The Galaxy S21+’s display is exactly the same, but it’s bigger. It measures 6.7 inches, everything else is the same, though. Both displays are also flat, unlike the Ultra’s panel. The Galaxy S21 panel provides 421ppi, while the Galaxy S21+ offers 394ppi.

Both smartphones are fueled by the Snapdragon 888 in some markets, while the Exynos 2100 is included in other markets. Both of those are 5nm 64-bit octa-core processors, and both are quite powerful.

The Galaxy S21 and S21+ include 8GB of LPDDR5 RAM and 128GB / 256GB of internal storage. Both phones come with stereo speakers tuned by AKG. Both phones also support 5G connectivity, and are IP68 certified for water and dust resistance.

Below their displays, you’ll find Qualcomm’s second-gen 3D Sonic in-display fingerprint scanner. AN NFC chip is also included here, in case you were wondering.

Their battery capacities are different, of course

A 4,000mAh battery sits inside the Galaxy S21, while a 4,800mAh unit is included in the Galaxy S21+. Both smartphones support fast wired charging (UFS PD 3.0, AFC, and QC2.0 compatible), and also Fast Wireless Charging 2.0.

Their camera setups are completely identical. Both smartphones include a 64-megapixel, and two 12-megapixel cameras on the back. On top of that, a 10-megapixel camera is included on the front.

The Samsung Galaxy S21 Ultra leads the pack

The Galaxy S21 Ultra is positioned as the company’s most powerful smartphone. Some of its specifications are identical to the ones in the Galaxy S21 and S21+, but there are some significant differences. Most of them are visible in the display and camera sections.

The Galaxy S21 Ultra features a 6.8-inch Edge WQHD+ (3200 x 1440) Dynamic AMOLED 2X Infinity-O display. This panel is curved, and it also comes with an adaptive 120Hz refresh rate. HDR10+ content is also supported. We’re looking at 515ppi here.

The SoC situation is the same as in the Galaxy S21 and S21+. It is fueled by both the Snapdragon 888 and Exynos 2100, it only depends on in which market you end up buying the device.
