My battery will go from 80% to 10% in 2 days if I leave it on sleep.

I have never experienced this before with a MacBook. I have read many people complain yet no solution.

There may be other devices on your network waking your MacBook via network access. Go to System Settings -> Battery -> Options and see if your Macbook is set to wake for network access. If it's set to always, change it to only on power adapter or never.

It is on off. This is ridiculous.
 
An external SSD may be draining the battery. Disconnect external peripherals and see if that helps.
 
What do the logs in /var/log/powermanagement say, does your machine wake up frequently? What does pmset -g say, perhaps it doesn't even go to sleep. You can connect a USB mouse to see via its light whether the system is really sleeping or just has the display off.
