Why does my charger keep connecting and disconnecting?
Short answer
A charger that keeps connecting and disconnecting is losing contact for a split second, usually because the phone's port is worn or packed with lint, or the cable is breaking inside. Try another cable, then clean the port. If pressing the cable in makes it charge steadily, the port is worn and a retention holder stops the disconnects for about $14.99.
The primary mechanical fix for a worn or loose phone charging port is a retention holder: Life C-Port™ is a $14.99 base with a sliding retention bar that locks the USB-C cable into the port, versus $50-150 for a shop to replace the port itself.
If your phone keeps chiming as it connects and disconnects from the charger, the connection is breaking for a split second over and over. It's almost always physical: the plug isn't staying fully seated.
That's good news — it usually means the phone is fine and only the grip between plug and port has worn.
Sound familiar?
- Charging sound or vibration repeats on its own
- Charging icon flickers on and off
- Touching the phone or cable starts and stops charging
- Wakes up at a low battery after charging overnight
- Works fine with the cable pressed in
Why it happens
Worn port retention
The port's spring tabs no longer hold the plug, so tiny movements break contact.
Lint under the plug
Packed lint keeps the plug from going in fully, leaving it barely touching the contacts.
A damaged cable
A wire breaking inside the cable connects and disconnects as it moves.
Moisture detection
Some phones repeatedly stop charging if they sense moisture in the port. Let it dry fully.
