iPhone Air Power Button Flex Cable

The iPhone Air is remarkably thin, and that design leaves very little room around the side button. If the button has stopped responding or works only sometimes, the thin flex cable behind it may be damaged, often after a drop on that edge.

This aftermarket power button flex cable is made for the iPhone Air and replaces the switch and cable behind the side button. The listing doesn't say whether other buttons share this flex.

Common reasons it fails

Impacts on the edge, liquid that reaches the switch, wear from daily use and damage during another repair are the usual causes. You might find the button needs a hard press, ignores a double-click for Apple Pay, or doesn't wake the phone at all. A case pressing on the button or a dented frame can mimic the same fault, so test without the case first.

Take extra care opening the Air and lifting the old flex, since thin phones leave little margin for error. AssistiveTouch works as an on-screen button in the meantime.

For most owners, a repair shop with iPhone Air experience is the safest route. Once fitted, the button should respond to a normal press again.
