2. Open the phone settings, drop down in the settings interface and click "Privacy" to enter the privacy interface;
3. In the privacy interface, pull the interface to the bottom, find the diagnosis and dosage button, and click this button to enter the diagnosis and dosage interface, which provides daily log data;
4. Enter the diagnostic dose interface and confirm to select automatic transmission. If it's not automatic, change it to automatic, and check your log data tomorrow, which means that you can only check the battery power and health level tomorrow;
5. If it has been in the automatic transmission state before, click the diagnosis and dose data to enter the data interface;
6. In the data interface, we found a log file of "Log-Summary-Latest Date". If there is no description of the latest date, the data of that day will not be automatically sent, so after selecting Automatic Send, the data will be automatically generated tomorrow, and we will check it later.
7. We click on the log file of "Log-Summary-Latest Date";
8. Then find such a line of data in the pop-up log:
“& ltkey & gtcom . apple . snapshot . battery . max capacity & lt； /key & gt；
& lt integer & gt xxxx & lt/integer > ";
There is a lot of data in the log, so it is recommended to start from the bottom, because this line of data is basically at the bottom of the page.
9.& lt integer & gt xxxx & lt/integer > The middle data is the current maximum capacity of the battery.
