I looked at the Apple’s website and noticed that they were giving focal lengths for each camera but no sensor size. On one of their camera they give the focal length and field of view. So I took my P-Cam app (a cinematographer app to do camera and lenses math) and for a camera to have a focal length of 13mm and a field of view...
Now that the 15 has USB-C, I’d like to see if it correctly supports USB-PD. Is there any way to tell the charging speed when you plug in your phone to charge? With my Android it would say “Charging Slowly”, “Charging” and “Charging Rapidly” or I could use some apps. I haven’t found anything with my iPhone though.
