ThinkPad has this. My battery only charges to 75% and it must drop to 50% before it starts charging again. You can configure any value for either setting with TLP.

Is the screen dimming not a setting in your OS?

Dell has advanced power management options in the BIOS, I set it to keep the battery charged at 70%, which is ideal for lithium batteries. And you set a custom schedule on days you need the battery charged at 100% so that you can take the laptop with you at full capacity. It's not rocket science, and definitely something anybody reading this site should be able to figure out for their make/model. For MAC there is a similar app that resides in top system tray where you can also define max charge. (https://apphousekitchen.com/ )

The article's advice isn't the best. It's better to not cycle your battery whenever possible. Set your battery up to only charge when bellow a certain threshold (I do 70%) lower than the max charge (I have it set to 80%). This optimises for not over straining the battery (by not going to 100%) and it reducing cycles to a minimum for my everyday use only travelling between (desk) locations. I set this up through the p…

^this guy batteries.

but seriously, when they announced EV with lithium batteries, all I could think of was the baby sitting for batteries. Look at all the intelligence that goes into those EV car setups.
