M1 weird battery issue

[mactinkerlover]

Ah, so I'm sure many of you were not expecting to see that title for a while. So let me explain. I mainly keep my laptop (m1 macbook pro) plugged in as I'm at my desk a lot. I hadn't unplugged it for a while, and I unplugged it today, and it quickly drained to 98 percent. A couple minutes later, it jumped to 96 percent, and then 94 percent. Then about 2 minutes later it went to 93 percent. It seems to have stabilized after 93 percent, and I ran cinebench then and it seemed to be draining like how it normally does. I ran cinebench until it got to 89 percent (for about 6 to 7 minutes if I recall) and here I sit at 89 about 15 minutes later. Do you think there was a discrepancy between the controller and the battery or something because I hadn't had it unplugged for a long time? Maybe this is a problem because it probably uses the same power management as iphone and they expect that obviously you won't be using an iphone unplugged all the time. Thoughts anyone! I think it's fine now.
P.S. it just went to 88 percent after more web browsing and writing this fourm.

It could be an app running background processes that is to blame for the battery dropping that quickly. I know Chrome has a major issue relating to battery drain, which was the main reason I completely uninstalled it on my M1 MBP.

Get Coconut Battery. It’ll tell you the real battery charge. Apple’s battery menu bar extra has a heuristic to make it look like it started on 100% when you take it off the charger. What you are seeing is probably what you supposed and normal operation.

First thing first, as anyone will tell you, being plugged in all the time will reduce battery's efficiency over time. You'll get less hours from it. Keeping that aside:

What browser are you using? (Google Chrome is a no no).
What apps are running in the background?
Check Activity Monitor->Energy Impact.

yeah, I suspected that because I was keeping it plugged in so much, the battery health management kicked in and stopped it from topping off the battery so what happened was when it was used on battery, there was a discrepancy.
Also, I just put coconut battery on and it says the battery is actually at 77 percent while the mac says it's at 82. I guess you're not kidding. Maybe apple needs to work out the kinds with the battery health management?

I use brave browser mainly, haven't had any problems with it especially now that it's native. That aside, I do try to discharge the battery at least once a month to keep the battery exercised.
