| > The main culprit is that anyone estimating battery life in percentages. I thought this was a solved problem, like, decades ago? At least I remember even the first gen MacBooks having accurate battery percentages, and it’s a more vague memory but my PowerBook G4 did too I think. |

| No, I think it's fairly easy to see that a third of the charge suddenly disappearing is a fairly uncommon behavior. Same for your Windows idea... |

| ▲ | xxs 5 hours ago | parent [-] | | "A third" is again fraction/percentage - it's still a representation stuff that depends on charge and charge cycles... and likely previous over charging and heat (Li-Ion doesn't like heat). To put it simply: the charge level, usually, is just a lookup table for voltage (not under load). |
