In such cases, you need to replace your MacBook charger immediately. Using a charger with any of these symptoms poses a significant risk to your MacBook. If you purchased your device from an authentic Apple outlet, your MacBook charger would be replaced at no cost.

Note that your device must be covered under AppleCare for it to be replaced. If you don’t meet these requirements, you will have to pay for a new MacBook charger. However, you might get a new charger at a discounted price if you make a strong case. Either way, you must replace a faulty or burnt MacBook charger for the sake of your device. Using damaged chargers can affect the stability of your battery and damage your MacBook altogether.

Can You Keep a MacBook Charger Plugged in?

MacBooks can be so addictive due to their fascinating features. As a result, you may be tempted to use them all the time, a habit that drains their battery faster. This may tempt you to keep your MacBook charger plugged in.

It is not a good idea to keep your MacBook charger plugged in. This can affect the battery life and damage your MacBook’s charging system. Therefore, it will be better if you unplug your MacBook charger after the battery is fully charged. Only plug it in when the battery needs charging. This will help regulate the battery levels and maintain its durability. Knowing how to handle your MacBook battery will go a long way in safeguarding it.

Generally, laptops are as good as their batteries. Taking good care of your MacBook battery is crucial for its durability and ensuring it can retain a charge. Constantly leaving your MacBook charger plugged in could affect your battery and trigger other factors like excessive heat. Such factors can worsen your battery life. Keep in mind there are different types of batteries.

In most cases, MacBooks use lithium-ion batteries. These batteries don’t suffer from the harmful “memory effect,” unlike their nickel-based counterparts. This means that when you discharge and recharge lithium-ion batteries, you won’t cause significant damage to their durability. Once a laptop battery is fully charged, it automatically stops charging. Therefore, the risk of a damaged battery is significantly low.

Note that your MacBook battery can only avoid damage when you leave them plugged in and not using them. However, when you use them while they are charging, the chances of battery damage are high. Therefore, you should only leave the MacBook charger plugged in when not using the device to avoid damage.

If your MacBook uses lithium-ion batteries, you should avoid discharging them completely then recharging them fully. This process is commonly referred to as “deep cycle,” and only works on nickel-cadmium batteries. In simpler terms, a deep cycle is using your laptop until the battery is 0%, then recharging it to 100%.

This habit can be harmful to lithium-ion batteries. However, you are advised to perform a deep cycle once every two months to help recalibrate the battery. This is important because it allows the battery mechanics to remain accurate when showing the battery charge. Avoid deep cycling regularly because it will damage your MacBook’s battery life.

Apart from damaging the battery life, leaving your MacBook charger plugged in results in excessive heat that is dangerous for your device. Processor-intensive apps like games trigger excessive heat levels. Your MacBook could also get overheated when you have many programs running simultaneously.

Leaving your MacBook charger in such cases can damage your device significantly. Therefore, you should unplug the charger, switch off the device, and let it cool down. This will go a long way in preventing heat damage.

If you want to perform a deep cycle, start by charging your MacBook battery to full capacity. Then, let it cool down for around two hours to get rid of the heat. It would help if you then unplugged the charger and set the device’s power save settings to 5%. The cycle will start once the battery level drops down to five percent. As mentioned earlier, deep cycling should only be done once in two months.
