1. Update Apps to Latest Versions
The first step is to ensure all your apps are updated to their latest versions from the App Store. Developers often release quick updates to make their apps fully compatible with the newest iOS versions.
Outdated app code can sometimes cause conflicts and glitches that lead to battery drain. So update all apps and it may automatically resolve any software issues without needing further troubleshooting.
To update your apps:

- Tap your profile icon in the top right corner.
- Scroll down to see all your installed apps and check if any updates are available.

3. Check for Pending iOS Updates
It is also recommended to check if your iPhone is running the latest iOS version. Although you may have updated to iOS 17.2.1, Apple could have released a minor 17.2.x update since then.
New iOS dot updates often contain bug fixes and performance improvements. Installing any pending updates can potentially patch the battery life bug if it was software-related.
To check for and install iOS updates:
- Go to Settings > General > Software Update on your iPhone.
- If an iOS update is available, tap ‘Download and Install’ to upgrade.
Updating to the newest iOS version will ensure your iPhone is running smoother and fix any critical bugs. If the battery drain persists after updating iOS, move on to the next solutions.
4. Adjust Screen Brightness Level
Screen brightness directly impacts iOS 17.2.1 Battery Drain Issue, with higher brightness draining the battery faster. Check if your screen brightness level is set too high and causing the rapid power drain issue after updating to iOS 17.2.1.
You can manually lower the brightness or enable Auto-Brightness so the iPhone sets brightness based on ambient lighting conditions.
To adjust screen brightness:
- Go to Settings > Display & Brightness on your iPhone.
- Drag the brightness slider left to reduce the brightness level.
- Alternatively enable ‘Auto-Brightness’ for automatic adjustments.
Use the lowest brightness comfortable for your eyesight. This simple change can extend your iPhone’s battery life significantly in most cases.
5. Manage Background App Refresh
Apps that run background tasks and refresh content in the background can collectively drain a lot of power. iOS lets you disable Background App Refresh selectively to optimize battery usage.
Check the list of apps allowed to refresh in the background and restrict the ones not absolutely necessary. This prevents unnecessary background activity that could be depleting your battery after upgrading to iOS 17.2.1.
To manage Background App Refresh:
- Go to Settings > General > Background App Refresh.
- Turn off Background App Refresh for apps that don’t need it.
- You can also switch the main toggle off to disable for all apps.
Being selective about background refresh can go a long way in maximizing battery life on your iPhone. Disable the feature for apps that don’t rely on real-time data.
6. Turn Off Location Services
Location services on your iPhone utilize GPS and cellular data to pinpoint your geographic position. While essential for maps, weather and other apps, it can drain battery when used excessively in the background.
If you have enabled location access for too many apps, check if any non-essential apps are using your location and turn it off to conserve power.
To manage location services:
- Go to Settings > Privacy > Location Services.
- Review the list of apps and toggle off location access for apps that don’t require it.
Restricting location access stops unnecessary GPS usage that could be depleting your iPhone’s battery after updating to iOS 17.2.1.
7. Enable Low Power Mode
Low Power Mode is an iOS battery-saving setting that reduces background activity and performance to extend battery life. While it disables some visual effects, the trade-off is worth it when trying to stretch out your iPhone’s battery.
Low Power Mode can provide several additional hours of battery when enabled. Turn it on and see if it resolves the rapid drainage problem on iOS 17.2.1.
To enable Low Power Mode:
- Go to Settings > Battery > Low Power Mode.
- Toggle on Low Power Mode.
Your iPhone will now optimize power usage to make the battery last longer. Low Power Mode also adds a battery percentage indicator to the status bar for reference.
8. Identify and Manage Battery-Draining Apps
Certain apps may have bugs or inefficiencies that cause excess battery usage in the background. You can check battery usage stats by app and take action on top battery hogs.
Go through the list and assess if any app stands out with disproportionately high usage. Try reinstalling or offloading that app, force quitting it when not in use, or deleting and replacing it with an alternative.
To view battery usage by app:
- Go to Settings > Battery > Battery Usage.
- Review the battery usage by app over the last 24 hours or 10 days.
- Manage apps that account for an unusually large share of battery usage.
Pinpointing and controlling battery-intensive apps can optimize your iPhone’s power efficiency after upgrading to iOS 17.2.1.
9. Restart Your iPhone
One of the basic troubleshooting steps for any performance issue on the iPhone is to power it off and on again. Restarting the device essentially flushes out RAM and closes all processes.
For an unknown battery drain bug, restarting your iPhone may do the trick and refresh the iOS system to restore proper power management.
To restart your iPhone:
- Press and hold the Side button and either Volume button until the power off slider appears.
- Drag the slider to turn off your device.
- After the device is powered off, press and hold the Side button again to turn it back on.
If an errant app or system process was causing the battery drain, a restart typically resolves such transient glitches.
10. Reset All Settings
Resetting all settings will restore all your iPhone preferences and settings to factory default. This wipes out any problematic customized settings that may be negatively impacting battery performance after upgrading to iOS 17.2.1.
Resetting settings does NOT delete your data or media, only system preferences. Note down custom settings like wallpaper or Wi-Fi passwords beforehand.
