What notification grouping does

Notification grouping is a feature that stacks similar notifications together instead of showing each one separately on your lock screen or notification panel. When you have multiple messages from the same app or person, your phone collapses them into a single expandable group rather than filling your screen with individual alerts.

For example, if you receive five text messages from a friend over the course of an hour, grouping shows you one notification that says "5 messages from Sarah" instead of five separate notifications. Tap it to expand and see all five messages at once. The same applies to email, social media, news apps, or any other app sending repeated alerts.

Grouping is on by default on most Android phones and iPhones, though the exact behavior varies slightly between devices and operating systems. The goal is to reduce notification clutter and let you focus on what matters without your screen being overwhelmed by alerts.

Key Takeaways

  • Notification grouping automatically stacks similar alerts from the same app or sender into one expandable group instead of showing them individually.
  • You can usually turn grouping on or off per app in your phone's notification settings, giving you control over which apps use this feature.
  • Grouped notifications still send you an alert sound or vibration for each new message, so you do not miss incoming information.
  • On Android, grouping is managed through individual app settings; on iPhone, it is controlled through the Notification Grouping option in Settings.

How grouping works on Android

Android groups notifications by app by default. When an app sends multiple alerts, they stack under a single notification header showing the app name and a count of how many notifications are grouped. Tap the group to expand it and see each notification separately.

You can control grouping on a per-app basis. Open Settings, go to Apps and Notifications (or Notifications, depending on your phone), select the app you want to adjust, and look for a Notification Grouping option. Some apps let you choose between "Grouped" and "Not Grouped," while others may not offer this choice.

If an app does not support grouping settings, Android will still group its notifications automatically. You cannot disable system-level grouping on most Android phones, but you can mute the app entirely or adjust its notification importance level to reduce how prominently grouped alerts appear.

How grouping works on iPhone

iPhone offers a Notification Grouping setting that applies across all apps at once. Go to Settings, tap Notifications, and scroll to the bottom to find Notification Grouping. You have three options: By App (the default), By Time, or Off.

"By App" stacks all notifications from the same app into one group, regardless of when they arrived. "By Time" groups notifications by the hour or time period they were received, so you might see one group for "10 AM" containing alerts from multiple apps. "Off" shows every notification individually, which can quickly clutter your lock screen.

Unlike Android, iPhone does not let you turn grouping on or off for individual apps — the setting applies system-wide. However, you can still customize how each app sends notifications by going to Settings, Notifications, selecting the app, and toggling notification delivery on or off entirely.

Why your phone groups notifications

Grouping exists to solve a real problem: notification overload. Without it, a busy day of messages, emails, social media updates, and app alerts would fill your lock screen with dozens of individual notifications, making it hard to see what actually matters or find a specific message quickly.

Grouping also preserves your phone's responsiveness. Displaying hundreds of individual notifications uses more memory and processing power than displaying a few groups. By collapsing similar alerts, your phone stays faster and your battery lasts longer.

From a privacy perspective, grouping can also reduce what is visible at a glance on your lock screen. Instead of seeing the full text of five separate messages, you see one notification that says "5 messages" until you unlock and expand it. This is especially useful if you share your phone or use it in public.

When grouping might not be what you want

Some people prefer to see every notification individually, especially if they use their phone for work and need to spot urgent messages immediately. If you are waiting for a specific text or email, a grouped notification might feel slower to access than a separate alert.

Grouping can also hide notifications you might otherwise notice. If you receive a message from someone important while your phone is already showing a group of notifications from that same person, the new message gets added to the group silently — you still get a sound or vibration, but the notification itself does not appear as a separate item on your lock screen.

If you find grouping frustrating, you can turn it off on Android by adjusting individual app settings, or on iPhone by changing your Notification Grouping preference to "Off." Keep in mind that disabling grouping will make your lock screen busier, especially if you receive many notifications throughout the day.

How to manage grouping for specific apps

On Android, open Settings and navigate to Apps and Notifications. Select the app you want to adjust, tap Notifications, and look for a Grouping option. If it appears, you can toggle between grouped and ungrouped. Not all apps offer this choice — it depends on how the app was built.

On iPhone, you cannot control grouping per app, but you can control how notifications appear by going to Settings, Notifications, selecting the app, and choosing between Banner, Alerts, or None. You can also toggle "Allow Notifications" off entirely for apps that send too many alerts.

If an app sends notifications you do not want to see at all, the simplest solution is to turn off notifications for that app rather than trying to adjust grouping. This prevents alerts from appearing on your lock screen and in your notification panel entirely.

Frequently Asked Questions

Will I miss a notification if it gets grouped?

No. Your phone still sends a sound or vibration for each new notification, even if they are grouped. You will hear or feel the alert; you just have to tap the group to see the individual message. The notification is not hidden from you — it is just organized differently on your screen.

Can I turn off grouping for just one app?

On Android, yes — most apps let you control grouping individually through their notification settings. On iPhone, no — the Notification Grouping setting applies to all apps at once. If an iPhone app sends too many notifications, your best option is to turn off notifications for that app entirely.

Does grouping affect how notifications appear on my smartwatch?

It depends on your device. Some smartwatches mirror your phone's notification grouping settings, while others show notifications differently. Check your smartwatch settings or the companion app to see if grouping options are available.

What is the difference between grouping by app and grouping by time?

Grouping by app stacks all notifications from the same app together, no matter when they arrived. Grouping by time organizes notifications by when you received them — for example, all alerts from 10 AM in one group, all from 11 AM in another. This is an iPhone-only option.

If I turn off grouping, will my phone run slower?

Possibly, but the difference is usually small on modern phones. Displaying many individual notifications uses slightly more memory and battery than displaying groups, but most people will not notice a significant slowdown unless they receive hundreds of notifications per day.
