Battery drains to zero overnight

[spikerguy]

I think you must be correct, I  turned it of with "shutdown -h now" and the battery didn't drain hardly at all.

From what i understand from you must have pressed the shutdown button n closed the lid before it could even shut down and then i goes in idle and drain your battery. 

Please shutdown and wait for it to shutdown before you close the lid.  This happens often on my lenovo laptop with manjaro on it.
