| Wasn't arguing that it's difficult, just that it's needed (and that I'm not expecting it to be done in practice. Because the indicator LED on my laptop doesn't do it either, despite being enterprise grade). |

| JIRA is "enterprise grade", I wouldn't place too much faith into that term. |

| ▲ | perching_aix 17 hours ago | parent [-] | | Trust me, I was using it semi-sarcastically too. This thing is slower than my old Pentium 4 would be, yet has a fast enough 30% to 3% battery discharge rate that it would make the speed of light itself blush. | | |

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. | | |
| ▲ | xxs 6 hours ago | parent [-] | | The "accurate" charging level mostly happens with specific amount of charge cycles (i.e. new). Laptop batteries suffer from higher temperature (over 60C), overcharging (over 4.22 per Li-Ion for most chemistries). |

| ▲ | perching_aix 7 hours ago | parent | prev [-] | | 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 6 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). |

| My 2023 MBP webcam light stays on for nearly 3 seconds after the webcam itself turns off. |
