iPhone 18 Pro benchmark boosted by giving it a cold drink
3x the vapor-chamber surface area can only do so much; luckily the fridge helped with sustained performance
A recent experiment by software developer Matt Birchler revealed that placing a cold drink on the back of the iPhone 18 Pro can significantly boost its performance. Birchler conducted a series of benchmark tests on the iPhone 18 Pro, the 17 Pro, and the M4 Pro MacBook Pro using an app called Quick Subtitles. The 18 Pro series features a vapor chamber with three times the surface area of its predecessor, improving thermal management.
Birchler found that the 18 Pro performed 50% better than the 17 Pro, but both devices heated up. The 18 Pro took longer to warm up but warmed up faster once it did. Birchler then placed a cold La Croix can on the back of the 18 Pro during a benchmark test, and the device maintained a "fair" thermal state throughout the 20 runs, achieving a 14% faster performance compared to when the can was not present.
