Always wifi off, front light is around 20%. KOReader comes with a battery information panel so I wonder if the original Kobo OS was "lying" on battery level but I was really seeing a drop from weeks to weeks. Though, I never let it go down to zero, so maybe I still had a lot of juice and the indicator was faulty. In any case, I'm happy to see that my device is still running strong. If I were some kind of conspiracy kind of guy, I would say that the battery indicator going down was a way to program obsolescence
