The iPhone 11 - the successor to the iPhone XR - might be showing its age a little bit now but it packs in good spec and manages to do so for a lower cost than many would expect - this is the one to go for if you want a good value iPhone and don't mind tracking down an older model.
The iPhone 11 was a big surprise, packing more advanced technology (namely in the camera capabilities and the processing power under the hood) at a lower cost than the iPhone XR's price in 2018. It combines a large 6.1-inch display with a premium-feeling body, and comes in an array of colors too.
It's worth noting that the iPhone 11 isn't Apple's newest numbered smartphone - that's the iPhone 13, which launched in September 2021 alongside the tiny iPhone 13 mini, the iPhone 13 Pro, and the bigger iPhone 13 Pro Max.
These didn't improve much on the iPhone 12 range that released in 2020, but they're still the most powerful Apple phones on the market.
