Frequent users of AirPods Pro should be familiar with the noise reduction features that come with this headset.
When you're in a noisy environment, simply turn on noise cancellation mode to eliminate the noise around you and use your headphones more immersively.
What many friends may not know is that the iPhone in your hand actually comes with noise reduction.
From iPhone 5 to iPhone 12, this feature is designed to help users reduce noise interference during calls.
We can find the "Phone Noise Cancellation" function through "Settings" - "Accessibility" - "Audio/Visual" and select to turn it on or off.
When turned on, when a user uses an iPhone to call, it will reduce the ambient noise during the call and improve the quality of the call.
In the newly released iPhone 13 series, this feature is absent.
According to netizen feedback, the "phone noise reduction" switch could not be found in the iPhone 13, and this problem has been going on for more than two months.
Taking the iPhone 13 Pro in Xiaoguo's hand as an example, after entering the "Audio/Visual" settings page, the "Phone Noise Reduction" option under "Mono Audio" is indeed missing.
In fact, as early as October this year, there was user feedback that they did not find the call noise cancellation function in the settings of the iPhone 13.
In the iPhone user manual on Apple's official website, after selecting the iOS 15 system version, you can still find an official description of this function.
It can be seen that the iOS 15 system supports this function, and the iPhone 13 series with the iOS 15 system should also have this function.
A user with the iPhone 13 said he had been discussing the matter with Apple's support department, which Apple reported was a known issue and was working to resolve it, but there was no timetable for resolving it at the moment.
This issue has not been resolved in either the previously released iOS 15.2 release or the iOS 15.3 beta system released 10 days ago.
Although this issue has not yet been resolved, iPhone 13 users can also use another feature to improve call quality.
Released this year in the official version of iOS 15, Apple has added a series of features to the FaceTime app.
For example, "Simulcast Sharing", users can watch movies, listen to songs or share screens with friends through FaceTime.
In addition, Apple has also launched a "voice highlight" function.
With this feature, users can eliminate surrounding noise and improve call quality when making FaceTime calls.
In FaceTime, we can pull down "Control Center", click "Microphone Mode" in the upper right corner, and select "Voice Highlight".
Judging from the current feedback from the outside world, the lack of call noise cancellation function of iPhone 13 may be caused by the system bug of iOS 15, not the hardware problem of iPhone 13 itself.
Hopefully, Apple can solve this problem once and for all through subsequent software updates.
