Doubts about how to optimize the operation of a computer are quite common. One of the most frequently asked questions is: is it good to always have the laptop plugged in? What happens if I use my laptop connected to the power? The answer is not simple, because there are different opinions and, in addition, each manufacturer gives its own recommendations for use.
Currently, many people prefer a laptop to a desktop computer, due to the advantage of being able to carry it from one place to another. When they came on the market, that was their function, to be operational without electrical current, but it is becoming more and more common to use them as a fixed computer. It is then that the question arises, what is better, having the laptop plugged in or not? If this issue worries you, at One How to we explain the pros and cons of having your laptop always plugged in.
Is it good to have the laptop always connected to the power?
The first thing to know is that nowadays it is already difficult to find notebooks with a removable battery like the first ones to hit the market. The most common, currently, is to have a laptop with an integrated battery, which is quite difficult to remove. Therefore, it is normal to use the computer plugged in and with the battery installed. But is it good to have the laptop always plugged in?
In principle, using a laptop connected to the current is not a problem, because, despite what some statements claim, in reality, the battery is not overcharged. Current equipment has protection systems so that, once the battery is full, the charging process stops.
Current lithium-ion batteries work in such a way that they are only recharged when their charge level is not 100%, so having the laptop always connected does not imply any danger, nor does it mean that your battery will degrade. early. Even so, there are opinions that suggest that making the battery go through charge cycles every so often (causing it to discharge to recharge it later) can help extend its useful life.
How long does a Laptop battery last?
It is impossible to determine exactly how long your laptop battery will last, because its useful life depends on both the manufacturer and the computer model. Therefore, it is essential to know how to choose a good laptop. Also, the length of time the unplugged battery lasts depends on how you use the laptop. We must take into account its degree of wear, something that occurs progressively and is inevitable.
In general, the battery of a new laptop can last between 3 and 6 hours without depending on the electrical current, but it can be more or less hours depending on how you use the laptop. Another question is how many months (or years) can elapse before you detect that the laptop battery does not charge, perhaps due to a technical problem (bad connection) or perhaps because its useful life has ended.
In this sense, you have to understand how these batteries work. In any computer, they have a limited series of charge cycles, that is, they will be able to discharge and charge in their entirety a certain number of times, which usually ranges between 300 and 500 charges.
At the moment of truth, the battery usually lasts slightly less than what the manufacturers indicate. It is because, generally, the indicated duration does not contemplate real situations of misuse that can accelerate its deterioration. Current batteries last a minimum of 2 to 4 years, although that time can be much longer if we take care of the battery correctly.
How to take care of the laptop battery?
Now that you know that it is not a bad thing to have the laptop always plugged in, you can take a series of measures to extend the life of the laptop’s battery. Although it reduces its total capacity of charge as it “ages”, there are a number of tips that help prevent damage to the laptop battery, making it last longer in good condition.
- Whenever possible, activate the ‘economy mode’ when using the computer, whether it is plugged in or not.
- When not essential, reduce the brightness of the screen. That much brightness, which is not always required, also drains battery.
- Protects the laptop and its battery from high temperatures. The high heat, especially if it is coupled with ambient humidity conditions, can end up deteriorating the equipment and its battery.
- Don’t keep endless applications open if you’re not using them.
- Unless you expressly want to discharge your battery to restart a charging cycle, try, on a day-to-day basis, that it does not lower its charge level below 20%, that is, if you work with the laptop unplugged and see the ‘Low battery’ warning, connect it to the mains.
- Remember that, in principle, having the laptop always plugged in is not bad: what can be harmful to the battery is having it discharged for too long a period of time.
When a battery is damaged, you will notice that problems begin to appear, such as that the laptop battery does not charge or that the computer is not able to detect it.
