iPhone Wireless Charging Not Working? Here Is How to Fix It
An iPhone that refuses to charge on a wireless charging pad, charges intermittently, or stops charging after a few seconds is usually dealing with a case or alignment issue, not a hardware failure. When iPhone wireless charging not working becomes an issue, the cause is usually something you can fix yourself. Wireless charging uses electromagnetic induction between a coil in the charger and a coil inside the iPhone, and anything that disrupts the alignment or the magnetic field between those coils will prevent or interrupt charging.

Why Wireless Charging Fails on iPhone — IPhone Wireless Charging Not Working
The iPhone case is too thick or contains metal. Wireless charging requires close proximity between the phone's charging coil and the charger's coil. Cases thicker than 3mm, cases with metal plates (common with magnetic car mounts), metal rings, credit card holders, or cases with built-in kickstands that include metal components all block or weaken the electromagnetic field. The charging pad may chime as if charging has started, but the connection drops within seconds.
The iPhone is not centered on the pad. The charging coil inside the iPhone sits in a specific location on the back of the phone. If the iPhone is placed off-center on the charging pad, the coils do not align and charging either fails entirely or operates at reduced efficiency. This is especially common with single-coil chargers that have a small sweet spot.
The charging pad does not support the correct wattage. iPhones support 7.5W wireless charging with Qi-certified chargers and up to 15W with MagSafe chargers. A charger that outputs only 5W will charge the iPhone, but very slowly. Some cheaper wireless chargers are not Qi-certified and may not work with iPhones at all despite working with other phones.
A software glitch is preventing the charging circuit from engaging. After certain iOS updates or if the iPhone's battery management system detects an unusual condition, the phone may refuse to accept wireless charge input. A restart usually clears this state.
The iPhone or charger surface is dirty. Dust, debris, or a film of oil on either the back of the iPhone or the surface of the charging pad can create enough of a gap to weaken the electromagnetic coupling. Even a thin layer of grime that you cannot feel with your fingers can reduce charging efficiency enough to trigger the charger to stop.
Remove the iPhone Case
Take the case off completely and place the bare iPhone on the wireless charging pad. If charging starts immediately and holds steady, the case is the problem.
Metal components are the most common culprit. Check your case for any of these:
- A metal plate glued inside the case for a magnetic car mount
- A built-in card holder with a metal clip or magnetic closure
- A metal kickstand or ring holder attached to the back
- A battery case with its own charging circuitry that interferes with the pad
If you want to keep your case, switch to a MagSafe-compatible case (for iPhone 12 and later) that is specifically designed to pass the wireless charging signal through. MagSafe cases include a ring of magnets that align the phone perfectly on the charger, solving both the metal and alignment problems simultaneously.

Center the iPhone on the Charging Pad
The iPhone's wireless charging coil is located in the center-back of the phone. Place the iPhone face up on the charging pad, then slowly slide it until you see the charging indicator appear on screen (the green battery icon or the charging chime).
If you are using a flat pad, the sweet spot is usually marked by a logo or a subtle indent in the center. Stand-style chargers are more forgiving because the phone rests in a fixed position, but make sure the phone is flush against the stand and not tilted by a thick case edge.
For iPhone 12 and later, a MagSafe charger eliminates alignment guesswork. The magnets snap the charger to the exact right position every time. This is the most reliable fix for intermittent "charging starts then stops" behavior caused by the phone shifting slightly on a flat pad.
Clean Both Surfaces
Wireless charging is sensitive to the gap between the charger and the phone. Even a thin layer of dust or oil can reduce efficiency enough to stop charging.
- Wipe the back of the iPhone with a dry, lint-free microfiber cloth. Pay attention to the center area where the charging coil sits.
- Clean the surface of the charging pad with the same cloth. If the pad has a rubber or silicone surface, make sure no debris is embedded in it.
- Check for any stickers, screen protectors applied to the back of the phone, or adhesive residue from old accessories. Remove anything that adds thickness between the phone and the pad.
After cleaning, place the iPhone on the pad and confirm that charging starts and holds for at least 30 seconds without dropping.
Restart Your iPhone
A restart clears the battery management state and re-initializes the wireless charging controller.
Press and hold the Side button and either Volume button until the "slide to power off" slider appears. Slide to turn off. Wait 10 seconds, then press and hold the Side button until the Apple logo appears.
After the restart, place the iPhone on the wireless charger immediately. If the phone was refusing to charge due to a software glitch in the battery management system, the restart resolves it. This is especially effective if wireless charging stopped working after an iOS update or after the phone overheated during a previous charging session.

Check the Charger and Power Source
The wireless charger itself may be the problem. Test with a different charger if you have one available, or test your current charger with a different phone.
Verify the power adapter. Most wireless chargers require a USB-C or USB-A power adapter that outputs at least 10W to deliver the full 7.5W to an iPhone. Using a low-power adapter (like the old 5W iPhone cube) will either not charge at all or charge extremely slowly. Check the charger's documentation for the recommended adapter wattage.
Check the cable. A damaged or low-quality USB cable between the power adapter and the charging pad can limit power delivery. Try a different cable, preferably the one that came with the charger.
Try a different outlet. A power strip with a tripped surge protector, a loose wall outlet, or an outlet on a circuit that is overloaded can deliver inconsistent power to the charger.
If the charger works with another phone but not your iPhone, the problem is on the iPhone's side. If the charger does not work with any phone, the charger is faulty.
Check for Overheating
Wireless charging generates heat. If the iPhone's internal temperature gets too high, iOS automatically stops wireless charging to protect the battery. You will see a temperature warning on screen, or the phone will simply stop charging without an alert.
Common causes of overheating during wireless charging:
- Charging in direct sunlight or near a heat source
- Using the phone intensively (gaming, video streaming, navigation) while it charges wirelessly
- A thick case trapping heat between the phone and the charger
- Stacking the phone on top of another device on the charging pad
If the phone is hot to the touch, remove it from the charger, take off the case, and let it cool for 10 to 15 minutes before trying again. Charge in a cooler environment and avoid heavy use during wireless charging if overheating is recurring.
Update iOS
Apple addresses wireless charging bugs in iOS updates. Several past releases have included fixes for issues where wireless charging stopped mid-session or failed to start with specific charger models.
Go to Settings > General > Software Update. Install any available update and test wireless charging afterward.
Reset All Settings
If wireless charging still does not work after all the steps above, a settings reset clears any configuration that might be interfering without deleting your data.
Go to Settings > General > Transfer or Reset iPhone > Reset > Reset All Settings. This resets Wi-Fi passwords, Bluetooth pairings, and all other settings to defaults. Your photos, apps, and data remain. After the restart, test wireless charging again.
If the phone still will not charge wirelessly after a settings reset but charges fine with a Lightning or USB-C cable, the wireless charging coil inside the phone may be damaged. Contact Apple Support or visit an Apple Store for hardware diagnosis.

Frequently Asked Questions About iPhone Wireless Charging Issues
Which iPhones support wireless charging?
All iPhones from the iPhone 8 onward support Qi wireless charging at 7.5W. iPhone 12 and later also support MagSafe charging at up to 15W. Older iPhones (iPhone 7 and earlier) do not have wireless charging hardware and cannot be charged wirelessly, even with a case that claims to add the feature.
Can I use any wireless charger with an iPhone?
Any Qi-certified wireless charger works with iPhones that support wireless charging. For the fastest speeds, use a MagSafe charger (iPhone 12 and later) or a Qi charger rated for at least 7.5W with a compatible power adapter. Non-certified chargers may not work or may charge very slowly.
Why does my iPhone charge wirelessly but very slowly?
Slow wireless charging is usually caused by a low-power adapter, a thick case reducing coil alignment, or the phone throttling charge speed due to heat. Make sure you are using an adapter that outputs at least 10W, remove the case, and charge in a cool environment. Also check that Low Power Mode is off, as it can affect charging behavior on some iOS versions.
Does wireless charging damage the iPhone battery?
Wireless charging generates slightly more heat than wired charging, which can affect long-term battery health if the phone is consistently charged wirelessly in hot environments. However, iOS includes battery management features (Optimized Battery Charging) that learn your routine and delay charging past 80% until you need the phone. This minimizes wear. For most users, wireless charging does not noticeably degrade battery health compared to wired charging.
Can I charge my iPhone through a PopSocket or wallet case?
Most PopSockets and wallet cases are too thick or contain metal components that block wireless charging. MagSafe-compatible PopSockets and wallet attachments are designed to be removed before charging or are thin enough to allow charging through them. Check the product specifications for wireless charging compatibility before purchasing.
