So over one night you lose 5% but its suggesting you need to do a software update, and after a bit of fiddling another night you lose 1% which could be anything from 0.1% to maybe 1.5% depending on how close you are to the thresholds (ie you may have started at 29.6% which rounded up and ended at 29.4% which rounded down)
Anyway... I think the clue is probably in the fact it was downloading and preparing a software update. If it happens repeatedly then it might be something else.
