Memory depends on the storage option; usable space is lower because of preloaded software. There is no memory card slot.

Adapter separate; actual speed depends on charging conditions.

Samsung does not recommend beach or pool use.

Adaptive refresh drops to as low as 1 Hz when content is static to save power and rises to 120 Hz when scrolling and gaming. Vision Booster adjusts colour and contrast in bright conditions across three lighting levels; the edge curve is reduced compared with the S22 Ultra.

According to Samsung, the S23 series was the first S series to use Gorilla Glass Victus 2.

The 200 MP sensor outputs 200, 50 or 12 MP images through pixel binning. 100x Space Zoom combines 10x optical with 10x AI-assisted digital zoom; image quality may deteriorate beyond 10x. The optical stabilisation angle was doubled compared with the S22 Ultra.

The Expert RAW app (downloaded separately from the Galaxy Store) offers RAW capture at up to 50 MP.

On the S23 series the front camera gets fast autofocus and 60 fps Super HDR.

45 W requires a separately sold 45 W adapter and a 5 A USB-C cable; wired charging is compatible with QC2.0 and AFC. Wireless PowerShare charges Qi-compatible devices from the back of the phone when the battery is above 30%.
