Comparison of Galaxy S21, Galaxy S21 Plus and Galaxy S21 Ultra


Samsung on Thursday unveiled three new phones in the flagship Galaxy S Series: galaxy S21, Galaxy S21 Plus, and Galaxy S21 Ultra, as well as the announcement of wireless headphones (Galaxy Buds Pro) and a device to track lost objects called galaxyTag Smart.

The three phones share many features, most notably: a powerful processor, large-sized screens with a high refresh rate of up to 120 Hz – making the animation look smoother – and large-capacity batteries, a built-in ultrasonic fingerprint sensor, and 5G connectivity support.

The larger Galaxy S21 Ultra in the series is the first Galaxy S-Series phone to support the S-Pen and the Wifi 6E.

All phones are powered by Qualcomm's 8-core Snapdragon 888 processor at a 2.84 GHz frequency, a 5 nm factory, or Samsung's 8-core Exynos 2100 processor with a 2.9GHz frequency, a 5-nanometer factory, both processors offering excellent performance, better energy efficiency, improved artificial intelligence features, improved connectivity, and significant camera improvements.

But it's clear that Samsung is following a new trend this year with its flagship phone chain, announcing Galaxy S21 phones earlier than each year, and offering them at lower prices as well, for example, the smaller S21 starts at $799, and the S21 Plus starts at $999, which is about $200 lower than the Galaxy S20 series phones released last year to meet the needs of different users.
