Battery drains SIGNIFICANTLY after shut down
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 :))
Here is a coconutBattery screenshot:
What happens if you fully shut down the system and disconnect the charger? With nothing plugged in.
Lets take a look at the batteries health, install this gem of an app! CoconutBattery post a snapshot of the apps window for us to see 在已经存在的问题里加入图片
Also are you using the original Apple charger and the USB-C cable or something else?

@danj Thanks for your reply! I have attached the coconutBattery stats in my post. I am actually using Xiaomi's 65W USB-C charger since the original Apple 61W charger was broken. This Xiaomi's 65W USB-C charger is USB-PD compatible and I did ensure that the specifications of the charger to be compatible with the MacBook.
About your first suggestion: do you mean I have to first shut down the Mac WITH only the charger plugged in, then after it shuts down, unplug the charger and see what happens?
you meant just shutting the Mac down completely without literally anything connected?
Because for both scenarios, the same battery drain when the machine should be off after shut down did persist.

Independent of the logic board your battery while still good, is running up the cycle count for now you may want to leave it unplugged so you don't wear it out prematurely.

I have the same issue/problem.
I've never used another charger, only the official Apple one.
The Apple store says that it is a failure of the motherboard and It must be change: 500 euros.
I have my macBook Pro with touch bar 3 years, practically without use and for 1 month it loses 25% of battery every 24h.
I have made a claim to Apple but nothing.

I am facing this too, I never had any damage or liquid spilled, etc. Even I always use a cooling pad and the original charger came with Mac. I used to charge Mac only twice a month since I don't use it other than checking emails but after the latest IOS update, I did 7 days back I notice when we shut down or put in sleep mode it consumes battery 3 times faster then while working. After the latest Mac update, I have recharged it more times than I recharged in the whole year. Even when you put to sleep it automatically wakes up, when shut down it automatically switches On some circuitry. After monitoring closely the apps and processes, I could figure out only the following reasons;
1. Mac book iOS update (10.15.5) latest version has a bug.
2. Hacked and Malware is running in the background. (from apps installed/updated by me: Zoom(install)/Microsoft Office(update)/ online game /added 1- extension in chrome)
3. The most possible reason is app monitoring Camera & Mic and keeping it ON.
