The four holes on the left of the charging port of the Apple 13 Pro Max are used to connect accessories. The four holes are part of Apple's \"MagSafe\" technology for wireless charging, connecting magnetic accessories and transmitting data.
MagSafe allows chargers and accessories to be magnetically attached to the phone, providing a convenient wireless charging experience, and also supports the connection of magnetic shell, card case, bracket and other accessories, increasing the flexibility of use.
This design makes the charging and accessory connection more stable, avoids the inconvenience and loss of cable insertion and removal, and improves the user experience.
