Time, because it rules EVERYTHING!
I know you asked for people using O2 signal, but I still thought I'd reply bc UK:
I am with Voxi (Vodafone's signal) and I've noticed I no longer have 4 bars of 4G when at home (I did on my iPhone X). It hovers at 2 bars now, occasionally dropping to even just 1 bar. When out in the City Centre, I get 4 bars of 4G, but nothing loads (never had this problem on my iPhone X in the same places I'm noticing this!)

Hmmm that’s not good! Thanks. I was wondering it’s the different bands we use in the U.K. to the US if it would affect us. What’s the WiFi like on your phone?

Apple should install more towers for the carriers, put that trillion to good use. :D

I'm giving my Xs Max a week trial, using it as my work phone. If I drop calls or data doesn't work where it used to, I'll just send it back.

rsrp0 should be between -45 and - 140dBm
My rsrp0 is -108
rsrq0 -18
rsrp1 -114
rsrq1 -25
Band 2 currently though i'm often on band 12 at this same location.

I'm in a building. Values are similar to my 8+ with AT&T. Current phone is a Max on T-mobile.

My speeds are 20mbps down and 1mbps up at this location. This is about double my 8+ AT&T.

Curious what others think. Just tested this at home:

X was -66.5

XS Max was -105

Both in the same vicinity. Attached screen shots of the data. Would you return this? My concern is the vast difference between the X and X Max.

After seeing some further readings from you folks I won’t even open the box on my max tomorrow. It’s going straight back to Apple. If they can fix I’ll reconsider down the road.

It looks like. Your numbers are where the good numbers should be.

I tested on both X and XS Max and it's the exact same poor reception -105 rsrp0
So your phone isn't worse. It's same. That's good :)

Going to add to this... I am not getting any reception on my Xs Max where I’ve gotten reception before using an SE and few androids. On Verizon

True but from the comments I see it's really bad and I get battery drains in stand by and I'm afraid it's the cell reception.

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.

Thanks appreciate it. I guess I wasn’t overly focused on the numbers, per say. I was surprised at the difference. Someone else mentioned could be on a different band....

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!

Excellent idea. However, I need to first work with support to uncancel my cancel abs trade in....

I think I’ll keep it

Thank you for taking the time to do this, but I'm not spending my time beta testing for Apple.

The Speedtests and testing I'm doing is to figure out how reception compares to my old iPhone and if I'm keeping the new one.

Not playing the lottery on a $1250 phone when mine works just fine.

Don't you have an option to return it? Assuming you do, how is it playing the lottery when it's 100% likely that you'll get a refund if you're not happy? Open the box. They already have your money so you may as well see what you have.

I would still try it out. Its from apple and there is no restock fee. You may get lucky and it works out for you. If the phone was from a carrier then I would not take the chance cause they do charge you a restock fee.

This is pure gold!

Don’t believe the fake news....

Good lord.

I have zero issues. I’m on Verizon and not in a good area for cell service.

My 7 plus got one bar at home. My max gets 3 or 4!
Still spouting this "fake news" BS? Hahaha. Bars mean absolutely nothing. Actual signal values and comparisons between phones while on the same cell site, cell sector, and LTE band prove it is performing slightly worse than most phones.

Your logic is like saying, "there isn't an drought in California! It rained 3 inches today where I live!"

If this isn't an issue you are dealing with then why are you constantly in this topic? Move on with your life.
