Common iOS 18 Battery and Charging Problems

One of the most frequent complaints about iOS 18 involves battery performance and charging behavior. These iOS 18 bugs can significantly impact how long your device lasts between charges and how reliably it powers up.

Rapid Battery Drain in iOS 18

Many users have noticed their iPhone battery draining much faster after installing iOS 18. This is one of those iOS 18 glitches that seems to affect a wide range of devices. Your iPhone might be performing background tasks like re-indexing files or updating applications, which can consume additional power temporarily.

If you’re experiencing unusually quick battery depletion, try these solutions:

Activate low power mode through your settings
Disable Bluetooth when not in use
Enable Optimized Battery Charging
Restrict location access for non-essential apps
Wait for subsequent iOS updates that might address these battery issues

Charging Difficulties and Limitations

Some users report their iPhones won’t charge beyond 80% after the iOS 18 update, even when the charging limit feature isn’t enabled. These charging-related iOS 18 bugs can be particularly problematic when you need a full battery for extended use.

To address charging problems:

Disable Optimized Battery Charging temporarily
Try different charging cables or power sources
Unplug and reconnect your charging cable
Reduce reliance on wireless charging

iPhone Overheating During Charging

While some warmth during charging is normal, excessive heat can indicate underlying iOS 18 bugs. If your device becomes uncomfortably hot while charging, it could affect both performance and long-term battery health.

Solutions for overheating issues:

Use only Apple-certified charging accessories
Remove your phone case during charging sessions
Avoid charging in hot environments
Close background applications before charging

Performance Issues and iOS 18 Glitches

Beyond battery concerns, many users are reporting performance-related problems after updating to iOS 18. These iOS18 bugs can make your device feel slower or less responsive than before the update.

System Lag and Slow Performance

The smooth, responsive interface that iPhone users appreciate can sometimes degrade after major updates. If your device feels sluggish or unresponsive, you might be experiencing one of the more common iOS 18 glitches.

To improve performance:

Force restart your device
Free up storage space by removing unnecessary files
Close apps running in the background
Check for app updates that might be optimized for iOS 18

Overheating During Normal Use

Some users find their iPhones become unusually warm during everyday tasks after updating to iOS 18. This isn’t just one of those minor iOS 18 bugs—it can affect your device’s performance and comfort during use.

If your iPhone overheats during regular operation:

Update all your applications
Perform a force restart to clear temporary files
Disable unnecessary features
Monitor your battery health in Settings
Wait for future iOS updates that may resolve heating issues

Touch Screen Responsiveness Problems

Another category of iOS 18 glitches involves the touch screen becoming less responsive or completely unresponsive at times. This can manifest as delayed responses to touches, parts of the screen not registering input, or the device freezing entirely.

Potential solutions for touch screen issues:

Clean your screen thoroughly
Perform a force restart
Check for physical damage to the screen
Reset all settings (back up first)
Restore your device to factory settings as a last resort

System-Level iOS 18 Bugs and Errors

Some of the more concerning issues reported involve core system functionality. These iOS 18 bugs can prevent your device from starting properly or cause unexpected behavior during use.

Startup Problems and Black Screen Issues

If you encounter a black screen:

Attempt a force restart
Try restoring your device through recovery mode
Use DFU mode for more serious system issues

Unplanned Restarts and Boot Loops

Some users report their iPhones restarting unexpectedly or getting stuck in boot loops after the iOS 18 update. These iOS 18 glitches can interrupt your workflow and cause data loss if they occur during important tasks.

Addressing random restarts:

Reinsert your SIM card
Restore your device using iTunes/Finder
Reset all settings
Check for specific app conflicts

Recovery Mode Problems
