This walkthrough will take you through solutions that have worked for us in the past. They’ll help you maintain a fast, and efficient, iPhone 13 in the future.
Restart Your iPhone 13
If you’re running into performance issues on your iPhone 13, iPhone 13 mini, iPhone 13 Pro, or iPhone 13 Pro Max, try restarting your device. Often times a quick reboot will iron out the problems.
Power down your phone, leave it off for 30 seconds or so, and then power it back on and see if performance improves. If it doesn’t, you’ll want to try the solutions below.
Update Your iPhone 13
Apple will continue to push out new iOS 17 software. Point updates (iOS x.x.x) are almost always focused on fixing bugs while milestone upgrades (iOS x.x) typically deliver a mix of new features and bug fixes.
Apple may not call out performance fixes in an update’s change log, but new software always has the potential to help (or hurt) your iPhone 13’s overall performance.
For more on the latest version of iOS 17, check out our guide.
Update Your Apps
If you’re having performance issues, try updating your applications to the latest version if an update is available.
App developers are rolling out support updates and they could help stabilize the app and/or your iPhone’s performance.
Before you install the latest version of an app, make sure you dig into reviews from other iPhone 13 users. If the reviews are mostly good, download the latest version.
Reset Your Settings
You can also try resetting your iPhone 13’s settings. This will restore your phone’s settings to their factory defaults so make sure you have your Wi-Fi passwords handy. You’ll need to re-enter them when the process completes.
- Go to Settings.
- Tap General.
- Tap Transfer or Reset iPhone.
- Tap Reset.
- Tap Reset All Settings.
- Enter your passcode if you have one enabled.
This could take a few seconds to complete so remain patient.
Cleanup Your Storage
If you transferred files from an old phone to your iPhone 13, you probably have a ton of clutter taking up space on your internal storage. Getting rid of these unused files and apps could help improve your iPhone’s performance.
If you decide to do some cleanup, you’ll want to check and see how much space is available on your iPhone 13 model. Here’s how to do that:
- Head into Settings.
- Tap General.
- Tap Storage & iCloud Usage.
- Select Manage Storage.
If you’re getting close to reaching your device’s storage threshold, you’ll want to head back into General and go to where it says iPhone Storage. This will show you a detailed rundown of your data.
Apple will make some recommendations based on the utilization of your device’s storage, but you can also just go through each section manually delete files you no longer need.
Clear Browser Cookies & Data
Clearing your browser’s cookies and data will free up memory which could have a positive impact on your phone’s overall performance.
If you use Apple’s Safari browser, here’s how to clear them:
- Go to the Settings app.
- Tap Safari.
- Scroll down to where it says Clear History and Website Data. Tap on it.
Tapping this will remove your browsing history, cookies, and other data from Safari. History will also be cleared from any devices signed into your iCloud account. If you’re up for that, tap Clear History and Data again.
If you use Google’s Chrome browser on your iPhone 13, here’s what you need to do:
- Head into the app.
- Tap the three horizontal circles in the bottom right corner. They’re in the top right corner if you haven’t updated to Chrome’s new design.
- Tap Settings.
- Tap Privacy.
- Now tap Clear Browsing Data.
You can now select what you want to delete. If you’re noticing heavy lag, you might want to clear out everything and start from scratch.
Check Your SIM Card
If your iPhone 13 is randomly rebooting itself, try removing your SIM card. You’ll need a paperclip (or something like it) or a SIM removal tool to eject it.
If you no longer run into the problem with the SIM card removed, put it back in and monitor your phone’s performance.
If you run into the issue again, try hard resetting your iPhone 13 with the SIM card removed and then putting the SIM card back in after the phone boots back up.
Downgrade
If you recently installed a new version of iOS 17 on your iPhone 13 and you started noticing issues soon thereafter, you could try moving your iPhone 13’s software back to the previous version if the option is available.
If you don’t know how to downgrade your device’s software, have a look at our walkthrough.
Restore
If you can’t find a fix for your performance issue(s), and you want to avoid taking your phone into a store, you might want to restore your iPhone. This should only be used as a last resort.
You can do this via Finder, iTunes, or iCloud.
