Pronounced ten S (like tennis), the iPhone XS and XS Max are the incremental upgrades to Apple's game-changing iPhone X from 2017.

They build on the all-screen, notch-laden, almost bezel-free design with more power under the hood, improved cameras, a new storage option and, in the case of the XS Max, a huge screen and even huger price tag.

Screen: The 5.8-inch OLED screen on the iPhone XS is the same as the one you'll find on the iPhone X, so it's the 6.5-inch offering on the XS Max which has really grabbed our attention - fantastic for video streaming and gaming.

Battery life: It's has improved a little on both handsets over the iPhone X, but you'll still find yourself plugging both of these phones in each night to ensure you'll get through a whole day in the morning.

Camera: The dual camera setup on both the iPhone XS and iPhone XS Max is fantastic. The Smart HDR mode makes images even clearer, brighter and more detailed, and Apple's famously intuitive interface makes snapping great shots a breeze.

Mini verdict: If you're after the latest and greatest iPhone, look no further. And if your hands are as big as your bank balance, the iPhone XS Max takes Apple's smartphone to a whole new level with plenty of additional screen space.
