I am using a Dell Inspiron laptop and the battery only lasts about one and half hours (my friend’s laptop works for 3 to 4 hours), though I had it fully charged. I always use it in very low performance power scheme with the minimum brightness. So what can I do to increase my Dell laptop’s battery life?
Since you didn’t mention the specifications of your Dell laptop, especially related to year model. It’s hard to say which would work to extend the batter life. But here’s a list of tips you could try:
- Regularly discharge your Dell when the battery comes to 20% or so and recharge it up again. Avoid plugging the cord all the time as this shortens the life of the battery.
- Use the right adapter. Ensure that the adapter you use to charge the Dell laptop battery is an original one or one with the correct specifications.
- Click on “Minimum Processor State” and make it 0% under “Processor power management”. For “Maximum Processor State”, select anywhere between 45% – 60%. Note: don’t go below 40% because it may make your Dell slow or freeze.
- Empty the CD/DVD Drives. Even if you don’t intend to use it, don’t leave any CD/DVDs as leftovers in the drives. A spinning drive sucks Dell laptop battery power like a sponge.
- Turn off those devices or services that you aren’t using. Turn off Wi-Fi connection or Bluetooth when you don’t use it.
- Connect less peripherals. Use your touch pad, not a wired or bluetooth mouse if you prefer.
- Kill the sounds. Mute the speakers and try avoiding the use of multimedia software to maximize the battery life. Installed sound schemes also drain a battery perceptibly.
- More RAM. Adequate RAM reduces the load on Virtual memory which by default resides on the Dell laptop hard drive. Though every extra bit of RAM uses up more power, it increases overall savings by short cutting access to the power hungry hard drive.
- Hibernate is better than Sleep. In the Stand By mode (or sleep mode), the computer turns of the hard drive and the display but memory remains active while the CPU slows down.
- Avoid Dell over-heating. Excessive heat kills battery much faster. If you can, get a cooling pad for your Dell notebook when it’s working.
