Hello castle_dweller,

Thank you for reaching out to Apple Support Communities, and we'll be happy to help in any way we can. We understand you're having issues with using your MagSafe charger. Try the steps here to see if they resolve the issue: How to use your MagSafe Charger with iPhone 14, iPhone 13, and iPhone 12 models - Apple Support

• "Your MagSafe Charger is designed for faster and most efficient charging with iPhone 14 models, iPhone 13 models, iPhone 12 models, and Apple MagSafe accessories.
• When charging a non-MagSafe Qi-compatible device with a MagSafe Charger, power is reduced and charge times may be slower than on a typical Qi charger. 
• 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.
• If your iPhone is connected to both a MagSafe Charger and power via a Lightning port, your iPhone will charge via the Lightning connector.
• 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. 
• If you keep your iPhone in a leather case while charging with your MagSafe Charger, the case might show circular imprints from compression of the leather. This is normal, but if you’re concerned about this, we suggest using a non-leather case.
