By | April 26, 2023

It’s likely that, if you’re like the majority of people who use laptops, you spend a significant amount of time with your device hooked to a power outlet. After all, it is helpful to be able to work without having to worry about the remaining charge in your battery. You may have heard, on the other hand, that leaving your laptop plugged in all the time is detrimental to the battery life of the laptop. In this essay, we will investigate whether or not this claim contains any kernels of truth, as well as what you can do to maintain the health and durability of your laptop.

The Fallacy Behind the Memory of Batteries

The phenomenon known as “battery memory” is one of the primary reasons why people have the misconception that constantly connecting their laptop to an external power source is detrimental to its internal battery. Memory effect was a problem that used to happen with older rechargeable batteries, which would “remember” how much charge they had and lose capacity over time if they were only partially charged. Modern rechargeable batteries do not have this problem. Nevertheless, brand-new batteries designed for laptops do not have this issue.

Modern Lithium-ion Batteries

The majority of today’s laptops are powered by lithium-ion batteries, which can withstand being connected to an external power source for extended periods of time. These batteries come pre-fitted with charge controllers that prevent the battery from being overcharged and shut off the charging process once it has reached capacity. To put it another way, once the battery of your laptop has reached its maximum capacity, it will not continue to charge and it will not be harmed if you leave it plugged in.

Advantages of Always Having Your Laptop Connected to Power

In point of fact, there are a few advantages to always having an electrical connection to your laptop. When your laptop is plugged in, it receives power from a source that is constant and stable. This can assist to reduce the number of unexpected shutdowns that occur and can improve its overall performance. In addition, if you are working on activities that take a lot of power, such as editing videos or playing video games, your laptop might not be able to keep up with your demands if it is only powered by its battery and not connected to an external power source.

How to Ensure the Long-Term Vitality of Your Laptop’s Battery

There are a few things you can do to ensure the continued good health of your laptop battery, even if it won’t do any harm to the battery even if you leave it plugged in all the time. One strategy for achieving this goal is to prevent letting the battery of your laptop go fully down before recharging it. Because lithium-ion batteries don’t like to have their charge totally drained, it’s ideal to recharge your battery before it comes to a point where it can’t be charged any further.

In addition to this, it is recommended that you make use of your laptop’s battery on a regular basis so that it remains operational. If you usually have your laptop plugged in, the battery may go unused for extended periods of time, which can cause it to degrade over time. This can be avoided by keeping your laptop unplugged when it is not in use. To avoid this problem, you should occasionally disconnect your laptop from its power source and run it off of its battery instead.

In conclusion, the ideal way to store your laptop if you are going to be putting it away for a lengthy period of time is to do it when the battery is still partially charged. When you put your laptop away for an extended period of time, the battery should ideally be charged to somewhere between 50 and 50 percent of its maximum capacity. This will assist to keep the battery from degrading over time.


There is no risk to the battery life of your laptop if you always have it plugged in, but there are some other things you can do to keep the battery in good condition and extend its useful life. You can help guarantee that the battery in your laptop remains in good health and lasts as long as possible by avoiding entirely depleting the battery, using it occasionally, and keeping it with a half charge. This will help the battery last as long as possible. In the end, selecting the optimal configuration for your particular usage of the laptop and requirements is what matters the most.
