Apple has launched a MagSafe charger that is compatible with the iPhone 12 series, and the official support document on how to use it has been released.

One of the most eye-catching sections of the document warns that "if you keep your iPhone in a leather case while charging with your MagSafe Charger, the case might show circular imprints from the contact." At the time of writing, we don't see any leather cases in Apple's MagSafe-compatible accessory list, but a small mention in the iPhone 12/12 Pro release notes says, "iPhone 12 Leather Case will be available beginning Friday, November 6."

Already, one of MacRumors reader has reported a circular imprint on Apple's original MagSafe-compatible silicone case as well. This is probably unavoidable as the magnets on both sides of the iPhone 12 and MagSafe attract each other with considerable force, but the warning was presumably issued as it may be more pronounced in a leather case.


The support document also reveals some other interesting information about MagSafe.

  • Don't place credit cards, security badges, passports, or key fobs between your iPhone and MagSafe Charger, because this might damage magnetic strips or RFID chips in those items. If you have a case that holds any of these sensitive items, remove them before charging or make sure that they aren’t between the back of your device and the charger.

  • As with other wireless chargers, your iPhone or MagSafe Charger might get slightly warmer while your iPhone charges. To extend the lifespan of your battery, if the battery gets too warm, software might limit charging above 80 percent. Your iPhone or MagSafe Charger could get warmer and charging could take longer after heavy use. 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 simultaneously connected to power via the Lightning port—instead, your iPhone will charge via the Lightning connector.

The "How to clean your Apple products" page has also been updated to include instructions for cleaning the MagSafe charger. The document says that because MagSafe Charger contains magnets that might attract debris during everyday use, you should brush off any debris from the metal ring before cleaning this accessory. Unplug your MagSafe Charger from power. Then use a soft, slightly damp, lint-free cloth to wipe the silicone middle of the charging area.

It is followed by not window cleaners, household cleaners, aerosol sprays, solvents, ammonia, abrasives, or cleaners containing hydrogen peroxide to clean MagSafe Charger.

Because of the use of magnets for alignment, it's best to avoid putting credit cards, especially those with magnetic stripes, close to the iPhone 12. (Apple executives have admitted this in interviews.) If you're going to carry your iPhone 12 series and credit cards with you, you'll want to buy Apple genuine leather wallet case with magnetic shielding.
