How to save iPhone 15 battery health and fix drain issues?

Battery health issues are a common complaint among iPhone users, especially when a new device seems to drain power too quickly. With the iPhone 15 series (including the iPhone 15, Plus, Pro, and Pro Max) being packed with powerful features, it's important to ensure you're taking the right steps to protect your battery health and prevent unnecessary battery drain.

Here are some quick tips to help you extend your iPhone 15 battery life and keep it in top condition:


1. Check Your Battery Health (Max Capacity)

Before doing anything else, you should make sure that your iPhone 15’s battery is at its full potential. New iPhones are designed to start with 100% battery health, but it’s always a good idea to check.

To check your battery health:

  • Go to Settings
  • Scroll down and tap Battery
  • Tap Battery Health & Charging
  • Here you’ll see your Maximum Capacity. If it’s at 100%, you’re good to go. If it’s lower than that, your battery’s health might be declining.

2. Activate the Battery Percentage Meter

Seeing exactly how much battery you have left can help you manage your usage better, so it's a good idea to have the battery percentage indicator visible at all times.

To enable battery percentage:

  • Go to Settings
  • Scroll down and tap Battery
  • Toggle on the Battery Percentage option.

3. Optimize Charging with ‘Battery Health & Charging’

iPhones come with a smart charging feature that helps prolong battery life by learning your charging habits and optimizing the charging process.

Here’s how Charging Optimization works:

  • Go to Settings
  • Scroll down and tap Battery
  • Tap Battery Health & Charging
  • Tap Optimized Battery Charging

By default, this feature is turned on to Optimize Battery Charging, which reduces wear by limiting your iPhone’s charging to 80% until it knows you’ll need it fully charged (like in the morning). This helps prevent your battery from staying at 100% for too long, which can wear it out over time.

Note: If you turn off this feature, the charging speed will increase, but so will the rate of battery degradation. If you want to maximize battery health, it’s best to leave this feature on.

Alternatively, if you want to limit charging to 80% consistently for even better battery longevity, you can set that option.


4. Activate Power Saving Mode Automatically

You don’t have to manually turn on Low Power Mode every time your battery dips low. iPhone 15 allows you to create an automation that can turn it on automatically when your battery reaches a certain level.

To activate automatic Low Power Mode:

  • Open the Shortcuts app
  • Go to the Automation tab
  • Tap Create Personal Automation
  • Scroll down and select Battery Level
  • Set the slider to the percentage at which you want Low Power Mode to activate (e.g., 20% or 30%)
  • Tap Next
  • Tap Add Action, then search for Low Power Mode
  • Turn on Low Power Mode
  • You can also add a condition to turn it off once your battery reaches a higher percentage, like 80%.

This way, you can save battery power automatically without needing to worry about manually adjusting settings.

5. Turn Off Location Services for Certain Apps

Location services can drain your battery, especially if multiple apps are constantly tracking your whereabouts. If you’re not using an app that requires your location, it’s a good idea to turn it off for those apps.

To manage Location Services:

  • Go to Settings
  • Tap Privacy & Security
  • Tap Location Services
  • Review the list of apps, and disable location access for those you don't need it for.

By only allowing location access for the apps that truly need it, you can save battery and reduce unnecessary power drain.


6. Avoid Extreme Temperatures

iPhones don’t perform well in extreme temperatures, and both cold and hot weather can lead to faster battery drain and damage over time. Try to keep your device in a temperature range of 32°F to 95°F (0°C to 35°C). Avoid leaving your iPhone in direct sunlight or in a hot car, as excessive heat can cause the battery to degrade more quickly.


7. Manage Background App Refresh and Notifications

Background App Refresh allows apps to update content even when you’re not using them, which can consume battery power. Similarly, constant notifications can wake up your phone and use additional resources.

To manage these settings:

  • Go to Settings
  • Tap General
  • Select Background App Refresh, and disable it for apps you don’t need to refresh constantly
  • Go to Settings
  • Tap Notifications and turn off notifications for apps that don’t require your immediate attention.

Conclusion

By following these simple tips, you can save your iPhone 15’s battery health, extend its lifespan, and fix any battery drain issues. It’s all about managing your settings to prevent excessive battery consumption, and with a little care, your iPhone 15 will continue performing at its best for a long time.

Remember: Smart charging practices, location settings, and power-saving modes can make a huge difference in maintaining battery health. Stay on top of your device’s needs, and enjoy all the amazing features your iPhone 15 has to offer without constantly worrying about the battery!
