When we were in the use of mobile phone charger for mobile phone, are often faced with charging sometimes fast, sometimes slow charging phenomenon, even with the electric power decline, and the charging indicator light is lit.So what is the causes of this phenomenon?And is there a link between cable?A lot of people should have such doubt, here are the charger manufacturers for you on cell phone speed related to whether the data line.
Cable is connected to the charger and mobile phone, because there is cable resistance, so the data line will produce pressure drop, if the resistance is too large, will cause a lot of power loss on the cable.Is will affect the charging rate, some of the side of the road on the market of the inside of the cable wire is very thin (the more the greater the resistance), and even not pure copper (copper clad aluminum, for example), resistance is very big, could lead to a slow to charge, even charge it into electricity.
To mobile phones internal charging, charging speed depends on the size of the current, the size of the load.Alternating current (ac), switching power supply, the resistance of the cable, cell phone charging circuit dc, battery protection board, batteries, these links are all affect the charging current.Among other issues, the wire diameter of the conductor material for current is very big, the influence of wire rod and wire, with poor itself is resistance, while the difference of wire will cause resistance increase, reduce by the current.Also caused the speed of mobile phone recharge reduced.
More important is the cause of the cable connector, basically flagship machine's own original charging line USES the wire is very good, the joint is different from place to place.Joint, tightness of pin, welding quality, the quality of the interface of the coating, these are all can cause resistance to become incentives to make the mobile phone charging speed slow.
To sum up, the speed of mobile phone charging and data line are related, and the relationship is very big, so we in the use of the charger to charge, had better use good quality head and charging cable for charging, so as to ensure both charging speed, and can ensure the safety of mobile phones and chargers.
