Battery charge thresholds #4

Open speccy48 opened 3 years ago

speccy48 commented 3 years ago

Hi,

I got x2100 recently and 9-cell battery, and thanks to your patch it reports the battery readings correctly which is great. However, if I unplug it for 10 mins and then plug it back, it starts charging battery from 95% back to 100% which, as far as I understand, is suboptimal for battery longevity.

tlp I use to set it on other ThinkPads does not work here (as expected).

So it would be awesome if one could set battery charge thresholds, e.g. "start charging when battery is below 50%, stop when battery reaches 85%" to limit the battery degradation. Even a static version e.g. ec.bin that has fixed limits, would be great!

It's definitely possible. Not all that terrible to make it configurable at runtime. But I probably don't have the time to actually do it...
