First Verizon vs AT&T vs T-Mobile's iPhone XS download speed tests show huge jump over iPhone X

First Verizon vs AT&T vs T-Mobile's iPhone XS download speed tests show huge jump over iPhone X
The new iPhone XS and XS Max flaunt faster cellular modems than the iPhone X, and it shows in testing. Research firm SpeedSmart ran the Verizon, AT&T and T-Mobile models of the iPhone XS or XS Max through its LTE speed testing routine, and the results above are pretty telling.

The new OLED display iPhones scored two to three times faster download speeds than their predecessor the iPhone X which doesn't have a Gigabit-class LTE modem. The difference in upload speeds was less pronounced but still significant, so you can rest assured that if you get the XS and XS Max you will take full advantage of whatever download speeds Verizon, AT&T or T-Mobile can muster in your area. 

Unless your unlimited data gets "de-prioritized," that is. When we couple the new modem with the blazing 7nm A12 Bionic chipset, the new iPhones' performance is shaping up to be pretty svelte, on or off the carrier grid.

Hey, its almost as fast as my S7! Although to be fair, who knows how the network varies from the location tested and where I live.

This only mean that the new modem used on the new iPhone Xs and Xs Max are on now on par with its counterpart Android Flagship devices (S9, Note 9, Pixel 2, G7, OnePlus 6,etc) using Qualcomm modem. The iPhone Xr is still using the old modem similar to that of the original iPhone X.

They are using none Qualcomm modems. You all should be happy. Qualcomm is the reason the United States gets a s**tty snapdragon instead of a Samsung chip.

The Snapdragon 845 integrates Qualcomm Technologies’ second-generation Gigabit LTE solution – the Snapdragon X20 LTE modem, which supports LTE Category 18 peak download speeds of 1.2 Gbps, up to 5x carrier aggregation, License Assisted Access (LAA), Dual SIM-Dual VoLTE as well as 4x4 MIMO on up to 3 aggregated carriers. Snapdragon 845 also includes integrated 802.11ac Wi-Fi with advanced features that provide up to 16X faster connection setup, simultaneous dual-band support for an ever-expanding set of applications and 30 percent more capacity utilization on carrier Wi-Fi networks, compared to the previous generation. That's from the processor in most flagships starting since March of this year the Intel modems that Apple choose to use will never be on par with the Qualcomm modem used on the majority of Android phones regardless of it being Samsung or not...seriously learn that on some parts apple will never be on par with android because they are too cheap just like when they choose not to include fast chargers unlike their android counterparts

My iPhone 7 Plus is faster than these new iPhones...but to be fair...speed is network dependent.

Interesting Att went from third to first. Obviously this is just an innitial test, but is there anything different in the modem that would make this technically achievable?

My S9 Plus would still kill these in download and upload speeds.

Can't wait to try that T-Mo 600mhz band in NYC if it's in Manhattan soon.

+1 really looking forward to 600mhz support and the faster speed support. See they just lit up 600mhz in my area as well.

Simple reason is this year Gigabit modem rates had gone down to throw away levels (comparing last year). So apple started using them this year...
