But most people do use the frontlight the majority of the time. It's really only if you're reading in direct sunlight that it doesn't improve the reading experience. Having WiFi turned on is also a big battery drain, and that too is a constant drain while it's on.

I wonder if Kobo has reduce the battery life/size in order to limit the weight (which is really small for this screen size)

Without a doubt, and it was a poor design choice, IMHO.
