You're going to need to break your question down a little bit better. I'm having trouble understanding what you're asking.

Up to 200 hours of standy.
Up to 6 hour usage on 3G
Up to 9 hour usage on WiFI
Up to 8 hours usage on 3G calling
Up to 14 hours usage on 2G/GSM calling
10 hours playback on Videos
40 hours playback on Music

As for how much power is consumed overnight would depend on the tweaks you have running, whether or not you have WiFi or 3G/4G left on, and whether or not your iPhone has notifications running WITH Wifi or Data. The average power consumption is 237 mA (estimated) based on a consensus of over 9 million users who submitted a diagnostic/usage, or based on statistics available on tweak/apps like BatteryLogger, BatteryDoctor and more.
