There is no user setting change, you can change the charger internal circuit, but the cost is too high, complex and dangerous; The simplest way is to use a conventional charger with a rated output voltage of only 5v, you can turn the fast charge into a normal charge. Because the fast charging charger generally has three output voltages, such as 5v, 9v and 12v, only when the output voltage is 9v and 12v, and the fast charging protocol is matched, the fast charging function can be realized, so if the mobile phone with the fast charging function is charged with the ordinary charger, it is the normal charging.
The fast charging system consists of three major parts, the fast charging head, the fast charging data cable and the digital equipment supporting fast charging, each of which is a participant in the fast charging system. First of all, digital products need to support fast charging, and the second must be used to support fast charging protocol charging head and data cable, if the use of general charging head or data cable, the original fast charging will become ordinary charging.
A, the current is constant and the voltage is increased: under the condition that the ordinary charger current is maintained at 1A, the 220V voltage is reduced to the 5V charger voltage, and the 5V charger voltage is then reduced to 4.2V battery voltage.
When the voltage is increased to 9V, the charging time can theoretically be compressed to 50%, since this can only be changed in the phone voltage, design and production with this function, we personally can not change the normal charging
1. Confirm whether the original charger is used; Including charger plug and data cable;

2. Some mobile phones have a fast charge switch, which needs to be turned on in the setting;
< br >
3. Check whether the system has a new version, and then upgrade the system.
< br >
4. If it doesn't work, back up important data (contacts, text messages, photos, etc.) and try to restore factory Settings.

5. If the problem persists, please take the purchase invoice, repair card and machine to the service center for inspection.
When the mobile phone recognizes that the charging current meets the fast charging conditions, it will automatically execute the fast charging mode. If you want to use the ordinary charging mode, try to use the low-power charging head or use the USB2.0 port of the computer to charge, because the power supply current of the USB2.0 port cannot meet the current size of the fast charging. The phone will display normal charging mode.

Fast charging does not damage the battery, there is no need to artificially use the normal charging mode.
If you want to become normal charging with fast charging, you are advised to buy an ordinary charger, which is a normal charger, so that it is normal.
There is also the charger can be changed into an ordinary charger, this is the only way, if you want to fast charger into normal charging, then you have to set directly in the phone, do not allow him to fast charge.
