Steps To Fix Battery Draining Issue Of iPhone 15 

The first and most critical step is to pick out the main causes of the battery drain. Is it an uncontrollable app, a glitch, or a more complex device issue? Let’s discover.

Check For The Battery Usage

One of the primary steps in understanding the reason for your battery drain is checking the battery utilization data. Navigate to your “iPhone’s Settings” and locate the battery option. 

This step offers you detailed information on apps consuming the most power. Identify any unusual suspects disturbing your battery’s life. By recognizing these culprits, you could take suitable action to mitigate the drain.

Update iOS for a Power Boost

Updating your iOS to the latest model can amend underlying troubles that contribute to battery drainage. Ensure your tool is working with the latest software system updates by navigating to Settings > General > Software Update. This simple step can make a huge difference in your battery’s overall performance.

Say Goodbye to Background Apps

Background apps can slowly drain your battery. Double-click on the “Home button” or swipe up from the bottom of the display screen and swipe up at the apps to shut them. By shutting down these unnecessary background apps, you can preserve valuable battery power.

Reduce Screen Brightness

Lowering your screen brightness is a powerful way to save your battery. Swipe down from the top-right corner of your display and adjust the brightness slider to a comfortable but power-saving level. This small adjustment can notably increase your device’s battery life.

Activate Low Power Mode

When your battery is decreasing unexpectedly, activating “Low Power Mode” can be a savior. This feature limits background activities, reduces visual effects, and optimizes your device for maximum power efficiency. 

You can enable “Low Power Mode” by going to Settings > Battery. Turn to this mode to prolong your iPhone’s battery life.

Disable Background App Refresh

Certain apps refresh themselves in the background, contributing to useless battery drainage. Disable this selection for apps that do not require constant refreshing. Head to Settings > General > Background App Refresh and switch off the apps that don’t need to refresh in the background. 

Location Services Control

Location services can be an enormous drain on your iPhone’s battery. Limit access to the location services for apps that don’t actually require it. Go to Settings > Privacy > Location Services to regulate those settings and preserve your precious battery life.

Check for App Updates

Outdated apps can often be the source of battery drain troubles. Go to the “App Store” and take a look at pending updates. Install any available updates, as they often consist of computer virus fixes and optimizations that can resolve battery-related problems.

Reset All Settings

A reset can be the solution to slow battery drain issues. Go to Settings > General > Reset > Reset All Settings. This step will not erase your data, but it’ll reset settings like Wi-Fi passwords and display settings. This reset will help eliminate settings-related glitches causing the battery drain.
