Features and Settings

What are Avast Battery Saver profiles?

An Avast Battery Saver profile is a collection of settings that manage your laptop's battery usage. To select a profile, open Avast Battery Saver, then click the relevant tile on the application dashboard.

Avast Battery Saver includes 3 profile options:

  • Off: When you select the Off profile, Avast Battery Saver is disabled and takes no action to extend your laptop's battery life. Your PC operates according to your currently configured Windows settings.
  • Custom: When you select the Custom profile, Avast Battery Saver optimizes battery life according to your Custom mode settings. This is useful if you want to increase battery life without applying all settings included in the Maximum profile.
  • Maximum: When you select the Maximum profile, Avast Battery Saver prioritizes battery life over performance. Screen and Display and Hardware and Device settings are optimized to maximize battery life. You can temporarily adjust system behavior when this profile is enabled, but you cannot change default settings for the Maximum profile.
You can adjust your laptop's behavior while any profile is selected via the Bluetooth, Wi-Fi, and Brightness tiles at the bottom of the application dashboard.

How do I know which profile is enabled?

When you open Avast Battery Saver, the circle on the enabled profile tile is green (enabled).

However, if the Off profile is selected, the circle on this profile tile is red to show that Avast Battery Saver is effectively disabled.

Why did my Avast Battery Saver profile change automatically?

Your Avast Battery Saver profile may change because of the following settings that are applied by default:

  • Avast Battery Saver automatically switches to the Off profile when you plug in your laptop.
  • Avast Battery Saver automatically switches to the Maximum profile when you unplug your laptop.

To customize these settings, go to ☰ Menu ▸ Settings ▸ General ▸ Battery Saver and tick or untick the boxes according to your preferred settings.

Can I create more than one Custom profile?

No, you cannot save multiple custom profiles with different settings. The Custom profile is configured according to your Custom mode settings. If you adjust the custom mode settings, the new settings apply to the existing Custom profile.

How do I configure my Custom profile settings?

Avast Battery Saver includes General and Custom mode settings. Custom mode settings are applied only to the Custom profile.

To configure Custom mode settings:

  1. Open Avast Battery Saver and go to ☰ Menu ▸ Settings ▸ Custom mode.
  2. Configure your Custom profile via the following sections:
    • Screen and display: adjust screen brightness, adaptive backlighting, and use the drop-down menu to select a time limit after which your display turns off.
    • Hardware and Devices: define processor performance, determine when your laptop goes to sleep, turns off the hard disk, or hibernates. You can also adjust your Wi-Fi and Bluetooth settings.

Customized settings are applied automatically to your Custom profile and remain saved unless you manually adjust them. You cannot have more than one Custom profile. If you adjust your settings again, the new settings apply to the existing Custom profile.

You can access custom mode settings for the first time by clicking the Settings button on the Custom tile. After initial configuration, click (the gear icon) in the top-right corner of the Custom tile to conveniently adjust settings for this profile.

For more information about Custom profile settings, refer to the following article:

How do I adjust Avast Battery Saver General settings?
