    I am curious to see if there is any pattern to the phones that have problems and those that don't. Please post the phone type you have, Xs or Xs Max, storage option, color, and who/where you purchased it from. And based on the chart please indicate the factory and date of your phones build. And obviously indicate if your phone is fine or if you have problems with data/signal/wifi.

    Thank you

    Apple upgrade program opening day arrival

    I found 5 ghz weak and not workable outside of house, ok inside
    The 12.01 upgrade fixes this problem
    LTE works like normal although it seems a bit better (I live in weak signal area)

    9TH week 8/26-9/1
    LTE fine, same as my other iPhones

    Clarifications:

    LTE - Decent service and performance vs our Qualcomm iPhone X and 7 on AT&T, and much better than our iPhone 6 on Ting.com Mobile. Our Cheyenne Mountain neighborhood has notoriously poor cell service on LTE, and we get 1 bar with AT&T or Ting (I think it's an MVNO on T-Mo, costs me $6/mo if I don't use the spare phone).

    The Xs Max runs typically about 1-2 mbps at the house with 1 bar LTE, just like all our previous AT&T iPhones having 1 bar LTE (the 6 on Ting has 1 bar). But I got 30-50 mbps with the Xs Max in downtown Colorado Springs, and 80-90 mbps in Denver. With a decent signal my iPhone X is usually about 60-80% as fast as the Xs.

    Here at home right now as I type, the Xs Max on AT&T gave me 1.47 down / 0.40 up, and my X ran 1.70 down / 0.01 up. However, the iPhone 6 on Ting.com wireless LTE just ran 0.15 down / 0.07 up. Proof my neighborhood LTE sucks.

    My Xs will drop to 4G more easily when the LTE signal gets too low, while my X tends to hand onto 1 bar of LTE even when the data speeds would be slower than 4G. That's why I usually just turn off LTE on the X when I get home, in case I take it with me on a walk without WiFi.

    WiFi - after the 12.0.1 update, WiFi on 2.4/5.0 Ghz Time Capsule jumped from 25-30mbps to now 180-200 mbps, like the X, while the iPhone 6 is consistently at 25-30 mbps on the time capsule.

    AT&T Model (Pre-Order)
    F2LXC (10th week)

    No problems prior to the 12.0.1 update and it didn't really make any changes to the performance. Both Wi-Fi and LTE are working great. WiFi performance is especially greater than my X in the same locations, usually by as much as 50%.

    XS MAX T-mobile factory unlock
    256 GB
    GOLD
    Got at apple store 2nd week after release
    Zhengzhou 12th week

    Having horrible LTE connection at home always had full bars with samsung phones..This one only getting 2 or 3 bars at most. Looking at signal level for LTE. Samsung has a -96 which is good and Iphone xs max has -110 which according to LTE chart fall between fair to poor almost.. wifi had issue with 5 ghz..some issue resolve on 12.0.1 but main issue where 5ghz is just very weak compare to other apple product, persist. I live in a small apartment and all my devices get 5ghz at every single corner not that max. Max struggle to get a good signal on 5ghz..

    As a result of course I'm having a lot of drop calls at home where in 10 year I never had a drop call at my location...

    Furthermore about LTE sometimes you can be in on spot and have full bar and then next second you barely have service...It look like phone is not connecting to right band at times...

    I have two new Xs phones coming tomorrow. Both are from the new Foxconn factory in Shanghai. One was built week 9 and one week 12 so we'll see what happens. I figured I'd take another chance since I have to drive to an Apple store next week to get my step-dads iPhone battery replaced for him.
