iOS 15.4 official version of the release time is earlier than expected, before the author has talked about the iOS 15.4 beta version, now the official version is coming, fruit powder can be decisively upgraded, below we first come to iOS 15.4 official version in the end what update points.
First: Support wearing a mask to unlock
Although the weather has warmed up, the "mask" behavior around the world and the whole country is still quite serious, so the unlock function of wearing a mask is also very practical. Using Face ID when wearing a mask, the iPhone can authenticate the features around the eyes to complete the unlocking.
Unconsciously, the "mask" behavior has continued for 3 years, compared with Android mobile phone users, the face ID recognition function of the iPhone phone has been complained about by many users, in the current situation, the face recognition unlock function seems to be inferior to the fingerprint unlock, as the iPhone mobile phone users are often troubled by this. Every time, you have to take off the mask to unlock it, or enter a digital password to unlock it successfully, which is very tedious.
Users who have started the iPhone12 Pro Max or iPhone13 Pro Max are even more troublesome, the phone is large and heavy, and it is difficult to operate with one hand. If you still have a heavy object in your hand when unlocking, but you need to enter the password with both hands to unlock, I believe most people will be very irritable.
Therefore, in the author's opinion, iPhone12 and iPhone13 series users, in order to wear a mask to unlock the function of this update, you can close your eyes to upgrade, after all, iOS15.4 series was originally for iPhone12 and iPhone13 series users launched, other models of users want to upgrade can not.
Second: universal control function
If you have Apple products such as iPads and MacBooks in addition to iPhones, then this function is still quite practical, and you can experience the boundaries of Apple's ecological interconnection. Under the universal control function, it is possible to achieve multi-screen interaction.
For a simple example, if I have an iPad Pro2020 and a MacBook Air device in my hand, I can share a keyboard and mouse, so my mouse can move and operate directly on the iPad Pro, and the keyboard can do the same. And the file can also be directly dragged and dropped to achieve sharing, this function is still very useful for office workers, can improve work efficiency.
Third: AirTag custom tracking and lookup
When AirTag was released before, many small partners bought Airtag for their pets, and this time iOS 15.4 was also upgraded for AirTag, adding custom tracking and search functions. This can help improve the security of users and better protect privacy. Of course, it should also be clear that AirTag is only a positioning tool, and this item cannot be used as a tool to track others, otherwise it will involve breaking the law, and Apple has also made special instructions and reminders for this item.
In summary, in the author's opinion, the biggest highlight of the official version of iOS 15.4 is still the ability to unlock the mask, but the audience of this function is limited to the iPhone 12 series and iPhone 13 series users, so if the users of other models are not necessary, it is not recommended to upgrade the iOS 15.4 system, after all, the use experience will not be too different, but may have an impact on battery life.
