What is Laptop Battery Health and Why Does It Matter?

Laptop battery health is a measure of how well your laptop battery can hold and deliver power. It depends on several factors, such as the type, age, usage, and condition of your battery. A healthy laptop battery can store more energy and provide longer runtimes than a degraded one. A degraded laptop battery can cause various problems, such as:

Reduced battery life and performance
Unexpected shutdowns or restarts
Slow charging or no charging
Swelling or overheating
Damage to your laptop or other components

Therefore, checking your laptop battery health regularly is important to ensure that your device is functioning properly and safely. It can also help you decide when to replace your battery or upgrade your laptop.

How to Check Laptop Battery Health in Windows 10 or 11

If you have a Windows 10 or 11 laptop, you can check your laptop battery health using a built-in feature called the battery report. The battery report is a detailed document that shows various information about your laptop battery, such as:

The name, manufacturer, serial number, chemistry, and design capacity of your battery

The current full charge capacity and cycle count of your battery
The recent usage and charge history of your battery
The estimated battery life based on historical data
The battery capacity history over time
To generate and view the battery report in Windows 10 or 11, follow these steps:
Right-click on the Start icon in your taskbar.

Select Terminal (Admin) (Windows 10 users select "Windows PowerShell (Admin))

Click “Yes” on the pop-up box asking if you want to allow the app to make changes to your system.

Type or copy and paste the following text onto the command line: powercfg /batteryreport /output “C:\battery-report.html”

Press Enter

Open File Explorer > This PC > Windows (C:) and double-click on the “battery-report” file.

Select your web browser of choice to open the file.

You can now see the battery report in your browser window. You can scroll down to see different sections and tables with various data about your laptop battery.

How to Interpret the Battery Report in Windows 10 or 11

The battery report in Windows 10 or 11 can be overwhelming at first glance, but it’s quite easy to understand once you know what to look for. Here are some key terms and indicators that you should pay attention to:

Design Capacity: This is the original amount of energy that your battery was designed to hold when it was new. It is measured in milliwatt-hours (mWh).

Full Charge Capacity: This is the current amount of energy that your battery can hold when it is fully charged. It is also measured in mWh. This value decreases over time as your battery wears out.

Cycle Count: This is the number of times that your battery has gone through a full charge-discharge cycle. A cycle is counted when you use up 100% of your battery’s capacity, regardless of whether it was in one session or multiple sessions. For example, if you use 50% of your battery one day and then recharge it fully, and then use another 50% the next day and recharge it again, that counts as one cycle.

Battery Capacity History: This is a graph that shows how your full charge capacity has changed over time compared to your design capacity. Ideally, you want this graph to be as flat as possible, meaning that your full charge capacity has not decreased significantly over time.

Battery Life Estimates: This is a table that shows the estimated battery life based on historical data. It shows the average, minimum, and maximum battery life that you can expect from your laptop under different scenarios, such as when you are using the battery or when you are charging it. These estimates are not exact, but they can give you a general idea of how long your battery can last.

How to Check Laptop Battery Health in macOS

If you have a MacBook, you can check your laptop battery health using a built-in feature called the battery status menu. The battery status menu is an icon that appears on the menu bar at the top of your screen when your MacBook is running on battery power. It shows the percentage of battery charge remaining and the estimated time until the battery is empty.

To check your laptop battery health in macOS, follow these steps:

Click on the battery status menu icon on the menu bar.
Select Battery Preferences from the drop-down menu.
Click on Battery Health at the bottom of the window.
You will see a pop-up window that shows the maximum capacity and condition of your battery.

You can now see the battery health information in the pop-up window. Here are some key terms and indicators that you should pay attention to:

Maximum Capacity: This is the current amount of energy that your battery can hold when it is fully charged, expressed as a percentage of its original capacity when it was new. For example, if your maximum capacity is 80%, it means that your battery can hold 80% of the energy that it could when it was new.

Condition: This is a status that indicates how well your battery is functioning. There are four possible conditions: Normal, Replace Soon, Replace Now, and Service Battery. Normal means that your battery is healthy and does not need to be replaced. Replace Soon means that your battery is holding less charge than it should and may need to be replaced soon. Replace Now means that your battery is holding significantly less charge than it should and should be replaced as soon as possible. Service Battery means that your battery is not functioning properly and may have a serious problem that requires service.

How to Interpret the Battery Status Menu in macOS

The battery status menu in macOS can also give you some useful information about your laptop battery usage and performance. Here are some tips on how to read and use the battery status menu:

If you see an X icon instead of a percentage or a time estimate, it means that your MacBook cannot communicate with your battery or that your battery is not installed properly. You may need to reset the System Management Controller (SMC) or contact Apple support for help.

If you see a lightning bolt icon next to the percentage or time estimate, it means that your MacBook is plugged into a power source and is charging. The icon will change to a plug icon when your MacBook is fully charged.

If you see an estimate of time remaining until the battery is empty, keep in mind that this estimate is based on your current usage and may change depending on what apps you are running or what settings you are using. For example, if you are watching a video or playing a game, your battery will drain faster than if you are browsing the web or writing a document.

If you want to see more details about your battery usage and performance, you can click on Usage History or Battery History at the bottom of the Battery Preferences window. Usage History shows how much energy your MacBook has used over the past 24 hours or 10 days, broken down by apps and processes. Battery History shows how much charge your MacBook had over the past 24 hours or 10 days, along with the time spent on battery power and AC power.

How to Check Laptop Battery Health in Linux

If you have a Linux laptop, you can check your laptop battery health using various commands and tools available in different distributions and desktop environments. One of the most common and universal commands is acpi, which stands for Advanced Configuration and Power Interface. ACPI is a standard that allows operating systems to control and monitor hardware devices, including batteries.

To check your laptop battery health in Linux using acpi, follow these steps:

Open a terminal window by pressing Ctrl+Alt+T or by searching for Terminal in your applications menu.

Type acpi -i and press Enter.

You will see some output that shows information about your laptop battery, such as its name, model number, serial number, state, charge level, voltage, rate, capacity, and design capacity.

You can now see the laptop battery information in the terminal window. Here are some key terms and indicators that you should pay attention to:

State: This shows whether your laptop battery is charging (Charging), discharging (Discharging), full (Full), or unknown (Unknown).

Charge level: This shows how much charge your laptop battery has left as a percentage of its current capacity.

Capacity: This shows how much energy your laptop battery can hold when it is fully charged as a percentage of its design capacity.
