Galaxy S9 Obliterates iPhone X in LTE Speed Tests

With the Galaxy S9, Samsung believes it has one of the fastest phones around. And now it's got the test data to back up that claim.

The testing, provided by third-party firm Ookla, concludes that Samsung's newest flagships offer faster download speeds than other phones — up to 42 percent faster, Samsung says in its summary of Ookla's numbers.

That actually squares with some of our testing. When we first got our hands on a Galaxy S9+, we used Ookla's app to see how its download speeds compared to the iPhone X's. Running the test multiple times, we logged a download speed of 71.6 Mbps for the S9+, while the iPhone X averaged 48.8 Mbps — a difference of 46 percent. The S9+ downloaded a movie trailer for The Hobbit: An Unexpected Journey in 18.8 seconds, nearly 20 seconds faster than Apple's phone.

Samsung credits its edge in download speeds to a Category 18 downlink LTE modem. Specifically, the Galaxy S9 uses Qualcomm's X20 modem, which is capable of supporting download speeds up to 1.2 Gbps. The X16 modem in the iPhone X we used in our testing has a 1 Gbps cap.

That said, it's worth taking note of the phones Samsung called out when trumpeting its download prowess. Like the iPhone X, the Pixel 2 is equipped with a modem that has a lower maximum throughput.

That won't be the case with other phones just hitting the market now. The Galaxy S9 uses Qualcomm's Snapdragon 845 mobile processing platform, which includes the X20 modem. The just-announced LG G7 ThinQ has the same mobile processor, though, as does Sony's Xperia XZ2. And the OnePlus 6, set to be unveiled this week, is going to feature a Snapdragon 845, too. We plan to see how those phones compare to the impressive network speeds we've seen on the Galaxy S9.

To be fair, LTE speed is just one aspect of performance. The A11 Bionic processor in the iPhone X is a heck of a lot faster than the Snapdragon 845 processor in the Galaxy S9 when it comes to other tasks. This includes video editing, opening apps and PDFs, as well as synthetic benchmarks like Geekbench 4 and 3DMark.

    They need to offer a flagship without the curved sides so one can put a real case on it. My wife's s7 had one of those kinda cases that wraps partly around, but the screen still shatter when dropped 2 feet and hit on the corner.
    Now with her s9+ she had to go with another case that doesn't really protect the front, so she insisted on the durable case like screen protector cover for the front...well, now the screen isn't very responsive at all, and makes it really frustrating crippling such a powerful device. And, the edges serve no purpose other than to look cool when not in case, has to be in a case or else it will almost definitely have a screen or rear glass back break.

    Nickebrenner, i just bought one and have seen a lot of issues with the sensitivity although it appears it can be fixed in the settings on the phone - i have had good luck with the otterbox commuter on my phones so that and a glass screen protector are going to be my combo. Hope the above helps with the sensitivity issues.
