Hey, so my girlfriend bought the new MagSafe charger and also the MagSafe case for the iPhone 12. She charged her phone overnight, but the phone’s battery was completely drained in the morning. She uses a 2018 15” MBP brick. The MagSafe charger turns hot even when the phone isn’t is charging. Did anyone here experience a similar problem? I’m trying to get to the bottom of this. Everything works just fine without a case it seems…Thanks for your replies.

I experienced that. I posted about it where I was charging overnight. Woke up at 3am and found my phone cooking a fried egg. It was super hot and I was lost a charge (can’t remember). At that point the MagSafe was so hot it stopped charging. I returned and got a replacement but I don’t know if that issue is fixed or now. I didn’t have a case. This happened one time. It usually works well.

Today I started to charge my wife’s new 12 with a MagSafe case and charger. It got hot and barely charged. I’m first chalking it up to a new phone and updating to 14.4 and indexing. I’ll see if the behavior continues or gets better in the next day or two.

Exactly and I don’t know why. She has this original Apple MagSafe enabled case with the weird circle.

it even works well with lifeproof next so im guessing it could be the magsafe or case is faulty...my magsafe sticks well and charges well.

Hers sticks well too, I don't know what's causing the issues. I tried charging my AirPods in a case and it worked flawlessly, I guess I'll try to charge my iPhone 11 Pro Max and report back.

Yeah so it charges properly just without the case. Having iPhone 12 in any case causes battery drain. What an awful product.

Checking back in from my previous post. Day 2 the MagSafe charged her phone to full overnight. I didn’t look at the battery to see how long it took. She did notice that when she would be using the phone while the MagSafe was on it would not gain any charge at all. If this thing is putting out 15W (using apples 20W briit should have no issue charging while in use like the 5W brick does wired.

Not writing off this charger yet. But these claims may be off, by a lot. Unless fast charging doesn’t work when the battery is at certain threshold?

Edit - I also read it throttles wattage based on thermal. While she was using it it was warm while charging but nothing too extreme. But even then wired on a 5W current charger the phone while in use.

We know this before but wireless charging created a lot of heat. I wonder how do android phone with faster wireless charging cope with this. Do they experience similar issues. Of course since it’s Apple #MagSafe-gate. Probably same issues I’m guessing but no one cares.
