10 Effective Tips to Save Battery on iPhone 15

The iPhone 15 comes with impressive features and performance, but like any smartphone, battery life can be a concern for daily users. Whether you're in the UK, USA, or anywhere else in the world, learning how to save battery on iPhone 15 is essential for getting the most out of your device throughout the day.

Battery drain can be frustrating, especially when you need your phone the most. The good news is that with the right settings and habits, you can significantly improve iPhone battery life and avoid the dreaded low battery warning. This guide will walk you through 10 proven methods to extend your iPhone 15's battery life without sacrificing functionality.

1. Optimize Your Display Settings

Your iPhone's display is one of the biggest battery drains. Here's how to make it more efficient:

Adjust Screen Brightness

  • Go to Settings > Display & Brightness

  • Turn on Auto-Brightness to let your phone adjust brightness based on lighting conditions

  • Manually lower brightness when you don't need it at full power

  • Use Dark Mode to save battery, especially on OLED displays

Reduce Screen Timeout

  • Navigate to Settings > Display & Brightness > Auto-Lock

  • Set it to 30 seconds or 1 minute instead of longer periods

  • This prevents your screen from staying on unnecessarily

2. Manage Background App Refresh

Background App Refresh allows apps to update content even when you're not using them, which drains battery significantly.

How to Control Background App Refresh:

  • Open Settings > General > Background App Refresh

  • Choose Wi-Fi instead of Wi-Fi & Mobile Data

  • Turn off Background App Refresh for apps you don't need updated constantly

  • Keep it on only for essential apps like messaging or email

3. Turn Off Location Services for Unnecessary Apps

Location tracking is a major battery killer. Many apps request location access but don't actually need it.

Steps to Optimize Location Services:

  • Go to Settings > Privacy & Security > Location Services

  • Review each app and change settings to:

    • Never for apps that don't need location

    • While Using App for apps that only need location when active

    • Ask Next Time for occasional use apps

  • Turn off Share My Location if you don't use Find My Friends

4. Disable Push Notifications for Non-Essential Apps

Constant notifications wake up your screen and processor, draining battery power.

Managing Notifications:

  • Open Settings > Notifications

  • Turn off notifications for social media apps, games, and shopping apps

  • Keep notifications on for important apps like:

    • Phone and Messages

    • Calendar and Reminders

    • Work-related apps

  • Choose Manual fetch for email instead of Push

5. Use Low Power Mode Strategically

Low Power Mode is one of the best battery settings for iPhone when you need to extend usage time.

When and How to Use Low Power Mode:

  • Activate it when your battery drops to 20% or lower

  • Turn it on manually through Settings > Battery > Low Power Mode

  • You can also add it to Control Center for quick access

  • Low Power Mode reduces:

    • Background app refresh

    • Automatic downloads

    • Visual effects

    • Email fetch frequency

6. Close Unnecessary Apps and Manage Widgets

While iOS manages apps efficiently, some apps can still drain battery in the background.

App Management Tips:

  • Swipe up from the bottom and swipe up on apps you're not using

  • Remove widgets you don't check regularly from your home screen

  • Go to Settings > Battery to see which apps use the most power

  • Consider deleting apps you rarely use

  • Update apps regularly as newer versions often include battery optimizations

7. Optimize Cellular and Wi-Fi Settings

Network connections can significantly impact battery life, especially in areas with poor signal.

Network Optimization Steps:

  • Turn off Wi-Fi when you're not using it

  • Disable Bluetooth when not needed

  • Go to Settings > Cellular > Cellular Data Options

  • Switch to LTE instead of 5G in areas with weak 5G coverage

  • Turn on Airplane Mode in areas with no signal to prevent constant searching

8. Manage Camera and Photo Settings

The iPhone 15's advanced camera features can drain battery quickly during use.

Camera Battery-Saving Tips:

  • Turn off Live Photos when you don't need them

  • Reduce video recording quality if you don't need 4K

  • Disable HDR for regular photos

  • Avoid using Portrait Mode and Night Mode unless necessary

  • Turn off Location Services for the Camera app if you don't need geotagged photos

9. Control Music and Media Consumption

Audio and video playback can impact battery life, especially with certain settings enabled.

Media Optimization:

  • Use wired headphones instead of Bluetooth when possible

  • Lower the volume to reduce power consumption

  • Download music for offline listening instead of streaming

  • Close video apps completely when finished watching

  • Turn off Raise to Wake if you don't need it



10. Regular Battery Health Maintenance

Maintaining good battery health practices ensures long-term battery performance.

Battery Health Best Practices:

  • Check your battery health in Settings > Battery > Battery Health & Charging

  • Avoid letting your battery drop to 0% regularly

  • Don't leave your phone charging overnight every night

  • Keep your iPhone at room temperature when possible

  • Remove thick cases while charging to prevent overheating

  • Update to the latest iOS version for battery optimizations

Additional Quick Tips for Better Battery Life

  • Restart your iPhone once a week to clear temporary files

  • Check for iOS updates regularly in Settings > General > Software Update

  • Use original or certified chargers to maintain battery health

  • Enable Optimized Battery Charging in battery settings
