Briefings

Apple introduced a 'Prepare to Ship' feature on September 21, 2026, to comply with international shipping regulations for the iPhone 18 Pro Max battery. The battery is designed to exceed 20 Wh capacity, triggering restrictions. To avoid this, the battery-firmware solution limits capacity below 20 Wh from manufacturing until activation. Users can manually trigger this limit via Settings. Apple warns the battery may become warmer than usual during discharge, though it remains safe for air travel. The feature was documented on Apple's support site.

Key points

• The iPhone 18 Pro Max battery uses a firmware solution to limit capacity below 20 Wh from manufacturing until activation to comply with shipping regulations. Users can manually trigger this feature via the 'Prepare to Ship' setting in Settings.
• Apple documented this shipping workaround on its support site, warning that the battery may become warmer than usual during discharge but remains safe for air travel.

Context and limitations
