Data speeds: iPhone 5 vs. Samsung Galaxy S3 vs. iPhone 4S
LTE data speeds on the iPhone 5 will slaughter the 3G speeds you got on the iPhone 4S. CNET tests the handsets with the Samsung Galaxy S3.
Though its thinner profile and longer screen are two of the iPhone 5's top draws, I'm more interested in what's inside Apple's newest handset. Yes, after a long wait, the iPhone 5 finally adds support for 4G LTE data networks. Of course, I have to point out that a galaxy of Android phones (get it!) have long offered the feature, but that doesn't mean I'm not grateful that at long last the iPhone has caught up.

Early reviewers of the iPhone 5 have already praised the big jump in data speeds from the
Yet, you don't get the full story of LTE until you compare the iPhone 5 with its immediate predecessor, the iPhone 4S. Remember, that device topped out at 3G on Verizon and Sprint, and 3.5G on AT&T (even if AT&T
Before you get to the results, I've got a few words about how we conducted the tests. For each phone -- as a reminder, that's the iPhone 5, the iPhone 4S, and the Galaxy S3 -- we conducted multiple tests using Ookla's SpeedTest.net (available free from the iTunes App Store and Google Play). Because our review devices currently are divided between the two CNET offices, we tested the Verizon phones in San Francisco and the AT&T handsets in New York. As soon as we can, though, we'll trade each batch of phones between us so that all handsets are tested on both coasts. In each location, we used the app to ping the same server and record the download and upload speeds in megabits per second.
This report is a work in progress so we will keep adding more results when they come in and update our evaluations. At the moment, comparing Sprint's LTE results is trickier since Sprint's network. But once it reaches New York or San Francisco we'll test the same phones and add the data here.

I know it's not earth-shattering news, but both the iPhone 5 and the Galaxy S3 smoked the iPhone 4S all around. But even the LTE handsets weren't in line. On Big Red, the iPhone 5 delivered superior download speeds while the Galaxy S3 enjoyed almost double the upload speeds. On AT&T, the two devices were almost evenly matched. And on the whole, AT&T's network outperformed Verizon's.
Keep in mind that your results may vary depending on your location, the strength of a carrier's network at a given the time, and the number of people using it around you. Carrier network performance changes constantly so there's no way to guarantee that you'll get the same results as we found.
