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

It'd be nice if the battery controller/charger had the intelligence to make these optimizations transparent to the end user. So present them with 100% or whatever, but in actuality, the battery is at 90%, most of the time it's plugged in, and so on.

I thought this was actually standard operating procedure for laptop batteries (or really, anything using lithium batteries). Similarly, 0% is actually more like 5 or 10%.

If you actually deep discharge a lithium battery to 0%, think they'll sometimes have problems taking a charge again. You see this occasionally when someone has taken to 0% on the meter, then let it self-discharge on the desk for a long time.

Yeah I thought so too. The parent comment seemed to indicate otherwise.
