The Mi 8 has pre-installed the fast charge function, but it needs to meet the following two conditions to normal use:
1. Use the original fast charger: Mi 8 needs to use the original fast charger that supports the QC 3.0 fast charging protocol, and the use of other brands of chargers may not be able to charge normally.
2. Enable the fast charge mode: When the phone is charging, press and hold the power button to enter the shutdown screen and select Fast Charge to enable the fast charge mode.
Note:
1. Fast charging mode hand will have a certain heat, this is a normal phenomenon.
2. Do not charge the mobile phone in a high temperature environment for a long time to avoid affecting the battery life.
3. Do not use inferior charger, so as not to damage the phone.
Is to support the default fast charge, plug in the original charger after you can go in fast charge
