Charging thresholds

[brammiddendorp]

To extend the battery life of devices running AsteroidOS, having the ability to set a charging threshold would be very helpful.
I'm not sure whether OpenEmbedded even allows this, as the procedure for it tends to differ from system to system.
On my laptop (Fedora) I could specify a maximum by changing the contens of /sys/class/power_supply/BAT0/charge_control_end_threshold. On my phone (SailfishOS) I was able to achieve this by running mcetool --set-charging-disable-limit=<desired percentage>.
I have inspected the various folders and files in the /sys folder, but could not find anything similar. mcetool also didn't recognize the option that was available on SailfishOS.
If it is at all possible with the current implementation, I'd be very glad to hear. If not, I think it would be a valuable addition.
