Hey,

I thought it’d be pretty neat, if some folks come together and discuss the schematics of the phone.

Also for your convenience a preliminary, link-collection of some of the interesting part’s datasheets:

Power Management IC (it’s actually a pretty awesome datasheet - somebody really put up a lot of effort to describe his baby): https://d1d2qsbl8m0m72.cloudfront.net/en/products/databook/datasheet/ic/power/switching_regulator_system/bd71837mwv-e.pdf

Power Stuff:

Some LDO linear (!!) regulators for the camera, would love to know the reason for using them: https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&ved=2ahUKEwik-oTlk6nmAhXhx6YKHTDaAwEQFjAAegQIAhAC&url=https%3A%2F%2Fwww.st.com%2Fresource%2Fen%2Fdatasheet%2Fldcl015.pdf&
