I've been having an issue in the last few weeks with huge battery drain when I close the lid and MacBook (AIR circa mid-2014) enters sleep mode. I have read some threads on here that it has been happening to people since Mojave update. On the day it started to occur I didn't do anything out of the ordinary apar from connect to a new network - which I have since removed. Have tried all the normal suggestions SMC /PRAM reset, fresh install of Mojave and have changed various power settings like TCPKeepalive and Hibernate mode to 25. Nothing has worked and it'd driving me crazy. Checking to see if anyone still has this issue? Have you just accepted it and shut down each time. This is really annoying as shutting down and restarting so many times during the day becomes very tedious and frustrating, when previously all I needed to do was close the lid!
