Apple accused of throttling iPhone 7 performance on Verizon to match slower speeds on AT&T
In an effort to offer a uniform experience on the iPhone 7 regardless of carrier, Apple could be reducing the top speeds capable on Verizon, keeping them on par with rival carrier AT&T, a new investigation alleges.
Apple's choice of LTE modem suppliers for the new iPhone 7 series is believed to be the main cause for the issue, according to Bloomberg. Specifically, the Intel modem featured in AT&T-compatible iPhone 7 units offers slower download speeds than the Qualcomm modem found in Verizon units.
Apple for years has diversified its supply chain to help keep production levels high and also drive down costs. A similar controversy erupted last year, when it was discovered that A9 processors in the iPhone 6s were made by both Samsung and Taiwan Semiconductor Manufacturing Co.
While some benchmark tests suggested not all A9 chips were created equal, Apple said that in real-world use, the processors performed similarly. Tests subsequently confirmed those claims.
While variations in performance are to be expected from multiple suppliers, the difference between the Qualcomm and Intel modems is said to be far more pronounced: Qualcomm's X12 modem is capable of up to 600 megabits per second, while Intel's maximum speed is just 450 megabits per second.

Tests conducted by Twin Prime found that the Verizon iPhone 7 offers slightly faster LTE speeds than AT&T. But the same Qualcomm X12 chip is found in the Samsung Galaxy S7, and its network speeds on Verizon are about twice as fast as the iPhone 7.
The suggestion is that Apple is throttling the performance of the X12 modem in the Verizon iPhone 7 so that it matches the capabilities of Intel's modem in the AT&T version.
In the U.S., Apple sells two versions of the iPhone 7 and iPhone 7 Plus: The Qualcomm modem is compatible with both Verizon and Sprint, while the Intel modem can connect to both AT&T and T-Mobile.

Literally NOBODY is getting 450mbps+ anywhere.
I've never seen a more bullshit article.

Just ran it again and got double the upload speed and about the same download speed. These are among the best results I can get. 450 isn't even on the radar. Hell, 100 isn't on the radar. If the test has no real-world applicability, what is the point?
How does it have any useful meaning if they left out the inclusion of the Galaxy S7 on AT&T?
You could include the S7 on ATT only if it used the same modems in question, which from the above post looks like they don't. So that data point would be irrelevant.

It does seem like this article and the article it is based on are missing the more interesting point.
"The S7 was about twice as fast as the iPhone 7 running on the same network with the same modem chip, Twin Prime found. This was based on data from more than 100,000 phones downloading an image in large U.S. cities."
Given that the averages are a tiny fraction of the max speed of even the slower modem, even mentioning the max speeds is misleading. The question is why do Samsung phones appear to have twice the real-worth download speeds of their Apple counterparts? If that's true, then THAT is a story. "Buy an iPhone is you want to spend twice as much time waiting," could feature nicely in a snarky Galaxy ad.
