Myth vs. Reality


Using a laptop while charging can damage the battery and reduce its lifespan.


Modern laptops are designed to be used while charging without significant harm to the battery. They utilize lithium-ion batteries that are less prone to the “memory effect” and can handle charging and discharging cycles efficiently.


Charging and using the laptop simultaneously will generate excessive heat and harm the system.


While some heat may be generated, reputable laptop manufacturers have integrated efficient cooling systems to dissipate heat effectively. Using your laptop while charging should not cause any major overheating issues.

So is it safe to use the laptop while keeping it plugged in when the battery is already at 100%?


Keeping your laptop constantly plugged in and charging, even when the battery is at 100%, will significantly reduce its lifespan and also unsafe to be used.


While it is safe to use your laptop while keeping it plugged in and charging when the battery is already at 100%, doing so for extended periods can contribute to long-term battery degradation. To optimize battery longevity, it’s recommended to unplug the laptop occasionally and let the battery discharge to around 80% before plugging it in again.
