What you do is dependent on how you use the device and what makes sense for you. For sideload only users, turning the WIFi off makes sense. For people only reading books from Kobo, it makes more sense to have the WiFi on. And if you read books from Kobo on multiple devices or the apps, then having WiFi on makes a lot of sense to sync your reading status. It is a question of convenience: WiFi on all the time vs. turning it on when needed and some unknown extra battery life.
Of course, if you are constantly using WiFi, such as when using the browser, then it will drain the battery. But, that will also mean you have the CPU, memory and screen running hard. And that drains the battery as well. Which is the greater culprit, I have no idea.
