Clean up storage if you have many programs running in the background. If you're a frequent user, you've probably amassed quite a collection of digital items by now. Internal storage that is clogged might cause slowdowns and may contribute to the general freezing issue produced by updated iOS software. Make sure you clean up after yourself to make sure this isn't a possibility. To see how much storage you have remaining, go to Settings >General>Storage & iCloud Usage and click Manage Storage. You may properly manage storage from here by eliminating non-system vital data like images, movies, documents, and so on. Following the forced restart, get a chance to access them, quit all of these background apps to make sure none of them is causing conflict.

Install any app updates that are available. Many iOS users are unaware that outdated applications may also create issues. This is especially common following an upgrade, as programs may become incompatible with the new operating system at any time. That's why, after installing an iOS update, it's just as crucial to update applications. Developers should, in theory, distribute updates for their products to avoid problems and incompatibility concerns with new iOS versions, so make sure to download app upgrades as soon as they become available.
