How to Generate a Battery Report in Windows 10
The battery on your Windows 10 laptop or tablet is one of its most critical pieces of hardware. Over time, a battery’s life span shortens, and its ability to hold a charge decreases. If you suspect your battery’s performance is fading too quickly, use a built-in feature to create a battery report. The report is saved as an HTML file that you view in a web browser and includes data on your system, all installed batteries, usage, capacity history, and battery life estimates.
Check Battery Health in Windows 10
With your battery report generated and open, it’s time to go through each section to gain a clearer picture of your battery’s performance, and estimated life expectancy. The first section, directly under Battery Report, lists some primary system information such as your computer’s name, BIOS version, OS build, and the date the report was created. The second section, below Installed batteries, lists key information about your laptop or tablet batteries, such as name, manufacturer, serial number, chemistry, and design capacity.
Recent Usage
This section gives you a detailed overview of when your device was either running on battery or connected to AC power. Recent usage covers your device’s power states for three days and includes start time, state (active/suspended), source (battery/ac), and capacity remaining.
Battery Usage
This area lists any battery drains over the last three days before generating the report. If your system ran for extended periods on battery alone, this section would break it down by start time or duration, as well as by energy drained.
Usage History
Under this section, you’ll see a complete history (including duration) of each time your device was running on either battery or AC power. Reviewing your usage history is a great way to see how often and for how long you run your device on battery power.
Battery Capacity History
In this section of the report, you see full charge capacity compared to your battery’s design capacity for each period. Watching your full charge capacity is another helpful way to monitor the overall health and performance of your battery over time.
Battery Life Estimates
The final section of the report displays battery life estimates at full charge, compared to the designed capacity. This area gives you a clear outlook of how well your battery’s life is holding up over time. At the very bottom of the report, there is an estimated battery lifetime value, based on observed drains since the last OS installation.
