One of the key features of the iPhone 12 family smartphones, which Apple emphasized during the presentation, is support for MagSafe wireless chargers. However, as it turns out, there are several restrictions on using MagSafe. Apple itself warned users about them by updating the information on the technical support page.
If the iPhone 12 battery gets too hot, charging will stop at 80% and will only resume after the battery temperature returns to acceptable levels. Thus, it may take longer to replenish the energy reserve up to 100%.
The owners of bank cards with a magnetic stripe or RFID-chip, electronic passes, etc. run the risk of facing a problem. If such a card gets between a smartphone and a MagSafe charger, it will demagnetize and become unusable. So, as many people like to carry a card under a cover, it is clearly not worth it.
Using a leather case with MagSafe wireless magnetic charging is also not recommended. There is a possibility that circular prints will remain on the case at the place where the accessory is magnetized. The silicone case can be damaged in the same way. It is reported that in some cases, traces on it formed after just a few days of operation.
Whether MagSafe can damage the glass back of the phone over time is not specified. Over time, this aspect will also become clear. Meanwhile, replacing the back panel, according to Apple itself, costs $ 449 for the iPhone 12 and $ 549 for the iPhone 12 Pro.
