Symptoms
- Charging alert or moisture warning appears on screen
- Phone won't charge even though the cable and adapter work fine elsewhere
- Issue started right after water exposure
Likely causes
- CommonBuilt-in moisture detection disabling charging as a safety featureThis is intentional and protects against corrosion or shorting while the port is wet.
- CommonActual water still present in the portTrapped moisture will keep triggering the warning until it evaporates.
- PossibleCorrosion already forming on port contactsMore likely if the phone was wet for a long time before drying.
What to do
- Do not force a charge or dry with heat (hair dryer, microwave, oven) — this can cause more damage.
- Shake the phone gently, port facing down, to remove visible water.
- Leave the phone in a dry, room-temperature spot for several hours to overnight.
- Try charging again after it's had time to dry; the moisture warning should clear once the port is dry.
- If the warning persists after 24 hours of drying, there may be trapped water or early corrosion that needs professional attention.
When to call a pro
If the moisture warning won't clear after a full day of drying, a repair shop can inspect and clean the port to remove any remaining moisture or early corrosion.
