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 now the most important question arises: “How to check the phone’s battery capacity ?” Let's look at this and check our smartphones.
How to check the battery capacity of the phone?
Now on Google Play you can find many applications that show the approximate battery capacity of your smartphone. Unfortunately, it’s quite difficult to get the exact values, so you should 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 and process everything. The Nova Battery Tester application quickly and accurately determines the battery capacity. With this utility you will know the battery capacity after 2 hours.
When you first start the application, the Internet on your phone should be turned on. Why is this needed? The program will take all the necessary information about your smartphone from the Internet. She has her own online database, where she draws information about what current consumption is on your device.
Perhaps your device will not find the application in its database. This is happening with new mobile devices. You can find all the necessary information and add your smartphone to the database, for this you will need to fill in the main fields. Of course, you will need to turn on the Internet.
How to use the application?
So, your device is present in the database of the selected utility, and there is an opportunity to get the necessary information about it. If you have met all the necessary criteria, then you can proceed to determine the battery capacity.
- First, charge or discharge the battery of your smartphone up to 70 percent.
- Next, run the desired utility and click on the “Download Features” button to get data about the mobile device from the database.
If the phone is in the list, the program will quickly download the necessary data about it. Otherwise, it will give a warning that the test result will be incomplete and inaccurate.
After testing, you can send the result to the developers, and they will add your device to the “Tested” column. To do this, after viewing the result, you must click on the "Send result" button.
- Go to the application menu, then to the settings. Select the item "Test Options", then mark the sub-item "Quick".
- To get a more accurate result, you need to turn off the Internet on your phone. For the test, the maximum screen brightness will be automatically set.
- Next, click on the "Run Quick Test" button and wait for it to complete. 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 observe the results, with each change, the capacity that the program measures will be averaged. At the end, it displays the 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 line “Seconds per division”, you can see how much one percent of your battery was missing.
Battery Monitor Widget App
Unfortunately, the previous application allows you to determine a very approximate battery capacity, but does it quickly. Battery Monitor Widget allows you to find out the battery capacity much more accurately, but it takes more time. This application itself calculates the charge and discharge current of a mobile device - the main component that allows you to determine the capacity.
Program setting
How to check the battery capacity of the phone? When you start this program, you will automatically be prompted to go to settings. Next, you need to follow the basic procedure:
- The first parameter is current detection. You need to select "Automatic".
- Next, indicate the battery capacity that the manufacturer wrote. You can see it on the battery itself or find this indicator in the instructions.
- You also need to choose a method that allows you to get data into the application. To more accurately assess the capacity, you need to select the item that produces the data as often as possible. But this makes the smartphone work more, so the phone will run out faster. It is better to select “Default” or “Every minute while charging”. So you get enough accurate data and do not refuse the comfortable operation of a mobile device.
- In the last step, you need to click on the button "Show mA in history."
How to check the battery with a multimeter?
It is quite difficult to measure the battery capacity with a multimeter, it can even be said impossible. This conclusion follows from the fact that a fully charged battery must be connected to the multimeter. Next, you will use this device to find out the consumption of the device (current). It is also necessary to detect the time during which the battery is completely discharged.
How to check the battery with a multimeter? After obtaining the necessary indicators, you can calculate the capacity according to the well-known formula: capacity = current * time.
How to measure the necessary indicators with a multimeter? Everything is a bit more complicated here. To obtain accurate readings, direct current is required. 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.
Output
How to check the battery capacity of the phone? To do this is quite simple, but you need to be patient, because to get a more accurate value, you need to spend a lot of time. If your phone runs out of power quickly, then it’s probably not even the fact that the manufacturer has deceived you, but simply the battery has a small capacity for your smartphone. High capacity battery is an excellent solution to this problem.
