Is it OK to use a laptop while charging

The battery is less likely to overcharge or overheat, so you don’t have to worry about those things. It is the battery’s mechanism that prevents lithium-ion batteries from overcharging. It is possible to continue charging the battery while it runs out while in use. In the event of a fully charged battery, the laptop can draw power directly from the adapter. You can use the laptop’s battery charge only after removing the wall plug.


Is it OK to use a laptop while charging

You don’t need to worry about whether or not you can use your laptop while it is plugged in and still charging the battery if you are in the middle of a long gaming session or need to get some work done urgently.

You can switch between battery and charging modes whenever possible because that’s what the laptop was designed for. The battery should never be left completely discharged. You may have a defective battery or a damaged adapter if the laptop’s battery does not charge while it is in use.

What happens when we use a laptop while charging?

A laptop can be used while charging without causing any problems. You won’t catch fire or experience an explosion on your laptop if it’s at the right temperature. Your laptop’s lithium-ion battery continues to charge even when it’s not fully charged when you use it. You should use your laptop while charging if you wish to save time.

A lithium-ion battery can be charged while it’s not completely discharged. It needs to be discharged periodically for calibration even though newer laptop batteries can self-calibrate. You must calibrate an older laptop if you own one. A fully discharged battery must be fully charged before it can be calibrated.

With battery calibration, your laptop can calculate the proper battery level because you’re helping it recognize the battery’s true capacity. In the case of an uncalibrated battery, the laptop usually displays the wrong battery level on its screen. The battery level on your laptop might show that it’s fully charged when it’s only 90% charged if you don’t calibrate it.

Is it OK to use a laptop while charging?

A laptop can be used while charging. Based on this assumption, it would help if you had a lithium-ion battery for your laptop to run. In contrast to nickel-based batteries, lithium-ion batteries do not suffer from overcharging.

Overcharging a battery

The NiMH battery is a nickel-based battery with a low tolerance for overcharging, leading to decreased battery life and capacity loss. The temperature of NiMH batteries rises at higher pressures, resulting in the loss of electrolytes. Therefore, it is advisable not to use your laptop while charging if it has a NiMH battery.

In contrast, lithium-ion batteries do not overcharge. To prevent overcharging, it is designed with a control system. If the battery reaches full capacity, the system instructs it to stop charging. The lithium-ion battery on your laptop makes it easier to use while charging. There are almost 500 charges you can make with a lithium-type battery.

The lithium-ion battery should be kept at its peak cut-off for a shorter time to avoid compromising its safety. The battery will be less likely to suffer damage if it is cut off. A battery’s voltage drops when it is not charged. In this case, the battery will settle between 3.70 V/cell and 3.90 V/cell which is safer.

A fully charged battery has long-lasting voltage elevation. On the other hand, a less saturation charge will have a shorter voltage elevation period. When using your laptop, consider how long it will be in use. Is the product expected to last a short time or a long time? The environment’s temperature must also be taken into account. The weather is either cold or hot.

The laptop can be used while charging while you’re using it for a short time, let’s say for an hour in a hot environment. You can also use it in a cold environment for a long time. In a hot environment, it may cause problems after eight hours.

Overheating of battery

The performance of lithium-ion batteries is affected by overheating. In a study, lithium-ion battery performance drops almost double at 45°C or 113°F. Batteries’ lifespan is directly proportional to the cycle of the battery which is affected by high temperatures.

Studies have shown that batteries lose 3.3% of their capacity after 200 cycles at 25C or 77F. The degradation level doubles when the temperature reaches 45C or 113F. A test result showed a degradation level of 6.7%. A higher temperature reduces the battery’s lifespan faster. The battery’s lifespan decreases if it’s repeatedly exposed to high temperatures.

If you’re planning to use your laptop for a long period, it’s better to remove the battery if your device can be removed. You should work in a cold environment if it does not have a removable battery. In addition to the USB fan, you can use a fan to maintain the proper temperature inside the laptop.

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

The battery on your laptop should be removed and plugged into an electrical outlet if it has a removable battery. The best time to do this is if you’ll be using your laptop as a desktop computer or working from home. It is usually the case that keeping your laptop on for a long time causes the battery temperature to rise which adversely affects the battery’s performance. The battery should have a 50% charge before being stored. In addition, it will help preserve the battery to last for a long time.

Your laptop’s battery should be removed before it reaches 100% if you have a removable battery. A charge of 80% or less is safer. According to a Battery University study, the last 3% of a battery’s life consumes a vast amount of energy. It decreases the battery’s lifespan when it has to be fully charged.

You should avoid charging your laptop’s battery to 100% if the battery is not removable. The battery won’t receive high voltage when it has a low battery level, so there is no chance of saturation charging. It is beneficial for the battery to have a low saturation charge because it will help it last longer.

Voltage and discharge cycle

In a fully charged battery, there is 4.2 V per cell. A laptop user will most likely charge the battery fully when an electrical socket is unavailable. The voltage is not ideal since it reduces the discharge cycle which reduces battery life.

In contrast, a battery with an 85% to 95% battery level has a 4.10 V/cell voltage. According to the study, there had been an improvement in the discharge cycle. It was found that low voltage batteries have a high discharge cycle. A battery’s life is prolonged by high-discharge cycles.

It was shown that voltage decreases result in significant improvements when comparing several battery levels. The battery level is between 85% and 90% at one point. In addition to 300 to 1000 extra charges, it also improves the discharge cycle. A battery with a 65% to 75% level has a quadrupled discharge cycle.

Does Using Laptop While Charging Affect Battery Life?

Battery technology can handle this practice but excessive overheating can be problematic. It shouldn’t be a big deal until temperatures begin to rise. If the battery is exposed to high temperatures for an extended time, it will deteriorate.

There will not be a sudden death of the battery but the capacity slowly diminishes over time. No need to worry about not having too much heat as the laptop will survive.


It is important to remember three things when using a lithium-ion battery laptop. The battery level, temperature and voltage are all included. It is important to keep your laptop well-ventilated or in a cool place as much as possible. To maintain a low voltage, you must ensure a low battery level. These three tips will prevent your laptop from having any problems.
