Why Do Gaming Laptops Have Bad Battery Life? – Few Reasons

Gaming laptops have bad battery life because they require a lot of power to operate. This is because they have torender stunning graphics , which requires a lot of processing power.

A gaming laptop can easily burn through a full charge in just a few hours. The main reason is that gaming laptops are packed with powerful hardware.

But one area where laptops still lag behind their desktop counterparts: is battery life. Gaming laptops, in particular, have notoriously bad battery life. 

Gaming laptops have come a long way in recent years. They used to be big, bulky, and heavy with poor battery life. 

But now, they’re thinner, lighter, and more powerful than ever before. However, one thing that hasn’t changed is their battery life. It’s still terrible.


Let’s look at why gaming laptops have such poor battery life and what you can do to improve them.

Here are few Reasons:

Larger And Faster Processors (CPUs):

In 2022, AMD’s Ryzen ThreadRipper 3990X desktop PC processor, which has 64 cores and 128 threads, is anticipated to be the fastest CPU in the world. 

Normal laptop batteries can last much longer thanks to these processors’ power restrictions, but they perform poorly while multitasking and executing.

CPU-intensive tasks. They are only useful for running simple applications and doing your usual chores.

Processors with fewer power restrictions, like the Intel Core i7-4700HQ and Intel Core i9-9980HK, are available in the best gaming laptops. These processors have an “H” suffix at the end, which denotes high performance.

A smoother gaming experience is produced by high-performance CPUs’ faster processing speeds, which have higher maximum clock rates. 

This drawback is increased power consumption, heat production, and short battery life. These processors also typically have multiple cores.

Therefore, larger and faster processors have very important for gaming laptops.

Playing High Hardware Demanding Games:

As a general rule, the more difficult it is for your laptop to operate, the quicker the battery drains. High-performance games and background processes both drain battery as a result of this.

Cyberpunk may cause your gaming laptop from 2014 to burn out if you try to run it at its highest graphics setting. You’re making your gear work harder than it should, consuming more battery power so each part can keep up.

This is an age-related issue that will only worsen as your laptop ages. More complex hardware is needed to run newer games. Thus your laptop may have an arbitrary best-by date.

Games nowadays are getting more demanding in terms of hardware. This is due to the ever-growing demand for better graphics, higher frame rates, and other advanced features. 

The problem is that all of this comes at the cost of battery life. High-end games can easily eat through a laptop battery in just a couple of hours, which can be a major pain for gamers.

The only method to stop this battery-draining issue is to update your hardware.

Therefore, this is just the tip of the iceberg when it come to system settings and battery life.

RGB Lighting:

RGB LEDs are short for red, blue, and green LEDs. These three colours are combined in RGB LED devices to create over 16 million different shades of light.

Be aware that not every hue is conceivable. 

RGB lighting in laptops is one of the most popular features in recent years. Many laptop manufacturers have RGB lighting built-in to their keyboards.  

Many video games enjoy being played at night or under dim light. Gaming laptops have illuminated or backlit RGB keyboards, which are uncommon in standard computers, to make life easier. 

They reduce the likelihood of pressing the incorrect keys by making it simple to place your fingers on the appropriate keys.

Although the illuminated keyboards use less electricity, they still need to be powered, which shortens the battery life.

Louder Speakers:

In most circumstances, playing music louder than normal will deplete the device’s battery life more quickly than usual.

If you’re a laptop user, you’ve probably had the experience of your computer’s speakers sounding terrible. 

This is usually because most laptops have awful speakers. But there’s a way to fix that by getting louder speakers. 

There are a few things to consider when looking for louder speakers for your laptop:

  • You’ll want to ensure that the speakers you’re considering are compatible with your laptop. 
  • You’ll want to think about how loud you need the speakers to be. 
  • You’ll want to consider the price. 
  • You’ll want to ensure that the speakers you’re considering are compatible with your laptop’s make and model. 

It’s crucial to remember that even though gaming laptop speakers have improved, they still fall short of a dedicated surround sound system or a good set of gaming headphones in terms of sound quality.

Playing On Too High Brightness:

Increasing brightness uses more battery power, and decreasing brightness will reduce battery usage.

According to a recent study, playing games at high brightness can shorten the lifespan of your battery. 

The study found that playing at high brightness can cause your battery to degrade faster and that the degradation is more severe the higher the brightness is set. 

A laptop screen consumes more energy than any other component, so reducing screen brightness is the easiest way to cut down the battery drain.

To extend the life of your battery, it’s best to play on low or medium brightness. You can also try turning off some of the graphics-intensive features in your games to help save battery life.

Wrong System Settings:

Changing your system settings is related to our previous discussion about brightness.

Power-saving features are automatically built into your laptop. When you receive a notification, and your laptop screen darkens, the threshold for these adjustments to take effect is about 20%.

Most individuals believe that this is merely a low battery alert. They’re mistaken. You may completely customise and take advantage of all the features in this power-saving mode to help you preserve your battery life.

When the mode activates, what it modifies, and how it prioritises power-saving above performance are all configurable.

Even some laptops have built-in sliders that let users quickly and easily choose between high performance and extended battery life.

On average, gaming laptop batteries will last between 2-4 hours. This will vary depending on the type of game you are playing, the graphics settings you are using, and how bright your screen is set.

A variety of factors determine a laptop’s battery life. The most important factor is power consumption, which is determined by the type of processor, graphics card, and other components in the laptop. 

However, other factors affect battery life, such as the screen brightness, the number of applications running in the background, and even the age of the battery. 

The average lifespan of gaming laptops is roughly three years, but with proper care and maintenance, you can expect them to last at least five years.

How To Increase The Battery Life Of A Gaming Laptop?

Gaming laptops need more electricity than customary laptops, which causes the battery to drain more fastly. This is because gaming laptops need to be able to handle more demanding tasks, such as running games at high setting.

 There’s a way to fix that and extend gaming laptop battery life:

  1. It would be better to buy a gaming laptop. 
  2. It would help if you closed any applications you are not using.
  3. Reduce the brightness of your display as much as possible. 
  4. Make sure your battery performance slider is set to high. 
  5. Wi-Fi and Bluetooth should be turned off if possible. 
  6. Make certain all USB peripherals are unplugged or turned off.


In this post, we discussed why gaming laptops have bad battery life. We covered the main reasons, including the powerful hardware, the large screen size, and the high-quality graphics.

The most important one is that they have very powerful hardware that requires a lot of power to run. This means that the battery will drain quickly when you’re gaming. 

Additionally, gaming laptops tend to have high-resolution screens that also require a lot of power to run.

We also looked at ways you can improve your laptop’s battery life. Finally, gaming laptops often have features like backlit keyboards and RGB lighting that can also drain the battery quickly.
