How to use it is simple: extract the system analysis file, and then draw a conclusion through this shortcut instruction.
First, we need to extract the analysis file. Go to System Settings-Privacy-Analysis and Improvement-Analyze Data, then find the file starting with log-agg, select one of the latest dates, click the Share button in the upper right corner, and save it in the file App that comes with the system (if there is no such file, you need to turn on the switch above and try again the next day).
Need to know:
The next step is the operation in the shortcut command. Click to run the "Battery Life" shortcut command, then select "Start Analysis", and select the file at the beginning of the log-agg just saved to get the desired result. Continue to click "Historical Data" to view the results of previous queries.
Whether the battery life is accurate or not is a quick instruction to analyze the single data of the system file. If the results of querying a single data are mostly inaccurate, sometimes the battery capacity is only over 300, and sometimes the query life is even longer than 100%.
In fact, the real life of the battery, the iOS system is based on a series of summarized file data, so everyone just needs to pay attention to the data in the battery health. In a word, this quick instruction has certain reference value, but it doesn't need to be taken too seriously.
