Although I no longer use an iPhone, I do always find DXOMARK’s benchmark testing interesting for the various flagship phones. It shows too that a megapixel number is not what you should compare one phone against another on.
I always try to compare based on like for like tests done between the various devices.
Spoiler: iPhone 16 falls behind the Pixel 9 and 8 cameras. But still it is worth “zooming” in on the aspects that are important to you as none of the phones perform equally across all the different aspects measured.
