How to wirelessly charge your iPhone

Learn how to wirelessly charge your iPhone with Qi-certified charging accessories.

What you need

Your iPhone features integrated wireless charging that allows for an easy and intuitive charging experience. Your iPhone works with Qi-certified chargers that are available as accessories and in cars, cafes, hotels, airports, and furniture. Qi is an open, universal charging standard created by the Wireless Power Consortium (WPC).

Many Qi-certified chargers charge iPhone with the latest version of iOS at rates up to 7.5 watts. These chargers are available at the Apple Online Store and Apple Stores.

Other Qi-certified chargers might vary in functionality and performance. If you have questions, contact the manufacturer.

Charge wirelessly

1. Connect your charger to power. Use the power adapter that came with your accessory or a power adapter recommended by the manufacturer.
2. Place the charger on a level surface or other location recommended by the manufacturer.
3. Place your iPhone on the charger with the display facing up. For best performance, place it in the center of the charger or in the location recommended by manufacturer.
4. Your iPhone should start charging a few seconds after you place it on your wireless charger.

• Learn about charging with the MagSafe Charger and MagSafe Duo Charger.
• Wireless charging uses magnetic induction to charge your iPhone. Don’t place anything between your iPhone and the charger. Magnetic mounts, magnetic cases, or other objects between your iPhone and the charger might reduce performance or damage magnetic strips or RFID chips like those found in some credit cards, security badges, passports, and key fobs. If your case holds any of these sensitive items, remove them before charging or make sure that they aren’t between the back of your iPhone and the charger.
• If your iPhone isn’t charging or is charging slowly and your iPhone has a thick case, metal case, or battery case, try removing the case.
• If your iPhone vibrates—when it gets a notification, for example—your iPhone might shift position. This can cause the charging mat to stop providing power to your iPhone. If this happens often, consider turning off vibration, turning on Do Not Disturb, or using a case to prevent movement.
• Depending on the charging mat you have, you might hear faint noises while your iPhone charges.
• Your iPhone might get slightly warmer while it charges. To extend the lifespan of your battery, if the battery gets too warm, software might limit charging above 80 percent. Your iPhone will charge again when the temperature drops. Try moving your iPhone and charger to a cooler location.
• Your iPhone won’t charge wirelessly when connected to USB. If your iPhone is connected to your computer with USB, or if it’s connected to a USB power adapter, your iPhone will charge using the USB connection.

No Charger in the Box? Everything You Need to Know About Charging the iPhone 12 and 13

The latest Apple iPhones don’t ship with a power adapter, but they do support Apple’s wireless MagSafe charging. Whether you use a cable or not, these are the fastest ways to charge the iPhone 12 and iPhone 13.

Starting with iPhone 12, Apple no longer includes power adapters in every box as it moves to reduce package waste (and make some cash on accessories). Its newest smartphones also include support for Apple’s magnetic MagSafe charging. Here’s what you need to know about charging your iPhone 12 and iPhone 13, and what you might need to purchase.

What Comes With the iPhone 12 and iPhone 13?

Every iPhone 12 and iPhone 13 comes with a USB-C-to-Lightning cable, and that’s pretty much it. So out of the box, those who don’t currently have any Apple power adapters will need a USB-C power adapter to charge the iPhone 12 and 13.

Plus, the newer iPhones ship without EarPods, so you’ll need to supply your own headphones to listen to music and podcasts. Apple sells its own AirPods wireless earbuds, but there are plenty of alternatives that won’t break the bank, not to mention our picks for best wireless headphones and those made with runners in mind.

As Apple explained during its iPhone 12 event last year, excluding the power adapter reduces the size of the box. This means 70% more devices can fit on a shipping pallet, which means more iPhone 12 devices can ship to users. Smaller boxes also allow Apple to reduce yearly carbon emissions by 2 million metric tons, it says.

How Do I Charge the iPhone 12 and iPhone 13?

Apple has not fully transitioned the iPhone to USB-C—which typically provides faster charging speeds—or removed ports altogether, so the iPhone 12 and iPhone 13 still include the typical Lightning charge port. This means you can use an existing Lightning cable and traditional USB-A power adapter to charge both phones. With the included USB-C-to-Lightning cable, though, you can also plug your iPhone into your Mac laptop.

Additionally, the iPhone 12 and iPhone 13 are compatible with current Qi wireless charging pads. However, Apple’s main focus for charging the iPhone 12 and 13 is its built-in, fast charging MagSafe magnetic power connector.

What Is MagSafe?

For years, Apple used the term MagSafe to describe its computers’ charging cable connectors. Their magnetized tips “snapped” into the magnetized MacBook charging ports—and snapped out if disturbed so as not to bring a Mac laptop crashing to the floor, for example. They disappeared a few years ago as Apple transitioned the MacBook lineup to USB-C charging and data transfer, but returned this fall in the M1 Pro/M1 Max-based MacBooks as «MagSafe 3.»

Apple brings a similar technology to the iPhone 12 and iPhone 13 lineup in the form of a magnetized “hockey puck” disc that looks like a big Apple Watch charger and snaps to the rear of the phone. This MagSafe connector includes a USB-C cord that plugs into a power source and charges at 15W.

What’s the Fastest Way to Charge the iPhone 13?

Since iPhone 5, Apple has shipped its iPhones with a 5W USB power adapter in the box, with the exception of the iPhone 11 Pro and Pro Max, which ship with an 18W USB-C power adapter. (Apple’s iPads also ship with 10W or 12W USB or 18W or 20W USB-C power adapters, depending on the model.) So unless the iPhone 12 or iPhone 13 is your first Apple device, you probably have one of them lying around.

MagSafe: Everything About Apple’s iPhone Charging Technology

With the iPhone 12 and 12 Pro models introduced in October 2020, Apple reinvented «MagSafe,» a name once used for the breakaway magnetic charging cables designed for the MacBook. The repurposed ‌MagSafe‌ name still pertains to magnet-based accessories, but this time, designed for iPhones rather than Macs.

All of the ‌iPhone 12‌ and iPhone 13 models have a ring of magnets built into the back around the wireless charging coil that adhere to ‌MagSafe‌ based accessories like cases and chargers, and this guide outlines everything you need to know about ‌MagSafe‌.

How MagSafe Works

‌MagSafe‌ uses a ring of magnets in the ‌iPhone 12‌ models to connect to accessories that also have magnets built inside. So, for example, Apple’s ‌MagSafe‌ Charger snaps right on to the back of an iPhone, much like a magnet snaps onto a refrigerator.

Cases are the same way, snapping onto the magnet ring built into the ‌iPhone‌. The design of the magnet ring allows the ‌iPhone 12‌ models to be compatible with a whole range of accessories that rely on magnets, from chargers to mounts to cases.

The Magnet Ring Inside iPhones

‌iPhone 12‌ and ‌iPhone 13‌ models have a ring of 18 rectangular magnets arranged in a circular shape located underneath the wireless charging coil in each device, which is what allows the ‌MagSafe‌ magic to happen.

MagSafe Charger

The ‌MagSafe‌ Charger looks something like a larger Apple Watch Charging Puck with an aluminum body and a soft white material at the top of the charger. The charger snaps onto an ‌iPhone‌ with magnets inside, perfectly aligning the charging coil in the ‌MagSafe‌ Charger with the charging coil in the ‌iPhone‌.

Apple has also designed the MagSafe Duo Charger, which combines a ‌MagSafe‌ charger with an Apple Watch charging puck. The charger is foldable, making it ideal for travel, and costs $129.

The ‌MagSafe‌ Duo Charger is not able to charge an ‌iPhone 12‌ at the full 15W. With Apple’s 20W charger, the ‌MagSafe‌ Duo chargers at a maximum of 11W, and with a 27W or higher USB-C power adapter, it charges at up to 14W. The ‌MagSafe‌ Duo does not come with a power adapter and a charger must be purchased separately. Note that the 29W charger from Apple is not compatible, but the 30W version is.

12W Charging for iPhone 12 and 13 mini

For most of the ‌iPhone 12‌ models, the ‌MagSafe‌ charger is able to charge at a maximum of 15W, but for the smallest ‌iPhone‌, the iPhone 12 mini, charging maxes out at 12W. The same goes for the ‌MagSafe‌ Duo. Charging speeds can also be affected by the temperature of the ‌iPhone‌.

Getting 15W Charging Speeds

Achieving 15W (or 12W on ‌iPhone 12‌/13 mini) charging speeds requires Apple’s 20W power adapter or another appropriate 20W+ PD 3.0 charger. Testing with Apple’s prior-generation 18W iPad charger and a 96W MacBook Pro charger proved that those power adapters do not allow the ‌MagSafe‌ Charger to reach the full 15 watts.

The same goes for many existing third-party power adapters, which also do not have the proper charging profile. New chargers from third-party companies may, however, include support for the ‌MagSafe‌ Charger, and testing indicates that to provide the 15W charging speed, a ‌MagSafe‌ Charger needs to support Power Delivery 3.0 at 9V/2.22A or 9V/2.56A, according to Apple. The ‌iPhone 12 mini‌ can hit maximum charging speeds with a 9V/2.03A power adapter.

You’re guaranteed to get 15W with Apple’s $19 20W power adapter (this power adapter also comes with the 2020 iPad Air models), but you may also be able to use a third-party charger as long as it meets those specifications.

MagSafe Charging vs. Traditional Charging

With the ‌MagSafe‌ Charger, it takes about an hour to charge an ‌iPhone 12‌ from zero to 50 percent, which is double the time that it takes to charge using a USB-C to Lightning cable and a 20W+ USB-C power adapter.

When the ‌iPhone‌ is warm, charging speeds can be throttled down, and Apple warns that if the ‌iPhone‌ gets too warm, charging will be limited above 80 percent. Apple recommends moving your ‌iPhone‌ and charger to a cooler location if it feels overly warm.

Charging Speeds With Lightning Accessories

When Lightning-based accessories like EarPods are connected to an ‌iPhone 12‌ model, charging with ‌MagSafe‌ is limited to 7.5W, which is something to be aware of.

MagSafe Charging Animation

When you place a ‌MagSafe‌ Charger on a compatible ‌iPhone‌, the ‌iPhone‌’s display will feature a ‌MagSafe‌ charging animation with a MagSafe-like shape on the screen along with a readout of the current ‌iPhone‌ charge.

Using the MagSafe Charger With Older iPhones

Using the ‌MagSafe‌ Charger with older iPhones is possible, but not recommended because charging is slower than with the 7.5W Qi-based chargers. Charging appears to be capped at right around 5W with the ‌MagSafe‌ Charger when paired with older devices, and in testing, the ‌MagSafe‌ charger has proven to be slower than using a plain old Qi charger.

MagSafe vs. USB-C

Testing suggests the ‌MagSafe‌ Charger charges a compatible ‌iPhone‌ less than half as fast than a wired 20W USB-C charger. With the 20W charger, a dead ‌iPhone‌ was able to charge to 50 percent in 28 minutes, and the same 50 percent charge took an hour over ‌MagSafe‌.

MagSafe Cases and Accessories

Apple has designed cases, wallet attachments, and a ‌MagSafe‌ Charger to use with the ‌MagSafe‌ iPhones, and third-party case and accessory makers are also creating MagSafe-compatible products. We have a guide highlighting some of the available MagSafe accessories that you can purchase.

MagSafe Don’ts

• Avoid putting single use cards like hotel cards against the magnet in the ‌iPhone‌ or the ‌MagSafe‌ Charger
• Don’t put credit cards, security badges, passports, or key fobs between the ‌iPhone‌ and ‌MagSafe‌ Charger because magnetic strips and RFID chips can be damaged
• Don’t charge with the ‌MagSafe‌ Wallet attachment on the ‌iPhone‌ (cases can remain on)

MagSafe Charger Warnings

When using the ‌MagSafe‌ Charger, Apple warns that it can leave an imprint on the Leather Cases designed for ‌MagSafe‌ iPhones, which is something to be aware of. It can also leave a mark on Silicone cases based on reports from MacRumors readers, and it’s possible that this will affect third-party cases made from soft materials as well.

Apple recommends that those worried about the ring that can be caused by ‌MagSafe‌ choose Silicone or Clear cases instead of the Leather versions.

MagSafe and Pacemakers

Like all iPhones, the ‌iPhone 12‌ and 13 models with their ‌MagSafe‌ technology can cause interference with medical devices like pacemakers and defibrillators. Apple recommends keeping ‌iPhone 12‌ models and all ‌MagSafe‌ accessories a safe distance away from implanted medical devices.

A safe distance is considered more than 6 inches / 15 cm apart or more than 12 inches / 30 cm apart if wirelessly charging. Though there are more magnets in the ‌iPhone 12‌ models, Apple says that they are «not expected to pose a greater risk of magnetic interference to medical devices than prior ‌iPhone‌ models.»

Cleaning the MagSafe Charger

Apple recommends cleaning the ‌MagSafe‌ charger with a soft, lint-free cloth. Abrasive cleaning cloths need to be avoided, as do cleaning agents. Apple recommends against excessive wiping, which could cause damage, and says that bleaches and aerosol sprays shouldn’t be used.

‌MagSafe‌ Chargers can be disinfected with a 70 percent isopropyl alcohol wipe or a Clorox Disinfecting Wipe, as long as no moisture gets in any openings.
