Because in the process of using the mobile phone, the battery will gradually decay and the health will decline. This is an irreversible normal phenomenon, and its health status cannot be improved by scientific methods. If the health of the battery is low and affects its use, the only way is to replace the battery. The new battery will show 100% battery health, which will gradually decrease with the extension of service time.
Correct charging method:
1. Avoid using the mobile phone while charging.
Many friends like to play games or brush videos while charging, which will greatly consume battery efficiency. Because the mobile phone is supplying power while using electricity, the temperature will rise more easily, which will increase the burden on the battery. If you send a message to browse the web, the impact will not be great, but if you play games, watch videos or make phone calls, you will really try to avoid it.
2. Try to avoid using fast charge.
At present, the iphone supports fast charging up to 20W, but fast charging means that the temperature of the mobile phone will be higher, which is very unfavorable to battery health. The best charger should choose 5W official charger, which is slower but best for the battery.
3. Turn on and optimize battery charging.
When this function is turned on, the mobile phone will learn the daily charging time by itself. For example, many people are used to charging their mobile phones all night when they sleep at night. If the charging function is optimized, they will remember this time interval. After charging to 80%, they will slow down the charging speed and lengthen the charging time to keep the battery at a suitable temperature. This function can greatly protect the health of the battery, so be sure to turn it on.
