iPhone 7 Plus Phone Call Sound Quality

Battery issue on the other models is a brand new one having to do with iOS 10. It was shutting off people's phones at 30% (opposed to 1%) and they'd plug into charger and it would say 60% then unplug and immediately says 30% and shuts down. Also battery drain happening a lot faster.

I haven't had this issue as I upgraded from 6 to 7+ before upgrading the 6 iOS.

But as you can see these call issues are pretty bad. Again I couldn't even call 911 from my house if I needed to right now because I only have a mobile phone and it's not working as a phone!

I'm honestly questioning just asking Verizon to swap my phone to the Google Pixel. It's supposed to have the best camera anyway. And that's saying something since I've never had an Android and I'm a huge Apple fan (and web designer where our whole industry is Apple is the standard). I haven't gone back to Windows computers or non-Apple phones for like 10 years!

I guess I could try to swap for the iPhone 6S+ too but that just seems like a downgrade. Plus I know two people who have working 7+ on Verizon. I just wish they'd figure out how to tell which ones work by serial number so they could guarantee me a working one on phone #3.

Ditto! Same problem with my iPhone 7.

Try speaking loudly directly into the bottom of the phone. Treat it like a walkie talkie. It's the only way it works for me. My iPhone 6 can be used as a normal phone

I'm pleased to report the "Setup as new iPhone" has improved quality on calls for me. Please see my YouTube video for the before and after results that I have had with my phone. The phone has not changed so it's clearly a problem that can be solved with a software fix.

Hi Andrew- setting up as new did not work to improve outgoing phone quality with two devices previously. Is there something new that may fix the problem now?

How did you get to the "Set up as new" - Erase all content and settings, Restore using the Restore button in iTunes, or DFU restore? Each produces slightly different results.

Though I've done it before under guidance from Apple Support I fully reset my 7+, before doing so I completed backups to my computer and icloud. I set my phone up in a quite room, during this process I chose to ignore the two part verification. Once set up was complete I phoned my answering machine and left a message, I compared the clarity of this message with a message I left before the reset and heard no real difference. I also set up a personal greeting using my phone before and after the reset when I compared them there was again little difference. Next I restored from the backup on my computer and repeated the exercise and still little difference. In my case setting up as a new phone doesn't seem to have improved my voice quality during calls. I've tried my phone at different distances from my face and at an angle so my mouth was lined up with the side the mic is located with no discernible difference in quality. That's two 7+ I've owned both of which exhibited the same poor call quality and neither improved after being set up as a new phone. I'm still wondering if it's something to do with the Phone App as voice quality is fine in other Apps like Voice Memo and Facetime, the common entity is the Phone App. I've looked for other Phone Apps but can't seem to find one and it seems as though Phone App is one of the few Apple Apps that can't be removed.

Lawrence, following my email to Tim Cook I was called back by someone who was clearly not part of the normal support channel. I was specifically instructed to "Erase all content and settings" (which logs you out of iCloud, Find my Phone etc..) followed by "Setup as new iPhone" and specifically to avoid any sort of iCloud or iTunes restore. Please see my You Tude video showing the call quality before and after this process, I'm sure you will notice a difference. If anyone else is doing this please remember to turn off 2FA on your account first, otherwise you are sent a SMS verification code, but by this point your phone is half-reset and cannot receive SMS messages.

It's a real pain having to download all my apps and set them up again, but at least I can use the thing to make a phone call without having to plug the headphones in.

Have you tried with Skype and Facetime?

As setting up as New fixed it for Andrew but not for you, my bet is that there is more than one problem with similar symptoms.

That's a great idea. That would fix it

Haven't tried Skype but Facetime works fine even with me being over a meter away from my 7+ during the call. There only seems to be one common entity and that making calls using the Phone App. Could it be an issue with Phone App, some 6/6S owners have reported losing call quality when they upgraded to IOS 10.....

I spoke to my AT&T sales person who also has a 7. He is convinced it is a conflict with the cell providers and them upgrading to digital. He told me turn on wifi calling when home. Which I have done. Not sure it has made a difference but don't know if I am still going over the cell service provider or not.

That's a good lead. It could be the phone app, but it could also be the carrier settings download.

There have been cases of a similar issue where the customer installed the case before removing the final layer of cellophane wrap. Are you certain that all of the cellophane has been removed?

Would a carrier issue reflect on the two Android phones I've tried my sim card in when both phones made clear calls.
