Step one:
First, we need to click "Settings" on the iPhone, and then select the "General" option.
Step two:
After entering, click the "About this machine" page, then slide down the menu to find "Diagnosis and Dosage", and click Enter.
Step 3:
After that, we will select "Auto Send" in the menu that appears again, and then wait for one day to enter again and click "Diagnosis and Dose" before selecting "Diagnosis and Dose Data". If we have checked "Auto Send", we can click "Diagnosis and Dose Data" directly.
Step 4:
Click "Diagnosis and Dose Data", find the file starting with "log-aggregated", and then select the latest log file. In this log file, the number after viewing "maxCapacity" is the "maximum battery capacity" we are looking for. This function can also check whether there is something wrong with the battery of the mobile phone. After all, if the capacity is small, the problem of fast power consumption means that the battery of the mobile phone is almost dead. On the contrary, we need to pay attention to how to save electricity when using mobile phones.
That's how to check the battery health of Apple's mobile phone. I believe everyone will soon learn how to set it up.
