Windows PCs come with tools to manage power consumption, notably the Power Settings Command-Line Tool (Powercfg.exe), which can generate a battery report. This report, saved as an HTML document, details battery usage, capacity, and historical data. Users can create a battery report by opening Command Prompt and entering specific commands. The report shows the design capacity and current full-charge capacity of the battery, helping track degradation over time.
The battery report also includes usage data over the past three days, allowing users to analyze which activities impact battery performance. The Battery Life Estimates section provides insights into potential battery longevity based on usage patterns. Windows 11 allows users to check app-specific power consumption through Settings > System > Power & Battery.
The Energy Recommendations checklist in Windows 11 offers energy-saving options and direct links to relevant settings. Users can adjust sleep and display settings according to their preferences. The Shutdown command can be executed from Command Prompt or the Run dialog box for transitioning between power states. The Battery Saver feature, now called Energy Saver in version 24H2, conserves battery life by disabling non-essential activities and can be manually activated.
