Every laptop or Netbook user these days have the same headache of limited backup time of batteries. As far as your system is new , you will have a good backup time but when it becomes a few months old you will definitely face problem of limited battery life.
So here I am giving you a solution to Increase battery life of laptop upto a sufficient extent.
There is an inbuilt command in your computer to Increase battery life as well as the performance of the system but not all users are aware of it. Some laptops directly provide an interface with option termed as “ POWER SAVING MODE ” but if your laptop is old or don’t have this feature by default , you need not to worry because you can do the same task manually.

If you have a laptop with Windows 7 installed, you can use the ‘powercfg‘ command . It will display useful information about your laptop’s energy consumption and usage. If you can understand and maintain it correctly then you can extend your Battery life and performance by great amount.
Steps to Increase battery life of laptop
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.)
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. Fix the Problem to Increase battery life of laptop.

when we open command window and “powercfg /energy” we were asked “this command requires administrator privileges and must be executed from an elevated command prompt”. so what we must do
As it says, You Must be an Administrator in order to perform this task.
Just right click on cmd and click on run as administrator…!
