You have to charge the 3DS once you open it as the battery is not fully charge out of the package.
It does offer more than 4 hours of play time per full charge and you can keep it in sleep mode for days without problem (I do). I've not manually powered down my 3DS in months.
I'm also quick to throw mine on the charge cradle when I'm not using it just as a habit. It just makes for a convenient place to set it and charges the battery in the process.
