iOS 17.2 battery drain brought exciting new features like interactive widgets and enhanced Siri capabilities, but some users have reported severe battery drain after updating. If your iPhone or iPad is losing power faster after installing iOS 17.2, there are several troubleshooting steps you can try to restore normal battery life.

1. Update All Apps
Outdated apps are a common source of battery drain. Developers regularly release updates to optimize power efficiency.
To update apps:
- Open the App Store
- Tap your profile icon
- Scroll to see apps with available updates and tap “Update” next to each one
Give your device some time after updates to index new data. Fully quitting apps can also give some temporary relief.
2. Enable Low Power Mode
Low Power Mode reduces background activity and some visual effects to conserve energy. Enabling this can provide several extra hours of battery when needed.
To enable Low Power Mode:
- Open Settings
- Tap “Battery”
- Toggle on “Low Power Mode”
Keep this disabled when not needed to maintain full functionality.
3. Check for Faulty Apps
Roguge apps consuming excessive resources in the background are a prime suspect for battery drain.
To identify problematic apps:
- Open Settings
- Tap “Battery”
- Review battery usage for each app over the past 24 hours
Unsually high usage may indicate a glitched app stuck in a loop. Force quitting via multitasking can provide temporary relief. For persistent issues, deleting and reinstalling the app is advised.
4. Reset All Settings
Resetting all device settings clears temporary glitches while retaining your data and content. This can dislodge stuck processes causing battery drain.
To reset settings:
- Open Settings
- Scroll down and tap “General”
- Tap “Reset”
- Tap “Reset All Settings”
Your device will restart with default settings, allowing you to reconfigure as needed. This preserves all user data.
5. Wait for Next iOS Software Update
Since this is a newly reported issue after a major iOS release, Apple may soon release an incremental update like 17.2.1 to address problems.
It’s advisable to:
- Keep automatic updates enabled in Settings > General > Software Updates
- Periodically check for new updates via Settings > General > Software Updates
Installing the latest iOS version can deliver battery optimizations.
6. Downgrade iOS (If Applicable)
If your battery life has taken an extreme hit, downgrading to the previous iOS 16.x version could provide temporary relief while awaiting a permanent fix.
To downgrade:
- Backup device via iCloud or iTunes
- Download desired iOS IPSW file
- Connect device to computer
- Open Finder or iTunes and inititate restore/downgrade
Note that downgraded devices cannot be directly updated back to 17.2 once a new update is availalbe. A full restore via computer will be required to return to iOS 17.
7. Check Battery Health
All rechargeable batteries have a limited lifespan. If your iPhone battery exceeds 500 charge cycles and holds less than 80% of its original max capacity, instability and faster power drain may occur.
You can check your battery’s condition via Settings > Battery > Battery Health.
If your battery fails to retain sufficient charge, contact Apple Support about potential replacement options depending on device age and warranty status.
8. Utilize iOS System Repair Tool
Apple provides an official iOS Repair Assistant tool for Windows and Mac to address common software issues before seeking in-person service.
This can fix problems caused by failed installations and updates that may contribute to rapid battery drain.
To use the Repair Assistant:
- Download from Apple’s Support site
- Connect device to computer via USB
- Run the Repair Assistant program
- Follow on-screen steps to analyze device and correct issues
This will not delete or modify user data. Multiple repair attempts may be required.
9. Give it Time
It’s important to remember that major iOS updates bring significant behind-the-scenes changes. In the first few days after upgrading, your device will be very busy re-indexing data, syncing information, learning usage patterns and refining memory management.
Allow about a week after updating to iOS 17.2 so that all of these post-update processes can fully complete. Monitoring daily battery drain percentages during this period will determine if the issue persists.
10. Disable Background App Refresh
Background App Refresh allows apps to update content in the background when not in active use. Disabling this can provide moderate battery savings by reducing behind-the-scenes activity.
To turn off Background App Refresh:
- Go to Settings
- Tap General
- Tap Background App Refresh
- Select either “Off” or “Wifi”
Note that some app notifications may be delayed with this disabled. It can be re-enabled later if disabling provides no noticeable battery improvement.
11. Turn Off Widgets
The new iOS 17 interactive widgets offer delightful at-a-glance information, but constantly updating data can impact battery life. Consider temporarily disabling widgets if drain seems excessive.
To disable Today View widgets:
- Swipe rightmost Home screen
- Scroll to bottom
- Tap “Edit”
- Remove widgets as desired
Individual widget reload frequency can also be adjusted under widget edit mode for a custom balance of convenience and battery efficiency. Widgets can always be easily re-added later from the widget gallery.
12. Factory Reset as Last Resort
If no other troubleshooting suggestions have resolved severe battery drain after updating to iOS 17.2, performing a factory reset can wipe all temporary glitches and software issues as a last ditch fix attempt.
To factory reset:
- Backup device via iCloud or iTunes
- Open Settings
- Tap General > Reset
- Tap “Erase All Content and Settings”
This will delete all data and settings, returning device to original out-of-box state so that iOS can be set up again from scratch. Only utilize this method if all other options have failed, as it will remove all non-backed up content.
In Summary
Sudden iOS 17.2 battery drain after an iOS update is frustrating, but often easily fixed. Be sure to methodically try the applicable suggestions above, allowing sufficient time after each step to properly evaluate battery improvements. Avoid any unauthorized services suggesting iOS downgrades below currently signed firmware versions.
For optimal lifetime performance, always keep your iPhone’s operating system, apps and services updated to latest available versions. Reach out to Apple Support if battery issues persist across multiple charging cycles after trying these troubleshooting tips.
