Battery % doesn't update when reading ?
Had Kobo Glo for just over a week, noticed that when I was reading the battery % does not drop, was hoping this to be a real good battery life. But last night I accidentally hit the home button, and then went straight back into my book, then battery % went from 38% down to 34% !!. Is this normal that it does not update when just reading? I am a slow reader and it can take months for me to get through a book, if all I did was read would the % stay on a 100% and then suddenly go off on me ?
By the way I have not yet charged the device, its still using the charge out of the box.
