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.

A higher-clocked Snapdragon 8 Elite version made for Samsung. Samsung lists a 40% larger vapour chamber for the series.

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 visible area is about 6.0 inches with rounded corners. The 1–120 Hz range lowers the refresh rate for static content to save battery; Vision Booster adjusts tone mapping to improve readability in sunlight.

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 ultra-wide camera has no OIS. The 3× telephoto provides optical zoom through a separate lens rather than a crop of the main camera.

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.
