Try Different Cables:

Cables fail frequently, especially cheap ones. Try a different cable before assuming phone issues. Inspect cables for damage at connection points.

Test Multiple Chargers:

The charging brick could be faulty. Test with known-working chargers. Use certified chargers matching your phone's specifications.

Clean the Charging Port:

Pocket lint and dust accumulate in ports. Gently clean with a toothpick or soft brush. Avoid metal objects that could damage contacts.

Check for Debris Blocking Connection:

Inspect the port with a flashlight. Compressed air helps remove stubborn debris. Proper connection is essential for charging.

Restart Your Phone:

Software glitches can stop charging. Restart the phone and try again. This simple step often resolves unexpected issues.

Check Battery Health:

Old batteries lose capacity. iPhone: Settings > Battery > Battery Health. Very old batteries may need replacement.

Conclusion:

Cables and dirty ports cause most charging issues. If all else fails, professional inspection can identify hardware problems.
