The iPhone 12 is known for its speed, power, and sleek design. Equipped with the A14 Bionic chip, it was one of the fastest smartphones when it launched. However, if you find yourself asking, "why is my iPhone 12 so slow?", you’re not alone. Over time, even the most powerful devices can start to show signs of lagging. The good news is, most causes are fixable without needing professional help.
In this blog post, we’ll explore the common reasons behind a slow iPhone 12 and offer practical solutions to get your device running smoothly again.
Common Reasons Why Your iPhone 12 Might Be Slow
1. Outdated Software
Apple regularly releases iOS updates that improve performance, fix bugs, and patch security vulnerabilities. If you haven't updated your iPhone in a while, outdated software could be slowing it down.
Each new iOS version is optimized for newer apps and features. Skipping updates can leave your phone struggling to keep up with the latest technology.
Solution:
Go to Settings > General > Software Update and install any available updates.
2. Too Many Background Apps Running
Multitasking is great, but keeping too many apps open in the background can consume memory and processing power, making your iPhone 12 sluggish.
Solution:
Swipe up from the bottom of the screen and pause in the middle to see all open apps. Swipe up on apps you’re not using to close them.
Regularly closing unused apps can free up system resources and enhance performance.
3. Low Storage Space
iPhones need some free storage space to function efficiently. If your storage is almost full, your iPhone 12 may start lagging or becoming unresponsive.
Solution:
Go to Settings > General > iPhone Storage to check your available space.
Delete unnecessary apps, clear Safari cache, offload unused apps, or move photos and videos to iCloud or your computer.
A good rule of thumb is to keep at least 10-20% of your total storage free.
4. Battery Health Issues
As iPhone batteries age, they lose their ability to hold a charge and deliver peak performance. If your battery health has degraded, iOS might automatically slow down performance to prevent unexpected shutdowns.
Solution:
Check your battery health by navigating to Settings > Battery > Battery Health & Charging.
If your Maximum Capacity is significantly lower (like below 80%) or you see a message about performance management, consider replacing your battery at an Apple Store or an authorized service provider.
Battery replacement can breathe new life into a sluggish iPhone.

5. Background App Refresh
Background App Refresh allows apps to update their content even when you're not using them. While convenient, it can also drain system resources and slow down your device.
Solution:
Go to Settings > General > Background App Refresh and turn it off for apps that don't need constant updates.
This can help save battery life and boost performance.
6. Widgets and Live Wallpapers
Widgets and live wallpapers are visually appealing, but they also consume additional memory and processing power.
Solution:
Remove unnecessary widgets by long-pressing on them and tapping Remove Widget.
Opt for static wallpapers instead of dynamic or live options.
Simplifying your Home Screen can lead to a noticeable performance improvement.
7. App Updates
Running outdated versions of apps can lead to compatibility issues and slow performance. Developers constantly optimize apps for newer iOS versions and hardware capabilities.
Solution:
Open the App Store and tap on your profile icon.
Scroll down and update all apps with available updates.
Keeping your apps updated ensures they run efficiently on your iPhone 12.
8. Overheating Issues
If your iPhone 12 gets too hot, it may automatically throttle performance to protect internal components. Overheating can happen when playing graphically intense games, using the phone while charging, or operating in a hot environment.
Solution:
Remove your phone from its case if it’s overheating.
Close resource-heavy apps and allow your device to cool down before using it heavily again.
Avoiding overheating can help maintain consistent performance.
Bonus Tips to Boost Your iPhone 12’s Speed
Restart Regularly: Simply turning your iPhone off and on again once a week can clear cached processes and boost speed.
Reset Settings: If issues persist, try resetting all settings. Go to Settings > General > Transfer or Reset iPhone > Reset > Reset All Settings. This won't delete your data but will revert system settings to default.
Factory Reset: As a last resort, you can back up your data and perform a full factory reset to start fresh.
Conclusion
If you’re wondering, "why is my iPhone 12 so slow," the issue is usually related to software glitches, storage constraints, background apps, or battery health problems. The good news is that with regular maintenance — like updating software, managing storage, and checking battery health — you can keep your iPhone 12 running like new for years.
Taking the time to identify and fix the root cause will not only improve your device's performance but also extend its lifespan. Start with the easier solutions and work your way up — your iPhone 12 will thank you!
