Windows 10: how to monitor the battery health of a laptop 

To access and open the report, open a window of theFile explorer of Windows 10 then, in the left column, select This PC. Then enter the system disk (VS:), Open the directory Users, Then enter the repertoire with the name of your session.

Maintenance of your battery in Windows

Lithium-ion batteries are the most common type of battery used on today’s mobile devices, including laptops and tablets. These batteries are quickly loaded, unload at a regular rate and have a high energy density which reduces the size of the cells in the batteries.

By understanding a little more on lithium-lion batteries, you can help yourself optimize the autonomy of your battery and the overall regency of the battery of your device:

• The capacity of lithium-ion cells is reduced after a number of times the battery is loaded, then unloaded. This means that you will need to load your battery more often and that the overall battery capacity can be lower.
• When you use your device, make sure the battery unloads regularly within 50 %. This reduces deterioration in battery cells.

Lower battery capacity

When the battery capacity is lower, the battery cannot be loaded as much as it was in relation to the moment when it was more new. Therefore, the battery life can be reduced and you will have to recharge your battery more frequently.

Optimize battery integrity

Like all batteries, lithium-ion battery age and deteriorate over time and with use. To improve autonomy and battery performance, try to maintain the battery level between 20 % and 80 % several times a week instead of using your device for a short period, then plug it in to recharge the battery. If your device supports the smart load, activate it to make sure your device remains in charge of the recommended battery, even if you leave your plug-in.

When you use your battery, you should avoid certain conditions, as they can lead to battery degradation and faster aging:

• Try not to use your device or charge it at high temperatures. Extremely high temperatures can lead to the degradation of the device’s batteries at an accelerated speed, which can definitively reduce the battery capacity.
• Store your device with the battery loaded less than 50 % but not completely emptied. Batteries that are more busy and stored can lose capacity more quickly. If you need to store your device for a long time, it is best to make sure that the battery level is less than 50 %, but that it is not completely emptied before storing your device.

When a battery has degraded strongly, the battery life can be very short or the lithium-ion cells of the battery can extend. When a battery expands following a deterioration, this is most often due to the formation of carbon dioxide (CO2), an ininflammable gas. If the battery of your device has developed visibly beyond the mechanical case, we recommend that you stop using the device. You must handle the device carefully to avoid exerting pressure or drilling the battery cell.

Obtain a detailed battery report in Windows 11

If you want more technical information on using your battery and estimated capacity, you can use the PowerFg command line integrated in Windows 11 to generate a battery report.

1. Select Research In the taskbar, enter Command Prompt, Press for a long time (or right -click) on Command Prompt, Then select Execute as administrator >Yes.
2. At the command prompt, enter PowerCfg /Batteryreport, then press Entrance.

Up close to the health of your laptop battery by quickly generating a detailed autonomy report in Windows 10.

The battery life of your laptop seems to decline ? You can check this very easily under Windows 10 by generating a range of autonomy. Directly integrated into Windows, this feature requires going through the command prompt and allows you to obtain precious information on the battery of your machine. From the number of charging cycles to the remaining maximum capacity, including the history of the latest charges made, the autonomy ratio generated by Windows allows you to know very quickly if your battery is at the end of life and requires being changed.

1. Open the command prompt

Click on the Start menu, then in Windows System, launch the command prompt.

2. Generate an autonomy report

The command prompt should display, by default, C: USERS NAMEDREPC>.

This is where you have to enter the command to generate an autonomy report. To do this, type PowerCfg /Batteryreport and press Enter to validate.

The command prompt now indicates that the battery autonomy report is recorded in the directory C: USERS NAMEDREPC under the name of Battery-Report.html.

3. Access the report

To access and open the report, open a window of theFile explorer of Windows 10 then, in the left column, select This PC. Then enter the system disk (VS:), Open the directory Users, Then enter the repertoire with the name of your session.

Locate the named file Battery-Report And double-click the file to open it in the Edge web browser.

The autonomy report opens and allows you to display detailed information on the battery health of your machine, the number of cycles, the recent history of battery, etc.

How to know the health of an Android smartphone battery ?

In the settings of your smartphone, Android gives you several interesting information on the battery: what are the applications that consume the most energy, what is the duration of a complete autonomy cycle, how long does it remain on average before his mobile goes out, what is the duration for a complete recharging. Data that can be precious well used, but which are not relating to the state of battery health.

This information is hidden. It was also on iOS a short time ago, but an update added this feature following the Slotted iPhone affair to preserve the battery. However, checking the shape of its battery can be interesting, especially in the event that the autonomy of the smartphone melts as snow in the sun: problem of performance and optimization or battery which flanches, it is often hard to know what is wrong. And if we do not know the source of his concerns, it is then very difficult to resolve them. No need to change the battery of its mobile if it displays a capacity of 90% of the original volume for example.

Android secret code

Numerous Android information and features that are not planned for the general public can be accessible via a secret code. There are a dozen, that it is enough to type on the phone keyboard to reveal a hidden menu. One of these codes allows us to discover many technical elements on the smartphone, especially in terms of connectivity. but also on the battery.

Open your mobile phone application

Note that this code works on all Android smartphones, regardless of the overlay. But on some models, especially the most recent (from Android 8.0 Oreo), battery information does not appear in the list. If you are in this case, it will be more complicated to check the state of health of your battery, but not impossible. Please read the rest of this tutorial to find out more.

External application

If you have in your possession a recent or updated smartphone to a recent version of Android, and that the manipulation described above therefore does not work, you will have to turn to third-party applications.

Ampere

The great strength of the Ampere application, downloadable for free on the Play Store, is its extreme simplicity. Download it and it will tell you after a very fast diagnosis the approximate state of battery health: good, bad. No precise figure, but it allows you to get an idea. The app also measures the amperage when the smartphone is loaded, which can be useful for comparing the power of different chargers.

CPU-Z

CPU-Z is a very practical and known software on Windows to know with precision the hardware of his PC. An equivalent has been developed for Android mobiles, and it is just as effective. Information on the SOC, the screen or the RAM of the device, the application tells you everything. And this is also the case on the battery: temperature, voltage, state of health, no need to go further, the data is here.

Accubattery

It is by far the most complete and precise application that we offer here. But it requires a little more effort from users, and especially time. This is why ampere and CPU-Z are interesting: they do not require any action on your part and you have a result directly. Accibattery is advised to those who wish to go further.

The application gives you advice to optimize the health of your battery, such as recharging your smartphone until 80% and not 100%. It also indicates essential data such as voltage, temperature, load cycles and discharge. The tool is more complete than that natively integrated into Android in the matter. And above all, after several days of use and refills, the app is capable of calculating fairly precisely what is the real capacity of the mobile battery, and therefore if it has lost a lot since the purchase or not. To go further, you can also compare chargers thanks to the measurement of the load speed and take advantage of many other audit options.
