How to Check and Improve Your Laptop Battery Capacity in 2023 (Windows 11 Guide)

How to Check Laptop Battery Capacity in 2023

If you use a laptop, you probably know how important it is to keep an eye on your battery capacity. Battery capacity is the amount of charge that your battery can hold and deliver to your laptop. It affects how long your laptop can run on battery power, and how often you need to plug it in.

But how do you check your battery capacity in 2023? And what can you do to improve it or replace it if it’s low? In this blog post, we will answer these questions and more. We will show you how to generate a battery report using Windows 11, how to interpret the results, and how to optimize your battery life. We will also share some tips and tricks to preserve your battery health and performance.

How to Generate a Battery Report in Windows 11

One of the easiest ways to check your battery capacity in 2023 is to use the built-in tool in Windows 11. This tool allows you to create a detailed report about your battery health, usage, and history. To generate a battery report in Windows 11, follow these steps:

Right-click on the Start icon and select Windows Terminal (Admin). Click Yes when prompted for permission.

In the Windows Terminal window, type the following command and press Enter: powercfg /batteryreport /output "C:\battery-report.html"

This command will create a battery report file named battery-report.html and save it to the C drive. You can change the file name and location if you want.

Open File Explorer and navigate to the C drive. Double-click on the battery-report.html file to open it in your default web browser.

How to Read a Battery Report

The battery report will show you various information about your battery, such as:

Basic information: This section shows you the name of your computer, product name, BIOS version and date, OS build, platform role, and power state.

Installed batteries: This section shows you the number of batteries installed on your laptop, their manufacturer name, serial number, chemistry type, design capacity, and full charge capacity.

Recent usage: This section shows you the power states (active, suspended, hibernate) of your laptop over the last three days, along with the start time, end time, source (AC or battery), and remaining capacity for each state.

Battery usage: This section shows you a graph of the battery drains over the last three days.

Usage history: This section shows you the history of system usage on AC and battery power over the last three weeks.

Battery capacity history: This section shows you the history of the full charge capacity and design capacity of your battery over the last three weeks.

Battery life estimates: This section shows you the estimated battery life based on observed drains over the last three weeks.

How to Interpret the Results

The most important sections of the battery report are the installed batteries, battery capacity history, and battery life estimates. These sections will help you determine the current condition and performance of your battery.

The installed batteries section will show you the design capacity and full charge capacity of your battery. The design capacity is the amount of charge that your battery was designed to hold when it was new. The full charge capacity is the amount of charge that your battery can hold now after being used for some time.

The difference between these two values indicates how much your battery has degraded over time. A healthy battery should have a full charge capacity close to its design capacity. A degraded battery will have a lower full charge capacity than its design capacity.

The battery capacity history section will show you how the full charge capacity and design capacity of your battery have changed over time. You can see if your battery has been losing its charge gradually or rapidly. A gradual decline is normal for lithium-ion batteries, which lose their capacity due to aging and usage. A rapid decline may indicate a problem with your battery or charging system.

The battery life estimates section will show you how long your laptop can run on battery power based on observed drains over time. You can see if your laptop’s battery life has been consistent or fluctuating. A consistent battery life means that your laptop is using power efficiently and optimally. Fluctuating battery life may mean that your laptop is running too many background processes or has faulty hardware or software.

How to Optimize Your Battery Life

If you find that your laptop’s battery capacity is low or declining fast, or that your laptop’s battery life is short or inconsistent, there are some steps you can take to optimize your battery life. Here are some tips and tricks to improve your laptop’s battery performance:

Adjust your power settings: You can choose from different power plans in Windows 11 that affect how your laptop uses power. You can access them by clicking on the battery icon in the taskbar and moving the slider between Best Performance and Best Battery Life. You can also customize your power plan by going to Settings > System > Power & sleep > Additional power settings. You can tweak settings such as screen brightness, sleep time, hibernate time, and processor power management.

Use battery saver mode: You can enable battery saver mode in Windows 11 by clicking on the battery icon in the taskbar and turning on the switch. Battery saver mode will reduce your screen brightness, limit background activity, and extend your battery life. You can also set battery saver mode to turn on automatically when your battery level falls below a certain percentage by going to Settings > System > Battery > Battery saver settings.

Update your drivers and software: You can update your drivers and software in Windows 11 by going to Settings > Update & security > Windows Update. Updating your drivers and software can fix bugs, improve performance, and enhance compatibility. You can also use HP Support Assistant or other manufacturer-specific tools to check for updates for your laptop model.

Uninstall or disable unnecessary programs: You can uninstall or disable unnecessary programs in Windows 11 by going to Settings > Apps > Apps & features. Uninstalling or disabling unnecessary programs can free up disk space, memory, and CPU resources, and reduce power consumption. You can also use Task Manager to see which programs are using the most power and end them if needed.

Avoid extreme temperatures: You can avoid extreme temperatures by keeping your laptop away from direct sunlight, heat sources, or cold environments. Extreme temperatures can damage your battery and affect its performance. You should also avoid using your laptop on soft surfaces such as pillows or blankets that can block ventilation and cause overheating.

Calibrate your battery: You can calibrate your battery by fully charging it, then letting it drain completely until it shuts down, and then charging it again to 100%. This will reset the battery gauge and help it display the accurate charge level in Windows 11. You should calibrate your battery once every few months or when you notice a significant discrepancy between the reported and actual charge levels.

How to Replace Your Battery

If you find that your laptop’s battery capacity is very low or has failed, or that your laptop’s battery life is very short or unreliable, you may need to replace your battery. Replacing your battery can restore your laptop’s performance and extend its lifespan.

To replace your battery, you will need to buy a new battery that is compatible with your laptop model. You can check the model number of your battery by removing it from your laptop and looking at the label. You can also use HP PartSurfer or other manufacturer-specific tools to find the right battery for your laptop.

To replace your battery, you will need to follow the instructions in your laptop’s user manual or online support page. You may need some tools such as a screwdriver or a pry tool to open the laptop case and remove the old battery. You should also follow some safety precautions such as turning off your laptop, unplugging the power cord, and wearing an anti-static wrist strap.

Once you have replaced your battery, you should charge it fully before using it. You should also calibrate your battery as described above to ensure that it displays the correct charge level in Windows 11.

Conclusion

Checking your laptop’s battery capacity in 2023 is easy with Windows 11’s built-in tool. By generating a battery report, you can see how healthy and efficient your battery is, and how long it can last on a single charge. You can also optimize your battery life by adjusting your power settings, using battery-saver mode, updating your drivers and software, uninstalling or disabling unnecessary programs, avoiding extreme temperatures, and calibrating your battery.
