As the title states my battery, after a full charge, shows a drop to 90% life left after about 1 hour of moderate or no use (i.e., idle for around an hour). Then the battery discharge rate appears to be as expected from there on. And to be honest overall it seems the battery discharge rate from beginning to end, regardless of the 'quick show' of 10% loss, seems to be as expected. I have tried a couple of complete battery drains, recharging shortly after the 'quick drop' in battery juice...and of course even after a typical discharge down to 15-25%....before recharging. No change. Have I caused this somehow? Or is this a possible bug that may get fixed with an update?? Any thoughts, advice, etc. will be appreciated.
