ArchWiki: Hibernate on low battery level

This approach uses udev, so you don’t have to constantly check the battery level by yourself.

Try to reduce your commute time. Ideally, switch to a job where you can work from home. Try to reduce your fixed costs as much as possible. Consume as little as possible. Become as self-sufficient as possible, so you are less dependent, which in turn reduces the pressure.
