In the field of mobile phones, Apple is almost all high-end consumer groups can not avoid the topic, in addition to the performance of the explosive A series of chips, rich and safe application ecology, the most important thing is Apple's smooth, closed IOS system. Unlike Android manufacturers, Apple has an exclusive camp, the system has a high "customization" ability, and Apple cares very much about the user's experience, plus some system repairs and other issues, so we can see that Apple's IOS system updates are more frequent than Android, but frequent overturning and new features are constantly presented, so that many fruit fans love and hate Apple's IOS system.
However, the functionality brought by Apple's recent update has exploded in the digital field! On March 15, Apple's IOS15.4 official version was officially pushed, which is the fourth major version update since the release of IOS15, the installation package size is about 1.28GB, not only some bugs have been fixed, but also for the iPhone 12 and subsequent models to bring new and extremely useful features.
Judging from the information pushed by IOS15.4, the most important function is the "wear mask to unlock" function, iPhone12 and subsequent models after upgrading IOS 15.4, even if wearing a mask, can also be unlocked through face ID. This is indeed a very practical function for us under the haze of the epidemic, allowing us to take off the mask before taking out the mobile phone payment in public, reducing the risk of being infected by bacteria and viruses, compared with the entire mobile phone industry, it is indeed a technological innovation. In addition, the ioS 15.4 update also brings new "emojis", the ability to synchronize sharing sessions directly from supported apps, etc.
According to the usual experience, although the update of the large version will bring some innovative features, it may also cause losses in terms of performance, endurance, etc., so in the face of the update of IOS 15.4, I believe that many fruit powders still hold a "wait-and-see" attitude, so fruit powder do not rush to upgrade first, and then make a decision after reading the first batch of user reviews!
First, in terms of "wearing a mask to unlock", many netizens have reported that the accuracy rate of face recognition after upgrading to IOS 15.4 is very high, especially in the case of increasingly serious public health problems, this function is very useful. However, this function is not a panacea, if the user wears transparent glasses, the unlock success rate is really good, but when the user wears sunglasses, this function is Barbie Q, basically 100% can not be unlocked. Because this function is certified by scanning the unique features of the user's eye area, the sunglasses cover the eyes, which is equivalent to obscuring the key areas of the certification.
Second, the system is smoother. Some netizens said that after the update, especially after the iPhone12 user update, the storage was less than five or six G, but in the sliding process, there was almost no phenomenon of frame drop, and the animation display was smoother and more silky. And after upgrading IOS 15.4, the situation of WeChat caton has also been improved.
Third, the temperature control ability is better. Many netizens said that iPhone13Pro in the absence of updates before playing "Peace Elite" is easy to be hot, after updating to IOS15.4, the fever problem has been significantly improved, at most just warm, and feel that the power loss speed is not as fast as the original, even if you turn off the "power saving mode", in the case of long-term brushing video, keep the screen on, you can obviously feel that the battery life has improved, and the screen will not be hot.
Fourth, the signal has improved. In the case of weak display signal before the upgrade, in the same position after the upgrade, the signal display is raised by one block or directly reaches the full grid, and the playback will not spin when watching short videos or movies, and it can be clearly felt that the signal connection between the mobile phone and the base station is more stable.
Judging from the feedback from the fans who have upgraded IOS 15.4, most of the reviews are positive, which also proves that IOS 15.4 is indeed "positive optimization" and does not roll over. In particular, the function of "wearing a mask to unlock", for us in the current environment, it is indeed from the perspective of consumers to carry out technological innovation, fruit powder does not need to hesitate, early upgrade and early enjoyment!
