Symptoms

  • Charging feels intermittent
  • Speaker sound is slightly muffled
  • Buttons feel less responsive than before
  • Visible dust or lint in openings

Likely causes

  • CommonNormal accumulation from pockets, bags, and daily useFabric lint and environmental dust naturally collect in every opening over months of use.

What to do

  1. Power off the phone before cleaning any openings.
  2. Use a flashlight to inspect the charging port, speaker grilles, and microphone holes for visible buildup.
  3. Clean each opening with short bursts of compressed air held at a slight angle.
  4. Use a wooden toothpick or soft dry brush for stubborn debris in the charging port — never metal.
  5. Wipe down buttons and seams with a dry microfiber cloth.
  6. Make this a monthly habit if you don't use a case, or every few months if you do.

Tools and parts

  • Compressed air
  • Wooden toothpick
  • Soft brush
  • Microfiber cloth

When to call a pro

If regular cleaning doesn't keep up with buildup or you notice a burning smell or unusual heat, have a professional inspect and clean the internals.
