Wireless Charger Not Charging Your Phone? Common Fixes

Quick Answer

Most wireless charging failures come down to three things: the phone is not centered on the coil, the case is too thick or has metal in it, or the pad is not getting enough power from its adapter. Fix alignment first, then remove the case, then check the power source. If the pad still will not charge after those steps, the charger itself is the likely problem.

Check Alignment Before Anything Else

Wireless charging coils are small, and the phone's coil has to sit almost directly over the pad's coil. A shift of even half an inch can drop the connection or make it cut in and out. If your phone charges for a few seconds then stops, alignment is the first suspect.

Place the phone flat and centered on the pad, then watch for the charging icon. If it flickers, slide the phone slowly until the icon stays steady. On pads without a visible guide, use the phone's camera bump or the pad's edge as a reference point and keep it consistent each night.

• Remove thick grips or pop-sockets before placing the phone down.
• Center the phone over the pad's marked zone or logo.
• If the icon flickers, nudge the phone until it holds steady.

Test the Case and Any Attachments

Cases are the second most common cause. Anything thicker than about 3 mm, or any case with a metal plate, magnet, or card holder built in, can block the charging field. Even a thin case can interfere if it has a metallic ring for a magnetic mount.

Take the case off and set the phone directly on the pad. If it charges without the case, you have your answer. A slim case under 3 mm often works fine, but a wallet case or a case with a metal plate usually will not.

• Remove the case and test the phone bare on the pad.
• Check for hidden metal plates or magnetic rings inside the case.
• If a slim case works but a thick one does not, switch cases rather than the charger.

Verify the Power Source and Cable

A wireless pad needs enough wattage from its wall adapter. If you are using an old 5W phone charger or a USB port on a laptop, the pad may not have enough power to start charging, especially if the phone is also running a game or navigation.

Use the adapter that came with the pad, or a known-good adapter that meets the pad's input requirement. Swap the cable too, since a worn USB cable can deliver power inconsistently. Plug the pad directly into a wall outlet, not a power strip that is already loaded with other devices.

• Use the original adapter or one with equal or higher output.
• Try a different cable and a different wall outlet.
• Avoid daisy-chaining through unpowered hubs or weak USB ports.

Watch for Heat and Interference

Wireless charging generates heat, and both phones and pads throttle or pause charging when they get too warm. If your phone feels hot after a failed charge, let it cool and try again in a cooler spot. Charging under a pillow or on a bed can trap heat and trigger a stop.

Other devices can also interfere. Keep the pad away from metal objects, credit cards, and other electronics. If the pad sits on a metal desk or near a metal lamp base, move it to a non-metal surface and test again.

• Let a hot phone cool before retrying.
• Charge on a hard, ventilated surface, not fabric.
• Move the pad away from metal objects and other electronics.

Diagnosis: Symptom, Cause, Fix, and Stop Point

• Charges for a few seconds, then stops: The phone coil is drifting off the pad coil, or the case is interfering. Reposition the phone until the icon stays solid, then remove the case and retest. If it holds steady without the case, the case is the problem. If it still cuts out, move to the next check.
• Phone gets warm but does not charge: Heat buildup or a misaligned coil is wasting power as heat instead of charging. Cool the phone, clear anything covering it, and place it centered on a hard surface. If it still only warms up without charging, the pad or adapter is likely underpowered.
• No charging icon at all: The pad may not be receiving power. Confirm the adapter meets the pad's input, swap the cable, and plug directly into a wall outlet. If a known-good adapter and cable still produce nothing, the pad has failed and should be replaced.
• Charges slowly or only sometimes: A weak adapter, a thick case, or a pad that is not rated for your phone's fast-charge standard can all cause this. Test with the case off and the original adapter. If slow charging persists with a proper adapter and no case, the pad's wattage is the limit. Consider a higher-wattage pad.

Products That Address These Issues

• Timex Alarm Clock with Wireless Charger for iPhone, Samsung, and AirPods - Black (TW14B): The Timex TW14 Alarm Clock with Wireless Charging has a 15W wireless charging pad and a high/low dimmer, and operates on a USB-A to USB-C power cable.
