How to improve call quality on iPhone
Enable VoLTE feature
VoLTE is a feature equipped by Apple for the iPhone to convert call data from traditional networks over LTE connections. This is a useful way to improve poor call sound quality on iPhone.
To activate this feature, you just need to 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 highest quality sound. But, this feature will often reduce call quality. So to improve call quality on iPhone in some cases, turn it off. Go to “Settings” select “Accessibility” Select “Noise Cancellation” and turn it off.
Hold iPhone properly
In case the call sound quality is not good, change your phone holding position. Grasp the bottom edge and hold the phone close to your ear to keep your fingers away from the mic and speaker. Sometimes simple changes work really well.
Check the back cover
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 please remove the case, it will help improve the sound quality of calls significantly.
Reinstall connection
You can also try Resetting the connection to improve call quality. To do this, you just need to go to Settings -> select "General" select "Reset" select "Reset Network Settings".
Move to another location
Sometimes calls have poor sound quality due to a poor network connection. So you can move to another location with better connection quality. Especially with large buildings, interference often occurs, causing poor sound quality.
Volume up
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 a call is received even though the volume is turned on, there is still no improvement, turn on the speakerphone to make the volume louder and easier to hear. And if after turning on the external speaker the sound quality still does not improve, the cause may be due to the connection. And now you check to see if the current connection is good.
Check if the speaker is dirty or not
The speaker and mic are designed as small holes so they are often susceptible to dust and dirt. So the sound quality often gets worse. To fix this, check to see if the speaker is dusty and clean it thoroughly.
Update and reboot
And after you've done all the above steps and still haven't improved call quality on your iPhone, check for the operating system update. If not, update and restart iPhone. If after doing all the above methods the condition does not improve, bring your device to an Apple center to have it checked or buy a new one to use.
