What does the charging speed of the mobile phone relate to?
The charging speed of the mobile phone is generally influenced by three aspects.
1. the output power of the power adapter (charger) can meet the demand of the mobile phone. According to the different mobile phone battery capacity, charging current of the requirements are different, are generally 05C-0.8C, such as 2000MAH battery 0.5C, is the current 1A, 0.8C is 1.6A, his charge current at 1A to 1.6A, mobile phone will generally to this value for a set of 1A or 2A, but also to meet the power adapter on the market (charger) output standard. It is easy to understand that the charge current of the battery capacity less than 2500MAH is generally 1A, and the charging current of more than 2500MAH is 2A.
2. whether the voltage drop of the data line is qualified. The data line is connected to the charger and cell phone, because the data line has resistance, so it will produce voltage drop on the data line. If the resistance is too large, it will cause a lot of power loss on the data line. Effect of charging speed, the data line some of the street on the market inside the wire is very small (smaller resistance bigger), not even copper (e.g. copper clad aluminum), resistance value is very large, can lead you to charging slow, even not charge.
3. whether the charging mode has a current limiting. If you use the wrong way to charge the charge, you can also be restricted to the charging current, causing your power adapter power to be too powerful. The common limiter has two kinds, one is the data transmission mode of charging current, will be limited to less than 0.5A, common in the computer USB port for charging the mobile phone in the office crowd, the most simple method to solve this problem is the data line for a special charging line.
