When using the Battery Pack on the go, Apple says it will charge iPhone 12 at 5W. Interestingly, while the MagSafe Battery Pack does offer up to 15W charging speeds, that only happens when used while plugged into a 20W or higher power brick. Status icons also show up for the new battery pack in the Today View and widgets with iOS 14.7. Like Apple’s Smart Battery Cases, the MagSafe Battery Pack automatically starts charging your iPhone 12 when you attach it to the back of your device with a charge status showing up on the lock screen. Apple recommends charging it with a 20W or higher power adapter via the Lightning port.Īpple also recommends charging the Battery Pack fully before first use. No surprise here but the only thing in the box is the MagSafe Battery Pack itself. iPhone 12 MagSafe Battery Pack tidbits What’s in the box?
