Whether you’re using a Google Pixel, Samsung Galaxy, or any other Android phone launched in 2025, these features can significantly enhance your mobile experience. Here are some of the most interesting hidden features of Android 15 that you probably didn’t know about yet.
Universal Device Control
Android 15 introduces Universal Device Control, a centralized hub that lets you connect and control all your smart devices directly from your phone’s settings. From smart lights and speakers to thermostats and TVs, you can manage everything without juggling multiple apps.
How to use:
Go to Settings > Connected Devices > Universal Device Control to add and manage your smart gadgets effortlessly. This also supports cross-platform integration beyond Android devices, simplifying your smart home experience.
AI-Powered Battery Optimization
Android 15 uses artificial intelligence to analyze your usage patterns and allocate battery efficiently. This smart battery management prioritizes power for frequently used apps while limiting background activity for others, delivering noticeable improvements in battery life.
How to enable:
Navigate to Settings > Battery > AI Optimization and switch it on. Over time, your phone learns and adapts to your habits, helping you stay unplugged longer.
Notification Cooldown (Google Pixel Only)
To reduce notification fatigue, Android 15 adds Notification Cooldown, which automatically lowers the volume of repeated alerts from the same app within a specific timeframe, avoiding multiple disruptions.
Enable it:
Go to Settings > Notifications and toggle Notification Cooldown for selected apps.
Adaptive Vibration
Android 15 automatically adjusts your phone’s vibration intensity based on context. For example, you’ll get stronger vibrations when the phone is in your pocket and gentler ones when placed on a desk, improving tactile feedback while saving battery.

Custom Modes for Notifications and Do Not Disturb
Expanding on Do Not Disturb, Modes let users create custom profiles like Work, Weekend, or Sleep to finely control which notifications and calls get through.
Access under:
Settings > Modes to create and schedule smart notification profiles suited to your lifestyle.
Private Space for Sensitive Apps and Data
Android 15’s new Private Space offers a secure, separate profile on your device to store sensitive apps, data, and documents. Notifications and apps in this space remain hidden from the main profile, adding an extra layer of privacy.
Setup:

If you use multiple Android devices, Android 15’s Seamless App Continuity lets you pick up where you left off on apps, videos, or documents when switching between them.
Requirements:
Sign into the same Google account on all devices and enable synchronization to maintain your flow.

Enable via:
Settings > Display > Wallpaper & Style > Adaptive Themes.
Offline Voice Commands
Gone are the days when voice commands needed constant internet. Android 15 supports offline voice commands for essential tasks like opening apps, setting alarms, or sending texts, significantly improving privacy and speed.
How to enable:
Download the offline voice pack at Settings > System > Languages & Input > Voice Input.
Smart Focus Mode
Expanding on Digital Wellbeing, Android 15’s Smart Focus Mode not only silences notifications but also suggests relevant apps to keep you productive, like note-taking or timers when you’re studying or working.
