Avast Battery Saver for Android: Getting Started

How to Use Avast Battery Saver

Battery Saver is a free application that improves the endurance of your battery between recharges. The app identifies and stops the apps that drain your battery, and manages your device settings so that features that consume a lot of battery only turn on when you need them.

Refer to the following sections to get started:

Navigate the Battery Saver interface

Open Battery Saver on your device by tapping the Avast Battery Saver icon.

The Battery Saver interface comprises five tabs at the top of the screen.

Each of these tabs consists of different information or actions that you can perform. The tabs include:


  • Verify the amount of time until your battery is exhausted (or recharged if the device is currently charging).
  • See the number of apps currently running on your device.
  • Stop unnecessary apps to extend your battery life.


  • Verify which Battery Saver profile is currently active.
  • Configure the settings of your Battery Saver profiles.


  • See the number of apps that you have stopped.
  • Configure your Battery Saver settings.
  • View a list of currently running apps, specify the apps that you want to continue running, and stop those that are consuming too much battery.
  • Get help or provide feedback.


  • See the percentage of used space on your device.
  • Access Avast Cleanup to free wasted space.

Set your Battery Saver preferences

You can set or change your Battery Saver preferences at any time.

Follow these steps:

  1. Tap (or swipe to) the Tools tab, then tap Settings.
  2. Tap one of the following settings and specify your preferences for that setting:
    In Settings, you can also view information about Battery Saver by tapping About.
    • System tray icon: select the information that you want to appear at the top of your device screen at all times (Battery percentage, Apps running, Profile, or Nothing).
    • Notifications: turn off any notifications that you do not want to receive. Notifications for your Battery Saver profiles can be set from the settings screen for each profile.
  3. Tap the back arrow to exit Settings.

Your Battery Saver preferences are set.

Configure your Battery Saver profiles

Battery Saver includes five usage profiles which determine the battery-saving settings of your phone based on certain triggers. For example, your battery-saving profile can change when you are at home, when you are at work, and so on, according to a detected location or Wi-Fi network.

Follow these steps:

  1. Tap (or swipe to) the Profiles tab.

    A list of profiles appears with the active profile highlighted.
  2. Tap the name of the profile that you want to configure, then tap the Settings icon that appears.

    A list of configurable settings opens.
  3. Set an activation trigger for the profile:
    • Work or Home: select a Wi-Fi network.
    • Night: specify a time period (for example, from 11:00pm to 6:00am).
    • Emergency: select a percentage of remaining battery power, or keep the default setting of 25 percent.
    You cannot set an activation trigger for the Smart profile because this profile activates automatically when no other profile is active.
  4. Turn on or off the following activation options:
    • Auto activate: turn on if you want the profile to activate automatically when your activation trigger is met.
    • Notify when profile is activated: turn on if you want to be notified each time the profile becomes active.
  5. Specify your Profile settings preferences.
  6. Tap the back arrow to return to the list of profiles and repeat the steps if you want to modify the settings of another profile.

Your profile settings are updated.

Stop running apps

To further preserve the life of your battery, Battery Saver enables you to stop the apps that are running unnecessarily in the background.

The easiest way to do this is directly from the Applications screen of the app. From this screen, you can see the number of apps that are currently running, and tap Stop Running Apps to immediately freeze and prevent them from consuming unnecessary battery power.

Alternatively, you can stop your apps from running, and also view further information about them from the Tools tab.

If you have not already granted the Accessibility permission to Battery Saver, you are prompted to do so when you use Battery Saver to stop running apps. Battery Saver is unable to fulfill this action without this permission.

Follow these steps:

  1. Tap (or swipe to) the Tools tab, then tap Running apps.

    A list of currently running apps that are consuming more than 1 percent of your battery power appears.
  2. Tap Show all apps (draining less than 1%) if you want to see all of the apps that are currently running.
  3. Tap next to a specific app to stop just that app, or tap the Stop Running Apps button at the bottom of the page to stop all apps at once.
  4. Tap the back arrow to return to the main screen of the Tools tab.
    On the main screen of the Tools tab, you can see the number of apps that have been stopped on your device. Tap the menu icon to change the period that this statistic is calculated for.

Restart any apps that you want to continue receiving notifications for by reopening them on your device. If you want the App Stopping function to ignore certain apps, go to the Allowed apps section on the Tools tab where you can see a list of preselected apps that are not affected by this function. Tap the Add icon to add other apps or tap Remove to deselect apps that you do not want to be ignored.
