Battery Health: Learn How to Check and Know When to Replace

The battery is a crucial component of your iPhone's functionality. Over time, it naturally degrades, which can affect your device's performance. Therefore, it's essential to know how to check your battery's health and understand when it's time for a replacement. In this article, we provide a clear, step-by-step guide.

Why is checking battery health important?

With continuous use, lithium-ion batteries gradually lose their charge-holding capacity. When the battery's capacity is significantly reduced, your iPhone may experience:

• Slower performance

• Unexpected shutdowns

• Reduced daily battery life

How to check your iPhone's maximum battery capacity

iOS offers a built-in tool to check your battery's health directly from your device's settings.

Follow these steps:

1. Open the Settings app on your iPhone.

2. Tap on Battery.

3. Select Battery Health & Charging.

4. Check the Maximum Capacity.

This percentage represents your battery's current capacity compared to its original state (when new). A new battery should show 100%. Over time, this number naturally decreases.

When is it time to replace the battery?

If the maximum capacity is below 80%, it's a strong indication that the battery is degraded and should be replaced. Your iPhone may also display a message indicating the need for maintenance:

📌 Example: “Your battery health is significantly degraded.”

Additionally, if your device exhibits:

• Slower performance

• Excessive heating

• Difficulty maintaining charge

• Unexpected shutdowns

... these are clear signs that the battery may be nearing the end of its lifespan.

What to do if you need to replace the battery?

If replacement is recommended, seek an Apple Authorized Service Provider or a trusted service center. Replacing the battery with qualified professionals ensures your device's safety and prevents future issues.

Conclusion

Monitoring your iPhone's battery health is a crucial preventive measure to maintain performance and avoid unexpected failures. Regularly check the maximum capacity and stay alert to signs of wear. Replacing the battery at the right time can extend your device's lifespan and provide a better user experience.
