Regarding the battery drain - I did some basic testing on my end. I think you have to make sure the wifi and bluetooth are off before putting the reader to sleep. After I started doing that, the battery drain was only about 2% a day, which is not bad. Reading around in forums, it seems bluetooth being ON continuously is a big battery drain, with multiple posts reporting 2 to 3% drain per hour, even when the reader is on sleep. Seemingly the implementation is a bit buggy and often bluetooth remains ON in the background, even when the reader is on sleep and drains the battery continuously. So best to make sure it's actually off in Settings before putting the reader to sleep. Not sure how much drain wifi being ON causes, but no harm in keeping that off as well.
Regarding your query about Nickelmenu - It's a convenience menu that gives some options on the main screen itself -- like Reboot, Shutdown, Sleep, Dark Mode etc. You can set up options to force connect the USB (so you don't have to unplug and plug the cable to the computer again if you are charging using a computer and then want to transfer stuff). There are some options to some games like solitaire, sudoku, word scramble etc.
Nickelmenu is indeed nice to have, but it's not essential by any means. You are not missing anything if just need KOReader. Getting it back is easy -- just transfer the TGZ file into .kobo folder again. You can play around with it to see if you like any options. But don't sweat it too much if you find getting it back to be a chore. You are not missing out on anything major. End of the day, the core utility of the eReader is to read books. We spend hours reading a book, and barely a few a few seconds on the device's main menu to just open the book.
