I think the wifi thing is a red herring. The further your Kobo is from a good wifi signal, the more power you will use as your Kobo will have to transmit back across the same distance/interference. This will make your battery go down much faster, and I don't think it's related to the sleep issue.
I generally only turn my Glo off rather than sending it to sleep, and I've had it last for 10 days reading 3-4 hours a day on average. I have seen occasions where I've allowed the Glo to sleep, and then turn itself off, and then a few hours later, I turn it back on to see a chunk taken off the battery ie, more than if the Glo had been on and being used to read books.
So I think there is an issue with the Glo going automatically from "sleep" to "off". I think it's not only not switching off properly, but that it's getting itself stuck into some kind of loop or race condition where it's actually burning more power than normal, possibly running the CPU at 100 percent instead of going off. I think it's a bug somewhere in the firmware that can be fixed by an update.
