10 Tech How-To

How to Charge an iPhone Wirelessly with MagSafe or Qi

Guide 10-42386 · Updated · Step by step

This guide walks you through charging your iPhone wirelessly using either Apple’s MagSafe system or the standard Qi wireless charging protocol. You’ll learn what equipment you need, how to position your phone correctly, and how to fix common issues when charging doesn’t work as expected.

What You’ll Need

  • An iPhone that supports wireless charging (iPhone 8 or later, including all SE models from 2020 onward).
  • A MagSafe charger (for iPhone 12 or later) or any Qi-certified wireless charging pad.
  • A USB power adapter (Apple recommends 20W or higher for MagSafe fast charging; most Qi pads work with a 5W or 10W adapter).
  • A USB-C or USB-A cable compatible with your charger (usually included).
  • A clear, flat surface to place the charger on.

Step-by-Step

  1. Plug in your charger. Connect the wireless charger to a power source using the included cable and a compatible wall adapter. Ensure the adapter is plugged into a working outlet.
  2. Check your iPhone model. If you have an iPhone 12 or newer (including the iPhone SE 3rd generation), you can use MagSafe. For older models (iPhone 8 through iPhone 11), you’ll need a standard Qi charger.
  3. Remove any thick case. Cases thicker than about 3mm or those with metal, magnets (other than MagSafe), or battery packs can block the charging signal. Remove the case if you’re unsure.
  4. Place the phone on the charger. For MagSafe, align the magnetic ring on the back of your phone with the charger—it will snap into place. For Qi, position the center of the phone’s back (roughly the middle of the Apple logo) over the charging coil indicator on the pad.
  5. Wait for the charging indicator. A chime will sound (if your phone isn’t on silent) and a battery icon with a lightning bolt will appear in the status bar. On iPhone 12 and later, the lock screen may briefly show a green charging circle.
  6. Adjust if needed. If the phone doesn’t start charging within a few seconds, lift it and reposition it. For Qi pads, try moving the phone slightly up, down, left, or right until the charging indicator appears.
  7. Leave it to charge. Once connected, leave the phone on the charger until it reaches your desired battery level. Avoid using the phone heavily while it’s charging, as this can slow charging or cause overheating.

Common Mistakes

  • Using a case with metal or magnets. Metal interferes with the magnetic field, and non-MagSafe magnets can misalign the coils. Even thin metal plates for car mounts will block charging.
  • Placing the phone upside down or off-center. The charging coil is in the upper-middle area of the phone’s back. If the phone is too low or too high, it won’t charge.
  • Using a low-wattage adapter. Many Qi pads require at least 5W, but some older adapters provide only 5W and may not deliver enough power to charge while the phone is in use. For MagSafe, a 20W adapter is recommended for full speed.
  • Ignoring overheating. If your phone gets hot, charging may stop or slow down. Remove thick cases and avoid charging in direct sunlight or on soft surfaces like beds or sofas that trap heat.
  • Assuming all Qi chargers are the same. Some cheap chargers may not be certified and could charge very slowly or not at all. Look for the Qi logo on the packaging.

Tips

  • Use MagSafe for faster charging. MagSafe delivers up to 15W on iPhone 12 and later, while standard Qi chargers are limited to 7.5W on iPhones.
  • Keep the charger clean. Dust and lint on the charging surface or the back of your phone can reduce charging efficiency. Wipe both with a dry microfiber cloth occasionally.
  • Turn on Airplane Mode for a quicker top-up. Disabling cellular and Wi-Fi reduces power draw, so your phone charges faster.
  • Use a stand-style charger. If you use your phone as a clock or want to see notifications while charging, a stand that props the phone up can be more convenient than a flat pad.
  • Check for firmware updates. Occasionally, Apple releases iOS updates that improve wireless charging compatibility. Keep your iPhone updated to avoid issues.

Troubleshooting

  • Phone doesn’t charge at all. First, unplug the charger and plug it back in. Then, try a different wall outlet and a different USB cable. If it still fails, test the charger with another phone (if possible) to isolate the problem.
  • Charging is very slow. Make sure you’re using a compatible adapter (20W for MagSafe, at least 5W for Qi). Also, close battery-draining apps and avoid using the phone while it’s on the charger.
  • Charging stops after a few minutes. This often indicates overheating. Remove the phone from the charger, let it cool down, and try again without a case. If it still stops, the charger may be defective.
  • The phone doesn’t snap onto MagSafe. If your phone doesn’t attach magnetically, you may have a non-MagSafe case or the charger might be a Qi-only model. Remove the case and try again. If it still doesn’t snap, you likely have a Qi charger.
  • Charging works but the phone gets very hot. This can happen with thick cases or if the phone is placed on a surface that doesn’t dissipate heat. Remove the case and place the charger on a hard, flat surface.
  • Charging icon appears but battery percentage goes down. If you’re using the phone heavily (like playing games) while charging, the power draw may exceed the wireless charging rate. Pause heavy use or switch to a wired charger for faster power delivery.

Frequently Asked Questions

Can I use any Qi charger with my iPhone?

Yes, any Qi-certified charger will work with iPhone 8 and later. However, charging speed is limited to 7.5W on iPhones, even if the charger supports higher output.

Does MagSafe work with older iPhones?

MagSafe chargers are compatible with iPhone 8 and later, but older models (iPhone 11 and earlier) won’t have the magnetic alignment and will charge at standard Qi speed (7.5W).

Can I charge my iPhone wirelessly with a case on?

Yes, but the case must be thin (less than about 3mm) and free of metal or magnets. Apple’s own MagSafe cases work fine, as do most silicone and plastic cases.

Is wireless charging slower than wired charging?

Generally, yes. MagSafe maxes out at 15W, while a wired charger can deliver 20W or more on newer iPhones. Qi charging is even slower at 7.5W. For a quick boost, wired is faster.

Can I use my phone while it’s wirelessly charging?

Yes, but it may slow charging and increase heat. If you need to use the phone, consider a stand-style charger so it’s propped up and you can still see the screen.

Do I need to buy Apple’s official MagSafe charger?

No, there are many third-party MagSafe-compatible chargers that work well. Just ensure they are Apple-certified (MFi) or at least have good reviews. Non-certified ones may charge slower or not align properly.
