All modern smartphones, unfortunately, are quickly discharged. The mobile device can be charged several times a day, as the battery capacity does not allow comfortable use of the gadget for a long time. Because of this, many people doubt the actual capacity of the battery. And now the most important question arises: “How to check the battery capacity of the phone?” Let's review it and check our smartphones.
How to check phone battery capacity?
Now there are many applications on Google Play that will show the approximate battery capacity of your smartphone. Unfortunately, it is quite difficult to get exact values, so you should not rely on it. How do they work? After several cycles of charging and discharging the battery, they will show its capacity. Of course,a lot of time should pass for the application to track and process everything. The Nova Battery Tester application determines the battery capacity quite quickly and qualitatively. With this utility, you will know the battery capacity in 2 hours.
When you first launch the application, the Internet on your phone must be enabled. 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.
Your device may 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, 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 app?
So, your device is present in the database of the selected utility, and it is possible 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 your smartphone battery to 70 percent.
- Next, run the desired utility and click on the "Download characteristics" button to get data about the mobile device from the database.
If the phone is on the list, the program will quickly download the necessary data about it. Otherwise, it will issue a warning that the test result will be incomplete and inaccurate.
Aftertesting, 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 "Submit 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. The screen will automatically be set to maximum brightness for the test.
- Next, click on the "Run a quick test" button and wait for it to complete. First, the utility will “warm up” the device, while we will lose about 5 percent of the charge.
After that, there will be a test itself, which will last until the battery charge drops to 12 percent.
While the application is running, you will be able to observe the results, with each change, the capacity that the program measures will be averaged. At the end, it will output 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 "Seconds per division" line, you can see how much one percent of your battery lasted.
Battery Monitor Widget app
Unfortunately, the previous application allows you to determine a very approximate battery capacity, but it 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 current andthe discharge of a mobile device is the main component that allows you to determine the capacity.
Program settings
How to check the battery capacity of the phone? When you start this program, you will automatically be prompted to go to the settings. Next, you need to follow the basic procedure:
- The first parameter is the current definition. You need to select "Automatic".
- Next, indicate the battery capacity, which was written by the manufacturer. You can see this on the battery itself or find this indicator in the instructions.
- You also need to choose a method that will allow you to receive data in the application. To more accurately estimate the capacity, you need to select an item that fetches data as often as possible. But this makes the smartphone work harder, so the phone will run out faster. It is better to select "Default" or "Every minute while charging". So you get fairly accurate data and do not give up on the comfortable operation of your mobile device.
- At the last step, click on the "Show mA in history" button.
How to check the battery with a multimeter?
Measuring battery capacity with a multimeter is quite difficult, one might even say impossible. This conclusion follows from the fact that a fully charged battery must be connected to a multimeter. Further, using this device, you will find out the consumption of the device (current). It is also necessary to note the time during which the battery is completely discharged.
How to check the batterymultimeter? After obtaining the necessary indicators, you can calculate the capacitance using the well-known formula: capacitance \u003d current strengthtime.
How to measure the necessary indicators with a multimeter? Everything is a little more complicated here. To get accurate readings, a constant current is needed. 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 to check the battery capacity of the phone? This is quite simple to do, 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 perhaps it’s not even that the manufacturer has deceived you, but simply that the battery has a small capacity for your smartphone. A high capacity battery is a great solution to this problem.
