Li Ion battery life is a much more complex issue than your rather over-simplistic description.
For example, it seems likely that a typical usage pattern of an Oasis (certainly mine) would involve the device battery undergoing frequent top-up charges (being returned to the case between reading sessions) after partial discharges, rather than deep discharge/recharge cycles - this usage pattern will help prolong the battery life.
There are also other design factors which affect the battery lifetime - limiting discharge and recharge currents, trading off capacity vs. lifetime by restricting maximum charge levels etc. etc.
