Industry Hardware Pricing Context: According to reports from 9to5Mac and authorized Apple repair schedules, iPhone 18 Pro series batteries reflect higher out-of-warranty replacement pricing than previous generations ($119 for iPhone 18 Pro and $139 for iPhone 18 Pro Max in the US). The increase stems from redesigned stainless steel battery casing for EU battery-removability compliance, high-pressure adhesive dissipation systems, and strict waterproofing requalification.
