Your iPhone’s battery is its lifeline, powering everything from calls and messages to apps and high-resolution photos. Over time, battery performance naturally declines, affecting your phone’s speed, battery life, and overall usability. Understanding battery health and knowing your repair options can help you get the most out of your device.
What Is iPhone Battery Health?
Apple’s Battery Health feature shows the Maximum Capacity and Peak Performance Capability of your iPhone battery.
Why It Matters
- Maximum Capacity reflects the battery’s ability to hold charge compared to when it was new.
- Peak Performance Capability shows whether the battery can deliver enough power for demanding tasks without unexpected shutdowns.
Signs Your iPhone Battery Needs Attention
When your battery health drops below 80%, you may notice:
Common Symptoms
- Rapid battery drain even with minimal use
- iPhone shutting down unexpectedly
- Slow performance during high-usage apps
- Device heating up frequently
Causes of Battery Health Decline
Battery wear is natural, but certain factors accelerate it.
Key Causes
- Frequent full discharges
- Prolonged exposure to heat
- Using non-certified charging cables

Pro Tip
Keep your iPhone between 20%–80% charge whenever possible to extend its battery life.
