Majority of us do not take out the battery from our laptops even while its AC adaptor is plugged in. This harms the laptop’s battery since it continues to charge and discharge several times. This process is very harmful for the laptop battery life, no matter what brand you may be using: Dell, Lenovo, HP and so on. A laptop essentially loses its charm if its battery stops going on for as long as you want it to go. It is certainly no fun searching for an outlet especially if you are outdoors. So, in this guide, we will study ways how to extend, prolong and improve laptop battery life.

1. Regular defragmentation
One of the easiest and surefire ways to improve your laptop battery performance is to defrag the hard drive. In fact: the more you use your hard drive, the greater the pressure on your laptop and especially its battery life. So improve the efficiency of the laptop as well as its battery by using the defrag option from time to time. Apple computers are better built to withstand fragmentation-so this point is not applicable to Mac computers. Make sure the battery is out and your laptop is on AC adapter when defragmenting.
2. Dim the screen
Another easy way to extend laptop battery life is to use the dim function on the laptop screen. This helps keep your PC cooler and saves on cooling system. Dim the laptop to the lowest setting that you are able to tolerate and save a lot of juice on the battery.
3. 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.
4. Take the battery out of the laptop unless you are running the laptop on it
Majority of us do not know this simple yet oh-so important tip that can help extend the battery life of the laptop. Most laptops use Lithium ion batteries, unless you have very old laptops which have Nickel cadmium batteries. A normal good quality battery has a lifetime of 600-800 charge-discharge cycles. (Every time the battery discharges and charges, it has one charge cycle less left). The heat also causes the battery to lose its charge. So every time you notice your laptop getting warm, it is evident that it is losing its charge and subsequently charging again. This reduces the charge cycles left in its life. This becomes a cumulative cycle where the battery holds a little less charge each time. Therefore, it is very important that you remove the battery from the laptop when it is running on AC adaptor. This will definitely prolong the life of the battery.
5. Add more RAM
This little tip will allow your laptop to run on external memory rather than relying on virtual memory. When it uses virtual memory, your laptop not only becomes inefficient in its power usage but also relies on the hard drive which consumes more juice. (Note that this tip to prolong laptop battery life is not suitable for running memory intensive applications and programs which already rely on virtual memory usage.)
6. Keep the battery active
Once you have charged the battery make sure you use it for at least two to three hours in a week without AC adaptor. Also do not let a Lithium Ion battery discharge completely. Start charging it as soon as it is down to 20%.A Li-ion battery takes approximately 180 minutes to charge completely. Keeping the battery working is one of the most important laptop charging tips for prolonging the life of the laptop battery.
7. Keep the laptop battery contacts clean
To keep laptop battery transfer of power efficient, keep its metal contacts clean using rubbing alcohol and a soft cloth. This is one of the easy ways to maintain and maximize laptop battery life.
8. Know the difference between hibernation and standby
Putting a laptop in hibernation mode helps you save more battery juice than its standby mode. Most people use standby to resume their work quickly or catch up where they left off; but it is best to hibernate the PC if you wish to extend the battery life of laptop.
9. Cool down the laptop
Laptops work more efficiently when they are kept cool. So check the air vents and keep them clean. If your device is heating up, get it serviced. (While it is important to keep battery cool, avoid drastic measures like freezing or refrigerating the battery!). When the battery is out while your laptop is on the AC adaptor, keep it in a clean, cool and dry place.
10. Economize on battery usage in power settings
Go to your control panel, power settings. Select the max battery settings for maximum power saving and extending battery life.
11. Go easy on the tasks
Avoid multi tasking. Do one task at a time. Keep all unwanted programs off. Avoid listening to music, working on the spreadsheet and checking the email all at once. This will keep your battery from draining off completely and also make the laptop battery last longer. Pick your priorities since many passive applications are extremely demanding on battery.
12. Choose your laptops wisely
Many manufacturers have come up with laptops having batteries that run all day long. So, if your work demands it, choose a more efficient laptop to keep its battery running longer.
13. Understand the memory effect of Ni-Cad batteries
In case you have a very old laptop, you must, at least once every week, charge its battery fully and discharge it completely. (Note that this is not needed for new laptops with Lithium Ion batteries since they do not have the memory effect). Fully charging then discharging old batteries adds to their health and prevents memory effect.
14. Use auto save wisely
MS WORD and EXCEL have an auto save feature which is great but they cause the laptop system to work harder than needed by saving your work at regular intervals. (Turn off the auto save, but turn it back on as the battery starts to run low. Make sure your work is saved too). This is one of the easiest ways to make laptop battery last longer.
15. Avoid recharging the battery when the computer is not in use
If you aren’t planning to use the laptop for a while, avoid recharging it. Also avoid buying a new extra battery that you do not plan to use.This will only cost you money and the battery will lose its ability to recharge when it is not used for a while.
16. Lower graphic usage
Shut off fancy graphic drivers and change the screen resolution. Modern graphic and video cards utilize a great deal of power. Using this simple tip can help you prolong laptop battery life.
17. Calibrate the battery
For newer laptops, use the calibrate battery feature as mentioned in the manual. This will help extend laptop battery life and keep it functioning efficiently.
