Many users have the habit of charging their laptops continuously throughout the day, regardless of whether working, watching movies or studying online.
Some even rarely remove the charger from the device. This has led many to question, "Is such a continuous charge harmful to the battery? ".
According to computer experts, the answer is not completely simple, because it depends on how you use it and the operating environment of the device.
Modern laptops have become smarter in battery protection
Most laptop computers today are designed to automatically stop charging when the battery reaches 100%, so there is no overload like in previous generations of devices.
This helps to connect the charger continuously without causing immediate damage. However, that does not mean that the battery will be immune to wear and tear.
lithium-ion batteries are a popular type in laptops, which tend to deteriorate over time. According to studies, including a report in the journal Physical Chemistry Chemical Physics, the battery ages faster when it is simultaneously affected by high voltage and high temperatures.
Therefore, maintaining a 100% charging rate for a long time can promote this natural decline.
Temperature is the number one enemy of batteries
Temperature directly affects the rate of aging. When placing a laptop on a bed, blanket or thigh, the heat is retained, causing the battery to stay hot. The higher the temperature, the faster the damage to the battery.
Heavy tasks such as playing games, editing videos or rendering also make the machine hotter. If you connect the charger while increasing the heat, the battery will have to endure double pressure, thereby reducing durability.
Experts recommend that users should keep the device airy, place it on a flat and hard surface to minimize heat loss.
Ideal battery level is 4080%
Many manufacturers are equipped with a battery protection or battery care mode, limiting the maximum charging limit to prolong life.
Users can turn on this mode when working hours at the table. Occasionally recharging or releasing the battery lightly may be helpful, but it is not mandatory if the device is often running a direct power source.
When is it safe to connect to a charger continuously?
In activities such as office work, video calling, programming or design, continuous charging does not cause significant impact, as long as the air conditioner and ventilation port are not covered.
Conversely, when used on soft surfaces or in hot environments, continuous charging can speed up the battery aging rate.
Some notes to protect the battery when charging regularly:
- Place the machine on a hard, airy surface.
- turn on the battery protection or save the battery when available.
- Avoid playing games or running heavy duty when the machine is placed on a soft surface.
Keep the ventilation department clean.
- Do not store or leave the device idle when the battery is 100% full for a long time.
Running your laptop charging continuously is not a bad habit if you can control the heat and charging factor.
With the improvement of battery technology and energy management systems, users can completely use laptops all day without significantly affecting battery life, as long as the operating environment is maintained.
