I have a Thinkpad E495 that has Battery Charge threshold support. i.e. it can be set such that the battery starts charging at a specified amount of charge (say, 70%) and automatically stops charging at a specified charge (say, 80%). This feature is also available on Linux by using TLP (made by linrunner, his website is linrunner.de)
The problem is, I searched for this option in OpenBSD, but I couldn't find it. It is a very crucial functionality for me. So, if somebody can please tell me where I can set it, I would be very very thankful. (Pardon my bad english, it's not my first language)
