If I leave it another hour on the charger, the battery remains at 100% after I turn it on.

It's a characteristic of Li-Ion/Li-Poly batteries. They will charge relatively rapidly up to about 90% and then the final top-up charge progresses a lot more slowly. It's probably a function to prevent overcharging, particularly from some of the cheaper chargers there are around. Sounds like the, rather primitive, charge indicator on the Kobo is showing 90% odd as a full charge.
