Due to the performance of the Qualcomm Snapdragon 888 last year, the iPhone 13 series released by Apple has become one of the few flagship phones that can be regarded as a comprehensive upgrade in performance and power consumption. However, since the release of the iPhone 13 series, many users have reported that the iPhone 13 series can not find the call noise reduction function, and Apple's official technical staff has confirmed that the iPhone 13 series has disabled this function, but the official did not give a specific reason for disabling the function.
According to Apple's official description of the call noise reduction function, this function is mainly to allow users to get a clear call effect in a relatively noisy environment, but the strange thing is that in addition to the iPhone 13 series, other iPhones still retain this function after the system update, even if the previous iPhone 12 and iPhone 12 Pro products that have had handset problems also retain the call noise reduction function, Apple's operation, it seems to make people feel a little confused.
In view of the fact that the entire iPhone 13 series has removed this function, it can be expected that subsequent iPhone models will not be equipped with this function as standard, if you must call in a noisier environment, perhaps only the AirPod Pro with noise reduction can solve this problem.
