Apple Adds iPhone 18 Pro Max Shipping Mode for Batteries Over 20Wh

Summary
Apple published a support document detailing a new “Prepare to Ship” option for iPhone 18 Pro Max, letting users ready the phone for returns, repairs, trade-ins, resale or gifting.
The feature exists because the model’s single-cell battery exceeds 20 watt-hours, a threshold that triggers extra shipping rules in most countries and regions.
Prepare to Ship discharges the battery below 20Wh and applies a charge cap; the process can take a few minutes or up to a couple of hours from a full charge.
Apple said the phone may run warmer while discharging, remains usable during the process unless erased, and shows a red “Ready to Ship” badge when complete.
The same compliance logic applies from the factory: firmware keeps capacity below 20Wh in transit, then unlocks full battery capacity when the user activates the device.
