How to Extend Your iPhone Battery Life: Proven Tips for 2025

Nothing’s worse than your iPhone running out of power halfway through the day. Whether you’re on the latest iPhone 15 or using an older model, battery life can make or break your daily routine. Thankfully, Apple has built-in tools and settings that help you maximize iPhone battery life—and with a few smart habits, you can stretch each charge much further.

Here are the most effective strategies to keep your iPhone powered longer in 2025.

1. Turn On Low Power Mode

Low Power Mode is the simplest way to save energy. It reduces background activity, mail fetch, automatic downloads, and some visual effects. You can enable it quickly from Settings → Battery → Low Power Mode, or add it to Control Center for one-tap access.

2. Adjust Screen Brightness and Auto-Lock

The display is one of the biggest battery drainers. Lowering your brightness and enabling Auto-Brightness helps your iPhone adapt to lighting conditions automatically. Also, set your Auto-Lock to 30 seconds or 1 minute so your screen doesn’t stay on longer than needed.

3. Use Dark Mode

If your iPhone has an OLED display (iPhone X and later), Dark Mode saves energy by turning off pixels in darker areas of the screen. Not only does it look sleek, but it also improves battery performance over time.

4. Manage Background App Refresh

Go to Settings → General → Background App Refresh and turn it off for apps that don’t need constant updates. Social media apps are usually the biggest culprits here, and limiting them will instantly give you more standby time.

5. Update to the Latest iOS

Apple frequently optimizes battery performance through iOS updates. Make sure your iPhone is running the latest software under Settings → General → Software Update.

6. Limit Location Services

GPS can drain your battery quickly. Head to Settings → Privacy & Security → Location Services and change unnecessary apps to “While Using the App” or “Never.” This ensures only essential apps like Maps use your location in the background.

7. Avoid Extreme Temperatures

Apple recommends keeping your iPhone between 0°–35°C (32°–95°F). Cold or hot environments can cause your battery to drain faster or even degrade long-term performance.

8. Monitor Battery Health

In Settings → Battery → Battery Health & Charging, you can check your Maximum Capacity and enable Optimized Battery Charging. This feature reduces wear on your battery by learning your daily charging habits and slowing down charging past 80% until you need it.

9. Use Wi-Fi Over Cellular Data

Whenever possible, connect to Wi-Fi instead of cellular data. Cellular connections use more power, especially in areas with weak signals.

10. Close Power-Hungry Apps and Widgets

Widgets like weather updates and apps running AR or 3D features can drain extra energy. Keep your Home Screen clean and limit background activity for apps you rarely use.
