Yes, frequent partial charges can help prevent lithium-ion battery degradation. By maintaining a charge level between 20% and 80%, you reduce stress on the battery compared to full discharges and charges to 100%.
Key reasons:
- Reduced voltage stress: Every 0.10V reduction below the standard 4.20V/cell charge voltage roughly doubles cycle life, though it lowers usable capacity.
- Avoiding deep discharges: Partial discharges cause less wear than full cycles. Charging more frequently (e.g., at 50% state of charge) can increase lifespan by 44-130% in some cases.
- Temperature/current benefits: Partial charging limits exposure to high currents and heat, which accelerate degradation.
However, partial charging reduces immediate usable capacity, so balance this practice with occasional calibrations if runtime monitoring is critical. Modern devices are generally optimized for this charging behavior.
