Much more than just another home appliance, laptops are the main work and study tool for many people. Especially in post-pandemic periods when remote working has become so common.


Therefore, due to the frequent and constant use that many owners give to their devices, many users leave their laptop connected to electricity throughout the day. This is to prevent a possible download in the middle of an important work, student, or personal task.

But tech experts agree on this: Leaving the computer connected all day, even if the battery level has reached 100 percent, may have adverse effects. We tell you why.

First of all, to put the myths to rest, the technological portal ‘Hard Zone’ makes it clear that: the problem is not due to potential overcharging of the battery. In fact, protection mechanisms in modern laptops are specifically designed to stop the flow of available power when the battery reaches 100 percent, so as long as the system is running, there’s no possibility of overload.

The portal adds: A laptop’s battery will always get weak over time, whether it’s left plugged in or not, or even if it’s not being used.. This comes from design, programming and its own lifespan.

As mentioned above, the battery will always fail. However, it is important to look for ways to slow down this process and avoid practices that will lead to failure.

It is worth remembering that manufacturers are constantly implementing improvements in their new versions to reduce the number of problems, and as the specialized magazine ‘PC World’ notes, most modern computers detect when the battery does not need more energy, detecting when it does not need more energy. Capacity to use the outlet as a power source and not as an internal battery.

However, even in these models Leaving devices plugged in causes premature aging of lithium batteries. In fact, some of the most important manufacturers on the market, such as Acer or Apple, recommend avoiding this practice in their user manuals.

Continuous exposure to high voltage causes lithium batteries to age very prematurely.. ‘PC World’ explains that for every percentage of the battery in the computer, the voltage on the energy storage also increases, which affects the chemical components of the hardware.

This aging occurs at any time of battery usage, but is particularly high at high and low voltages, i.e. below 30 percent and above 70 percent. This means that The problem is not the regular flow of energy, but the high charge. The same applies to mobile phones, for example.

NO. An on and off cycle is usually recommended to keep the battery charge between 30 and 70, but this is, in addition to being quite tedious, constant heat generation due to the start of the charging process, which seriously affects the service life of the device.
