Wireless Charger Not Working? 8 Fixes for iPhone, Samsung, and Android

Step-by-Step Guide

1. 1

   Fix 1: Check phone placement on the charger

   Wireless charging requires the phone's coil to align with the charger's coil. On flat Qi pads, the phone's coil is typically in the center of the phone — check the manufacturer's diagram for the exact coil location. Some flat pads work only when the phone is centered precisely; slight misalignment causes no charging or very slow charging. MagSafe eliminates this problem: the magnetic ring aligns the iPhone coil automatically when you place the phone near the charger. For non-MagSafe Qi chargers, try moving the phone slightly on the pad — 1cm in any direction — until the charging indicator appears on the phone.

   Fix 2: Check for case interference

   Phone cases that interfere with wireless charging are the most common cause of wireless chargers failing to charge. Metal cases: any metal case completely blocks wireless charging. Remove the case and test. Thick cases (over 3mm): wireless charging may not work or may charge very slowly through very thick cases. Battery cases: most battery cases charge the battery first, then the phone — the phone may appear uncharged while the case battery is filling. Magnetic wallet cases: metal plates used for magnetic car mounts interfere with the electromagnetic field. Remove any metal plates or magnetic accessories before placing on the wireless charger.

   Fix 3: Verify the power adapter provides enough wattage

   Wireless chargers are powered by a USB-C adapter (or USB-A on older designs) and cannot charge faster than the adapter provides. A 15W MagSafe charger connected to a 12W USB-A adapter charges at 12W maximum, not 15W. Check the adapter wattage: it is printed on the adapter body. Apple's included 5W USB-A adapter does not support MagSafe fast charging at all — the phone will charge, but very slowly. Use a 20W USB-C power adapter minimum for MagSafe, and a 30W+ adapter for multi-device charging stations. Using a USB hub or PC USB port as the power source typically provides 5W or less — never sufficient for fast wireless charging.

   Fix 4: Restart the phone

   On both iPhone and Android, the wireless charging subsystem can enter a fault state after software updates, app installations, or low battery events that prevents the charging circuit from activating. A simple restart clears this fault. Turn the phone off fully, wait 30 seconds, power on, then place on the charger. This is particularly effective for iPhones after iOS updates and Samsung Galaxy phones after One UI updates. On iPhone: if a restart does not fix wireless charging but wired charging works, go to Settings, Battery, Battery Health and check whether the battery health is below 80% — reduced capacity can trigger charging management behavior that affects wireless charging.

   Fix 5: Clean the back of the phone and the charging pad

   Dirt, oil, and debris on the back of the phone or the charging pad surface create a gap between the phone and the charger coil that reduces charging efficiency or prevents charging entirely on thicker debris buildup. Clean the back of the phone and the charging pad surface with a microfiber cloth. For sticky residue, use a cotton swab lightly moistened with isopropyl alcohol and allow both surfaces to dry before replacing the phone. Dust inside the phone's wireless charging area (under removable cases) can interfere with particularly sensitive chargers.

   Fix 6: Check phone wireless charging compatibility

   Wireless charging is not universal — confirm your specific phone model supports Qi, MagSafe, or Qi2. iPhone SE (1st generation) and older iPhones: no wireless charging. Android phones below the flagship tier: wireless charging is often not included — check the phone's specifications page. Some budget Android phones have a wireless charging coil absent from the phone entirely despite the case suggesting otherwise. On Android: Settings, Battery (or similar) shows wireless charging as an option when the hardware is present. If wireless charging is not listed in Settings, the phone does not support it regardless of charger quality.

   Fix 7: Try a different USB cable between the adapter and the pad

   Wireless chargers with detachable USB-C cables between the pad and the adapter can fail due to cable quality or a damaged cable. Replace the USB-C cable between the charger pad and the adapter with a known-good cable. USB-C cables have significant quality variation — a 60W rated cable from a reputable brand performs differently from an unbranded cable at the same wattage rating. For MagSafe, use Apple's cable or an MFi-certified USB-C cable. If the charger works with a different cable, the original cable is the fault.

   Fix 8: Update the charger firmware or reset it

   Some wireless chargers (primarily multi-device stations from Belkin, Anker, and ESR) have firmware that can be updated through a companion app or via USB connection to a computer. Firmware bugs can cause the charger to misidentify connected devices, limit charging speed below the rated maximum, or disable specific device slots. Check whether your charger model has a companion app or firmware update process on the manufacturer's support page. For chargers with no firmware update option: unplug the charger from power, wait 30 seconds, replug — this resets the charger's microcontroller and can clear fault states without a full firmware update.
