Is there a delay in receiving messages on Apple WeChat? Check if the iPhone's low data mode is turned on

In order to help users control data consumption, Apple has added a new feature "Low Data Mode" to the "Cellular Mobile Network" and "Wi-Fi" of the iOS 13 system.

After turning on "Low Data Mode", iPhone will reduce mobile data usage by postponing the refresh of inactive tasks and disabling background application refreshes, which can greatly save traffic.

However, turning on this feature may also cause delays in receiving app notifications!

If your WeChat or other communication apps experience a delay in receiving messages, you can modify it as follows

1 Open the "Settings" app, select "Cellular Network" - "Cellular Data Options" (dual SIM users select their own Internet number) - turn off "Low Data Mode"

2 Turn on "Wi-Fi" again, click the "i" button after the name of the connected Wi-Fi, and turn off "Low Data Mode".
