Your mobile phone is connected. Or, at least, it should be. Whether you make lots of calls or just scroll through your Instagram feed, staying online with your carrier’s LTE network is absolutely critical. And while this year’s flagship phones all perform pretty well at that basic task, the LG V40 takes the crown as the best.
We’ve been working with Cellular Insights for a few years now to periodically test the RF reception on each year’s leading smartphones, as those tests require specialized lab equipment we don’t have in PC Labs.
For this year’s RF testing, we included a whole bunch of recent phones. We’ve collected results from the iPhone XS, XS Max, and XR; the Samsung Galaxy Note 9; the Google Pixel 3; the LG V40; and the OnePlus 6T. From last year, we have data on the iPhone X, the Google Pixel 2, the LG V30, and the Samsung Galaxy Note 8 as well.
All of the Android phones we tested this year have Qualcomm’s new X20 modem, which promises up to 1.2Gbps speeds. On paper, that’s superior to the Intel XMM7560 in today’s iPhones, which offers speeds of up to a gigabit. Curious about previous test results? See:
The X20 allows for 12 data streams of 100Mbps each. A 20MHz LTE channel with two spatial streams (2×2 MIMO) accounts for two 100Mbps streams; a 4×4 MIMO carrier accounts for 4.
Our lab tests look at performance with a single 20MHz LTE channel—so, up to 4 streams. We’re looking for sensitivity as the signal fades, not the absolute maximum speed that can be pumped through a modem.
We couldn’t have done these tests without Rohde & Schwarz testing equipment. R&S provided Cellular Insights with the cutting-edge CMWFlexx solution consisting of two CMW500 Wideband Communication Tester boxes, a CMWC Controller, and
We saw R&S’s solution recently at Mobile World Congress Americas and we were blown away by its power and flexibility. The CMWFlexx can simulate pretty much any signal condition you can think of, including arcane band combinations, signal handoffs, and even 5G. It’s used by both handset makers and wireless carriers to test and verify their phones.
It’s a Tight Race
For most levels of signal, there isn’t a huge difference between this year’s premium smartphones. Putting five models on this chart makes it a bit hard to read; the major takeaway is that the OnePlus 6T is a notch slower than more expensive phones with
In the brutal world of modem manufacturer bragging rights, Qualcomm stays in the lead, but just barely. The LG V40 has the best performance of any of the Qualcomm-powered phones we saw, overall. The iPhone XS Max has the best performance of any of the Intel-powered units. This chart shows that they’re pretty much neck and neck. I’d call the race for Qualcomm, though, because it both maintains its fastest speeds longer and manages to eke out a bit more speed in very low-signal conditions.
If you have an older phone, will buying a newer model improve your speeds? Here’s where lab test results become different from real-world results. Our lab tests check to see how phones deal with a single, 20MHz carrier of Band 4 signal. Qualcomm has been doing pretty well at that for the past few
But new phones have a lot more differences than the speeds that they can support on one 20MHz channel. Each year, companies add new frequency bands that older phones don’t support. For example, this year’s iPhones include T-Mobile’s Band 71, which extends coverage into areas where older iPhones would find none. AT&T phones with LTE Band 30 can speed along in urban areas where other AT&T phones may hit congestion.
So while the LG V40 may get this year’s crown for
