Why do gaming laptop batteries drain so fast?


1. High Powered Processor:

The responsibility of processors is the same in any computing machine and without a strong processor, you can not do the smallest work in your device, for instance, gaming requires very heavy power to run smoothly, and there is a difference between CPU in normal laptops and gaming laptops, though it has an equivalent role to play in both.

Furthermore, to understand this let me give you a few examples, the gaming CPU has a high TDP and technology use compared to normal CPUs, for instance, most gaming machines are made under the 45watts TDP whereas for normal use 15 watts.

The large TDP (Thermal design) draws more power even on the day-to-day tasks it works on 45watts, additionally, while playing games or doing demanding work such as rendering videos or working on heavy applications your laptop also overclocks the speed, all this contributes to generating high processing system.

Also the Nano-metre in CPU measures for length, the higher nm takes a lot of energy during usage compared to lower range, and in gaming machine manufacturers use 14nm+ technology to tackle heavy tasks,  the processors made for gaming have “H” label and for normal tasks “U” label this also indicates that processor runs faster and more efficiently than other types of laptops.

This is too quite identical to processors for instance under normal laptops usually you get an integrated GPU that is connected to the CPU, so to render any image or video GPU has a long process to reach your display screen, whereas with a dedicated GPU it takes far lesser time, therefore, this is very important hardware in gaming devices.

However, these dedicated video chips are made with super powerful TGP (total graphics power), though it depends on product to product usually in lower range machines manufacturers add 60watts to 80 watts TGP card, whereas for high-end machines it can vary between 95 watts to above 130watts.

Additionally, the speed of these graphics cards is also what you have to add to the equation, this is also depending on each product it goes from 1200Mhz to above 1600Mhz, which puts pressure on the battery.

Though the fans are an important element in a gaming laptop, as its powerful equipment to manage the thermal issues in gaming laptops as on heavy usage Laptops. Heats up quickly.

However at times, these fans can move faster to control heating to keep your device as cool as possible, overall it’s very essential for longevity but drains your battery faster.

6. Multiple Connectivity, ports, and accessories:

Do you connect multiple sources while using your laptop? Well, all gamers do as they have to use accessories like headphones, keyboards, mice, and external monitors to enjoy the gaming session at its full capacity, but these all things contribute to draining the battery faster.
