00:00 Intro 00:47 Gaming Test 17:15 Temperature Check 17:42 Final Results At a room temperature of 26°C, the iPhone 18 Pro Max ran Wuthering Waves at maximum settings for 16 minutes under sustained heavy load, yet its display temperature only increased from 32°C to 40°C, with remarkably uniform heat distribution across the entire screen. In comparison, the vivo X300 Ultra throttled heavily after just 7 minutes, dropping from 60 FPS to around 20 FPS, while reaching 47°C near the CPU and 40°C near the charging port — a 7°C difference. The REDMAGIC 11 Pro reached 47°C and 42°C, a 5°C difference. An outstanding result for the iPhone 18 Pro Max and its vapor chamber cooling system.
