iphone 6 cellular reception

Well, I had a surprise today - Mobiles.co.uk said they couldn't do a "doorstep swap" for my faulty phone, but they DID! So I have my new phone up and running already! So far, and it's been on for a few hours now, the signal IS consistently better. It's not the best, but it seems more consistent with what I'm used to. I'm on 3 bars or 2 instead of the 1 bar I was getting with the "old" phone. So maybe it's a batch issue. Mine is 64gb Gold on O2, if that helps anyone.

Both my wife and I both purchased iPhone 6's (hers gold, mine space gray purchased 1 week apart), and we are both coming from iPhone 5's and both still on AT&T here in the US.

Both of us are experiencing the same issue as the OP, in that places (like our home, and the commute path we take) where our iPhone 5's would have signal, our iPhone 6's both show significantly less reception.

In our home, where we have never had a problem with reception before, we both have rooms now where we can't make any calls due to no service. After testing the reception in a few areas I am used to looking at my phone, I would guess a minimum of 1-2 bars (or dots) reception less on the iPhone 6 than the 5.

Right now, as I write this from work, I was used to 5 bars consistently on my iPhone 5, I am only receiving 3 bars.

My iPhone 6 started doing the no service thing. I called At&t and got no where. I went to the Apple Store and they replaced my phone and gave me a new SIM card. It has not shown no service since. Very happy I went and got a replacement instead of trying to live with it.

There have been posts where people having reception issues, had their SIM cards changed....which solved their problems. Looks like with some it's the network, some the phone and some the SIM card.

Update...

After 24 hours I can honestly say that this "new" Iphone 6 is only a little better than the other one, if that. It's still on IOS 8, so not updated it. It's a bit dodgy for wifi too. So to compare - 4s, 5s and this phone in the house - the two older models get consistently 3 bars - this new phone ranges from 1 to 3, but mostly 2 in our house. So it is still less but not as bad as the always 1 bar that I got with the earlier Iphone 6. However, took my husband's Iphone 4s and my phone into town today (both same network, just in case you were wondering) and tried to get the free wifi from the coffee shop. The 4s found it straight away (strong network) along with a few other less strong networks nearby. My Iphone 6 kept showing a message of zero networks and then said could not scan for wireless networks. Left it for 5 minutes then tried again and it finally found them, but not as many as the 4s found. So it seems there's a delay in finding the networks (which would or could link to how quickly it can or can find and switch from a poor 3G to a good gprs signal). So it's back to switching/finding issues. Really rubbish from Apple. Thinking of cancelling my upgrade and going to an LGG3 !!

Can you try updating it to 8.0.2? As I wrote earlier in this thread, that fixed my periodic No Signal problems. Haven't had any problems since updating.

I updated the 5s to IOS 8.0.2 but that just screwed up my wifi all together - my router now (after never any problems before ) started losing signal immediately after the update and connecting the 5s to the router. I keep having to reboot it every hour or so as it just drops out. So, I'm not updating my shiny new 6 just yet...

Experiencing poor cellular connection (few bars, delayed voice when answering) here on our 4G provider in Taiwan. Similar to everyone else my previous iphone 4S had not such problems. This same problem is occurring in both my wife and my new iPhone 6. Apple how could you get this so wrong? Is there a special way you want us to hold this new phone?

Same thing here, tmobile usa. Got my iPhone 5 full signal iphone 6 next to it missing bars. Called apple today the representatives on the phone was a joke telling me " honestly I really don't know what to tell you" (thank you, just what I wanted to hear) when I said I would like to return it he said " I feel like your not complete with your order.. You probably wanted to check the phone" really sherlock?! Thats why I paid $700 and waited a week, to check your phone? . after 55min and 3 representatives this phone is going back to Apple. Crazy disappointment. their customer service got really bad

I have opened radar 18552410 for a reproducible version of this problem if anyone at Apple reads this that I am happy to help troubleshoot.

ive sent feedback to apple re these issues...I still have problems..

Call apple !!! support ! You need to restore ! didnt work, well you should restore . !!!

Dropping everything ? Support Did you Restore, if you have restored than you should try to restore !

so call support ! they say restore ... if that doesnt work call support ! they say restore , ask if others have problems ! they denied any known issues, but you should restore !

How's your day ? great I.m a lab monkey to apple support, I just restore my iphone 6 plus 128 g everyday now... I get up and Restore ! have problems ! I think Ill call support and they will have me restore ....

DID I Mention ! Restore doesnt work ? yes, please try restore !

im confirming this with iphone 6 plus from the U.S. using Globe or Smart sim. All our 4 iPhone 5's have cellular signal except the iPhone 6 plus. Updated with the latest iOS 8.02.

Same issue here... Iphone 6 keeps dropping my wifi (its already on WPA2), dropping my LTE, and has rather poor reception in comparison to my IP4 and 5. What i'd like to know is what Apple plans to do about this. As it seems, almost everyone that has an iPhone 6; have the same issues with wifi and poor reception. That sounds to me like a hardware issue, I happen to be on the Sprint network, but these issues are across all carriers so I know its not just Sprint. I'm going to visit my local Sprint store, and if we cant come to an agreement I think I'm going to switch to Samsung..

Did you ever get this resolved? I'm having the same issue.

I have this issue also. I have an IPhone 6 Plus 64GB on the AT&T network.

I've performed a hard reset, reset network settings, and turned on and off Airplane mode. I'm running 8.1.1

I have a fairly consistent "No Service" message and other times low signal strength. Callers are going straight to voicemail and other times getting through.
