# iPhone 18 Pro Performance Boosted by Cold Soda September 27, 2026 at 11:07 AM > A DIY cooling test using a cold beverage shows a 25% improvement in sustained performance for the iPhone 18 Pro's A20 Pro processor. **Matt Birchler** recently tested the Apple **iPhone 18 Pro** and its [A20 Pro]() processor using a cold can of La Croix as a makeshift cooling device. During a 20-run transcription benchmark, the uncooled handset saw performance drop from 447.9 to 320 words per second. The experiment revealed that placing the cold beverage on the device's rear improved sustained performance by 25%. While the liquid-cooled setup started at 429.5 words per second, it maintained a significantly higher average of 400.4 words per second overall. Thermal management remains critical for mobile chips, as seen in the **Redmagic 11 Pro** or accessories like the **Black Shark Magnetic Phone Cooler 6 Pro**. This test follows previous enthusiast efforts, such as attaching SSD cooling solutions to the iPhone 17 Pro Max. #iPhone18Pro #A20Pro #TechBenchmark #ThermalThrottling [#Apple]() ## Related news ## [Apple VP Criticizes iPhone Screen Protectors]() September 20, 2026 at 12:10 PM ## [Mac Mini M6 Geekbench Scores Surface Online]() September 15, 2026 at 10:36 AM ## [Apple Developing Beats-Branded iPhone Controllers]() September 14, 2026 at 07:24 PM ## [TSMC August Revenue Surges 53% on N2 Chip Demand]() September 10, 2026 at 11:24 AM ## [Apple Developing A20 Pro 2nm Chip for iPhone]() September 9, 2026 at 03:24 PM
