Is your iPhone 15 or 15 Plus suddenly feeling like it’s moving in slow motion? Maybe apps are taking forever to open, your keyboard is lagging behind your typing, or everything just feels a bit off. If that sounds familiar, you’re not alone — and no, your phone isn’t secretly plotting against you. iPhone 15 slowdowns can happen for a bunch of reasons, from software glitches and storage overload to background apps hogging resources. The good news? Most of the time, it’s a fixable issue. A quick restart, clearing out some unused apps, or updating to the latest iOS can often make a big difference. Still experiencing iPhone 15 slowdowns after that? It might be time to dig a little deeper — maybe it’s a background process draining your CPU or a setting that needs tweaking.

Why does My iPhone 15 Slowdown?
Several culprits can turn your speedy device into a tortoise:
- Too Many Apps Running: Even if you’re not actively using them, apps running in the background (especially those with Background App Refresh enabled) can hog memory and processing power.
- Software Bugs or Outdated iOS: New iOS updates sometimes introduce glitches, while skipping updates can leave you with unresolved bugs that impact performance.
- Battery Issues: As batteries age, they lose capacity and can trigger iOS to throttle performance to prevent unexpected shutdowns.
- Overheating: Intense gaming, charging, or buggy apps (hello, Instagram and Uber!) can cause your phone to heat up, which leads to automatic slowdowns to protect internal components.
- Storage Nearly Full: If your storage is close to maxed out, your iPhone has less room to operate efficiently, resulting in lag and stutters.
- Background Activity: After major updates or restoring from backup, your phone might be busy indexing and updating in the background, causing temporary slowdowns.
Actionable Tips to Speed Up Your iPhone 15
Ready to give your iPhone a performance tune-up? Try these steps:
Restart Your iPhone
- A simple restart can clear out temporary files and processes bogging down your device.
Free Up Storage
- Go to Settings > General > [Device] Storage to see what’s eating up space.
- Delete unused apps, offload large files, and clear old photos or videos.
- Aim to keep at least 1GB free for smooth performance.
Update iOS and Apps
- Always install the latest iOS updates—these often squash performance bugs and optimize your device.
- Update all your apps in the App Store, especially those known to cause issues.
Close Background Apps (But Don’t Overdo It)
- Swipe up from the bottom and flick away apps you’re not using. However, constantly force-closing apps can actually slow things down, as iOS is designed to manage memory efficiently.
- Focus on closing apps that are frozen or misbehaving.
Reduce Motion and Visual Effects
- Head to Settings > Accessibility > Motion and turn on Reduce Motion. This limits fancy animations that can eat up resources, making your phone feel snappier.
Manage Background App Refresh
- Go to Settings > General > Background App Refresh and disable it for apps that don’t need to update in the background.
Monitor Battery Health
- Check Settings > Battery > Battery Health. If your battery’s maximum capacity is low or you see a message about degraded performance, consider a battery replacement.
Keep Your iPhone Cool
- Avoid using your phone in hot environments.
- Remove the case during charging or heavy use to help heat dissipate.
Limit Widgets and Live Activities
- Too many widgets or live activities on your Home and Lock screens can sap performance. Remove any you don’t use regularly.
When to Seek Professional Repair
If you’ve tried all the above and your iPhone 15 is still stuck in slow motion, it might be time for expert help. Consider a visit to Apple Support or an authorized service provider if:
- Your phone is overheating frequently or shuts down unexpectedly.
- There’s persistent lag even after a factory reset and software updates.
- Battery health is significantly degraded and you see performance management applied.
- You experience hardware issues (e.g., unresponsive touchscreen, random black screens, or physical damage).
Conclusion
The iPhone 15 slowdowns can be frustrating, but they’re usually fixable with a little care. Clearing out unused apps, updating your software, and keeping background activity in check can go a long way in keeping things smooth. Remember, even the most advanced phones need a little maintenance now and then. If you’re still running into iPhone 15 slowdowns after trying everything, don’t stress—Apple’s support team is always ready to help. With just a bit of effort, you can get past those iPhone 15 slowdowns and enjoy the fast, seamless experience your device was built to deliver.

If your iPhone 15, 15 Pro, or 15 Pro Max has been heating up like it’s trying to cook breakfast in your pocket, you’re definitely not the only one. Since its release, a growing number of users have been dealing with iPhone 15 overheating issues — sometimes during charging, other times while gaming, and even when casually scrolling through Instagram or TikTok. So, what’s behind all this unexpected heat? The iPhone 15 overheating problem seems to be linked to a mix of factors — intensive background processes, charging with high-powered adapters, and certain apps pushing the phone’s performance to the limit. Apple has acknowledged the issue and rolled out software updates aimed at reducing the heat by optimizing how the phone manages resources. Still, if your phone feels too hot to handle, there are steps you can take. Avoid charging while using the device heavily, close out power-hungry apps running in the background, and keep your phone out of direct sunlight. While updates are helping, the iPhone 15 overheating concern hasn’t disappeared completely — so it’s worth staying mindful until Apple (hopefully) cools things down for good.

Why Is My iPhone 15 Overheating?
Software Bugs and iOS 17
Shortly after the iPhone 15 series launched, users began noticing their phones heating up — sometimes to the point of being too hot to touch. Apple quickly acknowledged the problem, pointing the finger at a bug in iOS 17 and certain third-party apps (like Instagram, Uber, and Asphalt 9) that were overworking the processor. The good news? Apple rolled out iOS 17.0.3 to squash these bugs and cool things down.
Heavy App Use and Gaming
The iPhone 15 Pro’s A17 Pro chip is a powerhouse, but all that muscle generates heat — especially during intense gaming sessions or when running demanding apps. Prolonged use can push temperatures into the uncomfortable zone, sometimes triggering automatic performance throttling to protect the hardware.
Charging (Especially Fast Charging)
Many users noticed overheating while charging, particularly with fast chargers. The left side and back of the phone (where the logic board sits) tend to get hotter. The good news: the heat typically drops off after reaching about 70% charge, but it can still be alarming.
Background Activity and Initial Setup
When you first set up your iPhone 15 or restore from a backup, the phone is busy indexing, downloading, and updating in the background — leading to extra heat. This is expected to subside after a day or two.
Apple’s Response: iOS 17.0.3 and Beyond
Apple addressed the overheating issue with the iOS 17.0.3 update, stating it “addresses an issue that may cause iPhone to run warmer than expected.” The update targeted the software bug and worked with app developers to optimize problematic apps. Apple clarified that the titanium frame and new design weren’t to blame — in fact, the new materials help dissipate heat better than before. If you haven’t updated yet, now’s the time!
