Why is Laptop Battery Draining So Fast

Laptop batteries are known for their ability to provide users with the power they need to work away from the office. However, if laptop battery draining quickly becomes a problem, it can be frustrating. To help alleviate this issue, key factors to consider when purchasing a laptop battery include weight and size. Lighter batteries tend to drain more quickly than heavier batteries, so it is important to find one that will fit your needs.

Additionally, battery life varies depending on how often you use your laptop. If you plan on using your laptop for long hours at a time, it is important to purchase a battery with more juice. Finally, make sure to keep your laptop plugged in when not in use and regularly clean any dust or debris that may be blocking the ports. By optimizing a few factors, you can greatly increase the lifespan of a battery.

Causes of laptop battery drain

There are many causes of laptop battery drain, from software to hardware.

1: Corrupted Firmware Installed 

When your battery drains faster than usual, the first thing you should do is check if the firmware on your device is corrupted. A corrupted firmware can cause many different issues, including a faster battery drain. To check if your firmware is corrupted, go to Settings > General > About and scroll down to the Firmware Version section. If the number in this section is not “XX.X” (where XX.X is the latest version), your firmware may be corrupted and you should try updating it.

Updating your firmware can be a bit tricky, so be sure to read carefully any instructions that come with the update file. Also, make sure you have a backup of all your important files before starting the update process, as there is always a risk of data loss during an update. 

2: Faulty Driver

While there are many reasons that a battery can drain faster than expected, a faulty driver may be to blame in some cases. A recent study by researchers at Purdue University found that a buggy driver can cause a laptop battery to drain twice as fast. The problem is that the driver can’t properly shut down power-hungry apps when they’re not in use. 

3: Old Battery 

Batteries are susceptible to losing their charge as they age. This problem is worsened by cold weather, which can drain a battery’s power more quickly. A battery that is several years old may not have the same amount of power as a new battery, and this can cause problems for electronic devices that rely on batteries for power. One common issue is a laptop that dies quickly even when it has been recently charged; this may be due to an old battery. 

4: Charging Cable Connected All The Time

When you’re not using your laptop, it’s best to unplug the power adapter from the wall and from your laptop. This will reduce energy consumption and help your system lengthen its lifespan. Charging your laptop while it’s off will result in the battery quickly dying.

5: Unnecessary Wireless Devices

Turns out, unplugging them can actually help the battery last longer. Keep your computer’s Bluetooth and Wi-Fi turned off if not using them. Plug out unnecessary other items that are connected to USB ports. Put your laptop to sleep when you’re not using it so it doesn’t have to work as hard.

Heavy application usage can cause the battery to drain faster. This is because many applications use more power than lighter applications. Additionally, some applications may not be well written and may drain the battery even when they are not in use. For these reasons, it is important to be aware of which applications are using a lot of power and to take steps to reduce their impact on the battery.

7: Too Many Online Browsing 

Though it may be convenient to have the internet at our fingertips, constantly checking our emails, Facebook notifications and online shopping can cause our laptop battery to drain much faster. The screen is a metaphor for one of the main sources of battery drain on laptops.

According to a study by AVG, an online security company, people who spend more than eight hours a day on their laptops browsing the internet are more likely to have a fast battery drain. In fact, the study found that people who spent more than two hours browsing the web were twice as likely to have a fast battery drain as those who browsed for less than half an hour.

This is likely due to the amount of energy that is used to keep our screens lit up as we scroll through websites and apps. So, if you want your laptop computer to last all day, try to remember to reduce your online surfing time.

8: Background Running App 

Background applications continue to run even when you’re not using them which can cause your battery to drain faster.

Some people argue that having background applications running is not really a big deal and doesn’t really affect your battery life all that much. However, others disagree and believe that it does have an impact on battery life. There have been studies done that seem to back up both arguments so it really just depends on personal preference and what you feel is best for your device.

If you’re someone who doesn’t want any background applications running on your device, there is a way to disable them. All you need to do is go to Settings> Privacy > Background apps All and disable the applications that you don’t want running in the background.
