Apple is preparing to swap the proprietary Lightning port on its iPhones next year for the nearly universally-embraced USB-C, claims company analyst Ming-Chi Kuo.

In a pair of tweets, Kuo said Apple was going to make the change in 2023, basing this claim on an unspecified “survey” (presumably of component manufacturers, from whom Kuo seems to get a lot of his information for predictions about future Apple products).

Kuo said that adopting USB-C “could improve iPhone’s transfer and charging speed in hardware designs, but the final spec details still depend on iOS support.”

Kuo’s prediction is hardly without precedence — rumors and speculation about Apple adopting USB-C for the iPhone have swirled for years. The smartphone industry at large has embraced the reversible USB-C standard, and Apple itself has got partly on board, adding USB-C to its most recent iPads and using USB-C-compatible Thunderbolt ports on many Macs. Pressure to switch has built from policymakers, too, with the EU still considering a proposal that would make USB-C ports mandatory on smartphones and other electronics (with the intention of reducing e-waste by standardizing chargers and data cables).
