Wireless Charger Stopped Working? Fix It Fast

Quick answer

Start with the cheapest fix: remove the phone case and place the phone directly on the pad. If it charges, the case was blocking the coil. If not, test a different USB-C cable and wall adapter, then check for heat or debris. Most wireless charging failures are caused by alignment, a thick case, or a weak power source, not a dead charger.

Check the case and alignment first

A phone case is the most common reason a wireless charger stops working. Cases thicker than 3 mm, those with metal plates, magnets, or card slots, can block the charging coil. Remove the case and place the phone directly on the pad. If charging starts, you need a thinner MagSafe-compatible case or a charger that tolerates more distance. Alignment matters too: the phone's coil must sit over the charger's coil. MagSafe and Qi2 chargers use magnets to snap into place, but non-magnetic pads require you to center the phone manually. Shift the phone slightly until the charging indicator lights up.

Test the cable, adapter, and power source

A wireless charger is only as good as the power feeding it. Swap the USB-C cable for a known-good one, then try a different wall adapter. Many chargers need at least 20W to deliver full speed; a weak 5W adapter may not trigger charging at all. If your charger has a status light, check whether it blinks or stays dark. No light usually means no power reaching the pad. Also inspect the port on the charger for lint or bent pins. If you use a power strip, plug the adapter directly into a wall outlet to rule out a faulty strip.

Clean the pad and cool the phone

Dust, lint, and sticky residue on the charging surface can prevent the phone from making full contact. Unplug the charger and wipe the pad with a dry, soft cloth. Avoid liquids. Heat is another culprit: wireless charging generates heat, and phones throttle or stop charging when they get too warm. Remove the case, move the phone off direct sunlight, and let it cool for a few minutes. If your phone feels hot, stop charging and try again once it reaches room temperature. A charger that works fine when cool but quits after 10 minutes is usually a heat or alignment issue, not a dead unit.

When to stop troubleshooting and replace

If you have tried a different cable, adapter, removed the case, cleaned the pad, and the phone still does not charge, the charger itself may have failed. Test your phone on another wireless charger to confirm the phone's coil works. If the phone charges elsewhere, the original charger is the problem. At that point, replacing it is more practical than repairing. Look for a charger that matches your phone's Qi2 or MagSafe standard and provides enough power for your needs. For example, the PowerBug 25W (Qi2.2) snaps MagSafe and Qi2.2 phones into place and includes a USB-C port for a second device, which helps reduce clutter and eliminates the guesswork of alignment.

Diagnosis: symptom, cause, and next step

• Phone does not charge at all, no light on charger: No power is reaching the pad. Check the USB-C cable, wall adapter, and outlet. Try a different cable and a 20W-or-higher adapter. If the light stays off with a known-good cable and adapter, the charger is likely dead.
• Charging starts and stops repeatedly: Usually alignment or a case issue. Remove the case, center the phone, and make sure no metal objects are between phone and pad. If it charges reliably without the case, buy a thinner MagSafe-compatible case.
• Phone gets hot and charging slows or stops: Heat buildup. Remove the case, unplug and let everything cool, and avoid charging in direct sun or under a pillow. If overheating continues with a cool phone and no case, the charger may be faulty.
• Charger works with one phone but not another: The failing phone may have a case problem, a damaged coil, or software that needs a restart. Try the phone on a different wireless charger. If the phone fails on multiple chargers, the phone needs service, not a new charger.

Product facts

• PowerBug 25W (Qi2.2): PowerBug 25W (Qi2.2) is a minimal wireless charger that keeps your iPhone visible and in use, with a built-in USB-C port to power a second device. If your old charger failed and you want a tidy setup that also charges a second device, this replaces two cables with one.
• Valet 4.25 in.: Valet 4.25 in. offers Qi2.2 wireless charging up to 25W and a premium leather surface that holds your phone and essentials. A dedicated spot with strong magnets reduces misalignment, one of the top reasons wireless charging stops working.
