Battery drastically drained in sleep mode right after a High Sierra clean installation

I was a very happy user of El Capitan OSX. When I closed the lid with 100% battery, a week after I opened the lid and the battery was still at 100% or 99%.

Some days ago I formatted and installed High Sierra. When I close the lid and open it just 1h after, battery is being drained down to 80% in sleep mode. In a day or couple of days is over. This makes no sense and it is not acceptable.

I've been testing with Monitor Activity and closing apps before closing the lid. If I close some apps like Safari or Spotify, the battery duration is longer. But this makes no sense, It is really annoying the fact of having to close apps and open them again every time I close/open the lid. The MacBook is supposed to do nothing when it is on sleep mode, as it used to be with El Capitan, Yosemite, etc...

I really need a solution as I need High Sierra for using Xcode last version and not going back to El Capitan.

Thanks in advance for your help.
