1. What is iPhone battery health?

Battery health refers to your battery’s ability to hold a charge compared to when it was new. Apple introduced the Battery Health feature to help users better understand the long-term condition of their iPhone battery. It gives you insight into how your device is performing and whether your battery may be limiting performance.

Learning how to check battery health on iPhone gives you a clearer picture of your device’s reliability and when it might be time to replace the battery.

2. How to check battery health on iPhone (built-in method)

If your iPhone doesn’t last as long on a single charge, it might be more than just heavy usage, it could be a sign of aging battery cells. The good news is, Apple has made it simple to stay informed. Learning how to check battery health on iPhone helps you understand whether your battery is still in good shape or starting to decline, so you can plan ahead before it affects performance.

To check battery health on iPhone, follow these steps:

Open the Settings app on your iPhone. Scroll down and tap Battery.

Tap Battery Health & Charging.

Look at the section labeled Maximum Capacity. This shows the percentage of battery capacity your iPhone has retained compared to when it was new.

A maximum capacity above 90% indicates excellent battery condition. Between 80% and 89% is still serviceable, though signs of aging may appear. If the capacity falls below 80%, your iPhone might experience reduced performance, and a battery replacement is usually recommended.

Check Battery Life Stats: Apple provides built-in tools similar to a battery report on Windows. In the Battery section of your settings, you’ll find visual graphs that show recent charging activity and usage. The Last Charged indicator displays when your iPhone was last plugged in and how much charge it had when unplugged.

3. Signs your iPhone battery may need replacing

Even without checking battery stats, your iPhone may show physical signs of battery aging. These can affect daily usability and even the safety of your device.

Look out for these warning signs:

  • The battery drains noticeably faster than before
  • Your phone randomly shuts down even with charge remaining
  • Apps and tasks feel slower or laggy
  • The Battery Health section reports capacity below 80%
  • You see a message saying “Battery health significantly degraded”

4. Tips to extend and protect battery health

Good battery habits can help delay the natural aging process and reduce wear over time. Small daily choices make a big difference.

To keep your iPhone battery healthier for longer:

  • Avoid exposing your phone to hot or freezing environments
  • Enable Optimized Battery Charging in the Battery Health & Charging settings
  • Try to keep your battery between 20% and 80% most of the time
  • Remove thick or insulated cases if your phone gets warm during charging
