Ideally, charge your phone between 20% and 80-90% to maximize battery lifespan.
Why This Range?
Multiple sources suggest this range as optimal for lithium-ion batteries, the type found in most modern smartphones. Charging to 100% regularly and letting the battery drain completely to 0% can both degrade the battery faster.
-
Lower Bound (20%): Letting your battery drop below 20% is detrimental. It stresses the battery and can shorten its lifespan.
-
Upper Bound (80-90%): Charging past 80-90% significantly reduces charging efficiency, especially with fast charging. Prolonged exposure to high charge levels also puts stress on the battery.
Several sources recommend maintaining a charge level between 30% and 80%, or even 40% and 80% for even better battery health. The best approach is to find a balance that suits your usage patterns. Aiming for the 20-80% or 20-90% range is a practical guideline.
Different Perspectives:
While the 20-80/90% range is widely recommended, some suggest a slightly different approach:
- Maintaining a 50-60% charge: Some sources suggest keeping the battery closer to 50% consistently to optimize its health. This is an alternative strategy, particularly if you use your phone intensively.
Practical Tips:
- Avoid extreme charging habits: Avoid letting your battery drain completely or consistently charging it to 100%.
- Utilize optimized charging: Many modern smartphones offer optimized charging features that adjust charging speed to prolong battery health. Enable this feature if available.
- Consider your usage: If you use your phone extensively, charging more frequently to maintain a higher percentage (e.g., 30%-80%) is preferable to letting it drain to 20% before recharging.
By following these guidelines, you can significantly extend the life of your phone's battery.
