Is it Time To Replace Your Laptop or Smartphone Battery?

No matter how you take care of you battery,  it will degrade over time and give you less battery life over time as it looses capacity. Even when you remove it and keep it in a drawer,  it will still degrade.

You don’t have to wait for your device to warn you when your battery’s health is in critical condition. You can check your battery’s health from time to time so that you plan a replacement in advance if necessary.

You might not notice your battery degradation until it has degraded enough for you to notice that you’re coming 2 or 3 hours short of the battery life you used to get.  Here’s how you can get a detailed report on the state of your battery whenever you want.


Versions of Windows prior to Windows 7 don’t have the feature to alert you when you your battery’s health was critical. The more advanced Windows 7, 8 and 10 should give you a notification in the system tray.
