As laptops age, their battery life tends to decrease, leading to shorter usage times between charges. To assess your laptop's battery health on Windows 10 or 11, follow this guide for a straightforward evaluation. Regardless of your laptop's brand (ASUS, Lenovo, HP, HUAWEI, etc.), you'll learn three simple methods to check its battery condition and determine if a replacement is necessary.
Step 1: Open your laptop manager by typing its name in the search box. The example below uses Lenovo Vantage.
Step 2: Navigate to the battery page to check your battery health.
The second method involves using third-party system inspection software like AIDA64, BatteryInfoView, or BatteryBar.

For detailed insights, you can Generate a Laptop Battery Report. The next section explains how to interpret this report.
The battery report provides comprehensive information, including Installed Batteries, Recent Usage, Battery usage, and Battery capacity history. Two key figures under the Installed battery section are crucial: Design Capacity and Full Charge Capacity. If the Full Charge Capacity is less than half of the Design Capacity, consider replacing your laptop's battery. You can also calculate the battery health using the formula:
Battery Health = (Full Charged Capacity/Design Capacity)*100%
For instance, with a Design Capacity of 48944mWh and a Full Charge Capacity of 25992mWh, the calculated Battery Health is approximately 53%, indicating the need for a battery replacement.
This guide has outlined three effective methods to check your laptop's battery health on Windows 10/11. By assessing your battery's condition, you can decide whether a replacement is necessary. We hope this information helps you maintain your laptop's performance.
