About the Samsung Galaxy S23 Ultra SM-S918B
Samsung SM-S918BZKHEUE is listed in the smartphones category. The recorded specifications include display diagonal: 17.3 cm (6.8"); internal storage capacity: 512 GB; mobile network generation: 5G; operating system installed: Android 13. This entry covers manufacturer code SM-S918BZKHEUE. Specifications relate to this exact source record; other editions or packages may differ.
The 17.3 cm (6.8") display is specified at 3088 x 1440 pixels. Consider these together: a larger screen provides more physical space, while resolution determines the number of pixels available. Neither specification establishes brightness, colour accuracy or motion quality.
The listed maximum refresh rate is 120 Hz. A higher refresh rate can make scrolling and supported games look smoother. The rate used depends on the app and display settings, and can affect battery life.

What does the COR Score mean?
One consistent scale makes different publishers’ ratings easier to compare. The original review still tells you why a critic reached that verdict.
Read our scoring methodology →Scale conversion · example
8/ 104.00/ 5
An illustration of conversion, not this product’s rating.
Check the match
Identify the exact model and the version reviewed. Check the manufacturer code, configuration and supplied accessories.
Compare on one scale
Convert usable ratings to five points, count each publisher once and give each critic equal weight.
