When it comes to smartphone cameras, iPhones have traditionally been close to the top of the class, if not on the very top, according to some. In recent years, however, as low-light performance became increasingly important in smartphone photography, iPhones have had some troubles keeping up with the competition. Even the iPhone X, which is otherwise capable of pulling off some stunning shots when there's enough light, didn't quite manage to stun me with its low-light performance when I put it to the test against the Galaxy S9, the Huawei P20 Pro and the Pixel 2 XL.
