Some people find that after using the mobile phone for a period of time, the cell phone battery power of the mobile phone will drop very fast. Sometimes the charging of the mobile phone is getting slower and slower. Before charging is very fast, why is it getting slower and slower now? This is because many users do not develop good habits when using mobile phones. What factors will affect the charging speed of mobile phones?
Mobile phone charging protocol
The phone itself supports fast charging, which is the charging protocol for mobile phones. Of course, Power Delivery is the best agreement. But the agreement itself is not important, the focus is on power. First determine what agreement is on his mobile phone. Most of the current is below 2A, and the data cable can be as long as it is not a poor quality product.
A good data line must be equipped. The fake data line not only has an impact on speed, but also has security risks. The data cable is connected to the charger and the mobile phone. Because the data line has resistance, there will be a voltage drop on the data line. If the resistance is too large, the power will be lost to the data line. The speed of the mobile phone charging and the data line are Great relationship.
The adapter that matches the phone’s charging protocol will get the best charging speed. Whether the output power of the power adapter can meet the needs of the mobile phone. According to the different battery capacity, the charging current requirements are different, generally 05C-0.8C, for example, 05C of 2000mAH battery, the current is 1A, 0.8C is 1.6A, and his charging current is 1A to 1.6A. In the meantime, the mobile phone generally sets a value for this value, 1A or 2A, to meet the output standard of the power adapter (charger) on the market.
Good power supply environment
The charging environment is also very important for the charging speed. In a low temperature environment, the low temperature protection mechanism of the lithium battery will cause the battery activity to decrease, causing the charging speed to slow down or even not charging. It is best to charge your phone at room temperature. The mobile phone interface will not be cleaned for a long time, and dust may cause poor contact between the charging port and the data cable.
