10 Tech How-To

iPhone Not Charging with MagSafe or Qi2: Fix It

Guide 10-30812 · Updated · Step by step

If your iPhone won’t charge with a MagSafe or Qi2 charger, the problem is usually a simple one: misalignment, a dirty charging coil, a case that’s too thick, or a power adapter that can’t deliver enough wattage. This guide walks you through the most effective fixes in order, from the quickest check to the more involved troubleshooting steps, so you can get your phone charging again without a trip to the Apple Store.

What You’ll Need

  • A soft, dry, lint-free cloth (microfiber works best)
  • A toothpick or plastic spudger (optional, for cleaning the charging port)
  • A different power adapter (ideally 20W or higher, like the one that came with a recent iPhone or iPad)
  • Another Apple or Qi2-certified charger, if you have one
  • Your iPhone’s model name (to check its charging requirements)
  • Access to the Settings app

Step-by-Step

  1. Check the power source first. Plug your MagSafe or Qi2 charger into a wall outlet, not a USB port on a computer or a power strip that might be faulty. Try a different outlet. If the charger has a light, confirm it’s on. Many wireless chargers have a small LED that indicates power; if it’s off, the adapter or cable is the problem, not your iPhone.
  2. Verify the power adapter wattage. MagSafe chargers need at least a 20W USB-C power adapter to deliver full 15W speed. Qi2 chargers also work best with 20W or higher. If you’re using an old 5W or 12W adapter, the phone may not charge at all, or it may charge extremely slowly. Swap in a 20W or higher adapter and try again.
  3. Remove your iPhone case. Even cases advertised as “MagSafe compatible” can interfere with charging if they’re thick, have a metal plate, a pop socket, or a magnetic mount glued on the back. Take the case off completely and try charging bare. If it works, your case is the issue—either get a thinner one or one that’s officially MagSafe-certified.
  4. Clean the back of your iPhone and the charger. Dust, lint, and sticky residue break the connection. Use a dry microfiber cloth to wipe the back of your phone and the flat surface of the charger. If there’s stubborn grime, slightly dampen the cloth with water (not wet) and wipe again. Let both dry completely before charging.
  5. Check the charging coil alignment. MagSafe and Qi2 chargers use magnets to align the coil. If you’re using a non-magnetic Qi2 charger (a plain Qi pad), the coil is in the center of the phone, just below the camera bump. Move the phone around until you find the sweet spot. For MagSafe, the magnet should snap into place; if it doesn’t, there might be something between the phone and the charger.
  6. Restart your iPhone. A software glitch can sometimes stop wireless charging. Press and hold the side button and either volume button until the power off slider appears. Slide to power off, wait 30 seconds, then turn it back on. Try charging again.
  7. Update iOS. Go to Settings > General > Software Update. If an update is available, install it. Apple regularly fixes charging bugs in iOS updates, so this can resolve issues you didn’t even know were related.
  8. Try a different wireless charger. If you have another MagSafe or Qi2 charger, test it. This isolates whether the problem is your phone or the charger. If the second charger works, the first one is faulty—check its cable, or replace it.
  9. Check for overheating. If your iPhone is hot (over 95°F / 35°C), it will pause wireless charging to protect the battery. Move it to a cooler room, take it out of direct sunlight, and wait 15 minutes before trying again. Also, don’t use your phone while it’s on the charger—that generates heat and slows charging.
  10. Clean the Lightning/USB-C port (if you also can’t charge wired). If your phone also fails to charge with a cable, the port might be clogged with lint. Use a toothpick or plastic spudger to gently scoop out any debris. Do not use metal, and do not blow compressed air into the port. After cleaning, try a wired charge to confirm the port works, then return to wireless.
  11. Reset all settings. This doesn’t erase your data, but it resets Wi-Fi, Bluetooth, and other system settings. Go to Settings > General   > Transfer or Reset iPhone > Reset > Reset All Settings. Your phone will restart. You’ll need to re-enter Wi-Fi passwords, but your photos and apps stay. Try charging after the reset.
  12. Check battery health. Go to Settings > Battery > Battery Health & Charging. If it says “Service” or shows a warning, the battery may be degraded. Wireless charging can become unreliable with a failing battery, though this is less common than the issues above.

Common Mistakes

  • Using a charger with a built-in cable that’s frayed or bent. The cable is often the weakest link. Inspect it for damage and try a different cable if possible.
  • Leaving a credit card or RFID chip in your case. These block the magnetic field and prevent charging. Remove them before placing the phone on the charger.
  • Charging with the phone upside down. Some non-MagSafe Qi2 pads require the phone to be face-up with the top of the phone pointing toward the top of the pad. Check the charger’s manual for orientation.
  • Ignoring the “accessory not supported” alert. If your iPhone shows this, the charger is not certified or is defective. Stop using it; it can damage your battery.
  • Placing the phone on the charger while it’s in a thick OtterBox or Lifeproof case. These often exceed the 3mm distance limit for wireless charging. Always test without the case.

Tips

  • Use the Apple 20W or 30W adapter for best results with MagSafe. Third-party adapters that support USB-C Power Delivery (PD) also work.
  • Keep the charger flat. If you’re using a stand-style charger, make sure the phone is seated fully against the charging surface. A slight tilt can break the connection.
  • Enable “Optimized Battery Charging” if you plan to leave the phone on the charger overnight. It’s on by default, but you can check in Settings > Battery > Battery Health.
  • Restart your phone before concluding the hardware is broken. A simple reboot fixes a surprising number of charging issues.
  • Buy chargers that are MagSafe-certified or Qi2-certified. Cheap non-certified chargers often have weak magnets or poor coil alignment, leading to intermittent charging.

Troubleshooting

If the phone charges with a cable but not wirelessly: The wireless coil in the phone may be damaged, or the charger is incompatible. Try a different certified charger. If that fails, the phone’s internal coil might need service—contact Apple Support or an authorized repair center.

If the phone charges but very slowly: Check the adapter wattage (needs 20W+), remove the case, and make sure the phone isn’t hot. Also, if you’re using a Qi2 charger that isn’t MagSafe, it may only deliver 7.5W instead of 15W—that’s normal for non-MagSafe Qi chargers.

If the phone gets hot and stops charging: This is thermal protection. Remove the case, move to a cooler spot, and don’t use the phone while charging. If it still overheats, the charger may be defective—try another one.

If the phone shows a charging icon but the percentage goes down: The charger is delivering less power than the phone is using. Close background apps, lower screen brightness, and turn off features like Always-On Display. If it still drains, the charger is too weak—upgrade to a 20W adapter.

If nothing works after all steps: The issue might be the phone’s software or hardware. Back up your phone, then try a factory reset via Settings > General > Transfer or Reset iPhone > Erase All Content and Settings. If it still won’t charge wirelessly after a clean setup, the wireless charging coil is likely faulty and needs hardware repair.

Frequently Asked Questions

Why does my iPhone charge with a cable but not with MagSafe?

This usually points to a problem with the wireless charging coil, a thick case, or a defective MagSafe charger. Test with a different certified charger and without a case first. If it still fails, the coil may need repair.

Can a phone case prevent MagSafe charging?

Yes. Cases thicker than about 3mm, cases with metal plates, magnets, or pop sockets, and non-MagSafe cases can block or weaken the magnetic connection. Remove the case to test.

Is it safe to leave my iPhone on a MagSafe charger overnight?

Yes. Modern iPhones have optimized battery charging that limits the charge to 80% until just before you wake up, reducing battery wear. It’s safe to leave it on overnight.

Why does my iPhone charge to 80% and stop?

That’s the “Optimized Battery Charging” feature. It’s designed to slow down charging when it predicts you’ll be away from the charger for a long time. You can turn it off in Settings > Battery > Battery Health & Charging, but it’s recommended to leave it on.

Does Qi2 charging work on all iPhones?

No. Qi2 is supported on iPhone 15 and later models. Older iPhones support standard Qi charging (up to 7.5W) but not the faster Qi2 15W speed. Check your phone’s model in Settings > General > About.

Can I use a MagSafe charger with an iPhone that has a cracked back glass?

It might still work, but the crack can interfere with the magnetic alignment and the coil connection. It’s also a safety risk if the crack exposes internal components. Consider repairing the back glass first.
