The iPhone 12 and iPhone 12 Pro are finally available. As usual, Apple has updated some support pages, including one about MagSafe. Now we know – it can leave marks.
Apple has now published a comprehensive support article on the topic of MagSafe chargers. In it, the company explains that MagSafe requires at least a 12W power adapter. This means that the brand new 20W adapter is not absolutely necessary, unless the user wants to enjoy the full performance. In that case, the MagSafe would have to be operated with the new 20W charger. Otherwise, longer charging times have to be accepted. The Cupertino-based company notices Please note the following safety instructions:
- Do not place credit cards, security badges, passports, or key chains between your iPhone and the MagSafe Charger, as this could damage any magnetic strips or RFID chips in these items. If you have a case containing these sensitive items, remove it before charging or make sure it is not between the back of your device and the charger.
- As with other wireless chargers, your iPhone or MagSafe Charger may get a little warmer while your iPhone is charging. To preserve the life of your battery, the software may limit charging to 80 percent if the battery gets too warm. Your iPhone or MagSafe Charger may get warm and take longer to charge after heavy use. Your iPhone will start charging again when the temperature drops. Try moving your iPhone and charger to a cooler location.
- Your iPhone will not charge wirelessly when it is also being powered by the Lightning port - instead, your iPhone will charge through the Lightning port.

iPhone 12 & MagSafe: Marks on the back of the case
But apart from the operation of the new charger, there is another point that is causing more of a stir. Apple warns that the MagSafe can leave marks on the back of iPhone 12 leather cases.
If you keep your iPhone in a leather case while charging it with your MagSafe charger, the case may have circular contact marks.
What is interesting, however, is that these prints were also found on silicone cases, as MacRumors reportedIt is doubtful whether this will improve the reputation of the new MagSafe. The charger is currently being criticized in various tests because it charges older iPhone models significantly more slowly than other Qi charging stations. Some testers have already stated that MagSafe is better in theory than in practice. The charger costs 43.85 euros from Apple - a power adapter must be purchased separately. (Image: Apple)
