Laptop Watts Consumption Based on Stage

Another factor that affects how many watts a laptop use is the use stage. Your laptop's power consumption varies depending on whether it is in sleep mode, working mode, or standby mode.

The most common laptop wattage across various brands is 65W, the maximum in high-performance mode. However, the stage of laptops varies over different periods. Usually, it remains in the Off stage for around 14 hours, 0.3 hours in sleep mode, and around 9 to 10 hours in idle or high-performance mode.

So, let us summarize the figures in a table for better readability.

Active mode (incl. high performance and active but idle modes)








How Many Watts Does A Gaming Laptop Use

An average gaming laptop's wattage depends on Graphics Card TGP, screen brightness, CPU wattage, and various hardware settings. It usually falls in the range of 30W and 350W. The wattage may increase on high-performance settings as these laptops use multiple fans, have a high display refresh rate, and have higher hardware configurations. Again, the wattage changes with running mode, screen brightness, etc.

How Many Watts Does A Laptop Use Per Month/Per Year?

Generally, a laptop uses 30-70 watts of electricity and can consume more than 100 watts. If it is a gaming laptop, it might consume anywhere between 300W and 500W. How much electricity your laptop consumes daily will impact its consumption in one month and year. If we assume you are using the computer for 8 hours a day (average), here is the monthly electricity consumption per year for different laptop wattage.

What Factors Affect The Laptop Wattage?

Several factors influence the laptop's wattage, performance, and battery efficiency. Understanding these key factors can help you reduce the overall battery performance and lifespan.

Screen Size: The larger the laptop screen size, the more power or wattage it consumes. If you wish to lower the wattage or conserve some power, you can turn on the power-saving screen modes.

Brightness: The screen's brightness can also affect the total power consumption. If you are using a large laptop with a high brightness level, it will consume more power.

Graphics Card: Your laptop's visual processing influence and performance capabilities can influence the wattage consumption. While performing resource-intensive tasks that demand more energy, it is best to turn on the power-saving mode or put the laptop to sleep to minimize power drain.

Battery Condition & Charging Practices: The laptop's battery condition and your charging habits can impact the wattage usage. For example, older laptops require frequent charging and more power than the latest ones.

How Much Does It Cost to Power A Laptop?

You might have noticed that the electricity bill only includes the total energy consumption, not how much any appliance contributes to the final bill. Here is the table where we reveal the monthly and yearly costs for charging 50W of laptops in different states.

How to Reduce The Laptop Power Usages

In order to reduce the power consumption of the laptop, the first step is to understand the current usage. A portable energy monitor is one of the ways to measure how much power is being used by the laptop.

Alternatively, you can even use online calculators or tools that estimate power consumption based on usage patterns and laptop specifications. Once you know how many watts does a laptop uses, the next step is to follow some tips to reduce the laptop's power usage.

  • Use Power Saving Mode: Many of the latest laptops have a power-saving mode that draws less power. You can turn the mode on when you don't want maximum performance.
  • Reduce Screen Brightness:A laptop's screen is one of the heaviest components in terms of power consumption. You can converse wattage by dimming the screen brightness.
  • Activate Sleep Mode Faster: According to the default settings, a laptop needs to be inactive for 30 minutes before it enters sleep mode. You can reduce the power consumption by setting the device to sleep mode faster.
  • Run Few Background Apps:The applications running in the background can impact how much power the laptop is consuming. You must close anything you are not using to cut the overall consumption.
  • Invest in a Solar Generator: Even if you are using a new laptop for hours, it'll consume a lot of electricity. Jackery Solar Generators are portable and durable charging solutions that can keep your computer charged for extended periods. It's a great battery backup solution that can keep gear powered during home outages, brownouts, blackouts, and even outdoor adventures.

Laptop Wattage FAQs

How much electricity does a laptop use? How much electricity does a laptop use per hour?

If you use your laptop for 8 hours, you will use around 500 to 1000 watt-hours a day. The electricity consumption of a laptop is 65 Watts per hour in high-performance mode, while it can go down to 25 watts per hour in sleep mode or standby mode.

How many watts does a laptop use in 8 hours?

If the laptop uses between 50 and 100 watts of power per hour, it will consume almost 150 to 300 kWh in eight hours.

Does leaving a laptop plugged in use a lot of electricity?

Modern laptops or computers are designed to stop charging when they reach full capacity, so keeping them plugged in won't result in overcharging. However, keeping the computer plugged in all day will lead to electricity usage. The laptop charger will continue to convert AC electricity from the AC outlet into DC (direct current) to charge the device but does not power anything.

How to increase the laptop battery life?

The battery life of any ultraportable computer is 14 hours or more. However, paying close attention to factors like power setting modes, ambient room temperature, and how many apps are running at a time can help increase the battery life. Here are some more ways to extend the battery life of a laptop.

  • Turn Off Keyboard Backlighting:If you often work in dark spaces, you might use the keyboard backlighting. While it is pretty helpful, it can drain the battery. Turning off the backlighting to improve the battery life.
  • Unplug External Devices When Not in Use:Keeping an external hard drive, a phone, or an external display plugged into a USB port can drain the battery's power and reduce its life.
  • Keep the Laptop Cool:If you store and use the laptop at an average operating temperature or even slightly lower, it will extend the battery's lifespan and make it more efficient. You must avoid using laptops in hot rooms or under direct sunlight.

Final Thoughts

How many watts does a laptop use is a very subjective question because many factors influence the power requirements. However, the average laptop wattage spans a wide range, i.e., 30 to 2000 watts, with 65 watts as the most popular requirement. Since the power cost of using a laptop can add up quickly, investing in a solar generator helps you cut your power bill cost and have a green energy source. The Jackery solar generators are available in various configurations so that you can easily choose the best for you.
