Should Continuous Charging Plug For Your Laptop?

This is probably the question that any laptop user set out in the process of using.
The battery on the laptop can not continue charging when it is full

It is important to understand how Lithium-ion (Li-ion) batteries work and Lithium polymer (LiPo) standard on modern equipment.Many conflicting questions and advice are given.
According to How-To Geek These batteries cannot continue charging when full. When fully charged, the charger will stop charging until the battery level drops to a certain amount to continue charging. So no matter if broken laptop battery plugged in too long.

Battery life will definitely decrease over time
The longer the battery charge cycles, the lower the battery life.Different types of batteries have different charging cycles, Usually about 500 times.
That does not mean that the battery should be discharged from charging. Keeping a high-capacity battery is not always good. On the other hand, frequent use of battery power is not good either, Keeping the battery at a perfect 50% capacity is not very feasible either. Also, be aware that higher temperatures also reduce the battery life. Do not use your laptop for long periods of time, It is best to leave the battery in a cool place, about 50% capacity.

If possible, remove the battery to avoid overheating
Temperature affects a lot of battery life If you plan to always plug the charger for your laptop (and the power at home is always stable), remove the battery and store in a cool place so that the battery is not exposed to any heat.
However, if your computer is not overheating, this does not have much effect addition, many laptops now do not remove the battery so this way is no longer meaning.

Should I plug the charger continuously?

It is difficult to accurately answer this question, keeping the battery at 100% is not good either, charging and discharging many times is not good either.Basically, Despite doing what, laptop battery life is still being reduced over time.That's how the battery works So there will be another question: How to keep battery life as long as possible?

Computer manufacturers have guidelines, some recommend that plugging the charger continuously for the computer when not moving would be better, some are the opposite but there is no obvious reason.
Apple advised the MacBooks to charge and discharge their laptops at least once a month, but now they do not recommend it anymore.So, there really is not a satisfactory answer.

Occasionally withdraw the charger and plug charger can help "calibration" pin (Calibrate)
Sometimes charging, discharging the laptop battery can help to calibrate the battery. This ensures that the device always knows the correct battery capacity and gives you approximate time. In other words, if the battery is not calibrated, Windows may think its battery life is 20% but it actually does not have anything and the laptop will shut down without any warning.

By completely discharging the laptop battery and recharging it, the circuit on the battery can know how much energy is left.
In fact, Apple said the calibration is no longer needed with the new MacBooks.Calibration does not increase the battery life,It just ensures that the computer can know exactly how much battery life is left.This may be the reason why you do not plug in your laptop.
Laptop batteries cannot be immortal, No matter what you do to protect it, its power and life expectancy will decrease over time
