Battery draining while charging

"Battery draining while charging: [...]I was wondering whether other people have the same issue or whether this could be part of a natural process that keeps the battery's chemical reactions going or is it a reason to be concerned? /The laptop has been used for the average time of a normal user for roughly 10 days./"

Perhaps this is a Faulty Device?:

If such is the case, then contact Apple - you have up to 14 days to return this and get your money back. After that, you have a one-year, limited-warranty. If you purchases an AppleCare protection, it could add up to 2 years of protection on top of that. So, in case it is a faulty device, have this looked at.

Apple Send-In Service:

As for having a 2020 Mac. You have a one-year limited-time warranty. At the moment, with the Coronavirus Pandemic, many, many Apple Stores are still closed at the moment. So, Send-In Service may be the only available option for getting this serviced. So, have Apple take this in through Send-In Service. They will send you a box; you would ship it out to Apple; their engineers would look at it; and the would send it back to you.

"Battery draining while charging: Hello guys, I recently got a new Macbook Pro (2020, 13') and noticed that its battery is draining while charging every day (also, nearly at the same time) until it reaches around 90% capacity and then goes back to 100%. /Meanwhile, the power management system indicates "Normal" state of battery and "Battery not charging". [...]I tried resetting the SMC several times but it did not make a change.?"

Reset the NVRAM:

Caches for temporary settings may be getting in the way here - so reset the NVRAM along with the SMC.
