Modern group chats, live sports updates, social media notifications, and gaming apps often fire off a barrage of rapid-fire alerts within seconds. Listening to your phone buzz and chime twenty times in a single minute while a family member posts multiple lines of text creates severe notification fatigue and workplace distraction. Rather than permanently silencing apps or manually enabling Do Not Disturb, Android 15 introduces an intelligent, native system feature called Notification Cooling. This feature automatically detects alert spikes from individual applications and progressively dials down the notification volume and vibration intensity for subsequent messages.
How Notification Cooling Operates
Notification Cooling introduces adaptive rate-limiting algorithms to the Android notification manager:
- Progressive Volume Attenuation: The first notification from an app arrives at your full chosen volume and vibration intensity. If the same app posts subsequent notifications within a few seconds, the audio chime is gradually lowered with each successive ping.
- Vibration Suppression: Along with audio volume reductions, physical haptic motor vibration is scaled down, preventing your phone from skittering across desks during intense group messaging chatter.
- Critical Alerts Bypass: Emergency alerts, direct alarms, scheduled reminders, and prioritized VIP contacts (calls from starred family members) bypass Notification Cooling completely, ensuring urgent communications are never obscured.
- Reset Threshold: Once the flood of messages ceases for a brief pause (typically 15 to 30 seconds), the volume ceiling automatically resets, ensuring the next standalone message arrives at standard audible volume.
Prerequisites and Android Version Compatibility
Notification Cooling is a core platform feature introduced in Android 15 (Vanilla Ice Cream):
- Supported Handsets: Google Pixel (Pixel 6, 7, 8, 9 series and Pixel Fold/Tablet) running the official Android 15 release, alongside eligible devices from Samsung (One UI 7), Motorola, OnePlus, and Xiaomi updating to Android 15.
- System Software: Ensure your device has updated to the latest security patch via Settings > System > Software update.
Step-by-Step: Enabling Notification Cooling
Follow these steps to activate Notification Cooling on your Android 15 smartphone or tablet:
- Open the Settings app from your app drawer or home screen.
- Scroll down and tap Notifications.
- Scroll through the notification settings to locate Notification cooling.
- Tap on Notification cooling to open its configuration panel.
- Toggle the feature switch to the On position.
Choosing Between Cooling Presets
Android 15 allows you to select how broad you want the cooling behaviour to apply across your app ecosystem:
- Apply cooling to all notifications: Extends progressive volume reduction across all applications installed on your phone, including social feeds, news apps, work messengers (like Slack or Teams), and shopping notifications.
- Apply cooling to conversations: Restricts the cooling algorithm specifically to messaging apps and group chat threads (such as WhatsApp, Telegram, Google Messages, and Signal) while keeping standalone app updates at their normal alert volume.
Customising Channel Importance to Prevent Unwanted Cooling
If you have specific high-priority alerts within an app (such as server outage alerts or delivery driver updates) that must never be dimmed, you can adjust the notification channel’s priority:
- Go to Settings > Apps > See all apps.
- Select the target application (for example, your home security or monitoring app).
- Tap Notifications, then tap the specific Notification Category / Channel (e.g., Critical Alerts).
- Ensure the channel importance is set to High or Urgent, and enable Bypass Do Not Disturb if applicable. High-priority system channels are prioritized above the cooling threshold.
Comparing Notification Cooling to Do Not Disturb and Snoozing
Understanding where Notification Cooling fits within Android’s notification toolkit helps streamline device ergonomics:
- Do Not Disturb (DND): Completely silences all non-exempt notifications. Best for sleeping, focused deep work, or meetings where zero audible interruptions are tolerated.
- Notification Snoozing: Temporarily dismisses a specific alert to reappear 15, 30, or 60 minutes later. Ideal for tasks you cannot attend to immediately.
- Notification Cooling: Dynamically tames alert storms in real time without muting the app completely or requiring manual intervention. You never miss the initial message, but you avoid being overwhelmed by subsequent chatter.
