Question:

Why am I not receiving message notifications immediately but they occur when I open the messaging app?

Answer:

It seems that the issue might be related to the Adaptive Battery feature on your device. This feature learns your usage patterns for different apps and prioritizes their performance to optimize battery life. As a result, apps that you don't use frequently may be restricted in the background, causing delays in receiving notifications.

To fix this, you can add the messaging app to the list of "Never sleeping" apps on your device. Here's how:

Go to Settings.

Tap on Battery and Device Care.

Select Battery.

Scroll down and tap on Background Usage Limits.

Click on Add Apps and select your messaging app.

Confirm the selection to whitelist the app and prevent it from entering sleep mode.

By doing this, your messaging app should now be able to function properly in the background, ensuring that you receive timely notifications without any delay.
