Is it bad to charge a phone with a 100W charger?

The Effects of Fast-Charging on Phone Battery Longevity

Advancements in charging technology have introduced high-powered chargers, such as those with a 100W output. While convenient, these chargers come with potential drawbacks for phone battery longevity.

Degraded Battery Health

Studies have demonstrated that using a 100W charger can significantly reduce battery capacity compared to slower chargers. A 100W charger can degrade battery capacity by 20% more than a 30W charger. This difference is particularly pronounced in devices with typical battery capacities of 3,500-4,000mAh.

Reasons for Degradation

Fast-charging involves supplying a higher current to the battery, leading to increased heat generation. Excessive heat can damage the battery’s chemical components, reducing its storage capacity and overall lifespan.

Impact on Battery Cycle Life

Battery capacity is directly linked to its cycle life, which refers to the number of times a battery can be fully charged and discharged. Using a 100W charger can reduce battery cycle life by approximately 20% compared to a 30W charger. Consequently, phones charged with 100W chargers may need to be replaced sooner due to decreased battery performance.

Recommendations for Extending Battery Life

To preserve battery longevity, consider adopting the following practices:

• Use lower-wattage chargers (e.g., 30W or 18W).
• Avoid charging your phone overnight.
• Keep your phone cool during charging.
• Enable optimized battery charging features in your phone settings.
• Calibrate your battery periodically.

Conclusion

While fast-charging with a 100W charger offers convenience, it comes at a price in terms of reduced battery health and lifespan. To extend the longevity of your phone’s battery, opt for slower chargers and adopt battery-saving practices. By doing so, you can ensure optimal performance and avoid premature battery failure.
