We have an excellent experience on iOS 15, but some iPhone SE users complain about performance issues including freezing, freezing, general, lag, and random reboots. These problems are very common and you will find them all over Apple’s iPhone line.
If your iPhone SE starts to lag or reboot itself frequently, you don’t need to make an appointment to see a Genius in the Apple Store. Chances are you can fix your performance issues from your home in minutes or seconds.
In this guide, we’re going to show you a few ways to fix iPhone SE performance issues if they happen after an iOS 15 update or out of nowhere.
Restart your iPhone SE
If you start to notice performance issues like lag and freezing, try restarting your iPhone SE. Press and hold the power button, slide to turn it off, leave it off for a minute or so, then turn it back on to check performance.
You can also try resetting the phone by pressing and holding the power and home buttons at the same time until the Apple logo appears.
Update your iPhone SE
If you’re running an outdated version of iOS 15, consider downloading the latest software to your iPhone SE.
To check which version of iOS 15 you are currently using, go to Settings, then About and check under Version. If you’re not running the latest update, you’ll want to upgrade.
To do this, go to Settings, then General, then Software Update. If a new update is available, you will be prompted to download and install new firmware.
Make sure to read reviews before making your move.
Delete what you don’t need
If you’ve owned your iPhone SE for a while, you’ve probably accumulated a ton of data on your device’s internal hard drive. Photos, videos, apps, that sort of thing.
Some people are really good at keeping their device’s hard drive clean, others not so much. If you fall into the latter category, it might be time to investigate your phone’s contents, as clutter can slow down your iPhone.
To do this, go to your iPhone SE settings, go to General and tap iPhone Storage. There you get a detailed overview of what is taking up space on your device.
Go through the list and decide what to keep and what to remove. You’d be amazed at how much space Messages and Videos takes up on your phone.
If you’re running a newer version of iOS on your iPhone SE, you’ll also get some personalized recommendations on how to free up space on your device.
Stop your automatic downloads
Automatic updates are very useful if you are bad at keeping your apps and services up to date with the latest features and fixes. Automatic downloads are useful, but they can also slow down your phone.
If you don’t mind manually updating your apps in the App Store, try turning off Automatic Downloads on your iPhone SE and see if it gives you a boost.
Go to your Settings app and then to the App Store. Once there, turn off Apps & App Updates in the Automatic Downloads section.
You can also disable the other options. You can always turn them back on later.
Clear browser cookies and data
Clearing your browser’s cookies and data frees up memory, which could speed up your iPhone SE.
If you are using Safari on your iPhone SE, go to Settings, then Safari and go to Clear History and Website Data. Give it a tap.
Tapping this button will delete your browsing history, cookies, and other data from Safari. Your history will also be cleared from all other devices signed into your iCloud account. If that sounds good to you, tap Clear History and Data again.
If you are using Google Chrome on your iPhone SE, you need to go to Chrome and tap the three horizontal circles in the lower right corner.
A popup will appear. From there, tap Settings, then Privacy, then Clear Browsing Data. You can now select what you want to remove from your device.
If you notice serious lag on your iPhone SE, you may want to get rid of everything. To do that, select them all and then click Clear Browsing Data.
Kill background refresh
If you have Background App Refresh enabled, your iPhone SE will work to keep your apps updated with new data. It’s a nice feature, but you probably don’t need to enable it for all your apps.
If you don’t want or need apps running in the background, disable this feature. You can disable it completely or you can go through a list and disable it on a case by case basis.
To get this done, go to Settings, then General, then Background App Refresh and disable Background Refresh. If you’d rather pick and choose, you’ll have to go through your list of apps and enable or disable them one by one.
Reset all settings
If none of these solutions work, try factory resetting your iPhone SE. To do this, go to Settings, then General, then Transfer or Reset iPhone, then tap Reset and select Reset all settings at the top.
Make sure you have your Wi-Fi passwords handy before doing this. This makes your iPhone SE forget the known connections.
If the current version of iOS 15 treats your iPhone SE badly, you can try downgrading to an older version, assuming one is available.
If you’re okay with losing weight, check out our guide to downgrading from iOS. It will hold your hand during the whole process.
Erasing your iPhone SE and starting over is a tedious process, but it can have a dramatic effect on the overall performance of your device.
Before taking this step, make sure your data has been properly backed up via Finder/iTunes or Apple’s iCloud service. That way, if you don’t see any improvements, you can easily restore from a backup.
Once you’ve properly backed up, go to your iPhone SE’s settings, then General, then iPhone transfer or reset, then reset, then erase all content and settings and get the ball rolling.
