A battery that is kept at a state of charge between 40% and 60% can go through thousands of charge/discharge cycles without degrading. A battery that is always charged to 100% capacity and discharged close to 0% may only last 500 cycles before it's capacity is reduced to less than 80%. I don't believe that any of us know what state of charge the management system in the Oasis is designed to maintain on the internal battery. Since it will be subject to a greater number of charge/discharge cycles, it would be logical to manage the state of charge of the internal battery differently than the one in the case. If Amazon has done that, there is no reason that the battery inside the device cannot last just as long as the battery in the case, or even longer.

i understand your point. however, this is not practical when it comes to actual use by real people. let's say you start with a battery at 40% and it takes 30 minutes to get up to 60%. how many will be reading for a few hours to get it down to 40% and plugging it in just for 30 minutes and remember to remove it from charging in time. and with the oasis, i thought that the only way to charge the cover is to connect it to the reader itself. there is no way to charge the cover alone. trying to manage a 40% to 60% range in both the reader and the cover is not at all a practical, if not downright difficult thing to do.
