If you’ve upgraded your iPhone, iPad or iPod touch to iOS 8, you may find it a bit sluggish. This article will show you how to improve iOS 8 performance.
Some users have found that iOS 8 slows down performance on older devices. This is most apparent with the iPad 2 and iPhone 4S. The main issue is that there are new features which decrease performance, as they are running in the background. These features not only consume CPU cycles, but also take up network bandwidth. With some minor adjustments, iOS 8 can perform just as well as iOS 7, even on the iPad 2 and iPhone 4S. I have been running iOS 8 on my iPad 2 since the day it was released. I don’t regret upgrading.
Follow “Speed up iOS 7” Instructions
iOS 8 inherited all of the features that came with iOS 7. If you installed iOS 7 and accepted the performance decrease, you may have many of these features running. If you want decent performance from your iOS device, I strongly recommend disabling these features. Before we begin performance tuning your device for iOS 8, follow these instructions.
Wait for Post-Upgrade Optimization to Run
Major iOS releases involve a post-upgrade optimization process. When you first use iOS 8, you may find it unbearably slow. Don’t worry, this is only temporary. Spotlight is indexing the content on your device. This facilitates faster searching. Since iOS introduces new search types to Spotlight, re-indexing is a necessity. There are other optimization processes running — iCloud also needs to exchange information with Apple’s servers. This slows the device by taking up network bandwidth and processor cycles.
With most iOS releases, it usually takes a few minutes to a few hours for the post-optimization process to run. This process seemed to take about a day with iOS 8. I upgraded on the first day of the release. I imagine iCloud servers were overwhelmed, which may have slowed this process down. Expect an older iOS device to run slowly for up to a day after iOS 8 is installed.
There’s not much you can do but wait. In fact, the less you use your iOS device, the faster it will run this process. Don’t turn off your device. Simply ensure that it has enough battery life to run these background processes. Unfortunately, there is no way measure the progress of this process. You’ll know it’s done when your device operates faster.
Remove Recents from App Switcher
iOS 8 adds a new feature to the App Switcher — the ability to easily access recent contacts. This feature makes the App Switcher launch more slowly on older devices. I recommend turning it off. Tap on Settings > Mail, Contacts, Calendars and scroll down to Contacts. Tap on Show In App Switcher and then turn off Recents. For more information on the benefits of turning this feature off, please read “iOS 8: How to Remove Recent Contacts“.
Turn Off or Refine Spotlight Search Options
Spotlight is one of the most useful features on iOS. I use it to launch apps. I find it much easier than scanning dozens of icons. In fact, I cleared the icons off my first home screen, so I can enjoy an unobstructed view of my wallpaper. I just swipe down from the home screen, type in a character or two and launch an app.
iOS 8 adds more features to Spotlight. This means that it must index more content, and this is an ongoing process. Additionally, the more results that Spotlight returns, the slower it will operate. I recommend refining Spotlight to just search for apps. You can always change this back if you need to search for anything else. Most apps have their own search functionality. If you need to search email, you can do that with Mail. Searching for a song can be done within the Music app. (continue…)
