How to check battery health on iphone?

By HotBotUpdated: July 17, 2024

The battery health of your iPhone is crucial for its performance and longevity. Over time, batteries degrade, leading to shorter battery life and potential performance issues. This comprehensive guide will walk you through the various methods to check the battery health of your iPhone, ensuring you stay informed and proactive about maintaining your device's efficiency.

1. Using the Built-in Battery Health Feature

Apple provides a built-in feature that allows users to monitor their iPhone's battery health. This feature is available on iPhones running iOS 11.3 or later. Follow these steps to access it:

1. Open the Settings app on your iPhone.
2. Scroll down and tap on Battery.
3. Tap on Battery Health & Charging.
4. Here, you will see the Maximum Capacity percentage and Peak Performance Capability.

The Maximum Capacity percentage indicates the battery's capacity relative to when it was new. A lower percentage means the battery holds less charge. Peak Performance Capability provides information on whether the battery can handle peak performance requirements.

2. Understanding the Battery Health Metrics

Maximum Capacity

The Maximum Capacity metric shows the battery's charge capacity compared to its original state. A new battery should have a capacity of 100%. Over time, this number will decrease as the battery undergoes charge cycles.

Peak Performance Capability

Peak Performance Capability indicates if your battery can support the power demands of your iPhone under heavy load. If your battery health degrades significantly, iOS may apply performance management to prevent unexpected shutdowns. In such a case, you might see a message indicating that performance management has been applied.

3. Checking Battery Health Using Third-Party Apps

Several third-party apps can provide more detailed insights into your iPhone's battery health. Some popular options include:

• CoconutBattery (for Mac users): Connect your iPhone to your Mac and launch CoconutBattery. It provides detailed information about your iPhone's battery, including cycle count, temperature, and more.
• Battery Life: Available on the App Store, this app offers detailed battery health statistics, including capacity, wear level, and charge cycles.

These apps can provide additional data that might not be available through the built-in Battery Health feature, offering a more comprehensive understanding of your battery's condition.

4. Recognizing Signs of Battery Degradation

Apart from numerical metrics, certain signs can indicate battery degradation:

• Decreased Battery Life: If your iPhone's battery drains faster than usual, it could be a sign of degradation.
• Unexpected Shutdowns: If your iPhone shuts down unexpectedly, it may indicate that the battery can't support peak power demands.
• Slow Performance: iOS may apply performance management to prevent shutdowns, leading to slower overall performance.

5. Maintaining and Improving Battery Health

To prolong the life of your iPhone's battery, consider the following tips:

Avoid Extreme Temperatures

Keep your iPhone within the recommended temperature range (0°C to 35°C). Exposing your device to extreme temperatures can accelerate battery degradation.

Optimize Charging Habits

Use optimized charging, a feature introduced in iOS 13, which learns your charging routine and reduces the time your iPhone spends fully charged, thereby reducing battery wear. Enable it by:

1. Going to Settings.
2. Tap on Battery.
3. Select Battery Health & Charging.
4. Toggle on Optimized Battery Charging.

Avoid Full Discharge

Try to keep your battery level between 20% and 80%. Completely discharging your battery to 0% can strain it, as can keeping it fully charged for extended periods.

6. When to Replace Your iPhone Battery

Eventually, you may need to replace your iPhone's battery. Consider replacement if:

• The Maximum Capacity falls below 80%.
• You experience frequent unexpected shutdowns.
• Performance management is persistently applied.

Apple offers battery replacement services, and you can check the cost and process on their official website. Alternatively, authorized service providers can also perform battery replacements.

7. Using Apple Support for Battery Health Concerns

If you're unsure about your battery health or experiencing issues, you can always contact Apple Support. They can perform a diagnostic test to determine your battery's condition and provide recommendations.

To contact Apple Support:

1. Open the Support app on your iPhone.
2. Select Battery & Charging.
3. Follow the prompts to chat with or call an Apple Support representative.

Alternatively, you can visit an Apple Store or an authorized service provider for in-person assistance.

8. Battery Health Myths and Facts

Several myths about iPhone battery health circulate online. Here are some clarified:

Myth: Closing Apps Saves Battery

Fact: Continuously closing apps can actually consume more battery, as reopening them uses more power. iOS is designed to manage background apps efficiently.

Myth: Using a Non-Apple Charger Damages the Battery

Fact: While it's best to use certified chargers, most third-party chargers that meet safety standards will not harm your battery. However, avoid cheap, uncertified chargers.

Myth: Turning off Wi-Fi and Bluetooth Always Saves Battery

Fact: While turning off these features can save battery in some cases, iOS is optimized to manage these connections efficiently, and turning them off may not significantly impact battery life.

9. Advanced Battery Health Monitoring

For users who want to delve deeper into battery health, advanced tools and diagnostics are available. These tools require more technical knowledge but can provide extensive insights into battery performance and degradation. Some advanced methods include:

Using Console Logs

Connect your iPhone to a Mac and use the Console app to view detailed logs about battery performance. This method requires familiarity with reading and interpreting logs.

Developer Tools

iOS developers have access to tools and diagnostic features that can provide comprehensive battery health data. These tools are typically available through Apple's development platforms and require a developer account.

Understanding and monitoring your iPhone's battery health is essential for maintaining optimal performance and longevity. With built-in features, third-party apps, and proper maintenance, you can ensure your device remains reliable and efficient. Whether you're a casual user or a tech enthusiast, staying informed about battery health empowers you to make the best decisions for your iPhone's care.
