Is It Good To Use Laptop While Charging? – Truths You Must Know

Plenty of myths about this question abound, but the truth is, it’s perfectly fine and safe. Plenty of misinformation too- like thinking you need to unplug from power once the battery reaches 100%. There are lots of other things that people mistakenly believe about laptops- but they’re all wrong.

Actually, these days when laptops come with smarter Li-ion batteries, plugging in your laptop can actually give you some great performance benefits. There are barely any disadvantages at all.

Unlike their old nickel counterparts, the modern Li-ion batteries don’t sound off unless they are being partially recharged. However, you should never allow these laptops to go below 20% or 15% of battery life before recharging it again.

In short, it may be more beneficial for you to charge and use your laptop at the same time because doing so can allow you to make more money. Let’s dive into this topic below.

Is It Good to Use Laptop While Charging?

Well, as I mentioned before, it’s absolutely fine to use the laptop while it’s plugged in. Laptops today usually feature lithium ion batteries and most of them come with an internal charger which monitors how much power is left.

However, there is no way for the laptop to recharge its battery if it’s plugged in. The intelligent charging chip and the battery’s internal control system will stop sending power to the battery when it has reached 100%.

The battery will continue to stay uninterrupted from the power supply until it falls down below a certain charge level -usually 95%. When this happens, the electrical controller will start directing all of its power towards the battery until it starts running again.

Now, when one is connected to an external power source, the laptop continues running off of that external power and does not consume its battery. For this reason, even if it comes down to 95%, the battery will still remain stable due to having no stress put on it.

However, once it falls below that point, the power stops flowing again – stopping at 100% of its current charge. And as soon as this happens, so does the inflow of electricity cut off.

After discussing the topic Is It Good To Use Laptop While Charging, now we can go over the batteries while they are being charged.

So, Does the Use of Laptop While Charging Affect Battery Life and Performance?

Well, yes, it does affect the battery’s overall performance. However, there are many positives and only a few negatives about being plugged in all day for your laptop to charge efficiently.

And the first advantage of this laptop is that it helps your battery last longer because it cuts out the constant energy drain coming from a plugged-in power source. Besides, if you’re doing something more complicated such as playing games or running other heavy programs, keeping it plugged in will increase its performance too.

It would allow you to tweak the graphics settings. You could set it all the way up to what might seem unattainable if given an opportunity without this app at hand. The on-battery power is always less than when plugged in.

Furthermore, as I said in the introduction paragraph, if you want a lithium battery to work optimally, never let it completely die out.

Yeah, I said, those old nickel-clad batteries seemed to work well when we would recharge them only after they had been depleted. But this does not seem to hold true for lithium-ion batteries.

According to Battery University (a battery information website that knows all things about batteries), the only way to prolong a lithium-ion battery’s life is to charge it regularly. Regularly discharging it until it’s completely drained of power is not good for a Li-ion battery.

Anyways, it doesn’t mean that you should stay plugged in all day long. Yeah, although hard to resist at times, there are some disadvantages too.

Should You Keep Your Laptop Plugged-in (Even at 100% Charge) All the Time? Is It Good or Bad?

It seems like keeping your battery filled at all times would be an easy task – but it does come with risks for the battery in the long run. Though there is a YES to whether or not it’s good to use a laptop while charging, you’re never too far from turning off everyone around you.

Staying at 100% All the Time is Bad for Battery Health in the Long run

It has already been established that once the battery reaches 100% of its capacity, it will cease to absorb energy and prevent any overheating problems.

It’s not necessary to always be at 100%. These stresses put extra strain on the battery and can potentially ruin it in the long-term; along with causing some trouble for the control system too.

A battery that is constantly being used will wear out faster and have less capacity. Figuratively speaking, this means a fully charged battery will last up to 20% less than an average one for the same period of time.

You can’t escape the feeling of intense heat that emanates from your laptop when it stays plugged in for too long. It’s not just normal, and things really start getting dangerous at an extreme level. But that all depends on how you use your laptop too – because we both know you’re using it nonstop!

#1. Setting A Charging Threshold – The 40 – 80 Spectrum

You can set a charging threshold on your laptop so that when the battery reaches a certain point, it will charge back up to full capacity without stopping.

Laptops have an optimal range of battery power from 40-80%. If the laptop’s battery falls below 40%, the computer will start shutting down, and if it goes over 80%, the laptop will shut off automatically.

In manual terms, it’s essential to plug in the charger when your battery has been drained to around 20%. It is also important to stop charging once it reaches 100%. This approach optimizes your battery life as long as you work on your laptop.

And this is where you’d be getting the most out of your battery.

If you’re looking for an effective way to monitor and balance your laptop battery’s charge cycles, then installing some third-party threshold management software would be a good idea. Most new laptops come with easy-to-access settings that allow you to manipulate these cycles.

#2. You Can Try Taking the Battery Off the Laptop

A work-around for this problem is that you can try taking out the battery (if it’s removable) when it has about 50% or more power left.

You can’t do this unless you’re plugged into an uninterrupted power supply. Your laptop would draw all its power from outside, so it won’t lose battery or shut down for overheating problems.

One way to protect your phone from damage due to overheating is to store it in a cool, shaded area when you’re not using it.

#3. Prevent Your Laptop from Severe Temperatures – Make Sure Proper Ventilation

To keep your laptop from overheating, make sure to use it in an optimally cool environment. In other words, try not to work where there is heavy sun or high temperatures for too long.

And finally, you should check the laptop vents for anything blocking them and make sure that air can pass through freely.

Can I Use My Laptop While Charging It, Even When It’s Fully Charged

The only time when it becomes necessary to unplug the charger from the outlet would be when you know for sure that the battery is full. After all, both your motherboard and lithium batteries monitor how much charge has been received, so they can release or store energy accordingly.

The latest lithium-ion and lithium-polymer batteries cannot charge beyond their capacities – or else they will overheat. As long as you are using your laptop, it does not matter if the battery is being charged or if it has already been fully charged.

Is it bad to charge the laptop while using it?

The use of your laptop, while its battery is charged, is a bad practice you should totally avoid because it can drastically shorten its runtime, causing it to overheat and resulting in thermal throttling.

Is it better to use the laptop plugged in or on battery?

If you use your laptop on batteries, it will last longer and be healthier than if you plug it into a power outlet.

How do I keep my laptop battery healthy?

 A cooling pad is essential for keeping your lithium-ion cell as cold as possible all the time. To maximize the battery’s life, you should also avoid overcharging or using it below 20%.  


As a result of the recent improvements made to lithium ion batteries, newer laptops can now be charged while they are running without any risk of overcharging or damaging them. Is it safe to use a laptop while it is charging? Yes, it is both safe and intelligent.

A modern day computer comes equipped with an intelligence chip that regulates how much power can be supplied at any given time so if too much juice is supplied then the battery will overheat. The Lithium Ion or Lithium Polymer batteries are also made with their own automatic protection system which shuts off when they reach a certain temperature threshold.
