The fast charging function of Xiaomi mobile phone suddenly became an ordinary charging form, which is because the charging device has changed or the fast charging mode has been artificially closed. If you need to open the fast charge mode of Xiaomi mobile phone, the specific method is:
Step 1: Open your phone's Settings.
Step 2: Find more Settings and click.
Step 3: Find the dual engine flash charge and turn it on, and charge it with the original charger.
In this case, you can unplug your charger and then reinsert it, or plug the charging head in reverse. If you really can't, I suggest you restart the phone again, thank you.
Is the mobile phone into the water, after the water will lead to damage to the internal components.
