How to Improve Call Quality on iPhone
Enable VoLTE feature
VoLTE is a feature that Apple equipped for iPhone to convert call data from traditional network to LTE connection. This is a useful way to improve the situation of poor call sound quality on iPhone.
To activate this feature, just go to "Settings", select "Cellular", select "Cellular Data Options", turn on LTE network and finally turn on the "Voice & Data" option.
Turn off noise cancellation
One of the great features of the iPhone is noise cancellation and noise filtering to create the clearest and best sound. However, this feature will sometimes reduce the quality of calls. So to improve the quality of calls on the iPhone in some cases, you should turn it off. Go to “Settings” select “Accessibility” Select “Noise Cancellation” and turn it off.
Hold iPhone properly
If the call quality is not good, change the way you hold the phone. Grip the bottom edge and hold the phone close to your ear so your fingers are away from the mic and speaker. Sometimes simple changes can make a big difference.
Check the case
If you are using a phone case and it is quite bulky, this is one of the reasons why the call connection is interrupted and the signal is disturbed. So you should remove the case, it will help improve the sound quality of the calls significantly.
Reset connection
You can also try resetting the connection to improve call quality. To do this, simply go to Settings -> select “General” select “Reset” select “Reset Network Settings”.
Move to another location
Sometimes poor call quality is due to poor network connection. So you can move to another location with better connection quality. Especially with large buildings, there will often be interference that causes poor sound quality.
Increase the volume
An extremely simple way to improve call quality on iPhone is to increase the volume. Then the sound in the conversation will be louder and clearer.
Turn on speakerphone
If the call received does not improve even though the volume is turned up, you should turn on the speakerphone to make the volume louder and easier to hear. And if after turning on the speakerphone, the sound quality is still not improved, the cause may be the connection. And at this time, you check if the current connection is good.
Check the speaker for dirt
The speaker and microphone are designed with small holes so they are often easily clogged with dust. Therefore, the sound quality often becomes worse. To fix this, check if the speaker is dirty and clean it thoroughly.
Update and restart
And after doing all the above steps but still not improving the call quality on iPhone, you should check for operating system updates. If not, update and restart iPhone.
