If you’re just interested in the numbers, the answer is straightforward: an average 15-inch laptop uses around 60 watts per hour. However, this isn’t the precise quantity of food it would ingest. There are several elements that influence energy use that you may not be aware of. Charging, screen brightness, active applications, graphics card utilization, and other factors may influence power consumption.
The Factors Affecting Laptop Energy Consumption
Before we get into the elements that influence it, there are a few things to consider. Every year, a large number of manufacturers produce laptops. Companies have been attempting to make the best computer with the least amount of electricity while still working and any computer you’ve used as we progress towards better use of technology.
As a result, your laptop’s power consumption will be determined by its kind. The more extra gear you attach to it, the more energy it will require. Let’s have a look at the variables that influence power use.
1. Laptop Type [Power Consumption Is Higher In Gaming Laptops & Workstations]
The sort of laptop you’ve been using is one of the critical determinants of energy use. A basic and ordinary laptop will require roughly 60 watts per hour of electricity. It will be considerably more if a gaming laptop or any other high-end laptop. A few models evaluated in our laboratory may output much more significantly than 100W per hour, so the computer becomes quite hot and requires a cooling pad to cool down. Similarly, if you charge such computers, the cost goes up much more.
2. CPU
It is common knowledge that a laptop with a low-grade CPU or processor consumes more power than a laptop with a robust CPU such as an Intel i7 or Intel i9. The explanation for this is as straightforward as it seems. A processor that isn’t good enough will need more power to give adequate performance for your laptop, but a powerful CPU performs well with a modest amount of electricity.
3. Computer Graphics Card
The higher a graphics card’s performance, the higher its power consumption. When playing a high-end game, for example, your laptop’s GPU will give superior pictures. A high-end GPU, such as the RTX 2080, 2070, or 2060, is standard in most gaming laptops and workstations for applications like machines, For example, whining and data science.
A high-end GPU is likely to have a high-end CPU as well. In most instances, it also has a higher-quality display and a larger battery capacity, among other things. As a result, the total power consumption of all of them would be more significant. In this article, we have a section devoted to the power consumption of gaming laptops.

For example, the Acer Predator Helios 300, one of the most popular gaming laptops, features a charger with 180W power. We’ve noted in practically every laptop series as one of the greatest laptops. It uses at least 180 Watts per hour in this manner.
What Is the Power Consumption of an Apple MacBook?
If you use a Macbook, you should be aware that a standard 13-inch Macbook Pro uses 61 Watts of power from the charger, while a 15-inch Macbook consumes 87 Watts each hour.
Using the assumptions mentioned above, you may simply determine the cost of power that you may use each day and for a week. Because a Macbook uses an average of 61 Watt/h, or 0.061 kWh, and is used for around 10 hours each day, it will cost roughly 7.32 cents per week, for 51.24 cents (assuming a 12 cents/kWh power rate).
Methods for Using Less Power on Your Laptop
If you’ve already figured out how much power your laptop uses and aren’t happy with the findings, you’ll have to develop some creative methods to save energy. We’ve tried a few different techniques for our computers and have discovered a few that you may try as well.
- When the laptop is ultimately charged, make sure the plug is removed.
- Never overload your laptop since it will deteriorate the battery and use more power.
- When the battery charge reaches 10%, plug in the charger; do not wait for it to turn off on its own. This procedure demands more work, drains the battery, and consumes more energy.
- To keep the laptop cool while charging, get a cooling pad.
- Allow the laptop to cool down before continuing your work to reduce consumption.
- To prevent any system stress, update your CPU and other hardware.
- Always use the original charger that came with the product.
There are various alternative ways to consume energy that you might explore. For example, using a high-brightness screen consumes a lot of energy. This may be avoided by darkening the screen while not in use, protecting your eyes.
How can you figure out how many Watts a laptop uses?
Ultimately, knowing specific ways for calculating the actual watts utilized by your laptop is all that is required. Either way, understanding the laptop’s charger power usage and other aspects might help you estimate. Alternatively, you may just use an electricity monitor to determine how much power your computer consumes.
