Okay, so you are facing this problem, where your computer’s battery drains at a crazy pace. And let me get this out of the way, the computer I obviously mean laptops, not desktops, as laptops have their own built-in battery pack, which is rechargeable and can last for a while, without direct electricity intake.
Desktops don’t have batteries, so if there is no electricity to power your desktop, it won’t turn ON. Obviously, everyone knows that.
Why is my computer battery draining so fast?
There could be several reasons why your computer battery is draining so fast, including running too many programs at once, having too many tabs open in your web browser, using power-intensive settings, or having a battery that needs to be replaced.
How can I check what programs are using the most battery?
On Windows, you can open the Task Manager and click on the “Battery” column to sort programs by their power usage. On a Mac, you can use the Activity Monitor and sort processes by their energy impact.
What are some power-saving settings I can use to extend my battery life?
You can adjust your display brightness, turn off Bluetooth and Wi-Fi when not in use, put your computer to sleep when not in use, and reduce the time it takes for your computer to enter sleep mode.
Now that we have that sorted out, there are many reasons for the question Why Is My Computer Battery Draining So Fast? Some of those reasons or problems can be easily fixed.
Even you would be able to do that. But some are very complex and require technical support from professionals.
In this article, I will inform you about some of the reasons for your batteries’ fats drainage and would also give you the solutions to fix them.
Brightness:

Now, it is possible that your laptop is currently on a high brightness level. Which is causing this rapid battery drainage.
Keep in mind that your system’s display consumes a lot of power, especially if you are using an advanced laptop, which has a high-resolution quality and the brightness can be increased by a lot.
So, my first recommendation would be to check your brightness level. And it is very simple to do. Some laptops have brightness keys on the keyboard.
You can press the brightness increase and decrease keys and it would show you your current brightness level. Now you can use these keys to adjust the brightness so that it doesn’t consume battery that much.
If your laptop doesn’t have a brightness key or another way to do this is to go to settings. Then click on the system option. When the window appears choose the Display option from the sidebar.
Now, this will show you different display options and settings, including adjust brightness level option. Now, you can decrease the brightness or you can turn On the automatic change option.
What this option does is that it changes your display’s brightness automatically when lighting changes. Keep in mind that this option might not be available for all laptops.
High-Performance Mode:

Many laptops have this high-resolution mode, which pushes the system to its full extent. Which is great to give you the best possible performance your laptop can give you.
But this can be very heavy on your laptop’s battery. That’s why most laptop’s come in optimized mode by default.
But if you want to check if your system is currently running in high-performance mode, then press the windows key and R key. When the search box shows up enter powercfg.cpl in it.
This will take you to another power options window. Now, here you can check if your system is in high-performance mode or not. But not every laptop has this feature. Even most laptops don’t have it. But if you do then you can check it out.
Heavy Softwares:

Maybe the reason why your battery drains very fast might be the type of apps you use.
For example, if you play high-performance games on your laptop, then it would drain your laptop’s battery. Because these games need your laptop’s highest performance, to give you a smooth gaming experience.
Not just games, but even some software are so heavy that they require high efficiency from the system and puts a lot of load on the battery.
So, the best and only solution to this would be to not use your laptop for such stuff, if it’s not made for it. Instead, buy a gaming laptop or a very performance laptop, because those are made especially for that and are good at doing that.
Keyboards BackLight:

Some of the laptops have backlights for their keyboards. It’s mostly just expensive laptops that give their owners this feature.
And it has many advantages, one of them being that you can easily see and type while in the dark. But the problem is that those lights do take some battery. And might result in quick overall battery drainage.
If you are okay with that you can keep them ON and have your laptop plugged in most of the time. But if you don’t want that anymore.

Or for just this one time you want to turn it off, so your battery can last for a while. Or you mostly work under bright light and have no need for the keyboard’s backlight. Then you can turn it off. On some laptops, you can turn this feature off by pressing the function (fn) key and the F5 key at the same time.
But if that doesn’t work for you then you can go to settings, then go to the Devices and open the Typing option for the sidebar. This should open your keyboard’s settings and would give you a toggle to turn the keyboard backlights On or Off.
Connectivity:

This includes Bluetooth, wifi, hotspot, etc, and even externally connected devices through HDMI or USB, etc. Now, it’s Okay if you are using these options or if you need them On.
But if there is no need for Bluetooth turned On, then I would recommend turning it off. It’s doing nothing but just draining the laptop’s battery. The same goes for all of the others.
Now for the externally connected device, you can just disconnect them by pulling the cable or you can go to my computer and eject the device properly.
Or you can go to settings and then open the devices options, where you can turn the Bluetooth Off, or disconnect any device. For wifi, Vpn, etc you can open settings and then Network & Internet option. This would allow you to turn wifi etc off.
So, these were some of the most common problems or reasons for fast laptop battery drainage. I’m not saying that there can’t be anything wrong with your laptop.
You always have the option to take it to a professional and consult that person about it. And if you have been using your laptop for a while, then it is possible that it is time to change its battery and adds a new one.
