Apple's epic upgrade, iOS 15.4 has arrived.

Years ago, I thought the mobile phone circle would be dull. I didn't expect Apple to bring you another "bomb", that is, the version of iOS 15.4 beta 1, which brought you the long-awaited faceID with a mask!

First of all, Apple's iPhone is a smart phone that many people like. This is because Apple's iPhone experience is good, thanks to Apple's deep grasp of IOS and A-series chips.

Therefore, Apple dares to provide a five-year system update for each iPhone, which other mobile phone manufacturers can't do.

However, in 20021year, Apple introduced the IOS 15 system, which obviously didn't add any new functions. The following IOS 15. 1, IOS 15.2, and IOS 15.3 systems are also the same, focusing on repair and optimization.

Unexpectedly, Apple officially announced the IOS 15.4 system and launched a new beta version. In this version, Apple has added a new face recognition technology, which can recognize faces even when wearing a mask.

This means that in the official version of IOS 15.4 system, Apple will also officially support wearing masks for face recognition, especially in the current environment, this function is particularly practical.

Last year, Apple added users wearing masks to the iOS 14.5 version, which can be unlocked by smart watches when wearing Apple Watch. However, although everyone has a mobile phone, not everyone will choose to buy Apple Watch, so this function is like pushing loneliness.

But unfortunately, wearing a mask for face recognition will only be aimed at iPhone 12 series and iPhone 13 series, and other models of iPhone will not support this function.

So so far, if you want to experience this new function, you need to meet two conditions at the same time:

1. The phone model must be iPhone 12 series or iPhone 13 series.

2. The system version must be upgraded to the developer version of iOS 15.4. After upgrading to the development version of iOS 15.4, you can see the entrance and selection menu of "wear a mask and use a face ID" in the welcome interface.

In the interface of setting -Face ID and password, the development version of iOS 15.4 has added the switch of "Wear a mask and use face ID". After opening it, just enter face information as prompted. In order to better capture the unique features around the eyes, the system supports adding different glasses, which is very friendly for users who need to wear myopia glasses like Minmei Unlimited. In particular, face ID does not support sunglasses because it captures the features around the eyes.

When the above operations are completed, users can easily unlock their iPhone with a mask, which is basically the same as the experience without a mask. However, when the fog on the glasses is too heavy, the experience of face ID will drop sharply, and it will soon return to normal after wiping the glasses with a paper towel. Minmei Unlimited also tested the face ID payment when wearing a mask, which has perfectly adapted to Alipay and WeChat wallet, and the era of eating by face can finally pass.

Regarding whether to follow up the remaining iPhone models, Apple said that the new system is only a beta version and will be supplemented according to the actual situation when it is officially released. Now this function is for testing developers, and users who have not experienced it can wait.

In addition to the above functions, a password function has been added in the new system version, and users can use the saved password to log in password-compatible websites and applications on Macs and iPad. This means that you can use iPhone authentication on websites that allow Face ID or Touch ID authentication without entering a password.

Also, the code in iOS 15.4 shows that Apple is developing a "cosmetic scan" function, which will be used when trading the iPhone. Beauty scanning may be used to check the damage of iPhone, such as scratches and dents, to provide a more accurate evaluation of redemption value.

In iPadOS 15.4, a new keyboard brightness option can be added to the control center, allowing you to adjust the brightness and backlight of the connected keyboard. Wonderful keyboard for Apple, but it really needs to be added to the control center by going to Settings >; Control Center, click the "+"button next to the keyboard brightness.

In addition, support the new 5G frequency band: Will the 5G signal change in iOS 15.4? According to feedback from netizens, the beta version of iOS 15.4 officially supports the 700MHz band of China Mobile N28 5G, which originally belonged to China Radio and Television, and was later applied by China Mobile to share with Radio and Television.

Compared with other 5G bands, the frequency of 700MHz band is lower, and the signal coverage of a single base station is wider, so the 5G signal will be better under the same conditions. If you use China Mobile's 5G and are equipped with iPhone 12 and 13, upgrade to iOS 15.4 system, you will find that the 5G signal will be much better than before.

In addition, it is worth mentioning that Minmei is infinite today. According to Christian Selig, the developer of Apollo, Apple's iOS 15.4 beta has also solved another big problem, that is, it supports the promotion technology, which makes iPhone 13 Pro and iPhone 13 Pro Max support the promotion of high refresh rate of 120Hz.

You know, although iPhone 13 Pro and iPhone 13 Pro Max both support the promotion of 120Hz, due to the lack of substantial progress in the adaptation of third-party applications, most apps are still limited to the low refresh rate of 60Hz, and the advantages of new devices with high refresh rate of 120Hz cannot be brought into play. With the arrival of iOS 15.4 system, fruit fans can finally experience the pleasure of 120Hz high refresh rate. Are you ready to update your iPhone 13 Pro version?

Now go to Apple's official flagship store in JD.COM, start with the new iPhone 13 Pro Max, and enjoy the 12 interest-free period &; 30-day price guarantee! Buy "fast charging set" and add 99 yuan to get 20W fast charging head! If you want to experience the unlocking function of wearing a mask and the pleasure of 120Hz high refresh rate, you can try one.

In addition, by the way, Minmei Unlimited still has some minor problems on iOS 15.4 today. Minmei Unlimited WeChat official account fans made a summary, mainly focusing on APP flashback. The current bugs of iOS 15.4 are summarized as follows:

1, Baidu map can't stay in the background.

2, Baidu Post Bar slides, some jams are not smooth.

3. The salted fish app will flash back.

4. WeChat reading app will flash back occasionally.

5. After the restart, the screen brightness appears dark for several seconds.

6, wearing a mask to unlock is slow and cannot be unlocked in seconds.

7. WeChat voice message turns around.

8. The details of the 8.Apple Store software will slide and the frame will be discarded.

9. Pocket League of Legends app flashes back.

And the experience feedback of fruit powder is as follows:

1. The endurance performance is very satisfactory, and the standby power consumption at night is only 2%. I remember that the previous iOS 15.2. 1 was 3-4%.

2. The system is much smoother. Before the transition animation, there was a feeling of falling frames and incoherence, and now it is really normal.

3. In terms of signal, iOS 15.2. 1 occasionally fails to receive a signal of 5, and occasionally there is no signal problem. Upgrading 15.4 can't be said to completely solve the signal problem, but it does improve a lot.

4.4. The problem of WiFi disconnection has also improved.

5. I really can't go back after unlocking with a mask. I have tried many times and the recognition rate is 100%. I really like apples.

6. The problem with the speaker button has been fixed.

7. Run geekbench5 after the upgrade, and the single-core and multi-core scores have improved a little. Although running score does not represent experience, it does improve performance and fluency can be reflected.

8. When the mobile phone is plugged in, the calorific value is a little higher than the previous version. Maybe it's a beta. I hope the official version can be improved in the future, and the fever in the game is similar to that in the previous version.

9. The battery health value has not changed.

10. There are still software compatibility problems. I hope that the third-party software can be updated in time, and I hope that the official version of iOS 15.4 will be better in the future. Let me support the elderly.

To sum up, the most discussed version of 15.4 is the faceID function of wearing a mask. Tell me about my experience.

The model is iphone 13. Although I have apple watch in my hand, I am looking forward to this new feature. After the upgrade, I still admire Apple. The principle behind the seemingly simple function is still very complicated.

Minmei's infinite personal guess is that Apple adjusted the angle of structured light and concentrated the projected lattice on the top of the face or near the glasses, so this function is mainly realized by software algorithms.

This is why Apple only added this function to iphone 12 and 13, because it would consume a lot of computing power of the processor and increase the burden and power consumption of the processor, but I didn't feel any increase in power consumption after using it for two days.

Speaking of power consumption, the battery life did collapse a little after the upgrade, but it has returned to normal after two days of use. I don't think it is much different from the official version of 15.3. If your battery life drops after the upgrade, I suggest you try it for a few more days.

Upgrade suggestion

This time, iOS 15.4 Beta mainly adds the functions of wearing a mask and using face ID, and there are not many new changes. The small partners who are still in the official version do not need to upgrade first. If they urgently need to wear the mask face unlocking function, they can upgrade by installing the description file.

Finally, if you have anything to say about Apple's epic iOS 15.4 upgrade, please leave a message in the comment area to let Minmei participate in the discussion!
