How to Fix iPhone 15 Battery Draining Fast

Is your iPhone 15 battery draining faster than usual? If so, you’re not alone! Many users have experienced this issue, which can be frustrating. But don’t worry, there are steps you can take to fix it and extend your battery life.

Common Causes of Battery Drain

Background App Refresh: One common reason for the iPhone 15 battery draining fast is the background app refresh feature. This feature allows apps to update their content in the background, which can consume a significant amount of battery power. To optimize battery life, you can disable this feature for specific apps or altogether in the settings.

Location Services: Location services that constantly track your device’s location can also contribute to battery drain. Some apps may use location services even when they’re not actively in use, leading to unnecessary power consumption. You can manage and customize location services for individual apps to save battery life.

Brightness: Keeping the brightness level high on your iPhone 15 can quickly drain the battery. Lowering the brightness or enabling auto-brightness can help conserve battery power. Auto-brightness adjusts your screen brightness based on ambient light conditions, providing an optimal balance between visibility and battery usage.

Auto-Lock: The longer your iPhone screen remains on, the more battery it consumes. Setting a shorter auto-lock time can significantly reduce battery drain. This feature automatically locks your device’s screen when it’s inactive for a specified period.

Optimizing Battery Life

Saving battery life on your iPhone 15 can be achieved by utilizing the Low Power Mode feature. When enabled, this feature reduces power consumption by disabling unnecessary background processes and reducing screen brightness. To enable Low Power Mode, go to Settings > Battery > Low Power Mode. It is recommended to use this feature when your battery is running low or during extended periods without access to charging.

Managing Always-On Display and Temperatures

The Always-On Display feature on the iPhone 15 can drain battery life significantly. Consider disabling this feature if you want to conserve battery power. To do this, go to Settings > Display & Brightness > Always-On Display. Additionally, extreme temperatures can also affect battery performance. Avoid exposing your device to excessive heat or cold, as it can cause the battery to drain faster. If you notice your iPhone heating up, try removing any protective cases and allowing it to cool down.

By implementing these tips and making small adjustments to your iPhone 15 settings, you can effectively extend your battery life and improve overall device performance. Remember to regularly monitor your battery usage and consider carrying a portable charger for emergencies.

App Usage and Updates

Checking and managing app usage

To address the issue of the iPhone 15 battery draining fast, one should start by checking and managing app usage. Some apps may run continuously in the background, consuming a significant amount of battery power. Users can check app battery usage by going to Settings > Battery. Here, they can identify which apps are consuming the most battery and take necessary actions such as closing unnecessary apps or limiting their background activity.

Updating problematic apps

Outdated or faulty apps can also contribute to battery drain. Users should regularly update their apps to ensure they have the latest bug fixes and optimizations. To update apps, go to the App Store and tap on the Updates tab. From there, users can update individual apps or choose to update all apps at once.

By keeping apps up to date and managing their usage, iPhone 15 users can mitigate battery drain issues and prolong their device’s battery life. Additionally, it is recommended to enable low power mode, reduce screen brightness, and disable unnecessary features or notifications to further conserve battery power. By implementing these strategies, users can enjoy longer battery life and a better overall experience with their iPhone 15.

Preventing Overheating Issues

Limiting the usage of problematic apps

To prevent excessive battery drain on your iPhone 15, it’s important to identify and limit the usage of problematic apps. Some apps may run in the background and consume more power than others. Check your battery usage settings to identify which apps are draining your battery the most. Consider closing unused apps or disabling background refresh for apps that are not essential.

Updating and managing app updates

Keeping your apps updated can also help in preventing battery-draining issues. Developers often release updates that address performance and battery optimization. Make sure to regularly check for and install app updates from the App Store. It is also recommended to manage automatic app updates and disable them if necessary, as automatic updates can drain your battery faster.

Additionally, consider optimizing your device’s settings to reduce battery usage. Lowering the screen brightness, enabling low power mode, and disabling unnecessary push notifications can contribute to better battery life on your iPhone 15.


Using these strategies and adopting good battery-saving habits will help you maximize the battery life of your iPhone 15. If, however, the battery of your iPhone is still low, contact Apple support or change a quality battery like REPART.
