iPhone 16 Bluetooth causes increased volume for alarms and calls.

Bluetooth volume issue


Bluetooth increases the volume of alerts and alarms when using non-Apple earphones on my iPhone 16 even when volume limits for headphones and speaker are at lowest levels. 


In the Bluetooth settings, my non-Apple ear buds are classified as headphones and my external speaker is classified as a speaker. 


OTHER SETTINGS: 

A.  Screen Time > Content & Privacy Restrictions > Reduce Loud Audio > Allow 


B.  Screen Time > Content & Privacy Restrictions > Speaker Volume Limit > Allow


C.  Sounds & Haptics > Built in Speaker > Volume limit > Limit Maximum Volume > On > Maximum Limit > 40% (lowest)


D.  Sounds & Haptics > Headphones > Headphone Safety > Reduce Loud Audio > 75 decibels (lowest)


E.  The phone volume is at the lowest level. 


If I’m not using headphones or an external speaker, all volumes are appropriately low. 


However, when using non-Apple headphones or an external speaker with Bluetooth on, the volume of all alarms and phone calls are incredibly high through both.


No matter how I adjust all the settings above, the volume of alarms and phone calls is VERY loud. 


I’ve turned my phone off and on again several times, but that doesn’t help. 

This happened several months ago and I searched for help and made all the suggested changes but nothing changed the volume. Then one day the volume problem was magically corrected.  Now it’s happening again.  Once again I checked all the settings and they are all correct but the problem persists. 


Note:  on the iPhone under Volume Limit there is a note that says:

“This limit does not affect phone calls or FaceTime calls, emergency calls and alerts, ringtones, alarms, system sounds, or Find My sounds.”


So no matter how I adjust the settings on my phone, it must be Bluetooth interfering and ignoring my settings.

Can you lower the volume of the external devices with the Volume buttons or the volume slider in Control Center?


Bluetooth is not ignoring your settings, your 3rd party devices have different built-in sensitivity and amplification factors, so their volume will not be the same as what you set for your internal iPhone speakers. iOS has no way of knowing the amplification levels of the devices you have connected.

You don't know that otherwise you would not be asking for help.

Borrow some proper Apple Bluetooth earphones and test your theory. You will find it only does it with the non apple stuff.

Now who's bug it that? Apple or Nothing's?

Thanks for your reply. Yes, I can change the volume with the volume buttons and through the control center.


I’m using Nothing Ear (open) ear buds. I can adjust the volume through them as well. I searched through their support site but found no information specially addressing this exact issue. Every site and posting reiterates the basics on adjusting the volume level on the iPhone and earbuds (of which I’m well aware).


The issue is why the volume for alarms and phone calls are significantly louder when Bluetooth is turned off compared to when it’s off and how can I change that. If anyone can help solve this, I’d be very grateful!

Yes, they are both Bluetooth. The issue isn’t related to the hardware of the headphones or speaker.


When Bluetooth is not enabled on my iPhone, the volume of alarms and calls is exactly how I set them.


However, as soon as I enable Bluetooth, the volume of alarms and calls increase dramatically, especially through the iPhone speaker, as well as through the Bluetooth earphones or external speaker.


The volume should not change from the original setting, but it does. But only when Bluetooth is enabled.

Are these Bluetooth headphones and a Bluetooth speaker? If they are, then they shouldn’t work at all with Bluetooth off.
