What is the meaning for different indicator statuses of the Xiaomi Bluetooth Speaker?

For your reference, here is what the different indicator statuses mean below:
1. White: Power ON, voice alert, combo playback or normal power charging;
2. Blue: Bluetooth pairing, restore factory settings or system upgrades;
3. Orange: Low power alert or low power charging.
Note:
If no operation is performed or no audio is played on the speaker for 15 minutes, it will be turned off automatically. This function can be disabled or customized in the Mi Home/Xiaomi Home APP.
