Press the Windows key and type ‘cmd’ to open the Command Prompt.

Right-click on Command Prompt and select ‘Run as administrator’.

Look for a file named "battery-report.html."

Double-click on the file to open it in your web browser.

  • Review the battery report
The battery report provides detailed information about your laptop’s battery health:

Battery usage: This section shows the battery usage over time, including recent usage and usage history.

Battery capacity: This section compares the design capacity (the original capacity of the battery) with the current full charge capacity. A significant difference between these values indicates battery wear.

Battery life estimates: This section provides estimates of battery life based on recent usage patterns.

  • Use third-party software
If you prefer a more user-friendly interface, you can use third-party software to check your battery health:

Download and install a battery health monitoring app like BatteryInfoView or HWMonitor.

Open the app and follow the instructions to view detailed information about your battery’s health, including capacity, wear level, and charge cycles.

How to improve laptop’s battery life?
By following these steps, you can effectively improve your laptop’s battery life, ensuring it lasts longer and performs better throughout the day.

  • Adjust screen brightness: Reducing your screen brightness can significantly extend your laptop’s battery life. Go to your laptop’s settings and lower the brightness to a comfortable level. You can also use the keyboard shortcuts to adjust brightness quickly.
  • Use power-saving mode: Most laptops have a power-saving mode that optimises settings to extend battery life. On Windows, go to Settings, select System, then Power and Sleep, and choose a power-saving plan. On macOS, go to System Preferences, select Battery, and enable the power-saving mode.

  • Unplug peripherals: External devices like USB drives, external hard drives, and other peripherals can drain your battery. Unplug any devices you are not using to conserve battery power.
  • Keep your laptop cool: Overheating can reduce battery efficiency. Ensure your laptop has proper ventilation and avoid using it on soft surfaces like beds or couches that can block airflow. Use a cooling pad if necessary.
  • Update software and drivers: Keeping your operating system and drivers up to date can improve battery performance. Updates often include optimisations and bug fixes that help manage power consumption more efficiently.
  • Manage background apps: Some apps run in the background and consume battery power.

Frequently asked questions

How do I know if my laptop battery needs replacement?
You can tell if your laptop battery needs replacement by checking for signs like reduced battery life, the battery not holding a charge, or unexpected shutdowns. Use built-in tools to check battery health: on Windows, generate a battery report using Command Prompt; on macOS, check the battery condition in System Information under Power. If the condition is listed as "Replace Soon," "Replace Now," or "Service Battery," it is time to consider a replacement.

What is a good battery cycle count for a laptop?
A good battery cycle count for a laptop is generally fewer than 300 to 500 charge cycles, depending on the manufacturer. A charge cycle is using 100% of the battery's capacity, not necessarily all at once. For example, using 50% of the battery one day and recharging it, then using 50% the next day and recharging it again counts as one cycle. Regularly checking your battery’s cycle count helps gauge its health and longevity.

Can I replace my laptop battery myself?
Yes, you can replace your laptop battery yourself if it has a removable battery. Purchase a compatible replacement and swap it out. For non-removable batteries, the process is more complex and may require special tools and skills. It is recommended to have a professional technician replace it to avoid damaging your laptop. Always refer to your laptop’s user manual or manufacturer’s website for specific instructions.

How long should a laptop battery last before degrading?
A laptop battery typically lasts between 2 to 4 years before it starts to degrade, depending on usage and care. Factors like frequent charging, high temperatures, and heavy usage can accelerate wear. To extend battery life, avoid letting it drain completely, keep your laptop cool, and use power-saving settings. Regularly checking battery health helps monitor its condition and prolong its life.
