However, as long as you take some basic precautions, such as using a surge protector and keeping the cords out of the way, the benefits of keeping your MacBook plugged in far outweigh the risks.

Battery health

When a MacBook battery is discharged completely, it can damage the battery and shorten its lifespan. This is because the battery’s cells are stressed when they are completely discharged, and this stress can lead to the formation of dendrites. Dendrites are small, needle-like crystals that can grow on the battery’s electrodes and cause the battery to short circuit.

Keeping your MacBook plugged in helps to prevent the battery from discharging completely, and this can help to extend the battery’s lifespan. When the MacBook is plugged in, the power supply provides electricity to the computer, which means that the battery is not being used to power the computer. This allows the battery to rest and recharge, which can help to prevent the formation of dendrites and extend the battery’s lifespan.

In addition to extending the battery’s lifespan, keeping your MacBook plugged in can also help to improve the computer’s performance. When the MacBook is running on battery power, the computer may throttle its performance in order to conserve battery life. However, when the MacBook is plugged in, the computer can run at full power without having to worry about draining the battery.

Overall, keeping your MacBook plugged in is a good way to extend the battery’s lifespan and improve the computer’s performance.

Battery life

Every time you charge and discharge your MacBook’s battery, it goes through a charge cycle. The number of charge cycles a battery can go through is limited, and once the battery reaches its cycle limit, it will no longer be able to hold a charge.

Plugging in your MacBook helps to reduce the number of charge cycles it goes through by allowing the battery to rest and recharge. When the MacBook is plugged in, the power supply provides electricity to the computer, which means that the battery is not being used to power the computer. This allows the battery to rest and recharge, which can help to extend its lifespan.

Overall, keeping your MacBook plugged in is a good way to extend the battery’s lifespan and improve the computer’s performance.

Performance

This is an important consideration because when your MacBook is running on battery power, it may throttle its performance in order to conserve battery life. This can lead to slower performance and a less enjoyable user experience.

For example, if you are using your MacBook to edit videos or play games, you may notice that the performance is not as good when running on battery power. This is because the computer is throttling its performance in order to conserve battery life.

However, when your MacBook is plugged in, it can run at full power without having to worry about draining the battery. This means that you can get the best possible performance from your computer, regardless of what you are using it for.

In addition, keeping your MacBook plugged in can also help to extend the battery’s lifespan. This is because the battery is not being used to power the computer when it is plugged in, which can help to reduce the number of charge cycles it goes through.

Overall, keeping your MacBook plugged in is a good way to improve its performance and extend the battery’s lifespan.

Convenience

The convenience of keeping your MacBook plugged in cannot be overstated. Modern life is full of distractions and demands on our attention. Juggling work, personal commitments, and social obligations can be overwhelming at times. Relying on our devices to perform as expected is crucial for maintaining productivity and peace of mind. Imagine the frustration of being engrossed in a critical project, only to have your MacBook unexpectedly shut down due to a depleted battery. This can not only disrupt your workflow but also lead to lost data and missed deadlines.

The simple act of keeping your MacBook plugged in eliminates this concern entirely. You can focus on the task at hand without the nagging worry of your battery running low. This not only enhances convenience but also provides peace of mind, allowing you to fully engage in your activities without distractions.

In addition to the convenience it offers, keeping your MacBook plugged in can also contribute to extending the battery’s lifespan. When a MacBook is running on battery power, the battery is constantly discharging and recharging, which can gradually reduce its capacity over time. By keeping your MacBook plugged in, you can reduce the number of discharge cycles the battery goes through, thereby extending its overall lifespan.

In summary, keeping your MacBook plugged in is not only convenient but also beneficial for the longevity of the battery. By eliminating the worry of running out of battery power and reducing the number of discharge cycles the battery goes through, you can ensure that your MacBook is always ready to perform when you need it most.
