iPhone gets slower and slower: what to do

This is an iPhoneiPhones are the fastest phones you can buy on the market, as well as receiving constant updates that add new features and new optimizations for the battery or the operating system. Unfortunately, even an iPhone can slow down especially if several years pass from the purchase (on average at least 2 years, even if there are very exploited iPhones on the market that slow down after only a year).If unfortunately we ran into a speed problem and we have an iPhone getting slower and slower in the guide that follows we will show you all the tips for seriously speeding up an iPhone following the advice offered by Apple itself or the decades of experience of the best users in the Apple forums.

Change iPhone battery

The first trick to getting a slow iPhone back fast involves changing the internal battery. It may seem disconnected from the speed problem but it actually makes sense: when the battery begins to deteriorate, the iPhone decreases the clock speed of the processor, trying to compensate for the loss of autonomy dictated by the consumption of the internal cells of the lithium battery.

If the battery has too deteriorated the iPhone will become extremely slow. To restore the initial speed of the iPhone let’s take an Apple Store or an R-Store and ask for the replacement of the exhausted battery with a new one.

The operation will have a variable cost based on the model of the iPhone in use, but it is a decisive intervention to restore the full speed of the iPhone. With the new battery, the operating system of the iPhone will remove the limits on the clock frequency of the processor and it will be possible to benefit from the same speed admired when the box is opened.

Delete unnecessary files and apps

If the battery is still new or we can’t spend money to change it, the first trick we can use to speed up an iPhone is to remove the heaviest and most unused apps. To proceed with this simple trick, let’s open the app Settings we press on the menu Generallet’s tap on Space iPhone and identify the heaviest apps that we haven’t used for a few months.

Once the useless app has been identified, select it and press on the item Delete app so as to recover all the space occupied by the app and its data (including files, documents, and files generated during use).

If we have space problems we can delete all the photos that we have already saved on iCloud by taking us to the same path seen above and pressing on Optimize photos, so as to obtain much more space. If instead, we need to delete duplicate photos, screenshots, or blank (black) photos we can use an app like Gemini Photos.

Disable some background apps

On the iPhone, it is not necessary to manually close the apps that we have opened, but on the iPhones, with a few years on their shoulders, it may be a good idea to limit the number of apps that can start in the background at system startup, so as to make the start and the use of the iPhone much faster.

To disable some apps in the background we open the app Settings select the menu General we press on the item Refresh apps in the background and we turn off the switches next to apps that we use little or that we don’t always want to receive notifications. Obviously, we leave the most important messaging apps active (WhatsApp, Telegram, etc.), otherwise, we risk not receiving any more notifications.

Alternatively, we can disable the background app update by simply opening the app Settings and scrolling until you find the name of the app to disable: in the new screen we turn off the switch next to the item Refresh apps in the background to speed up the iPhone.

Disable motion and transparency effect

After following the advice above, we can make the iPhone more responsive and faster by deactivating some graphic effects. These changes make sense on iPhones with at least 2 years on their shoulders: better to give up some graphic gems and regain a faster speed in opening apps and menus.

To proceed, let’s go to the app Settings we press on the menu Accessibility let’s get to the menu Screen effects and we activate the voice Reduce motion. After activating this option it will unlock a new entry just below, that is Fade transitions: we also activate this to get an iPhone with fewer transitions but much faster.

Restrict access to the location

If we have a lot of apps that access the location the iPhone will slow down dramatically, as it increases power consumption. To limit the apps that access the localization, let’s take the path Settings -> Privacy -> Location and check which apps have access to the location with permissions If in use take care to set permissions on May or, alternatively, on Ask next time or when I share.

If, on the other hand, we little use the maps or location apps, we can also greatly increase the battery life by pressing on the individual apps and deactivating the voice. Exact location: from now on the apps will only access the approximate location (based on the location of the mobile data network), thus ignoring the data from the GPS sensor.

Restart or reset an iPhone

Have all the tricks shown so far brought no benefit to the slow iPhone? The latest tricks we can apply on the iPhone to get it back fast as before I am restarting the phone and resetting to factory settings.

To restart, all we have to do is hold down the Power button of the iPhone and slide on the slide that will appear. As soon as the phone is turned off, we wait 5 minutes then turn the phone back on by pressing and holding the same Power button used a little while ago.

We have tried them all but there is no choice but to reset the iPhone. In this scenario we can delete all the apps, settings, and files saved on the iPhone and go back to the factory settings, hoping that this is enough to make the iPhone go back as fast as it used to be.

To proceed, let’s take the path Settings -> General -> Transfer or Erase iPhone we press on the voice Initialize content and settings then click on Continue to start the reset procedure. All personal data will be erased and the phone will be as good as new.

We can learn more about the iPhone reset procedure in our guide on how factory reset iPhones and iPad by deleting data.


Although iPhones have a reputation for being fast phones, it’s best to keep this simple guide handy, so you can apply all the tips right away as soon as you realize your iPhone is getting slower and slower, taking action before the situation becomes. so bad that you have to buy a new phone.

The battery change trick is the most effective to restore the speed of the iPhone but also the other tricks present in the various chapters above can bring great benefits, especially on phones with a few years on their shoulders.
