If it's not technical book I usually go for an audiobook while doing other things, e.g running, gym. Then I open the section in Play Books and skim through what I've listened, highlight important stuff and it creates a document with my highlights automatically and saves it to drive. I've found that doing this way really helps with information retention and I can do much more books with this method. Also, if anyone knows good open source alternative which would work on mobile and web in a way Play Books works - would be great to try. I've seen few libraries e.g epub.js and also NextCloud has its way to display uploaded books, but couldn't find a fully working alternative.
