Proper use of a laptop battery: is it safe to always keep it charging?

Among modern users, the question “Is it possible to always keep a laptop charging?” is frequently discussed, reports lifehacker.ru. Most people believe that using a computer connected to the power grid for a long time negatively affects the battery, and this stereotype still persists. However, given today's technology, this question should be approached differently.

New generation laptops have an automatic charge control system: once the battery is fully charged, the device receives power directly from the mains, and the battery is not under unnecessary load. This prevents battery wear and loss of capacity. Previously, such features were found only in high-end devices, but now Lenovo, Asus, Dell, HP, and other leading brands offer this as standard.

At the same time, the biggest risk for users is the overheating of the laptop. If you work under high loads (for example, video editing or gaming), the battery is constantly exposed to heat. Lithium-ion batteries do not tolerate high temperatures: even air at 40–45°C gradually reduces battery life. Therefore, the best advice is to use the laptop in a well-ventilated, shaded, and cool place.

Another important point is the activity of using the battery. If you use the laptop only from the power grid and the battery is always at 100%, the internal chemical processes in the battery cause it to gradually lose its properties. Therefore, it is necessary to discharge the battery to 30–50% once or twice a week and then recharge it.

Manufacturers have also created special software to protect the battery. For example, applications such as Lenovo Vantage, Asus Battery Health Charging, Dell Power Manager limit the battery charge to 60–80%. This is especially convenient for users who always use their laptops plugged in at home or work.

In conclusion:
If your laptop does not start to overheat and you use the battery independently at least once a week, it is considered safe to keep a modern laptop always charging. The most important thing is to learn proper usage habits and follow your device's technical recommendations. Read 'Zamin' on Telegram!
