In our testing, we brought the two devices out to three different locations in the greater Philadelphia region and used Ookla’s Speedtest.net app for the iPhone. At each specific location, we ran the speed test three times each to get a reasonable set of data for the comparison. Moreover, we noted both the calling quality put out by the two at each location and the amount of bars that were present during the test. And here’s what we found out.
As a whole, AT&T iPhone 4 fared better in almost every aspect except for calling quality – with that, there is just a prominent amount of static heard with it. Meanwhile, the results didn’t favor the Verizon iPhone 4, but its lively calling quality makes for the better experience between the two. Numbers can make a sharp statement in this test, but in terms of the actual real world experience with web browsing on the handsets, there honestly isn’t going to be a drastic performance boost with either device. In fact, they seemed to relatively load new pages in just about the same amount of time – so it’s not going to make much of a difference on the surface; despite the better numbers put up by the AT&T iPhone 4.
