iPhone 4S Test Notes: Data Speed (It’s Slow)

October 20, 2011 Leave a comment

The new iPhone 4S is here. A re-spiffed antenna, and stuffed inside the AT&T 4S, new guts that (should) mean faster data speeds. But theoretical max speeds are not real world experiences. Here comes the comparison among AT&T, Sprint and Verizon for the fastest iPhone. Does 4S measure up against the most jacked Android phones?

The reports after the test of the iPhone 4S on AT&T, Sprint, and Verizon; the iPhone 4 on Verizon and AT&T; the Samsung Galaxy S II on Sprint and T-Mobile; the Motorola Droid Bionic on Verizon, and the HTC Amaze on Sprint, are as follow:

None of the iPhones proclaim to work at “4G” speeds, even though AT&T has billed mobiles with the same potential data speed as the 4S as “4G.” Verizon and Sprint’s iPhones use CDMA EV-DO Rev A, which has a theoretical max download speed of 3.1Mbps. The old AT&T iPhone 4 was technically capable of hitting 7.2Mbps downstream. AT&T’s iPhone 4S uses a version of HSPA+ with a max speed of 14.4Mbps downstream. Regarding non-iPhones, the Amaze 4G and Galaxy S II on T-Mobile also run on HSPA+, but a version that theoretically allows a peak downstream speed of 42Mbps. The Galaxy S II on Sprint uses WiMax for 4G speeds, while Verizon’s Droid Bionic runs on its LTE network, which claims speeds of up to 12Mbps (though we’ve seen them go well above 20Mbps). Obviously, theoretical max speeds are not real world speeds.

Every phone displayed max bars with pretty strong signal.


Numbers of People consider download a significant factor. No wonder, may be, the 4G phones massacred the iPhones, beating them by nearly 1000 percent. AT&T’s faster theoretical speeds with its iPhone 4S are faster in real life, overthrowing Verizon and Sprint on the iPhone 4S. No real gain for Verizon—  it is that Verizon iPhone 4 already had a tweaked antenna design, so it had less to gain.



Upload speeds are equally important, considering how many of us are now syncing our high-res photos and HD videos back to the cloud. The iPhone 4Ses’ speeds was not much better, particularly AT&T’s. Sprint’s iPhone 4S gave the best upload speed at 0.89 Mbps,among of those compared phones.

Overall, Sprint seems to average out the best of the iPhone 4Ses, with the second fastest downloads and fastest upload. Addition to that, one can get unlimited data. iPhones are officially slowwwww when it comes to raw data speeds.
