One of the oldest problems of all laptop users is short battery life. People are trying everything just to extend the life of their laptop batteries a little bit more. And in this article, we have a couple of advices which will help you to increase your laptop’s battery life as much as possible.
Adjust Screen Brightness
One of the biggest battery eaters on any modern portable device, which is laptop in our case, is the display. Reducing your screen’s brightness is a great way to significantly increase the battery life of your laptop. To reduce the brightness of your screen, hold the Function (Fn) key and press the brightness buttons on the keyboard of your laptop.
You can also use Microsoft Mobility Center to quickly reduce screen brightness. You can access Microsoft Mobility Center from Control Panel. Remember, the less bright your screen is, your battery will last more.
Turn Off Your Display After Some Time Of Inactivity
If you leave your laptop for a couple of minutes, its screen will still be on, unnecessarily draining battery. So you can set your screen to turn off after a short period of time, and save some energy while you’re not using your laptop.
Go to Control Panel, open Power Options and set your display to turn off after some time of inactivity (for example 3 or 5 minutes). You can instantly turn your screen back on, simply by moving your mouse cursor or pressing any key on your keyboard, so this could be a great power saver. And you should not have any problems with screen, as long as it doesn’t turn off while you’re working. You shouldn’t worry that it will turn your screen off while you’re watching a movie, or something, because media players set the display to stay awake while the video is playing.
Disable Bluetooth and Wi-Fi Devices
Your laptop probably has Bluetooth port, which also could be a big battery drainer. Because Bluetooth ports and similar components use laptop’s battery simply for being enabled. And since you probably don’t use Bluetooth all the time, you can disable it and save some battery. To disable Bluetooth, press the Function (Fn) key and press the Bluetooth key on your laptop.
Same story with your Wi-Fi, because Wi-Fi is also a huge battery consumer, and disabling it could definitely save some battery power. For example, if you’re working on some project that doesn’t require internet connection, there’s no need for Wi-Fi to be turned on. Wi-Fi could be simply turned off by using function keys of your laptop.
Change The Power Plan
Windows offers various power plans for various purposes. You can choose from power saving plan, to high performance plan, or even find the balance between them. So logically, since we want our laptop’s battery to last longer, we’re going to set our laptop’s power plan to power saving mode. To do that, go to Control Panel, open Power Options, and set your power plan to Power Saver.
You can make your power plan save even more battery power, with some advanced settings. Just Change plan settings, then go to Change advanced power settings, and you’ll get a handful of options which will help you to save even more power with your power saving power plan.
Hibernate Instead of Sleep
When your laptop goes to sleep mode, it uses really small amount of power to power its RAM and keep the current state of your system in the memory, which allows your laptop to wake up from sleep mode in just a few seconds. But, when your laptop goes to hibernate mode, it saves even more battery, because it places its system state to disk and powers off, using almost no power at all.
So, if you’re not going to use your laptop for some time, it’s probably the best choice to keep it hibernated. In that way you’ll be able to save even more battery than putting your computer to sleep or just letting it to turn off the screen.
Here are some additional tips on increasing your laptop’s battery life:
- Disable Screensaver – Screensaver is completely unnecessary for you, because it will simply drain your laptop’s battery for nothing. Instead of screensaver, you should set your display to turn off after some time, as mentioned above.
- Run fewer programs in the background – Open Task Manager and see which unnecessary processes are running. Close all unnecessary processes, and you will save some battery power.
- Reduce CPU usage – If you’re running some heavy, demanding programs, the usage of your CPU will be big, which will lead to battery drain. So consider to switch to less demanding programs, and your CPU won’t use as much battery power as it used before.
- Free some RAM space – If your laptop fills its RAM memory, and needs more memory, it will move data to the file on your hard drive, and this extra usage of the hard drive could also lead to the battery drain. However, this shouldn’t be an issue on modern laptops with more RAM, but if you’re using an older machine, you may consider closing all unnecessary programs in the background or even upgrading your RAM memory.
