My mac is draining battery while plugged in. I googled about the problem and what I read that macs have issues with battery drainage while under heavy load. But my mac is draining battery while I'm just browsing the internet which is really odd to me. I have the original charger and I even tried to reset the SMC, but no luck.
Any help maybe?
Thanks.

You are wasting immense amount of resources running a so-called Virus scanner:
Launchd: /Library/LaunchDaemons/com.avast.init.plist
Executable: /Applications/Avast.app/Contents/Backend/hub/init.sh
Details: Exact match found in the whitelist - probably OK
Launchd: /Library/LaunchDaemons/com.malwarebytes.mbam.settings.daemon.plist
Executable: /Library/Application Support/Malwarebytes/MBAM/Engine.bundle/Contents/PlugIns/SettingsDaemon.app/Contents/MacOS/SettingsDaemon
AVAST reads your files, non-stop. when it is done, it starts again. MalwareBytes can be set to scan for trouble ONCE, and then be quiet.

It sounds like the new battery health management feature in 10.15.5

Alright, I downloaded the app you suggested me, and ran the diagnostics. The app tells me that there is a process that is using alot of power. Not sure what is it. I opened the Activity Monitor, and I see just standard apps that I am running (browser, VLC,etc)
Your computer performs best when connected to AC power. It can use the full output of the Power Adapter AND when doing especially challenging work will also freely "borrow" power from the battery. In some cases, the charged state may even decline during stressful work.
When used only on battery, your computer has no extra cushion of power, and WILL perform more slowly. However, for ordinary non-stressful tasks this may not be objectionable (possibly not even noticeable.)
In general, you should ALWAYS connect AC power when it is possible to do so, and only run on batteries (which will be somewhat slower) when no AC sources are at hand. There are three micro-controllers cooperating on battery and charging issues, and your Mac will NEVER over-charge.
If you are just doing some surfing using Chrome, You should know that Chrome is a NOTORIOUS resource hog. ANY other modern Browser is likely to give faster results with fewer resources consumed.
Thanks for the reply, but my macbook is almost everytime connected to the AC, and I just browse mostly with Safari and Firefox. I am really not doing anything that should drain the battery. from 100% to 90% while connected and my browser is opened or VLC. Im having doubts that my battery or my charger are being faulty.

Not to me it doesn't.
The complaint was that while used on power adapter for what appears on the surface to be ordinary uses, the battery is discharging as if it were doing high-end work.
Battery Health Management mostly widens the 'charges-up to' window to reduce stress when re-charging. this complaint is not about re-charging.

When the process using so much of your CPU cannot be identified by name, it is assumed to be kernel_task, as modified by kernel extensions. You have added these very invasive extensions:
Kernel Extensions:
/Applications/VMware Fusion.app
vmioplug.kext (VMware, Inc., 18.7.0)
vmnet.kext (VMware, Inc., 11.5.3)
vmmon.kext (VMware, Inc., 11.5.3)
/Library/Extensions
Soundflower.kext (Splashtop Inc., 1.6.7 - SDK 10.9)
intelhaxm.kext (Intel Corporation Apps, 7.3.2 - SDK 10.9)
LuLu.kext (Objective-See, LLC, 1.2.3 - SDK 10.14)
in particular VMWare Fusion is not negligible. It adds substantial overhead. if you are not using it, remove it for now.
You could try an SMC reset to get everything synchronized again:

You could post the results of EtreCheck, a "discovery" Utility that looks around at resource use:

As I mentioned in my post already, I did tried to reset the SMC, a couple of times to be exact, but no luck to solve this issue.
But the funny thing is, I removed those programs, cant find them anywhere on the system. I will check the path to remove those instances. Thanks.
