The Peak Performance Capability section primarily focuses on how your battery affects the overall performance of your iPhone. If your Peak Performance Capability is marked as "Normal Performance," it means your battery is healthy and can support peak performance levels.
However, if your iPhone indicates "Battery Needs Servicing" or "Performance Management," it suggests that your battery’s health is significantly degraded, and it might be causing performance issues.
- "Battery Needs Servicing": This message often appears if your battery’s health has fallen below a certain threshold. Apple’s performance management features have likely been engaged to prevent unexpected shutdowns. However, in these circumstances, replacing the battery is recommended for optimal performance.
- "Performance Management": This message indicates that Apple’s performance management features are actively working to manage your iPhone’s performance. It might be a precautionary measure against unexpected shutdowns. While this feature aims to ensure smooth operation, it can potentially result in slower app launches, reduced processing speeds, and other noticeable performance reductions. If you’re experiencing such performance degradations, replacing your battery might be a solution.
