What you need to know

  • Apple will put iPhone 12 mini up for pre-order this Friday, November 6.
  • It's updated a support document to include information about using a MagSafe Charger with the miniature iPhone.
  • Turns out the MagSafe Charger can only charge iPhone 12 mini at 12W.

In news that will surely be a disappointment to those planning on picking one up, Apple says that the MagSafe Charger will only charge iPhone 12 mini at up to 12W. That's strange because the rest of the iPhone 12 and iPhone 12 Pro lineup all support 15W charging.

The news comes after MacRumors spotted a newly updated support document (opens in new tab) that outlines the speeds at which a MagSafe Charger can do its thing. And it isn't great reading for those buying Apple's smallest iPhone 12.

The MagSafe Charger is designed to quickly and safely wirelessly charge your iPhone 12. The system intelligently adapts to conditions in order to optimize charging iPhone 12 at up to 15W of peak power delivery for faster wireless charging. The actual power delivered to the iPhone will vary depending on the wattage of the power adapter and system conditions. For iPhone 12 mini, the MagSafe Charger delivers up to 12W of peak power delivery.

Apple doesn't go on to explain why that might be, which is a real shame. We might have to wait until someone tears one of these things down to see what's going on inside. But if I had to guess, it could be related to the size of the device and potential cooling issues. But again, that's my wild guess,

Regardless of the reasons, it's pretty bad news for anyone buying an iPhone 12 mini this week. And don't forget you're still going to need a charger as well!

  • It would make sense that thermal considerations and potentially the size of the coil in the Mini could limit the transfer capability. Still probably faster than the typical 7.5W or 10W.
