iOS 11 is the most buggy. Why does the iPhone slow down and how can you speed it up?

If the iPhone slows down after an update, then there is nothing terrible or surprising: the phone needs time to set up the new version of the system. Another thing is that older models may not physically withstand the requirements of the latest version of iOS, despite the stated support.

Supported devices

Before installing an update on your phone, you need to understand whether the phone can handle it. The very fact of support indicated in the certificate does not mean anything. Does iPhone 5s slow down after updating to iOS 11? All owners of this model will encounter this, although it is on the list of supported devices.

If the iPhone 5 slows down after the next update, then the reason is most likely the same - lack of hardware resources to work with the new version of the system. Some options do not function; due to improved graphics animation, the interface's response speed to user actions is reduced. Therefore, if your iPhone 5s is slow after updating to iOS 11, then the easiest solution would be to roll back to the previous, tenth version, with which the phone had no problems.

To ensure that the update does not kill the smartphone, it should not be the maximum allowable, but have a small margin. Simply put, if the iPhone 5s slows down after updating to iOS 11, then this is normal and understandable. But if your iPhone 6 slows down after an update, then this is a reason to think that something is wrong with the phone, run diagnostics and fix the problem.

Rollback to a previous version

If the iPhone slows down a lot after updating, it makes sense to roll back to the previous version of the system. The main difficulty is to find a file with this very previous version. If your iPhone slows down after updating to iOS 11, you need to look for the iOS 10.3.3 IPSW file.

Most often, it is not possible to take more than one step back, because when rolling back, iTunes turns to the Apple service to obtain a firmware signature. Old versions do not receive a signature. But Apple developers fully admit that some iPhone 6 slows down after updating to 11, and its owner will want to go back a little, so it’s realistic to take one step. To roll back to a previous version:

After this update, the previous version of iOS will be installed on the phone. If the iPhone 6 slows down after the next update, then this should solve the problem.

Boost your phone

If, after updating, the iPhone began to slow down a lot, and you don’t want to roll back to the previous version, or this does not solve the problem, try troubleshooting in other ways. So, if your iPhone slows down after updating, what can you do:

Reboot the device. First, by normal power off/on, then using Hard Reset, which is performed by holding down the Power and Home keys (volume down on iPhone 7 and higher) until the phone is completely restarted.
Free up memory from unnecessary files and applications.
Update installed applications.
Disable widgets and content updates.
Reduce animation.

If your iPhone slows down after updating to iOS 11, a simple reboot can help get rid of the problems. If even Hard Reset does not fix the problem, check the memory status through the “iPhone Storage” section in the main iOS settings.

Delete unused applications, unnecessary photos, videos and audio recordings, documents so that they do not clog your memory. For normal operation there must be at least 1 GB of free space. The applications you use must be updated. Don't wait for the system to find and install their updates: perform the update manually.

Be sure to go to the Content Update settings section and disable this feature. If it works, then the phone is under constant load and performs several tasks at once, which negatively affects system performance. Don't forget to turn off animation, which adds beauty but wastes precious resources. Turn on motion reduction and transparency enhancement in the Accessibility section of iOS Settings.

We figured out why iPhones slow down after the next update, and looked at how to fix these problems. Now you know that if your iPhone starts to slow down after the next update, you can quickly roll back to the previous version or try to speed it up in other ways.

iPhone owners often complain about problems that arise after installing new software. iOS system updates were no exception to the rule. After installing the update, users noticed that the iPhone was incredibly slow. What is the reason and how to achieve stable operation of the system?

iPhone slows down on iOS 11/iOS 12

Numerous reviews on the Internet from iPhone users report one global problem that many have encountered - After iOS update iOS 11/12, iPhone slows down and even glitches. This manifests itself as follows: the system is very slow, the device takes longer to launch applications or switch between them, response times have increased significantly, system animations run with a delay. In a word, iOS 10.3 is incredibly slow, which is very annoying and interferes with normal interaction with the smartphone.

After updating the iOS system, the iPhone slows down: what to do?

There are several ways to solve this problem. The first one is the most loyal. Just wait a while for the operating system to create a cache and optimize application performance. It is possible that the iPhone will stop glitching and overheating.

The second method involves changing some system settings: for example, disabling visual effects and transparency in the accessibility settings, activating the motion reduction function, disabling background content updating, and deleting junk on the device. After all these steps, the speed and performance of the system should increase.

If none of the methods solved the problem and the iPhone is still slow after updating the iOS system, use the program to enter/exit recovery mode.

iOS 11/iOS 12 slows down on iPhone

Tenorshare ReiBoot is an excellent solution for problems such as black/blue screen, iPhone stuck on the apple logo, display not responding to touch, device rebooting cyclically, etc. The utility will also be an ideal solution in case the system starts to slow down after updating the iOS. The problem is solved in just a few clicks:

1. Download Tenorshare ReiBoot from the official website on Mac or Windows. Install it. Connect your iPhone on board to your computer (or Mac) using a USB cable.

2. Launch the program. You will see several buttons, but only one will be active - “Enter recovery mode.” Click on it and wait for a while. You will see the iTunes logo on your iPhone display.

If your old iPhone is sluggish after upgrading to the new iOS 11, there are several ways to fix the lag.

1. Make room.

An iPhone with full memory or at capacity tends to run slower. You can reduce the load by deleting apps you no longer use and unnecessary photos and videos (or moving the ones you want to save to the cloud). iOS 11 introduces several new tools to help you reclaim your storage space. Go to Settings > General > iCloud Storage & Usage and select Manage Storage under Storage. Here you'll see a colorful chart that shows how much space you're using and how much free space you have left. Below the chart, you'll get several recommendations on how to save storage space, including the newfound ability to offload unused apps, enable iCloud Photo Library, automatically delete old conversations (SMS and attachments that are more than a year old), and view large attachments.

2. Switch to HEIF.

iOS 11 introduces file formats for photos and videos that result in smaller file sizes. Photos use the HEIF format and videos use the HEVC format. If you're like most iPhone users, photos and videos take up the most storage space. Go to Settings > Camera > Formats and select High Efficiency to use the new HEIF and HEVC formats.

3. Update your apps.

Older apps may not run as smoothly or quickly on the new iOS 11 without updating them. After updating your iPhone to iOS 11, check to see if your apps also have updates. Open App Store, tap "Updates" and select "Update All" to update all apps at once.

4. Say no to automatic updates.

Like previous versions, iOS 11 runs processes in the background to make your life easier. For example, apps update themselves in the background, eliminating the need to constantly look at the warning icons on the App Store app icon.

However, updating apps in the background is a process that eats up your device's CPU time (not to mention battery). You can disable this feature and update your apps manually through the App Store app.

To do this, go to Settings > iTunes & App Store and tap the switch to turn off Updates under Automatic Downloads. (The other three options: Music, Apps and Books, and Audiobooks are designed to share downloads among your iOS devices. Any new purchases you make from the iTunes Store, App Store, or iBooks Store are automatically synced across your devices.)

5. Background loading of data by applications.

In addition to updating when you're busy, apps also update their content in the background. For example, your Facebook timeline or Twitter feed will update without your input when you open the app. Of course, this is useful, but it takes time and power from the processor.

To disable this, go to Settings > General > Background app refresh and turn off the toggle switch. Or you can take a custom approach and leave background app refresh turned on at the top and turn it off for individual apps from the list below.

6. Reduce transparency and motion effects.

Apple uses a number of effects to give iOS a sense of depth when you tilt your phone or open and close apps. These motion effects tend to improve the look, but not if they result in choppy animations. To turn off animations, go to Settings > General > Accessibility > Reduce Motion and tap the toggle switch to turn off the effects. You can also turn off autoplay effects in messages, but they add some fun to texting.

Then go back to the Accessibility screen, tap the bar above Reduce Motion under the Increase Contrast heading, and tap the toggle to turn on Reduce Transparency. This setting reduces the effects of transparency and blur, ostensibly to improve readability, but can also speed things up by freeing your device's processor from unnecessary graphics tasks.

7. Limitation of location services.

Location services drain battery life more than they do performance, but if your iOS device is draining your battery faster with iOS 11, it's time to cut down on the number of apps that use your device's GPS to determine your location. iOS 11 gives you more control over how and when apps access your location. App developers will no longer be able to offer only 2 options "Always" and "Never" for tracking options in location services. Now you will be able to choose "When using the application", whether the developer likes it or not. Go to Settings > Privacy > Location Services to configure settings for all your apps that use location services.

8. If in doubt, reboot your smartphone.

When all else fails, you can always try rebooting your device. If your iPhone has been running constantly for days or weeks, give it a break and turn it off and on again. Sometimes a simple reboot can cheer up your phone.

This week, Apple released the second beta version of iOS 11 for iPhone and iPad. Users testing the operating system continue to report errors, low performance, problems with autonomy and operation of wireless modules, as well as application crashes.

These problems with iOS 11 may force users to downgrade to iOS 10. However, you can spend 15-20 minutes of free time and try to improve the operation of the OS.

Restart device

Experience shows that most problems with iOS 11 can be resolved with a simple reboot. Simply hold down the power button and turn off your iPhone or iPad, and then turn the device back on.

Free up memory

If your device has low free memory, it is highly recommended to delete unnecessary data. This will help speed up your device a lot.

Go to Settings -> General -> iPhone Storage. iOS 11 details the distribution of information on the iPhone or iPad. Scroll through the list, see what's taking up the most space, and remove unnecessary content.

Update apps

Typically, older versions of apps are not compatible with new versions of iOS, so it's worth checking the App Store for updates. This, of course, will not fix the problem with programs crashing, but it can still help.

If the update does not help, try reinstalling the problematic application.

Remove unused programs

App incompatibilities affect iOS 11, so it's possible that some apps may be causing the operating system to slow down.

First of all, try removing rarely used software. The process is quite labor-intensive, but in some cases it can help.

Disable widgets

iOS 11 has a lot of widgets. If you do not use interactive interface elements, it is better to disable them. This will speed up your iPhone and iPad.

To turn off widgets, swipe right when you're on the home screen, scroll down, and tap the Edit button. Next, a screen will appear where you can choose which widgets should be displayed and which not.

Disable background updates

If you have background content refresh mode enabled, try disabling it and see if your device runs faster.

When background refresh is enabled, apps constantly update information. This is a fairly resource-intensive option, so disabling it can greatly improve performance.

Go to Settings -> General -> Content Update and disable the feature.

Decrease animation

Sometimes on iOS devices the animation may stutter, in which case it needs to be turned off. To do this, you need to open Settings -> General -> Accessibility and activate the “Reduce Motion” function.

There, in the “Universal Access” item, transparency is reduced and contrast is increased, which can also improve performance.

Download the latest iOS 11

Beta versions of iOS 11 will never be perfect, but with each new update the OS gets rid of bugs. If you don't have the latest version of iOS 11 installed, try updating your operating system. With a 99% chance this will help fix the main problems.

Is your iPhone or iPad glitching, is your iPhone or iPad slow, is your iPhone or iPad freezing? We have collected 13 tips on how to fix these problems!

There are mixed reviews from users that the iOS update has slowed down some iPhones and iPads, or that tasks like opening and interacting with apps are slower after installing the new iOS. If your iPhone or iPad starts to slow down, glitches and freezes after installing iOS, then our tips on how to speed up your iPhone and iPad will help you.

By the way, many of the tips that help speed up your device and get rid of freezes and glitches can also have a positive effect on battery life, so if you're having trouble with the life of your iPhone or iPad, you can also use these tips.

Here we will look at many tips that can help speed up your device. Apart from the first two tips regarding installing software updates, you can skip them if you have already updated your device.

1: Install all iOS and app software updates

To update your iPhone or iPad to a new version of iOS (such as iOS 11.0.2, iOS 11.1, etc.).

Open the Settings app, go to General > Software Update and select Download and install any update on iOS

To receive application updates:

Open the App Store app and go to the Updates tab and install all available app updates.

2: Does the iPhone, iPad glitch, and does the iPhone or iPad slow down after the update?

If you just updated your iPhone or iPad to the latest version of iOS, and the device still slows down, lags and freezes? You can wait while your iOS device re-indexes everything: Spotlight, Siri, Photos and other background tasks. This may cause your device to run slowly due to increased background activity.

It's best to wait a few days, leave the device plugged in, and let it perform all system background tasks. After a night or two, the phone will usually behave normally again and performance will improve, and this will often also fix the fast battery drain issues.

3: Turn off background iOS updates

Background Refresh allows apps to refresh in the background. This is good for multitasking and performance, but it can also slow down system performance. Disabling this is easy and most users won't notice a difference.

Open Settings and go to General > Background App Refresh > OFF

iPhone, iPad glitches and iPhone, iPad slows down

4: Disable Siri App & Siri Look Up

You can often speed up the speed of your device and the Notifications screen by turning off Siri Suggestions and Siri Lookup.

Open Settings and go to Siri & Search, Search Suggestions to OFF, and Look Up Suggestions to OFF.

5: Force reboot your device

Sometimes forcing your device to restart can help improve performance, especially if some strange process is running in the background, or some application is taking a lot of your device and causing your iPhone or iPad to slow down.

For most iPhones and iPads, hold down the POWER and HOME BUTTON simultaneously until you see the Apple logo appear on the screen.

To reboot your new iPhone X, 8, 7, quickly press and release the Volume Up button. Then do the same for the volume down button. Finally, hold the Side button for about 10 seconds until the screen turns black and hold it until you see the Apple logo.

Here's an example of the iPhone 8, which uses the same buttons to force a reboot:

Then just wait for the device to boot again.

6: Use Simple Wallpaper

Using a simple wallpaper created from a small image size can sometimes speed things up. The idea behind using a simple wallpaper is that it requires less memory and system resources, which can help speed up your iOS device's home screen.

Open Settings and go to Wallpaper > Wallpaper > Choose a boring wallpaper that has one color or a very small file size.

The iPhone and iPad are glitchy, and the iPhone and iPad are slow.

The home screen may look a little duller with a simple background image (or not, depending on your taste), but it can also speed up your device a bit. Try it out, you can use the simple tiny gray wallpaper below if you like, or find your own.

7: Disable Parallax Interface Effects and Reduce Motion

iOS uses various visual effects that look stunning but require more system resources to draw and render. Disabling these system UI visual effects may improve performance, or at least improve performance by disabling animations.

Open Settings and go to General > Accessibility > Reduce Motion and turn it on.

The iPhone and iPad are glitchy, and the iPhone and iPad are slow.

*In the Reduce Motion settings, you can also turn off Message Effects for Autoplay, as those animations in the Messages app can also feel a little sluggish at times.

When you turn on Reduce Motion, the effect of opening and closing metering and zooming apps is replaced with a simple, subtle fading animation.

8: Reducing iOS System Transparency

Transparency and blur effects are scattered throughout iOS, from the dock, to the control center, to the notification panels, etc. They look beautiful, but these blur effects can use system resources and sometimes glitch or slow down the iPhone. Disabling them may help the device improve performance:

Open Settings and go to General > Accessibility > Increase Contrast > Reduce Transparency to ON.

Using the Increase Contrast option may seem a little confusing, but the result is that Control Center should work faster.
