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.
GoKawiil's interpretation of the reporting above, not reported fact.
This shows how battery size increases now collide with global shipping safety rules, forcing hardware makers to solve logistics problems with software rather than design changes. It also signals Apple is prioritizing significant battery life gains in its flagship line, even if it means adding extra steps for consumers before reselling or shipping devices.
- iPhone 18 Pro Max battery exceeds 20 Wh, triggering added shipping regulations.
