I thought keeping a MacBook plugged in was advertised as OK (Even said to be BETTER) since the power is being drawn from the AC source rather than the battery.

I thought keeping a MacBook plugged in was advertised as OK (Even said to be BETTER) since the power is being drawn from the AC source rather than the battery. What’s the deal, is it better to leave it plugged in, or not?
- mr_toad 7y agoGenerally speaking it’s better to keep it plugged in than to repeatedly charge and discharge it. But it’s even better to keep in plugged in at 80% charge instead of 100%.
- Nyra 7y agoReally? I'm not very knowledgeable about the subject but I always understood that discharging the battery was healthy. Is there somewhere I can read up on why that is?
- aeyes 7y agoIt is healthy, but discharging to 0% isn't and keeping it at 100% isn't either. It is best to plug in at 20% but only charge to 80%. Then every half a year you do a full charge to 100% and a full discharge to calibrate the battery management. But sadly that can't be configured on a MacBook.
- wyclif 7y agoBut...how do you keep it plugged in at 80% charge without hitting 100% relatively quickly?
