If you work on a laptop, you are likely to encounter several issues that may affect the laptop’s performance. One of them will know that the laptop’s battery never works as long as it should. So why is the laptop’s battery quickly depleted?

To eliminate the problem, it is necessary to emphasize the factors that cause the problem. This article will list some of the most common causes that can affect battery life. We also offer practical solutions to extend the life of your laptop’s battery.

Why Does My Laptop Discharge So Fast?

If this investigation led you here, you’re probably looking for a solution. But before we list them, we need to analyze the reasons that affect battery life and encourage you to recharge them more often.

You can charge your battery at home or work, but it can be a little more complicated on the go. The idea is to work with a laptop, to have a portable device that you can take with you wherever you go. Here are a few reasons why your laptop’s battery runs out too quickly.

1. Your battery is old

The average life of a battery pack is determined by several factors, including the type of battery pack, how often the notebook is used, and the type of applications it uses. But most importantly, the battery life depends on your age. The old battery probably runs out too quickly, and you will have to replace it.

On average, the battery runs efficiently for 2 to 4 years or up to 1000 full charge cycles. After that, you can still use the battery, but a little less every time it starts to work.

After all, you can’t work with your laptop without the charger because the battery won’t hold the charge. So if you notice that the battery does not hold more than 25% of its capacity or is fully charged, it is time to buy a new battery.

2. Too many processes in the background

Before replacing the battery, check the Task Manager function, and you may find the cause of the performance degradation. You can work on a program or application without knowing that someone else is using the battery when you are not using it. The task manager informs you about the power consumption of each application or program.

If you feel that the battery is not working as long as it should, stop the processes you are not using to keep the charge. You can also prevent third-party applications from starting automatically by making the battery last longer. Clicking the Exit Task button completes the process and extends the battery life.

3. Your brightness is too high

You may not know it, but a small change in brightness can seriously affect battery performance. You probably already know that by reducing the brightness of your smartphone, the battery will last longer. The same goes for your laptop.

By lowering the brightness level from 100% to 50%, you can enjoy an extra 30 or 60 minutes, depending on what other applications and programs you run on your laptop. However, if you always turn down the brightness, your battery probably lasts longer than the average of 2 to 4 years.

4. You use your laptop at hot temperatures

The ambient temperature can have a huge impact on the performance of your battery. High temperatures accelerate chemical reactions in the laptop’s battery and affect performance over time. It is not recommended to use the laptop at temperatures above 90 degrees Fahrenheit. Therefore, do not leave the notebook in direct sunlight in places where the battery may be too hot.

At the same time, very low temperatures should be avoided. Cold temperatures can shorten battery life due to condensation, which can cause premature damage to the battery.

5. Incorrect charging and discharging

Even if you leave your notebook permanently connected, the battery will stop charging when it reaches 100%. If you leave your laptop connected, your battery will not be damaged because lithium-ion batteries have internal circuits that interrupt the charging process when fully charged. However, a laptop’s battery, such as a smartphone or a tablet, works best when it is between 20 and 80 percent.

If you do not charge the battery pack until after turning off the notebook, you are putting too much pressure on the battery pack. Instead, try charging the battery before it reaches 0%.

To extend the battery’s life slightly, consider using it less frequently. If you already have a power outlet nearby, you can remove the battery pack to avoid putting unnecessary strain on the notebook’s battery pack.

6. Games

The GPU or graphics processor is an electronic circuit that uses memory to create images for games quickly. However, the batteries will probably not be sufficient to charge the GPU. Therefore, using the battery during a game will slow down your game, which will also negatively affect battery life.

Moreover, the GPU is not the only culprit if you are looking for a reason to relieve the battery while playing the game, for example, if you are looking for a battery that is too low for your computer. B. to turn on your screen. Most laptop batteries can store between 60 and 80 watts of power when a laptop is used for gaming. However, it generally takes between 140 and 200 watt-hours, which is much more than your battery can deliver.

Your laptop’s battery is protected by a special circuit that protects it from overheating or even fire. However, the battery lasts much longer and needs to be replaced in less time.

How to recover Rapid battery discharge

It’s no fun running around looking for a power outlet that can work with your laptop. You want to be able to use your notebook in the subway, on the beach, or in a busy café without any problems, but the battery keeps running low. However, several solutions can help optimize the performance of your battery and ensure that it lasts a little longer and doesn’t run down quickly.

1. Using the battery

Check the battery slide to adjust the battery power. You can select the best performance, which does not affect the background applications at startup. However, the best battery operation mode takes precedence over efficiency.

Battery Saver mode prevents rapid battery discharge by reducing screen brightness and stopping background applications. At the same time, it prevents automatic Windows updates and prevents synchronization of the email application, which prolongs your battery life.

Energy-saving mode

If you have a Mac laptop, you’ll need to activate several options on the Battery tab, such as B. If possible, put the hard drives to sleep, avoid running unnecessary applications, or reduce the brightness when using the battery. Switching on the Power Nap or Better Battery mode is generally more useful than permanently switching on the Power Nap or Better Battery mode. This is because it prevents useful functions from being switched on.

2. Changing the display parameters

The brightest display option is not always the best. However, you can adjust the brightness until you reach a balance between extreme brightness and exceptional low light, so the battery lasts longer. What’s more, the low brightness means you can work longer on your laptop without tiring your eyes.

3. Turn off the keypad backlight

You can also turn off the keyboard backlight if you don’t need it. Although it can be extremely useful in low light conditions, you do not always need this light. At the same time, you can select an option that turns off the keyboard backlight after the notebook has not been used for a certain time.

4. Check the performance parameters

Check the latest changes you’ve made to your laptop’s performance settings, which can cause your laptop’s battery to discharge too quickly. You can choose to turn off the screen after a certain period or even turn off the notebook after it has not been used for a certain period. The battery will be stretched unnecessarily if you leave your laptop at rest. In addition, you can draw up an individual nutrition plan that meets your personal needs.

5. Close background applications

If you check your task manager, you can identify all applications and programs running in the background. Some are not needed, so they have to be stopped because they put a lot of pressure on your battery, which will discharge prematurely.

Background applications include alarm, note, photo, and memory applications. You can disable the entire application function in the background or enable or disable multiple applications in the background as desired.

6. Minimize network connections

Too many devices or networks connected to the notebook can cause the battery to charge. Therefore, you should check your settings and disable or prevent unnecessary network connections.

If you’re not in an area where Wi-Fi is available, or if you don’t need to go online, you can turn off the Wi-Fi setting because your laptop keeps searching for an available network, which puts a huge strain on the battery. The same applies to Bluetooth; if you are not currently using Bluetooth, you must turn off the Bluetooth function.

At the same time, examine the devices connected to your laptop and remove those that are not needed. These include USB devices, a wireless mouse, and Bluetooth speakers. Then, go to the taskbar and click to remove the unwanted device safely. If too many devices are connected, the battery will quickly discharge and eventually fail.

7. Remove the disc

An unused but connected CD or DVD should be disconnected to prevent the battery from discharging too quickly. The battery is required to power the player when not in use. Press the eject button and remove the disc to keep the battery charged.

8. Check the functions of your laptop

Your operating system may have attractive built-in features, but these features can consume too much power and are the reason you need to recharge them more often.

Windows 10 has some great features that help you use your notebook more efficiently, such as B. NET Framework 3.5, legacy components, Active Directory thin directory services, data center gateway, and containers. However, if these functions run continuously, you will probably notice that your battery will discharge too quickly.

If there is a feature you never use, you can delete it by clicking System in the Settings menu. You can also temporarily enable or disable these additional functions to extend battery life.

9. Selecting the sleeper instead of turning off 

If you close the laptop’s lid or leave it in sleep mode for a while, it will go into sleep mode. This power-saving mode allows you to resume your notebook’s functions quickly. However, even though it saves energy, it still uses battery power, even if you’re not really using a laptop.

The best option would be to hibernate. This saves the time of the last session and turns off the laptop, saving battery life. Of course, restarting the laptop will take a little longer if you put it to sleep, but it will positively affect battery life.

10. Recharging

Lithium-ion batteries do not recharge, but it is recommended that you disconnect the battery from your laptop before it reaches 100%. In addition, please do not wait until the battery is fully discharged, as you should try to charge the battery before it reaches 3%. If the battery is not nickel-based, discharging the battery completely before connecting it for charging will adversely affect battery life.


It’s a pity that your laptop’s battery runs out too quickly. If the battery is too old, it must be replaced. However, a few tips can help you prolong life a little.

Understand why the battery drains too quickly, and you can make some adjustments to solve the problem. Several solutions optimize your laptop’s battery for the most efficient performance.
