I would not try to compare the indicated rsrp values on the different modems in those different phones. There are no technical documents available that show the derivation and scaling of those values. Ignore them and use 1) whether you have a signal or not and if it is consistent, and 2) if you do have a signal use speed tests to compare the quality of the connection.

The field test menu on different phones can be useful to ensure you are on the same tower and band, but I would caution comparing any of the signal quality information across phone models.
But we know numbers that are showing good signal on the max. So we should still look at numbers are

In that case, rsrp0 is -112 for me while rsrq0 is -28 and I'm hanging out around 2 bars.. only seen the network drop once all day at work though...

My speed test is abysmal... 3.29 mb down, about the same up. Not sure how this compares to my previous phone...


My numbers are almost exactly as yours on my newly activated iPhone Xs Max with the rsrp0 and the rsrq0 numbers. I ran speed tests on my wifi and it's 130+mbps in house and about 3.5 to 5 mbps down and up (what my carrier delivers based on my current plan). These are very similar numbers that I ran today on my 8 plus, as I did a pretty complete battery of tests on that phone before flipping that number over to the Max this afternoon.

I ended up just letting the cell company set it up and if there's tech support I can simply say "I did it their way" and not end up looking like an unqualified doc. I'm a bit of tech dumb with some of the "manual" suggestions here (DFU/restorations and such I think I'll leave alone until I know more of what I'm doing). So far, OK, although I will say that the "fidelity" of the voice call on the 8 Plus was better/"richer" in tone, it's still better than other phones I've used in that regard and seemed to hold the six test calls so far.

I'm in a weaker coverage area in many situations and the basic tests done so far give no alarm bells, anyway....with exception to not seeing text messages transfer over I have photos, address book, apps installed, face ID working well, so if I could figure out how to bring back the message texts (or maybe it will just show up through the wifi backup later) I'm off to a good start.


The iPhone "combine" continues......we'll see how long it lasts. No complaints so far amongst the 25 Xs and Max buyers over the last 5 days in the field (it's U. S. Cellular) according to my sales guy, and he's an Apple guy so he is pretty in touch. He is concerned about the Intel modem switchover (as USC has used Qualcomm previously and he well knows the drill here) but so far isn't getting wind of what we have seen so far here. If they are it's going to call support and not so much back through the store.

So many people worried about what I’m going to do with my phone, didn’t know you all cared so much.

You guys seem to be spending a lot of time and energy focus on how many bars you have and speedtest. While helpful to see if you are experiencing major performance degradation you should really be focusing your energy on working with AppleCare support. This is what I am doing.

The best way to solve the problem is to work with AppleCare to get the baseband profile installed which enables debug logging for cellular.
https://developer.apple.com/bug-reporting/profiles-and-logs/

Then you will need to repro the issue and create a sysdiagnose which compresses a bunch of logs together. Then get these files over to support who then send the files to engineering. It is only then that engineering can finally take a look at the hard data and dig through 1000s of lines of logs to try and figure out what is the root cause.

Then after root cause is found then they can work on writing and testing a code fix.

Spend less time doing speed tests and more time working with AppleCare to gather logs to send to Engineering!
Interesting that they didn’t offer this option to troubleshoot further with logs to me today.

So, I finally received mine, and unscientific as this may be, it seems that this one is not afflicted by the issues mentioned ITT. Believe you me, I had the return page ready and waiting. But upon popping in my spare Verizon SIM and connecting the XS to the 5GHz WiFi, I am not noticing any difference in signal strength, nor speeds betweeen the iPhone 7 and the XS.

That said, I am not about to go through and look for issues. I can’t see any, and that’s good enough for me.

What an utterly gorgeous phone by the way!

We see these sorts of so-called issues after every launch. I still remember when people were literally comparing the blue tints of their phones.

Apple is not known to run their wireless chips at full throttle like other handset manufacturers. Running a chipset at full speed to score a high mark in the one speedtest that android actually wins LTE/WIFI, is clearly not their priority.

I'd like them to lead this space as much as the next person but most people probably wouldn't notice this difference.

You hit the nail on the head.

I've worked in tech for well over 25+ years and most people would not know the difference between their wifi, let alone which band they're using. The vast majority of WIFI setups require that you set either 2.4G or 5G and again, most people would have probably been on 2.4G. 5GHz does not have anywhere near the coverage of 2.4GHz and the power output is also extremely limited, especially in the lower range.

Oh, I am :) I WILL look for issues because it's my only chance to get money back if a no-go. I'm usually the guy who waits a few months then gets the skinny on the phones in practice, but I really need another phone so I ordered up. I waited wayyyy too long on a limping phone to get a chance to buy this one - the phone I have wanted Apple to build for a number of years now.

That said, I agree with everything else you said - some will some won't have issues, but it is ONE BEEEEEAAUUUUUUITFUL device. It certainly is sexxxxehhh....

It is not until you get assigned to a Sr Applecare rep and they start interacting with engineering that they start requesting debug logs. I have been through the drill several times over the years and it is the same steps where you need to install a debug profile for the issue you are experiencing.

Then after you repro the issue you gather logs and send it to Apple and then you wait a while. Hopefully since this seems to be a trending issue it will get fixed in the next month.

Which is exactly why the people who are knowledgeable should hold manufacturers accountable by making issues well known. Everyone benefits from the solutions and better products in the future, including the people who have no clue.

This issue is well known to Apple. The antenna reception was piss poor in the FCC Certification. Anyone can find it. Most won’t.

It’s a poor antenna design. Most likely not an error, but a known pre production calculation.

You can't say that with certainty. They could have kept the same as the x. I'm sure they tests all this etuff

1500 phone - no excuse to save $5 on their dispute w/ Qualcom. the phone should be PERFECT.

The antenna has been completely redesigned from the X. The breaks are different. I assume, it was done to implement 4x4 MIMO support, as the X chassis was only capable of 2x2.

I’m not sure if my phone has a problem or not. I was at school picking up the kids. While waiting in the car I texted my husband. The signal was so weak, there was a lag sending them. I was only typing regular texts but they uploaded as slowly as if I were sending a photo. This has never happened to me there on my 8 Plus before.

Could this be caused by that reported antenna issue? I know there’s many things that could cause what I saw but I wonder if that potentially is what a poor antenna design could cause.

Would the XR be likely to be worse? I love my Max, but I do need reliable cell service. I’m going to have to pay attention.

I had no problem with WiFi connectivity on my Max and wouldn’t have paid attention without seeing these threads. I did notice my radio steaming would cut out 2 times on my daily walk the last few days where I never had an issue with my Plus. So when I really started paying attention and comparing, I realized how poor my cellular connectivity was. I’m glad I pulled the plug before the return deadline. I’ll get back in for a new phone once Apple fixes this problem.

I only just finished reading page 11 of 36, so I'm going to post this now and finish reading afterwards.

I still have my 256GB iPhone X (unlocked SIM free with qualcomm chipset), and up on Cheyenne Mountain by NORAD we have poor AT&T cell service (most cell services here are poor, go figure with all those antennae on the mountain). I usually have to turn off LTE and use 4G service when I'm out for a walk, and usually need AT&T Wi-Fi calling for best performance at home.

Both have Carrier version 33.2 (modem firmware is different, Xs Max 1.00.07 and X 3.00.00) and iOS 12.0

So far my Xs Max is outperforming my iPhone X. They both have the same signal strengths with either 1 bar of LTE or 3 bars of 4G. I have not dropped any calls with LTE turned on, as opposed to my X that dropped them on LTE often.

4G internet speed down/up
------------------------------
Xs Max speed mbps 4.64 / 0.66
X speed mbps 1.13 / 0.61

LTE internet speed down/up
------------------------------
Xs Max speed mbps 0.43 / 3.66
X speed mbps 0.58 / 0.93
