How to Checks laptop battery health: Run battery report
The Battery Report tool is hidden just below the surface of Windows 10, but it’s easy to use when you know where to look. O trick is to use the Windows command prompt – here’s how:
- Open the Start menu by clicking on it (or pressing the Windows key on your keyboard) and launch Command Prompt. The easiest way to do this is to simply start typing “Command Prompt” into the search box – it should appear near the top of your search results quickly. If that doesn’t work, you can manually scroll through the Start Menu application list and find the Command Prompt in the Windows System section. Click on the Command Prompt application to launch it.
- After opening the Command Prompt, you’ll see a black window with white text spelling out a command line – probably starting with C: and ending with your Windows username. Now it’s time to get to work: type powercfg / batteryreport (make sure there’s a space between the two terms) and press Enter.
- Assuming everything went well, you will see a message at the command prompt informing you that a battery report has been saved in your user folder. Great job!
- Now you need to find this report and read it. The quickest way is to open File Explorer (if you can’t find it, type “File Explorer” into the Start Menu search box) and navigate to the folder where Command Prompt reported that your battery report was saved. By default it is your user folder (C: Users [yourusernamehere]), but if you can’t find the battery report there, you can also try searching your hard drive for it. Just open Start Menu again and type battery report to start a search.
If it doesn’t show up up immediately, wait a few minutes (Windows sometimes takes time to register new files and index them for search purposes) and try your search again.
- Open the battery report and have a look! It will be saved as an HTML file, so Windows should automatically open it using a web browser. The report should look like a long list of information, including battery life estimates and battery usage reports.
Once you have a copy of your Windows laptop battery report, you should have all the information you need to diagnose your battery’s health. laptop.
How to Checks laptop battery health: what to look for
The fastest way to find out how long your laptop battery can last, skip down to the Battery Life Estimates section of your newly created battery report. There, you’ll see estimates of how long your battery should last, based on how you’ve used it in the past.
Keep in mind that these are imperfect auto-generated estimates, so you’re likely to see some weird math or confusing numbers as you scroll down the list, especially if you’ve used the laptop erratically recently or left it unused for long periods of time.
The most important things to note are the numbers under the Active heading: these are estimates of how long your battery would have lasted based on your laptop usage, formatted as hours, minutes, seconds.
Also note that there are two columns of active battery life estimates: Fully charged and At design capacity. They are important because they estimate the difference between your laptop’s battery capacity now and when it was new.
At full charge, active time is an estimate of how long your laptop battery can last based on its current capacity, while At Design Capacity is an estimate of how long your laptop battery could have lasted when it was new from the factory.
You can also get some useful insights from the Battery Capacity History section of the battery report. You can find it in the middle of the report and it provides a dated list of Total Load Capacity measured against project capacity.
Full charge capacity is a measure of how much power the battery actually holds, and design capacity is the amount of power it is designed to support. So, over time, you should see the total charge capacity decrease compared to the project capacity as your laptop battery ages and loses its ability to hold a charge. Once Your Laptop If your company’s total carrying capacity drops 25% to 50% below its designed capacity, it’s probably time to start thinking about a replacement.
How to Checks laptop battery health: test the battery yourself
If the battery life estimates section is not giving a satisfactory picture of how healthy your laptop is, you can test the battery yourself and use the Battery Report to measure the results. See how:
- Generate a battery report (as described above) and see the battery usage section: see how it shows a graph of how your battery has been used in the last few days? You can use this to measure exactly how long your battery can last a full charge, but you’ll have to charge it. up fully and then drain it straight to zero without letting it hibernate or sleep.
- First, turn off laptop maximum automated power conservation from features how can you find. Most notably, disable sleep and hibernation features, which you can find in the Power and suspend section of the system settings. The quickest way to find out is to type “Power” into the Start menu.
- Come now up with a plan for how you will use the laptop continuously until off. Ideally, you should just use it as you normally would all day, until the battery runs out, but that might not be practical – especially if your laptop still lasts more than 8 hours on a single charge. Alternatively, you can mute the laptop and set it to play a 24-hour YouTube video or start a game and let it run all day.
- Now load your laptop up to full power and disconnect it from the charger, start the test of your choice and leave the laptop run until it automatically shuts down. Once turned off, plug it in again and let it charge up until you can turn it back on, then generate another battery report using the process described above. You should see a new entry in the Battery Usage section, which reveals how long the laptop lasted (under whatever workload you assigned) with a full load.
Performing these steps provides a good way to get a up- updated idea of how long your laptop can last with full charge. You can run this test every few months to keep track of your laptop battery health or experiment with different workloads (an entire day surfing the web and emailing vs. an entire day watching movies or playing games, for example) to get a better sense of which activities drain your laptop battery the most fast.
