Iphone X weak signals

I received my iphoneX yesterday and set it up with my previous cellular network. Since then i have noticed that signals strength is significantly weaker than before both at home and on the go. Call kept disconnecting while travelling. Never had any sumch problem on iphone 7 ios 11.1 and 11.2beta. I have tried ringing apple care and they have asked me to reset network settings which i have done but issue is still there. My old iphone 7 at same network and same ios is in my other hand showing full signal strength. Is it an issue with iphoneX signal antenna?

So the issue is that the A1909 model has a modem in the ATT version of the phone that causes a significant signal drop on LTE. ATT only has this model. Verizon has the A1865 Model which is much better.


Apple will continue to Ignore this issue and give you the run around because there is no fix short of returning the phones and starting over. I have spoken with 3 Apple senior managers who have each sent me a new A1909 model, all with the same issues. They all took me through the 10 steps on their site including connecting me with ATT to check outages and low signal (in Chicago - Right!).


If you are stuck with an ATT phone the only way to boost signal is to go into settings and cellular and turn off LTE. You will notice signal strength immediately comes right back up to 4Bars. You will still have 4G just not LTE so will be a bit slower. If you can transfer to Verizon you will get the A1865 Model keep your number and the problem goes away.


Good Luck

I have sent 2 back and on my third and all the A1901 models have this week signal problem. My friend also has it. I have them side by side with my 6S and the X has reliably half the reception. I am told the model A1865 does not have it but I have been unable to get ATT to send me one of those.


I have done the full trouble shooting with two Apple Chat people and 2 on the phone people - 4X total

All steps on the document on their website INCLUDING going back to ATT and getting Pinged, New Sim Card, Verifying no outages or tower maintenance in our area.


Apple clearly knows this is a problem and disappointingly to a customer that had their first Mac computer in 1986, letting the customers get screwed. Looks like I will finally Jump to Galaxy unless they make this right. I do not need to be treated this way for $1000

I now own both the A1901 and the A1865 models.


There is no doubt at all about the A1901's failings - I've had plenty of trouble in areas that I've known for many years to allow reliable cell phone use. My iPhones 4, 6 Plus, and 6s Plus *never* had trouble in many areas that the iPhone X has been failing.


I have more recently had dropped calls and other issues with the A1865 model too, but have so far only used it in an area of Florida (Naples - Tampa) where I haven't previously used a cell phone much. I therefore can't claim on experience that it's just as bad as the A1901 model, but I suspect that it is. T-Mobile's service map shows that it has strong coverage in this area, and it would be surprising if it didn't. My brother bought an iPhone X A1865 - he's an extremely heavy user in areas all over the U.S. and Canada - and says he will be returning it after a month of troubles using its cell phone.


So the problem with the iPhone X seems not to be related to the different Intel / Qualcomm modems used in the different models. Nor is it related to any failing by cell system providers. It's something else in the Apple phone, and it's long past time for Apple to acknowledge it and redress it before it permanently damages its relationship with business-owner customers like me who have contributed significantly to its success.

Indeed that’s what I have been saying in these posts from the beginning. It’s not network settings, SIM card, internal modems, OS. I am certainly not an electrical engineer but I would think if the phone signal strength for cellular and WiFi is inadequate in known high strength areas then it’s the **** receiving antenna in the device and good luck getting that acknowledged or fixed in devices already out there

A question: remember years ago when there was a stink in the press about a new iteration of iOS showing a bar fewer and seemingly having poorer reception?

I bet you don't remember Apple's solution; change the settings for the bars, so for the same signal strength it would show an additional bar. And for most people that "fixed" the problem, because their phones now showed the same number of bars as their friends. The poorer reception was entirely subjective.


Bars are a terrible way to show signal strength, as there is no standard in the industry for what signal strength a bar represents. Every phone model is different. There is a way to put the phone into diagnostic mode and read the actual signal strength in dBm. that is the only way to actually compare phones.

I’m on my second iPhone X. First had a defective modem and caused a complete drop of cellular service when on LTE. Second phone seems to handle LTE properly but the signal strength is atrocious. Most of the time I am stuck on 3G and when I do get LTE, I usually have no more than 2 bars, max 3. I experience LTE dropouts that do no fail over gracefully and missed VoLTE calls. Nothing except locking the phone to 3G service only fixes the problems. Extremely disappointed in this and nearing the end of my patience. I’ve spent a week troubleshooting this phone. I expect better, much better for $1,500. My wife has no problems with her iPhone 8 Plus, and I also have no issues with my old iPhone 6s Plus. Same goes for my Galaxy S8+ and BlackBery KeyOne Black Edition. Everything but the iPhone X works flawlessly in fact.

Please let us know if you figure out a way for Canadians to purchase the A1865 version of the iPhone X.


I had my iPhone X replaced today, in a Canadian Apple store so I got another A1901 model. Just got it set up moments ago - will report here if the problems persist - but thought I'd report a couple of things Apple staff told me.


1. Apple has a "threshold" of 20% on dropped calls. If the iPhone is dropping less than 20% of your calls it's considered within tolerance!! Their analysis showed that my phone had dropped four of thirty calls so it was not considered actionable. Their analysis did not show that the phone had failed at least ten times to MAKE calls in areas where my iPhone 6s Plus worked for nearly two years.


2. Apple proposed that I set the device to use 3G instead of LTE protocols. I declined, believing that after paying $2K for the latest iPhone I should not have to roll back to older and slower cell protocols to use it.


After discussion they did propose replacing the phone, which has just been done. Fingers crossed.

I have had my iPhone X since December. It is the A1901 model. Four calls to Apple Support that it just doesn't search and connect to cell signal while driving. I have to repeatedly pull over and cycle through airplane mode to get it to connect in areas that never had a problem with my 6S and other prior models. Have restored as advised by Apple from iTunes with hard drive backup, restored again from iCloud backup, replaced SIM card at AT&T. All efforts did not help. Will demand a replacement.

The bad news is that a replacement probably won't resolve the problem. I've had an A1901 model go through all the trial balloons suggested by Apple techs, and then be replaced completely, with no improvement. I've had an A1865 model completely erased and restored by an Apple tech, replaced the SIM at his suggestion, and switched to a different case at his suggestion.


None of these changes have resolved the problem... I've got two iPhone Xs that I cannot rely upon, and have started keeping my old 6s with me for times when the iPhone X is failing. (The 6s has always worked reliably, and still does.)


Reading back you'll find that lots of others have also been through the try-this, try-that, replace-the-phone experience without getting a reliable cell phone. Something in the iPhone X has been overlooked by Apple, and a lot of us are waiting for news that they've figured it out and will be redressing the problem for customers like us.

After upgrading to the X from a 6s, I immediately noticed the weaker signal. Exchanged the Intel model for the Qualcomm model, but no difference. If people are saying the 8 has the same issue, it must be something to do with the glass back / antenna... definitely a hardware issue. Hoping they come out with an SE2 so I can sell this overpriced POS. Love the X, but if it can’t do a good job at it’s primary function it’s not worth it.
