Samsung S21 vs Samsung S21 Ultra Comparison

Samsung S21 vs S21 Ultra

Coming from the same series as each other, these two smartphones have some differences to note. The main difference is their size and weight, which affects both grip and screen size. There are also differences in performance. Read below to understand which model is the right smartphone for you.

Samsung S21, the most compact

The Samsung S21 is also the most compact of the two. It weighs just 127 grams compared to 228 grams for S21 Ultra, and measures 71.2 × 151.7 × 7.9 mm, while the Samsung S21 Ultra has a dimension of 75.6 × 161.5 × 7.8 mm. The screen size is therefore smaller than that of the S21 Ultra. It is 6.2 inches against 6.8 inches for the Ultra model. Regarding camerta capability, the S21 has three 12 Mpx rear cameras with a 12 Mpx Ultra wide-angle and a 64 Mpx telephoto lens. The S21 Ultra stands out from the crowd with 108 Mpx, a wide-angle lens and two telephoto lenses, as a result it is able to take better high-quality photos.

Samsung S21 Ultra, the most powerful

The XL size of the screen is great for anyone who watches content on their smartphone. It is accompanied by a high definition display, which is superior to that of the Samsung S21, and overall allows better image quality and refresh rate. The difference between the two models is also in the storage capacity. The S21 is available in 128 and 256 GB versions, but the S21 Ultra offers storage options of 128, 256 and 512 GB instead. The S21 Ultra is also the only smartphone to be equipped with the S-Pen.

With the same bionic chips as each other, these two smartphones are similar in terms of performance. However, the S21 Ultra is more convincing when it comes to handling background applications and photography. It also has a larger screen which makes it suitable for the more demanding user who uses their smartphone more intensively. The S21 is still an excellent smartphone: capable of photographic prowess with an admirable grip. Both have 3 years of internal software updates - the choice is yours in regards to deciding which smartphone will suit your needs better.
