Battery usage.
My device is 4 days old and Is it normal every time I woke up my battery lowers by 5-6% overnight (6-7 hrs) to be exact? My Wi-fi, bluetooth, data and etc. are disconnected and no background apps running.
Thank you.

If the device is powered on it still uses a small amount of power just to keep the system running, the clock going etc. I would not be concerned.
