Regularly charging phones can harm battery health. This is why the battery backup often diminishes even after a full charge. The 80:20 rule helps maintain battery performance and extends the duration of optimal backup. Apart from the 80:20 rule, some other points should be considered during charging. Always use the original charger, and refrain from using the phone while it charges. This prevents the battery from degrading quickly and keeps charging speeds stable. Repeated full charges gradually degrade battery health. However, charging the phone between 20% and 80% reduces stress on the battery cells. This rule is particularly advantageous for users with fast charging capabilities. In the summer, many smartphones, especially iPhones, heat up while charging. To prevent this, Apple recommends charging only up to 80%. This rule eases the strain on the battery and reduces the problem of phone heating. The 80:20 rule is a simple, yet effective method of mobile charging. The rule suggests charging the phone when the battery drops to 20% and unplugging the charger when the battery reaches 80%. This protects the battery from overloading and ensures better performance over time.
