There are many reasons why the mobile phone is charging slowly. The smartphone is originally a mobile phone with relatively large power consumption. Even if it is not used very much, the software on the mobile phone will consume power. If the mobile phone is charging slowly, is it related to the data cable?
Inferior data lines are the "killers" to slow down the charging time. It is difficult for ordinary people to distinguish the difference between the data lines from the outside. Therefore, if all interfaces are consistent,mixing is something that happens often. However, the number of currents provided within different data lines may be different.
Many low-priced data lines look quite thick, but the inner core is very thin, or replaced by pure copper into the aluminum wire. In addition, the contact material and soldering of inferior data line connectors may have hidden dangers. The above problems will lead to an increase in resistance. The standard data line resistance should be 05 ohms, while the inferior line may reach 3 to 6 ohms, and the charging efficiency naturally decreases 6 to 12 times.
The charging specifications of the power adapter affect the charging speed. Most of the branded mobile phones are now equipped with a standard 5V charger, but manufacturers generally use different output currents depending on the battery capacity. When we charge the iPad with a charger with an iPhone with a maximum output current of only 1A and charge the iPad with a 2A original charger, the charging time of the former is 2.1 times that of the latter under theoretical conditions. 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 brand chargers whose current is not lower than the original standard.
