Why Do Gaming Laptops Have Bad Battery Life? [5 REASONS]

Battery backup of a laptop is one of the prime concerns among users because many times while traveling, it really matters as to how long your laptop battery will provide backup. Also, people tend to be knowing the battery life of the laptop while buying.

Gaming laptops have bad battery life in most cases because of the high-performance CPU and GPU that are used in them which generally consume battery more than 5 times as compared to what a normal laptop would consume. Also, in gaming laptops, high-resolution displays, RGB backlit keyboards, and other peripherals are there which all puts more pressure on the battery.

Why Do Gaming Laptops Have Bad Battery Life

I have owned a gaming laptop for a long time in my college days (I am a BCA graduate, so I have been a computer guy all my life, and have worked with various laptops), thus, I totally related to this, and I will be sharing more information about why actually gaming laptops have bad battery life, and why the battery drains so fast. Also, I will put some light on how to increase battery life on a gaming laptop.

5 Reasons Why Do Gaming Laptops Have Bad Battery Life


1. High-Performance CPU

Normal laptops are made in a way that when you are out of the power outlet, you can still work with it. That is why the battery is the main focus while building these laptops. On the other hand, gaming laptops are generally made considering you sitting in your house and playing games. So, the battery is never the focus while building gaming laptops. The main focus is high-performance/high-speed processors which can provide optimum performance without any lag even when you are playing some of the high-end games. 

Generally, CPUs with 4 Cores are used in a normal laptop whereas CPUs with 16 cores are used in Gaming laptops which generally need more power, and thus, the battery drains out quickly. Manufacturers are only concerned about the performance and not the battery backup when it comes to gaming laptops

As I already said earlier, since the battery is never the focus while building these gaming laptops, they don’t have great batteries but great processors are there which consume more power than a normal processor. Thus, the battery drains out quickly in gaming laptops.

2. Dedicated GPU

In normal laptops, there is a GPU included with the processor which supports normal video streaming but in gaming laptops due to the need of streaming high-resolution games, there is a need for powerful GPUs. Thus, there is a separate GPU included which is more powerful than the default one. This dedicated Graphic card offers to run high-resolution games without any lag or drops in frame rate.  For a great gaming experience, a dedicated GPU is indeed required. That is why powerful GPUs are included in gaming laptops.

These high-end dedicated graphics cards might use about 125-135 watts of power as compared to an integrated graphics card which only uses about 40-45 watts of power. Since, more power it needs, the battery drains out quickly.

3. High-Speed Fans

If you compare laptops with Desktop computers, laptops are very compact and everything such as HDD, Motherboard, and other hardware must fit in a small area. Due to the small space, there is less space for airflow, and this makes the laptop heat up quickly. Thus, in normal laptops, 1 single fan is integrated to take out the heat generated by the CPU. But, in the case of a Gaming laptop, a high-speed CPU generates more heat, and also, the GPU produces heat as well. Thus, manufacturers fit 2-3 high-speed fans for better airflow which would prevent overheating. Overheating must be prevented because it would reduce the overall performance of your laptop or it would be restarted automatically as well.

So, these high-speed fans are used to keep the laptop’s overall temperature in control. But, these high-speed fans drain out the battery quickly.

5. RGB Backlit lighting

Gaming laptops are made to offer a great gaming experience, and most gamers love to play games in a dark room. RGB backlit lighting helps them see the keyboard keys properly in the dark. Moreover, this keyboard lighting thing is just to give something more to gamers. It has not much use anyway. But, when it has, it does eat up your laptop’s battery to great extent.

These are a few reasons that make gaming laptops battery have bad battery life. There may be more reasons such as too many external peripherals attached to the laptop, bigger screen size, etc.

How to Save Battery on a Gaming Laptop and Improve Battery Life?

1. Keep RGB Backlit lighting Off

You do have the option to turn off the Keypad light on your laptop. So, do that, and it will surely save a bit of battery on your gaming laptop. You must have 1-2 keys on your keyboard which would be for increasing and decreasing the lighting. keep pressing the decreasing one, and it will completely off the light. Different brands of laptops may have different options to do it.
