A study reveals that users of the iPhone XS Max have more than twice the speed that users of the iPhone 5s on average

According to OpenSignal, iPhone XS Max users have LTE data transmission speeds more than twice as fast as users of the iPhone 5 in the United States, according to OpenSignal.

OpenSignal said it measured speed on hundreds of thousands of iPhones in the United States from October 26, 2018 to January 24, 2019 and found that iPhone XS Max's users recorded an average download speed of 21.7 Mbps on the LTE network, compared to just 10.2 Mbps for iPhone 5s users.

iPhone XS Users found an average LTE download speed of 17.6 Mbps, while iPhone 6 to iPhone 8 Plus users had an average LTE download speed of between 15.6 Mbps and 17.1 Mbps, measured by OpenSignal.

OpenSignal attributes faster data speeds on new iPhones to enhanced modems and antenna designs of these devices, such as 4×4 MIMO support in the market. iPhone XS and iPhone XS Max compared to 2×2 MIMO on the old iPhone, but the results are also probably influenced by socio-economic factors.

A person who still uses an iPhone 5 in 2019 could be a price-conscious consumer, unable to justify the cost of upgrading to a newer iPhone, for example, while using a low-cost operator offering wireless coverage lower or limited data transmission speeds of major carriers such as Verizon and AT & T.

That said, although the results may be somewhat skewed, a new iPhone should be able to reach faster data speeds than an older iPhone, assuming it's connected to a cell tower with of the last LTE equipment.
