Why is it not possible to completely save the battery when on AC? i.e. charge the battery to 100% (or something close) but power the laptop directly via the charger.

- wyclif 6y agoUnderstood. So why hasn't Apple done something about this earlier? IOW, a setting that charges the battery to a maximum of 80% when plugged in?
- em500 6y agoBecause you need to predict whether people want to use it plugged in or on a full charge afterwards.
- sambe 6y agoAre you sure? I had read elsewhere that it always goes through the battery, and a sibling comment says there is insufficient power from the charger alone (not really sure how that's possible either though).
- layoutIfNeeded 6y ago>power the laptop directly via the charger Recent macbooks can't run directly from the charger. The charger is not beefy enough to provide power during peak CPU/GPU usage.
