I was thinking about buying a wurkkos fc11 as my first flashlight but it said they recommend untwisting it in a review to avoid making a connection so it doesn’t discharge while not in use. Do I need to worry about that with all flashlights? I was planning on keeping it in my backpack so I have it whenever.

    Good tip, but the OP should be aware that when at 3.7V they have only ~50% charge in them, so remember to also pack a spare or two (at the same voltage) to have the same total runtime.

      Should be closer to 60% but still, it’s not in a long term ready state. Long stored batteries should be recharged before use.

      In general, recharging them before use is better - if you’re preserving battery life as much as possible the ideal profile is to charge them to ~4.1V, use until ~3.5, then store at 3.6-3.7 until charged for next use, ideally minimising time sitting at full. Going below 3.4ish takes progressively more out of the battery life.
