How to Check Mac Battery Health?

Share This:

The battery life of a MacBook is a crucial factor to consider when purchasing a new laptop. After all, you want your device to last as long as possible without needing to be constantly plugged in. In this article, we will delve into the world of Mac batteries and provide you with insights on how to check your Mac battery health.

Let’s start by discussing the average lifespan of a MacBook battery. The duration of a single charge can vary depending on the model you own. For instance, the MacBook Air 2020 typically lasts between 8 to 14 hours, while the MacBook Pro 16-Inch 2019 can run for approximately 3 to 9 hours. These estimates may fluctuate based on your usage patterns and settings.

Now, let’s move on to the important aspect of checking your Mac battery health. It is essential to monitor the health of your battery to ensure that it is functioning optimally. A healthy battery will provide you with longer-lasting power, while a deteriorating one may result in decreased performance.

To check your Mac battery health, follow these steps:

1. Open the Search bar on your taskbar and type “Command prompt.”
2. Press and hold (or right-click) on Command prompt, and select “Run as administrator.”
3. Click “Yes” to grant administrative access.
4. In the command prompt, type “powercfg /batteryreport” and hit Enter.
5. Wait for the process to complete.

Once the process is finished, a battery report will be generated in the form of an HTML file. This file is stored in a specific folder on your PC. Open the file to access the battery report.

Within the battery report, you will find information about your battery’s health, capacity, and usage patterns. The most crucial aspect to look for is the battery’s capacity, which indicates its maximum charge holding capability. If your battery health is at 100%, congratulations, your Mac battery is in excellent condition. However, if it falls around 90%, your battery is in the middle of its lifespan. Anything below 80% indicates that it is time to consider replacing your battery with a new one.

Regularly checking your Mac battery health is essential to keep your device functioning optimally. It allows you to plan your usage accordingly, especially when you are on the go and may not have access to a power source. By monitoring your battery health, you can ensure that your Mac remains efficient and reliable.

Understanding your Mac battery life and checking its health are crucial for maintaining optimal performance. By following the steps mentioned above, you can easily assess your battery’s health and make informed decisions regarding its usage. Remember, a healthy battery leads to a happy and long-lasting Mac experience.

What is A Bad Battery Health For Mac?

A bad battery health for a Mac refers to a situation where the battery’s capacity has significantly degraded over time, affecting its ability to hold a charge and provide power to the device. When a Mac’s battery health drops below 80%, it is considered to be in a poor state and may need to be replaced.

Here are some key points to understand about bad battery health for a Mac:

1. Maximum Capacity: The maximum capacity of a battery indicates how much charge it can hold compared to when it was new. A brand new battery would have a maximum capacity of 100%. As the battery ages and goes through charging cycles, its maximum capacity gradually decreases.

2. Lifespan: When the battery health is around 90%, it means that the battery is still in the middle of its lifespan. At this point, the battery may show some signs of degradation, but it can still provide a reasonable amount of battery life.

3. Replacement Recommendation: Once the battery health drops below 80%, it is generally recommended to replace it with a new one. A battery with a health below this threshold may exhibit significant degradation, resulting in reduced battery life and performance.

4. Symptoms of Bad Battery Health: Some common signs of a bad battery health include shorter battery life, the need to charge the device more frequently, unexpected shutdowns even when the battery percentage is not low, and a battery that drains quickly.

It is important to note that battery health can vary depending on factors such as usage patterns, charging habits, and the age of the Mac. Regularly monitoring the battery health and taking appropriate steps, such as optimizing battery settings and charging habits, can help prolong the lifespan of the battery.

What is Normal Mac Battery Life?

The normal battery life of a Mac can vary depending on the model. Here is a breakdown of the average battery life you can expect from different MacBook models:

1. MacBook Air 2020: On a single charge, the battery can last anywhere between 8 to 14 hours.

2. MacBook Pro 13-Inch 2020: The battery life for this model ranges from 6 to 11 hours on a single charge.

3. MacBook Pro 16-Inch 2019: The battery life of the 16-inch MacBook Pro can last between 3 to 9 hours per charge.

4. MacBook Pro 13-Inch 2019: Similar to the 16-inch model, the battery life of the 13-inch MacBook Pro is also in the range of 3 to 9 hours.

It’s important to note that these are average estimates and the actual battery life may vary depending on various factors. Factors that can affect battery life include screen brightness, running resource-intensive applications or software, Wi-Fi usage, and overall system settings.

To optimize your Mac’s battery life, you can take the following steps:

– Adjust screen brightness: Lowering the screen brightness can significantly extend battery life.
– Manage background processes: Close unnecessary applications and processes running in the background.
– Use energy-saving settings: Adjust your Mac’s system settings to conserve power, such as enabling the power-saving mode or reducing the time for the screen to turn off when inactive.
– Disconnect unnecessary peripherals: Unplug any devices or peripherals that are not in use, as they can drain battery life.
– Update macOS and applications: Keeping your operating system and applications up to date can help optimize battery performance.

By following these tips and considering the average battery life for your specific MacBook model, you can maximize the usage time you get from a single charge.


The battery life of a MacBook can vary depending on the model and usage. The latest MacBook Air 2020 model can last anywhere between 8 to 14 hours on a single charge, making it an ideal choice for long-lasting battery performance. The MacBook Pro 13-inch 2020 model offers a slightly lower battery life of 4 to 10 hours, while the MacBook Pro 16-inch 2019 model can last between 6 to 11 hours. The older MacBook Pro 13-inch 2019 model also provides a battery life of 3 to 9 hours.

It is important to note that these battery life estimates are based on average usage and can be influenced by various factors such as screen brightness, running multiple applications, and internet connectivity. Additionally, battery health plays a significant role in determining the overall battery life of a MacBook.

To maintain optimal battery health, it is recommended to keep the battery charged between 20% to 80% and avoid extreme temperatures. Regularly updating the macOS and managing power-hungry applications can also help extend the battery life.

Monitoring the battery health is crucial, and it is advised to check the battery’s maximum capacity periodically. If the battery health drops below 80%, it is recommended to consider replacing it with a new one to ensure uninterrupted usage.

MacBooks offer decent battery life that can cater to different needs and usage patterns. However, it is essential to manage and maintain the battery properly to maximize its lifespan and performance.
