup of the OnePlus 9 Pro includes a custom 48MP Sony IMX789 sensor with OIS that can capture 4K videos at 120FPS, and click 12-bit HDR photos too.
It sits alongside a massive 50MP ultra-wide-angle camera with the Sony IMX766 sensor at its heart. It also pulls the double duty as a macro camera, with a maximum proximity range of 4cm for sharp focus. You will also find an 8MP telephoto camera that can go up to 3.3x optical zoom and 30x digital zoom. And finally, there is also a 2MP monochrome camera as well. Over at the front, you’ll find a 16MP camera housed in a hole-punch to take care of selfies and video calls.
On the Galaxy S21 Ultra, you get a massive 108MP optically stabilized primary camera that can capture 8K videos, sitting alongside a 12MP ultra-wide angle snapper. Unlike the OnePlus 9 Pro which has a single telephoto camera, the Samsung device had two 10MP shooters, one of which relies on a periscope system to deliver a higher lossless zoom range. The first telephoto camera goes up to 3x optical zoom, while the one with the folded lens system delivers 10x optical zoom and up to 100x Super Resolution zoom.
