Is it fine to keep my laptop always plugged in to maintain a full 100% battery?
Is it necessary to let it discharge sometimes by unplugging to extend the battery's lifespan?
Most laptops nowadays use either lithium-ion or lithium-polymer batteries, both of which have a limited number of charge and discharge cycles. Some people worry that consistently charging the battery, especially while using the laptop, might negatively impact its health.
The truth is, this concern is not entirely accurate. When your battery reaches 100% charge, the laptop's charging system usually bypasses the battery and directly powers the laptop using the incoming electricity. This is similar to running the laptop without a battery while it's connected to a power source.
In fact, you don't need to deliberately drain your battery regularly. In fact, doing so can have the opposite effect of what is intended. Modern batteries are designed to handle the daily charging and usage patterns of most people without needing to be fully discharged.
No matter what you decide to do, the difference in the overall lifespan of similar laptop batteries, whether you keep them plugged in or not, is generally minimal – around 8 to 10 months at most, depending on how you use the laptop.
Here's an important point to remember: overheating can significantly reduce your battery's lifespan. High temperatures are a major factor in battery deterioration. To prevent this, consider using an external cooling pad while you work. Brands like Cooler Master offer effective cooling pads that can help maintain your laptop's temperature and prolong its battery life.
So, in conclusion, feel free to keep your laptop plugged in as needed. You don't need to obsess over discharging it regularly. Just be mindful of temperature – keeping your laptop cool can do wonders for your battery's longevity.
