iPhone 6 Plus Bluetooth Volume Extremely Low

Ok I feel a little stupid... when I went back into my car I opened up the music on my phone and turned the slider up.. problem fixed... Thank goodness!! This didn't happen with my iphone 4 so I'll have to remember this. I think a lot of you have already tried this though so I hope you get a fix soon!!

I'm experiencing the same problem with my 2012 Toyota Yaris' Toyota Touch sound system. The problem is present since iOS 8 release, because before then the sound was fine and this problem doesn't exist. First with my iPhone 5S, now with my iPhone 6 and always with my iPad mini retina display. All them with the same issue. As it was said by dj3144the problem can be temporally fixed by killing Facebook app in background. It seems like a joke but it really works.

SAME ISSUE... iphone 6+, increased volume on phone and in iTunes, no background apps, does not solve the problem.... I will try with an Aux cord.... 😟

Good spot dude.....that worked for me......

I Get this problem with a pioneer stereo system in my car. Only temporary solutions I know are restarting your phone or sometimes if I open my mail app and I get new mail I get a alert sound and it usually goes back to normal (doesnt always work). I'll try using a alert sound a easier way next time this happens cause I don't get many emails. if it works i'll let everyone know.

It seems Apple knows about the problem and fixed it with an update. Make sure you are running iOS 8.4. Now I'm back to listening to my tunes at full volume. Yayyyy!

I encountered this for the first time tonight, after using a Bluetooth speaker for months with no issue. Using the Music app, volume (output, not slider setting) would drop drastically when advancing to the next song. Scrubbing/advancing further into the song would fix it, but the volume would drop again in following songs. I'm using an iPhone 6 on iOS 8.4.

I force-closed all apps and it fixed the problem. I had many apps in the background, including Facebook, Spotify, Overcast (podcast app,) and Twitch (streaming video app.) All have audio permissions, so I couldn't say which one(s) was the culprit. Give it a shot.

Having this problem here occasionally with my iPhone 6 connected through Bluetooth to car stereo and headphones. Wired connections are always fine.

As someone has already said, I'm pretty sure this is caused by the Facebook app (or similar) affecting the volume in the background.

As a quick fix, I've discovered that hitting fast-forward (hold down skip-forward button) then hitting play fixes the volume instantly. Also, in podcasts, hitting the skip-15-seconds button also works.

Disabling "Sound Check" in the Music settings also increases the volume significantly.

Hope that's useful to someone!

I am having the same issue with LG Tone bluetooth mostly but occasionally with the phone itself. I've found that if I hold down the home button as if I was going to use SIRI then shut it off it fixes the problem temporarily. I hope they come out with a fix for this soon. I shouldn't have to do that everytime I watch a video or listen to music.

I also had this issue with two devices. (iPhone 6+ and Marshall Stanmore Bluetooth speaker/Mercedes COMAND - sound normal for OS, and notifications, Music and Spotify super low volume)

The following actions did not resolve it:

A) Turning Bluetooth on and off.

B) Re-Pairing phone and speaker.

C) Closing and relaunching apps.

D) Power Cycling Speaker.

E) Updating phone.

F) Removing phone from authorized device list in car.

This Solution worked for me:

1) Under Settings>Bluetooth locate the name of the device [in my case STANMORE Speaker / MB Bluetooth]

2) Tap ℹ icon

3) Tap "Forget This Device"

4) Reauthorize and Re-pair

After these steps the volume issue was corrected for both the speaker and my car.

I'm on 8.4 with a 5S and I still have occassional Bluetooth music problems. When a notification comes in (email, sms whatever) it is back at full volume.

Then, when I pause my music, the bluetooth connection goes to sleep/low-energy level (I assume?) . If I than "wake" it, the volume is low.

I'm on 8.4.1 (updated yesterday) with iPhone 6 and pioneer car systeem. Having the same issues. Only when I receive a whatsapp message, the volume turns up with at least 50%.

I use Apple music and turned off sound check and my issue was fixed on my 2015 mustang gt 5.0 sync system.

Thanks for the advice. I just went into my phones bluetooth settings and deleted everything that has ever been paired with the phone. Instantly, the volume on my bluetooth headphones was restored. Brill, thaanks again.

Well, mine increased volume also, after deleting the full connection on the radio and on the iphone.... for 1 time... after that, volume was down to 50% again and again it increased if I receive a whatsapp or text messages. Very, very annoying!
