I put it on Verizon and Best Buy... Maybe that's why Best Buy is offering $50 off... Slower sales since the iPhone 5 is really an iPod in sheep's clothing.

Iphone 5 black 16 GB

I bought it about 25-30 days back.
the moment I bought it,10 minutes after that I got the first call drop ( I thought the person on the other side might have had network issues)

I then face call drops for more 2 times that night,a little woried about the problem,I thought i'd make more calls next morning and get to know the problem.The result was : 20-30 call drops in few hours.You know there is a problem when the call drops and it shows "Call Back" and "Cancel" when you touch Call Back,it wont do it !
for next 5-6 times it will keep on getting cancelled,then probably the 7th time you will be able to call back the person you were talking to ! this is a serious problem.

I gave it to the service centre,the software reset my phone and gave it back to me,however the problem stopped for few days,then returned again.
Now while talking I discovered a new problem !
The Choppy/Distorted/Robotic/Edgy voice quality of the person on the other side of the phone.
My voice is clear to that person but when he/she talks,its too bad .

Also,I noticed a very imporant thing.
** When someone is talking to me over the phone,and I am not saying anything or there is no wind around me that goes into the microphone of the iphone5, then I the voice of the person is CRISP CLEAR, BUT AS SOON AS I SPEAK,1 SECOND AFTER THAT THE VOICE OF THE OPPOSITE PERRSON CHOPS !
I TRIED AND TESTED THIS MULTIPLE TIMES AND ITS TRUE !

HENCE

1) EVERYTIME I SPEAK,THE OPPOSITE PERSON VOICE CHOPS/BREAKS FOR A SECOND.

2) IF IM IN THE CAR WITH THE WINDOWS OPEN AND THE WIND STRAIGHT GOING IN THE MICROPHONE,THE VOICE KEEPS BREAKING/CHOPPING.DISTORTING.

I WILL BE GOING TO THE APPLE STORE HERE IN MUMBAI,I JUST HOPE THEY DONT DO A SOFTWARE THING AGAIN AS IM SURE ITS NOT A SOFTWARE THING,EVEN A KID WOULD KNOW THAT !

PLEASE APPLE PAY SOME ATTENTION,YOU GUYS DO SUCH A GREAT JOB,A PROBLEM LIKE THIS SHOULDNT CREATE A PROBLEM MAN !

HOPE THAT HELPS

thanks !

UPDATE: Problem solved by switching to AT&T

After 2 Verizon phones, I decided to switch back to AT&T and have not encountered the problem since. AT&T told me that verizon's phone network is older and poorer quality (no shock ATT would say that about a rival), however, I have a new iPhone 5 and I'm experiencing the same call quality I had while I was on my old iPhone 4. Some folks have experienced the same problem on AT&T, but Verizon folks, I encourage you to give AT&T a try to see if it solves your problem. Unfortunately, I dont think the coverage is as good as Verizon, but call quality is my #1 priority with a phone. Good Luck!!!

Lots of people on AT&T are having this problem with the iPhone 5 as well. Glad yours works but I don't believe it's the network, and AT&T is not more advanced than Verizon. I dumped AT&T because they were awful. A nightmare.

I doubt this is the network (Verizon or AT&amp;T). I tested calls using a call over wifi app and still having the same digitized, robotic voice issue. This is most likely a software issue with the iphone. Apple, you better acknowledge this problem stat.

I'm also having same issues with poor voice quality. I just bought 3 iphone 5's and have same complaint on all. I'm on Verizon, having just switched from Android and T-mobile, I'm not happy at all with the voice quality. Have 4 bars on both ends of calls. At times it seems like the signal is overmodulated, thin, distorted, garbeled. etc. I've also noticed on several occassions that it sounds like my ears need to pop or as if I'm listening through a sea shell and has this hollow sound. The times when I notice it the worst are when there are other people in the background on the other callers phone. It makes it very difficult to hear what the caller is saying.

You hit the nail on the head. I also came from Androi T-Mobile and call quality was A+ and Verizon iPhone5 is basically an F because you cannot use the phone to make any calls where you're not missing half the conversation.

My dad has the same setup and he too has the same problem. Will check my girlfriend's iP5 tomorrow too. My guess is hers will have the same muffled (filtered) robotic (digitized, over-compression, distortion) qualities.

If Apple doesn't respond to these very serious complaints then they have lost all credibility with me (and I own an iMac, 2 iPads, a MBP, AppleTV, and that doesn't include what I use Apple-wise at work) and I will slowly begin the painful transition of moving all of my devices and media back over to Android. This is ridiculous.

I had the same problem as most of you when i got an iphone 5 2 wks ago from AT&T. I called them and they replaced the phone and everything worked fine. I suggest doing the same.

Oracle, don't know if you're just trying to help, and if so great, but I've seen this post on 3 different sites pushing AT&T. There are a ton of people on AT&T who are having the exact same problem. There are people all over the world having this problem on every network out there. The person who started the macforums thread was on AT&T. If AT&T is the answer then why are people on AT&T still having the same problem??? And switching means getting out of a contract which is easier said than done. I was on AT&T before and they were the worst cell company in history. Just sayin'.

No offense. But why was AT&amp;T the worst cell company? Apologize if not helping forum users.

Please create a new discussion thread if anyone wants to discuss anything other than the specific call fading or robotic voice symptoms on iphone5, and please focus on your personal firsthand experience with that exact problem, nothing else. My 3rd iphone5 still has the problem. Easy way to reproduce it is by making a test call to hertz on-demand 877-654-4400 and use headphones and keep the volume low. The first 10 seconds of the recording will be choppy and robotic. You can also reproduce it by directly having the phone on your ears and seting the volume in a lower range. If you call from a landline, it will be fine. I tested all the display phones in two Verizon stores using my iphone5 headphones and 4S headphones, and they had the same problem. The display models of iphone4S does not have the problem using my iphone5 headphones, so it is clear the problem is with the handset itself. I have not gone to an AT&T store to test their display phones, so I cannot comment on that. The Apple store does not have functional phones in their stores.

I had a friend complain about the same thing, with her new iphone 5.

She sent me the link to this forum question.

She came to my house today.

I peeled off the factory applied thick plastic film off the front screen,

Which was blocking the mic &amp; earhole cut out.

All good now!

Maybe, some (not all) people have the same simple problem?

Merry Christmas :-)

Some people already posted the same thing you did before. But watch out, get some forum users get all "bent out of shape" stating the obvious. Also, let me clarify to people having problems with iPhone 5, I know not being much help, hope to get problems solved!😉

Beside this ridiculous post about the plastic film i now tried a Galaxy S3.

I had to flash carrier branded ROM to make sure HD-Voice is enabled and what should i say ... Voice quality is awesome.

So i think there are 2 main issues with voice quality here:

First issue:

- HD-Voice (AMR-WB) incorrect settings. Maybe to due no test devices from Apple for carrieres so they weren't able to provide correct ipcc profiles. Both Apple and the carriers are to blame. Because not every carrier with HD-Voice enabled suffers from muffled (and sound like sand on the speaker) voice quality on the caller side (my hearing the other person muffled .... set in any voice quality issue here, except bumping volume).

If you suffer from this problem you may also suffer from massive battery drain during standby.

- Bumping volume. This is clearly a thing for an audio engineer as there's a treshold wrong. I called a Sony xPera S two times - with iPhone 5 and Galaxy S3. The latter offered superb voice quality.With the iPhone 5 i had troubles understanding the person whom i was talking with. It sounded like the software wanted to overcompensate something and offering absolute silence so only the voice of the other person is present. Though if the voice is speaking quiet or changes a lot during a call (like from talking in normal to whispering) the effect is so clear that it could be recorded by just holding a mic to the speaker of the iPhone (that one to your ear not that one on the bottom). All in all you get the impression like there' stuttering/lag. That's the software trying to filter out ambient noise on the other side. Don't ask why your iPhone is doing that. Normally the other phone is supposed to cancel out ambient noise.

Another annoying thing to me is that noises containing fizzling like when speaking an "s" the iPhone often playback such things very loud or louder than the normal conversation. That's annoying and Galaxy S3 doesn't do that.

So for now i consider keeping the S3 and wait for the next iPhone to be released. I really have to make phone calls and can't afford an € 789,- iPod Touch with the ability to make poor phone calls 😟

Oh and i already told you that apple refused to change my phone again (every single phone had scratches). Luckily returning the phone was possible (but no exchange). I changed the phone 3 times.
