Samsung Galaxy S III™ - Can't turn on smartphone

If your smartphone does not turn on, try the following.

Inspect the battery contacts

Your battery may not be seated correctly.

Remove the battery.

  1. Using a soft, dry cloth, remove any debris or residue found on the battery contacts.
    NOTE: The battery contacts are metallic pins located within the battery housing. Make sure that these pins are aligned and in direct contact with the metallic contacts on the battery.
  2. Reinsert the battery.
  3. Turn your smartphone on.
  4. Your smartphone is restarted.

Make sure your battery is fully charged

Make sure that you fully recharge your battery on a regular basis prior to use. Failure to do so can cause your battery to drain more rapidly and shorten its life span.

  • Use your AC adapter to charge the battery. If the battery is completely drained, it will need charging for at least ten minutes.
  • Try to turn your smartphone on by pressing the power button for three seconds.
