Do all flashlights slowly discharge when not in use? (kbin.social)

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.

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.
