Questions about the Tamagotchi Smart hardware

[KuchipatchiPod]

How long does a Smart's battery last on average?
And how bad for it is it to charge it overnight? Big risk?
Does it come with a little charging cable like the Vital Bracelet?
Can you detach it from the wrist bracelet if you want to use it like a "normal" Tama?

I haven't played with mine enough to answer all the questions, but for your last two, yup! It comes with a little charging cable and is thankfully removable from the bulky wristband!
