Actually, my 32GB external card is more full than 80%, and it takes about 30 seconds to "cold boot".
But why not just put it into sleep mode when you don't use it, instead of powering it off? Battery life is still tremendous even in sleep mode, and depending on your usage and needs you could probably avoid connecting it for recharging (either to PC/USB or AC/adapter) for many days.
At the very least you could probably get away with putting it in sleep mode all throughout the day whenever you use it, charging it just once overnight, and "cold booting" just once every morning (or whenever you connect to the PC to maintain music files). Then put it in sleep mode and go in/out of sleep all throughout the day.
Battery life is huge, so why not sleep?
