How Long to Charge a Laptop? Simple Guide

It is possible to power a laptop with either an AC or a DC adapter. These (power) chargers, also known as adapters, help transform the current coming from the wall outlet into a form the laptop can use.

As soon as you’re running low on battery, you’ll want to know How Long to Charge a Laptop?. Laptops take longer to charge if there are several variables at play. Battery cells, whether or not it was wholly depleted before plugging in for a charge, and whether or not to switch it on are all factors that could come into play. If turned off, your laptop will take 1.5 to 2.5 hours to recharge.

Should You Shut Down Your Laptop Every Night?

If you want to shut down your laptop entirely, you should press the Windows key and select the power option, followed by the shutdown. Other means of shutting down the laptop, such as disconnecting the power cord or pressing the power button for an extended time, can damage its components.

Your laptop’s usage rate determines when you should shut it down. It’s recommended to leave your laptop on overnight if you use it regularly during the day but shut it down if you use it occasionally. The surge of current necessary to start up an older laptop is a common cause of damage.

The laptop’s components degrade faster when turned on and off frequently, resulting in a shorter lifespan. To put it another way, overheating is a computer’s worst enemy; thus, leaving the laptop on is terrible.

How Long to Charge a Laptop

The time required to charge your laptop battery is generally determined by:

  • Your laptop’s battery type
  • Your laptop’s charger type
  • Whether you’re using your laptop or not while it charges
  • Whether or not your laptop incorporates Fast Charge technology

Sure batteries have a higher voltage capacity than others, and batteries with a higher voltage typically take longer to recharge. That’s not always a bad thing; a higher-voltage battery will also keep your laptop powered for a more extended period.

As mentioned earlier, the time required to charge a laptop depends on several factors, including the number of cells to be charged and whether the laptop is turned on or off. Continue reading to learn more.

The number of battery cells affects the time required to charge fully. Six-cell batteries charge more quickly than nine-cell batteries. The type of adaptor used also affects the charging duration. Certain adapters are designed for heavy-duty use and charge more quickly.

Battery health is another factor to consider when determining how long a laptop’s battery takes to charge. Additionally, the charging time can be reduced or increased if there is a problem with the laptop drivers or the charging circuit.

Finally, whether the laptop is turned on or off affects the charging time. Keeping this in mind, the duration of the charging process varies. Charging takes approximately 1.5 to 2 hours when the laptop is turned off and completely depleted.

It is recommended that you charge a new laptop or laptop battery for 24 hours and then avoid using it until it is completely depleted of power. Avoid overcharging, as modern computers will automatically stop charging once the battery reaches capacity and switch to AC power.

Charging a new laptop in this manner extends the battery’s life. Always remember to keep the laptop cool to avoid damaging the battery. If you are not going to use the battery for an extended period, it is recommended that you charge it to approximately 50% before storing it. For laptops with removable batteries, it is recommended that you remove the battery and store it separately from the computer.

Additionally, when charging and the laptop begins to heat up, you should unplug it and allow it to cool for a few minutes or remove the removable battery and allow it to cool for a few minutes, thereby avoiding battery cell damage. When a laptop is turned off, it charges faster than when it is still in use.

What Are the Best Laptop Battery Charging Techniques?

Not all laptops include detachable batteries for cooling. Additionally, internal cooling fans may fail after a few years. Here are some excellent laptop battery charging suggestions from FossBytes that should help you get the most out of your laptop’s battery life:

  • Avoid completely discharging your laptop after charging it. The best course of steps is to keep the battery amount between 40% also 80%.
  • Ascertain that your laptop does not rehaeted and that the cooling fan is operating exactly.
  • Your laptop battery cannot “overcharge” and cause damage to itself. It is sufficiently intelligence to avoid charging energy.
  • Batteries that are fully charged have a maximum discharge cycle of 300-500. Those charged to approximately 80% receive nearly quadruple the number of recharge cycles.

PC Mag also includes some critical laptop battery charging tips, such as performing battery backup, disabling unused devices and ports, and selecting battery saver or eco mode, which puts your laptop into lower power states and thus drains the battery-less.

How Do You Determine When Your Laptop Is Completely Charged?

There are two methods for determining whether or not your laptop is ultimately charged. When the computer is still on, the first method is used. Move the cursor to the bottom right corner of your display, where you will see a battery icon.

By left-clicking on the battery icon, the power percentage is displayed. If it is not fully charged, it is not at 100%. When the laptop is switched off, the other method is used. A light is usually visible adjacent to the power port. When some older laptops are charging, the light glows an amber colour; it changes to white once fully charged.

However, new laptops display a white light while charging and then turn off when fully charged with the second method. However, there is no loss in leaving the battery plugged in even if it is fully charged. Due to the fact that excessive heat might make the battery to appear completely charged when it is not, unplug it and allow it to cool for a bit.

FAQs – How Long to Charge a Laptop?

How Do I Determine the Health of My Laptop Battery?

Navigate to Settings > Battery > Battery Usage to check the battery status of your Android phone. However, if you’re looking for detailed battery health analytics on your phone, we recommend the AccuBattery app. AccuBattery becomes more adept at analysing the performance of your battery the more you use it.

Are 5 Hours of Battery Life Good for a Laptop?

This figure varies according to the brand and capacity of the laptop’s battery and how the laptop is used. Additionally, it is necessary to keep in mind that performance can degrade over time. While some laptops’ batteries can last for tens of hours, others (particularly gaming laptops) have a maximum battery life of 4-5 hours.

When Should I Replace My Laptop Battery?

Laptop batteries typically fail after 1-2 years or 300-400 charge cycles. If your laptop is older, the battery is almost certainly at the end of its useful life and has to be changed.

Why Is My Laptop Shutting Off When I Unplug It?

If your laptop immediately shuts down after being unplugged from a power source, this indicates that your battery is dead. Another possibility is that your laptop’s battery connector is faulty. It may occur for the same reason that the battery may become damaged.

Is Using a Laptop Without a Battery Possible?

Without a battery, it is possible to use a laptop. However, you must plug it into a power outlet for your laptop to operate. It will immediately shut down if you unplug it, just like a regular computer. Otherwise, using your laptop without a battery is entirely acceptable.


Would you like to know How Long to Charge a Laptop? With today’s lithium battery cells, plugging the laptop in for extended periods will not significantly reduce the battery life. What should be avoided is exposing the battery to excessive heat and operating it until it is completely depleted, as this will destroy the battery.

Once your laptop is fully charged, it switches to AC power; this prevents the battery from being overcharged, and, unlike smartphones, a laptop does not use the cell’s current when plugged into power. Rather than that, it makes use of the ac, which is especially advantageous when the battery is fully charged.
