Learn how to do a clean iOS installation and improve your iPhone or iPad performance

IOS is one of the mobile systems that receives the most updates, and that is a very positive point. In addition to always having the latest news presented by Apple even on devices launched more than 2 years ago, they also bring us security fixes that leave us free from many digital dangers.

But it is quite common to hear users complaining that the update left the device slower, or with the battery spending way more than it should (and this happens in ALL updates).

Not everyone knows, but it can happen because of corrupted system files or “rubbish”Temporary that for some reason have not been erased and are accumulating, impairing the performance of the device. And there’s no point in restoring the device and recovering your old backup, because this “trash”Ends up being recovered together, dragging himself forever on his iPhone.

That’s why many recommend doing a “clean installation”Of the system, which usually solves many of the performance problems faced by users.

In this article, we’ll explain to you how to make a clean iOS installation without losing your data.

When Apple releases a new update to the public, it appears on your iPhone or iPad so you can install it right there, without a computer. With this, the device downloads only the files necessary for the update, leaving all data present on the device intact. This is very practical, as you do not need to reinstall all your applications and settings, leaving everything as it was before.

Another way to update iOS is by making a restoration, with the help of iTunes on your computer. In this case, the old system is completely erased and the new one is installed entirely on top, starting from scratch, as when you take the device out of the box for the first time. To recover your data and applications as they were before, you can recover the backup you made before the restoration, and a faithful copy of your old device will be restored to the new system.

It is precisely this backup that can bring old internal files that cause conflicts with the system. Therefore, making the complete restoration of the device without recovering the old backup can clean everything up, making the system run round and the battery until it lasts longer than before. And this type of restoration is what we call Clean Installation, because it’s like starting from scratch on your device.

Full restoration without backup recovery has its strengths and weaknesses, which are listed below:


  • system free of caches and internal waste that needlessly occupy some internal space;
  • cleaning up corrupted files that accumulate over time;
  • opportunity for you to reorganize your applications and get rid of those you hardly use;
  • more responsive and faster system, even on older devices;
  • it is possible that the battery life improves;
  • everything in sync with iCloud is easily recovered, such as contacts, notes, calendars, reminders, photos, Safari passwords, Wi-Fi passwords, iBooks books and PDFs.


  • you need reinstall manually all applications, one by one;
  • the internal data of the apps is not recovered, so those that do not write data to the cloud will be lost;
  • advancing games that are not in sync with the cloud will be lost;
  • your messages and SMS in iMessage will be lost;
  • if you have photos saved in albums, not synced to the iCloud Photo Library and have not saved them before, they may be lost;

Therefore, it is very important to evaluate all the data that may be lost and try to save as much as possible, because as you will not recover the old backup, many of them may disappear.

Before performing the system restore, if you want to keep your records of Cheers and Activity (those on the Apple Watch), then you have to follow another tutorial (on this link) to make a partial backup of this data only.

Well then, let’s get to the main thing: clean iOS installation. You will need:

  • a computer (Mac or Windows)
  • the installed iTunes program (download here)
  • a USB / Lightning cable
  • make sure you have already saved all important data
  • patience

The first thing to do is to connect your device to the computer, via the USB cable. After that, open the iTunes program and click on the icon of the connected device.

Look for the button To restore and click on it to start the process. The program then downloads the system file over the internet and installs it on the device.

At the end of the process, iTunes will ask if you want to restore the backup or if you want to consider it as a “new iPhone“. Choose the latter option.

After the initial settings, your iPhone (or iPad) will be “brand new”, ready to use. When you connect with your iCloud account, all your contacts, calendars, notes and reminders will be synced and retrieved. At this point, it is important to note that iCloud data synchronization is one thing, and the general backup made to the cloud (which contains application data) is another. They are two different things.

From there, you must reinstall all the applications you use. Open the App Store and, in the shopping section, download the ones you want. For many of them (like Facebook, Twitter, Instagram), just log into your account to use it normally, without data loss. THE Whatsapp offers the possibility to recover the backup of the app, which helps a lot (see how to backup WhatsApp by clicking the link). Several other applications store your files in the cloud and also provide access to your old files.

After all this process, you will probably have a more performance device, both in system speed and battery life. Repeat the process at least once a year to get rid of the legacy of old systems.
