    Currently a lot of XS & XS Max users are having LTE issues. I’m not sure whether or not I’m apart of that bandwagon now.

    I noticed that my iPhone X has been pretty sluggish over LTE lately, however I don’t know whether to blame AT&T for this since they haven’t been too fantastic either.

    iPhone X with “4 bars of LTE” gets around 2-3mbps download and 2-3mbps upload. Something definitely seems off. I tested this against a Verizon iPhone X with “2 bars” at the moment of testing and got around 40-60mbps download and 2-3mbps upload. Which I was baffled to see. Both iPhone Xes are running iOS 12.

    Contacted AT&T about it and their support team escalated my issue to a “network issue”. Not sure what that’s gonna do for me but I’m not very hopeful.

    It is very much possible that Apple may have throttled iPhone X so that it’s performance is seen to be lower than XS.

    It’s bad enough that it’s being throttled because of the lower performance of the 2017 Intel chip.

    My X on AT&T is also having this issue (some days). When on WiFi my download speeds are about 50 Mbps, which is normal being my WiFi plan is 50 Mbps. When I switch to LTE and run a speed test I get only 10 to 12 Mbps, I just ran one now on LTE and pulled in about 35 Mbps. So it's a hit or miss. My X seems to constantly switch between LTE and WiFi a lot too, Safari says "Your iPhone is not connected to the Internet" frequently. Facebook fails to load, etc. I have the Intel X.

    It's been around/explained before. The difference in chips Vzw qualcomm vs ATT/T-Mobile Intel and per their network. (iPhone X). And with XS/Max going Intel. Definitely, an issue somewhere. Hope, it can get fixed with a modem firmware update (towers) b/c I'm really on the fence of dumping ATT and switching to Vzw (ugh). Like the one, some good days some bad days.

    Just sounds like bog standard network congestion to me, on o2 in the UK that’s a very common issue.

    Some areas I can pull 30Mb at 7AM on 5Bar LTE only to have it drop to 1-2Mb on 5Bar LTE at 11AM when everyone’s devices are using mobile data rather than home WiFi.

    Doubt it’s an issue with the phone, more likely just a useless network.

    O2 have major issues at large events, where even LTE can grind to a complete halt and the phone drains half its battery trying to send a simple picture message, yet someone on EE next to me can have less signal but is still able to use their device as the network has more towers/better towers.

    Qualcomm-based offering is denoted by the A1865 model number and A1901 model number for the Intel LTE model.

    Settings, general, about, tap on model.

    Take a look at the top results, that is o2 on a congested bad day with a decent signal, then look underneath it pulling over 80Mb down.

    Also o2 doesn’t have much spectrum to play with like EE so can’t do a huge amount of carrier aggregation and stuff either which means my headline LTE speeds are slower anyway.

    I concur with this, all iPhones in Britain are Intel ones and mine had hit 85Mb/s on the screenshot I posted.

    Before jumping into any conclusion, you should check for network outages or congestion in your area. Even for home internet, there are peak and off peak hours where you’ll get much better download speed during the night than during the day. If it is the device, all you can do is basic troubleshoot. Restart the device or a network reset. Wait for a carrier update or software update to update the modem firmware. Other than that, it would just be a blaming game between carriers and Apple. Submit carrier ticket and submit feedback to Apple to look into it.
