How to Check iPhone Battery Health: Steps & Tips (2025)
Checking your iPhone’s battery health is essential to preserve battery life and detect potential issues early. Apple’s built-in tools make it simple, and 2025 updates bring new insights to help users optimize their device performance.
Why Battery Health Matters
Over time, lithium-ion batteries degrade, reducing capacity and charging efficiency. Monitoring battery health helps identify wear, optimize charging habits, and prevent sudden shutdowns. Apple tracks health using a degradation percentage, which reflects how much the battery’s maximum capacity has dropped since new.
How to Access Battery Health via iOS Settings
- Open Settings on your iPhone.
- Tap Battery, then select Battery Health (available on devices running iOS 17+).
- Here, you’ll see two key metrics: Maximum Capacity and Peak Performance Capability. Maximum Capacity shows the current health percentage—ideal for benchmarking. Peak Performance Capability indicates how well the battery supports fast charging over time.
Understanding the Battery Health Report
The report displays a graph comparing current capacity to the original, helping you visualize degradation. A healthy battery typically stays above 80%. If capacity drops below 80%, consider replacing the battery—especially if you notice slower charging or unexpected restarts. Apple’s 2025 data shows that frequent fast charging and high usage can accelerate wear, making regular checks crucial.
Tips to Maintain Optimal Battery Health
- Avoid exposing your device to temperatures above 35°C (95°F) or below 0°C (32°F).
- Charge between 20% and 80% for daily use to reduce long-term stress.
- Enable Low Power Mode when battery drops below 20% to extend usage.
- Update iOS regularly—Apple improves battery management in newer versions.
- Reset All Settings occasionally to recalibrate battery metrics.
The Role of Third-Party Tools and Careful Use
While iOS offers reliable data, third-party apps like AccuBattery or Battery Doctor provide deeper insights, though always from trusted sources. Avoid unverified apps that claim extreme health percentages—Apple’s data remains the gold standard. Pair tool use with consistent healthy habits for best results.
Conclusion
Checking your iPhone battery health is a simple yet powerful way to protect your device’s lifespan. By using Apple’s built-in tools and following best practices, you can maintain peak performance and avoid unexpected battery issues. Start today: open Settings, explore Battery Health, and take control of your iPhone’s battery story in 2025 and beyond. Don’t wait—check it now and keep your device reliable every day.
