iPhone 15 Ditches Lightning for USB-C, Bringing Speed Boost But Compatibility Headaches for Many Users
-
USB-C is more flexible and powerful than Lightning, but brings compatibility headaches many iPhone users haven't dealt with before.
-
The iPhone 15 comes with a USB-C cable limited to slow USB 2.0 data speeds, while the Pro has a faster USB 3 cable.
-
There are 3 separate USB standards - the connector, data rates, and power delivery - which cause confusion about cable and device capabilities.
-
Cheaper cables often cut corners, only supporting older, slower USB versions to lower costs. Watch for certification marks and product info.
-
For most users charging will work fine, but power users should buy quality cables, especially for the Pro models that support fast transfer speeds.
