MagSafe Fast Charging Won’t Damage Your iPhone 12 Battery

With the right charging brick, Apple’s MagSafe charging pad can quickly charge your iPhone 12 at an estimated 50% battery in 30 minutes. Although it was written last year, Clifford Colby’s article is a helpful investigation into fast charging. The short answer is that fast charging won’t damage your iPhone’s battery.

Damage is rare if everything’s well-managed inside. A battery’s management system closely monitors the two charge phases and drops the charging speed during the second phase to give the battery time to absorb the charge and avoid issues, which is why it can take 10 minutes to get those last few percentage points.
