The Switch

Why Apple Switched to USB-C

Watch Out

The Problem with Cheap USB-C Cables

Warning: cheap cables can damage your iPhone. The switch to USB-C brought a flood of uncertified cables from unknown brands. These cables look the same but can deliver inconsistent power that damages your battery, cause overheating, and break inside the port leaving fragments that block charging. Always use Apple-certified or MFi-approved USB-C cables. If a cable costs $2 on Amazon it is probably not safe for your iPhone.
