Is it bad to keep a laptop plugged in when it’s fully charged?

คำถาม
Keeping your laptop plugged into power when it’s fully charged will not make it overcharged as many might fear. ในความเป็นจริง, you need not worry as long as your laptop battery is lithium-based, it can’t be overcharged. The internal hardware components of the Laptop prevents the battery from charging until the voltage drops below 100%.

อย่างไรก็ตาม, it is important to note that charging the battery to high voltage (except for the first time) can significantly reduce battery life. According to some studies, charging the battery to only 85% ถึง 90% can improve its discharge cycle from 300 to even 1000 additional charges. โดยทั่วไป, if you charge a laptop to 85%-90% แทน 100%, the battery life could increase by 6 months to a year. มีอะไรอีก, charging the battery to only 70%-75% can almost quadruple the discharge cycle.

What’s the science behind this?

Technically, it takes more computer power to fill the last 3% of your batteryyour battery only has so much reserve where it can squeeze out electricity, so it requires a lot of energy to move the charges around to accommodate the final 3%. This will usually make a difference in the life of your battery, but obviously not the charge level.
The downside is that if you don’t charge your laptop 100%, you will have less available battery life and your laptop will shut down after a shorter period of time. If you are constantly using your laptop away from the charging station, this could be a real problem for you.
แน่นอน, you can always get around this by using a laptop power bank. A power bank is basically an external battery that you can plug into your computer to recharge your battery-you don’t even have to plug your power bank into an outlet. When you’re using your laptop in the field and you need to recharge, you can simply plug in your power bank and recharge your power bank to about 80%. This will also allow you to buy a less expensive power bank that holds a lower voltage.
