iPhone 12 Pro charging slowly with Magsafe charger

I bought the MagSafe charger with the 20w brick this week and have been used to charging the iPhone XS, it’s noticeably slower as usual since it’s not compatible.


But my iphone 12 pro arrived today and added my MagSafe clear case and have been using the MagSafe charger with the 20w. It was a 61% battery right at 4:00pm, when I checked at 4:30, it was sitting a 64%. I thought it was supposed to 15w superfast charge, am I missing something? Is it a Hardware defect, is it the MagSafe case? If i use my 20w usbc to usb lightning it would have been at 90% within that time frame, maybe my expectations were high, but even then the phone feels super hot to touch.


Everything’s apple branded.

So to recap Iphone 12 pro, with apple MagSafe clear case, with the MagSafe clear charger for the 12 pro and the newly released 20w power adapter. I used all of these and have noticed it’s still slow, ****, my Apple Watch series 6 reached a 100% before the phone did.

I’m glad that I’m not alone. Got my iPhone 12 pro and the MagSafe charger 2 days ago, and used the MacBook 65W charger to charge my 12 pro without the case. After 20mins, the battery only went from 19% to 20% in 20 mins of charging. I switched to lightning charging and it worked fine.

Anyway, I’m meeting a Genius tomorrow and will bring my phone and MagSafe for inspection.

so due to heat concerns it does lower the wattage over time... i’ve found to help reduce this, not completely get rid of it because that would be dangerous, turn off optimized charging. Again this doesn’t fix it but it does help, also i’d recommend using a normal cable to charge throughout the day, or if you don’t need your phone at the current time use the magsafe, or if your just looking for a little bit of power to get you through the day. This charger, without optimized charging, will get it to 100% overnight, but during the day you will find after about 20-25% it gets noticeably slower.

That’s all nonsense. The phone is much better at protecting itself than you are at attempting to protect it. The absolute best thing to do for the phone is to enable Optimized Charging and charge the phone overnight, every night. If you do this there’s no real advantage to fast charging, but it won’t hurt, either. If the battery is low during the day (which is unlikely unless you are a very heavy user of interactive games or make long phone calls with a weak cell signal) you can fast charge it for a half hour (which will bring it to at least 50%).

I bought iphone 12 Pro in Jan and within first 10 days, i raised the same issue with customer support and since then i have been visiting apple store but of no use. Phone takes much longer time to charge and when i asked for phone replacement, they are refusing to replace even i had raised the issue in the first 10 days only. Lot of time being wasted without any proper support. This is the prize apple is paying to its loyal customers.

Go to Settings/Battery/Battery Health. Is Optimized Battery Charging turned on? If it is the phone is supposed to stop at 80% if you charge it over night (and you should), then resume automatically to reach 100% at the start of your day after it learns your usage pattern. If you don’t plan to charge overnight turn off this feature.


It will also stop at 80% to cool off if you fast charge it; then it resumes at a much slower charge rate to avoid overcharging. It can take an additional hour or two going from 80% to 100%.
