1. Reduce Brightness to Minimum: In the beginning, we had our brightness always pumped up to the maximum, but as time wore on, we got used to having the screen less bright, especially when doing office work, writing, or reading. The antiglare screen we have helps us out with this.
2. Switch WiFi Off: The WiFi antenna included in your laptop uses up a lot of juice, so when you're trying to make your battery last as long as possible, try switching it off. When you need the Internet, just switch it back on again.3. Adjust Sleep Settings: We've tailored our energy saver preferences by putting the computer to sleep after a minute or so of inactivity. It makes sense when you're trying to reduce your energy consumption and making your laptop's battery last.
4. Uninstall or Disable Flash: We rarely use our laptop to check out Flash-based sites. You can save up to 30% of power by not using Flash. The simplest way is to uninstall Flash. This will ensure that Flash won't run amuck. There are some add-ons that can help you deal with Flash's insidious use of battery power: ClicktoFlash and Flashblock
5. Dial Down Hardware Settings: Some laptops have more than one video card, or other similar performing options. It doesn't take much to drain a battery. We've been able to drain the one of a MacBook Pro 17 in under 2 hours, when using maximal brightness and the performing video card. Select the right options to reduce your power usage. This can be taken care of by simply using the "quiet office" setting in your power profile or just by switching them manually.
