Nope, i tried it all, it's like most common answer. Again whole night unplugged sleeping, without wifi or bluetooth. Opened up the laptop this morning and it's battery is on 37%, while it was sleeping my macbook lost 63% battery.

This is very serious issue for me, it's not good for the battery!

I spent some time looking for answers, and i found this:


I managed to solve the issue by typing 'sudo pmset -a disablesleep 0' in the Terminal.

I am not sure if a restart will cause the configuration to reset, but it is working so far.


I hope that will fix the issue, i just got new battery, and this is absurd, apple gonna damage/drain the brand new battery...
