Apple could ditch the Lightning connector on the highest-end versions of the iPhone in 2021, meaning the devices will require wireless charging, according to a report on Thursday from Ming-Chi Kuo, an analyst at TF Securities.

The removal of the Lightning cable, along with other differentiating updates, will boost shipment and the average selling price (ASP) of the top iPhone models, Kuo wrote. Without the connector, the top tier iPhone would provide a "completely wireless experience," Kuo said.

Speculation has been building for several years that Apple plans to remove the Lightning cable. As far back as 2017, Kuo predicted that Apple would discard the Lightning connector in favor of the USB Type-C connector, which is widely used across the industry.

However, Apple has continued to include Lightning ports in the latest iPhone models. Apple's new iPhone 11, iPhone 11 Pro and iPhone 11 Pro Max models, which were announced in September, all have Lightning ports.

Apple has started to include the USB-C connector in some products. The new iPhones support Apple's fast-charger, which promises to deliver up to a 50% charge in 30 minutes. The charger uses USB-C and requires iPhone users to buy a specific cable that goes from the Lightning connector to USB-C ports.
