I have a rooted phone with unofficial lineageos installed. It is my personal device. But I barely use it. If someone calls I pick up, that's about it. The phone is completely clean too, no trace of whatsapp or anything like that. The most bloated app on the phone is brave. Like I said, squeaky clean. Now I want to turn this into a machine using plain termux or chroot to run piefed, gotosocial and stuff, and host my blog page, but I am undecided. Since it's rooted, I thought I could set up something that starts charging at 45% and cuts off at 75%. What do you think I should do?

The main question is in the title. If you run a server on your own device, what do you host on it?
