Redmi note8 rings every half hour. What happened?

The reason why Redmi note8 E8 rings every half hour is to check the battery power, turn off the power saving mode and turn off the timer.

1, check the battery power: first, you need to check whether the battery power of the mobile phone is enough. If the battery is too low, the phone will go into power saving mode and ring every half hour. You can check the power status by pulling down the status bar, or go to Settings-Battery to check the power percentage.

2. Turn off the power-saving mode: The mobile phone has entered the power-saving mode, so you can try to turn off the power-saving mode. You can enter the setting-battery-power saving mode, turn off the power saving mode, or adjust the settings of the power saving mode to cancel the settings that affect the ringtone.

3. Turn off the timer reminder: The mobile phone has not entered the power saving mode, but the system has set the timer reminder function. You can go to Settings-Applications and Notifications-Clock to see if you have set a timer. You can turn it off or adjust the corresponding settings.
