One of the biggest drains on battery life is the screen backlight. You can adjust the screen brightness down under the Quick Settings menu on the right end of the Taskbar. Please don't feel like you need to turn the screen down to the point where you cannot see the screen well, but you'll probably find that you don't need the screen cranked all the way up to 100% either.

The Energy Saver feature in Windows 11 helps extend your laptop's battery life by intelligently reducing power consumption. When activated, it automatically dims your screen, limits background app activity, and minimizes non-essential system tasks.

Google Chrome's Memory and Power features can help prolong your battery life. Memory unloads inactive tabs to free up RAM, making Chrome more efficient. Power settings automatically reduce background activity and visual effects in the browser when your laptop's battery is low, cutting down on power consumption. You can adjust the memory and power settings under the 'Performance' tab.

Having dozens of Chrome tabs open significantly drains your laptop's battery life because each tab, even if not actively in use, consumes valuable CPU, RAM, and network resources. This isn't a setting you can change; this is a behavior you will need to adjust if you want to improve your battery life on your laptop. While you might be apprehensive about closing browser tabs, remember that everything is in your browser history. You can also bookmark or add to Chrome's reading list webpages you want to come back to later.
