No, no, put your phone away. I mean write it down - an old-fashioned pen and paper method.
There's just something about forming words on paper that helps it stick in your brain better. Not only are you processing auditory or visual information, but you are also absorbing it by focussing on your words on paper. Form the information into your own words, whether it be bullet points, or long, drawn-out sentences. Let that ink flow, and then go back and read it again, checking for mistakes.
