In my opinion it's an apple software issue. I have come to realize that once you update your phone it gets worse. Try restoring your phone to factory settings and don't update it or sync it to iTunes. For some reason the call quality isn't nearly as bad. Also, I know 3 people who have iphone 5's and none of them have the poor call quality. Coincidentally none of them have ever even synced there phones to iTunes or updated. Not sure if it will work for everyone but it has for me so far.

This is a good point. I sit right next to a DECT phone but, yesterday when an important call came in and I could not understand my caller (although he could hear me perfectly well) I went out into the garden, normally this can make some small difference, but yesterday it didn't. So I do not know where this leaves your theory?

An observation: I have never had the problem in the car on hands free. I assume it is because the car takes over the playback processing?

For me the enabeling of the "Hearing Aid" Setting brought kinda good results.

At least the noice cancellation seems to be gone now and i can understand my calling partner quite good.

hope that works for you guys as well.

go to: settings -> general -> accessibility -> hearing aid

try it

Well that's a solution which really works (if it isn't a AMR-WB Codec issue which is common for the carrier "3 Hutchison") but the volume is much too loud for me when hearing mode is enabled.

Its just my observation.

Turning off my DECT Phone close to

an iPhone 5 completely resolves

the problem!

Never had that problem with my iPhone 4

Any technicians out there?

Has anyone tried resetting to factory defaults to get rid of all updates?

relais12,

I invite you and others who say some measure completely resolves "the problem" to be more specific about which problem, and how you verfied that the problem was resolved. If you're referring to the drop-out problem, would you kindly perform the simple test I've detailed in an earlier post, and report if you can get your iPhone 5 to pass that test? I don't know of anyone who has been able to do that.

Adam,

I just switchd back to my iPhone 4S yesterday and since then, I have been making call after call and haven't had the issues I experienced with iPhone 5.

On a bad note, going backwards from using the 5 to a 4S makes me really mad because now I have an almost new iPhone 5 sitting in a box ;(

I don't believe there are 2 different versions of the iPhone 5 (carrier systems aside). And if someone is a 'reliable source' they would actually know what the problem is and know how to fix it. The hearing aid thing does nothing. Nothing. The Hertz test is a good test, but I get even worse reception when I call Verizon's own help line and listen to their recording. I even get mediocre reception when I call the Apple help line. Ironic. Just hope for a software or firmware fix. At this point that's about all I can do, since although Verizon claims they're looking into my case, I have little confidence that they will be able to solve it. I'm not sure Verizon even knows what it is. Good luck all.

What is a DECT phone? Is that the same as what AT&T call a microcel phone? If so, those are what is causing many of the problems from what I was told.AT&T stated that have several surrounding my location. Are these the same?

Going back to the 4S worked for me, too. Unfortunately the "deleted voicemail" files didn't transfer over on the iTunes backup. Oh well. Did you all see the iPhone 5 whiners skit last night on SNL? Haha. Puts our little problems in perspective. On the other hand none of the whiners were complaining that they couldn't use their phones as phones for work! But we are lucky we can afford this useless thing...and this is a lesson.

Dear SK1SK1

I can confirm I did the test today, I phoned the Hertz number and it worked fine on my iphone 5 and on my fixed line. One minute/call my iphone 5 is fine in another instant it is totally uncomprehendable, even in the same conversation the problem can come and go, that is what makes it so annoying. when it works fine I feel great, when it works badly (most often in an important business call) I want to throw it against the wall.

I am getting so upset about it - the only thing that is keeping me sane is the fact that other people are suffering alongside me.

I called the Apple help desk today, both the support people told me that their iphones worked great and how much they 'loved' them. That really made me feel better - not! They got me to re-install my phone from scratch and surprise, surprise - no difference!

They could not arrange a replacement because Apple support's it system was down today. 2.5 hours of my Sunday was wasted in fruitless effort.
