Tips for using iPad: Verify the authenticity of the device-open the "Settings" of the tablet, then click the "General" option, and then click the "About this computer" option. After entering, slide down the screen, then I can see the serial number of the tablet, and then copy this serial number.

1. Settings-Privacy-Diagnosis and dosage, remember to send it to the selection automatically.
2. Click on the diagnosis and dose data to find the latest date record file of log aggregation. Remember to look from the bottom up. In alphabetical order, Bian Xiao takes iPad mini3 as an example. The battery capacity data given by official website is 23.8Whr, which is about 6432mA when converted into milliamperes. Is it simple? Try it quickly!
After using iPhone/iPad for a period of time, you will find that the battery life is getting shorter and shorter. How can this be tolerated by low-headed people? Want to know how much battery capacity your iPhone has?
Today, I will share a little trick to teach you to test the health of the iPhone/iPad battery.
First find "Privacy" in the setting interface of the mobile phone, and click.
Pull down to the bottom, find "Diagnosis and Dose" and continue to click.
In the interface that appears after clicking "Diagnosis and Dose", select "Automatic Send", otherwise the diagnosis data will not be found. Then click "Diagnosis and Dose Data" to start the test.
In the data page, look for the log file of "Log-Aggregation-Latest Date". Take the iPhone 5s as an example, you need to find such a line of data (it is recommended to look up from the bottom).
In place; & lt/integer & gt； The middle data is the maximum battery capacity of the current battery. The battery capacity of the iPhone 5s was 1560mAh when it left the factory, but now it is 1500mAh, which is barely healthy.
There is little difference in the capacity of the middle 60mAh, but the lost battery capacity will definitely have a certain impact on battery life.
Little friends may wish to test your equipment!
Finally, send the battery capacity of each version of iPhone and iPad. Let's see if your battery is still healthy!
