Should I Leave My Laptop Plugged In And Charging

Most things will only do one thing well at a time. When you charge and use the battery simultaneously, the battery must both discharge and add energy.

This means you force the battery to do two things at once, and it has to increase its productivity. If this continues for a long time, it will affect performance, even circuit failure, and battery failure.

The laptop has a compact design so you can take it anywhere. Constantly plugging in the charger means you deny its convenience and portability.

Over time, the battery will lose its ability to store energy, and you will not be able to continue using the laptop without a power source.

This will be no different than using a desktop computer, and even the functionality is not equal. You can learn more about the harmful effects of constantly plugging in a laptop charger in this video.

Some Factors Affect The Battery

Things That Affect The Battery

Laptop users will want their machine to last for a long time. However, it is also necessary to know the causes or effects that adversely affect the battery to preserve it.

When we know those bad effects, we will find solutions to solve that problem.

Charging cycle and battery usage

The battery will wear out after each charge and use cycle. So you need to minimize the time between cycles so that the battery can last longer.

You need to avoid using the battery completely because it is possible that "deep discharge" will occur, and the power cannot be reconnected.


Voltage determines a lot of battery life. You need to carefully research how much power your laptop or charger accepts to use the proper power supply.

Many people think that the higher the voltage, the faster the charge, but using the wrong power source will shorten the battery’s life.


Numerous tests have confirmed that high temperatures negatively affect the laptop's battery.

You should maintain and make sure the battery stays within 30 degrees. If this number is larger, it will cause more damage to your battery.

Also, according to this study, high temperatures will consume more energy for the device to be used normally.

Over time, the battery’s maximum capacity will decrease and only about 65% of its original level after one year. If the temperature is too high, it will also be dangerous and lead to cases such as fire or explosion.

How To Extend Battery Life

How To Extend Laptop Battery Life

The article will also mention some ways for you to preserve and maintain the battery’s life longer. So stay tuned to the end of the article to ensure you don't miss any interesting information.

The laptop is an item that you will use for a long time. The battery is one of the important factors, deciding whether the device can continue to be used or not.

If your battery malfunctions or needs to be replaced, it will cost a small amount of money. So how to extend battery life is an issue that many people are interested in.

For laptops with removable batteries

Removing the battery is one of the methods to increase the life of your laptop.

Temperature is a factor that adversely affects the performance of the machine. So removing the battery after use with high performance is a way to help the device dissipate heat better.

Even when you are not using the device, you can also remove the battery to let it rest. Not at all, but some computers will still drain a small amount of battery even if you don't power on the laptop.

For laptops with a unibody battery design

Today, most manufacturers mold the battery with the machine into a block to meet the needs of "thin," "light" users. So, you will not apply the above method of removing the battery with modern laptops.

However, there is still a way for you to increase the life of your battery by using the 20-80 charging method.

Some studies have shown that fully charging the battery to 100% and using the battery to the end is not beneficial for the laptop.

So, you should only charge to about 80% and continue to connect the power source when the device reaches 20% battery.

Timing to charge to a certain extent is not easy. However, for the battery and laptop to be used for many years, you cannot ignore this tip. A little trick to help you time more accurately is to time the charge from 20% to 80% the first time.

Once you know how long it will take to charge to that level, you can set the timer to automatically disconnect the charge or go back to manually unplugging it.


Surely after reading the above information, you will still be confused and ask yourself many questions. So we've put together the most frequently asked questions here to answer your questions.

What will happen if the laptop is plugged in continuously?

Continuously plugging in a laptop charger can be divided into two cases: with power connection and power disconnection. This is completely normal in the absence of current, and you do not need to worry about what will happen.

And if you plug in the charger continuously and have a power connection, it is bad for the laptop. Some people think that constantly plugging in the charger will help the device work for a longer time. 

However, the result is the battery in your laptop, and the machine will run out of battery faster. In the long run, this action will damage the battery, which can not accept more energy.

How to check battery quality?

How to check battery quality?

Checking the quality of the battery is a way to help you make sure it's time to replace a new battery pack or not.

This process may take some time, but it will detail your current battery health. You will also easily control the battery-intensive actions or background applications to handle it.

This tool is available on most computer lines without you having to install it outside.

  • Enter “CMD” command on Windows startup

  • Select “Command Prompt” and run as administrator

  • Wait for the software to run and continue to enter the command “power” in the display.

  • After entering the above command, the computer will automatically calculate and return the result to you. You can directly refer to these figures and develop a reasonable way to use the laptop yourself.

Under what circumstances is it allowed to charge continuously?

Constantly plugging in the charger is not advisable, but there are some exceptions. One of the cases where you need to be constantly plugged in is gaming laptops. 

These gaming laptops have their design and allow continuous charging when in use to maximize machine performance. However, you should only do this when you need the machine to operate at high capacity.

Many people often plug in the charger continuously, even with old laptops, and cannot be used without a power source. 

However, this is not advisable. You should invest some money to replace the new battery. This replacement can cost you a lot but will save you money later on.

How do I stop laptop batteries from charging when plugged in?

There are many reasons why people don't remove the charging cord from their computer. One of them may be because connecting the charging cord is difficult, or people want to be more convenient the next time they plug in the charger.

The continuous charging connection is not good for the battery and will reduce the laptop’s performance. So one solution is to disconnect the charger and keep it plugged in.

You can find this function under “Power Manager Lite” in the settings and choose to stop charging. 

However, not all laptops have this function. Some manufacturers leave this function in another section, and you need to find it in your laptop.


Everything will wear out and deteriorate over time. Batteries are products that people use regularly, so they will also wear out according to a certain rule.

In addition to external forces, the battery will wear out according to the charging cycle. Simply put, the more you charge, the faster the battery will fail. So you need to balance between usage time and recharge the battery.

If you always plug in the laptop battery charger constantly, change it now to protect your laptop. Please share the article with your friends to help them use their laptops more properly.
