Can you keep the laptop plugged in?

Can a laptop always be plugged in?

Some people use laptops in the office or at home all year round, with the computer constantly plugged in and the battery level maintained at 100%. One thing to worry about when doing this is that keeping the lithium battery fully charged for a long time may cause battery passivation and affect battery capacity.

So for friends who always plug their laptops in, our suggestion is to occasionally unplug the power and use the battery. After all, you cannot guarantee that there will always be a power source available. Maintaining the battery will prolong its lifespan. Remember to plug it back in promptly, otherwise it may suddenly run out of power and shut down, and any unsaved items may be lost.

Can I turn off my computer when it runs out of battery?


Most laptops nowadays use lithium batteries, and some people worry that deep or even excessive discharge of the battery may irreversibly damage it. Although there is some truth to this concern, there is no need to worry too much. Manufacturers usually design battery management systems, so that when your computer runs out of battery, it does not actually reach the level of deep discharge. In summary, let's charge it when it's convenient.

Can the computer be stored for a long time?


Some people may not use laptops frequently or have a backup computer. When these laptops are stored for a long time, in order to protect the battery, it is best to keep the battery level at around 50% before shutting down, not too full or too low.

Even if you shut down, the battery will still discharge secretly. So if you store the device for a long time when the battery is completely depleted, the battery may discharge deeply, leading to structural damage. Recharging at this point may not be possible!

On the contrary, if fully charged devices are stored for a long time, it may damage the battery and reduce its capacity.

If you plan to keep your computer for more than 6 months, it's best to charge it to 50% every 6 months.

The most important thing is to maintain the temperature!


For lithium batteries, what is truly enough to destroy them is high temperature.

Try not to use your laptop on things such as blankets or pillows that may block the heat dissipation holes, and do not use it in high temperature places year-round.

Apple's suggestion for this is to avoid placing devices in environments with temperatures above 35 ° C, as this may permanently damage the battery capacity.

Actually, there's no need to be so nervous


In fact, manufacturers have been updating and adjusting according to user habits for so many years, such as adding overcharge and discharge protection functions for batteries, which is not so easy to cause serious damage to laptop batteries. In this era of rapid electronic product updates, the breakdown of batteries and the replacement of a new computer may not necessarily happen faster.

As long as you don't let the laptop battery be damaged by high temperature and water, and based on your original usage habits, pay a little attention to the above matters, it is probably enough.
