Free up storage space

If your iPhone feels slow, it may be due to a lack of space on the device. You can check the usage of your iPhone storage by going to the Settings app on "Generally" → "IPhone storage" is typing. In the list of installed apps, look for the apps that take up the most storage space and that you can most likely do without. As soon as you have found a memory-heavy app that you don't necessarily need, tap it and open it "Delete app". Confirm the whole thing again with a tap of your finger "Delete app".

Alternatively, you can tap on "Store app" if you do not want to finally disconnect from the app. This frees up the storage space used by the app, but documents and data are retained so that they can be restored when you reinstall. Under "Recommendations" iOS also suggests optimization measures with which you can quickly free up a lot of storage space manually or automatically in one fell swoop.

Delete messages & attachments

Honestly, who reads old news flows? You should therefore check from time to time which chats you no longer need and delete them. Focus on media-heavy courses, i.e. conversations with lots of pictures, videos and audio messages. In iMessage you delete chat history by adding them swipe left and on the "Clear" Button taps.

If you want to get a more comprehensive picture of the photos, videos, etc. in the respective chat, you can open the conversation by clicking on the profile pic go and that "I" symbol tap. On the next page you will find all the attachments shared in the chat. If you do not delete the entire chat, but z. B. want to get rid of photos and videos, go to the rubric "Photos", tap in the top right corner "Choose" and mark the content with a tap that you want to remove. Then click on in the lower right corner "Clear" and confirms the whole thing again.

Clear Safari Cache

When surfing with the iPhone, a lot of content is downloaded from the Internet and saved in the cache memory. In this way, content can be displayed more quickly when you navigate to websites again. Depending on the amount of data stored, this can affect the speed of the Safari browser. Therefore it makes sense to manually clear the Safari cache every now and then to make the browser faster.

Go to the "Settings" on the menu item "Safari" and tap on there "Clear history and website data". Confirm the whole thing again with a tap on "Delete history and data". If you clear the Safari cache in this way, search data and cookies are also removed in addition to the browser history.

Disable background updates

The background update ensures that you always get the latest content as soon as you open an app. So you will z. For example, current weather data is always displayed as soon as you open the weather app or the latest news is shown when you start a news app. As practical as the background update may be, disabling the feature not only has a positive effect on battery life, but can also help to make a slow iPhone faster again.

To do this, type into the "Settings" on "Generally" and goes up "Background update". You can now specify which apps are allowed to update content in the background and which are not by tapping the switch to the right of the respective application. However, you can also turn off the background update for all apps at once by clicking on "Background update" types and the checkmark at "Out" puts.

Turn off automatic app updates

Similar to the background update, the automatic downloads ensure that your apps are always up to date. This has the advantage that you don't have to worry about updating the numerous applications on your iPhone yourself. However, downloading app updates automatically can also slow down your iPhone. It can therefore make sense to deactivate the function and only update apps manually when necessary.

Open the Settings app, goes on "App Store" and taps on the switch to the right of "App updates"so that it appears grayed out. Your iPhone will no longer update any apps in between.

You can now manually update the app at your own discretion in the App Store App perform by clicking on your top right profile pic and then tap the "To update"-Button next to the respective app presses. With a tap on "Refresh all" you can also update all apps at once if necessary.

Deactivate WLAN search

When you're not connected to a Wi-Fi network, your iPhone is constantly on the lookout for known networks to connect to. Are you z. B. on the move outside in the mobile network, this function makes little sense and consumes valuable computing power, which can have a negative effect on the performance of your iPhone. To make your iPhone faster, you should turn off the WiFi feature in such a case.

Open the Settings app on your iPhone, go under "WIRELESS INTERNET ACCESS" and taps on the switch to the right so that it appears grayed out. Optionally, you can also quickly deactivate the WLAN function via the control center by swiping the screen from bottom to top (up to iPhone 8) or swiping from top right to bottom across the display. Then tap on the WLAN symbol so that it appears on a white background.

Your iPhone can also indicate available networks in your area if you are not currently connected to a WiFi network. Here, too, you can increase the speed of your iPhone by deactivating the search for available wireless networks.

Go to the "Settings" under "WIRELESS INTERNET ACCESS" and taps on the option "Point to networks". Tick ​​the box "Out"so that you are no longer advised of available networks.

Restrict location services & system services

Have you ever wondered how your navigation app always knows where you are or why restaurants and cafes are displayed to you when you google places to eat? The so-called "location services" are responsible for such location-dependent services, which, among other things, also use the GPS function to determine your position. The latter is known to be particularly energy-hungry and can slow down iPhone performance. It therefore makes sense to only activate the location services for those apps for which you really need them, or at least to restrict them. This prevents apps that don't actually need to constantly query their own location.

Go to the Settings app under "Privacy" and choose "Location Services". Below you will find a list of all apps that access your location data. Now tap on an app which, in your opinion, should have no or only limited access to your location data. Then tick either "Never" or "When using the app"to limit the location queries to the use of the app.

But not only apps, but also Apple collects location information as part of the so-called "system services". Here, too, it is worth taking a look at the settings, because the system services also determine your location with the aid of the GPS module.

Go to the Settings app again under "Privacy""Location Services" and scrolls all the way down. Tap on the point "System services"to get an overview of all system services.

It is up to you which functions you deactivate with a tap on the switch. Not all of these background services are important for everyday life, so that you can deactivate options on a trial and error basis in order to check whether you really need them. We find z. For example, that you can do without “Important places” and “Popular nearby”.

By the way: The arrow symbols to the left of the switches indicate which system services have used your location recently or within the last 24 hours.

Delete photos & videos

Over time, most users accumulate tons of photos and videos on iPhone, which take up a large amount of memory and make the device slow. You should therefore check your recordings from time to time and delete unsuccessful or unnecessary pictures and videos.

Go to the Photos app under "Media library" or "Albums" and select an album whose photos and videos you want to delete if necessary. Then tap in the top right corner "Choose", marks the pictures to be deleted with a tap of the finger or a swiping gesture and presses the waste paper bin bottom right. Confirm the process with a tap on "[X] delete objects".

By the way, one way of preventing the memory from being consumed by photos and videos is to use the HEIF / HEVC format. The Apple file format means that pictures and videos take up much less storage space. A photo that would be 5 MB in size as a JPG file needs just 2.6 to 3 MB as a HEIF file. Thanks to a special compression technique, the photo does not lose any of its quality. In this way, you can reduce the file size of your recordings by about half and provide more free space on your iPhone.

Activates the file format in the "Settings" under "Camera""Formats"by ticking the box "High Efficiency" puts.

Note: Activating the option only has an effect new Photos from. Existing images in your recordings will not be converted into the new format. Also note that uploading or sharing recordings in HEIF / HEVC format may cause compatibility problems.

Reduce movement

The parallax effect that z. B. ensures that the app icons on the display move in perspective when the iPhone is tilted, is nice to look at, but consumes power, which in turn can make the iPhone sluggish.

To deactivate this graphic effect, open the "Settings" and taps on the point "Accessibility". Then it opens Move and deactivates the option "Reduce movement"by tapping the switch to the right of it.

Empty RAM

An overloaded memory can also lead to, for. B. Apps run slower or the iPhone feels slow. To make your iPhone noticeably faster in a few seconds, all you have to do is empty the RAM of the iPhone. Proceed as follows:

  1. First open the Camera app on your iPhone.
  2. Immediately close the app again by swiping it up in the app switcher.

iOS manages the memory of your iPhone automatically. You should therefore not constantly empty the RAM of your iPhone in this way, as the system independently takes over the management of the iPhone's RAM and this usually works satisfactorily. However, this trick can help to get the iPhone working again in the event of acute performance problems.

Avoid extreme temperatures

Apple advises in a support document that iOS devices should only be used within the intended operating temperature, which is between 0 ° C and 35 ° C. Accordingly, heat or cold can also affect the performance of the iPhone and slow down the device. If your iPhone feels slower due to the temperature, move it to a cooler or warmer place to restore normal operation temperature and prevent performance degradation.

Change iPhone battery

A slow iPhone can also be the result of an old and worn battery. The performance and capacity of the rechargeable batteries used in the iPhone decrease with age. In combination with the intelligent battery management system of the iPhone, which automatically controls the load on the device, when the battery level is low, processes can be temporarily slowed down. B. Expressed in slower starting apps and a lower frame rate when scrolling. In the case of particularly old batteries, these changes can also be longer-term. In that case, the problem can only be dealt with with a new battery.

You can easily check the battery status of your iPhone in the Settings app under "Battery""Battery condition" check. This is where the entry plays "Maximum capacity" a crucial role. As part of a support document, Apple recommends changing the battery at a maximum capacity of less than 80 percent in order to restore full performance and capacity.

Force restart iPhone

If your iPhone runs slowly despite the tips given here, you should try the universal trick "Hard Reset". This involves a forced restart of the iPhone, with which, as a rule, all kinds of software problems can be dealt with quickly and easily. No personal data is lost and no settings are reset. Only all running processes and iOS are restarted. Temporary malfunctions, system errors or app problems can usually be resolved quickly after a hard reset.
