2. Open the Settings app and head to Privacy & Security > Analytics & Improvements.

4. Tap the latest Analytics file available. (The file's name will be something like Analytics-2024-02-28-080003.ips.ca.synced.)

5. Tap the Share button and select Battery Health Checker.  

6. Your current maximum battery capacity will be displayed at the top.

*Attention: Step 3, Share iPhone Analytics need to be enabled and wait to next day, then the Analytics file (start with Analytics-Year-Month-Day) will appear.
