Is the MacBook Pro supposed to safely shut down at 1% battery?

[Woodcrest64]

Just wondering if the Macbook Pro is suppose to safely shut down at 1% or 0% battery life or does it just run right to 0% and the battery is dead?

I imagine it would safely shutdown instead of just cutting off.. I have never actually seen it happen though because the batteries are fantastic and it usually just sticks at 1% for a long time before I can be bothered to plug it in.

You shouldn't be letting it run that low anyway. After 10% you better plug it in.

This really shouldn't be a thing that you do regularly, but if I remember correctly, there is a warning and if you ignore it, the computer shuts down rather abruptly.

The charge percentage isn't an accurate representation of the actual charge anyway.

Just leave it on the charger when you can and run it from the battery when you have to.

It goes on hibernation mode, preserving the current state of RAM on the disk. Once there is enough charge, it will wake up normally.

I suspect they shutdown at a much higher level than that of the battery capacity. Somewhere around 20% of actually battery capacity, but is probably displaying near 0%.

Running these batteries to actual 0 is never a good idea. They may not be able to take a charge if you run them too far down. Lookup LiIon jump start.

FWIW, Tesla sets the safety limit for their LiIon cars to 20%. If they go below that they stop and cannot go again until recharged to a minimum level.

It's supposed to hit "zero" (which is actually a bit above true empty) and go into safe sleep, where memory will be preserved if it really does hit empty. If the battery calibration is off, or if the battery health is abnormal, it may not have time to write all the memory to disk before the battery really runs out, in which case it turns off from loss of power and you lose things.

Top off your battery and do not let it run down that much. I know this is not your question, but it's just a tip if you want to preserve its life for a long period of time.
