Avast Battery Saver - FAQs

Avast Battery Saver is a tool designed to extend the battery life of your laptop by reducing internal and external power demands. You can switch between Battery Saver profiles to extend battery life as required and create your own Custom profile.

Open Avast Battery Saver using either method below:

• Double-click the Avast Battery Saver icon on your desktop.
• Click the Avast Battery Saver icon in the notification area of your Windows taskbar.

To block unnecessary power drains and improve your laptop's battery life, Avast Battery Saver applies the following actions:

• Lowers processor frequency.
• Optimizes display settings.
• Allows one-click disabling of Bluetooth and Wi-Fi.

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.

Depending on which Battery Saver profile is enabled, Avast Battery Saver may reduce your processor speed to extend battery life.

• Custom profile: The effect on system performance depends on your customized settings. To adjust processor performance when the Custom profile is enabled, go to ☰ Menu ▸ Settings ▸ Custom mode ▸ Hardware and devices ▸ Processor performance. For more information about configuring your Custom profile settings, refer to the following article:
  • Avast Battery Saver - Getting Started
• Maximum profile: This profile prioritizes maximum power savings, so you may notice a slight decrease in processor speed while it is enabled. You cannot customize the Maximum profile.

Avast Battery Saver calculates the impact of the currently enabled Battery Saver profile, and displays the estimated remaining battery time at the top of the application dashboard, next to Capacity. You can switch between Battery Saver profiles to compare the impact on battery life.

The calculated remaining battery time is an estimate based on current settings configurations. Actual battery life may vary.

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.

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

   • 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.
