Seven Settings That Actually Extend Laptop Battery Life
Most battery advice is folklore. These are the changes that make a measurable difference, roughly in order of how much they help.

Laptop makers quote battery figures from light, carefully controlled tests. Real use drains faster. You cannot change the battery inside, but you can change what drains it, and a handful of settings account for most of the difference.
1. Lower the screen brightness
The display is usually the single biggest power draw. Dropping brightness from maximum to around half can add more time than any other setting. Turn on automatic brightness if your laptop has a light sensor.
2. Use the battery-saving power mode
Windows and macOS both have a mode that limits background activity and caps processor speed. For browsing, writing and video calls, you will rarely notice the difference in speed.
3. Close the browser tabs you are not using
Busy web pages keep running scripts in the background. A few heavy tabs, especially ones with video or live dashboards, can cost an hour over a working day.
The display is the biggest drain. Everything else is a supporting act.
4. Check what starts with the laptop
Sync tools, chat apps and updaters that launch at startup keep working all day. Disable the ones you do not need from the startup settings, and open them only when you use them.
5. Turn off keyboard backlighting
It is a small draw, but it adds up over a long day, and many laptops leave it on by default even in a bright room.
6. Prefer Wi-Fi to tethering
Sharing a connection from your phone costs battery on both devices. Where reliable Wi-Fi is available, use it.
7. Keep the system updated
Updates regularly include power-management fixes for specific chips. An out-of-date laptop can drain faster than the same model fully updated.
