Laptop Types

The most popular laptop type is the notebook, with a balance between portability and performance. This product line is ideal for basic work and entertainment. 

On average, a basic laptop consumes about 60 watts per hour and can last for up to 10 hours, which is sufficient for doing light tasks.

For workstations and gaming devices, the energy consumption is much higher. These devices are used for running heavy games and software or video rendering. 

The power consumption of these devices can go up to 90-100 Watts per hour. 

CPU

The CPU or Central Processing Unit is the brain of your computer. It performs all the calculations and operations on your device. 

For this reason, a running CPU takes up a large portion of overall power usage on your computer. The stronger your CPU, the more electricity it consumes. 

For example, high-performance CPU models like AMD Ryzen 7 or Intel i9 are equipped on gaming computers.

They consume much more power compared to average CPU models on Notebooks.

GPU

Similar to the CPU, the Graphics Processing Unit is an indispensable unit on your computer. It takes charge of creating and processing images on your device.  

High-end computer products, especially the gaming line, possess powerful GPU models. T

They need more power to create higher-quality images and visuals for heavy tasks like gaming and video rendering. 

For this reason, it is understandable that a strong GPU requires more electricity to operate. 

How Many Watts Does A Laptop Use?

We can conclude that a notebook used for basic tasks like learning and typing consumes 60-80 Watts per hour. 

For Macbook users, a 13-inch Macbook Pro consumes 61 Watt, and the figure for a 15-inch is 81 Watt.

Meanwhile, the number for gaming and high-end devices is 180 Watts per hour. If you use these devices for lighter tasks like video watching and reading, the power consumption will decrease substantially.

Also, laptops with a 15-inch screen size use 20% more electricity than 13-inch ones on average.
