The official version of iOS 15.4 was released, and wearing a mask to unlock the iPhone finally came.

15 At 2 am on March, Apple updated the official version of iOS 15.4, and also updated the official versions of iPadOS 15.4, macOS 12.3 and watchOS 8.5. Summarize what new features the official version of iOS 15.4 mainly brings?

Since the official version number of iOS 15.4 is the same as that of iOS 15.4 RC, users who upgraded to iOS 15.4 RC last week will not receive the official version push.

Wear a mask to unlock the iPhone.

After the iPhone 12 series and iPhone 13 series are upgraded to the official version of iOS 15.4, you can set the face ID to unlock the iPhone with a mask, and users wearing glasses can set the face ID to unlock with a mask and enter with glasses. Using face ID when wearing a mask can be used to use Apple Pay in App and Safari browsers and automatically fill in the password. This function is so convenient that you can not only unlock the iPhone with a mask, but also pay with a mask.

IOS 15.4 official version upgrade suggestion: mainly bring a mask to unlock the iPhone. This function is much needed at present, and you can also pay with a mask. I suggest you decide whether to upgrade according to your own needs. Your model does not support wearing a mask to unlock iPhone. After upgrading, it is equivalent to upgrading the version number, and there is no new functional experience. The battery life of each version is not much different. Unless your battery is in poor condition, it will only become less and less durable. The problem of fever is related to your own use and environmental impact. Fever will only get worse in summer.
