   iPhone 18 Pro Max ships with battery locked below legal limit

   Apple delivers the iPhone 18 Pro Max with a firmware state called Prepare to Ship that restricts the single-cell battery capacity to under 20 watt-hours. This temporary software cap allows new devices to bypass standard transport and shipping regulations governing larger lithium-ion power sources. The device automatically removes this limit during initial user activation, releasing the full battery capacity for everyday use. Owners who need to mail their devices later for trade-ins, repairs, returns, or gifts can manually reapply the restriction through the settings menu.

   Why it matters

   Single-cell batteries exceeding 20 watt-hours face strict transport rules and additional shipping requirements across many regions. Apple developed this software-based workaround to avoid those distribution hurdles while still increasing overall battery life for users. Devices arriving with lower-than-advertised power levels are operating as intended rather than exhibiting a hardware defect.

   What is confirmed

   • The iPhone 18 Pro Max carries a single-cell battery rated above 20 watt-hours.
   • A factory firmware state called Prepare to Ship keeps the battery under 20 watt-hours while the phone is built and shipped.
   • The full battery capacity unlocks the first time the handset is activated.
   • Users can manually engage the Prepare to Ship feature in Settings to discharge the battery below 20 watt-hours and set a charge limit for future shipping.

   What to watch next

   • Broader international logistics rulings on software-capped battery transport compliance
   • User feedback regarding the manual use of the Prepare to Ship setting for repairs and returns

   Apple uses firmware cap to ship iPhone 18 Pro Max battery

   Apple is shipping the iPhone 18 Pro Max with a firmware cap that limits the battery to below 20Wh to comply with safety regulations during transport. This allows the device to bypass standard shipping restrictions for larger batteries. Once a user activates the phone for the first time, the system automatically unlocks the full 21.75Wh battery capacity. This method ensures the hardware reaches customers without violating shipping laws while still providing the advertised power once in use.

   Why it matters

   Shipping regulations often limit the capacity of lithium batteries allowed on aircraft and cargo vessels. By electronically restricting the charge, Apple avoids these logistical barriers. This approach may influence how other manufacturers handle high-capacity batteries in the US and EU markets.

   What is confirmed

   • The iPhone 18 Pro Max uses a firmware cap to stay below 20Wh during shipping for safety regulations.
   • The device automatically unlocks its full 21.75Wh battery capacity upon first activation.
   • Apple implemented this process to circumvent battery shipping restrictions for the iPhone 18 Pro Max.

   Still unconfirmed

   • Apple's shipping method could lead to more Android phones in the US and EU featuring larger batteries.

   What to watch next

   • Confirmation from aviation or shipping regulators regarding the legality of firmware-capped batteries
   • Official Apple documentation detailing the activation process for battery unlocking
