I have 2.5 hours of laptop battery life, and still find myself frustrated when on the move or during power-cuts. Here are some tips you can use to maximize the time you can work on your laptop running on battery.
- Go to the Desktop –> Right Click –> Personalize –> Change Desktop Background –> Turn Off Windows Aero and change the theme to a simple one, preferably with a blank background.
- Go to: Windows Start Button –> Right Click on Computer –> Click on Advanced System Settings in the Left Sidebar –> Go to the Advanced Tab –> Click on Performance Settings –> Select Adjust for Best Performance
- Turn Off WiFi in case you don’t absolutely need it.
- Turn Off Bluetooth if you are not currently transferring data using Bluetooth.
- Turn Off USB Devices like External Hard Disks and Graphics card, External USB mice, Laptop Cooler etc.
- Shut Down Unwanted Programs/Applications like Folders, Antivirus Applications, Task Manager etc.
- In the notification area (usually on the right side) of the Taskbar, Click on the power button –>More Power Options –> Change Plan Settings –> Change Advanced Power Settings –>Modify all settings to save maximum power for the On-Battery state.
- In the notification area (usually on the right side) of the Taskbar, Click on the power button –> Adjust Screen Brightness, since the Display Monitor is what consumes the most power!
- Use Google Chrome Instead of Internet Explorer or Mozilla Firefox to reduce CPU and RAM usage.
- Right-click on the desktop –> Screen Resolution –> Reduce Screen Resolution to the minimum setting with which you are comfortable.
Most of these tips are applicable for Windows XP, Windows Vista, Windows 7 users as well as Mac and Linux users. Some features like Windows Aero however are specific to Windows Vista and Windows 7.
