Charging your battery to 90% is generally a good practice for extending its lifespan. This recommendation is based on the principle of avoiding both completely depleting and fully charging the battery.
Optimal Battery Charging Habits
The ideal range for maintaining your battery's health is between 30% and 90%. Keeping your battery within this range minimizes the stress placed on the battery's chemical components.
-
Why 90%? Reaching 100% charge and staying there for extended periods puts unnecessary stress on the battery. This contributes to faster degradation and a shorter overall lifespan. Charging to 90% mitigates this risk.
-
Why not less than 30%? Frequently letting your battery dip below 30% can also cause damage and reduce its longevity. While occasional drops below this level are fine, consistently keeping it in this low range is detrimental.
Practical Application and Benefits
By charging to 90%, you can:
- Extend battery life: Reducing the time spent at full charge significantly slows the degradation process.
- Maintain performance: A healthier battery translates to better and more consistent performance over time.
- Reduce charging cycles: Fewer full charge cycles mean less wear and tear on the battery.
The provided reference supports this approach: "The golden rule is to keep your battery topped up somewhere between 30% and 90% most of the time. Top it up when it drops below 50%, but unplug it before it hits 100%."
