Samsung quotes 40% NPU, 37% CPU and 30% GPU gains over the previous generation. This version is tuned for Galaxy with higher clocks than the standard Snapdragon 8 Elite.

Samsung introduced this version as a Snapdragon optimised for Galaxy and exclusive to the S23 series at launch.

The vapor chamber spreads heat from the chip into the body, helping clocks hold longer in extended gaming.

The viewable area is smaller than the diagonal because of rounded corners and the camera hole. Refresh that drops to 1 Hz saves power on static content; Vision Booster adjusts tone mapping in bright light.

The refresh rate varies between 48 and 120 Hz depending on content; the lower rate on static screens saves battery. Vision Booster adjusts contrast and colour to keep the screen readable in bright light. The size is measured as a full rectangle; the viewable area is smaller because of the rounded corners and camera hole.

Used on the front only. Corning says it survived drops of up to 2.2 m onto a concrete-like surface in internal lab tests; this is not a durability guarantee for any given phone.

Titanium is used only on the frame, excluding the volume and side keys.

Per Samsung, 3× and 5× are optical; 2× and 10× are “optical quality” zoom made by sensor cropping. OIS is optical image stabilisation.

The telephoto gives 3x optical zoom; zoom beyond that is digital. According to Samsung the wide camera records 8K video at 30 fps.

Log records a flat profile for colour grading; results depend on the editing workflow. Audio Eraser can reduce layers such as voices, music, wind and crowd separately in videos.

The 45 W adapter is sold separately. Samsung quotes up to 31 hours of video playback. Wireless PowerShare charges earbuds or a watch from the back of the phone.

According to Android Central’s one-year report, the phone received One UI 8 (Android 16) ahead of schedule.

5G/LTE availability depends on market and carrier.

Wi‑Fi 6E needs a router that supports 6 GHz; band availability varies by market and operator.

Water resistance is not permanent and may diminish over time.

Colour availability varies by country and carrier.

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

The typical value is the average of battery samples measured by a third-party lab under IEC 61960; the rated value is the minimum capacity.

45 W needs a 5 A cable; the adapter is sold separately. Wired charging is compatible with QC2.0 and AFC, wireless with WPC. PowerShare needs more than 30% battery to charge another device. The S23 is limited to 25 W.

Samsung promised four Android upgrades and five years of security updates for the S23 series; timing varies by model and market.

Samsung does not advise beach or pool use.
