1. Reduce the screen brightness and shorten the automatic locking time; 2. Turn off unnecessary background application refresh and location services; 3. Reduce the frequency of push notifications and email acquisition; 4. Turn off hand-up wake-up, reduce animations and turn off Wi-Fi and Bluetooth in time; 5. Keep the system updated and monitor the health of the battery. These settings and adjustments can significantly extend the battery life of the iPhone, especially for older models, which can eventually get several more hours of use.

One of the most common frustrations with iPhones—especially older models—is battery life. While Apple designs its devices for efficiency, daily usage habits and settings can significantly impact how long your battery lasts. The good news is that you don't need to replace your phone or install third-party apps to see improvements. With a few smart adjustments, you can extend your iPhone's battery life noticeably.

1. Adjust Screen Brightness and Timeout

The display is one of the biggest battery consumers on any iPhone. Reducing screen brightness and how long it stays on can make a big difference.

• Go to Settings > Display & Brightness and lower the brightness manually or enable Auto-Brightness (Settings > Accessibility > Display & Text Size) so the phone adjusts based on ambient light.
• Shorten the auto-lock time: Settings > Display & Brightness > Auto-Lock . Choose 30 seconds instead of “Never” or 5 minutes.

Even better, use Dark Mode if you have an OLED iPhone (iPhone X and later). Black pixels use less power on these screens.

2. Manage Background App Refresh and Location Services

Many apps continue working in the background, checking for updates or tracking your location—even when you're not using them.

• Turn off unnecessary Background App Refresh :
  Settings > General > Background App Refresh . You can disable it entirely or allow it only for essential apps.

  

• Limit Location Services :
  Settings > Privacy & Security > Location Services . For apps that don't need constant access (like social media or weather), set them to "While Using" instead of "Always." Some apps even let you choose "Ask Next Time," giving you more control.

Also, disable Precise Location for apps that don't need it—this reduces battery drain from GPS tracking.

3. Reduce Push Notifications and Email Fetching

Every notification wakes your screen and uses power. The more alerts you get, the faster your battery drains.

• Cut down on non-essential notifications:
  Settings > Notifications , then go through each app and disable notifications for those you don't need.

• Change how often your email checks for new messages:
  Settings > Mail > Accounts > Fetch New Data . Instead of “Push” or “Fetch,” set it to “Manually” or increase the fetch interval (eg, every hour). This stops your phone from constantly pinging servers.

4. Disable Unnecessary Features and Animations

Some features are convenient but come at a cost to battery life.

• Turn off Raise to Wake :
  Settings > Display & Brightness > Raise to Wake . This stops the screen from lighting up every time you move your phone.

• Reduce motion and animations:
  Settings > Accessibility > Motion > Reduce Motion . This not only helps battery but can improve performance on older devices.

• Disable Wi-Fi and Bluetooth when not in use. Even if not connected, they constantly search for signals. Use Control Center to turn them off quickly.

5. Keep iOS Updated and Monitor Battery Health

Apple frequently releases updates that improve power efficiency.

• Always install the latest iOS version:
  Settings > General > Software Update .

• Check your battery health:
  Settings > Battery > Battery Health & Charging . If your maximum capacity is below 80%, the battery may need service. An aging battery won't hold charge as well, no matter the settings.

Also, avoid letting your iPhone get too hot or drop below 20% regularly—extreme temperatures and deep discharges shorten battery lifespan.

Basically, most battery drain comes from screen use, background activity, and connectivity features. By making small, consistent changes to how your iPhone operates, you can gain an extra few hours of use per charge. It's not about drastic measures—it's the little things that add up.
