The iPhone 11 gets the ultra wide lens for the best photo
The cheapest new iPhone of the three, the iPhone 11, has a mere two lenses rather than three on the 11 Pro and 11 Pro Max but it's the 12MP telephoto lens it ditches, not the ultra-wide, which has a f/2.4 aperture and 120 degree field of view.
The main 12MP wide lens has 5x digital zoom but if you think you'll get use out of a telephoto lens with 2x optical zoom and 10x digital, plus optical image stabilisation, you'll need to go for one of the Pro iPhones.
The front camera is the same on all three
It's a 12MP camera with an f/2.4 aperture and newfound 1080p slow-mo skills. Apple also says that FaceID has been improved this time around and the front facer can shoot up to 4K video at up to 60fps, just like the rear cameras.
There's a bigger battery boost on the iPhone 11 Pro
While the iPhone 11 only sees an extra one hour of battery over its predecessor, the iPhone XR, the more expensive models seem to be doing a lot more work in this department.
The 5.8inch iPhone 11 Pro will last, according to Apple, four hours longer than its 2018 equivalent, the iPhone XS, so it's good for 18 hours of video playback. Similarly the iPhone 11 Pro Max is supposed to be good for five more hours on one charge than the iPhone XS Max or 20 hours of video playback. The proof will be in the testing but if stamina is a major concern, it's the Pros that are the worthwhile upgrade here.
