Thread: iPhone 3G running slow after iOS 4?

If your iPhone 3G is running really slow after installing iOS 4, you’re not alone. While iOS4 is a great OS for newer iPhone models, it makes my older iPhone 3G slow down to a crawl, with everything delayed and stuttering to catch up to touch. At times it’s practically unusable. So what can you do to speed it up? Try the following:

Disable Spotlight on iPhone 3G

If iOS 4 has your iPhone 3G crawling, disable Spotlight search:

• Tap on “Settings”
• Tap on “General”
• Navigate to and select “Home Button”
• Scroll down to “Spotlight Search”
• Disable everything by tapping the check box next to each item
• Exit settings

You can leave some of the Spotlight search items enabled but you will find that the best speed improvement comes from disabling everything.


If you don’t use Spotlight in iOS, disable it!
