Is your iPhone battery draining faster than usual? As Apple introduces brighter OLED displays, powerful chipsets, and feature-rich iOS updates, keeping your battery charged all day can feel like a challenge.
While everyday battery degradation happens over time, software settings play a massive role in how fast your phone dies. Many long-held tricks—like force-closing background apps—actually hurt your battery life on modern iPhones.
If you want to maximize your daily battery life and extend your overall battery health, here are 13 updated tips and settings adjustments that actually work.
1. Identify Battery Hogging Apps
Before changing dozens of settings, find out what is draining your power. iOS has built-in diagnostics that break down energy consumption per app.
- Go to Settings > Battery.
- Scroll down to view Battery Usage By App.
- Toggle between Last 24 Hours and Last 10 Days to spot apps running high background activity.
If an app you rarely use shows heavy background consumption, consider deleting it or tweaking its individual permission settings.
2. Stop Force-Closing Apps in the App Switcher
One of the most common iPhone myths is that swiping away apps saves power. In reality, force-closing apps hurts your battery life.
Modern iOS freezes background apps in a suspended state where they consume minimal RAM and zero CPU power. When you force-close an app and reopen it later, your iPhone’s processor has to reload all data from scratch, using significantly more energy than leaving it in the background. Only force-close an app if it freezes or stops responding.
3. Manage Background App Refresh
Background App Refresh allows apps to check for new data (like social media feeds or weather updates) even when you aren't using them. Keeping this enabled across dozens of installed apps will steadily drain power throughout the day.
- Go to Settings > General > Background App Refresh.
- Switch the setting to Wi-Fi Only or turn it off entirely for individual apps that do not require real-time background updates.
4. Enable Low Power Mode (and Automate It)
Low Power Mode reduces background activity, lowers display brightness, disables visual effects, and caps performance to stretch your remaining power. While you can toggle it on manually from the Control Center when your battery drops below 20%, you can also automate it.
- Open the Shortcuts app on your iPhone.
- Tap Automation > New Automation.
- Select Battery Level, choose a trigger point (e.g., Falls Below 40%), and set it to turn on Low Power Mode automatically.
5. Adjust Screen Brightness and Auto-Lock
The display is consistently the single largest consumer of battery power on any smartphone.
- Lower Brightness: Swipe down to open the Control Center and manually pull down the brightness slider.
- Enable Auto-Brightness: Ensure your phone adjusts dynamically based on ambient light by checking Settings > Accessibility > Display & Text Size > Auto-Brightness.
- Reduce Auto-Lock Time: Set your display to turn off quickly when idle by going to Settings > Display & Brightness > Auto-Lock and selecting 30 Seconds or 1 Minute.
6. Audit Location Services (GPS Usage)
GPS tracking consumes significant power. While apps like Maps or Rideshare apps need exact location data, games and retail apps rarely do.
- Go to Settings > Privacy & Security > Location Services.
- Change permissions for non-essential apps from Always to While Using the App or Never.
- Disable Precise Location for apps that don't need exact coordinates (like weather apps or local news).
7. Switch from Push to Fetch for Email
If your iPhone constantly checks email servers every few seconds for new messages, the wireless radios remain active in the background.
- Go to Settings > Mail > Accounts > Fetch New Data.
- Turn off Push.
- Set Fetch to Every 15 Minutes, Every 30 Minutes, or Manually. Fetching periodically or manually opening the app to refresh will save noticeable battery over a full day.
8. Optimize Display Settings (Dark Mode & Always-On Display)
If your iPhone features an OLED screen (iPhone 12 and newer), using Dark Mode saves energy because dark pixels turn off completely instead of emitting light.
- Turn on Dark Mode: Go to Settings > Display & Brightness and select Dark.
- Tweak Always-On Display (Pro Models): If you use an iPhone Pro model, go to Settings > Display & Brightness > Always On Display and toggle off Show Wallpaper or disable the feature completely to prevent passive battery drain while your phone sits idle.
9. Silence Non-Essential Push Notifications
Every push notification wakes up your screen and activates your phone's cellular or Wi-Fi radio. If dozens of apps ping you continuously throughout the day, the cumulative battery drain adds up fast.
- Go to Settings > Notifications.
- Select non-urgent apps and turn off Allow Notifications.
- Alternatively, enable Scheduled Summary to receive non-critical notifications bundled together at specific times of the day rather than continuously.
10. Limit System Haptics and Vibration Motors
Vibration motors require physical energy to move, using significantly more power than playing a simple sound tone.
- Turn off Keyboard Haptics: If you don't need tactile feedback while typing, go to Settings > Sounds & Haptics > Keyboard Feedback and turn off Haptic.
- Disable System Haptics: Scroll down in Settings > Sounds & Haptics and toggle off System Haptics.
11. Manage Connectivity Settings (5G, Wi-Fi, and Bluetooth)
Searching for cellular or Wi-Fi signals in weak coverage areas forces your iPhone’s modem to work at maximum power output.
- Set 5G to Auto: Go to Settings > Cellular > Cellular Data Options > Voice & Data and select 5G Auto. This lets your iPhone fall back to LTE when high 5G speeds aren't necessary, preserving power.
- Use Wi-Fi Over Cellular: Wi-Fi radios use less power than cellular connections to transmit data. Connect to trusted Wi-Fi networks when static.
- Turn on Airplane Mode in Low Coverage: If you are in a location with weak or zero cellular signal (like a basement or rural trail), turn on Airplane Mode so your phone stops constantly hunting for service.
12. Enable Optimized Battery Charging
To preserve long-term battery capacity and prevent fast degradation, manage how your device charges overnight.
- Go to Settings > Battery > Battery Health & Charging.
- Ensure Optimized Battery Charging (or 80% Limit on newer models) is toggled on.
This feature learns your daily charging routine and delays charging past 80% until right before you typically unplug, keeping the battery out of high-stress voltage ranges.
13. Keep iOS Updated
Apple regularly releases system updates containing bug fixes, modem optimizations, and power management improvements.
- Go to Settings > General > Software Update.
- Make sure your iPhone is running the latest available iOS build to benefit from overall stability fixes.
Key Takeaways
Fixing fast battery drain on an iPhone comes down to reducing unnecessary background activity, limiting display power draw, and fine-tuning hardware settings like GPS and cellular radios. By adjusting a few permissions and adopting habits like keeping Dark Mode active, you can extend your daily battery life without losing essential phone capabilities.
