    “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.

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

          From time to time you want to let the battery go from 100% to shutting off, so the charging circuit can calibrate the reported capacity
