The phone doesn’t care about the brick. It only cares about one end of the cable. All your old USB-A <-> lightning cables still work with their USB-A bricks.

- totalZero 6y agoIt is my understanding that what you describe is not how charging works nowadays. For example, the new 15W MagSafe charger doesn't work at 15W if you plug it into any old brick. A particular charging profile (voltage and current) must be negotiated between and supported by both the charger and the device.
