Q: iPhone 6 Plus Volume

I faced same problem, took it to shop and they blindly said to replace speaker. But after a long googling, I scrapped a pin across the speaker mesh and cleaned with alcohol using ear buds .

Phone works great now, volume is loud and clear! This may due to sweat or spilled liquid which is blocking the small spores of the mesh . Please don't try direct pressurized air to the earpiece speaker which will damage diaphragm . Its very delicate .  Also when u scrap with a pin , please don't apply pressure at all. Just scrap lightly and you will be able to see such a lot of dirt coming out from that small hole.  Hope this will solve your problem .

YES! This did it. Q-Tip + Alcohol.

I had mine for a year working correctly and one day the volume dropped almost to nothing.  I tried someone's solution of the hearing aid setting and it helped a little, but noticed the greyed out Noise Cancellation toggle, so followed your advice and turned it back off.  When I toggled the Noise Cancellation on, the volume was up louder than with the hearing aid setting.

I don't think it's the NC being on, I think there's just a bug in the software so turning everything off then back on fixes it (at least somewhat).  They said now they are recommending a factory reset and/or loading the newest software version.  In other words they have no idea why their phone with 75 different functions can't do the only one that is absolutely crucial.  This will definitely be my last iPhone.  The camera is MUCH worse than I was led to believe, it has lots of bugs (the auto-brightness feature never works), and there's nothing it does that sets itself apart from other smart phones.

Gruffalo62, Thank you. I removed mine aand the volume is fine now  

give the speaker holes a good clean with alcohol or aftershave it will work 100% sure

Oh my gosh, this former valedictorian is thanking you right now. I feel so dumb. I have been doing the same thing (leaving the plastic on until I get screen protectors) and could not figure out why the sound was so quiet when I tried to talk on the phone holding the receiver to my ear. I had turned the volume up all the way and put the few calls I've made on it on speaker just to hear. I was trying to find something in settings. Nothing worked until I googled this. I cannot believe I didn't figure that out before I saw your post from 2014. LOL Thanks!

I Had this same issue. Is it in a case? I bought a case from the Verizon store and it blocked my volum. Try taking off the case and see if that helps.

You're the best! This actually seems to work - everything else proposed here didn't for me. Raising the volume with the side volume buttons DURING a call definitely made a difference. Thanks!

QTip + alcohol (or aftershave) on one tip and leave the other side dry.

SWipe with the wet side then dry side to clean the gunk. (Repeat the process 4-5 times)

IT's not really visible, but once I did it, sound increased dramatically.

Worth a shot.

Mine is out of warranty and the price they are asking to replace is AED 400, if it is a common issue with lot of users, then it is supposed to be the manufacturing defect in Iphone 6 and the company should replace it for free.

No, it's not a common issue. If you read through this thread, you'll find that a number of people had dirt in their speakers or left the plastic on.

Don't be embarrassed. I drove all the way to the Apple Store, watched the genius scrub the heck out of the earpiece opening and shook my head when the volume returned to perfection.

This happened to me suddenly after owning the phone for quite some time. Hearing aid suggestion didn't work for me. I placed my mouth over the ear slit of the phone to suck then blow. I know it sounds (and probably looks) ridiculous, but it worked instantly. Hope this helps anyone else with the same issue.

I Had this problem and it got progressively worse

i work in the cleaning industry and my phone is constantly subjected to muck and bust

this may sound crazy but if you get the smallest screwdriver and push it into the speaker holes you may find them to be blocked and stopping the sound from escaping as it should.

it worked for me so I reckon many people will have the same problem as the holes aren't protected from anything.

good luck and I hope this helps people.

  That did it!
