Charged fully 2 days ago, and it's down to about 1/3 left. We upgraded her from a Touch, which was significantly better. Thought maybe it needed to be re-calibrated, so I did a paperclip reset, but it made no difference.
I'm just getting her to compile some more accurate figures, then firing off a letter to Kobo support for service info.
UPDATE: Jan 17
3 days after a full charge, it went dead on Sleep mode, WiFi off. Sent the details to Kobo, and they're supposed to be sending me a replacement. I hope it's new/near new, as this one was hosed out-of-the-box.
Contacted Kobo, explained everything I tried, and they simply said that the reader would need to be replaced. Replacement came yesterday after about 4 days, with a pre-paid return envelope.
Although I haven't had a chance to wring out the new one, I'm very happy with the support Kobo has provided.
