Apple's iPhone 18 Pro Max ships with a battery-firmware lock that caps capacity below the 20Wh threshold that triggers international shipping restrictions on single-cell batteries. Once a customer activates the phone for the first time, the lock lifts automatically, restoring the battery to its full rated capacity of roughly 21-22Wh depending on the model. A 'Prepare to Ship' setting can reimpose the cap, limiting charging to 80 percent over 14 days, for anyone sending the device in for repair or resale.

Apple has built a 'Prepare to Ship' firmware feature into the iPhone 18 Pro Max that temporarily caps its battery below the 20Wh transport limit enforced in the US, EU and other regions. Once the device is activated by a customer, the cap lifts and the phone's full 5,391mAh capacity becomes available. The same toggle can be re-enabled manually when shipping a device for repair, trade-in or resale.

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.
