We have all come across a similar problem where our batteries drain way too fast, even when there seems to be nothing wrong with the laptop. It can be quite frustrating, especially if you are new to this problem. So why is the battery draining so fast?

There are many reasons why your Asus’s battery may be draining so fast. It could be something as severe as a virus on your laptop, or it could be something as simple as a faulty part that can be replaced quickly.

Continue reading to figure out why your laptop battery is draining so quickly. You may find one of these causes to be the reason.

Why Is My Asus Laptop Battery Draining So Fast?

It is quite frustrating when your battery doesn’t last as long as it used to or was supposed to. The best way to find the solution to this problem is to figure out why. Here are the many reasons your battery may not keep a charge like it used to.

Your Battery May Be The Problem

Whether your Asus laptop is new or used, the battery could be the cause of why it is draining so fast. Parts can be faulty, even when brand new. If you just bought your Asus, you need to contact the company. They will provide a new one with no extra costs.

Be sure to check for recalls on the Asus website. Your computer may qualify to be replaced or fixed at no extra cost. Don’t pay for something the company will do for you. Batteries can cost a good chunk of money.

An Update Changed Your Settings

Sometimes, when you update your computer, the settings can change, causing your battery to drain quicker than usual. To see if this is the cause, you can go into your settings and check your display settings. Sometimes the brightness level is maxed out and can be reduced.

These changes can also cause more applications to run in the background or have programs that normally wouldn’t be running to do just that. Adjust the settings appropriately to see if this helps conserve your battery life.

Your Laptop May Be Infected

One of the worst possible scenarios is that your computer may be infected with a virus. Viruses and firmware will drain your battery and make your computer run poorly. If your computer is doing any of the following, it may be infected:

  • The computer is running slow.
  • Pop-ups or browsers are opening up randomly.
  • Missing files.
  • Random downloads or applications appear out of nowhere.
  • Your computer is running hot.
  • Programs aren’t working like they used to.
  • Emails are being sent that you didn’t send.

If you suspect that this may be the case, you can run a program to scan your computer for free. If you want the viruses to be removed, you will have to invest in the program and pay the monthly fee.

You Have Too Many Applications Running

Like with your cellphone, there may be applications or programs that are running in the background that you weren’t aware of. This is especially the case if you have recently opened a lot of applications or downloaded new software.

You can check your computer to see what programs and applications may still be running. You can stop these programs, or change settings to restrict anything from running in the background.

Overwhelming Your Laptop With Connections

Anytime you run a program continuously, it uses your battery charge; this goes for connections. If you have multiple devices connected to your computer, whether a router, a speaker, or something else, your battery will become drained.

You don’t want to overwhelm your laptop with so many connections, especially if it drains your battery so quickly. You can test each connection to see which one it is, or you just remove all of the ones you aren’t using. 

How To Prevent Your Battery From Draining So Fast

Once you learn the cause of your battery life, you can determine which preventive measure to take. But many of these methods are great in general to use to make your battery last longer down the road and for you to use when you don’t have access to a power source.

Here are the many ways you can make your battery last longer:

  • Stop all applications and programs from running that you aren’t using.
  • Turn off Bluetooth or other connectivity you aren’t using.
  • Change your settings so it uses less power, like dimming the brightness.
  • Install Anti-virus software.
  • Run Anti-virus software regularly to remove anything.
  • Don’t click on random links or pop-ups.

If you have taken all the precautions, the battery may be the cause and not anything on your laptop. Contact Asus to see if you qualify for a new one with no extra costs, or you can find one online to replace it.


When your battery isn’t doing what it is supposed to be doing, it can be quite irritating. Take these steps to ensure your battery stays healthy longer. But remember, sometimes technology can have faulty parts, and you may just need to get a new battery.
