But thanks to design optimizations and more efficient chips, things have changed. Gaming laptops these days can offer battery backup thats on par with the regular ones. Theyve also become a lot lighter and compact.

In this post, we compiled a list of gaming laptops with excellent battery life. We assumed you expect a decent level of performance since you want a gaming machine, so we also took that into account.

Why do gaming laptops die fast?

Gaming is a resource-heavy task. So generally its normal for the battery to drain faster when gaming. But gaming laptops tend to die fast even under moderate load. Why is that?

When designing laptops, manufacturers have to make a trade-off between performance and battery life. You cant always optimize for both of them. For example, optimizing a component for better performance can reduce its energy efficiency.

All the components [e.g: CPU, GPU] of a gaming laptop are tuned for maximum performance. So they generally use more power, thus reducing battery backup.

GPU: The hungry dude

The most power-hungry component is the Graphics Processing Unit. GPUs consume more power because they have ahuge number of transistors switching at high frequencies. A CPU has a smaller transistor count than a high-end GPU, so it doesnt need that much power.

Most GPUs in gaming laptops are rated 100W+. This means that, under high load, they can use as much as 100 watts of power. But nowadays GPUs have a built-in power-saving feature that reduces power consumption when running idle.

High refresh rate

The refresh rate of a display is the number of times it can draw a new image on it. A high refresh rate is important for a fluid gaming experience, so gaming laptops usually have screens with a minimum 144Hz refresh rate.

But screens with higher refresh rates tend to consume more power compared to a standard 60Hz or 90Hz display. This is another reason why gaming laptops have a lower screen-on time.

High CPU load

Gaming laptops usually come with high-speed CPUs. These processors are usually great at saving energy when idle, but they often reach very high clock rates [~5Ghz] and use a lot of power when gaming.

Compared to Intel processors, AMDs Ryzen series has better stats in terms of energy efficiency. So if you are really serious about battery life, buy a laptop with an AMD processor.

Portability Matters!

Since battery life is a priority for you, youre probably someone who travels with the Laptop. Or maybe Youre a college student who spends a lot of time outdoors. In any case, just having a good battery life wont cut it. Your gaming laptop needs to be portable enough so you easily take it to places.
