I don't have sd card... and ok so clearing cache in recovery does pretty much the same thing as factory reset... I think I am going to pass then because I did a factory reset and my battery not sucks donkey you know what.
Now clearing cache only in recovery does not wipe all that stuff. And as far as sd card, that refers to internal as well as external. Pics won't get wiped with factory reset or cache clear.
