Still 100% charged after introduction of battery health management
Since the introduction of battery health management in macOS 10.15.5, I have seen people reporting battery charge reduced to something lower than 100% if their Mac is always plugged into the AC adapter. My 16inch MacBook pro is also always plugged into the 96 watt adapter, but the percentage is never reduced and is always 100%. However, I have observed periodic short discharge (about 15 minutes) and recharge cycle, and also observed reduction of full charge capacity (a.k.a. battery health) reported by coconutBattery (and iStat Menu) down to 92%.
I wonder why the battery health management on my MBP is not behaving like what other users reported. I'm trying to convince myself that my Mac is doing the battery health management by reducing the nominal full charge capacity while still showing 100% charged, but I'm now sure whether that's how battery health management is supposed to work.
I have tried manually discharging the battery to like 20% and plugging it into the power again, but it still did not stop charging until showing 100% charged.
