About this part
The Battery, pSIM (Apple part number 661-56121) is a genuine Apple part that fits the iPhone 17 Pro (2025). The battery powers the iPhone away from the wall and also steadies power delivery under heavy load, so a worn cell affects performance too.
Before you order, check the model name on your iPhone (Settings, General, About) and confirm it is listed in the compatibility table above.
Signs the battery needs replacing
- "Service Recommended" in the battery status menu
- Short runtime, or the iPhone shuts off at 20 to 40 percent
- A swollen battery lifting the trackpad or bottom case
- Slowdowns that disappear when the charger is plugged in
