It doesn't have to be charging all the time. Some laptops have "intelligent" detection of the "usually plugged-in" state and won't keep the battery charged 100% at every moment, but will allow dropping it somewhat before charging again.
I suspect MacBooks are doing this quite aggressively (while lying about 100%), since their batteries tend to last (in terms of cycles) longer than windows laptops.
- em-bee 3y agoi thought that if the battery is charged the device will simply ignore the battery and run directly from the wire. so a fully charged battery should not be affected at all. repeatedly dropping down and recharging sounds like a bad idea.
- The_Colonel 3y agoBased on my limited understanding it's not that simple. At least some laptops still use battery power during power spikes even when plugged in. > repeatedly dropping down and recharging sounds like a bad idea. I noticed this with my Dell Precision machine that it dropped to 99% and then re-charged to 100%. It was plugged-in 24/7. You can normally configure this in BIOS, but it was locked in my computer by my employer. Unsurprisingly, the battery swelled within a year. OTOH, I'm not sure how much more damaging this is, given that even just keeping the battery at 100% for long periods of time is damaging.
