# How can I extend my laptop’s battery life while browsing?

> Extend your laptop's battery life while browsing in Comet: turn on Energy Saver and Memory Saver, adjust page preloading, and limit open tabs.

You can adjust these settings by opening **Settings → Performance**,\
or by pressing **⌘ ,** (on macOS) / **Ctrl ,** (on Windows).

***

## 1. Enable Energy Saver

Comet’s **Energy Saver** limits background activity and visual effects, such as smooth scrolling and video frame rates.\
​**Turn it on** to conserve battery when unplugged or running low on power.

***

## 2. Use Memory Saver

When **Memory Saver** is enabled, inactive tabs are temporarily paused to free up system memory.\
They’ll automatically reload when you return to them, keeping your laptop fast and efficient.

**Tip:** Choose **Balanced (recommended)** under *Memory Saver* for the best mix of performance and battery life.

***

## 3. Adjust Preload pages

Comet can preload pages to make browsing and searching faster.\
For best battery performance, choose **Standard preloading** or turn preloading off entirely.\
​**Extended preloading** is faster, but it may use more data and power.

***

## 4. Limit open tabs

Keeping too many tabs active increases memory and CPU usage.\
Close tabs you’re not using to extend battery life.

***

## 5. Keep Performance issue alerts on

Leave this setting enabled — it helps Comet automatically detect and suggest fixes for behaviors that may impact battery life or performance.
