Η battery is one of the most important parts of a laptop, but we often do not pay enough attention to it. One of the most common questions asked by users for her is whether they should have her device constantly plugged in? Or if they have to wait until the battery runs out to connect it to the charger?
To answer these questions, we first need to better understand how a battery works computer.
Most laptop batteries are either lithium ion or polymer lithium ion. These batteries are designed to withstand many charging cycles. They can not be overloaded, which means that once they are 100% charged, they stop charging. They stop receiving energy, which is bypassed directly in the power supply of the laptop. Therefore, having it connected charger it will not damage your battery or cause a significant difference in the total battery life. But there are other critical factors that can affect it.
One thing to keep in mind is that there are some good practices that extend the life of your laptop battery. Each battery has a certain number of charge cycles, so recharging your battery repeatedly will ultimately damage its lifespan.
However, the most critical factor that can affect the life of a battery is overheating. Keeping your laptop permanently connected will not damage its battery, but you should also be aware of overheating caused by your laptop hardware.
Therefore, if the CPU / HDD temperature of your laptop is around 40ºC and you want to make extensive use of laptop then it is advisable to remove the battery from the device.
What do we need to do to improve battery life?
Since not all laptops have removable batteries, there is a simple method that can help you extend your battery life in a different way. According to tests performed by Battery University, a battery that charges at 100 percent, will only have 300-500 recharge cycles. On the other hand, if it is charged up to 70-80%, it can reach 1000-2000 recharge cycles.
Avoid completely unloading your laptop after charging. The best thing you can do is try to keep the battery level between 40% and 80%.
Make sure your laptop does not overheat and that the cooling fan is working properly.
Remember that your laptop battery can not be "overcharged" and damaged due to overcharging. It is smart enough to bypass the charging energy.
