Cold La Croix Can Boosts iPhone 18 Pro Sustained Performance 25%
A tester placed a chilled La Croix can on an iPhone 18 Pro during A20 Pro benchmarks, gaining 25% sustained performance. The phone had to face down.
Cooling a phone with a cold drink can is not a standard benchmark practice, but it produced measurable gains for one tester. Matt Birchler ran sustained performance tests on an iPhone 18 Pro and placed a chilled can of La Croix on its back, according to tomshardware.com.
The result was a 25% improvement in sustained performance while benchmarking the A20 Pro processor inside the phone.
In its normal configuration, the iPhone 18 Pro hit a maximum of 447.9 words per second before settling to a little over 320 for runs 7 through 20. With the La Croix can, the first run reached 429.5 words per second and the average came in at 400.4 words per second.
The setup had a practical catch: keeping the phone facing down was required during heavy loads.
Purpose-built options exist for this kind of thermal management. The Redmagic 11 Pro is a gaming handset with liquid cooling, and accessories such as the Black Shark Magnetic Phone Cooler 6 Pro, SmallRig Universal Hyper Chill Cooling Phone Cage, and Tilta Khronos Advanced Kit are designed to cool phones. Enthusiasts have also strapped an SSD cooling solution to an iPhone 17 Pro Max.
