Wondering how to check your laptop’s battery life? By battery life I mean not the backup time of your battery but the life of your battery. Every laptop battery has a fixed total charge capacity which decreases over a period of time and hence your backup time is reduced. By knowing how much your battery capacity is degraded, you can easily predict the life of your battery. What’s more, you don’t even need any 3rd party tool for this as Windows already has an in-built tool for this!

STEP 1:

Open command Prompt and type “powercfg -ENERGY” without quotes as shown in the picture below and then press ENTER.

STEP 2:

Wait for 60 secs and a report will be generated. That’s it! Yes that’s it. Nothing else! The location of the report will be given in the command prompt window itself as shown below.

STEP 3:

Open the report from the location and scroll down to ‘Battery Information’ section. Check the screenshot below for help. Calculate your battery life using: (Last Full Charge / Design Capacity) * 100
