Plugged in but nothing happens? A phone that won't charge at all is frustrating — but the cause is often a simple, cheap fix. Here's how to diagnose it.

1. Rule out the cable and charger

Test with a different cable and wall adapter you know work. Cables fail internally all the time, and it's the easiest thing to eliminate first.

2. Clean the charging port

A blocked port is the most common culprit. Lint compacts into a hard plug at the bottom of the port and stops the cable making contact. Power off and gently clear it with a wooden toothpick — many "dead" phones charge perfectly after this.

3. Force restart

Sometimes it's a software freeze. Force-restart the phone and try again.

4. Look for damage

Inspect the port with a light. Bent pins, corrosion (from moisture), or a loose feel when you plug in all point to a worn or damaged charging port.

The fix

If the port is physically worn or damaged, replacing the charging-port flex assembly is a straightforward DIY repair — far cheaper than a new phone or a shop visit. Our charging-port kits include the flex, tools, adhesive and a video guide.

Shop charging-port repair kits for your model, or grab a battery kit if the port checks out but it still won't hold charge.
