1. Activate Your Laptop’s Battery Saver Option
Designed with these sorts of circumstances in mind, most Battery Saver or Eco modes will engage a number of automatic changes to lengthen usable battery life—many of the same changes we’ll be making here. This saved profile will adjust your laptop’s settings and shift components into low-power states to help you ration your remaining juice a bit longer.
Once you’ve turned on the automatic battery-saver tool, there are still plenty of steps to take to eke out even better efficiency. This is done by turning off unnecessary devices, adjusting settings to reduce power consumption, shutting down unwanted apps and processes, and adjusting your activities to use less power.
2. Upgrade Softwares and Drivers
Another option is to ditch the hard drive entirely, and upgrade to an SSD. These use flash memory to store data instead of a spinning disk, so there are no moving parts; this automatically makes them more energy efficient. In addition to improving your laptop’s battery life, SSDs also deliver faster performance and boot times than their traditional counterparts, and remove the problems associated with fragmentation.
Finally, add some more RAM to your system. RAM stores data for short-term use in flash modules, much like an SSD. The more data that can be put into RAM, the less reliant the system will be on pulling that data afresh from the hard drive. Again, reducing hard drive activity reduces the power consumption, but like an SSD upgrade, adding RAM also has performance benefits that you will notice immediately.
3. Use Hibernate Option
Although in standby mode your laptop recovers your data quickly as it is stored in RAM. It drains out battery while running on low power mode, but still on.
On the other hand, hibernating your laptop completely shut it down and doesn’t use any power. In this mode your data is saved to your hard disk and not RAM. So, this option is much safer but slows down shut down and resumes.
4. Reduce Screen Brightness
Laptop’s screen with lager display (14-inch to 18-inch) is the single component that consumes a lot of battery power. To avoid this battery loss you can lower down screen brightness to the dimmest setting you can tolerate.
However, you might need to increase brightness depending on where you are. For example, if you’re sitting under direct sunlight you’ll have to increase screen brightness.
5. Reduce CPU load
Many applications running in the background and external devices tend to put unnecessary load on the CPU which, in turn, harms the battery performance. USB devices including mouse and Wi-Fi are also some culprits which put unnecessary load on the laptop battery life. Likewise, background operations like iTunes and desktop search feature also overload its CPU and reduce battery life. So shut down all that is unnecessary, remove devices that you are not using, and reduce load on CPU to extend and improve battery of your laptop.
6. Keep it clean your Laptop
A laptop with blocked air vents will generate more heat thus reducing the life of the battery. Clean the air vents regularly to keep operating temperatures low. Allow for open space around the vents for air to circulate freely. Keep the area around the laptop clean to avoid entry of dust.
7. Turn off all 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.
