When to Replace the Charging Flex
You likely need to swap out this component if your device exhibits any of these symptoms:
- No power delivery: The phone fails to respond or charge entirely when plugged into a USB Type-C cable.
- Intermittent charging: Power cuts in and out, requiring you to wiggle or position the cable at a specific angle.
- Slow charging: The device charges at a fraction of its normal speed and no longer triggers its VOOC 3.0 fast charging.
- Secondary component failure: The charging board also houses or connects to the primary microphone and audio jack. If callers cannot hear you or headphones are not recognized, a damaged flex is often the culprit.
