Why Your Android Phone Isn't Showing Notifications Even With Good Internet (Adaptive Battery Is Probably The Culprit)
I almost missed a really important call last month because my phone just... didn't buzz. No notification, nothing. My WiFi was working, my mobile data was fine, and I later found out even the Google push connection was working perfectly. So what was going on? Turns out the villain here wasn't my internet. It was a setting sitting quietly on my phone the entire time, doing exactly what Google…
I experienced a missed important call last month due to my phone not buzzing. Although my WiFi and mobile data were functioning properly, I later discovered that Google push connection was also working fine. This led me to investigate the cause and found that the culprit was a setting on my phone, called Adaptive Battery, designed by Google to save battery life by aggressively killing apps.
Named Adaptive Battery, if you're on Android 17, it may be responsible for ruining your notifications as well. The problem is that notifications reach your phone through Google's FCM servers (Firebase Cloud Messaging), the system almost every app uses to send you notifications. However, Adaptive Battery decides which apps are important enough to run in the background.
If an app is deemed low priority, it gets killed or restricted so much that even an incoming push notification cannot wake it up properly. Many apps, including WhatsApp, Signal, Telegram, Gmail, Messenger, Slack, and Discord, can be affected by this. The issue is particularly noticeable on Pixel devices, which receive the update first.
Adaptive Battery aims to extend battery life by limiting background activity for less frequently used or deemed unnecessary apps. However, it often misjudges which apps require real-time alerts, and messaging apps are frequently caught in the crossfire. Turning off Adaptive Battery is straightforward: go to Settings > Battery > Battery Saver or Adaptive Preferences > Adaptive Battery, and toggle the switch to the Off position.
This may result in a slight decrease in battery life, but the trade-off is worth it for many users who cannot afford to miss critical calls, messages, or alerts.
