Which is better, letting the laptop charge continuously while using it or only charging it when it’s low? This matter often causes debate.
Some argue that using a laptop while charging will make the laptop battery last longer. There are also those who say that we should unplug the charger when the battery is full and plug it in again when the battery is low.
Some even suggest removing the laptop battery when in use. Even though actions like this can cause damage to the laptop, it can even damage the laptop battery itself because it is often removed and installed continuously. Things like this can cause damage starting from the battery, HDD/SSD to the laptop motherboard because the current on the charger is unstable.
To answer this question, let’s look at the following reviews
New Laptop is Safe to Charge While Using.
Using a laptop while charging it continuously was not a wise move a few years or a decade ago. However, along with the development of technology, this is not a big problem if done for now.
Now, the majority of new laptops are equipped with lithium-polymer or lithium-ion batteries. Both are able to stop the charging process when the battery is full. So, you don’t need to be afraid of the risk of overcharging or overcharging.
You must be aware of the risk of the laptop getting hot
The question that arises is where does the electricity that goes into the laptop through the charger if the battery doesn’t suck its power? Apparently, the electricity does not pass through the battery, but directly provides power to the laptop. This then becomes a problem.
Still from the same source, electricity that continues to flow will produce excess heat. As a result, the laptop experiences overheating or the temperature becomes too high. This condition will not have a direct impact. But if this happens continuously in the long term, the battery function will decrease.
Do not continue to charge when the battery is full
Research from Battery University says that leaving the charger plugged in when the battery has reached 100 percent can make it strain and go the extra mile. This will make the function of the chemicals in the battery decrease.
Therefore, the researchers suggest that we immediately unplug the charger when the battery is full. They say it works like relaxation after a strenuous job.
Don’t Charge To 100 Percent
We should not charge the battery to 100 percent, because the lithium-ion type laptop battery does not need to be fully charged because the high voltage will make it “stressed”.
This is the same as written in the journal IEEE Xplore. Researchers suggest that we unplug the charger when the battery is 75 percent charged. Then charge it again when the battery is used up to 20-25 percent. This method will maximize the capacity of the laptop battery.
Decreasing With Use However, you should know that laptop battery life inevitably decreases with use. This is a natural thing and will definitely happen to all electronic devices, not only laptops. If you’ve been wearing it for several years, don’t expect it to last as long as it did when you bought it.
The thing you can do to slow down the process is to apply the charging method recommended above. In addition, as much as possible do not let the laptop battery completely run out to 0 percent. This will speed up the decline in functionality.
The conclusion is, leaving or using the laptop in a continuously charged condition is not dangerous for the user or the laptop battery, with a note not to let the laptop’s temperature condition get too hot. During normal use of the laptop, the battery life will last longer when the laptop is used while charging. After all, the latest laptops now have an auto cut off power feature, so the electric power from the charger is automatically cut off when the battery is fully charged.
