-
Charging Speed: Fast charging generates more heat, which can accelerate battery degradation. The Institute of Electrical and Electronics Engineers (IEEE, 2020) found that charging at high voltages can lead to lithium plating, reducing the battery’s efficiency and ultimately decreasing its lifespan. Slower charging at lower voltages is gentler and better for the battery’s health.
-
Temperature: Battery performance is highly sensitive to temperature. A study by K. Takeuchi et al. (2019) indicated that charging batteries at elevated temperatures can reduce their lifespan by up to 50%. It is advisable to keep batteries within optimal temperature ranges to avoid thermal stress.
-
State of Charge (SoC): Keeping a battery at a high state of charge constantly can lead to premature aging. Research conducted by J. Zhang et al. (2021) showed that maintaining a charge level between 20% and 80% can significantly improve lithium-ion battery longevity. Full charges impose stress on the battery chemistry, leading to capacity decay.
-
Depth of Discharge (DoD): A deeper discharge can shorten a battery’s life. According to findings by M. Winter et al. (2016), frequent discharges below 20% can increase wear on the battery. Limiting discharges to shallower levels supports better longevity.
By understanding these factors and modifying charging habits accordingly, users can optimize battery performance and prolong the life of their devices.
