    Apple's iPhone XS and iPhone XS Max launched last Friday, and shortly after, some customers who purchased one of the new devices started noticing an issue with LTE and Wi-Fi speeds and connectivity.

    According to multiple threads on the MacRumors forums, iPhone XS and iPhone XS Max users are experiencing connectivity problems with Wi-Fi and LTE on the two new iPhones when compared to other, older Apple devices.

    Multiple users have said that there are noticeable differences in cellular reception between the iPhone XS models and the iPhone 8 and iPhone X, with a 15-page thread suggesting this is a widespread problem that quite a few people are noticing. As described by MacRumors reader onepoint:
    Users are noticing fewer bars and poorer signal on iPhone XS and XS Max compared to devices like the iPhone 8 and iPhone X, especially in areas where signal is weak. Many of the complaints come from Verizon users, suggesting the issue could potentially be carrier specific. Multiple AT&T users, for example, have said the signal is the same or better, while Verizon users are seeing signal issues.

    Some iPhone XS owners have theorized that the issue is related to Qualcomm vs. Intel modems. The new iPhone XS and XS Max are using Intel modems, while older devices used a mix of Qualcomm and Intel modems. AT&T iPhone 8 and iPhone X models used Intel modems previously, while Verizon iPhones had Qualcomm modems. As explained by MacRumors reader radiologyman:
    Some AT&T and T-Mobile users are, however, complaining of connectivity problems too, while others have noticed better signal, leading to a confusing mix of user reports.

    It's not clear if modem differences are causing the perceived connectivity issues that iPhone XS and XS Max owners are noticing or if there is a genuine bug with the new devices, but in the days following a new iPhone release, there are often carrier updates that can solve connectivity problems.

    Given the confusing mix of information coming from users on the forums, the LTE connectivity problems may be related to software and could be fixed through the aforementioned carrier update or a software update from Apple, but we'll have to wait for more information to figure out exactly what's going on.

    In addition to the LTE problems, there appears to be a separate issue with Wi-Fi. On the MacRumors forums, users began noticing slower Wi-Fi speeds on iPhone XS models compared to other Apple devices, which readers quickly deduced was a 2.4GHz vs. 5GHz Wi-Fi issue.

    It appears that the iPhone XS and XS Max are preferring 2.4GHz networks over 5GHz networks when connecting to routers that use the same SSID for both the 2.4 and 5GHz bands. From MacRumors reader playtillyadrop:
    The majority of people experiencing slower speeds found that their iPhone XS models were indeed connected to the 2.4GHz network rather than the 5GHz network. In our own testing, we found that when comparing an iPhone XS Max and an iPhone X, the iPhone XS Max connected to the 2.4GHz network while the iPhone X connected to the 5GHz network.

    With routers that do not have separate SSIDs for the two bands, it can be difficult to tell which you're connected to, leading to perceived slower connection speeds.

    This is clearly a bug that needs to be addressed by Apple through an update to make the iPhone XS models prefer the faster 5GHz network to the 2.4GHz network, but in the meantime, providing separate SSIDs for the 2.4 and 5GHz bands can allow you to make sure your iPhone is connected to the 5GHz band at all times.

    Some users have also had luck with resetting their network settings and/or forgetting their Wi-Fi network and reconnecting, but the iPhone XS models appear to default back to 2.4GHz often if not made to connect to the 5GHz network.

    This connection issue appears to be at the root of most of the slow Wi-Fi complaints, but there have been a few other complaints of poor connection speeds when connected to a 5GHz network, so it's possible there's also something else going on.

    We've contacted Apple to ask about both the Wi-Fi and LTE issues that customers are experiencing with the iPhone XS models and will let MacRumors readers know if we hear back.

    Battery life isn't too stellar for me on the XS right now, either.

    I guess it depends what version of the phone they have. I don’t know if they all share the same modem now, but the 7s has either an Intel or Qualcomm modem and the Qualcomm in mine is clearly the faster and better one.

    Ironically mine is better than the X!

    Wifi works in place that was always dead for me, but better still - there's no celluar signal at home but when I left, though the X would show full 4G but never work until I put it in Airplane mode for a while and then let it "search" for the network again.

    So far the Xs has been flawless it gets the 4G network earlier and it works straight away - I always assumed it was the network around here that was poor as other people have problems, but maybe the X was actually faulty. I don't know, but i'm chuffed with the Xs so far!

    Was having issues with WiFi and I reset my network settings. All was great for about 6 hours, then issues returned. Hoping for a speedy 12.0.1 update to address this.

    Turn the brightness down or maybe background refresh for all but your most used apps. Maybe set some apps to turn on GPS while using instead of always. If you’ve done all of this already then maybe something is wrong or the battery life just isn’t that great.

    I have been having same issue with Wi-Fi on my iPhone X for months, Apple even replaced phone in July, as it was suspected that Wi-Fi chip was bad. Still have issues.

    I noticed the WiFi one as well. How it would jump over to 2.4 when it should stay on 5ghz unless the signal is really bad. I work for a network vendor and do wireless for a living and noticed this one right away. Also when it’s on 2.4 it’s performance kind of sucks compared to other devices I have on the same 2.4

    Ohh and no matter who tells you. Most of the time with wireless it’s driver issues not hardware in most cases. The drivers are bundled in the iOS so cant be fixed separately.

    Intel, for the win! </s>

    I had a feeling this story would be coming, and I'm glad I stuck with my iPhone 7 with a Qualcomm modem in it. I think the XS/XS Max will be the only iPhones that use all Intel modems across the entire lineup. Apple has already told Intel they won't be using their 5G modems in future iPhones, which subsequently caused Intel to shelve their 5G modem development.

    I am having issues with my 8+ ever since iOS 12 where WiFi gets dropped repeatedly and rapidly even if I'm right next to the router. Started since I got iOS 12. Not sure if this is related but... I'm definitely blaming iOS 12 - haven't seen any others complain about this tho. (5Ghz).

    Would be helpful to see some video of side-by-side LTE and WiFi tests between an XS/XS-Max and a previous gen phone.

    Battery life will suffer if your signal is low too.

    Before you buy an Xs or XsMax, better read about the Antennagate ReduXS.

    iPhone 7, still a great phone. Half to a third of the price of the current Xs/Max -- and with quality radios. Sticking with my Qualcomm variant until iPhone XI.

    Early adopters complain of bugs in newly released products? Color me shocked.

    I was always finding my iOS devices slipping back to 2.4GHz so I just block their MAC address from that radio on my router so they can only connect to 5GHz.

    Luckily for me I have Eero and don’t have the option of changing my 5ghz network name. My XS max is still restoring from iCloud, started 3 hours ago. And this is on fiber...

    Apple please fix...
