It is believed that different iPhones have been capable of different mobile speeds over the years, as not only the phones themselves are improving but also the infrastructure they are associated with.
Now a new study of OpenSignal has looked at the cellular performance of some of Apple's most popular iPhones dating back to 2013. The results provide interesting reading, though none of them are particularly unexpected.
As the figures from OpenSignal show, the current crop of iPhone XS and iPhone XS Max handsets is about twice as fast as iPhones a few years ago, especially iPhone 5, iPhone 6 and iPhone 6s. It is also clear from the figures that while there have been some big jumps, nothing has changed as far as speeds are busy in 2015, 2016 and 2017. They cover the iPhone 8 and iPhone 8 Plus backwards, through the iPhone 6s and iPhone 6s Plus  In OpenSignals measurements, they experience significantly slower cellular network speeds than those with newer iPhone models. In the US, iPhone 5's users experience 4G download speeds of just 10.2 Mbps compared to 21.7 Mbps for the latest iPhone XS Max.
We know that the current crop of iPhones has improved the mobile speed thanks to their new, upgraded antenna systems. These figures show it in graph form when compared to older phones.
The other good news here is that the latest iPhones seem to match what Apple would suggest they are capable of, although the iPhone XR is slightly lower than the iPhone XS and iPhone XS Max, which may be something worth remembering when you make a purchase decision.
With the iPhone that will receive a new update towards the end of this year, we have to wait and see what is around the corner. Apple is unlikely to use 5G this time, despite the 5GE logos that have started to appear on some key iPhones.
