Why does red rice 5puls always kill the background automatically?

This is because there are no settings that allow applications to run in the background. The setting method is as follows:

First click the "Settings" icon on the mobile phone desktop, as shown in the figure.

2. Then select the "Power and Performance" option in the setting interface of the mobile phone, as shown in the figure.

Third, then open "power saving optimization" to enter, as shown in the figure.

4. After entering, click Go Settings under "Application Smart Power Saving", as shown in the figure.

5. Then select the application that you want to set to allow running in the background. Take the drip behavior as an example, and click enter.

Sixth, finally check the "unlimited times" item, so that Didi Chuxing can always run in the background of the mobile phone.
