iOS devices keep disconnecting

Sadly, you do likely have a system problem with your MacBook Air.

Let’s go over what’s happening with the USB connection between different devices. We have passive devices and active devices (ones that need power). We need to look at the two elements of power what the system has and what it can offer. Both your iPhone & iPad require power and will often stress the ports ability to offer enough power. When the system encounters a device pulling to much power it will shutdown the port! This gets into why does it think its not able to support the device’s need. Is the systems power limited or is the device pulling too much?

Let’s check your systems battery to see if its getting to the end of its life. Install this app CoconutBattery

To check the USB port you’ll need a means to measure what happening at the USB port using a power meter USB Power Meter

Using the meter measure the draw between your PC and your Air does the PC pull more power? Post some pics or vid so we can see Bilder zu einer vorhandenen Frage hinzufügen
