Normally, charging a smartphone from zero to 90 percent can be very fast, but when the battery is charged above 90 percent, it does become extremely slow. This is because the charging of smartphones has a certain relationship with the protection of the battery.
The smartphone uses Smart Battery technology, which helps the battery to be better protected, and when the battery is charged to 99%, the smartphone will slow down the charging speed to protect the battery from overcharging, which can cause the battery to explode or shorten the life of the battery. Therefore, before charging to 100%, the smartphone will appropriately slow down the charging speed to protect the battery to work consistently and healthily.
Therefore, when you encounter this situation, don't worry too much, please wait patiently. Of course, if you have more questions about mobile phone charging, please feel free to contact us, we will do our best to help you.
The reason why the phone charges to 99 to 100 is so slow is because in the process, the phone charges gradually slower, which is to protect the battery and make smart slow down design.
When the battery power reaches about 90%, the charger will reduce the output current and voltage, so as to maintain the stable state of the battery and prevent overcharging and overheating. In addition, the smart charger also adjusts the output power according to the battery level and temperature, thus maximizing the battery life and protecting the phone circuit.
If you want to charge faster, you can use the original charger, make sure the charger is powerful enough, and avoid using the phone and charger at the same time.
When charging, try to put the phone in a place with air circulation to avoid overheating. These measures can help speed up recharging while protecting your phone's circuitry and battery life.
The speed of charging the phone to 99 to 100 is slow because the battery will automatically charge management when charging, to avoid battery damage due to long charging. When the battery is about to be full, the mobile phone will enter the \"full charge protection mode\
This is because the mobile phone battery in the process of charging, because the mobile phone to boot charging, some programs will run, when the mobile phone charging to more than 90%, the mobile phone will enter the intelligent charging adjustment mode, this time the
charging current is intelligent adjustment, to prevent overcharging to the mobile phone itself and the battery caused damage.
Usually, the charging speed of the mobile phone is relatively fast when the battery is low, and when the battery is quickly filled, in order to ensure the safety of the battery and extend the battery life, the charging current will gradually decrease, and the charging speed will slow down until it is full. Therefore, the charging efficiency of each stage of the mobile phone power is not exactly the same.
