How Much Electricity Does A Macbook Pro Use

Share This:

Are you curious abot how much electricity a Macbook Pro uses? It’s an important question to ask, as it will impact your energy bill and the environment. Let’s take a look at what you need to know about the power consumption of your Macbook Pro.

First, let’s talk about the average wattage of a Macbook Pro. A 13-inch Macbook Pro uses approximately 61 watts when in full-load mode and up to 110 watts when in high power mode. A 15-inch Macbook Pro uses 87 watts when in full load and up to 130 watts when in high power mode.

Next, let’s discuss how much electricity a Macbook Pro uses when idle or sleeping. When the display is turned on but not actively performing any tasks, an idle 13-inch model consumes 69.1 watts of power and a 15-inch model consumes 90 watts of power. When put into sleep mode, both models use only 1.22 watts of power.

Finally, we should also consider the cost associated with running a Macbook Pro. With most energy suppliers, running an average 13-inch model costs around 0.8 cents per hour whie running an average 15-inch model costs around 1.13 cents per hour (based on $0.11/kWh). The cost for both models increases when they are running in high power mode due to their increased wattage consumption.

In conclusion, it is important to understand how much electricity your Macbook Pro uses so that you can manage your energy consumption accordingly and reduce your monthly bills and environmental impact as much as possible!

Estimating the Electricity Usage of a MacBook Per Hour

A 13-inch MacBook uses approximately 61 watts of electricity per hour. That translates to about 0.8 cents per hour in electricity costs. A 15-inch MacBook uses 87 watts of electricity per hour, which is equivalent to 1.13 cents per hour in electricity costs. Other laptops with 15.6-inch screens consume about 60 watts of electricity per hour, for a cost of roughly 0.78 cents per hour, and 17-inch laptops use around 90 watts of power for a cost of 1.17 cents per hour.

Estimating the Electricity Usage of Charging a MacBook Pro

When charging a MacBook Pro, the amount of electricity used will depend on the model and how it is being charged. Generally speaking, when usig the included power adapter and a wall outlet, most MacBook Pro models will draw up to 60 watts of electricity when charging from 0% to 100%. This rate can be higher if you are using an aftermarket power adapter or are charging in high power mode. You can expect up to 110 watts in high power mode and up to 76 watts in low power mode. It’s important to note that the actual amount of electricity drawn may vary depending on the device’s current charge level and other factors.

Does a Mac Use a Lot of Electricity?

No, a Mac does not use a lot of electricity when in idle mode or with the display turned on. In fact, the iMac uses only 69.1W of power when it is idle and the display is turned on. When put to sleep, it uses only 1.22 W of power – which is quite low compared to oter electronic devices. So overall, Macs are quite efficient in terms of electricity consumption, making them an ideal choice for energy-conscious users.

Power Consumption of MacBook Pro 16

The MacBook Pro 16 uses a maximum of 99.6 watt-hours, which is equivalent to approximately 69.6 watts when converted. This amount of power can be used for a variety of functions, such as powering the laptop’s display, processor, storage drives, and other components. As the battery drains over time, the amount of power needed to run the laptop will decrease accordingly.

Cost of Running a Laptop for 8 Hours

Running a laptop for eight hours a day can cost you 24p per day. This is because the average laptop consumes 50 watts of electricity, which equates to 0.05 kWh of energy. This means that it costs 3p per hour to run your laptop. It is important to note that this wattage does not necessarily mean that your laptop will use more electricity than oter appliances – it all depends on how efficiently it is used and the type of process being undertaken by the laptop. For example, if you are running intensive applications such as gaming, then your laptop may consume more energy than if you were just browsing the web or writing documents.

Estimating the Electricity Usage of a Laptop in 12 Hours

When in active use, a laptop would consume approximately 840 Watts of electricity in 12 hours. When in stand-by / sleep mode, the laptop would consume approximately 300 Watts of electricity in 12 hours. Therefore, depending on the usage mode, a laptop will consume between 300 and 840 Watts of electricity in 12 hours.

Estimating the Electricity Usage of a Computer in 24 Hours

The amount of electricity a computer uses in 24 hours depends on the type and size of the computer. Generally, laptops use btween 30 and 70 watts of electricity in 24 hours, while desktop and gaming computers use between 200 and 500 watts of electricity in 24 hours. Assuming an 8-hour usage period per day, a laptop would use approximately 2.4 kilowatt-hours (kWh) of electricity in 24 hours, while a desktop or gaming computer would use approximately 8 kWh in the same time frame.

The Benefits of Charging a MacBook Pro Every Night

No, you should not charge your MacBook Pro every night. Regularly charging your laptop to 100 percent can damage the battery over time and reduce its overll lifespan. Instead, you should aim for a charge between 40 and 80 percent whenever possible. If you need to top up your battery, plug it in for an hour or two before unplugging it again. Additionally, avoid fully discharging the battery regularly as this can also cause damage.

Understanding High Energy Usage on Mac Computers

Your Mac is using a lot of energy because it’s busy running multiple applications and scripts that are either open in the background or actively beng used. This can include heavy-duty tasks like video editing, gaming, or streaming, as well as webpages that are constantly refreshing content, downloading large files, or running complex scripts. The more applications and scripts your Mac is running at once, the more energy it will need to power them all. To reduce the amount of energy your Mac is using, try closing any unnecessary tabs or applications that you’re not actively using, and consider uninstalling any programs or plugins that you no longer need.


The Macbook Pro is a powerful and efficient computer that is perfect for the modern user. It offers a variety of sizes to suit different workflows, and its high power mode can provide up to 110 watts of power for demanding tasks. Furthermore, the Macbook Pro’s low power mode can reduce energy consumption to as little as 76 watts, while stll providing excellent performance. The idle mode consumes only 1.22 watts of power and provides up to 69.6 watt-hours (14-inch model) or 99.6 watt-hours (16-inch model). With its cost efficient operation and impressive features, the Macbook Pro is an ideal choice for those seeking a reliable and powerful laptop computer.
