App "Notifications" are Delayed by Hours

4.5

You get a WhatsApp message at 2 PM, but the notification only pops up at 5 PM.

Symptoms
  • Late alerts
  • Batch notifications
  • Sync lag
Possible Causes
  • Aggressive battery saving
  • "Doze" mode (Android)
  • Unstable background data

Step-by-Step Fix

1

Disable Battery Optimization

Settings > Apps > [App] > Battery > Set to "Unrestricted".

2

Enable "Background Data"

Ensure the app can use data even when you aren't looking at it.

3

Disable "Adaptive Battery"

System-wide setting that can delay low-priority notifications.

When to See a Technician

Modern phones "kill" background apps to save battery; if an app is killed, it can't tell you about new messages.
