The iPhone is one of the most powerful and refined smartphones available today—but even with Apple’s advanced battery technology, many users struggle to make it through a full day without a charge. Whether you’re using the latest model or an older generation, poor battery performance can stem from a range of overlooked settings and habits.

In this guide, we’ll share 10 genius tips that can dramatically improve your iPhone’s battery life without sacrificing performance. These practical tips go beyond generic advice, offering strategic insights based on the latest iOS features and real-world use cases.

1. Enable Low Power Mode Early, Not Late

Many iPhone users only switch on Low Power Mode when their battery hits 20%, but enabling it proactively—especially during travel or long meetings—can preserve battery life more effectively. This setting reduces background activity, disables visual effects, and pauses Mail fetch.

You can even automate it using Shortcuts in iOS. Simply set a trigger to enable Low Power Mode at a specific battery level or location.

2. Tame Background App Refresh

Background App Refresh allows apps to update content in the background, draining both battery and data. Navigate to:

Settings > General > Background App Refresh

Choose Off or Wi-Fi only, or manually disable it for high-drain apps like Facebook, LinkedIn, or TikTok.

3. Reevaluate Your Location Services Settings

Apps like Maps and Uber need real-time location access, but others don’t. To check what’s siphoning power:

Settings > Privacy & Security > Location Services

Switch irrelevant apps to “While Using the App” or “Never.” This not only extends battery life but also improves privacy.

4. Audit Your Battery Usage

iOS offers a detailed battery usage breakdown. Go to:

Settings > Battery

Here, you can see which apps are the biggest battery hogs. Apps running too often in the background? Consider offloading them or restricting their permissions.

5. Use Dark Mode with OLED Screens

If your iPhone has an OLED display (iPhone X and newer, except XR/SE), using Dark Mode can slightly reduce battery usage. This is because OLED screens only light up colored pixels, and black pixels remain off.

Activate it under:

Settings > Display & Brightness > Appearance > Dark

Schedule it to turn on automatically at sunset for convenience.

6. Limit Notifications and Push Updates

Every time your phone lights up or vibrates, it consumes energy. Go to:

Settings > Notifications

Turn off unnecessary alerts, especially for apps that frequently push non-critical updates. Similarly, under Settings > Mail > Accounts, set your email accounts to Fetch manually instead of Push or Fetch every 15 minutes.

7. Disable Unused Wireless Connections

If you’re not using Bluetooth, AirDrop, or Wi-Fi, disable them. Constant scanning for connections can wear down the battery. Use the Control Center to quickly toggle off unused wireless features.

Also, avoid leaving AirDrop on “Everyone.” Set it to “Receiving Off” or “Contacts Only” when not needed.

8. Update to the Latest iOS

Each iOS update includes performance and battery optimizations. Avoid postponing updates, especially if you’re on an older version. Head to:

Settings > General > Software Update

Install updates over Wi-Fi and ensure your device is sufficiently charged or plugged in during the process.

9. Turn Off Unused System Services

iOS includes several system-level services that run in the background and may not be relevant to most users. Go to:

Settings > Privacy & Security > Location Services > System Services

Disable features like Location-Based Apple Ads, iPhone Analytics, and Popular Near Me to save battery without affecting your experience.

10. Monitor Battery Health and Know When to Replace

Over time, batteries chemically age, which reduces their maximum capacity. You can check your battery’s health under:

Settings > Battery > Battery Health & Charging

If Maximum Capacity is below 80%, or you see a warning, it might be time for a battery replacement. This is especially important if you rely on health-tracking features like the Apple Watch, which also demands iPhone support for optimal functionality.

Final Thoughts

By making just a few of these strategic adjustments, you can significantly boost your iPhone’s battery life and improve daily reliability. The key is awareness—knowing which settings matter and how your apps behave in the background.

While Apple continues to refine iOS for energy efficiency, smart usage habits still play a vital role. Whether you’re navigating a busy workday or a long flight, these tips ensure your iPhone keeps up without constantly reaching for the charger.
