You can't receive information without opening WeChat.

The reasons why you can't receive information without opening WeChat are: clearing WeChat when clearing memory, setting application intelligence to save power, and turning off WeChat notification.

1. Clean up WeChat when cleaning up memory.

The operation of cleaning up the background directly cleans up the WeChat background, and there will be cases where WeChat cannot receive messages in the background.

Solution: Long press WeChat in the background interface, and a small lock icon will appear on the left to lock WeChat, so that WeChat will not be cleaned up in the background.

2. Set the application Energy Smart.

Once this switch is turned on, the mobile phone will automatically end the application process when the application is not running, thus saving the power of the mobile phone and improving the battery life.

Solution: Open the settings, then go down to find the power saving and battery, enter the battery settings header, slide down, find the switch for applying intelligent power saving, click the switch, find WeChat in it, click Open, and change it to unlimited.

3. Turn off the WeChat notification.

Many times, we can't receive notifications and reminders from WeChat in the background. Many times it is because we have closed the notification authority of WeChat.

Solution: Turn on the switch of permission notification.

Wechat has started:

If you set the permission to allow WeChat notifications, you can automatically start WeChat in the background by setting the self-start permission to open WeChat, so that you can receive new message reminders without opening WeChat.

Wechat belongs to a third-party APP, and any permissions it uses must be authorized by the system. The "self-start" permission is to control whether WeChat can automatically start running and keep running in the background. If this permission is turned off, a WeChat screen will appear every time the user opens WeChat, and the system will automatically empty WeChat, so it is impossible to receive real-time messages. Only by reopening WeChat can you receive messages normally.
