Mi Portable Bluetooth Speaker cannot be turned off, please follow the steps below to troubleshoot:
1. The speaker may be dead. If the speaker does not turn off after pressing and holding the power button for more than 5 seconds (the indicator light is off and accompanied by the shutdown sound), you can try to reset the speaker (press and hold the power button for 12 seconds and then release it (when it is turned on or off) Long press is ok), the speaker reset is completed after the orange indicator light stays on for 1 second), the speaker will automatically restart after reset, if the speaker does not restart, please try to reset it several times;
2. If the speaker still cannot be turned off after resetting several times, please apply for after-sales testing.
