Symptoms
- Phone doesn't show a charging indicator when placed on the pad
- Charging is very slow or stops and starts
- Phone gets warm but doesn't gain charge
- Works with case off but not with case on
Likely causes
- CommonPhone case too thick or has metal/magnetsWireless charging needs close contact and can be blocked by thick cases, metal plates, or magnetic mounts/wallets.
- CommonPhone not centered on the charging coilWireless pads have a specific coil location, and even slight misalignment can prevent charging.
- PossiblePhone or pad doesn't support enough wattageSome phones need a certain power level to charge, and the car's pad may supply less.
- PossibleDebris or dust on the charging pad surfaceCoins, dirt, or debris on the pad can interfere with the connection or even cause overheating.
What to do
- Remove the phone case, or try a known thin, non-metal case, and test charging again.
- Reposition the phone slowly on the pad until you see a charging indicator, since coil alignment is often narrow.
- Clear any coins, cards, or debris off the charging pad surface before placing the phone.
- Check your phone and car's charging pad specifications to confirm they're compatible in wattage.
- Try a different phone on the same pad to see if the issue is phone-specific.
- If the phone gets warm without charging, stop use temporarily, since this can indicate a poor connection generating heat.
When to call a pro
If a compatible phone with no case still won't charge on a clean pad, a dealer can test the wireless charging module.
