While you can swap out the battery on many desktops, most laptops are not easily upgradeable, making the health of the one built-in even more important. Windows 10’s battery report tool lets you monitor it, providing detailed information on what current battery life is like and how it’s changing over time. However, it’s not listed in Settings or anywhere, so you might not be aware that the feature actually exists.
How to create a battery report on Windows 10
Before starting, make sure you’re logged in to your Windows 10 PC with the administrator’s account. This will make the process as smooth as possible. There’s lots of information here, but there are a few key metrics to look for. The ‘Battery usage’ graph and table gives an indicator of how long it’s taken for the battery to deplete, including when on standby.
‘Battery life estimates’ compares how long you’re getting from a charge compared to how it was when new. This can be an effective way of knowing whether it needs replacing soon.
There’s also ‘Battery capacity history’, which compares current full charge capacity with the capacity as designed by the manufacturer. The laptop used below is very new, so full charge capacity is actually higher than designed.
A ‘report time’ is listed at the top of the file, but it won’t update automatically. We’d recommend carrying out a battery report every six months or so to see how the situation is progressing.
Can you create a battery report on macOS?
Not exactly, although recent versions of macOS do give a more brief overview of some key battery statistics. These include how many cycles the battery has been through, system power settings and an indicator of battery capacity as a percentage of the original. To access it, click the Apple icon in the top left of the screen and choose ‘About this Mac’. In the window that appears, click the ‘System Report…’ button and select ‘Power’ from the left pane.
