Apple Adds iPhone 18 Pro Max Shipping Limit for Batteries Above 20Wh

Summary
Apple introduced a new Prepare to Ship setting for the iPhone 18 Pro Max that reduces usable battery capacity below 20Wh before repair, trade-in or other shipments.
The feature is required because the model’s single-cell battery exceeds 20 watt-hours, triggering extra shipping rules that do not apply to other iPhones.
Firmware already keeps unactivated or boxed phones under the 20Wh threshold, and full capacity is restored once a customer activates the device.
Settings can discharge the phone and impose a temporary charge cap until it shows Ready to Ship; Apple says the handset may run warmer during the process.
Apple says the iPhone 18 Pro Max remains safe for shipping and air travel, with the limit added solely to comply with transport requirements.
