"Fully empty your battery before charging it up again, it increases the lifespan of the battery."

This was true before lithium-ion batteries became the norm. But for lithium-ion batteries, the opposite holds.

    Remembering which of my devices are old method charging and which are new method is a pain.

    I have several camping lamps from like 20 years ago that I almost threw out because they weren't holding charge anymore, before I remembered to be fully draining the batteries and recharging them once a month. They work like new now practically.

    What's the opposite of "full empty your battery before charging it again?"

    Don't let it uncharge fully. You ideally want to stay in the 30-70% range as much as possible.
