Title:

Battery drains SIGNIFICANTLY after shut down

Text:

Hi, experts! I really hope to solve this problem as it has been drilling me for weeks now.
 
When I shut down my Mac, the Mac shut down correctly and I closed the lid. Left it in my desk until morning. In the morning, I felt that the Mac was warm to the touch and when I turn on, it boots up with Apple logo (like a normal startup, so it wasn’t sleeping) and it asks for my password before I could use Touch ID (so it wasn’t sleeping). '''BUT the battery had drained from 100%''' (when I shut it down) '''to 5%, if not completely 0 mAh left in the battery''' (literally 0% and won’t boot unless plugged in) '''when I turn it on'''.
 
I find this behaviour rather frustrating and it definitely consumes my charge cycle. When I shut it down and left it for some good 2-3 hours, it also drains around 20-30%.
 
Yes, I have once removed the Logic Board for cleaning (after some minor liquid damage around the iBridge Bus, which caused camera, Touch Bar, and ambient sensor to no longer work). But I made sure everything was dry and cleaned all the corrosion with 95% ethanol before putting everything back together. Couldn’t be I missed something that causes this weird problem right?
 
Things I have tried:
 
# Resetting the SMC and NVRAM (and even T2 chip) multiple times.
# Reinstalling macOS (I used 10.15.2 and tried downgrading + fresh install 10.14.6 to no avail).
# Shutting the Mac down and not even touching the lid. So, left the Mac open after shut down for hours, and yet it drained too.
# Turning off Wi-Fi before shutting the Mac down.
all to no avail.
 
Weirdly enough, if I just sleep the Mac, the drain was normal (just 1% drain overnight). Shut down, which was not supposed to drain any battery, was actually draining A LOT (even if need power for startup or shut down, those maybe drain around 1-5%, not 20%).
 
Please advise me on what to do. Thank you so much :))
