  • Google cut seven billion daily Android Chrome notifications using layered defenses
  • Chrome now limits abusive sites, revokes permissions, and blocks high‑volume spam
  • Android improvements simplify managing alerts and reduce scam and malware exposure

Google says it has cut the number of notifications Chrome users get on their Android devices by seven billion a day.

In a new report, the company outlined how it has built a multi-layered defense system to shield its users from unwanted notifications, protecting them from spam and malware, and helping their devices’ battery last longer.

Most importantly, Google says the achievement significantly improved the overall user experience on Android.

Notification bombardment

For the longest time, individual websites were allowed to send push notifications directly to their users’ phones, even when they were not actively browsing them.

When a user visits a certain website, they get prompted to “show notifications”, and if they tap “allow”, the website starts sending the alerts. Sometimes, users do it without fully realizing what they’re agreeing to.

Once granted, the notifications (sent through Chrome) get shown next to other alerts (such as the ones coming from WhatsApp, Gmail, or other apps).

Unlike other notifications - which usually alert users to unread messages, calendar events, or similar - these mostly promote new content, deals, or other updates. They can also alert users of breaking news, which is arguably the most useful type among the ones mentioned here.
