How to fix battery draining quickly on iPhone 15 Pro Max?

The iPhone 15 Pro Max is a marvel of modern technology, boasting a host of impressive features and capabilities. However, like any electronic device, it's not without its quirks. One common issue that users often encounter is the battery draining quickly. If you're one of those users, don't fret! This comprehensive guide will walk you through a series of steps to help you troubleshoot and resolve this issue.

Understanding the Issue

Before we delve into the solutions, it's crucial to understand why this problem occurs in the first place. The iPhone 15 Pro Max, like its predecessors, is designed to provide a seamless user experience. However, certain factors can cause the battery to drain faster than usual.

These factors can range from software issues, such as bugs in the operating system, to hardware issues like a faulty battery. Additionally, certain user habits, like leaving apps running in the background or using high-brightness settings, can also contribute to rapid battery drain.

Checking Battery Health

Apple provides a handy tool within the iPhone settings that allows you to check the health of your battery. This tool can give you a good idea of whether your battery is functioning as it should.

To access this tool, navigate to Settings > Battery > Battery Health. Here, you'll see a percentage that represents your battery's maximum capacity. If this number is significantly lower than 100%, it might be time to consider a battery replacement.

However, if your battery health is good, the issue likely lies elsewhere. In this case, you'll need to explore other potential solutions.

Optimizing Settings

Adjusting Screen Brightness

The iPhone 15 Pro Max features a stunning Super Retina XDR display, which, while beautiful, can be a significant drain on your battery. One simple way to conserve battery life is to lower your screen brightness.

To do this, go to Settings > Display & Brightness and adjust the slider to a lower setting. You can also enable auto-brightness, which will automatically adjust your screen brightness based on your environment.

Turning Off Background App Refresh

Another common culprit of battery drain is apps running in the background. While this feature can be useful for keeping your apps up to date, it can also consume a lot of power.

You can disable this feature by going to Settings > General > Background App Refresh and toggling off the switch. You can also choose to disable this feature for specific apps if you prefer.

Updating iOS

Sometimes, the issue can be as simple as needing to update your operating system. Apple regularly releases updates to fix bugs and improve performance, which can often resolve battery drain issues.

To check for updates, go to Settings > General > Software Update. If an update is available, tap "Download and Install".

Resetting Settings

If none of the above solutions work, you might need to consider resetting your iPhone settings. This action won't delete any of your data, but it will reset all your settings to their default state.

To do this, go to Settings > General > Reset > Reset All Settings. You'll need to enter your passcode, and then your iPhone will restart with default settings.

After the reset, monitor your battery usage to see if the issue has been resolved. If not, you might need to consult with an Apple technician for further assistance.


While it can be frustrating to deal with a quickly draining battery, there are several steps you can take to troubleshoot and resolve the issue. By understanding the potential causes, checking your battery health, optimizing your settings, and even resetting your iPhone if necessary, you can help ensure that your iPhone 15 Pro Max's battery lasts as long as possible.

Remember, if all else fails, don't hesitate to reach out to Apple Support. They're there to help you make the most of your iPhone experience.
