Apple has introduced a new Prepare to Ship option for the iPhone 18 Pro Max after increasing the device’s battery capacity beyond 20 watt-hours (Wh). The feature is designed to help owners send their phones in for repair, trade-in, return, or gifting without running into stricter shipping regulations for high-capacity batteries.
Why the 20Wh Battery Threshold Matters
In most countries and regions, devices with a single-cell battery above 20Wh are subject to additional shipping requirements. To keep the iPhone 18 Pro Max compliant through the supply chain, Apple uses a battery-firmware solution that keeps the battery below 20Wh during manufacturing and transport. Once the device is activated, the software restriction is removed and the battery operates at its full capacity.
How Prepare to Ship Works
When you need to send your iPhone 18 Pro Max to Apple for service, trade-in, return, or as a gift, the Prepare to Ship feature discharges the battery below the 20Wh threshold. It also applies a charging limit so the battery stays within the required range during transit.
To use the feature:
- Open Settings.
- Go to General.
- Tap Transfer or Reset iPhone.
- Select Prepare to Ship.
Apple says the process typically takes only a few minutes, but a fully charged device may take up to a couple of hours to complete. During discharge, the iPhone 18 Pro Max may feel warmer than usual, but it should cool down once the process finishes.
No Safety Concern, Says Apple
Apple has clarified that Prepare to Ship is not a response to a battery safety problem. The iPhone 18 Pro Max battery remains safe for shipping and air travel, and the additional step simply helps owners meet current regulations. Apple’s shipping guidance also recommends discharging the phone to 25% or less before switching it off and packing it in the provided shipping kit.
For anyone planning to send back an iPhone 18 Pro Max, the new feature should help streamline the process and avoid shipping delays.
