Apple continues to release updates for iPhone and iPad. However, not everyone likes the latest system. Moreover, some iOS devices cannot carry the newer iOS.

Part 1: Why You Need to Downgrade iOS

There are various reasons why people intend to downgrade iOS to the older version. The most common ones include:

  • 1. Apple keeps introducing new restrictions into the new iOS systems along with new features, such as the latest copyright regulations. Downgrading iOS lets you get rid of such limitations.
  • 2. Most apps lag behind iOS on updating. Once you get the latest iOS, some of your apps may be not available anymore. If you need to access them, you have to downgrade iOS.
  • 3. The latest iOS always contains some new features or new changes, but not everyone prefers to them.
  • 4. As Apple keeps introducing new features into iOS, it becomes larger and larger. So, the old iPhone may not have enough space for the installation. (Learn here to clear iPhone data to get more space.)
  • 5. Though Apple fix bugs in each update, new version of iOS always includes more problems. Some users even encountered black screen and other issues.
