Windows laptops take a useful only unheralded feature that tin can help you diagnose the wellness of your battery. It's called the Battery Report tool, and in this commodity we're going to show you how to use it to get the nigh out of your laptop.
How to cheque laptop battery wellness: Run Battery Report
The Battery Study tool is subconscious merely beneath the surface of Windows 10, merely it'due south easy to apply one time yous know where to look. The trick is to use the Windows command prompt — here's how:
i. Open the Get-go bill of fare by clicking it (or by pressing the Windows key on your keyboard) and launch the Control Prompt.
The easiest way to practice that is to but first typing "Command Prompt" into the search box — it should appear near the tiptop of your search results pretty chop-chop.
If that doesn't work, you tin manually scroll down the Start Menu's app list and discover Command Prompt nether the Windows System section. Click the Control Prompt app to launch it.
2. Once you lot have the Control Prompt open you should see a black window with white text spelling out a command line — likely starting with C: and catastrophe with your Windows user name.
Now it's time to go to piece of work: type powercfg /batteryreport (brand sure there's a space between the two terms) and printing Enter.
3. Bold everything went smoothly, you lot should see a bulletin in the Command Prompt informing yous that a battery study has been saved to your user folder. Great piece of work!
iv. Now you need to notice that report and read information technology. The fastest way is to open up File Explorer (if yous can't find information technology, blazon "File Explorer" in the Kickoff Carte search box) and navigate to the binder where the Command Prompt told you your battery written report was saved.
By default this is your user binder (C:\Users\[yourusernamehere]\), but if y'all can't detect the battery report there yous can also try searching for it on your hard bulldoze. Merely open the Start Carte du jour again and type bombardment written report to start a search.
If it doesn't prove up right away, look a few minutes (Windows sometimes takes time to register new files and index them for search purposes) then try your search once again.
5. Open the bombardment report and accept a look! It will be saved equally 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's bombardment written report, you lot should have all the data you demand to diagnose the battery health of your laptop.
How to check laptop bombardment health: What to expect for
The quickest way to get a handle on how long your laptop's battery can last is to skip down to the Bombardment life estimates department of your newly-created battery report. In that location, you lot'll see estimates of how long your battery should last, based on how yous've been using it in the past.
Proceed in mind that these are imperfect auto-generated estimates, so you lot're probable to see some strange math or confusing figures equally you scroll downward the list, especially if you lot've used the laptop erratically recently or have left it unused for long periods of time.
The most important things to pay attending to are the numbers under the Active heading: these are estimates of how long your battery would take lasted based on your laptop usage, formatted as hours, minutes, seconds.
Also, note that there are two columns of Agile bombardment life estimates: At Full Charge and At Design Capacity. These are important because they estimate the difference between your laptop's battery chapters now and when it was brand-new.
At Full Accuse active fourth dimension is an guess of how long your laptop's bombardment can last based on its current capacity, whereas At Design Chapters is an judge of how long your laptop's battery could have lasted when it was fresh from the manufactory.
You can also go some useful insights from the Battery capacity history section of the battery report. You tin discover information technology midway through the report, and it provides a dated list of Full accuse capacity measured against Design chapters.
Full charge capacity is a measurement of how much power the battery really holds, and Design capacity is how much power it was designed to hold. Thus, over time you should see Full charge capacity diminish compared to Design capacity equally your laptop's battery ages and loses the power to hold a accuse. Once your laptop's full charge chapters reliably drops 25%-50% below its design capacity, it's probably time to start thinking about a replacement.
How to cheque laptop battery health: Examination the battery yourself
If the Battery life estimates section isn't giving you a satisfying picture of how healthy your laptop's battery is, you lot tin exam the battery yourself and use Battery Study to measure the results. Here's how:
1. Generate a Battery Report (as outlined higher up) and look at the Battery usage section: meet how it shows you a chart of how the battery was used over the by few days?
You lot can utilise this to measure exactly how long your battery can concluding on a full charge, but you'll take to charge it up to full and then drain it straight down to zero without letting it hide or get to slumber.
ii. First, shut off every bit many of your laptop's automated power-conservation features every bit you tin find. Most notably, disable the sleep and hibernation features, which you should be able to observe in the Power & sleep section of your System settings. The quickest manner to find this is to type "Power" in the Starting time Menu.
three. At present come with a plan of how you're going to apply the laptop continuously until it shuts off. Ideally you should just utilise information technology equally yous normally would all day, until the battery runs out, but this might non be practical — peculiarly if your laptop still lasts 8+ hours on a single charge. Alternatively, y'all could mute the laptop and gear up it to play a 24-hour-long YouTube video, or launch into a game and exit it running all twenty-four hour period.
4. At present charge your laptop up to full ability and disconnect information technology from the charger, start your test of option, and let the laptop run until it shuts off automatically. One time it's off, connect it to power again, let information technology accuse up until you can turn it back on, then generate another battery written report using the process outlined above. You should see a new entry in the Battery usage section which reveals how long the laptop lasted (under whatever workload you gave it) on a full charge.
Performing these steps provides a good way to go an up-to-date idea of how long your laptop can terminal on a full charge.
You can run this exam every few months to keep tabs on your laptop battery's health, or try it with dissimilar workloads (a total twenty-four hour period of web browsing and emailing vs. a full day of watching movies or playing games, for example) to get a ameliorate sense of which activities bleed your laptop's battery the fastest.
