Understanding that your iPhone has become slower is quite simple. Animations for scrolling through desktops slow down, applications and games take a long time to open, and in general the smartphone slows down. The reasons for this are also simple.
Why iPhone slows down and how to fix it
1. You just installed a new version of iOS
Don’t rush to scold your iPhone for being slow immediately after the update. The system needs some time to index all files, delete the cache, and optimize its performance and the performance of applications. The smartphone will slow down a little, heat up and discharge faster than usual - this is normal.
Actually, there is nothing to fix here. You just need to wait. It's ideal to update in the evening and leave your iPhone on charge overnight to let iOS do its thing.
2. The disk is almost completely full
Filling your built-in storage to capacity can also be a reason why your iPhone is slowing down. No matter how powerful a smartphone is, the system will inevitably work slower if there are a few free megabytes left on the disk.
Fixing this problem couldn't be easier. All you need to do is delete anything unnecessary or dump photos and videos onto your computer or save them to the cloud. Starting from , it’s convenient to clear free space directly on your smartphone from the “iPhone Storage” menu, which is located in the “General” settings section.
3. You updated instead of installing iOS from scratch
Another reason for slowdowns can be accumulated garbage and bugs from previous versions of iOS. This usually happens if you upgrade your device for several years in a row rather than perform a clean install.
To prevent this from happening, it is better to alternate the update with a clean installation and sometimes flash the iPhone via iTunes without restoring from a backup. It’s better to keep a backup copy just in case. At least in iCloud.
4. Visual effects are enabled on the old device
Modern iOS has many more visual effects and animations than earlier versions. In new devices they do not affect performance in any way, but in older devices they can cause the same slowdown.
The problem is solved by disabling effects, transparency and animations. To do this, open “Settings” → “General” → “Universal Access” and in the “Increase Contrast” item, turn on the “Reduce Transparency” and “Darken Colors” toggle switches.
There, in the “Universal Access” menu, you need to find the “Reduce Motion” item and turn on the toggle switch of the same name in it.
5. Content update enabled
The usability-enhancing background content refresh feature can also cause slowdowns by loading up the processor with tasks even when the iPhone screen is locked. By disabling it, you can slightly improve performance.
To do this, open “Settings” → “General” → “Content Update” and turn off the corresponding toggle switch. It's simple.
6. You are using the minimum required device for current iOS
Apple supports its devices for as long as possible, releasing software updates even for those that are several years old. To prevent older iPhones from slowing down, developers are optimizing iOS. But sometimes this is not enough.
Therefore, if your iPhone is the minimum required to update to a new version of iOS, the best solution is to stay on the current one. For example, for iOS 11, such a device is the iPhone 5s.
7. It just seems to you
As paradoxical as it may sound, decreased iPhone performance can often be just a psychological effect. Knowing that a new, faster iPhone has been released, we begin to think that our old and still good smartphone is slower.
This is just self-hypnosis.
How else to speed up iPhone
To get started, you can use an express method to speed up your iPhone, which will not require any complex manipulations and will only take a few seconds. Life hacker talked about him in.
If none of the above works, it makes sense to try resetting your iPhone to factory settings. The easiest way is to proceed in order: first try to reset the network settings, then all the settings, and then completely erase the device.
Before doing this, of course, you need to back up all your data in iTunes or via iCloud.
If this does not help, there is the last method described in the third section of this article: a clean installation of iOS via iTunes and setting up the iPhone as a new device without restoring from a backup.
Yes, yes, iPhone smartphones can freeze too. You may never encounter this, but the fact remains. However, this is not a problem, since after a reboot the device will most likely resume operation. The problem is different - the iPhone cannot be turned off or restarted in the usual way. Accordingly, the question arises - what to do?
Indeed, if you press the POWER button, nothing will happen.
Apple has come up with a way to reboot the device for such situations. And it consists of this: you need to press not only the POWER button, but also the HOME button, and do this at the same time! Thus, you press the keys and hold them for about 10-20 seconds until the screen goes dark.
As soon as the screen goes dark, you can release the keys. If suddenly the reboot does not take place and the screen goes dark, press the POWER button to turn on your device.
If holding the HOME and POWER buttons for 10-20 seconds does not help, hold them longer. In some cases, this may take a minute or more, but the device should reboot.
Please note that this method works on all iPhones up to 5, 5s, 6, 6 Plus, 6s, 6s Plus. In the case of the iPhone 7 and iPhone 7 Plus, the process is slightly different. The fact is that Apple, starting with these models, abandoned the physical HOME button, so the forced reboot procedure has changed.
If you have an iPhone 7 or 7 Plus, you need to hold down the POWER key and the Volume Down key until the device restarts.
What if the HOME or POWER key doesn't work? Forcefully rebooting a frozen device will not work. In this case, you have only one thing to do - wait until the battery in your iPhone runs out, put it on charge and turn on the device in the usual way.
Today, many people consider the iPhone as simply an ideal device. But I can disappoint you, sometimes the iPhone freezes and users simply don’t know what to do.
In today’s material I will try to talk about my advice on what exactly to do in such situations. Let's consider all the models that currently exist.
My iPhone is frozen and won’t turn off, what should I do?
It would seem that you paid a lot of money and think that, in principle, the iPhone should not only not freeze, but simply never crash or break.
The harsh truth is that some people get bad devices and then the buttons, screens and other things stop working. This is rare, of course, but it happens.
So let's figure out, in order, what exactly to do in such situations. There are not many actions that you can do on your own.
iPhone 4, 4S, 5, 5C, 5S, SE frozen
A smartphone is exactly the same device as a computer. From time to time it can become clogged, become outdated and then freeze.
What we usually do in such a situation is correct - we simply reboot it. The situation is absolutely the same here, the iPhone just needs to be restarted.
Most often this happens on older devices, or on certain versions of iOS when they just added something new.
Therefore, we don’t worry and take the following steps:
- press the button at the same time Home And Lock/Shutdown;
It’s not for nothing that I combined all these devices into one category, because the location of the necessary buttons is in exactly the same place.
So let's reboot and enjoy life. Now you can take a deep breath and relax, you don’t need to buy a new phone.
iPhone 6, 6 PLUS, 6S, 6S PLUS frozen
It would seem that this simply cannot happen with newer devices. But many people make mistakes here, because this happens on raw versions of iOS and in certain situations. 
It is also worth noting that there are many who like to install beta versions of the operating system for no reason.
So, if your iPhone is in a paused state, then go ahead with these steps:
- Home(now it is on the right) and a button Locks;
- We do this until the frozen screen disappears and the apple appears.
Apple has a pretty good rule that the newer the device, the less likely it is for this to happen.
The thing is that only Apple gives users of old gadgets the opportunity to try out the new iOS, and because of this, problems most often occur.
iPhone 7, 7 PLUS frozen
And oddly enough, there have been cases when flagships also hang. And many people probably think that why didn’t I buy something else and spend so much money. 
But I can tell you one thing for sure, despite the fact that Android has long been almost on par with iOS, there are much fewer freezes on Apple’s OS.
After all, here take into account security, which does not allow you to install everything. Although if you behave correctly with any gadget, then everything will be fine.
The reboot scheme has changed a little due to the appearance of the Home touch button, so here's what we do:
- press the button at the same time in the same way Locks and a button Decrease volume;
- everything is the same here until the apple catches fire.
Basically, your iPhone is now operational again and you can use it. This happens sometimes, but if very often and your phone is under warranty, then replace it as soon as possible.
But first you should check if this is not an iOS bug. Perhaps with the update you will be completely fine. Subscribe to any tech blog about this brand and you will always find the information you need there.
iPhone 8, iPhone 8 Plus, iPhone X (10) frozen
Top smartphones also like to lag and freeze, especially when iOS 11 was released. I think many then regretted updating to this version. 
Fortunately, the latest updates are slowly correcting the situation and I think we will soon see a fully functioning operating system.
This year, the controls in new iPhones have changed significantly and this also affected device reboots:
- press and release the button Increase volume;
- press and release the button Decrease volume;
- press and hold the button Locks.
Now this is not done as easily as before, but there is nothing particularly complicated either. This scheme applies to all three models.
What to do if rebooting doesn't help?
All the instructions presented above will only help if something not serious has happened to you. So to speak, the very first aid.
There are too many moments when something bad can happen:
- phone got wet;
- updated the device and it froze;
- other points.
If the most common reboot does not help you, then you can go to the service or simply contact people who understand this.
I don’t advise you to go deeper on your own; most often it ends in a very sad outcome and then your gadget may simply not be saved.
conclusions
In principle, this is probably all the information that I wanted to share with you. Now you know what to do with your iPhone if it just freezes, or even worse, it won’t turn off.
If you have a very old iPhone, I recommend cleaning the RAM from time to time. One of my materials contains this information: .
Each smartphone works in such a way as to perform certain processes. Those, in turn, are created by applications and downloaded by the user if he wants to play his favorite game, for example. Sometimes it happens that there are too many of these processes, and the operating system becomes unable to process such an amount of data. Simply put, the phone freezes and stops processing user commands.
Despite the fact that Apple technology is considered quite reliable and does not cause any inconvenience during use, there are times when the iPhone 5 freezes. What to do in such situations, and how to solve such a problem without harm to the device, we will tell you in this article.
When does freezing occur?
So, as already mentioned, the device may freeze if it is loaded with applications. Specialists from service centers note that this can happen at the very beginning of using phones like the iPhone 5s. “Stuck... What should I do?” - a question arises for any ordinary user. What leads to this is the desire to install more applications and use the functions that the new product offers. Often, the owner of a new phone simply downloads a lot of games with high graphics requirements onto it and launches several at once. While in applications, they continue to load the device. In such cases, the question again arises: “What to do if the iPhone freezes?” More about this later in the article.
What to do if your iPhone freezes?
The device itself provides a standard mechanism for dealing with such situations. When the user does not know what to do if the iPhone is frozen, of course, the first solution, which does not involve any intervention in the operation of the phone, is to simply wait until the processor returns to normal operating mode on its own in a few minutes. It is possible that one or more applications will be closed for this purpose.
If you need the device now, you don’t have time to wait, and your iPhone 4s is frozen and you don’t know what to do, then it’s worth doing the following operation. You must simultaneously hold down the central button located under the screen (it’s called Home - return to the home page), as well as the device’s power off key (on the top panel on the right). In general, this combination is designed to take screenshots of the screen, however, if you hold it longer, an automatic reboot occurs. This is what you need when your iPhone 5 freezes (you don’t know what to do).
It's not the phone that's frozen, just one application.
The methods described above reveal what to do if the iPhone freezes and does not respond to any commands - be it pressing the Home button or trying to lock the screen. In the event that only the application you are currently using is frozen, you should proceed even more simply.
It is enough to press the return button to the home page twice to get to the directory of running applications. The one that is frozen and does not respond to commands needs to be closed, and your device will return to normal operation.
Nothing helps, the phone does not respond
Judging by reviews from users of Apple products, in quite rare cases, but the described actions do not help. This may indicate a more serious problem with the operation of the device. For example, if your iPhone 3 vibrates and freezes, you don’t know what to do - you need to try to connect the gadget to the charger. If the phone starts charging and rebooting, it means that everything is fine - the battery just had a low charge to complete this operation.
If even connecting your iPhone to power did not help it get out of the frozen state, this means that the problem may be at the hardware level. To solve it, you need to take the phone to a service center so that specialists can help you.
How to prevent freezing in the future
In fact, preventing your iPhone from freezing is not that difficult. Since the main reason for such freezes is either the “overloading” of the device with programs that consume too many resources (namely, RAM), or the launch of applications that generate errors (however, this depends solely on the developers).
It turns out that to prevent your iPhone from freezing, you need to monitor how many applications are running in the background, and periodically close them when there is no longer a need for their functioning.
How to speed up the system
If your iPhone freezes quite often and you would like to somehow speed up its operation, we recommend doing some things with it. So, for example, if your device of older generations (models 3, 4 series and earlier) periodically freezes, it’s probably all about the iOS firmware. The thing is that Apple regularly releases updates to its operating system, which consume more and more resources. This is done with the aim of making older models perform worse, which would encourage users to buy new phones. You can solve the problem of slow operation of old devices by refusing updates and rolling back the system to “your” version - the one that was originally installed on the device. It will work much better, you'll see.
Freezing is a problem that any computer equipment faces. At some point, one of the programs begins to behave incorrectly or conflicts with another program, and as a result, the entire device is inoperative. This is exactly the situation that is called freezing.
iPhone is also susceptible to this problem and may freeze from time to time. Typically, when an iPhone freezes, it refuses to turn off or restart, leaving the user confused. Most often, older models such as iPhone 4, 4s, 5, 5s and 6 freeze. But sometimes even iPhone 6s and 7 users experience freezes.
If you find yourself in such a situation, then this material should help you; here you will learn what to do if your iPhone is frozen.
iPhone frozen and won't turn off or restart
Usually, if the iPhone freezes, users try to turn it off or restart it using the standard procedure, namely by long pressing the Power/Lock button. Unfortunately, in most cases, when the iPhone freezes, this shutdown method does not work. The iPhone continues to work and run frozen applications no matter how long the user presses the power button.
But, the iPhone has an alternative shutdown method that bypasses the iOS operating system. Thanks to this, this shutdown method works even on completely frozen devices. The method is to simultaneously press the Power/Lock button.
Home and Power buttons
The “Home” and “Power” buttons must be pressed simultaneously and held until the frozen iPhone turns off. After turning off, you need to wait a few seconds and briefly press the power button once. After this, the iPhone will turn on and start working normally.
It should be noted that the “Home + Power” key combination is also responsible for taking a screenshot. But, to take a screenshot, you need to press these keys literally for 1 second; if you hold the keys longer, the freeze protection will work and the iPhone will reboot.
If you have an iPhone X or a newer model, then you need to use .
iPhone freezes when turned on
Pressing the Home + Power buttons simultaneously allows you to turn the device off and on in any situation. However, this procedure does not guarantee that the iPhone will not freeze again during the startup process.
If your iPhone freezes before the device fully boots up, then you can use a recovery mode called “Recovery Mode”. With its help, you can restore your iPhone to its original state and bring it back to life. But, you need to take into account that this procedure is equivalent to resetting to factory settings and leads to the deletion of all user data.
In order to enter Recovery Mode on your iPhone and perform a recovery, you need to do the following:
- Turn off your iPhone and wait a couple of minutes for all programs to finish their work. If the iPhone does not turn off in the standard way, then you can resort to the “Home + Power” combination described above.
- Next, you need to press the “Home” button and, without releasing it, connect the iPhone to the computer via a Lightning cable.
- Once connected, continue to hold the Home button until the iTunes logo and cable image appear on your iPhone.
- Now you need to release the Home button and launch iTunes on your computer.
- In iTunes, you need to go to the iPhone settings and click on the “Restore iPhone” button.
Restore iPhone button
In this way, you can solve the problem with the iPhone freezing during startup, but, as already mentioned, for this you will need to sacrifice all user files. You can read more about Recovery Mode in our article.
Apple devices also have a so-called DFU or Device Firmware Update mode. If the recovery mode does not help, then you can try and try the recovery again.
