I like my work M1 macbook air, but when battery gets below 10% it seems to get very unhappy... Requires sitting on the charger for a while before it will even s

  I may be wrong, but I suspect this is because macOS fibs at/about low power to accommodate hibernation. (I see similar behavior on my intel MBP, so I doubt it’s platform specific.)

  Interesting. I usually get still 30min-1h out of my M1 MBA on a 10% charge. It usually only hibernates a few minutes after hitting the 1% mark.

    Case in point: about 12 minutes ago my laptop informed me the battery is low. It was at 10%. It's now at 9% so I will probably still get over 1h with it. Edit: I went a total of 64 minutes after hitting 10%. Unfortunately the whole OS crashed at that point. I have been having issues with running 2 network extensions simultaneously, and I have a feeling the crash was more related to that than to running out of battery. It took 10s after I plugged it into the mains for it to respond to the power button. Had this been a regular hibernate instead of a crash, I would have expected to be back at a fully usable desktop in less than 30s total. Unfortunately it took about 1 minute to fully boot and reopen all apps, which all things considered is not bad at all.

  Battery charge is really an estimate, not an absolute measurement. It is based on , among other things, the drop in voltage as the battery charge gets low. If your battery management system is a little off in calibration, that 10% could be closer to 5%.
