Initially, MagSafe was a detachable charging port seen on apple's MacBooks. Circular, magnetic coils were included in each iPhone 12 model by Apple, which revamped the technology for the launching of the iPhone 12.
Your device will then have continuous battery life thanks to this coil's ability to latch onto peripherals like Apple's MagSafe Battery Pack. This means that you do not require a battery cover, assuming you like having a block linked to your iPhone to be a positive thing.
Do all iPhones have MagSafe?
Some MagSafe accessories will function with the iPhone 11, but not all. Like the iPhone 12, it has a wireless charging ring, although it is not magnetic.
This implies that if you want an iPhone with MagSafe, you must either get an iPhone 12 – regardless of the model – or wait until Apple's new iphone 13 is released in the latter part of 2021.
Since they attach easily to the back of the iPhone, MagSafe can also be used with wireless charging docks. Similar to cases and a number of other iPhone accessories.
