What is it that I can't receive information without opening WeChat?

The reason for this situation is to close the WeChat application or exit the WeChat account, or even completely close the mobile data and WiFi connection of the mobile phone.

The information received by WeChat does not depend on whether the WeChat application is open or not. Under normal circumstances, as long as the mobile phone network is unblocked (including mobile data or WiFi) and WeChat runs in the background (that is, WeChat is not completely closed on the mobile phone, but only returns to the background), WeChat information can be received.

In addition, if the mobile phone is set to energy-saving mode, it will prevent the background application from refreshing after the screen is closed for a period of time, and it will also lead to the inability to receive new message pushes in real time when WeChat is not open.
