You are currently viewing SAMSUNG Galaxy S21 vs S21 Ultra Comparison

In this article, I give you my Samsung Galaxy S21 vs S21 Ultra comparison with specs included. The new phones for 2021 in the flagship line from Samsung and released a bit earlier than usual. Usually, they come out a couple of months later in the year but they’ve pushed it up obviously.

The exciting news to kick off our discussion is the significant price drop from the previous generation of Samsung phones, with the latest models starting at $200 less. This alone is a promising start, right? And when we delve into the comparison between the S20 Ultra and the S21 Ultra, the improvements are truly remarkable, especially in terms of camera capabilities. Moreover, there are other exciting additions like the inclusion of the S Pen.

This initial review aims to provide a sneak peek into the new phones, focusing on the most notable features. However, a detailed analysis of all the features will be available once the phones hit the market. This is partly due to embargoes and also to allow for sufficient time to thoroughly test the devices. Additionally, a comprehensive review of the new Samsung Buds Pro will be coming up shortly, as well as an evaluation of their new Smart Tags, which are Bluetooth-enabled trackers designed to prevent you from losing your belongings.

Now, turning our attention back to the phones themselves, Samsung graciously provided us with review units of two out of the three models: the S21, featuring a 6.2-inch display, and the S21 Ultra, boasting a massive 6.8-inch display. Nestled in between these sizes is the S21 Plus, which used to be a favorite for those seeking a balance between screen real estate and portability, all at a lower price point compared to the Ultra.

With the Ultra models now offering improved features and a reduced price, the decision between the base and plus models becomes more nuanced. The base S21 model starts at $799, the S21 Plus at $999, and the Ultra at $1,199. Notably, all models now sport matte finishes, and the Ultra comes in more subdued color options compared to the smaller models.

Under the hood, the devices are powered by the Snapdragon 888 chipset, the latest in 5G technology. While benchmarks will be shared in the full review, it’s safe to assume that these devices will deliver impressive performance, as is the norm with each new iteration.

For those outside the United States, the Exynos 2100 CPU will be the chipset of choice. While we didn’t receive review units with this chipset, Samsung’s Exynos variants typically offer comparable performance to their Snapdragon counterparts.

In terms of camera hardware, the base S21 and S21 Plus models feature similar setups to their predecessors but with enhancements in computational photography. This translates to more natural-looking images with improved color accuracy. However, the real star of the show is the S21 Ultra, which represents a significant leap forward in smartphone photography. With its revamped camera system, including a 108-megapixel main sensor, dual telephoto lenses, and improved zoom capabilities, the Ultra is poised to deliver unparalleled imaging performance.

Another noteworthy addition to the Ultra is S Pen support, signaling a potential shift in Samsung’s product lineup. While the absence of Bluetooth features found in the Note series may disappoint some, the inclusion of the S Pen opens up new possibilities for productivity and creativity on the S21 Ultra’s expansive display.

Design-wise, the decision to opt for flat screens on the S21 and S21 Plus models is a welcome change. While curved screens may have been trendy in the past, flat screens offer a more practical and secure grip, reducing accidental touches along the edges.

Other features like the ultrasonic fingerprint scanner, Gorilla Glass Victus, and variable refresh rate displays further enhance the overall user experience. Additionally, improvements in battery capacity and charging speeds ensure that these devices can keep up with your busy lifestyle.

However, it’s not all sunshine and rainbows. The omission of a charger and MicroSD card slot may disappoint some users accustomed to these features. Nevertheless, with support for all major carriers and 5G bands, as well as the inclusion of power-sharing capabilities, the S21 series remains a compelling choice for consumers.

In conclusion, the Samsung Galaxy S21 series represents a significant step forward in smartphone technology, offering a compelling blend of performance, features, and value. Whether you opt for the base model, the Plus, or the Ultra, you can expect a premium experience that pushes the boundaries of what’s possible with a smartphone.
