Step 1. Enter Settings.

Step 2. Go to Apps > App Updates.

Step 3. Enter App Store and toggle off App Updates to prevent apps from downloading automatically.

Method 5. Disable Background Refresh

Background App Refresh allows apps to update content even when they're not actively in use. While convenient, it's a significant drain on your battery. Disabling this feature ensures apps only consume power when opened, enhancing battery life without compromising functionality.

Step 1. Access Settings.

Step 2. Touch on General and tap Background App Refresh.

Step 3. Tap Background App Refresh and select Off, or you can disable the refresh for individual apps on this page.

🎯What You Should Enable

As we mentioned before, disabling certain features can help conserve battery, while enabling specific settings can also optimize your iPhone's performance and power consumption. Here's what you should turn on to fix the battery drain fast issue.

Method 6. Enable the Low Power Mode

Step 1. Tap Settings on your iPhone.

Step 2. Pick Battery under the Settings page.

Step 3. Then switch on the Low Power Mode button.

Method 7. Enable the Airplane Mode

Another mode you can enable to save your iPhone battery is the Airplane Mode. It disables wireless connections, including cellular data, Wi-Fi, and Bluetooth. This feature can prevent the battery from draining fast when your iPhone is searching for a connection in some areas with poor signal.

Option 1. Wake up the Control Center and tap on the airplane icon to enable the airplane mode.

Option 2. You can also go to Settings and toggle off the Airplane Mode.

Method 8. Enable the Dark Mode

Dark Mode reduces battery usage on OLED and AMOLED screens by displaying darker colors. By minimizing the number of bright pixels, this feature can significantly conserve energy. It also provides a visually soothing interface. Here's how to enable it.

Step 1. Run Settings.

Step 2. Tap on Display & Brightness.

Step 3. Continue to press the Dark icon to enable the dark mode.

Method 9. Enable the Auto-Brightness

You can adjust your screen's brightness based on ambient lighting conditions by Auto-Brightness. This feature optimizes power consumption by reducing brightness in low-light environments and increasing it only when necessary. Keeping it enabled ensures efficient energy use without manual adjustments.

Step 1. Run Settings.

Step 2. Touch on Accessibility, then hit on the Display & Text Size option.

Step 3. Swipe up to find Auto-Brightness and then enable it.

Method 10. Fix iOS System Problems

Sometimes, unexpected battery drain is caused by underlying system glitches that are difficult to pinpoint. Using the MagFone iOS System Recovery can help resolve these issues without data loss. This tool repairs system errors that may be causing the battery to deplete faster than usual.

Part 3. How to Stop Battery Draining Fast iPhone

If your iPhone battery continues to drain quickly despite optimizing settings, additional steps may be necessary. Limiting certain system processes and usage habits can have a significant impact. By managing software and hardware aspects carefully, you can extend your iPhone's battery life.

Method 1. Downgrade iOS System

Sometimes, new iOS updates come with bugs or more features that negatively impact battery performance. Many users have reported faster battery drain after updating to the latest iOS version. Downgrading to a previous version can often resolve these issues. If you're not satisfied with your iPhone's battery performance, you can try downgrading your iOS version using MagFone iOS System Recovery or the methods outlined in the following post.

This practice allows your device to function more efficiently, helps conserve energy, and ensures that battery life is preserved for essential tasks throughout the day.

Method 5. Manage Wi-Fi and Bluetooth

Keeping Wi-Fi and Bluetooth active when not in use can drain your battery by continuously searching for available connections. This ongoing search consumes power unnecessarily and leads to faster battery depletion.

Method 6. Replace the Battery

If your iPhone's battery drains quickly despite trying all the usual fixes, it may be time for a replacement. As batteries age, they lose their ability to hold a charge, which can impact performance. Replacing your battery with a genuine Apple part can restore your iPhone's efficiency, improve performance, and extend its lifespan.
