Do mobile phone need to be fully charged?

Article Source：Kinri Energy | Author：Kinri Energy | Issuing Time：2024.03.13
No need, 80-90% is sufficient, leave some room for improvement! In our daily lives, mobile phones have become an indispensable part. To ensure that our phones can serve us anytime, anywhere, we often charge them. But you know what? Incorrect charging methods may have a negative impact on the battery life of mobile phones. So, how to properly charge your phone and extend the battery life?


1. In those years, we went through the charging misconceptions

Many people habitually charge their phones to 100% before unplugging them. They believe this is the best protection for the battery. But in fact, this approach is not scientific. The charging principle of lithium batteries is different from that of older batteries in the past, and overcharging can actually shorten the battery's lifespan.

(1) Overcharging can cause the electrolyte inside the battery to decompose, forming needle shaped crystals on the positive electrode. These crystals may puncture the battery separator, causing dangerous situations such as short circuits, fires, or explosions.

(2) Overcharging generates high temperatures, and in high-temperature environments, the electrolyte of the battery will accelerate volatilization, increasing the risk of battery deformation and leakage.

(3) Frequently charging to 100% battery capacity will accelerate the deformation of the battery grid, thereby shortening the battery life.

2. Charge correctly, starting from the basics

(1) Don't overcharge: When the phone's battery reaches 80% -90%, it's time to unplug the charger, let alone charge overnight. Apple's original batteries and chargers have also experienced explosions.

(2) Timely "recharge": When the phone's battery level is below 20%, please charge it in a timely manner to avoid running out of battery. Generally, mobile phones have a low battery alarm, which is the self-protection function of the phone battery.

(3) Don't use it while charging: Many people like to use their phones while charging, which can increase phone heat and affect battery life. For the happiness of batteries, please stay away from your phone while charging.

(4) Priority original accessories: Choose original chargers and data cables to charge your phone. Non original accessories may cause safety hazards and battery life loss.

(5) Regular battery health check: Over time, the performance of the battery will gradually decline. Regularly check the health status of the battery, and replace it promptly if there are any problems.

3. "small actions" to delay battery life

(1) Avoid frequent charging and discharging: Frequent charging and discharging can cause deformation of the battery grid and shorten its lifespan. So, the key is to use your phone reasonably and avoid frequent charging and discharging.

(2) Leave room for error: It is a good habit to keep your phone's battery level between 20% and 80%. This is beneficial for extending the battery life. When the battery level is below 20%, charge it in a timely manner; When the battery level exceeds 80%, the charger can be unplugged.

(3) Avoid prolonged use at extreme temperatures: both high and low temperatures can have a negative impact on the battery. In high-temperature environments, the automatic adjustment function of the phone can be turned off; In low-temperature environments, you can keep your phone warm in your pocket.

(4) Close useless applications and services: When using your phone, the system defaults to opening many applications and services. These programs and services consume a large amount of electricity. To save power and extend battery life, it is recommended to regularly close useless applications and services.

(5) Regularly cleaning phone memory and cache: The phone's memory and cache can accumulate a lot of junk files and useless data. These junk files and data not only occupy storage space, but also consume electricity. Regularly clean your phone's memory and cache to maintain optimal performance and extend battery life.

Proper charging is the key to extending the battery life of mobile phones, and mastering these tips can also help us better take care of the phone's lifespan.
