Using a laptop while charging is a common behavior among users, in this article we will check whether working with a laptop while charging is harmful to the health of the battery or not?
Today, technology plays a very important role in our lives and we all keep our sensitive personal, work, academic, etc. information on our laptops, tablets, computers or smartphones. For this reason, it is very important to know the solutions to increase the efficiency, durability, longevity and safety of these devices.
Many people spend a lot of time outside the home and laptops have become an integral part of their work and education. The use of a laptop depends on its battery being charged, unless we want to use the laptop while it is charging. This is the situation that all the people who have a laptop have faced and at this time a question occupies their mind, is it right to use the laptop while charging? Will this damage the laptop or battery? Should we charge the battery and then use the battery charger or remove the battery from the circuit and plug in the laptop directly? Which solution is correct?
In this article, we want to talk about using a laptop while charging and remind you of ways to increase the battery life of a laptop, so if you have a laptop, stay with us until the end of the article.
In the past, laptop manufacturers emphasized that we should not work with the laptop while it is charging. This was the thinking that existed based on the technology of making laptops and its battery until about 5 or 6 years ago, but nowadays, the technology of making laptops and the quality of its batteries have improved significantly compared to the past, and manufacturers are less concerned about this issue.
Regarding connecting or not connecting the laptop charging cable, there is a difference of opinion among experts in this field, and it is not possible to give a definite opinion on whether or not it is safe to use a laptop while charging, or in simpler words, using a charging cable while working with a laptop in the same way. The model and manufacturing technology of the battery and its hardware are dependent, that’s why it is not possible to make a single version for all laptops on the market.
Charging cycle in laptop batteries
But if we want to give a general opinion, it is better not to work with it while charging the laptop (especially normal and cheap models). Today’s laptops use lithium-ion and lithium-polymer batteries that have charge cycles. This means that you can charge it a certain number of times and over time the capacity of these batteries will decrease and the charging capacity of the devices will decrease.
Of course, in newer models, this charging cycle has increased significantly and reached 300 to 500 cycles. In this way, your behavior should be different compared to the laptop you have. Companies such as HP and Asus have stated in their laptop descriptions that after one year of continuous use, their battery capacity will decrease to 80% of normal, but if you use the laptop heavily and continuously for two years, its battery capacity will decrease. It reaches less than 60% of the initial state. Continuous charging and discharging of the laptop battery reduces its lifespan. In old laptops that are several years old, this charging period is lower and it is better not to have the charging cable continuously connected to the battery while working.
Using a laptop while charging
If you have an old laptop, the battery is probably disconnected, so if you use the laptop continuously, remove the battery and plug it directly into the power supply. This is the best way to continuously and heavily use an old laptop.
In today’s smart laptops, when the laptop is connected to the power and the charging process reaches 100%, the charging current stops, but if you continue to use the laptop while charging, after a short period of time, the charging capacity of the laptop will be reduced and the charging current will start again. The battery starts charging until the small amount that the charge has decreased, it returns to the battery and the laptop charge reaches 100%, and when it reaches 100%, the charging flow stops again!
This incident and repeated cycle causes the battery and the device to heat up a lot, and as we know, heat is the enemy of electronic devices and especially batteries, and the charging cycle of the batteries ends earlier and the battery is damaged. In this way, in the new models, there are features and software with which the battery can be removed from the charging supply stream and directly connected to the city electricity.
Using gaming laptops while charging
But the case is different for today’s gaming laptops, gaming laptops need to be directly connected to power to run heavy games, that’s why they are designed in such a way that after the battery is charged, the battery is automatically disconnected and the system is turned off. It provides the required energy directly from electricity. This system is present in most gaming laptops and laptops that are made for design, and it prevents premature failure of the laptop battery.
What is the solution?
Energy Manager program in Lenovo laptops, ASUS Battery Health Charging program in Asus laptops and HP Peak Power Manager in HP laptops give users the ability to remove the battery from the circuit. But apart from that, in Windows 10, you can remove the battery from the circuit and directly connect the laptop to the power. To do this, right-click on the My Computer icon and select Manage. In the displayed window, select the Device Manager option, now you can see the list of all laptop hardware in the middle of the page. At the top of the page, open the Batteries option and click on the Microsoft ACPI-Compliant Control Method Battery option to disconnect the battery from the circuit, in this way the battery will be powered but the energy will not be transferred from the battery to the device.
Various laptop manufacturers have recommendations to protect the battery and increase its life:
If you want to not use the laptop battery for a while, charge it to about 50-60% capacity and then store it in an environment with normal temperature and not exposed to cold, heat or direct sunlight, the most suitable temperature for Laptop battery temperature is 10 to 35 degrees as recommended by Asus. Of course, in terms of temperature, HP emphasizes that the temperature of the battery should not exceed 40 degrees, and if not, the life cycle of the battery will decrease significantly.
Another point is to try not to use the battery for more than three months, that is, use the laptop battery for at least one day every two months and put it away again, in this way the battery will not be damaged even after several months. , its quality will have the least drop. Lenovo emphasizes that when updating Windows or other parts of the system, the battery should not be used in any other way.
Also, close unnecessary devices or functions while working, for example, if you are done with the external hard drive, disconnect it from the laptop, or if you are not using functions such as Bluetooth and Wi-Fi, disable them.
Most companies emphasize that you should not let your laptop battery charge go to zero and plug it in as soon as the laptop has 20% charge, and when the charge reaches 95%, disconnect the laptop from the charger and let the laptop charge only from the battery. to feed
final conclusion…
According to the above explanation, it is better not to connect your laptop to the electricity for a long time and do not use it while charging. If you can remove your laptop’s battery, do so and protect your laptop and battery according to the instructions above.
But if you can, software remove the battery from the circuit and use electricity directly. Of course, all these things are for when you intend to play games or use the laptop continuously. If you only use the laptop for a few minutes or a few hours a day, it is better to connect the battery and take advantage of the battery, also do not use the laptop while charging.
