What causes a cell phone to charge fast or slow? How about fast charging?

July 19, 2024

1,the impact of the charger: the power of the charger determines the charging speed. It is best to use the original or officially certified fast charger, which can provide higher power and thus achieve faster charging speed. Poor contact of the charging port also tends to affect the charging speed. Because the interface of the phone or charger is exposed, it is easy to enter some dust and other small foreign objects, or due to external influences caused by wear and tear deformation, etc., will cause poor contact when charging, and in serious cases, even hot and lead to the phone can not be charged or charging intermittently, affecting the battery life.

2, the impact of the cell phone battery: different models of cell phone battery capacity and charging technology will also affect the charging speed. Some high-end cell phones use fast charging technology, such as USB PD (power delivery) or QC (quick charge), these technologies can provide high current in a short time.

3, the impact of the charging cable: high-quality charging cable also helps to improve the charging speed. It is recommended to use a cable that supports fast charging and make sure the cable is not damaged. The size of the current supported by different charging cables is also different, you can try the data line of others, the charging speed is normal after changing the line, that means changing the data line. It is best to use the original charging cable, in addition, in order to prevent the socket damage caused by the charging status is not normal, you can also change a power outlet to try.

4, the impact of the state of the phone: If the remaining battery power of the phone is relatively low, or battery aging, the charging speed may also become slower. In addition, opening the screen, using wifi, bluetooth, etc. will also consume power, affecting the efficiency of charging.

5, the impact of system settings: some phones allow users to adjust the charging strategy, such as "super fast charging" mode. Close unnecessary background applications and services can also improve the charging speed.

6, the impact of the ambient temperature: in the appropriate temperature (generally recommended between 0-45 ℃) charging, battery performance will be better, charging speed will be faster. Too high or too low temperature may affect the battery life and charging speed. And due to the characteristics of the lithium battery itself, it is sensitive to temperature, when charging, the temperature is too high or too low, it will damage the service life of the battery. Including today's cell phone charging will have a temperature protection mechanism, when the temperature is detected to be outside or below the normal range of use will reduce the charging current, and in serious cases, it will automatically cut off the power to stop charging.

To charge quickly, you can try the following methods:

1, the use of fast charging equipment: if the phone supports fast charging, try to use the matching fast charger and cable.

2, turn off the phone: when charging, try to turn off the phone screen and other background applications to reduce power consumption.

3、Optimize system settings: Enable fast charging mode when charging.

Avoid high-temperature environments: Place your phone in a ventilated area and avoid direct sunlight for charging.

5, regular maintenance: regularly clean the phone battery and charging port to ensure good contact, pay special attention to waterproof and dustproof.

It is worth noting that over-frequent fast charging may dislike the battery life, so in daily use, it is recommended to charge according to the actual needs, rather than the pursuit of fast.
