Every device’s battery comes with an estimated recharge or battery cycle lifespan. This is the number of times that the battery can be charged back up before the charge capacity starts to diminish (down to 80% or lower.) The thought that you can extend this lifecycle by not ever running the battery all the way to 0 is indeed a myth. Li-Ion batteries do not care how low they get before a charge, they count a cycle every time you charge your device (whether that’s at 68% or 4%.)
Full vs. Partial Discharge.
Truth is, it doesn’t matter. Li-Ion batteries only care about recharge cycles – not how much energy is left. You may be thinking about older NiCad batteries and Lead-acid batteries that were temperamental, not wanting to recharge from empty or taking a very long time to recharge.
