Windows laptops have a useful but unheralded characteristic that can assistance you lot diagnose the health of your bombardment. It's called the Battery Report tool, and in this article we're going to show you how to utilize it to get the nearly out of your laptop.
How to check laptop battery health: Run Battery Report
The Bombardment Study tool is hidden only below the surface of Windows 10, but information technology's easy to use once you know where to expect. The pull a fast one on is to use the Windows control prompt — here's how:
1. Open the First menu by clicking information technology (or past pressing the Windows key on your keyboard) and launch the Control Prompt.

3. Bold everything went smoothly, you should see a message in the Control Prompt informing you that a bombardment report has been saved to your user folder. Great piece of work!
iv. Now you need to notice that report and read it. The fastest way is to open File Explorer (if you can't notice it, blazon "File Explorer" in the Start Menu search box) and navigate to the folder where the Command Prompt told you your bombardment report was saved.
By default this is your user folder (C:\Users\[yourusernamehere]\), but if you can't find the battery report in that location you can too try searching for it on your hard drive. Just open up the Start Menu once more and type battery report to start a search.
If it doesn't evidence up right away, wait a few minutes (Windows sometimes takes time to register new files and index them for search purposes) and then attempt your search again.
5. Open the battery report and accept a look! It will be saved as an HTML file, so Windows should automatically open up it using a spider web browser.
The report should await like a long list of information, including battery life estimates and battery usage reports.

Also, note that there are two columns of Agile battery life estimates: At Full Charge and At Design Capacity. These are important because they gauge the divergence between your laptop's battery capacity at present and when it was brand-new.
At Full Accuse active time is an estimate of how long your laptop'south battery tin concluding based on its current capacity, whereas At Design Chapters is an judge of how long your laptop'due south battery could take lasted when it was fresh from the mill.
You can also get some useful insights from the Bombardment capacity history section of the battery written report. Yous can discover it midway through the report, and it provides a dated list of Full charge capacity measured against Design chapters.
Full charge capacity is a measurement of how much power the battery actually holds, and Pattern chapters is how much power it was designed to agree. Thus, over time you should see Full charge capacity diminish compared to Design capacity as your laptop's battery ages and loses the ability to hold a charge. Once your laptop'south full charge capacity reliably drops 25%-fifty% beneath its design capacity, information technology'southward probably time to start thinking about a replacement.

At present charge your laptop upwardly to full power and disconnect information technology from the charger, start your examination of option, and allow the laptop run until it shuts off automatically. One time it'southward off, connect information technology to power again, permit information technology charge up until you can turn information technology dorsum on, then generate another bombardment report using the procedure outlined above. You should see a new entry in the Battery usage section which reveals how long the laptop lasted (nether any workload yous gave information technology) on a full accuse.
