1. Battery aging problem.
The battery of the general mobile phone is more prone to various problems after 2-3 years of use. For example, battery life decreases, the phenomenon of oxidation of battery contacts leads to incomplete contact, which will accelerate the aging of the battery, thus affecting the charging speed of the mobile phone. If the contact is oxidized, you can go to the mobile phone repair shop to find someone to help remove the oxide layer.
2. Mobile phone charging port problem.
Due to the personal use of the environment, resulting in dust into the charging interface, which will affect the speed of charging. Usually we put the mobile phone in the pocket of the pants, do not pay attention to the charging port down, it is easy to let the charging interface of the mobile phone into the ash. After the dust enters the mobile phone, it is easy to block the charging port, resulting in poor charging contact, which will make the mobile phone charge slowly.
3. Charging interface problem.
After the mobile phone charging port is used for a long time, there will be problems such as poor contact in the later stage. Daily charging requires special care to avoid the appearance of slow charging or inability to charge at the beginning due to loose interfaces in the middle.
4, the charger specifications.
Now almost all mobile phones are with fast charging function, if you use the charger is not comfortable, then it will affect the speed of mobile phone charging. Now the chargers on the market are generally 5v, fast charge is 9v, and super fast charge is 11v. So to a large extent, the charger will directly affect the speed of charging. For example, the original charger of your mobile phone originally output the standard current of 1A, if you use other chargers with a standard configuration of less than 1A to charge your mobile phone, it will naturally be slower. Therefore, when charging the mobile phone, in order to ensure that the charging speed of the mobile phone is fast enough, you should try to choose the original charger or other brands of chargers whose output current is not lower than the original standard.
5. Charging cable problem.
Aging, unqualified, length, and so on, will affect the quality of charging. The charging line will have poor contact for a long time, causing the charging current to be too small, so that the charging becomes slow, which can be solved only by changing a new charging line. It is difficult for ordinary people to distinguish the difference between the data lines from the appearance, so all interfaces are consistent, and mixing is like routine, but the number of currents provided by different data lines may be different. Poor quality charging cable also affects the speed of charging. The quality of the charging cable is uneven, the surface is not visible, but the internal wire core is very thin, or the pure copper has been replaced by aluminum. In addition, the contact material and welding quality of the inferior charging cable connector may have hidden dangers, and the above problems will cause the resistance of the charging line to increase. The standard charging line resistance should be 0.5 ohms, while the inferior charging line may reach 3 ~ 6 ohms, and the charging efficiency naturally decreases.
