Useful information in battery reports
First, you will see a brief summary of important information about your computer and the battery.
- DESIGN CAPACITY: This is the battery design capacity. Displays the maximum capacity of the Battery.
- FULL CHARGER CAPACITY: Shows the maximum capacity of fully charged Battery at the present time.
Based on the above two values, you can easily see that the capacity of the battery has decreased over time. Or with a new battery that you see is too large deviation, the battery may be defective, damaged, old, and you should contact the seller of the machine.
Continuing in the Battery capacity history section, you will see information about the previous battery charge saved. However, if you reinstall Windows, you will lose all the previously collected data.
Scroll down to the Battery life estimates section . In this section you will see the estimated value of battery life. Note, this is not really accurate because the battery life depends a lot on your usage. For example, screen brightness, wifi on, processor, etc.
With that value you can estimate the battery capacity. This value can be queried at any time via the system tray icon.
