If we talk about the time a battery runs then it’s totally dependent on the type and quality of the battery that is being used. A cheap quality will consume quickly and work for a short time, whereas a good quality battery will last longer.

Along with the type, size, and power, the size of the display also matters in this regard. If the hardware of your laptop is bigger, an increased amount of power would be needed to charge it thoroughly.

Most probably, bigger hardware needs approximately 140 to 180 watts of power to let the device charge fully as well as effectively.

Other than display size, the brightness of the screen also matters, the brighter the screen is, more the power it consumes.

Factors Influencing The Laptop’s Power Consumption

Though the laptops are made with the idea to work on the go and generally have the feature of portability so that they can be carried anytime and anywhere we want intending to continue working.

However, a few things require excess power and more consumption of electricity as a means to function effectively.

Before we fix anything up, what we need to learn is to know about the causes of the issue and with that purpose in this article, we are going to cover the multiple factors influencing the power consumption of the laptop and making the consumption go super-fast withier even any major use.

1. Size of the laptop’s display

The bigger the display, the more energy it takes. Though, such laptops have bigger chargers than normal.

Still, the time to charge will increase and that’s why the size of the display actually matters. You need to understand that your battery is consumed earlier just because of the display of the laptop you have. 

2. CPU’s Performance

The amount of energy the laptop consumes is, directly and indirectly, related to the performance of your laptop’s CPU.

It has a major impact on battery usage. When we use heavy programs, the CPU needs to work harder and no doubt needs more energy than normal just like the rule of nature.

3. Size of the RAM

The size of the RAMs actually matters when it comes to energy consumption. The larger RAM will take a lot of energy from the laptop and result in quick battery consumption.

4. Types and Quantity of Hard drives

It’s a general fact that hard drives consume more energy than the CPU as a processor. Better quality and heavy hard drives take more power via laptops due to which laptops need to get more energy to work properly. 

5. Presence of Graphic Card

It can be commonly understood by an average man that if the Graphic cards are present in the laptop, it will need extra energy to run. Other than ordinary graphic cards, the heavy and latest graphic cards additionally consume more energy, and such installation also affects the charging time too.

WI-FI cards which are installed separately in the laptops also use the laptop’s energy and the laptops turn out to use more battery to manage required energy consumption.

8. Usage of Peripheral Devices

Connecting peripheral devices to your laptop is also another factor that’s affecting your battery consumption because all the connected devices will use the energy produced by the laptop and the laptop has the energy from the battery. Thus, using such devices indirectly means more consumption.

Tips To Follow To Avoid Quick Battery Drainage
