GoKawiilApple adds 'Prepare to Ship' setting for iPhone 18 Pro Max's oversized battery
Apple confirmed the iPhone 18 Pro Max packs a single-cell battery exceeding 20 watt-hours, triggering extra international shipping regulations for large batteries. To comply, Apple built firmware that caps the battery below 20 Wh during manufacturing and transit, only unlocking full capacity once a user activates the phone. A new 'Prepare to Ship' toggle in Settings lets owners discharge the battery back below that threshold before repairs, trade-ins, resale, or gifting.
