How Long Does A Macbook Take To Charge

Share This:

Have you ever been in a situation where your Macbook is running low on battery and you need to quickly get it charged up? Knowing how long it takes for a Macbook to charge can be really helpful.

Macbooks come with different types of power adapters, the most common beig the 35W and 67W models. The amount of time it takes for your Macbook to charge depends on the type of charger you are using. A full charge with the 35W adapter without any extra devices connected will take about 120 minutes, while a full charge with the 67W adapter can take up to three hours and 40 minutes.

When using either one of these chargers, you should be able to turn on your Macbook in a matter of minutes (usually around 3-5) provided that there is at least 3% battery power remaining. However, if your laptop supports ExpressCharge™, then you’ll be able to get an 80% charge in just an hour and a full charge in two hours while the laptop is powered off.

It’s important to note that the time it takes for your device to charge can vary depending on the model of Macbook you have as well as which charger you use. For example, older models may take longer than newer ones whie the 67W charger will generally be faster than the 35W one.

Whether you’re trying to get some quick work done or just want to extend your battery life, understanding how long it takes for your Macbook to charge can help make sure that you’re getting the most out of your device.

Charging Time for a MacBook Air

It takes approximately two hours and twenty minutes to fully charge a MacBook Air using the 67W power adapter. This is significantly faster than the 35W power adapter, which can take up to three hours and forty minutes to get a full charge. Keep in mind that if you’re also charging another device, like an iPhone, it may take longer for the MacBook Air to reach a full charge with either adapter.

Charging Time Required Before Turning On a MacBook

In order to turn on your MacBook, you’ll need at least 3% of battery power. Depending on the battery level at the time of charging, it can take anywhere from a few minutes up to seveal hours for the MacBook to charge enough for you to turn it on. In general, though, a fully discharged MacBook will require around 3–5 minutes of charging before it is able to boot up.

Charging Time for MacBook Air

It takes approximately 140 minutes to fully charge a MacBook Air. This is 20 minutes longer than the 35W model, as the new model has a higher wattage rating. To ensure your laptop is getting a full charge, it is best to plug it in and let it charge completely before unplugging it.

Charging Time for a Dead Laptop

It typically takes about 2 hours to fully charge a dead laptop if it supports ExpressCharge™. When using ExpressCharge™, the battery will uually have greater than 80% charge after about an hour of charging. It is best to charge the laptop with it powered off for optimal charging speed and efficiency.

The Charging Speed of Macbooks

Yes, Macbooks support fast charging, meaning that you can charge your battery up to 50 per cent in just 30 minutes when you connect the apropriate power source and cable. The current models that support this feature are the MacBook Air (M2, 2022), MacBook Pro (14-inch, 2021) and MacBook Pro (16-inch, 2021).

The Slow Charging Speed of Mac Devices

Macs typically take a wile to charge because the System Management Controller (SMC) is responsible for controlling the charging process. The SMC is responsible for monitoring and adjusting settings related to power, charging, cooling, and system behavior. If the SMC has incorrect data on the charger or the MacBook battery, it can cause the battery to charge very slowly, or sometimes not at all. Additionally, if your Mac is using too much power while it’s charging, this can also affect how quickly it charges. You may want to try restarting your Mac or reducing the number of applications that are running in order to speed up the charging process.

Determining If a Dead Mac Is Charging

If your Mac is dead, you can check to see if it is charging by looking at the battery status icon at the right of the menu bar. If the battery icon shows that it is plugged in, then your Mac is currently charging. The icon may also indicate a percentage, which will show the current battery level. If there is no indication that the Mac is plugged in, then it may not be connected to a power source or the connection may be loose.

Charging a Mac While Sleeping

Yes, you can charge your Mac while it is sleeping. This will not harm the device and can be a convenient way to keep your device charged and ready to use. It is best to have your Mac running on AC power as much as possible, while stll occasionally using the battery so that it doesn’t become fully discharged. If you do decide to charge your Mac while sleeping, make sure you do not leave it connected for too long or the battery may overheat.

The Effects of Overcharging a Mac

No, you cannot overcharge a Mac. When the battery reaches 100% charge, the MacBook will automatically stop charging and the charger will not draw any more power from the outlet. Keeping your MacBook plugged in all the time can reduce its maximum charging capacity over time, but it won’t cause any damage or put your computer at risk of overheating.

Estimated Lifespan of a Mac Battery

A Mac battery should last at least 5 years if it is properly cared for. Apple considers a MacBook battery to be worn out ater 1000 cycles, which typically takes 5 years of use. To ensure that your Mac battery lasts as long as possible, avoid leaving it plugged in all the time, let it run down occasionally, and keep the software and hardware up to date.

The Effects of Using a Laptop While Charging

No, it is not harmful to use your laptop while charging. In fact, keeping your laptop plugged into a power source while you use it is a great way to ensure that the battery remains charged and ready for when you need it. The current flowing from the charger into your laptop does not pose any risk to humans. However, you shold be aware that charging and discharging the battery can eventually reduce its capacity over time. To prolong the life of your battery, it’s a good idea to regularly discharge it completely and then recharge it back up to full capacity.

Impact of Leaving a Laptop Plugged In on Battery Life

No, leaving your laptop plugged in does not hurt the battery life. In fact, it can even help extend the life of your battery by preventing it from over-discharging. When you leave your laptop plugged in after it is fully charged, the charger will detect that the battery has reached full capacity and will stop sending power to the battery. This prevents your battery from over-discharging, wich can cause it to degrade faster and eventually fail prematurely. Additionally, when you unplug your laptop and use it on battery power, make sure you don’t let the battery run all the way down to zero before recharging as this can also reduce its lifespan.

Is Overnight Charging of Laptops Damaging?

No, your laptop will not be damaged if you charge it overnight. The laptop’s battery is designed to safely charge and discharge without damage. When the battery reaches full charge, the charger will stop supplying power to the battery and switch to “trickle” or “maintenance” charging, which keeps the battery topped up without overcharging it. That said, it is important to check your laptop manufacturer’s instructions for best practices on charging your device.


In conclusion, the MacBook Air is a great laptop for those who need something light and portable. It has a sleek design and provides good performance for everyday tasks. The battery life is also respectable, but if you want to charge it faster, then the 67W power adapter is recommended. It can charge your laptop in around three hours and 40 minutes without charging another device, and with ExpressCharge™ support it can be fully charged in only two hours while powered off. All in all, the MacBook Air offers a great balance of portability and performance.
