Does Discharging Battery Completely Before Recharging It Again Improves Battery Life?

The video tutorial explains that fully discharging lithium ion batteries before recharging does not extend their life and can actually harm them. Unlike older nickel-based batteries, lithium ion batteries do not suffer from the memory effect. They are designed to retain at least 80% capacity for 300 to 500 cycles. To maintain battery health, it is recommended to keep the charge between 20% and 80%. Fully draining or charging to 100% can lead to faster degradation. The 80-20 rule is suggested for optimal battery longevity.
