How can I check the battery capacity of my phone? Testing and determining the actual capacity of the battery

All modern smartphones, unfortunately, are quickly discharged. The mobile device can be charged several times a day, since the battery capacity does not allow you to comfortably use the gadget for a long time. Because of this, many people doubt the real capacity of the battery. And here comes the most important question: "How to check the battery capacity of the phone?" Let's look at this and check our smartphones.

How can I check the battery capacity of my phone?

Now on Google Play you can find many applications that will show the approximate capacity of your smartphone's battery. Unfortunately, it is difficult to get exact values, so do not count on it. How do they work? After several cycles of charging and discharging the battery, they will show its capacity. Of course, it should take a lot of time for the application to track everything and process it. The Nova Battery Tester application quickly and qualitatively determines the battery capacity. With this utility you will know the capacity of the battery after 2 hours.

When you first start the application, the Internet on your phone should be turned on. Why is this necessary? All the necessary information about your smartphone the program will take from the Internet. She has her own online database, where she draws information about what current is consumed on your device.

Perhaps your device does not find the application in its database. This happens with new mobile devices. You can find all the necessary information and add your smartphone to the database, you will need to fill in the main fields. Of course, you will need to turn on the Internet.

How do I use the application?

So, your device is present in the database of the chosen utility, and there is an opportunity to get the necessary information about it. If you have met all the necessary criteria, you can proceed to determine the capacity of the battery.

• First, charge or discharge the battery of your smartphone to 70 percent.
• Next, run the desired utility and click on the "Load Characteristics" button to get data about the mobile device from the database.

If the phone is present in the list, the program will quickly download the necessary information about it. Otherwise, it will issue a warning that the result of the test will be incomplete and inaccurate.

After testing, you can send the result to the developers, and they will add your device to the "Tested" box. To do this, after viewing the result, click on the button "Send result".

• Go to the application menu, then go to the settings. We select the item "Test Options", then we mark the sub-item "Quick".
• To get a more accurate result, you need to disconnect the Internet on your phone. For the test, the maximum brightness of the screen will be automatically set.
• Then click on the button "Run a quick test" and wait for its completion. First, the utility will "warm up" the device, while we lose about 5 percent of the charge.

After that, there will be testing itself, which will last until the battery charge drops to 12 percent.

While the application is running, you can monitor the results, with each change the capacity that the program measures will be averaged. In the end, it displays an average value. It is because of this that it is difficult to hope for an absolutely accurate result.

Also, when viewing the result in the "Seconds per division" line, you can see how much one percent of your battery was enough.

Battery Monitor Widget application

Unfortunately, the previous application allows you to determine a very approximate battery capacity, but does it quickly. Battery Monitor Widget allows you to more accurately know the battery capacity, but it takes more time. This application calculates the charge and discharge current of the mobile device itself - the main component, which allows you to determine the capacitance.

Setting up the program

How can I check the battery capacity of my phone? When you run this program, you will automatically be asked to go to the settings. Then you need to perform the basic procedure:

1. The first parameter is current detection. You need to select the "Automatic" item.
2. Next, indicate the capacity of the battery, which the manufacturer wrote. This can be viewed on the battery itself or find this figure in the instructions.
3. You also need to select the method that will allow you to get the data into the application. To more accurately estimate the capacity, you need to select the item that produces the data as often as possible. But this causes the smartphone to work more, so the phone will be discharged faster. It is better to select the "Default" or "Every minute while charging" item. So you get enough accurate data and will not give up the comfortable operation of the mobile device.
4. At the last step you need to click on the button "Show mA in history".

How to check the battery with a multimeter?

Measuring the battery capacity with a multimeter is quite difficult, even impossible to say. This conclusion follows from the fact that a fully charged battery must be connected to a multimeter. Next, you will use this device to recognize the device's consumption (current). It is also necessary to detect the time for which the battery is completely discharged.

How to check the battery with a multimeter? After obtaining the necessary parameters, you can calculate the capacitance according to the known formula: capacitance = current strength * time.

How to measure the required parameters with a multimeter? Here everything is a bit more complicated. To obtain accurate indicators, you need a constant current. This is difficult to achieve, and it must be maintained until it is completely discharged, which is quite difficult. This can only be done in the laboratory.

Conclusion

How can I check the battery capacity of my phone? To do this is simple enough, but you need to be patient, because to get a more accurate value, you need to spend a lot of time. If your phone is quickly discharged, then maybe it's not even that the manufacturer cheated on you, but simply the battery has a small capacity for your smartphone. A high-capacity battery is an excellent solution to this problem.
