CoolingVapor chamber 40% larger than before; new thermal interface material (TIM)

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

Display6.9-inch QHD+ Dynamic AMOLED 2X; 1–120 Hz adaptive refresh; Vision Booster

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.

Samsung		—
Front coverCorning Gorilla Armor 2 anti-reflective glass ceramic

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.
