The battery fitness workaround: How Scriptable reveals the actual battery health of your (old) iPhone. ☑︎ With my script and instructions, you can read the battery data directly on your iPhone without external devices such as a Mac.

Instructions and article (in German): anb030.de

Briefly explained:

ⓘ
Please first open the "Analytics" file from the Settings app. There, select the options in order: Privacy & Security → Analytics & Improvements *¹ → Analytics Data. Then open the desired "Analytics" file, share it via the Share Sheet (Share menu) and save it to Apple’s "Files" app.

*¹ Note: Please enable the switch Share iPhone & Watch Analytics at least 24 hours in advance so that the "Analytics..." file can be generated for extraction.

ⓘ
Locate the file in the “Files” app and change its file extension (suffix) *² by long-pressing → context menu option “Rename” from “.synced” to “.txt”. Then share it again via the Share Sheet (Share menu) with the Scriptable script *³ “BatteryFitness++”. The Scriptable app should then open automatically and display all relevant battery data.

*² Note: In the "Files" app you must enable a small setting: Tap the three "•••" dots at the top right → Scroll down to "View Options" → Scroll further down to "Show All File Extensions" and enable the switch.

*³ Note: In the "Scriptable" app you must enable a small setting: Open the created script card named “BatteryFitness++” again via the three dots "•••" → Tap the menu icon “≒” above the keyboard → Then tap the menu item “Share Sheet Inputs” → Check all boxes to enable proper sharing for the Share menu.
