There is something I dont understand, I thought that mobile data drain more battery then Wifi when used, so wouldn't turning off Wifi and using Mobile data instead will create more battery drain during the sleep ?

Yeah, it is, in theory.
In practice keeping Wi-Fi on often causes certain wakelocks (like wlan_rx_wake) to drain more battery by keeping CPU active than a power needed to maintain a mobile data connection. The amount of time these wakelocks may take place depends on Wi-Fi router, I guess; at my home keeping Wi-Fi on during the night eats a looot more batter than when it is off and mobile internet is used instead. Also note that when Wi-Fi is on, all applications are aware that there is a high speed unlimited connection available, and thus may behave differently (start syncing heavy files, etc.).
