If your iPhone is feeling slow—apps take longer to load, animations lag, or the keyboard isn’t responsive—you’re not alone. Over time, all devices experience performance issues due to storage limits, outdated software, or even battery degradation. The good news is, you can usually speed up a slow iPhone with a few quick adjustments and settings.

This guide offers practical tips to boost your iPhone’s speed, whether you’re using an older model or a recent one that’s feeling sluggish.
🔍 Common Causes of a Slow iPhone
Before we get to the solutions, here are typical reasons your iPhone might be running slowly:
- Low storage space
- Too many apps running in the background
- Old or buggy software
- Aging battery with performance throttling
- Heavy visual effects and widgets
- Overloaded Safari cache and app data
✅ 15 Tips to Speed Up a Slow iPhone
Restart Your iPhone
Sometimes, a simple restart can flush out temporary system issues or memory leaks.
- How: Hold the power + volume button (Face ID models) or side button (Touch ID models), then slide to power off. Wait 10 seconds and turn it back on.
Update iOS and Apps
Outdated software can cause compatibility problems and bugs.
- Go to Settings > General > Software Update and install the latest iOS version.
- Also open the App Store > Profile Icon > Update All apps
Free Up Storage Space
Low storage can severely slow down your iPhone.
- Go to Settings > General > iPhone Storage to see what’s taking space.
- Delete:
- Large videos/photos
- Unused apps
- Old message threads and attachments
- Enable iCloud Photos or Offload Unused Apps
📌 Keep at least 5–10 GB free for optimal performance.
Disable Background App Refresh
This feature keeps apps updated in the background but can eat up memory and battery.
- Go to Settings > General > Background App Refresh > Off
- Or choose “Wi-Fi” to limit background activity to Wi-Fi only
Clear Safari Cache and Website Data
Too much browser data can cause Safari and system lag.
- Go to Settings > Safari > Clear History and Website Data
Turn Off Motion Effects and Animations
Fancy transitions and motion use CPU resources.
- Go to Settings > Accessibility > Motion
- Turn on Reduce Motion
- Also enable Reduce Transparency under Display & Text Size
Limit Widgets on Home Screen
Widgets update in real-time and consume resources.
- Long-press a widget and select Remove Widget for any non-essential ones
- Avoid using multiple battery or weather widgets
Close Unused Apps
While iOS handles multitasking well, too many open apps can still affect speed.
- Swipe up from the bottom (or double-press the Home button) and swipe away unused apps
Disable Automatic Downloads and Updates
Automatic content syncing can slow your phone in the background.
- Go to Settings > App Store
- Turn off App Updates, App Downloads, and Automatic Downloads
Reduce Notifications
Too many push notifications can keep your phone constantly waking.
- Go to Settings > Notifications
- Turn off alerts for apps you don’t need real-time updates from
Use Low Power Mode (Even at High Battery)
Low Power Mode reduces background tasks and improves responsiveness.
- Go to Settings > Battery > Low Power Mode
- Or add it to Control Center for easy access
Delete Old Messages Automatically
Overloaded Messages app can slow the phone.
- Go to Settings > Messages > Keep Messages
- Change it from Forever to 30 Days or 1 Year
Reset All Settings (Without Data Loss)
This resets system settings but keeps your files and apps.
- Go to Settings > General > Transfer or Reset iPhone > Reset > Reset All Settings
Check Battery Health
A degraded battery can lead to performance throttling.
- Go to Settings > Battery > Battery Health & Charging
- If Maximum Capacity is below 80% or Performance Management is on, consider a battery replacement
🛠 If you see a warning like “Battery health degraded”, this can directly affect performance.
Factory Reset as a Last Resort
If all else fails, doing a clean reset can remove system bugs.
- Back up to iCloud or iTunes
- Go to Settings > General > Transfer or Reset iPhone > Erase All Content and Settings
⚠️ Only do this if you’ve tried all other options.
📱 Is Your iPhone Too Old?
If your iPhone is more than 5–6 years old, slowdowns might be due to outdated hardware. In that case:
- Keep animations and background activity to a minimum
- Use Low Power Mode all the time
- Consider upgrading if iOS updates are no longer supported
✅ Summary: Make Your iPhone Run Faster
Speeding up your iPhone is usually a matter of cleaning up storage, disabling extra features, and keeping software updated. Older iPhones benefit most from trimming background activity, reducing visual effects, and monitoring battery health.
