How to check the battery status of your laptop
Battery life is often an ambiguous and ambiguous concept. In theory, it can be represented by a single number, but in reality, literally hundreds of factors can reduce or extend durability.It’s frustrating when trying to measure the battery life and status of a notebook, especially when trying to determine if it’s time Buy a new laptop..
Windows has a secret feature called Battery Reporting. This is what you use when testing the durability of your notebook at PC World. Here’s how to access the Battery Report to understand what you can find out about laptops:
How to create a battery report
Battery reporting isn’t a new feature, but it’s under the radar because there’s no way to access it from the Windows settings menu. Battery reports can only be created from the command prompt. Method is as follows.
- Run Windows Search CMD also command prompt.. A command prompt is displayed, displaying the search results. Open it.Or Windows[スタート]Of the menu[Windowsシステム]You can also find the command prompt under.
- When opened, you will see a command line starting with C: and ending with the name of your user account. A blinking cursor appears at the end of this command line.type powercfg / batcheryreport Press input With the keyboard.
- If successful, the command prompt will notify you that the battery life report has been saved to your user folder.
- Navigate to the folder listed at the command prompt. This will be the default user folder. This is C: Users
To access the Battery Report, use File Explorer to navigate to your user folder or perform a Windows search. Battery report.. Keep in mind that File Explorer can be faster, as it may take a few minutes for Windows Search to be able to index and search new reports.
The Battery Report is saved as an HTML document so you can open it in your web browser of your choice. Open it and you’ll find a long document full of information. Here’s how to decipher the meaning of each section:
How to estimate battery life using the Battery Report
Battery reports can be used to measure battery life in several ways, but most people scroll to the bottom of the report and Battery life estimate section.
It makes calculations to calculate battery life based on daily or weekly battery usage. Estimates are convenient because you don’t have to drain the battery completely.
Look at the Active column under At Full Charge. This will display the results formatted in hours, minutes and seconds. For example, if the column shows 4:56:22, it means that the battery was estimated to last for 4 hours, 56 minutes, and 22 seconds.
It also displays a log list for full charge and design capacity. The At Full Charge column is a cautionary estimate because it makes an estimate based on the maximum amount of charge the laptop battery can currently handle.
The At Design Capacity column makes an estimate based on the maximum battery charge when the laptop is new. This is a handy comparison of older laptops.
The log is not complete. It is estimated based on past battery usage and will be turned off if you change your PC usage in the future. Even small changes, such as switching the web browser used, can delay the quote.
The calculation of the battery report is also a bit … it can prove strange. If the system is used for a short period of time, or if it is used in short bursts throughout the day, an error will be displayed. Also, if you do not use the system at all for several weeks, you may get an error.
How to measure battery life using battery reports
You can get an estimate of battery life at a glance, but if you want accurate results, you need to dig deeper.
See the battery usage section of the report. This shows how the battery was actually used in the last 3 days. You can use these snippets to stitch battery life together, but that’s difficult.
To record accurate results, the laptop should discharge the entire battery at once. You can do this when you normally use your laptop, but it’s easier to use videos, scripts, or benchmarks that you can run unattended. Here are some suggestions:
- YouTube video over 10 hours long.
- use Basemark Web3.0 Benchmark.. Review the benchmark configuration options and turn on battery life mode. This causes the benchmark to loop indefinitely.
- use iMacros Create a custom web browsing macro and use the loop feature to run the macro until the battery is drained.
- Use a program like the following Macro recorder Create a loop that repeats indefinitely.
It also turns off all sleep and hibernate features, including the ability to turn off or dim the display.
Start the test of your choice and wait for your laptop to reach critical battery status. The power will be turned off automatically. Connect your laptop to a power source, turn it on, and run the battery report again.Of the report[バッテリー使用量]The section shows the durability of the battery.
Running this test gives an accurate baseline of durability. You can compare it to similar tests by others who own the same system, or run monthly tests to see how battery life is maintained over time.
How to measure battery status using Battery Report
The Battery Report provides two more ways to determine if a battery is on a hill.
The first is the cycle count. This is at the top of the report. Installed battery.. The cycle count is an estimate of the number of times the laptop’s full battery capacity has been discharged.
This is cumulative. One cycle means that the battery has been discharged 20 percent 5 times, or 100 percent once. A typical laptop battery needs to handle hundreds of charge cycles before a meaningful change in battery capacity occurs. In most cases, it can handle 500-1,000 cycles before battery capacity becomes an issue.
You can also look up Battery capacity history A section was found in the middle of the report. This will provide a log of the measured battery capacity. Also, for convenience, the design capacity of the battery is displayed. This is the amount of power the battery needs to hold if it works as intended.
Many new laptops show a full charge capacity that is slightly higher than the design capacity, but as the battery ages, the full charge capacity decreases. For example, the laptop above is approaching his 10th birthday.
A full charge capacity that is 20% lower or lower than the original design capacity indicates an old battery. However, nothing prevents the battery from dropping to the ground. Modern laptop batteries will be completely non-functional long before the full charge capacity reaches zero.
