Your iPhone is your lifeline. It wakes you up, keeps you connected, helps you navigate the world, and provides entertainment on the go. But nothing is more frustrating than watching your battery percentage drop rapidly when you’re only halfway through the day. Fortunately, saving battery life on an iPhone isn’t complicated—it just takes a few tweaks and smarter habits.
In this guide, you’ll discover powerful, effective, and safe ways to improve iPhone battery life, whether you’re using the latest model or an older device. These tips are suitable for casual users, professionals, students, and anyone who wants to get more out of their battery without sacrificing performance.
Why Does iPhone Battery Drain So Fast?
Before jumping into solutions, it’s important to understand what causes your battery to drain quickly.
Common Reasons for Fast Battery Drain:
- Screen brightness too high
- Constant app refresh in the background
- Location services running non-stop
- Push email and notifications from multiple apps
- Poor signal strength (searching for connection)
- Unoptimized settings or outdated iOS
Knowing what’s eating your battery is the first step toward fixing it. Now let’s go through the best methods to extend your iPhone’s battery life.
1. Use Low Power Mode Wisely
Low Power Mode is the fastest way to save energy on your iPhone. It temporarily reduces background activity like mail fetch, automatic downloads, and visual effects.
How to Enable It:
- Go to Settings > Battery
- Toggle on Low Power Mode
You can also add it to your Control Center for quick access.
🔋 Use it when your battery drops below 50% or anytime you’re not charging your phone.
2. Turn Off Background App Refresh
Apps running in the background use energy even when you’re not using them. Disabling this feature can make a huge difference.
How to Turn It Off:
- Go to Settings > General > Background App Refresh
- Select Off or choose Wi-Fi only if you still want background activity while connected.
🛑 Focus on disabling it for social media, news, and shopping apps, which are often the biggest offenders.
3. Manage Location Services
Some apps constantly access your location—even when you’re not using them—which drains your battery.
How to Adjust Location Settings:
- Go to Settings > Privacy & Security > Location Services
- Review each app and set it to:
- Never
- Ask Next Time
- While Using the App (preferred)
📍 Avoid “Always” unless it’s essential for apps like navigation or fitness tracking.
4. Reduce Screen Brightness
Your iPhone’s screen is one of the biggest battery hogs.
What You Can Do:
- Go to Settings > Display & Brightness
- Reduce Brightness or turn on Auto-Brightness
You can also access brightness from Control Center with a quick swipe.
💡 Dimming your screen can extend battery life significantly, especially on OLED models like iPhone X or later.
5. Disable Push Email
Emails syncing in real time is convenient—but it also consumes a lot of power.
How to Fix It:
- Go to Settings > Mail > Accounts > Fetch New Data
- Turn off Push
- Set Fetch to Every 30 minutes, Hourly, or Manually
✉️ Manual fetch ensures emails are only checked when you open the app, which saves the most energy.
6. Update Your iPhone to the Latest iOS
Apple regularly releases updates that improve battery efficiency and fix bugs.
To Update:
- Go to Settings > General > Software Update
- Install the latest version
⚙️ Don’t skip updates—they often contain battery optimization improvements.
7. Turn Off Unnecessary Notifications
Every time your screen lights up from a notification, it uses power. Reduce this by limiting which apps are allowed to push notifications.
How:
- Go to Settings > Notifications
- Choose apps that don’t need to alert you and turn off Allow Notifications
📵 Especially silence updates from apps like games, sales alerts, and news pop-ups.
8. Disable Vibrations and Haptic Feedback
Believe it or not, those small vibrations when typing or receiving alerts can drain your battery faster than you think.
Disable It:
- Go to Settings > Sounds & Haptics
- Turn off Vibrate on Ring and Vibrate on Silent
- Also turn off System Haptics
🤫 Less buzz means more juice.
9. Use Wi-Fi Instead of Cellular When Possible
Wi-Fi uses less power than mobile data, especially in areas with weak signal strength.
Tip:
- Connect to a trusted Wi-Fi network at home, work, or in cafes.
- Turn off Cellular Data when you don’t need it (Settings > Cellular).
📶 Poor signal forces your phone to work harder, which increases battery usage.
10. Limit Widgets and Live Wallpapers
Widgets constantly update in the background. Live wallpapers also consume energy due to motion and animation.
Optimize It:
- Long press on your Home Screen
- Remove unnecessary widgets
- Go to Settings > Wallpaper and select a static image
🎨 Less motion = less energy drain.
11. Enable Dark Mode
If your iPhone has an OLED display (iPhone X or newer), Dark Mode can help save battery by using less light on dark pixels.
Turn It On:
- Go to Settings > Display & Brightness
- Select Dark
🌚 Bonus: It’s also easier on your eyes in low light environments.
12. Stop Siri From Always Listening
Siri’s voice activation feature (“Hey Siri”) keeps your microphone partially active, which can drain battery.
Turn Off:
- Go to Settings > Siri & Search
- Toggle off Listen for “Hey Siri”
You can still access Siri manually with the Side or Home button.
13. Turn Off Auto-Downloads and App Updates
Auto-updating apps and downloading music or podcasts in the background can chew through battery life.
Control It:
- Go to Settings > App Store
- Turn off App Updates and Automatic Downloads
⏳ Update apps manually when you’re on Wi-Fi and have plenty of battery.
14. Restart Your iPhone Occasionally
Restarting clears background processes and resets memory usage. It’s a simple trick that can sometimes improve battery behavior.
How to Restart:
- For iPhones with Face ID: Press and hold Side button + Volume Down, then slide to power off.
- For older models: Hold the Power button, then slide to turn off.
Wait a few seconds, then turn it back on.
15. Monitor Battery Usage Per App
Sometimes a single app may be draining most of your battery. Check your battery stats to find out.
How:
- Go to Settings > Battery
- Scroll down to see which apps use the most power
📊 If an app is consuming an unusually high percentage, consider updating, deleting, or limiting its use.
Bonus Tips to Extend Battery Lifespan (Not Just Life Per Charge)
There’s a difference between battery life (daily use) and battery lifespan (long-term health). Here’s how to preserve your battery’s health over time:
1. Avoid Extreme Temperatures
Keep your phone between 0°C and 35°C. High heat is especially damaging.
2. Don’t Keep Your Battery at 100% or 0%
Try to stay between 20% and 80% for optimal battery health.
3. Use Optimized Battery Charging
Go to Settings > Battery > Battery Health & Charging and enable Optimized Battery Charging.
This feature slows down charging after 80% and learns your habits to reduce wear.
Signs Your Battery Might Need Replacing
If you’ve tried all the above tips and still notice terrible battery performance, it could be a sign of battery degradation.
How to Check:
- Go to Settings > Battery > Battery Health & Charging
- Look at Maximum Capacity
- If it’s below 80%, your battery is significantly worn.
You may need a battery replacement to restore peak performance and battery life.
Final Thoughts
