Have you ever worried about the battery life when using a laptop? Can it be used with the power supply plugged in all the time? Do I need to use up the battery before charging? How can batteries be used to ensure their lifespan?

Today, let's answer everyone's questions one by one!

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

Most laptops nowadays use lithium batteries, and some friends may worry that deep or even excessive discharge will irretrievably damage the battery. In fact, there is a certain reason for this concern, but you should not be too careful not to use the battery. The manufacturer usually designs a Battery management system, so that when your computer is out of power, it does not actually reach the level of deep discharge.

In summary, let's charge it when it's convenient to charge.

Can 02 store the computer for a long time?

Some friends 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 turn it off, the battery will still "secretly" self discharge. So if you store the device for a long time while the battery is completely depleted, the battery may experience deep discharge, leading to structural damage. Recharging at this point may not be possible!

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

If you plan to keep your computer in dust for more than 6 months, it's best to take it out every 6 months to wipe and charge it to 50%.

Can you keep plugging in the laptop at 03?

Some friends 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 plug laptops in all year round, our suggestion is to unplug them and use the battery whenever you want to occasionally remember. After all, you cannot guarantee that there will always be a power supply available, so maintaining the battery life slightly is safer. Remember to plug it back in in a timely manner, otherwise it will suddenly run out of power and shut down, causing disaster for things that have not been saved.

Structure of lithium batteries

The most important thing is to maintain the temperature!

For lithium batteries, the damage caused by the previous improper operation is Drizzle compared with the high temperature. What is truly enough to destroy batteries is the high temperature.

Try not to use your laptop on blankets, pillows, or other items that may block the heat dissipation holes, and do not use it in hot places all year round.

05 Actually, there's no need to be so nervous

In fact, manufacturers have been updating and adjusting according to users' usage habits for many years, such as overcharging and discharging protection, which is not so easy to cause serious damage to laptop batteries. In this era of rapid electronic product updates, whether the battery crashes or you replace a computer, it's uncertain which one will arrive in advance.

As long as you don't let the battery be persecuted by high temperatures and water ingress, and based on your original usage habits, paying a little attention to the above matters is probably enough.
