What is the 80-20 charging rule? The 80-20 rule means that you shouldn't let your phone's battery completely drain or charge it to 100 percent. According to this rule, you should start charging your phone when the battery reaches around 20 percent. Similarly, you should unplug the charger as soon as the battery reaches 80 percent. Doing this reduces stress on the battery cells and prevents them from degrading quickly.

Why is the habit of fully charging harmful? Users often develop the habit of charging their phones from 0 to 100 percent. According to experts, this can be harmful to the battery. Full charging puts more pressure on the battery cells, which rapidly reduces their chemical lifespan. This is why, after a few months, the phone's battery life starts to decrease, even if the phone is new.

Impact on battery backup and performance: Following the 80-20 rule helps maintain the battery's overall performance for a longer period. When the battery is under less load, it degrades more slowly. The direct benefit of this is that the phone's battery life remains stable for a longer time. This rule is considered even more beneficial for users who use fast charging.

It also helps with heating problems: In summer, phone heating during charging is a common problem, especially for iPhone users. The battery heats up more when charged to 100 percent. This is why Apple itself recommends charging only up to 80 percent. Adopting the 80-20 rule reduces pressure on the battery, and the phone's heating problem is significantly reduced.

What to keep in mind during charging:  Besides the 80-20 rule, it's also important to keep some basic things in mind during charging. Always use an original or certified charger to ensure the battery receives the correct power. Avoid using your phone excessively while charging, as this increases heat. By adopting proper charging habits, you can keep your smartphone's battery healthy for a longer time.
