Ask HN: Should I unplug my laptop charger at 100%?

#32AFAIK only macbooks have been designed to bypass battery ( once the charge is 100% ) and directly run on connected power. For other notebooks its best to unplug charger at 100% and connect charger at around 10% to get a longer lifetime of the battery.
Not 10%! That's terrible for a Lithium battery. Charge it when it gets to 40%.

#35You could remove the battery when its charged and stay on the cord. Because battery life is heat-related. And leaving a charged battery in the laptop when you have a cord is chewing up lifetime without benefit.

If you never observe a zero (or, presumably, a 100%), it might recalibrate incorrectly. Again, this is based on old and uncited knowledge. There's surely someone here involved in writing power management software that could chime in.

#39Bad UX. One shouldn't have to worry about this!

#40when i called apple to replace the battery on warranty because it had started to bulge/swell dangerously and not hold charge, they had me open up the system information panel to see how many cycles it had been through, and it was hilariously low, like, 4. they refused to warranty it.
so at the very least, if you care at all about your warranty coverage, you should probably cycle it normally.
