Check your network conditions
Many apps on your device require an internet connection for their content and other functionality. If the network that you're connected to is congested — for example, at an event with many people using the same network — apps might take a while to open or display their content. Your device can also seem slow as it repeatedly reconnects to new cellular towers when you're in a moving vehicle.
Even if your device indicates a strong signal, you might need to wait, try again in a different location or use available Wi-Fi. If you continue to experience issues with cellular data speed, availability or performance in multiple locations, contact your carrier.
Close an app that's not responding
If an app stops responding or freezes, you might need to force it to close and then open it again.*
- From the Home screen of iPhone X or later or an iPad, swipe up from the bottom of the screen and pause slightly in the middle of the screen. On iPhone 8 or earlier, double-click the Home button to show your most recently used apps.
- Swipe right or left to find the app that you want to close.
- Swipe up on the app's preview to close the app.
* Under normal conditions, force-closing apps is not necessary and does not make your device run faster. In fact, an app takes longer to open after a force close because it has to reload all of its data.
Make sure you have enough storage
If your device is low on storage, iOS or iPadOS automatically frees up space while installing an app, updating iOS or iPadOS, downloading music, recording videos and more. iOS or iPadOS only removes items that can be downloaded again or that aren't needed anymore.
You can check your device's storage in Settings > General > [Device] Storage. For best performance, try to maintain at least 1GB of free space. If your available storage is consistently less than 1GB, your device might slow down as iOS repeatedly makes room for more content.
If you need to free up some space, follow these steps to turn on the storage-saving recommendations built in to iOS or iPadOS:
- Go to Settings > General > [Device] Storage and read the recommendations that iOS or iPadOS might provide.
- Tap Enable to turn on a recommendation, or tap a recommendation title to review the content that you can delete.
If you don't see any recommendations — or if you need to free up even more space — you can review the apps on your device. They're listed on the same [Device] Storage screen along with the amount of space that they use.
Tap an app, then choose from the options:
- Offload the app, which frees up storage used by the app, but keeps its documents and data.
- Delete the app, which removes the app and its related data.
- Depending on the app, you might be able to delete some of its documents and data.
Leave Low Power Mode off when you don't need it
Low Power Mode is an iPhone and iPad feature that extends battery life by reducing the amount of power that your device uses. In Low Power Mode, some features are turned off and some tasks might take longer to complete. If your battery icon is yellow, that means Low Power Mode is on.
Consider leaving Low Power Mode off if you need your iPhone or iPad to function without low-power restrictions. You can turn Low Power Mode on or off in Settings > Battery.
Keep your device from getting too hot or cold
iOS or iPadOS adjusts your device's performance if it becomes too warm due to external conditions, like being left in a hot car or used for an extended time in direct sunlight. Move your device to a cooler location and let its temperature adjust.
Very cold temperatures can also slow your device. If your device runs slowly after being exposed to cold, move it to a warmer location.
Look at your battery health
All rechargeable batteries are consumable components that become less effective as they chemically age. Over time, the rechargeable batteries in all iPhone models will diminish in their capacity and peak performance and will eventually need to be replaced. iOS can show show battery health and recommend if an iPhone battery needs to be replaced. Go to Settings > Battery and tap Battery Health. Battery Health is available only on iPhone.

- A touch screen that responds to taps incorrectly can make your device seem slow. If you think that your touch screen isn't responding correctly, try restarting your iPhone, iPad or iPod touch. If that doesn't work, and the issue occurs in the same area of the screen in multiple apps, you might need to contact Apple Support.
- If you tried these tips and your iPhone, iPad or iPod touch is still slow or continues to freeze, contact Apple Support.
