How to Increase battery life of your laptop?

There are simple techniques available to extend battery life of your laptop. Some of these tips are for when you need to increase your battery at that very moment, while others are preventative measures, best implemented before your battery life comes up short.

Step 1: Click on the Start Menu and type “ CMD ” in the Start Search bar.

Step 2: The search will start and it will then display an icon of “ CMD ” . simply right click on it and select Run as administrator.

Step 3: It will open command line, now simply run the command “powercfg -energy” without quotes. (For windows 7 users.)


Simply run the command “powercfg /energy” without quotes. (For windows 8 users.)

Step 4: Now Press “Enter”.

Once you successfully execute this command , Windows will run a complete scan of your system and it will find some ways to improve performance and power efficiency.
The results of this process will be saved to an HTML file, which is commonly present in the “System32” folder of most of the systems.

To access this file, simply follow the path which will be displayed in command prompt window after completion of the command. Read This file to understand that what program in your system is consuming more power and degrading the performance.

To save power, make your computer do less in general:

  • Don’t use a screensaver. They’re unnecessary on modern displays and will drain your battery to do nothing useful when your display could be off and saving power.
  • Reduce Screen Brightness
  • Have Your Display Automatically Turn Off
  • Run fewer programs in the background.
  • Disable Bluetooth and Other Hardware Devices
  • Reduce CPU usage.
  • Avoid maxing out your RAM. If your laptop’s RAM is full, try to make more RAM available — close programs running in the background or try to upgrade your laptop’s RAM.
