Laptop RGB power draw

Bibin Sunny · February 24

Hello, Hope you all are doing well. I recently got a new gaming laptop, rog G16. Does anyone have any idea about the difference in battery backup when we use the keyboard RGB backlight and off? I know that the LEDs dont draw too much power. However, the thing got effects and stuff like an unattended baby running through the insides of the keyboard;

Those LEDs will have very little effect on battery life.

Even on my 2007 XPS laptop, I can't tell the difference between battery life with lights on vs off and the battery on that laptop lasts like 40 minutes to begin with.

It's likely almost negligible. I remember seeing something somewhere and a full-size USB keyboard with backlighting only requested to draw something like 100mA at 5V... which is essentially nothing. And that's just how much it requested: not how much it actually uses.

I wish that i could test this somehow. Can the power consumption of RGB backlighting be compared between different laptop models, such as the ROG G16 and older laptops like the 2007 XPS?

Not directly, no. RGB vs plain white is completely different, and even just going between models manufactured by the same company can't always be reliable.
