Introduction
Apple’s latest iOS 17.3 update arrives with various bug fixes and performance improvements. However, many users have reported excessive battery drain after installing this update on their iPhones.
Some key complaints include:
- Battery dropping faster than usual
- Needing to charge the phone more frequently
- Low battery warning popping up sooner than expected
This rapid power drain makes it challenging to get through the day without having to plug in your iPhone, which can be frustrating.
While the exact technical cause is unclear, analyzing the battery usage patterns and tweaking settings can help mitigate the battery drain to some extent. This article discusses actionable tips to diagnose and improve iPhone battery life if you face abnormal battery drain after updating to iOS 17.3.
Examining Battery Usage Statistics
The first step is to examine the battery usage statistics on your iPhone to identify any apps or services using excessive power after the 17.3 update.
To view battery usage:
Step#1.Go to Settings > Battery
Step#2.Check the battery usage by app over the last 24 hours or 10 days
Step#3.Make a note of apps using too much power in the background
Additionally, go to Settings > Battery > Battery Health and see if your phone’s Maximum Capacity has dropped below 80%. A worn-out lithium-ion battery could also accelerate power drain.
| Parameter | Normal Value |
| Maximum Capacity | Above 80% |
| Peak Performance Capability | True |
If your battery health metrics seem abnormal, it may be time to replace your iPhone’s old battery using Apple services.
Troubleshooting Tips to Fix Battery Drain
Based on the battery usage analysis, here are some troubleshooting steps to try out:
1. Update to Latest iOS Version
Ensure your iPhone is updated to iOS 17.3.3 or the newest iOS update available. Apple releases incremental updates to fix bugs like battery drain issues.
2. Disable Background App Refresh
Restrict background activity for apps showing high cellular data and battery usage, like social media apps. This limits refreshes and location tracking in the background.
Go to Settings > General > Background App Refresh and switch it off for such apps.
3. Turn Off Display & Auto-Lock Sooner
Shorten your display auto-lock timer for the phone to enter sleep mode sooner when not being used actively. Lower screen brightness levels further to conserve power.
4. Disable Unnecessary Widgets
Widgets constantly refreshing data also reduces battery runtime. Remove any unnecessary widgets from your home screen to limit this.
5. Reset All Settings
If battery drain persists abnormally, try resetting all settings on your iPhone. This will clear up any problematic cached data or push notification-related glitches that may impact power usage negatively.
Go to Settings > General > Reset > Reset All Settings to perform the reset.
When to Consider Replacing Your iPhone Battery
If your iPhone battery health shows Maximum Capacity below 70-80% despite trying the above troubleshooting tips, it indicates battery performance degradation from prolonged usage cycles.
You will likely keep facing faster battery drain issues during intensive usage unless you get the old lithium-ion battery replaced.
Apple recommends replacing iPhone battery when its health drops below 80% of original capacity for optimal performance. So don’t delay battery replacement if you notice problems like abrupt device shutdowns or really short backup on full charge.
Conclusion
While iOS 17.3 seems to have led to rapid battery drain for select iPhone models, there are a few helpful techniques you can try before thinking about a battery replacement.
Analyze battery usage, turn off background activity for apps showing high usage, lower screen brightness, and reset all settings to see if it resolves your faster battery drain concerns.
Update to the newest iOS version promptly as Apple rolls out incremental updates addressing battery optimization issues.
If your iPhone battery health is already degraded, it is advisable to get the lithium-ion battery replaced for lasting performance. This will likely fix unstable battery life in the long run.
