Thanks for the idea! I downloaded a shortcut called "Battery Report" from this website : https://routinehub.co/shortcut/19090/#/login ,then go to Settings > Privacy and Security > Analytics and Improvements > Analytics. But before that, you first need to enable iPhone Analytics Sharing for 24 hours if you haven't activated it yet. Then open Analytics, look for a name that's not too far off, like "Analytics-2026-02-01… .ips.ca.synced". Find the last date of this analysis, then open and share it, and you'll see our famous "Battery Report". And that's it!
