Nah. The Oasis always runs from its internal battery, but if it's attached to the cover the cover will top it up as and when the magic gnomes in the software see fit (normally around 85%, but sometimes as low as 70% before getting topped right back up to 94). There is an I2C protocol
between the cover and the Oasis itself on two of the cover pins. God knows what's passing down there, though some of it appears to be DRM to try to stop third-party cover manufacturers who might undercut them on price (God bless our new anticompetitive tech overlords, though given the quality of Chinese chargers half those cheaper covers would probably set your hands on fire too).
In practice you don't care: it's 'as if' it runs from the case battery, because the usable capacity of the thing in the cover is equal to the capacities of both batteries added together.
