The Samsung Galaxy S21 Ultra phone is one of the flagships of this company with a beautiful design and a glass body that uses the Exynos 2100 chipset. This chipset has a 5nm processor that provides fast and efficient performance and also supports 5G connectivity. The phone has a 6.8-inch Dynamic AMOLED 2X display that has high resolution, high brightness, and an adaptive refresh rate. This display can automatically adjust its refresh rate between 10 and 120 Hz, although it also depends on the content being displayed and the battery level of the phone. This feature ensures that the display is always smooth and relevant to the content being played, while also saving energy. It should be noted that the Galaxy S21 Ultra was the first smartphone to support 120Hz refresh rate and QHD+ resolution at the same time.
Samsung Galaxy S21 Ultra has a unique and powerful camera system that includes four cameras on the back and one camera on the front. The main camera on the back of the phone is a 108-megapixel sensor with Nonacell technology, which can absorb a lot of light and record high-quality photos with a higher dynamic range.
Perhaps the most notable part of the camera system on the back of the phone are the two telephoto cameras, each of which has a resolution of 10 megapixels. These two cameras can zoom up to 100 times on the desired subject. The first telephoto camera has a 3x optical zoom, while the second camera has a 10x optical zoom. This camera system also uses a laser AF sensor to improve the speed and accuracy of autofocus, especially in low light conditions. This phone also has the ability to record videos with 8K quality.
The battery of this veteran Samsung flagship also has a capacity of 5000 mAh with a charging speed of 25 watts. You should know that the Galaxy S21 Ultra in Iran experienced very good sales among flagship phones compared to iPhones.
