Is it better to let lithium batteries stay plugged in or constant 80/20 cycle (lemmy.world)

I am doing research on best practices for my lithium batteries and lifepo4 powerstation. There's some conflicting opinions and variation for cycle numbers.

Will leaving my things plugged in at 100% hurt it more than constantly unplugging at 80% and replugging at 20%?

Absolute best is keeping the battery plugged at 60%

Some phones have "store mode" that caps battery charge at this level and its used primarly by stores to keep one phone always plugged and turned on for display.

If you cant do that then 80 to 20 is second best thing. Keeping it at 100% is the worst.

This is about lithium ion batteries, no idea what best practices are for lifepo4
