Is the data line bad for the phone?
, And even charge into the power.
Affect the charging speed, the market some of the roadside data lines inside the copper wire is very fine (the greater the resistance the greater the resistance), not even pure copper (such as copper clad aluminum), a great resistance, may lead to slow charging
Data lines are connected to the charger and the phone, because the data line resistance, so the data line will produce a pressure drop, if the resistance is too large, will lead to a large number of power loss in the data line.
This voltage drop, the phone to determine the voltage drop after severe, will automatically reduce the charging current.
Data lines on the charging speed of a great impact, because the poor data lines, the line is too thin, the material is not good, resulting in too much resistance, so there is a large line loss.
