Should You Always Keep Your Laptop Connected?


Is it better to keep your laptop connected or use it on battery power gets up reply isn’t entirely straightforward?


At one point or another, all laptop users find themselves pondering the same question: is it poor to leave your laptop connected all the time? So let’s take a look.

Know Your Laptop Battery connected

There are two main types of batteries used in laptops. Lithium-ion and lithium-polymer. Because Although they are different technologies, they function in broadly the same way, generating power through the movement of electrons. This constant flow is also needed to help keep the battery healthy.

It is impossible to overcharge a battery. There’s no danger of overcharging a cell if you leave it plugged in all the time. As soon as it hits 100 percent, it will cease charging and won’t start again until the heat falls below a certain level.

Fully discharging a battery will damage it.

Allowing the battery to become empty for an enlarged period can put it into a deep discharge state. It can be fatal—you might never be able to charge it again. (You can try these methods to jump-start a dead laptop battery.)

So, based on this, do we conclude that you should leave your laptop plugged in all the time? Not quite.

Things That Damage Lithium Batteries

The truth about lithium-based batteries is that they are naturally insecure and They begin to lose capacity as soon as they make numerous factors hasten their decline. These numbers

Charge/discharge cycles

Every battery has a fixed number of times it can be charged and discharged.

Voltage level

The higher the charge level (measured in volts per cell), the shorter the battery’s life.

High temperature, over 30 degrees celsius

It can cause irreparable damage.

The last two are the ones that we’re most concerned with here. A complete study by Battery University highlights how voltage levels and high temperatures will shorten the life of a battery in isolation and even more when combined.    

Charge or Voltage Level   

Lithium-ion batteries charge 4.20 volts per cell. It’s the full extent of their skill.

And then there’s heat or High temperatures, typically classified as being over 30 degrees Celsius, which will shorten the life of a battery irrespective of any other factors.

The Battery University study shows that a battery stored with a 40 percent charge at 40 degrees would see its capacity fall to 85 percent next years.

Under the same conditions, the capacity drops to 65 percent when fully charged.

In just three months, the size of a fully charged battery at 60 degrees drops to 60%.

Keeping the battery charged indefinitely at 100 percent will slowly shorten its life and Keeping it at 100 percent and display. its high temperatures will shorten it much quicker.

And remember but these high temperatures are not just environmental.

Resource-intensive tasks such as gaming or video editing will greatly increase heat levels,

 and using the laptop on a pillow or in a poorly designed case will trap that heat is good. For the aim of your battery, it’s always a good idea to fix an overheating laptop.
