How can I fix the low volume issue on my iPhone 15 Pro connected to Bluetooth stereo?

Go to Settings > Music > Sound Check and turn it off

Hey there Japoole76,

While there may be a setting on your Bluetooth speakers that'll allow you to have higher volume(such as setting it to something else that isn't 'late night'), we'd like to help by ruling out some basics. We also want to learn more about what's happening:

1. As the Bluetooth speaker still sounds loud when paired with other devices, we wanted to ask if you were able to test a different Bluetooth accessory with your iPhone, like a pair of Bluetooth headphones?
2. We see you have iOS 17 installed, but the latest version is iOS 17.0.2. You can verify this within Settings > General > About. In case you needed it, this link shows how to first back up, then update: Update your iPhone or iPad
3. Any issues playing sound from the built-in speaker on your iPhone?

Cheers!

I have the same issue iOS 17.1

Did this it definitely helped there still feels like something is missing your tip really helped though thanks!

I found the solution!

1. Swipe up from the bottom of your screen to bring up the Control Center.

2. For volume, drag the slider down to the bottom, then back up to max. This should reset your volume settings for Bluetooth.

Playing with the slider really helps!

This must be a bug

Had the same problem, just restar the iPhone by the troubleshooting mode. (Volume up + Volume Down + Long press on the lock button until screen goes black and then the apple logo appears, dont do the slide to turn off)

i had same low, or lower, volume issues with Bluetooth connected speakers. After reading all the posted responses, I sorta combined them and played around. This is what worked for me. I searched “control center” on iPhone, then tapped on “customize settings” (or something similar, but it was the only one of the 3 options with “customize”. Then the ear icon w/ heading saying “Background Sounds”, under that was a slider for “Volume with media”, I slid it to max, obviously, lol. I connected with my Marshall Bluetooth speaker and it was fixed, much louder. Hope this helps.

Hey, try going into settings and then into music…make sure sound check is turned off. Hope this helps!

I’m experiencing the same issue 17.0.2 through 17.1. Bluetooth audio is lower than previous iPhone and iOS 16
