iPhone 18 Pro Max Battery Restrictions Affect Shipping and Repairs

The new iPhone 18 Pro Max introduces an unusual regulatory requirement related to its battery, which exceeds 20 watt-hours for the first time in an Apple device. This threshold subjects the battery to stricter shipping regulations for lithium-ion batteries on flights and commercial deliveries.

To comply, Apple implements a factory-level restriction on the battery's capacity. Upon initial setup, the limitation is removed, allowing full battery usage. However, when the device needs to be shipped, such as for repairs or trade-ins, users must activate a new 'Prepare to Ship' setting. This feature initiates a controlled discharge of the battery to meet shipping standards and prevents full recharging.

This process can cause noticeable device heating. Furthermore, disabling the 'Prepare to Ship' function might take up to 14 days, depending on the circumstances, before full charging capacity is restored. Apple emphasizes that this restriction does not indicate a safety issue for normal device use, including during flights when carried by passengers.

The iPhone 18 Pro and the foldable iPhone Duo are not affected by these battery shipping rules, as their batteries do not exceed the 20 watt-hour limit in a single cell. The iPhone 18 Pro Max also features market-specific modems, with U.S. models using Qualcomm's Snapdragon X80 and other regions, including Israel, using Apple's independent C2 modem. Additionally, the camera bump on the iPhone 18 Pro Max is 0.1 millimeters thicker than previous models, requiring new cases despite physical compatibility with iPhone 17 series covers.
