iPhone 12 and iPhone 12 Pro finally have support for 15W wireless charging, thanks to the new MagSafe feature. However, Qi wireless charging still works at 7.5W. Confused? Read on to find out what is new in MagSafe wireless charging and how is it different than Qi.

MagSafe is an old brand name for Apple, which was used in the past for MacBook chargers. The chargers used magnets to allow cables to disconnect without any force, to ensure that MacBooks do not fly away from the desk if someone accidentally yanks the charging cable. With iPhone 12 and iPhone 12 Pro announcements today, Apple announced its new MagSafe wireless charging which works with specific accessories that work with the magnets placed inside the iPhone, for the best positioning. This improved alignment due to the wireless chargers allows for a new ecosystem of accessories, one of which is a new MagSafe Charger.
