Samsung Galaxy S21 Ultra Review

Design/Display
The Galaxy S21 Ultra carries forward the design philosophy from its predecessors but elevates it to a whole new level. It’s a substantial device, exuding a sense of luxury and sturdiness. Weighing just 227 grams, it feels substantial in the hand, thanks in part to the larger battery and premium materials.
The front and back are protected by Gorilla Glass Victus, surrounded by a stainless steel frame that adds to its durability.
However, the standout feature is the camera module on the back, which is quite pronounced. This design choice may cause the phone to wobble when placed on a flat surface, but a protective case can mitigate this issue.
The display of the Galaxy S21 Ultra is a true masterpiece. It boasts a massive 6.8-inch Dynamic AMOLED 2X panel with a stunning resolution of 1440×3200 pixels and supports HDR10+.
The device also features an adaptive 120Hz refresh rate, which enhances smoothness. This adaptive refresh rate dynamically adjusts between 10Hz and 120Hz based on content, saving battery life.

Camera
The camera system of the Samsung Galaxy S21 Ultra is nothing short of extraordinary. It features a sophisticated array of lenses, including a 108MP wide-angle lens, a 12MP periscope telephoto lens, and a 12MP ultra-wide lens.
The 108MP sensor, in particular, captures incredible detail, while the periscope lens offers astonishing zoom capabilities with up to 100X Space Zoom which is 2X that of Note 20 Ultra.

Whether you’re shooting in broad daylight, low light, or even at night, the Galaxy S21 Ultra delivers exceptional image quality. This extends to video recording, where it excels in both 4K and 8K resolutions.
The selfie camera is equally impressive, featuring a 40MP lens that captures sharp and vibrant self-portraits. This is the rear camera of some mid-range phones!

Battery
The Galaxy S21 Ultra’s battery life is praiseworthy. With a 5,000mAh battery, it easily lasts a full day of heavy usage. Even with the dynamic 120Hz display, the device manages power efficiently. A great upgrade to Note 20 Ultra which has 4,500mAh.
If you are worried if the phone will really last you for a full day, Samsung said the Galaxy S21 Ultra can last up to 18hrs on internet use, 22hrs if you’re just playing videos, 81hrs if you’re playing audio, and 41hrs talk time.
This again, is impressive but consider the fact that the more generated by the phone, the faster the battery would drain.
For the charging, I wouldn’t say it’s great just like the camera but the phone supports (USB Type C) 25W fast charging, capable of replenishing the battery quickly. Additionally, it offers 15W wireless charging and 4.5W reverse wireless charging. Samsung’s attention to battery performance and charging options is commendable.
And of course, the battery is not removable.

Software/Performance
Running on OneUI 3.1 based on Android 11, the Galaxy Samsung S21 Ultra provides a rich and intuitive user experience. The combination of Samsung’s software optimization and the powerful Exynos 2100 (International) or Snapdragon 888 (USA) SoC ensures top-tier performance. You can seamlessly multitask, play demanding games, and handle any task with ease.
The good news is that the phone will be receiving 4 major updates which means the Galaxy S21 Ultra will be getting Android 15! The UI will also be updated. You have a whole lot of features to enjoy on the phone such as the S-pen and Wireless DEX to mention a few.
For performance, you have nothing to worry about.

Storage/Memory
The Galaxy S21 Ultra comes with 256GB or 512GB of which 220GB is available, paired with a generous 12GB or 16G RAM. This configuration ensures speedy performance and provides plenty of space for your apps, media, and files.
Unfortunately, you cannot expand the Samsung Galaxy S21 Ultra’s memory with an SD card or any external story, you have to use your remaining 220G judiciously.
If we are being honest, I think the built-in storage should be enough for you.
