As a tech enthusiast, I’ve always been fascinated by the innovative features of each new phone release. The Samsung Galaxy S21 is no exception, flaunting a sleek design and an array of impressive specs. However, the buzz surrounding Samsung’s new Galaxy S23 has me wondering if it’s worth the wait. In this article, I’ll compare the Samsung Galaxy S23 vs S21 to help you decide which option is better.

The Samsung Galaxy S21 offers top-of-the-line specifications and features, from a stunning 6.2-inch Dynamic AMOLED 2X display with a refresh rate 120Hz to a powerful Exynos 2100 processor that ensures seamless navigation and multitasking. In addition, the camera system on the Samsung Galaxy S21 is equally impressive, with a triple-lens setup that includes a 64MP primary sensor and a 12MP ultra-wide lens, offering the perfect balance of versatility and quality.

However, rumors surrounding the Samsung Galaxy S23 have tech enthusiasts eagerly anticipating its release. Despite a lack of official information, it’s speculated that Samsung’s next flagship phone will come with upgrades across the board, including a more powerful processor, a 200-megapixel camera, and an improved display. While these remain rumors, they’re enough to leave many wondering if it’s worth holding out for the Galaxy S23, especially with the release expected sometime next year.

Design And Build Quality Comparison

Regarding design and build quality, the Samsung Galaxy S23 and S21 have a lot in common, but a few key differences distinguish the two phones.

Firstly, both phones have a sleek and modern design with a metal frame and glass back. In addition, the S23 features a slightly larger screen than the S21, at 6.7 inches compared to 6.2 inches, and both phones have a similar resolution of 2400 x 1080 pixels. The S23 also boasts a higher refresh rate of 120Hz, compared to the S21’s 60Hz, which makes for smoother scrolling and better gaming performance.

Another notable difference is the placement of the front-facing camera. On the S21, it is located within a punch-hole cutout in the center of the screen. At the same time, on the S23, it is contained within an under-display camera, which allows for an even more seamless and immersive viewing experience.

Regarding build quality, both phones are made with Corning Gorilla Glass Victus and are rated IP68 for water and dust resistance. However, the S23 has an upgraded aluminum frame, which provides improved durability and a premium feel.

Overall, while both phones’ design and build quality are impressive, the Samsung Galaxy S23 edges out the S21 slightly with its larger screen, higher refresh rate, under-display camera, and upgraded aluminum frame.

Samsung Galaxy S23 vs S21

One of the key differences between Samsung Galaxy S23 and S21 is the screen and display. The S23 features a larger 6.9-inch Dynamic AMOLED X2 display with a resolution of 3200 x 1440 pixels, while the S21 has a 6.2-inch Dynamic AMOLED display of 2400 x 1080 pixels. This means the S23 has a higher pixel density than the S21, resulting in sharper and more vivid visuals.

Moreover, the S23 has a variable refresh rate of up to 120Hz, which can automatically adjust the refresh rate depending on the content being displayed on the screen. On the other hand, the S21 has a fixed refresh rate of 120Hz, which can drain the battery faster. However, the S21 has a peak brightness of 1,500 nits, which is higher than the S23’s peak brightness of 1,300 nits.

In terms of color accuracy, both phones have similar results, with the S23 having a slight edge due to its higher pixel density. Additionally, the S23 comes with a new under-display camera technology, which eliminates the need for a notch or punch-hole on the screen, resulting in a seamless and unobstructed display. The S21, however, has a punch-hole camera cutout in the center of the display.
