When owning a laptop, one of the most important things to know is how to check the battery health of your device.
Checking the battery health may mean the difference between forking out hundreds on a brand-new device, or just spending less than $100 on a battery to refresh your laptop.
While checking the battery health of your laptop isn’t as simple as just opening your settings, it’s not very hard either. You don’t require any additional software, or even an internet connection.
Generating a battery report also provides you with a wealth of other information regarding your device’s battery making it useful for more than just checking the battery health.

Scroll down to the Battery capacity history section. Here you can find the current full charge capacity on the left-hand side and the original charge capacity on the right-hand side.
Find today’s date to see what the current capacity is. The lower it is compared to the original, the more unhealthy your laptop battery is.
Final thoughts on how to check the battery life of a laptop
As devices age, the battery will slowly decrease in full capacity meaning you won’t get the same power (and therefore length of time you can use the laptop when not plugged in) from a full charge the way you used to.
Keeping an eye on your laptop’s battery health can be a good way to monitor whether or not you need to replace the battery.
